    Co-existing two distinct formation mechanisms of micro-scale ooid-like manganese carbonates hosted in Cryogenian organic-rich black shales in South China2023In: Precambrian Research, ISSN 0301-9268, E-ISSN 1872-7433, Vol. 393, article id 107091Article in journal (Refereed)
    Abstract [en]

    Manganese-rich deposits in the lower member of the Datangpo Formation (DTP) (ca. 663–654 Ma) in South China formed in the aftermath of the Cryogenian Sturtian glaciation. The Mn in the DTP occurs dominantly as rhodochrosite and Ca-rhodochrosite. A hydrothermal origin of the Mn2+ is shown by the rare earth element distribution and significantly high Mn/Fe ratios (3–19, average = 10.1). Previous studies suggested a microbially-mediated process for controlling the DTP black-shale hosted Mn carbonate deposits. However, detailed reports on the formation mechanisms of micro-scale (<2–5 μm) ooid-like Mn carbonates in the DTP have rarely been published. Systematic petrography and geochemical analyses in this study demonstrate the coexistence of two types of micro-scale ooidal-like Mn carbonates formed through two distinct mechanisms, either dominated by microbially-mediated or physiochemically-forced pathways. The Type I Mn carbonate has relatively larger grain size of 2–5 μm and exhibits a radial-concentric microfabric that shows signs of growth banding in the form of alternating light and dark laminae, which mainly express variation in Ca and Mn concentrations. The initial precipitation phase of the Type I Mn carbonate is interpreted to be Mn oxide/hydroxide, based on positive Ce anomalies and selective enrichments of particular trace elements. Novel evidence indicates that the capture of Mn as a carbonate phase directly from the water column by primarily precipitated calcite, which is referred to as the Type II Mn carbonate, has also contributed to the DTP Mn-rich deposits. Multiple roles of organic matter in Mn carbonate formation have been established: (1) catalysed Mn-redox cycling; (2) trapping and transportation of initial mineral precipitates to sediments; (3) serving as a carbon source; (4) regulating the morphology of the Mn carbonate. As a key link for understanding Cryogenian carbon and Mn cycling, specific formation pathways for the DTP Mn-carbonates are likely to have been controlled by given atmospheric-oceanic compositions (including oxygen level, pCO2, and redox conditions) in response to major geological and biological events during the interglacial period. In turn, massive storage of inorganic carbon and phosphorous in Mn carbonate phases would have had a substantial influence on biogeochemical carbon cycling during the Cryogenian.

    Circularity evaluation of alternative concepts during early product design and development2020In: Sustainability, E-ISSN 2071-1050, Vol. 12, no 22, article id 9353Article in journal (Refereed)
    Abstract [en]

    Product design and development are essential for a circular transition. Circularity decisions, such as those concerning the type of material, assembly method, and expected lifespan, made during the early design stages will significantly influence a product’s quality, cost, esthetics, sustainability, and circularity performance over the product lifecycle. However, circularity is not often considered in the early stages of product design and development. This paper presents the development of the concept circularity evaluation tool (CCET), which aims to support the evaluation of alternative product concepts in terms of their circularity potential in the early stages of product design and development. The CCET was iteratively developed based on an extensive literature review of the success criteria for tool development, guidelines, and existing tools for circular product design and development and strong collaboration with manufacturing companies. The tool was tested and verified at four manufacturing companies in Nordic countries. The tool has been proven useful for evaluating the circularity of products and supportive in the decision-making process in the early stages of product design and development. © 2020 by the authors.

    An explorative study on respiratory health among operators working in polymer additive manufacturing2023In: Frontiers In Public Health, ISSN 2296-2565, Vol. 11, article id 1148974Article in journal (Refereed)
    Abstract [en]

    Additive manufacturing (AM), or 3D printing, is a growing industry involving a wide range of different techniques and materials. The potential toxicological effects of emissions produced in the process, involving both ultrafine particles and volatile organic compounds (VOCs), are unclear, and there are concerns regarding possible health implications among AM operators. The objective of this study was to screen the presence of respiratory health effects among people working with liquid, powdered, or filament plastic materials in AM. Methods: In total, 18 subjects working with different additive manufacturing techniques and production of filament with polymer feedstock and 20 controls participated in the study. Study subjects filled out a questionnaire and underwent blood and urine sampling, spirometry, impulse oscillometry (IOS), exhaled NO test (FeNO), and collection of particles in exhaled air (PEx), and the exposure was assessed. Analysis of exhaled particles included lung surfactant components such as surfactant protein A (SP-A) and phosphatidylcholines. SP-A and albumin were determined using ELISA. Using reversed-phase liquid chromatography and targeted mass spectrometry, the relative abundance of 15 species of phosphatidylcholine (PC) was determined in exhaled particles. The results were evaluated by univariate and multivariate statistical analyses (principal component analysis). Results: Exposure and emission measurements in AM settings revealed a large variation in particle and VOC concentrations as well as the composition of VOCs, depending on the AM technique and feedstock. Levels of FeNO, IOS, and spirometry parameters were within clinical reference values for all AM operators. There was a difference in the relative abundance of saturated, notably dipalmitoylphosphatidylcholine (PC16:0_16:0), and unsaturated lung surfactant lipids in exhaled particles between controls and AM operators. Conclusion: There were no statistically significant differences between AM operators and controls for the different health examinations, which may be due to the low number of participants. However, the observed difference in the PC lipid profile in exhaled particles indicates a possible impact of the exposure and could be used as possible early biomarkers of adverse effects in the airways.

    Challenges and opportunities with the EU Taxonomy Regulation– with focus on chemical safety and usage in complex products2023Report (Other academic)
    Abstract [en]

    The use of Policy Lab processes has been growing in Sweden and other countries to accelerate the adaptation of regulations to emerging technologies. Policy Lab facilitates active collaboration between relevant authorities, companies, and stakeholders through interactive and iterative methods based on Design Thinking principles. This approach bridges the gap between the legislative domain responsible for developing regulatory frameworks and the innovative companies that create solutions for emerging markets using new technologies and opportunities. In our study, we applied Policy Lab processes to the EU Taxonomy Regulation to identify challenges and opportunities related to chemical safety and usage for manufacturers of complex products. The EU Taxonomy Regulation, along with its delegated acts, represent a serious effort to establish standardized sustainability reporting within EU. However, it is still in its early stages and lacks maturity. Moreover, certain ambiguities within the regulation currently prevent a comprehensive comparison of companies due to the development of other legislations. Addressing these gaps depends on the future development of, for example, REACH. Our conclusion is that the EU Taxonomy Regulation is part of a larger “movement” that reflects the policymakers’ intentions. This intention also includes increased data sharing at a significantly different level compared to current practices. In the long run, the shift will enable authorities to access the data and develop new legislations. Our specific focus was on the objective of pollution prevention and control regarding the use and presence of hazardous substances listed in Appendix C of the EU Taxonomy Regulation. According to Appendix C, activities must not lead to the manufacture, placing on the market or use of listed substances, whether on their own, in mixture or in articles. Regarding listed substances, reference is made to existing EU legislation that regulates hazardous substances within the EU. The most challenging aspect in Appendix C is point (g), which aims to identify substances, whether alone, in mixtures, or in articles, that meet the criteria set out in Article 57 of REACH but are not yet included in the Candidate list. Our workshops, interviews, and literature review confirmed that the main challenge in meeting the criteria of Appendix C, specifically point (g) is the need to enhance transparency and traceability throughout supply chains. Overcoming these challenges requires addressing barriers, such as the lack of a harmonized regulatory framework across the value chain, the need for faster identification and restriction of hazardous substances, and the reinforcement of stronger enforcement measures. The enabling of full declaration of the hazardous properties and functions of the substances, while considering the balance between information disclosure and protecting trade secrets, would reduce the need for extensive tracking of substance of very high concern along the value chain. To improve communication along the value chain and identify data gaps while protecting trade secrets, workshop participants have proposed the use of a user-friendly interface based on traffic light scenario. This interface would serve as a filter mechanism, allowing product manufacturers to establish specific criteria for material suppliers to respond to. The objective is to enhance communication, establish criteria, and effectively identify data gaps. While the SCIP database ensures accessibility of information on articles containing substances from the Candidate List above 0.1 w/w%, it is limited to hazardous substances on that list. This means that hazardous substances not listed in the Candidate List may not be covered by the database. The EU Commission has proposed the implementation of a digital product passport to enhance information sharing about products and their supply chain, including substances of concern. Our study is conducted under the Mistra SafeChem program, where screening tools for hazard and exposure assessment of substances are currently being developed. These tools aim to provide screening data for direct decision-making based on the Defined Approach (DA). These screening tools have the potential to contribute to filling data gaps during the early design phases of complex products, particularly when screening for multiple material alternatives.

    Cylindrical ionization chamber response in static and dynamic 6 and 15 MV photon beams2023In: Biomedical Engineering & Physics Express, E-ISSN 2057-1976, Vol. 9, no 2, article id 025004Article in journal (Refereed)
    Abstract [en]

    Purpose. To investigate the response of the CC13 ionization chamber under non-reference photon beam conditions, focusing on penumbra and build-up regions of static fields and on dynamic intensity-modulated beams. Methods. Measurements were performed in 6 MV 100 × 100, 20 × 100, and 20 × 20 mm2 static fields. Monte Carlo calculations were performed for the static fields and for 6 and 15 MV dynamic beam sequences using a Varian multi-leaf collimator. The chamber was modelled using EGSnrc egs_chamber software. Conversion factors were calculated by relating the absorbed dose to air in the chamber air cavity to the absorbed dose to water. Correction and point-dose correction factors were calculated to quantify the conversion factor variations. Results. The correction factors for positions on the beam central axis and at the penumbra centre were 0.98-1.02 for all static fields and depths investigated. The largest corrections were obtained for chamber positions beyond penumbra centre in the off-axis direction. Point-dose correction factors were 0.54-0.71 at 100 mm depth and their magnitude increased with decreasing field size and measurement depth. Factors of 0.99-1.03 were obtained inside and near the integrated penumbra of the dynamic field at 100 mm depth, and of 0.92-0.94 beyond the integrated penumbra centre. The variations in the ionization chamber response across the integrated dynamic penumbra qualitatively followed the behaviour across penumbra of static fields. Conclusions. Without corrections, the CC13 chamber was of limited usefulness for profile measurements in 20-mm-wide fields. However, measurements in dynamic small irregular beam openings resembling the conditions of pre-treatment patient quality assurance were feasible. Uncorrected ionization chamber response could be applied for dose verification at 100 mm depth inside and close to large gradients of dynamically accumulating high- and low-dose regions assuming 3% tolerance between measured and calculated doses. © 2023 The Author(s).

