Making packaging more sustainable: Effects of resource embeddedness
- 2023
-
Licentiate thesis (other academic/artistic)abstract
- Firms involved in e-commerce distribution are faced with challenges due to the increasing volume of single shipments to consumers, including concerns regarding sustainability. For instance, the role of packaging has gained increased attention because of over-packed parcels and excessive air within those parcels, which frustrate retailers, logistics service providers, and consumers. E-commerce also challenges established structures for distribution to physical stores, when firms increasingly use multiple distribution channels to reach consumers. The design of e-commerce packaging affects other resources in retail distribution, and vice versa. In turn, such interdependence not only affects how packaging solutions can be developed but also highlights the importance of various firms developing resources in interaction. This thesis aims to explore how more sustainable packaging solutions are developed in a business network context. A single case study was conducted to examine how e-commerce packaging interacts with other resources and how this interaction affects various firms in their efforts to create more sustainable packaging solutions. In doing so, the thesis is theoretically grounded in the Industrial Network Approach and focuses on resource interaction and how a focal resource—e-commerce packaging—is embedded in a business network. The thesis contributes by highlighting the challenges involved in efforts to make individual resources more sustainable in various parts of a business network. The findings underscore the importance of identifying how resources are embedded in network settings. Regarding e-commerce packaging, three network settings are identified: product development, sorting, and packing. The implications for firms involved in these network settings are that interaction is required both within and across the network settings to develop more sustainable packaging solutions.

HMI tests in simulator
- 2007
-
Reports (other academic/artistic)abstract
- The main goal of SASPENCE is to develop and evaluate an innovative system able to perform the Safe Speed and Safe Distance concept, that means to help the driver in avoiding accident situations related to excessive speed or too small headway. So, the system should co-operate seamlessly with the driver, suggesting the proper velocity for the given condition (road structure, traffic situation, etc.) preventing risky and dangerous situations and thus avoiding collision. This support is done through a Human Machine Interface (HMI). It is essential that the HMIs are easily understandable by the driver and that they induce a suitable reaction to the danger, otherwise the system is worthless. The simulator tests are the second step of the HMI design process that counts three of them. After the static tests that have enabled to show up the preferred visual, haptic and acoustic HMI, 8 combinations of HMI have been tested in dynamic conditions in the PSA driving simulator while part of the SASPENCE modules were running and tested. These tests should enable us to understand which HMIs are the best for the driver, that is to say, which HMI makes it possible to give the SASPENCE information in the clearest way to the driver. The main aims of these tests were to evaluate the effects of the SASPENCE system on drivers’ behaviour and to give recommendations for the HMI to be installed in the two test-cars, according to drivers’ preference and the efficiency of the HMI. They were also useful: - to improve the representativeness of the static tests results, - to check the good operation of some modules, that will be implemented in the test cars, and to check the good communication between the driver and the HMI, very early in the project, long before the demonstration cars are ready, - to complete the final road tests by measurements and observations in a more reproducible and observable conditions than the real road test. One interesting result of these tests is that the HMIs that were selected at the end of the static tests appeared to be too complex to be understood when one was driving. Another main result is that the SASPENCE system is efficient, as drivers spend less time in risky situations when driving with the SASPENCE system.

Symmetric solutions of evolutionary partial differential equations
- 2017
-
In: Nonlinearity. - : IOP PUBLISHING LTD. - 0951-7715 .- 1361-6544. ; 30:10, s. 3932-3950
-
Journal article (peer-reviewed)abstract
- We show that for a large class of evolutionary nonlinear and nonlocal partial differential equations, symmetry of solutions implies very restrictive properties of the solutions and symmetry axes. These restrictions are formulated in terms of three principles, based on the structure of the equations. The first principle covers equations that allow for steady solutions and shows that any spatially symmetric solution is in fact steady with a speed determined by the motion of the axis of symmetry at the initial time. The second principle includes equations that admit breathers and steady waves, and therefore is less strong: it holds that the axes of symmetry are constant in time. The last principle is a mixed case, when the equation contains terms of the kind from both earlier principles, and there may be different outcomes; for a class of such equations one obtains that a spatially symmetric solution must be constant in both time and space. We list and give examples of more than 30 well-known equations and systems in one and several dimensions satisfying these principles; corresponding results for weak formulations of these equations may be attained using the same techniques. Our investigation is a generalisation of a local and one-dimensional version of the first principle from EhrnstrOm et al (2009 Int. Math. Res. Not. 2009 4578-96) to nonlocal equations, systems and higher dimensions, as well as a study of the standing and mixed cases.

Thermocapillary thin films : periodic steady states and film rupture
- 2024
-
In: Nonlinearity. - 0951-7715. ; 37:4
-
Journal article (peer-reviewed)abstract
- We study stationary, periodic solutions to the thermocapillary thin-film model ∂ t h + ∂ x h 3 ∂ x 3 h − g ∂ x h + M h 2 1 + h 2 ∂ x h = 0 , t > 0 , x ∈ R , which can be derived from the Bénard-Marangoni problem via a lubrication approximation. When the Marangoni number M increases beyond a critical value M ∗ , the constant solution becomes spectrally unstable via a (conserved) long-wave instability and periodic stationary solutions bifurcate. For a fixed period, we find that these solutions lie on a global bifurcation curve of stationary, periodic solutions with a fixed wave number and mass. Furthermore, we show that the stationary periodic solutions on the global bifurcation branch converge to a weak stationary periodic solution which exhibits film rupture. The proofs rely on a Hamiltonian formulation of the stationary problem and the use of analytic global bifurcation theory. Finally, we show the instability of the bifurcating solutions close to the bifurcation point and give a formal derivation of the amplitude equation governing the dynamics close to the onset of instability.