    Time Series Clustering for Knowledge Discovery on Metal Additive Manufacturing2020In: 21th International Conference on Intelligent Data Engineering and Automated Learning, IDEAL 2020, Springer Science and Business Media Deutschland GmbH , 2020, p. 447-455Conference paper (Refereed)
    Abstract [en]

    This work meets Metal Additive Manufacturing and Time Series Processing. It presents a four-step analytical procedure addressed to support the discovery of defect causes in 3D metal printing. The method has a phase of data space transformation, where the features space is firstly reduced and secondly exploited in a higher dimensional space. Later, a procedure for knowledge discovery is applied. Finally, by analyzing the results, it is concluded the most probable causes of the high rate of defects in the production phase. This procedure is proved with data obtained from a SLM machine, and the results are convincing.

    Scaling up and scaling down: Improvisational handling of critical work practices during the COVID-19 pandemic2022In: Management Learning, ISSN 1350-5076, E-ISSN 1461-7307Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to explore improvisational handling of critical work practices during the COVID-19 pandemic and interpret these practices from a learning perspective. Based on an interview study with representatives of private, public and intermediary organisations, the study identified three different types of improvisational handling as responses to the pandemic crisis involving ‘scaling up’ and ‘scaling down’ critical work practices. By ‘scaling up’ and ‘scaling down’, we refer to practices for which, due to the pandemic, it has been imperative to urgently scale up an existing operational process or develop a new process, and alternatively extensively scale down or cease an existing process. The types of improvisational handling differed depending on the discretion of involved actors in terms of the extent to which the tasks, methods and/or results were given beforehand. These types of improvisational handling resulted in temporary solutions that may become permanent after the pandemic. The framework and model proposed in the article can be used as a tool to analyse and learn from the changes in work practices that have been set in motion during the pandemic. Such learning may improve the ability to cope with future extensive crises and other rapid change situations. © The Author(s) 2022.

    Interactive research in production start-up—application and outcomes2020In: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 31, no 8, p. 1561-1581Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to reflect on interactive research as a means to create relevant knowledge in the domain of operations management in general and specifically in the context of production start-up. Design/methodology/approach: The reflection on the use of interactive research in production start-ups was based on a study of two completed interactive research projects. The lens for reflection was a framework including context, quality of relationship, quality of the research process itself and outcomes. Findings: The context was industrial manufacturing companies in Sweden, with different kind of challenges related to production start-ups, such as collaboration between involved functions and suppliers, competence development and work routines. Indicators of the quality of relationship between researchers and practitioners were initiated development activities and new collaboration between functions, within the company, between companies and in supply chains. The reflection of the quality of the research process itself was based on an interactive research process including four iterative steps with regular follow-ups allowing joint practitioner and researcher reflection on the progress. Identified outcomes included increased awareness and competence on how to deal with production start-ups, improvements of communication, work procedures and structures, better use of competences, increased cross-functional dialogue and cultural understanding. Practical implications: Implications for practitioners are the possibilities for knowledge creation through interactive collaboration in research projects enabling exchange between researchers from complementary fields and other companies dealing with production start-ups. Originality/value: The interactive research approach enables joint knowledge creation in a fast-changing context such as production start-ups as well as value-adding results both for practitioners in industry and for academia.

    Systematic Green Design in Production Equipment Investments: Conceptual Development and Outlook2023In: IFIP Advances in Information and Communication Technology, ISSN 1868-4238, Vol. 692 AICT, p. 174-188Article in journal (Refereed)
    Abstract [en]

    This paper explores the concept of green design in the context of production, focusing on investment projects for production equipment design and acquisition by a manufacturing firm. Research towards making manufacturing and production related activities more sustainable is increasing. In the manufacturing sector, environmental sustainability tends to be more commonly approached from the operations perspective. However, the decisions taken in the design phase of the production equipment significantly impact the operations phase. Therefore, proactive design approaches for sustainability applied in product design settings could be transferred to the design of the production equipment to build in green aspects from the outset. This study explores the research questions of what green production equipment design entails and how the concept of green design has evolved in the context of production. Overall, this conceptual paper highlights the importance of incorporating green design principles from the outset of the production design. Transferable methodological issues are also explored for further detailed investigation in the production equipment design context. Strong collaboration between equipment suppliers and the buying manufacturer that aims to integrate sustainability as part of requirements is proposed as an enabler for the way forward. The paper also provides insights into the evolution of the concept in this context for possible future research.

    Ämnen som hindrar eller försvårar återvinning av plast i prioriterade produktgrupper inom byggsektorn2023Report (Other academic)
    Abstract [sv]

    I detta uppdrag undersöker vi kemiska tillsatser i plaster som försvårar eller utgör hinder för återvinning av materialet. I denna rapport avser kemiska tillsatser additiv som medvetet introducerats i produkten eller materialet, och det är dessa kemiska ämnens natur som avgör problematiken ur återvinningssynpunkt. Vi fokuserar på byggsektorn eftersom denna sektor använder stora mängder plast av hög kvalité. Trots detta är återvinningsgraden för plast låg och potentialen att öka återvinningsgraden är därmed stor. Ett materials potential för återvinning bestäms av flera faktorer, varav kemikalieinnehåll är en. Det är viktigt att tänka på vilken eller vilka produkter plasten är lämplig att återvinnas till, och hänsyn måste alltid tas till gällande kemikalielagstiftning för just de produkttyperna. Kemiska ämnen som kan vara skadliga för människan och/eller miljön är särskilt viktiga att utreda, men det finns också andra tillsatser i material och produkter som försvårar återvinningsprocessen eller påverkar kvalitén på den återvunna plasten negativt så att marknaden för det återvunna materialet blir begränsad. Ytterligare en faktor att ta i beaktande är hur exponeringen för kemikalierna ser ut, om de är bundna i plasten eller kan emitteras och utsätta människor och miljön för direkta risker. De stora kategorierna i denna kartläggning har varit golv, rör och rördelar, kablar, profiler och lister, isoleringsmaterial, samt tätningsskikt. För dessa produktgrupper dominerar polymertyperna PVC, PE av olika densitetsgrad och comonomer-innehåll, PP (homo- och copolymer), PS och PUR. Då härdplaster, där även PUR ingår, förekommer i form av lacker, adhesiv och ytbeläggningar i byggprodukter behandlas dessa också övergripande. Många materialströmmar finns tillgängliga för återvinning inom kategorin byggplast generellt sett, men möjligheterna och incitamenten att sortera ut dessa i sina ursprungliga fraktioner är låg. Detta beror antingen på att efterfrågan på mekaniskt återvunnet material i dessa produktkategorier inte är stor nog, som för PEX och vissa typer av rör, eller på att volymerna är för låga för lönsamhet. Ett exempel på det sistnämnda är profiler och lister av PVC där etablerad cirkulär återvinning finns ute i Europa, men produktkategorin är för liten i Sverige för att drivkraften ska uppstå. Eftersom flera av de polymermaterial och produkter vi kartlagt i denna rapport har en historisk användning av idag reglerade, eller till och med förbjudna kemiska ämnen, kompliceras återvinningen av byggplast i att de inkommande avfallsströmmarna är av mycket varierande ålder. För att möjliggöra en högre återvinningsgrad och bättre kvalitet krävs därför utökad och mer noggrann sortering så att problematiska, och i vissa fall hälso- och miljöfarliga, innehållsämnen inte följer med i den mekaniska återvinningen, men inte heller så att kvalitativa fraktioner av en viss produkt- och polymertyp avvisas från återvinning av säkerhetsskäl. Ett axplock av problematiska tillsatser är tungmetallstabilisatorer och mjukgörare i produkter av PVC, flamskyddsmedel i isolering av EPS och XPS, samt silanförnätad PEX som innehåller tennkatalysator. Kontaminering i form av härdplastrester, felsorterad PEX i PE-recyklat, samt tejper och fogar på tätskikt utgör de mer oavsiktliga, fysiska hindren för kvalitetsmässig återvinning tillsammans med faktumet att en stor del av kablar och rör helt enkelt inte utvinns ur marken efter sin användningstid. Sammanfattningsvis skulle fler fraktioner av byggplast kunna återvinnas mekaniskt genom att stärka infrastrukturen kring insamling och sortering, men för detta krävs ökad efterfrågan och långsiktig lönsamhet. Kemiska återvinningsmetoder seglar upp som en möjlig lösning för flera av de hinder som identifieras i denna studie, till exempel tvärbundna material, material med hög andel fyllmedel, eller för avskiljning av oönskade tillsatser likt tungmetaller och ftalater. Kartläggningen av detta område får därför ses som en intressant frågeställning för ytterligare arbete.

    Det inkluderande, hållbara och uppkopplade samhället : Utvärdering och framtidsanalys2023Report (Other academic)
    Abstract [sv]

    Södertälje kommun har höga ambitioner att drastiskt sänka sin klimatpåverkan och har ambitionen att inte ha några nettoutsläpp av växthusgaser år 2030 (Södertälje kommun Miljö- och klimatstrategi 2022–2030, 2022). För att nå dessa mål spelar avfallssektorn i Södertälje kommun en avgörande roll, vilket också innebär ett behov av större involvering och ett större engagemang från medborgare och företag. Som en del i det arbetet skapades projektet Det inkluderande, hållbara och uppkopplade samhället. Projektet är ett samarbete mellan Södertälje kommun, Telge Återvinning, RISE Research Institutes of Sweden och Umeå Universitet och avser att undersöka hur maskingenererad data kan ha dubbel nytta i att både skapa externt medborgarvärde och internt organisatoriskt värde i Södertälje kommuns omställning till en hållbar stad. Denna rapport inkluderar en nulägesanalys över tre tematiserade områden; digitalisering, livscykelanalys (LCA), och medborgardialog. Södertälje kommun har tillsammans med Telge Nät byggt upp ett så kallat LoRaWAN2 (ett trådlöst nätverk med dubbelriktad kommunikation3) i Södertälje för att underlätta kommunikation mellan sensorer i uppkopplade enheter. 169 papperskorgar har också försetts med sensorer som mäter fyllnadsgrad, vilket genererat ett proof-of-concept för hur uppkopplad utrustning kan möjliggöra ruttoptimering och placeringsplanering. Att koppla upp en papperskorg har i det här fallet inneburit att man fäster en sensor i locket på befintliga kärl.

En LCA har genomförts för att utvärdera miljöpåverkan från sakernas Internet i Södertälje centrum för smart sophämtning ur ett livscykelperspektiv. Med koppling till kommunens klimatstrategi har miljöpåverkan med fokus på klimatpåverkan prioriterats. Den visar att IoT-systemet enbart utgör en liten del av klimatpåverkan (122 kg CO2-ekv per år4), vilket främst härrör från gateways (50%) och sensorer (27%) och användning av Internet (23%). Sophämtningen bidrar med cirka 12 ton CO2-ekv per år, vilket främst bidrog till användningen av fossilbaserade avfallspåsar i plast (96%) och Hydrerad Vegetabilisk Olja (HVO)-baserade transporter (4%). Vidare visar LCAn att potential för framtida klimatsmart sophämtningssystemet ligger inom minskad användning av fossila plastpåsar och smart planering av sophämtning för att reducera transporter. Södertälje har redan minskat sin klimatpåverkan från transporter (under 2016) genom byte från diesel till HVO. För ett system med 169 papperskorgar (studiens utgångspunkt) innebar detta 83% minskning, från 2,3 ton till 380 kg. Enbart två ton av denna minskning härrör från fossilfria transporter (resp. 8,75 ton för ett möjligt framtida system med 700 papperskorgar). Dock visar resultaten att ännu mer klimatpåverkan kan minskas genom att inte använda fossila plastpåsar, nästan 12 ton (resp. 50 ton för 700 papperskorgar). Detta motsvarar fem resor till Thailand (2,5 ton per resa) eller utsläpp för fyra invånare (2,8 ton per invånare) för året 2030. För ett system med 700 papperskorgar betyder det minst 20 resor till Thailand eller utsläpp för upp till 20 invånare per år. Vidare har projektet ett fokus på inkludering av medborgare i frågor kring hållbarhet, med syftet att informera, engagera och inkludera medborgare i målet med att uppnå hållbar resurshantering. Medborgardialog kan ske på många olika vis och innebära olika saker. Nulägesanalysen visar att flera olika aktiviteter genomförts på området, och att dessa framförallt kan kopplas till kategorierna ”information” och ”konsultation”, men där också det finns kommande inslag av ”dialog” med till exempel det Hackathon som planeras. Från nulägesanalysen noterades dock en möjlighet till utökat fokus på medborgardialog i Södertälje, samt att det finns en medvetenhet om behovet av att inkludera många olika grupper i denna dialog, men det noterades även en utmaning vad gäller inkludering och olika språk.

    Det inkluderande, hållbara och uppkopplade samhället: Nulägesanalys2021Report (Other academic)
    Abstract [sv]

    Södertälje kommun har höga ambitioner att drastiskt sänka sin klimatpåverkan och har målet att inte ha några nettoutsläpp av växthusgaser år 2030. För att nå dessa mål spelar avfallssektorn i Södertälje kommun en avgörande roll, vilket också innebär ett behov av större involvering och ett större engagemang från medborgare och företag. Som en del i det arbetet skapades projektet Det inkluderande, hållbara och uppkopplade samhället. Projektet är ett samarbete mellan Södertälje kommun, Telge Återvinning, RISE Research Institutes of Sweden och Umeå Universitet och avser att undersöka hur IoT-genererad data kan ha dubbel nytta i att både skapa externt medborgarvärde och internt organisatoriskt värde i Södertälje kommuns omställning till en hållbar stad. Denna rapport inkluderar en nulägesanalys över tre tematiserade områden; digitalisering, livscykelanalys (LCA), och medborgardialog. Södertälje kommun har tillsammans med Telge Nät byggt upp ett så kallat LoRaWAN (ett trådlöst nätverk med dubbelriktad kommunikation) i Södertälje för att underlätta kommunikation mellan sensorer i uppkopplade enheter. 169 papperskorgar har också försetts med sensorer som mäter fyllnadsgrad, vilket genererat ett proof-of-concept för hur uppkopplad utrustning kan möjliggöra ruttoptimering och placeringsplanering. Att koppla upp en papperskorg innebär i praktiken att man fäster en sensor i locket på befintliga kärl. Denna sensor känner sedan av fyllnadsgraden i papperskorgens plastpåse med jämna mellanrum. Initiativet kring uppkopplade papperskorgar har medfört inlärning på flera nivåer – såväl utvecklarna som utformar sensorerna, som medarbetarna som förlitar sig på dem, har behövt tänka i nya banor och ompröva invanda arbetssätt. Värt att notera är att personalen behöver besöka samtliga områden där papperskorgar finns trots sensortekniken i och med att deras arbetsuppgifter även inkluderar renhållning av gator och vård av grönytor. Det vill säga, det föreligger i nuläget inte en kvantitativ ekonomisk vinst utan snarare en kvalitativ nytta i form av en potentiellt renare stad. Bland de system som Södertälje kommun använder ses två som särskilt intressanta i relation till Sakernas Internet enligt denna nulägesanalys. På en operativ nivå har Infracontrol potential att anta rollen som ”spindeln i nätet” där status på uppkopplad utrustning kan hanteras.

Denna rapport har fokus på nulägesanalys. I och med denna analys går projektet sedan in i en ny fas, med fokus på test och utvärdering av koncept, med ett fortsatt fokus på digitalisering, miljöbedömning och medborgardialog. Ett hackathon, Hack for Södertälje, planeras också på projektets tema: Det inkluderande, hållbara och uppkopplade samhället.

    Den cirkulära bilen (förstudie)2023Report (Other academic)
    Abstract [sv]

    Syftet med förstudien Den cirkulära bilen var att börja bygga konkreta visioner som möjliggör att Sverige har en cirkulärt anpassad bilflotta med fossilfria och klimatneutrala transporter år 2045 och att bygga en solid bas för ett steg 2-projekt, som i sin tur kommer att ge stöd och kapacitet för aktörer att accelerera den cirkulära bilvärdekedjan. Projektet har samlat 13 parter från hela värdekedjan och gemensamt lagt grunden till vidare arbete i ett fortsättningsprojekt – en ansökan som genererat intresse från ett stort antal parter både befintliga och nytillkommande. Inom studien har startmöten och workshops genomförts där parter samlats digitalt och frågeställningar sonderats. Intervjuer har genomförts med parter där möjligheter och utmaningar med omställningen diskuterats. Studiebesök har genomförts där kunskapsdelning skett och samverkan möjliggjorts. Fysisk workshop har genomförts med samtliga parter. Här tittade man gemensamt på trender och möjliga framtidsscenarios genom hela systemet. Detta gav en bra grund för det vidare arbetet med steg 2. Förstudien har genererat stort intresse från aktörer i hela värdekedjan, skapat nya kontakter och möjligheter till samverkan och blivit uppstarten på en gemensam kunskapsresa för verklig förändring. Studien har initierat arbete brett i värdekedjan kopplat till gemensamma frågeställningar samt framtidsspaningar, vilket möjliggör gemensamt arbete för bred omställning och tydliggjort behovet av åtgärder som förflyttar hela systemet. Detta ses som en god grund för ett steg 2 projekt med förutsättningar för att förverkliga den cirkulära bilvärdekedjan.