Conference paper (peer-reviewed)abstract
- Defect distributions have been documented by optical metallography, scanning electron microscopy and electron backscatter diffraction in alloy 152 and 52 mockups welds, alloy 52 and 52M overlay mockups and an alloy 52M inlay. Primary defects were small cracks at grain boundaries except for more extensive cracking in the dilution zone of an alloy 52 overlay on 304SS. Detailed characterizations of the dilution zone cracks were performed by analytical transmission electron microscopy identifying grain boundary titanium-nitride precipitation associated with the intergranular separations.

Hepatitis C virus enters liver cells using the CD81 receptor complex proteins calpain-5 and CBLB
- 2018

In: PLoS Pathogens. - : Public Library of Science (PLoS). - 1553-7366 .- 1553-7374. ; 14:7

Journal article (peer-reviewed)abstract
- Hepatitis C virus (HCV) and the malaria parasite Plasmodium use the membrane protein CD81 to invade human liver cells. Here we mapped 33 host protein interactions of CD81 in primary human liver and hepatoma cells using high-resolution quantitative proteomics. In the CD81 protein network, we identified five proteins which are HCV entry factors or facilitators including epidermal growth factor receptor (EGFR). Notably, we discovered calpain-5 (CAPN5) and the ubiquitin ligase Casitas B-lineage lymphoma proto-oncogene B (CBLB) to form a complex with CD81 and support HCV entry. CAPN5 and CBLB were required for a post-binding and pre-replication step in the HCV life cycle. Knockout of CAPN5 and CBLB reduced susceptibility to all tested HCV genotypes, but not to other enveloped viruses such as vesicular stomatitis virus and human coronavirus. Furthermore, Plasmodium sporozoites relied on a distinct set of CD81 interaction partners for liver cell entry. Our findings reveal a comprehensive CD81 network in human liver cells and show that HCV and Plasmodium highjack selective CD81 interactions, including CAPN5 and CBLB for HCV, to invade cells.

Historical thinking in a digital environment : Swedish history teaching analysed through a TPACK lens
- 2023
-
In: Clio. History and History Teaching. - Valencia : Universidad de Zaragoza. - 1139-6237. ; :49, s. 57-71
-
Journal article (peer-reviewed)abstract
- This paper presents results from a large-scale study of history teachers in Swedish secondary schools. The study examines perceptions of history, content being taught, teaching methods and use of digital technology. The study uses the Technological Pedagogical and Content Knowledge (TPACK) framework to analyse the results together with narrative theory.The main results indicate that knowledge of the past and contemporary perspectives from a canonical tradition are prioritised, together with a content-based lecture-style pedagogy. The use of digital technology does not seem to challenge methods or bring new perspectives to history teaching. However, to fully understand history teaching with technology, a framework that emphasises all parts of history education is needed. This calls for further development of the TPACK model, which is further discussed in this article.

Conference paper (other academic/artistic)abstract
- Historieundervisning i en digital samtid: Innehåll, kontexter och verktyg – Presentation av resultat från pågående forskning Den omfattande digitaliseringen av svensk skola är en del av global process. Skolans digitalisering har i stor utsträckning genomförts ovanifrån och ambitionerna har varit stora. Införandet av digital teknik sägs ge möjligheter till ökad delaktighet, motivation och nya perspektiv i undervisningen. Digitaliseringen är i stor utsträckning en ideologisk och ekonomisk företeelse, snarare än en epistemologisk och kunskaperna om digitalisering i relation till historieundervisning är mycket begränsade. Det är därför av vikt att undersöka vilka konsekvenserna den pågående digitaliseringen får. Avhandlingens huvudsakliga syfte är att historieundervisningen på grundskolans högstadium och fokus ligger på att beskriva vilka olika former och innehåll undervisningen tar i ett digitaliserat klassrum. Genom detta blir frågor om narrativitet, historiekultur och historiemedvetande relevanta att sätta i relation till den undervisning som bedrivs. Parallellt med historiedidaktiska frågor blir också den digitala tekniksens specifika möjligheter att bidra till en förändrad historieundervisning relevant. Avhandlingen tar sin utgångspunkt i det teoretiska ramverk som benämns som TPACK och som är en välspridd modell för att förstå teknik i relation till undervisning. I avhandlingen kommer denna modell bearbetas för att bättre kunna fungera som ett stöd att analysera lärares yrkespraktik. Under höstterminen 2023 genomfördes avhandlingens första delstudie. Detta var en kvantitativ enkätstudie där totalt 540 lärare från hela landet deltog. Presentationen avser att presentera några preliminära resultat från denna delstudie i relation till ett pågående arbete med utveckling av en teoretisk modell för att förstå historieundervisning i en digital skola.