    A novel zirconia-based composite presents an aging resistant material for narrow-diameter ceramic implants2021In: Materials, ISSN 1996-1944, E-ISSN 1996-1944, Vol. 14, no 9, article id 2151Article in journal (Refereed)
    Abstract [en]

    A novel ceria-stabilized zirconia-alumina-aluminate composite (Ce-TZP-comp) that is not prone to aging presents a potential alternative to yttrium-stabilized zirconia for ceramic oral implants. The objective of this study was to evaluate the long-term stability of a one-piece narrow-diameter implant made of Ce-TZP-comp. Implant prototypes with a narrow (3.4 mm) and regular (4.0 mm) diameter were embedded according to ISO 14801, and subgroups (n = 8) were subsequently exposed to dynamic loading (107 cycles, 98N) and/or hydrothermal treatment (aging, 85◦C). Loading/aging was only applied as a combined protocol for the 4.0 mm diameter implants. One subgroup of each diameter remained untreated. One sample was cross-sectioned from each subgroup and evaluated with a scanning electron microscope for phase-transformation of the lattice. Finally, the remaining samples were loaded to fracture. A multivariate linear regression model was applied for statistical analyses (significance at p < 0.05). All samples withstood the different loading/aging protocols and no transformation propagation was observed. The narrow diameter implants showed the lowest fracture load after combined loading/aging (628 ± 56 N; p < 0.01), whereas all other subgroups exhibited no significantly reduced fracture resistance (between 762 ± 62 and 806 ± 73 N; p < 0.05). Therefore, fracture load values of Ce-TZP-comp implants suggest a reliable intraoral clinical application in the anterior jaw regions. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

    Fracture resistance and crystal phase transformation of a one- and a two-piece zirconia implant with and without simultaneous loading and aging—An in vitro study2021In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 32, no 11, p. 1288-1298Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate the influence of artificial aging on the transformation propagation and fracture resistance of zirconia implants. Methods: One-piece (with integrated implant abutment, 1P; regular diameter [4.1mm]; n = 16) and two-piece (with separate implant abutment, 2P; wide diameter [5 mm]; n = 16) zirconia implants were embedded according to ISO 14801. A two-piece titanium–zirconium implant (Ti-Zr; 4.1 mm diameter) served as a control (n = 16). One subgroup (n = 8) of each system was simultaneously dynamically loaded (107 cycles; 98N) and hydrothermally aged (85°C, 58 days), while the other subgroup (n = 8) remained untreated. Finally, specimens were statically loaded to fracture. Potential crystal phase transformation was examined at cross sections using scanning electron microscopy (SEM). A multivariate linear regression model was applied for statistical analyses. Results: The fracture resistance of 1P (1,117 [SD = 38] N; loaded/aged: 1,009 [60] N), 2P (850 [36] N; loaded/aged: 799 [84] N), and Ti-Zr implants (1,338 [205] N; loaded/aged: 1,319 [247] N) was not affected significantly by loading/aging (p =.171). However, when comparing the systems, they revealed significant differences independent of loading/aging (p ≤.001). Regarding the crystal structure, a transformation zone was observed in SEM images of 1P only after aging, while 2P showed a transformation zone even before aging. After hydrothermal treatment, an increase of this monoclinic layer was observed in both systems. Conclusions: The Ti-Zr control implant showed higher fracture resistance compared to both zirconia implants. Loading/aging had no significant impact on the fracture resistance of both zirconia implants. The wide-body 2P zirconia implant was weaker than the regular body 1P implant. © 2021 The Authors.

    Nature-Inspired Peptide Antifouling Biocide: Coating Compatibility, Field Validation, and Environmental Stability2023In: ACS Applied Bio Materials, E-ISSN 2576-6422, Vol. 6, no 6, p. 2415-2425Article in journal (Refereed)
    Abstract [en]

    This study reports the development of a class of eco-friendly antifouling biocides based on a cyclic dipeptide scaffold, 2,5-diketopiperazine (2,5-DKP). The lead compound cyclo(N-Bip-l-Arg-N-Bip-l-Arg) (1) was synthesized in gram amounts and used to assess the compatibility with an ablation/hydration coating, efficacy against biofouling, and biodegradation. Leaching of 1 from the coating into seawater was assessed via a rotating drum method, revealing relatively stable and predictable leaching rates under dynamic shear stress conditions (36.1 ± 19.7 to 25.2 ± 9.1 ng-1 cm-2 day-1) but low or no leaching under static conditions. The coatings were further analyzed using time-of-flight secondary ion mass spectrometry (ToF-SIMS), with 1 seen to localize at the surface of the coating in a surfactant-like fashion. When coatings were deployed in the ocean, detectable reductions in biofouling development were measured for up to 11 weeks. After this time, biofouling overwhelmed the performance of the coating, consistent with leaching kinetics. Biodegradation of 1 in seawater was assessed using theoretical oxygen demand and analytical quantification. Masking effects were observed at higher concentrations of 1 due to antimicrobial properties, but half-lives were calculated ranging from 13.4 to 16.2 days. The results can rationally inform future development toward commercial antifouling products.

    Value Chains vs. Ecosystems: Current Perspectives among Swedish SMEs Entering the Interconnected World of IoT2020In: Advances in Transdisciplinary Engineering at SPS2020, IOS Press BV , 2020, p. 489-500Conference paper (Refereed)
    Abstract [en]

    Smart connected industrial products and the Internet of Things (IoT) are transforming the industrial business landscape in a radical way. To reach the full potential of IoT-Technologies manufacturing firms are forced to rethink almost every aspect of their value creation process. To utilize this promising digital technology and to cope with the new market conditions of IoT environments, research shows that industrial firms have to make a fundamental shift in value creation logic and break free from the value chain perspective of business. Instead they have to embrace a view where value is co-created within ecosystems in both a vertical and a horizontal manner. By exploring the value creation logic of small and medium sized (SME) Swedish industrial machinery manufacturers, this study contributes to a deeper understanding of how manufacturing firms view their value creation processes and how aligned this logic is to the latest research in IoT. The study found that Swedish industrial machine manufacturers do understand the transformative force of IoT-Technologies and see great business opportunities to utilize IoT in their business. The study, however, identified a lack of co-creation and difficulties in embracing an ecosystem perspective. While quick to embrace change on a technical level, respondents still adhere to a firm-centric and linear perspective of value creation, with a strong attachment to the value chain concept. The study suggests that it is not a lack of technical proficiency or engineering know-how, but rather an adherence to goods-dominant logic and attachment to the value chain concept that prevent Swedish SME manufacturers from fully embracing the growing market of industrial IoT. Hence, we see an urgent need for both practitioners and academia to shift their attention from the dazzling potential of cutting-edge technologies to the nitty-gritty business of incorporating co-creation and ecosystem-Thinking into current business practices. © 2020 The authors.

    Digital Tools and Information Needs Assessment for Efficient Deviation Handling in SMEs2020In: Advances in Transdisciplinary Engineering at SPS2020, IOS Press BV , 2020, p. 24-35Conference paper (Refereed)
    Abstract [en]

    In a time of change focusing on the application of technology, there is a high risk of underestimating the compliance of internal needs and adaption to context. The research study employs a qualitative approach using the case study methodology. The source of data comes from five different manufacturing companies categorized as Small to Medium Size Enterprises (SMEs). A multidisciplinary team performed semi-structured interviews and fieldwork at each site, along with regular online meetings with the partners. The study employs five dimensions of the information quality perspective to assess information utilized to support deviation handling and connects the information quality deficiencies to the digital tools' impact. The empirical findings indicate the need for the companies to perform a requirement analysis of information needs before the adoption of digital systems or digital tools, to assess their current state in terms of data and information. The paper discusses the impact digital tools may have on deviation management in SMEs and under which circumstances digital tools could improve deviation management. Lastly, this paper intends to shed light on the utilization of digital technologies for disturbance handling on the production shop floor. © 2020 The authors

    Enabling the twin transitions: Digital technologies support environmental sustainability through lean principles2023In: Sustainable Production and Consumption, ISSN 2352-5509, Vol. 38, p. 13-27Article in journal (Refereed)
    Abstract [en]

    Manufacturing companies seek innovative approaches to achieve successful Green and Digital transitions, where adopting lean production is one alternative. However, further investigation is required to formulate the strategy with practical inputs and identify what digital technologies could be applied with which lean principles for environmental benefits. Therefore, this study first conducted a case study in three companies to collect practice-based data. A complementary literature review was then carried out, investigating the existing frameworks and complementing practices of digitalized lean implementations and the resulting environmental impact. Consequently, the Internet of Things and related connection-level technologies were identified as the key facilitators in lean implementations, specifically in visualization, communication, and poka-yoke, leading to environmental benefits. Furthermore, a framework of DIgitalization Supports Environmental sustainability through Lean principles (DISEL) was proposed to help manufacturing companies identify the opportunities of digitalizing lean principles for Environmental sustainability, thus enabling the twin transitions and being resilient. © 2023 The Authors

    Life cycle assessment of Internet of Things(IoT) solution in Södertälje municipality– A smart waste collection system2021Report (Other academic)
    Abstract [en]

    Internet of things (IoT) is expected to transform the way we live, work, and learn. Using IoT can be a game-changer for municipalities to move towards sustainability. Within the Vinnova financed project, the municipality wants to explore how IoT can enable route optimization and placement planning for increased operational efficiency. The aim of this study is to enhance the knowledge of the environmental benefits of IoT systems in the waste collection system in the city center of Södertälje. This life cycle assessment, LCA, will support the project by identifying environmental hotspots. The LCA study was performed in Jan-Sep 2021. The functional unit of the study has been set to 1 year of IoT system service for 160 litter bins in city center of Södertälje. The studied system is a cradle-to-grave system, including raw materials, sensors and gateways, use phase, and end of life the sensors and gateways, internet connection, as well as the cloud services. Inventory information have been collected mainly from Södertälje, suppliers, and the service providers. Generic data, such as electricity mix, and transports have been taken from the Ecoinvent database and literature. This study has evaluated the environmental impacts of IoT system in Södertälje for the case of smart waste collection system installed in the city center in a life cycle perspective. The objective of the study has been: 1. To estimate the environmental impact (with focus on climate change impact) of IoT system in Södertälje and find out the hotspots within the system in a life cycle perspective. The climate change impact of the IoT system solution in Södertälje is estimated about 120 kg CO2eq per year, which mainly contributes from the gateways (50%) and sensors (27%) and the use of internet (23%). 2. To estimate the environmental impact (focus on climate change impact) of the waste collection system (without IoT system) and find out the hotspots within the system. The climate change impact of the current waste collection system in the city centre of Södertälje contributes approximately 12t CO2eq per year, which mainly contributed from the use of fossil-based plastic trash bags (96%) and the HVO based transport (4%). 3. To compare the current with the future waste collection system (including IoT system for planning and service). To compare the current with the future waste collection system, we use scenarios (see Figure 20 for results). At the starting point of the study (scenario 1), we present results that are based on assumptions and have the same CO2 emissions for the transport and the trash bags. The results were based on diesel (50%) and recycled plastic trash bags (50%). The recycled plastic is made of 80% recycled LDPE and 20% virgin LDPE (Tingstad, 2021). The next step (scenario 2) of the study, we present results that are based on direct data of the current system. The results were based on HVO and fossil trash bags, which results into 11.5 t CO2 for fossil bags and 380 kg CO2eq per year for transport and 120 kg CO2eq extra for the IoT system. The last step (scenario 3) of the study, we present results that are based on future assumptions. The results were based on using no bags and no CO2 emission from bags, which results into 120 kg CO2eq for the IoT system and 380kg CO2eq for the transport and 0 kg CO2eq for the trash bags. The future waste collection system needs to be better than the current system. That means, the future waste collection system needs to reduce the CO2eq emissions by at least 120 kg CO2eq to break-even the extra IoT system. For the IoT system to have an effect, at least 32% of the transport (km) or the number of trash bags used need to be reduced (50 bins of 160 bins), in order to outweighs the extra CO2eq from the IoT system (Figure 21). - A reduction of trp km or trash bags by 32% reduce CO2eq by 120 kg. (=IoT system). - A reduction of trp km or trash bags by 64% reduce CO2eq by 240 kg. (> IoT system).

    Life cycle assessment of IoT system inSödertälje – The case of textile waste collection and the municipality’s recycling stations2023Report (Other academic)
    Abstract [en]

    Internet of things (IoT) is expected to transform the way we live, work, and learn. Using IoT can be a game-changer for municipalities to move towards sustainability. Within the Vinnova financed project, The inclusive, sustainable, and connected society, the municipality wants to explore how IoT can enable route optimization and placement planning for increased operational efficiency. The aim of these environmental studies is to enhance the knowledge of the environmental benefits of IoT systems in three parts of the waste collection systems and services provided in the municipality of Södertälje: Waste collection in the city centre (Telge Återvinning), Textile collection (Human Bridge) and Recycling stations (Telge Återvinning). The LCA results for waste collection in the city centre are documented in Chiew & Brunklaus (2021); while the main LCA results and conclusions for textile collection (part 2) and recycling stations (part 3) are summarized in this report. The results for all three types of waste collection system show that the implementation of the IoT system is quite low (<1%). In this study, the climate impacts of both textile waste collection and recycling stations services per year were identified with LCA. By using the actor analysis, we found that in both the textile waste collection and the recycling stations services, the major climate impacts come from citizens, e.g., in the case of the textile waste collection service. The climate impact of transportation of the citizens to the textile station is 36%, followed by the plastic or paper bags from the citizens is 22% of the total impact of the textile waste, while the transportation of citizens to the recycling stations is even higher, such as 70% of the total impact of the recycling station system. The textile collection and recycling stations showed that citizen’s choice has huge impact on the CO2 emission. Re-used and recycled textiles, instead of incinerating can save up to 23-44kg CO2 per kg of new textile produced. The recycling stations collects almost 9kt of waste, which are consumer products (e.g. bicycles, furniture, electronic devices and car decks). Re-used products can save between 100kg CO2 eq per bicycle up to 300kg CO2 eq per electronic devices, such as electric tools or laptop computers, as well as 28kg CO2 eq per car decks. On the other hand, the service provided by Södertälje has a huge influence on the citizens choice. The “rullande återvinning” (rolling service), in which Telge Återvinning arranged trucks to collect bulky waste closer to the citizen can reduce the emission that is caused by the citizen transportation. In addition, the IoT system installed in the recycling station can provide good information to the citizen to avoid congestion time and paying for an empty visit due to long queue in the recycling stations. The service provided by Human Bridge and Telge Återvinning can be improved. However, both have already started to implement green choices. The environmental choices already made by Human Bridge (part 2) include the choice of thinner and recycled plastic bags and the choice of green electricity. The environmental choices already made by Telge Återvinning (part 3) include the choice of transportation (HVO instead of diesel) and the choice of green electricity. The recommendations for the future could include better service for the citizens (rolling service) and setting requirements on the service provider, such as in the textile collection (fossil-free transport).

    Carboxylated nanocellulose for wound healing applications – Increase of washing efficiency after chemical pre-treatment and stability of homogenized gels over 10 months2023In: Carbohydrate Polymers, ISSN 0144-8617, E-ISSN 1879-1344, Vol. 314, article id 120923Article in journal (Refereed)
    Abstract [en]

    To commercialize a biomedical product as a medical device, reproducibility of production and time-stability are important parameters. Studies of reproducibility are lacking in the literature. Additionally, chemical pre-treatments of wood fibres to produce highly fibrillated cellulose nanofibrils (CNF) seem to be demanding in terms of production efficiency, being a bottleneck for industrial upscaling. In this study, we evaluated the effect of pH on the dewatering time and washing steps of 2,2,6,6-Tetramethylpiperidinyloxy (TEMPO)-mediated oxidized wood fibres when applying 3.8 mmol NaClO/g cellulose. The results indicate that the method does not affect the carboxylation of the nanocelluloses, and levels of approximately 1390 μmol/g were obtained with good reproducibility. The washing time of a Low-pH sample was reduced to 1/5 of the time required for washing a Control sample. Additionally, the stability of the CNF samples was assessed over 10 months and changes were quantified, the most pronounced were the increase of potential residual fibre aggregates, reduction of viscosity and increase of carboxylic acid content. The cytotoxicity and skin irritation potential were not affected by the detected differences between the Control and Low-pH samples. Importantly, the antibacterial effect of the carboxylated CNFs against S. aureus and P. aeruginosa was confirmed. © 2023 The Authors

    Nanocelluloses – Nanotoxicology, Safety Aspects and 3D Bioprinting2022In: Advances in Experimental Medicine and Biology, ISSN 0065-2598, E-ISSN 2214-8019, Vol. 1357, p. 155-177Article in journal (Refereed)
    Abstract [en]

    Nanocelluloses have good rheological properties that facilitate the extrusion of nanocellulose gels in micro-extrusion systems. It is considered a highly relevant characteristic that makes it possible to use nanocellulose as an ink component for 3D bioprinting purposes. The nanocelluloses assessed in this book chapter include wood nanocellulose (WNC), bacterial nanocellulose (BNC), and tunicate nanocellulose (TNC), which are often assumed to be non-toxic. Depending on various chemical and mechanical processes, both cellulose nanofibrils (CNF) and cellulose nanocrystals (CNC) can be obtained from the three mentioned nanocelluloses (WNC, BNC, and TNC). Pre/post-treatment processes (chemical and mechanical) cause modifications regarding surface chemistry and nano-morphology. Hence, it is essential to understand whether physicochemical properties may affect the toxicological profile of nanocelluloses. In this book chapter, we provide an overview of nanotoxicology and safety aspects associated with nanocelluloses. Relevant regulatory requirements are considered. We also discuss hazard assessment strategies based on tiered approaches for safety testing, which can be applied in the early stages of the innovation process. Ensuring the safe development of nanocellulose-based 3D bioprinting products will enable full market use of these sustainable resources throughout their life cycle.

    Evaluation of natural resveratrol multimers as marine antifoulants2023In: Biofouling (Print), ISSN 0892-7014, E-ISSN 1029-2454Article in journal (Refereed)
    Abstract [en]

    In the current study we investigate the antifouling potential of three polyphenolic resveratrol multimers (–)-hopeaphenol, vaticanol B and vatalbinoside A, isolated from two species of Anisoptera found in the Papua New Guinean rainforest. The compounds were evaluated against the growth and settlement of eight marine microfoulers and against the settlement and metamorphosis of Amphibalanus improvisus barnacle cyprids. The two isomeric compounds (–)-hopeaphenol and vaticanol B displayed a high inhibitory potential against the cyprid larvae metamorphosis at 2.8 and 1.1 μM. (–)-Hopeaphenol was also shown to be a strong inhibitor of both microalgal and bacterial adhesion at submicromolar concentrations with low toxicity. Resveratrol displayed a lower antifouling activity compared to the multimers and had higher off target toxicity against MCR-5 fibroblasts. This study illustrates the potential of natural products as a valuable source for the discovery of novel antifouling leads with low toxicity.

    An ancestral hard-shelled sea turtle with a mosaic of soft skin and scutes2022In: Scientific Reports, E-ISSN 2045-2322, Vol. 12, no 1, article id 22655Article in journal (Refereed)
    Abstract [en]

    The transition from terrestrial to marine environments by secondarily aquatic tetrapods necessitates a suite of adaptive changes associated with life in the sea, e.g., the scaleless skin in adult individuals of the extant leatherback turtle. A partial, yet exceptionally preserved hard-shelled (Pan-Cheloniidae) sea turtle with extensive soft-tissue remains, including epidermal scutes and a virtually complete flipper outline, was recently recovered from the Eocene Fur Formation of Denmark. Examination of the fossilized limb tissue revealed an originally soft, wrinkly skin devoid of scales, together with organic residues that contain remnant eumelanin pigment and inferred epidermal transformation products. Notably, this stem cheloniid—unlike its scaly living descendants—combined scaleless limbs with a bony carapace covered in scutes. Our findings show that the adaptive transition to neritic waters by the ancestral pan-chelonioids was more complex than hitherto appreciated, and included at least one evolutionary lineage with a mosaic of integumental features not seen in any living turtle. © 2022, The Author(s).

    Preservational modes of some ichthyosaur soft tissues (Reptilia, Ichthyopterygia) from the Jurassic Posidonia Shale of Germany2023In: Palaeontology, ISSN 0031-0239, E-ISSN 1475-4983, Vol. 66, no 4, article id e12668Article in journal (Refereed)
    Abstract [en]

    Konservat-Lagerstätten, such as the Toarcian (Early Jurassic) Posidonia Shale of southwestern Germany, are renowned for their spectacular fossils. Ichthyosaur skeletons recovered from this formation are frequently associated with soft tissues; however, the preserved material ranges from three-dimensional, predominantly phosphatized structures to dark films of mainly organic matter. We examined soft-tissue residues obtained from two ichthyosaur specimens using an integrated ultrastructural and geochemical approach. Our analyses revealed that the superficially-looking ‘films’ in fact comprise sections of densely aggregated melanosome (pigment) organelles sandwiched between phosphatized layers containing fibrous microstructures. We interpret this distinct layering as representing condensed and incompletely degraded integument from both sides of the animal. When compared against previously documented ichthyosaur fossils, it becomes readily apparent that a range of preservational modes exists between presumed ‘phosphatic’ and ‘carbonized’ soft-tissue remains. Some specimens show high structural fidelity (e.g. distinct integumentary layering), while others, including the fossils examined in this study, retain few original anatomical details. This diversity of soft-tissue preservational modes among Posidonia Shale ichthyosaurs offers a unique opportunity to examine different biostratinomic, taphonomic and diagenetic variables that potentially could affect the process of fossilization. It is likely that soft-tissue preservation in the Posidonia Shale was regulated by a multitude of factors, including decay efficiency and speed of phosphatic mineral nucleation; these in turn were governed by a seafloor with sustained microbial mat activity fuelled by high organic matter input and seasonally fluctuating oxygen levels. © 2023 The Authors.

    Development Work in Swedish Eldercare: Resources for Trustworthy, Integrated Managerial Work During the COVID-19 Pandemic2022In: Frontiers In Public Health, ISSN 2296-2565, Vol. 10, article id 864272Article in journal (Refereed)
    Abstract [en]

    The extensive needs for developments of eldercare addressing working conditions, care quality, influence, and safety was highlighted during the pandemic. This mixed-method study contribute with knowledge about capability-strengthening development work and its importance for trustworthy managerial work, before and during the COVID-19 pandemic. Questionnaire data and narratives from first-line managers immediately before (n = 284) and 16 months into the pandemic (n = 189), structured interviews with development leaders (n = 25), and documents were analyzed. The results identify different focuses of development work. Strategic-level development leaders focused the strengthening of old adults' capabilities. While operational-level leaders approached strengthening employees' capability. First-line managers' rating of their trustworthy managerial work decreased during the pandemic and was associated with their workload, development support and capability-strengthening projects focusing employees' resources. The study demonstrates the gap between strategic and the operational levels regarding understanding of capability set and needed resources for strengthening capabilities and trustworthy, integrated managerial work regarding safety, influence, and quality conditions for old adults and employees.

    How Conditions and Resources Connected to Digital Management Systems and Remote Work Are Associated with Sustainable Work2022In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 19, no 23, article id 15731Article in journal (Refereed)
    Abstract [en]

    The current state of work–life transformation will see more white-collar work being performed remotely using digital management systems. There is, however, a lack of research on factors and resources contributing to sustainable work when working remotely using digital management systems. The aim of this study was to study the conditions and resources connected to digital management systems and remote work, and their associations with sustainable work, in terms of process quality, trust, and sense of coherence, when working remotely during the COVID-19 pandemic. An analytical cross-sectional study was performed. Questionnaire data from white-collar employees (n = 484) in two private companies were analyzed with regression models, focusing on the importance of the conditions and resources connected to digital management systems and remote work, stratified by working from home or at the office. The results showed digital conditions and resources being associated with indicators of sustainable work. Furthermore, the results showed that social work relations were additional important explanatory factors for sustainable remote work. This study contributes to the development of a new post-pandemic work–life balance by concluding that sustainable remote work needs to be ensured by functional digital management systems and adequate leadership supporting the development of a positive team and learning climate. © 2022 by the authors.

    The SHERLOC Calibration Target on the Mars 2020 Perseverance Rover: Design, Operations, Outreach, and Future Human Exploration Functions2022In: Space Science Reviews, ISSN 0038-6308, E-ISSN 1572-9672, Vol. 218, no 6, article id 46Article in journal (Refereed)
    Abstract [en]

    The Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) is a robotic arm-mounted instrument onboard NASA’s Perseverance rover. SHERLOC combines imaging via two cameras with both Raman and fluorescence spectroscopy to investigate geological materials at the rover’s Jezero crater field site. SHERLOC requires in situ calibration to monitor the health and performance of the instrument. These calibration data are critically important to ensure the veracity of data interpretation, especially considering the extreme martian environmental conditions where the instrument operates. The SHERLOC Calibration Target (SCT) is located at the front of the rover and is exposed to the same atmospheric conditions as the instrument. The SCT includes 10 individual targets designed to meet all instrument calibration requirements. An additional calibration target is mounted inside the instrument’s dust cover. The targets include polymers, rock, synthetic material, and optical pattern targets. Their primary function is calibration of parameters within the SHERLOC instrument so that the data can be interpreted correctly. The SCT was also designed to take advantage of opportunities for supplemental science investigations and includes targets intended for public engagement. The exposure of materials to martian atmospheric conditions allows for opportunistic science on extravehicular suit (i.e., “spacesuit”) materials. These samples will be used in an extended study to produce direct measurements of the expected service lifetimes of these materials on the martian surface, thus helping NASA facilitate human exploration of the planet. Other targets include a martian meteorite and the first geocache target to reside on another planet, both of which increase the outreach and potential of the mission to foster interest in, and enthusiasm for, planetary exploration. During the first 200 sols (martian days) of operation on Mars, the SCT has been analyzed three times and has proven to be vital in the calibration of the instrument and in assisting the SHERLOC team with interpretation of in situ data. © 2022, The Author(s).

    Environmental and resource aspects of substituting cemented carbide with polycrystalline diamond: The case of machining tools2020In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 277, article id 123577Article in journal (Refereed)
    Abstract [en]

    Synthetic diamond competes with the conventional cemented carbide (WC–Co) tool material in some applications due to its extreme hardness. However, so far, these materials have not been compared from a life cycle perspective regarding their environmental and resource impacts. The aims of this study are i) to provide detailed life cycle assessment (LCA) results for industrial polycrystalline diamond (PCD) production from diamond grit produced via high-pressure high-temperature (HPHT) synthesis and ii) to conduct the first comparative LCA of PCD and WC-Co tools for the cases of wood working and titanium alloys machining. The results show that the main hotspot in HPHT synthesis of diamond grit, which is the main precursor to PCD, is the use of WC-Co in the high-pressure apparatus. In PCD tool production, the electricity input and the use of tungsten and molybdenum contribute the most to environmental and resource impacts. The environmental and resource impacts of the PCD tool production can be reduced with 53–83% if solar electricity and full WC-Co recycling is applied. The comparison shows high environmental and resource improvements when substituting WC-Co tools with PCD tools in wood working, but not in titanium alloys machining. © 2020 The Authors

    Breast Cancer Patient-Derived Scaffolds Can Expose Unique Individual Cancer Progressing Properties of the Cancer Microenvironment Associated with Clinical Characteristics2022In: Cancers, ISSN 2072-6694, Vol. 14, no 9, article id 2172Article in journal (Refereed)
    Abstract [en]

    Breast cancer is a heterogeneous disease in terms of cellular and structural composition, and besides acquired aggressive properties in the cancer cell population, the surrounding tumor microenvironment can affect disease progression and clinical behaviours. To specifically decode the clinical relevance of the cancer promoting effects of individual tumor microenvironments, we performed a comprehensive test of 110 breast cancer samples using a recently established in vivo-like 3D cell culture platform based on patient-derived scaffolds (PDSs). Cell-free PDSs were recellularized with three breast cancer cell lines and adaptation to the different patient-based microenvironments was monitored by quantitative PCR. Substantial variability in gene expression between individual PDS cultures from different patients was observed, as well as between different cell lines. Interestingly, specific gene expression changes in the PDS cultures were significantly linked to prognostic features and clinical information from the original cancer. This link was even more pronounced when ERα-status of cell lines and PDSs matched. The results support that PDSs cultures, including a cancer cell line of relevant origin, can monitor the activity of the tumor microenvironment and reveal unique information about the malignancy-inducing properties of the individual cancer niche and serve as a future complementary diagnostic tool for breast cancer. © 2022 by the authors.

    Alginate and nanocellulose dressings with extract from salmon roe reduce inflammation and accelerate healing of porcine burn wounds.2023In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488Article in journal (Refereed)
    Abstract [en]

    Partial thickness thermal burn wounds are characterized by prolonged inflammatory response, oxidative stress, tissue damage, and secondary necrosis. An optimal dressing for burn wounds would reduce inflammation and oxidative stress while providing a moist, absorbent, and protective cover. We have developed an extract from unfertilized salmon roe containing components with potential anti-inflammatory and antioxidative properties, called HTX. HTX has been combined with alginate from brown algae and nanocellulose from tunicates, and 3D printed into a solid hydrogel wound dressing called Collex. Here, Collex was tested on partial thickness burn wounds in Göttingen minipigs compared to Jelonet, and a variant of Collex without HTX. We found that dermal treatment of burn wounds with Collex resulted in accelerated healing at a majority of measured points over 23 days, compared to treatment with Jelonet. In comparison to Collex without HTX, Collex enhanced healing in the first week after trauma where wound progression was pronounced. Notably, Collex reduced the inflammatory response in the early post-injury phase. The anti-inflammatory response of Collex was investigated in more detail on activated M1 macrophages. We found that Collex, as well as HTX alone, significantly reduced secretion of pro-inflammatory interleukin-1β as well as intracellular levels of oxidative stress. The results from this study indicate that Collex is a potent dressing for treatment of burn wounds, with the anti-inflammatory effect of HTX beneficial in the initial phase, and the moist qualities of the hydrogel favorable both in the initial and the proceeding proliferative phase of wound healing.

    Barriers to value specification when carrying out digitalization projects2021In: Technology Innovation Management Review, E-ISSN 1927-0321, Vol. 11, no 5, p. 54-64Article in journal (Refereed)
    Abstract [en]

    If digitalization projects aim to effectively create value for a company, one precondition is having a shared view among company staff and project members of what the "desirable" value is. However, it has been shown that few companies fully understand the value that digitalization projects can create for them, while many companies still launch digitalization projects without this understanding. This contributes to the current "alarmingly" low success rate for digitalization projects. Development of effective methods to specify the desired values of digitalization projects is thus important. One step in developing improved specification methods is to ask what the possible barriers are to improving current value specification practices. The purpose of the current study is to address this. We analyzed several digitalization projects regarding how specifications of desired project value were carried out, finding that very limited resources are spent on specifying desired values in digitalization projects, and that this limits project success. Likewise, there are several barriers to increasing resources for specifying desired values. Our findings contribute to understanding the development of value specification methods that aim to overcome these barriers and thus could help improve the success rate of digitalization projects.

    How to Deal with Differing Views of Resource Efficiency when Carrying out Digitalization Projects2020In: Advances in Transdisciplinary Engineering, ISSN 2352-751X, Vol. 13, p. 71-82Article in journal (Refereed)
    Abstract [en]

    Having project goals that are shared among project members are preconditions for resource efficient as well effective projects and operations. However, specifying and communicating project goals require an ability to identify goals that are indeed commonly shared. Rapid technological developments may require digitalization projects that lead to large portions of existing company staff being redundant, making it possible to assume that the quest of finding a commonly shared view of what is resource-efficient' will be increasingly challenging. Development of methods to specify project goals that are incentivizing for all project members and staff can hence be assumed to be important. One step in developing improved specification methods is to ask how the process to specify desired value from digitalization projects handles possible disagreements of what is desired value'. The purpose of this study was to answer this question. We analyzed several digitalization projects, and how specifications of desired project results impacted project outcomes. We found that potential disagreements regarding desirable project outcomes generally are avoided by avoiding specification of what a desirable resource efficiency outcome is, and how actual project outcomes should be measured. However, we also found that this practice also led to unsatisfying project outcomes regarding resource-efficiency improvements, and that improved methods to specify desired value from digitalization projects should be developed. Our findings support earlier findings that the general failure rate of digitalization projects is high, often due to insufficient specification of desired projects outcomes before the projects are initiated. Our findings contribute to the understanding that despite this, there are also perceived benefits of spending limited resources on specification of desired outcomes. If attempts to improve the success rate of digitalization projects by improving specifications of desired project outcomes is to succeed, these perceived benefits must be considered. © 2020 The authors

    Nanostructured micro particles as a low-cost and sustainable catalyst in the recycling of PET fiber waste by the glycolysis method2021In: Waste Management, ISSN 0956-053X, E-ISSN 1879-2456, Vol. 126, p. 559-566Article in journal (Refereed)
    Abstract [en]

    Magnetic Mg-Al-O@Fe3O4 micro particles were synthesized by coating nanosized Mg-Al double oxides onto Fe3O4 micro particles. The formed hierarchical structure gave Mg-Al-O@Fe3O4 micro particles a high active surface area, which enabled these micro particles to work efficiently as a catalyst in the glycolysis of poly(ethylene terephthalate) (PET). The bis(hydroxyethyl) terephthalate (BHET) yield reached above 80 mol% in the presence of 0.5 wt% of Mg-Al-O@Fe3O4 micro catalyst in the reaction system within 90 min at 240 °C. After the reaction, Mg-Al-O@Fe3O4 micro catalyst was easily retrieved by a magnetic decantation and can be repetitively used for two times with a high catalytic efficiency. After that, the deactivated Mg-Al-O@Fe3O4 micro catalyst can be regenerated by heat treatment. The regenerated Mg-Al-O@Fe3O4 micro catalyst displays a comparable catalytic performance as that of the virgin catalyst. In addition, the Mg-Al double oxides and Fe3O4 micro particles are low-cost and environmentally benign. Therefore, the Mg-Al-O@Fe3O4 micro catalyst may contribute to an economically and environmentally improved large-scale circular recycling of PET fiber waste. © 2021 The Author(s)

    Life cycle assessment of textile fibre-to-fibre recycling by cellulose carbamate technology2023In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 426, article id 139189Article in journal (Refereed)
    Abstract [en]

    The fashion industry faces major challenges in reducing its environmental impacts along the textile value chain, from fibre production, via various processing steps, use phase and to the end-of-life stage. A major challenge is how to shift from the current linear industry to a circular one, where textiles are both sustainably produced, and after the full life length, recycled into new fibres with high value applications. The aim of this study was to evaluate the environmental impacts of post-consumer textile fibre-to-fibre recycling by cellulose carbamate technology, in terms of climate impact, water scarcity impact, cumulative energy demand and land use impact. By performing life cycle assessment, it was shown that the chemically recycled cellulose carbamate fibre has a climate impact of about 2.2 kg CO2-eq per kg fibre, water scarcity impact of 1.6 m3 H2O-eq per kg fibre, cumulative energy demand of 90 MJ-eq per kg fibre and land use impact of about 92 Pt per kg fibre (when applying mass allocation of co-products). Hotspots identified during the fibre production technology were electricity use and production of sodium hydroxide. In a sensitivity analysis, it was shown that the choice of electricity has a major influence on the results, and by using a renewable electricity mix over an average Finnish electricity mix, the impact could be decreased for all impact categories, except when using bioenergy, which would increase the land use impact. Compared to primary fibres like viscose and conventional cotton, these impacts are in the lower to middle range, showing potential to lower environmental impacts when moving towards an increased amounts of recycled post-consumer textile fibre with high value applications, that can replace primary fibres.

    A Start-up Firm´s Greenfield Project of Building a New State-of-the-art Factory in Sweden2020Report (Other academic)
    Abstract [en]

    A unique greenfield project within a new industrial domain in Europe started 2017, with a mission to build the world’s greenest batteries, to enable and accelerate the European transition to renewable energy. The new firm, together with Sweden’s Innovation Agency Vinnova, initiated collaboration in the project “Research – new state-of-the-art factory”, (VDr. 2017-03397). This report includes an executive summary and an extract of results. The research project specifically contributed to the initiation and knowledge related to the union collaboration process, aiming to support the establishment of a new state-of-the-art factory in a Swedish context. Relevant results identified during the start-up journey will serve as a contextual base and be used in agreement with the start-up firm in planned publications, i.e. they are not included in detail in this report. Furthermore, areas of development regarding concepts for work organization in the initial production organization have been identified, and initiated actions during the study contributing to operational work processes, and organizational learning.

    Designing for sustainable work during industrial startups—the case of a high-growth entrepreneurial firm2021In: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913, Vol. 52, no 7, p. 807-Article in journal (Refereed)
    Abstract [en]

    New firms face challenges regarding pace, time, scalability, and societal changes, requiring increased attention to sustainable work prerequisites. However, this dimension of social sustainability is less studied than economic and ecological sustainability. This paper addresses how sustainable work is considered in an entrepreneurial startup carrying out a greenfield project within a new industrial domain. Data were collected for 30 months in a longitudinal case study. The study shows that (i) working condition challenges were drivers for innovative solution-oriented approaches with potential for rapid decision-making, flexibility, and to attract, recruit, retain, and develop talented people; (ii) a strategic focus on sustainability and collective contribution to a purpose-driven vision were important enablers for taking steps of operationalising sustainable work dimensions during the startup; and (iii) the firm’s early stakeholder collaboration addressing working conditions was an important means for design for sustainable work and their role as agents of sustainable work. Research implications are how sustainable work can be considered during startups and through stakeholder collaboration. Furthermore, the case contributes to increased knowledge of how the three pillars of sustainability—economic, ecological, and social sustainability—are interrelated and are suggested to be continuously considered over time, specifically during rapid major changes.

    Stakeholder collaboration inspired by the Nordic model – Towards sustainable work and competitiveness during an industrial startup2021In: European Journal of Workplace Innovation, ISSN 2387-4570, Vol. 6, no 1-2, p. 198-219Article in journal (Refereed)
    Abstract [en]

    External stakeholder collaboration is vital for new industrial projects and establishments. The aim of this paper is to explore why and how new firms can create relations and stakeholder collaboration with trade unions during industrial start-ups. A case study was carried out in the early phases of a new firm´s major greenfield project aimed at establishing a new industrial domain in a Nordic context. The results showed that early co-operation between a new firm and trade unions has the potential to proactively address prerequisites for sustainable work in design phases of new factories, but also to strengthen the attention to other dimensions of social sustainability that are crucial for an industrial start-up’s longterm possibilities for success. However, specifically in a rapidly growing new firm, there needs to be a systematic approach that incorporates continuous anchoring activities both within and between the stakeholders. Practical implications are how new firms can initiate and establish co-operation with trade unions and other social partners in fast-moving work environments and change processes. Hence, the study identifies advantages and approaches for new firms to build relations  with trade unions in a stakeholder collaboration chain inspired by the Nordic model. Further, to proactively pay attention to dimensions of social sustainability in a new firm´s early development phases and change processes, such as industrial start-ups, seems beneficial from an individual, business, and a societal perspective.

    Dialogverktyget Work Balance i praktiken: En lärande utvärdering för hållbart arbete2022Report (Other academic)
    Abstract [en]

    För att svara upp mot utmaningarna inom det organisatoriska och sociala arbetsmiljöområdet och främja ett hållbart arbetsliv har Scania utvecklat dialogverktyget Work Balance. Det är forskningsbaserat och avser ge stöd och struktur åt chefer att föra djupare och regelbunden dialog med medarbetare kring upplevelser av arbetssituationer. Dialogen är strukturerad inom de fyra ämnesområdena Hanterbarhet, Begriplighet, Meningsfullhet och Återhämtning, och avses användas på frivillig basis i grupp eller individuellt. HELIX har i samarbete med Scania genomfört en lärande utvärdering av Work Balance. Syftet med denna utvärdering var att identifiera möjliggörare och hinder för användningen av Work Balance samt att ta fram förbättringsförslag som underlag för Scanias vidareutveckling av dialogverktyget. HELIX-forskare intervjuade 44 medarbetare, första och andra linjens chefer ur produktions- och kontorsmiljö, från sex produktionsenheter i fyra länder. Dessa använde eller hade valt att inte använda dialogverktyget. Resultaten visar en över lag positiv syn på Work Balance, på frivilligheten i användningen, relevansen, anpassningsbarheten, flexibiliteten och det varierade användningssättet. Men vid en produktionsenhet där verktyget inte fungerat som önskat har användningen avbrutits. Implementeringen varierade avseende tydlighet i information och träning i verktyget. Användningsförutsättningarna varierade kraftigt beroende på tidigare erfarenheter, kultur och mognad hos team och chefer att vara öppna och sätta ord på känslor. Användningen varierade även mellan produktionsenheter. Vid regelbunden användning var man mycket nöjd, men andra som inte sett nyttan hade slutat använda Work Balance. I produktion var teamen större, tiden mer begränsad, språk och frågor kändes mer abstrakta och användningen upplevdes svårare än i kontor. Högre chefers efterfrågan av användning tenderade ge en mer uthållig användning. Upplevda effekter var; öppnare klimat, bättre kommunikation, ökat samförstånd och tidigare identifiering av problem. Många trodde på en indirekt positiv koppling mellan Work Balance och nyckeltal. En enklare version av Work Balance efterfrågades, men också bättre hantering av identifierade problem, där mer stöd och utbildning till chefer och team behövs. En väl utvecklad förbättringskultur torde vara en bra grund för en utvecklad dialog där Work Balance kopplas till andra verktyg eller metoder som används i teamets kärnprocesser.

    The dialogue tool Work Balance in practice : A learning evaluation for sustainable work2022Report (Other academic)
    Abstract [en]

    In order to respond to the challenges in the organisational and social work environment area and to promote a sustainable working life, Scania has developed the dialogue tool called Work Balance (WB) It is research-based and intended to provide support and structure for managers to maintain an in-depth and regular dialogue with employees about their experiences of work situations. The dialogue is structured using four elements – Manageability, Comprehensibility, Meaningfulness and Recovery – and is intended to be used on a voluntary basis in groups or individually. In cooperation with Scania, HELIX has conducted a learning evaluation for Work Balance. The purpose of this learning evaluation was to identify enablers and obstacles to the use of Work Balance and to produce improvement proposals as a basis for Scania’s further development of the dialogue tool. HELIX researchers interviewed 44 employees, first- and second-line managers from production and office environments, from six production units in four countries. These employees used or had chosen not to use the dialogue tool. The results show an overall positive view of Work Balance, of the voluntary use, relevance, adaptability, flexibility and the varied mode of application. However, its use has been discontinued at one production unit where the tool did not work as desired. The implementation varied in terms of clarity of information and training in the tool. The conditions of use varied greatly depending on previous experience, culture and maturity of teams and managers in terms of being open and putting feelings into words. Use also varied between production units. Those who used it regularly were very satisfied, while others who did not see the benefit stopped using Work Balance. In production, the teams were larger, time was more limited, language and questions felt more abstract, and use was perceived as more difficult than in an office environment. Senior managers requesting that it be used tended to result in more sustained use. Perceived effects were: a more open atmosphere, better communication, increased consensus and earlier identification of problems. Many believed in an indirect positive link between Work Balance and key performance indicators. A simpler version of Work Balance was requested, but also better handling of identified problems, where more support and training for managers and teams are needed. A well-developed culture of improvement should be a good basis for a developed dialogue where Work Balance is linked to other tools or methods used in the team’s core processes.

    An Examination of Soil Crusts on the Floor of Jezero Crater, Mars2023In: Journal of Geophysical Research: PlanetsArticle in journal (Refereed)
    Abstract [en]

    Martian soils are critically important for understanding the history of Mars, past potentially habitable environments, returned samples, and future human exploration. This paper examines soil crusts on the floor of Jezero crater encountered during initial phases of the Mars 2020 mission. Soil surface crusts have been observed on Mars at other locations, starting with the two Viking Lander missions. Rover observations show that soil crusts are also common across the floor of Jezero crater, revealed in 45 of 101 locations where rover wheels disturbed the soil surface, 2 out of 7 helicopter flights that crossed the wheel tracks, and 4 of 8 abrasion/drilling sites. Most soils measured by the SuperCam laser-induced breakdown spectroscopy (LIBS) instrument show high hydrogen content at the surface, and fine-grained soils also show a visible/near infrared (VISIR) 1.9 µm H2O absorption feature. The Planetary Instrument for X-ray Lithochemistry (PIXL) and SuperCam observations suggest the presence of salts at the surface of rocks and soils. The correlation of S and Cl contents with H contents in SuperCam LIBS measurements suggests that the salts present are likely hydrated. On the “Naltsos” target, magnesium and sulfur are correlated in PIXL measurements, and Mg is tightly correlated with H at the SuperCam points, suggesting hydrated Mg-sulfates. Mars Environmental Dynamics Analyzer (MEDA) observations indicate possible frost events and potential changes in the hydration of Mg-sulfate salts. Jezero crater soil crusts may therefore form by salts that are hydrated by changes in relative humidity and frost events, cementing the soil surface together.

    Operator Contributions to Innovation: Supporting Innovative Production Development in a Digital Learning Environment2022In: Advances in Transdisciplinary Engineering, IOS Press BV , 2022, Vol. 21, p. 580-591Conference paper (Refereed)
    Abstract [en]

    As all technologies come to pass, change by innovation is needed both ways, exploiting current knowledge to do better and exploring new knowledge to do differently. Due to years of continuous improvement (CI), exploitation of current knowledge in production development is rather well investigated, exploration is less. It could be argued that not utilizing the potential explorative operator contributions to production innovation is a lost opportunity to increase a company's innovation capability. Simultaneously, operators are facing great changes when manufacturing is adopting to digitalization and sustainability challenges enhancing the need for production innovation. This study focused on a team of operators through a workshop series of five sessions about explorative activities in a format using structured and semi-structured interviews. The study provided a basis for constructing a model for positioning operators' both digital and explorative maturity level. Through the empirical data and the model, the conclusion is illustrated as alternative pathways to reach a desired level of operator maturity. It was concluded that approaching digital and explorative maturity for operators should be done as a two-step process. Increasing both maturities simultaneously, as with the studied team, showed difficult due to the digital and explorative maturity being co-dependent. The suggested two-step process contributes to a better understanding of prerequisites and opportunities for operators to participate and contribute to production innovation in digitalized work environments, ultimately increasing the company's innovation capability. © 2022 The authors

    Preservation and Taphonomy of Fossil Insects from the Earliest Eocene of Denmark2022In: Biology, E-ISSN 2079-7737, Vol. 11, no 3, article id 395Article in journal (Refereed)
    Abstract [en]

    Marine sediments of the lowermost Eocene Stolleklint Clay and Fur Formation of north-western Denmark have yielded abundant well-preserved insects. However, despite a long history of research, in-depth information pertaining to preservational modes and taphonomic pathways of these exceptional animal fossils remains scarce. In this paper, we use a combination of scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDX), transmission electron microscopy (TEM) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) to assess the ultrastructural and molecular composition of three insect fossils: a wasp (Hymenoptera), a damselfly (Odonata) and a pair of beetle elytra (Coleoptera). Our analyses show that all specimens are preserved as organic remnants that originate from the exoskeleton, with the elytra displaying a greater level of morphological fidelity than the other fossils. TEM analysis of the elytra revealed minute features, including a multilayered epicuticle comparable to those nanostructures that generate metallic colors in modern insects. Additionally, ToF-SIMS analyses provided spectral evidence for chemical residues of the pigment eumelanin as part of the cuticular remains. To the best of our knowledge, this is the first occasion where both structural colors and chemical traces of an endogenous pigment have been documented in a single fossil specimen. Overall, our results provide novel insights into the nature of insect body fossils and additionally shed light on exceptionally preserved terrestrial insect faunas found in marine paleoenvironments. © 2022 by the authors.

    Crypsis in the pelagic realm: evidence from exceptionally preserved fossil fish larvae from the Eocene Stolleklint Clay of Denmark2021In: Palaeontology, ISSN 0031-0239, E-ISSN 1475-4983, Vol. 64, no 6, p. 805-815Article in journal (Refereed)
    Abstract [en]

    Marine deposits of earliest Eocene age in northern Jutland, Denmark, are renowned for yielding diverse teleost assemblages that have proved central for enhancing our understanding of the early evolution of many extant actinopterygian clades. In this study, we investigate diminutive larval fish fossils from the Stolleklint Clay, Ølst Formation, that retain multiple soft-tissue features preserved as distinct dark-coloured stains. To examine the elemental and molecular composition of these soft parts, we employed a combination of time-of-flight secondary ion mass spectrometry (ToF-SIMS), scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS). Our analyses revealed that the preserved structures contain chemically identifiable eumelanin intimately associated with densely aggregated microbodies that are morphologically consistent with melanosome organelles. Thus, we conclude that the carbonaceous structures represent traces of originally melanized body parts, including the eyes and peritoneum. Comparable pigmentation patterns are seen in many extant teleost larvae that use semi-transparency as a means of camouflage in pelagic environments, to suggest a similar visual appearance of the Stolleklint Clay fish fossils. This in turn suggests that adaptations for concealment and UV-protection had already evolved by the beginning of the Eocene, notably during a time interval characterized by an extreme greenhouse climate, when the global fish fauna become increasingly modern in composition. © 2021 The Authors.
