Solid oxide fuel cells (SOFCs) produce electricity with high electrical efficiency and fuel flexibility without pollution, for example, CO2, NOx, SOx, and particles. Still, numerous issues hindered the large-scale commercialization of fuel cell at a large scale, such as fuel storage, mechanical failure, catalytic degradation, electrode poisoning from fuel and air, for example, lifetime in relation

Motivated by the previously documented discrepancy between actual and predicted power, the present paper provides new tools for analyzing the local asymptotic power of panel unit root tests. These tools are appropriate in general when considering panel data with a dominant autoregressive root of the form ρi = 1 + ciN−κT−τ, where i = 1, ..., N indexes the cross-sectional units, T is the number of t

1. Net primary production (NPP) by terrestrial ecosystems appears to be proportional to absorbed photosynthetically active radiation (APAR) on a seasonal and annual basis. This observation has been used in 'diagnostic' models that estimate NPP from remotely sensed vegetation indices. In 'prognostic' process-based models carbon fluxes are more commonly integrated with respect to leaf area index ass

Upon locating a suitable dung pile, ball-rolling dung beetles shape a piece of dung into a ball and roll it away in a straight line. This guarantees that they will not return to the dung pile, where they risk having their ball stolen by other beetles. Dung beetles are known to use celestial compass cues such as the sun, the moon and the pattern of polarised light formed around these light sources

Purpose – Despite a growing interest in both women and university academic entrepreneurship, there are very few studies addressing women's academic entrepreneurship. The authors address this gap by focusing on university incubators for women's academic entrepreneurship. The purpose of this paper is to examine and analyze the significance of university incubators for the promotion and development o

The polycondensation of polyesters from C-12 monomers at 95 degrees C in aqueous o/w emulsions, stabilized by acidic surfactants, has been studied in detail with a range of methods during the course of the reaction, resulting in a better understanding of the underlying reaction mechanisms. Comparisons of different surfactants, and effects of added NaCl, demonstrate that the reaction site is locate

Den svenska rättegångsbalken bygger på den kontradiktoriska principen. Balken innehåller en rad regler som ger en misstänkt brottsförövare rättigheter inom straffprocessen, exempelvis är rätten till insyn och påverkan av central betydelse. Att få insyn i förundersökningen innebär en rätt att få tillgång till material som rör brottsutredningen. Möjligheten till påverkan i processen innefattar blandThe Swedish Code of Judicial Procedure is based on the adversarial principle. The Code contains a number of rules concerning the suspect’s rights in the criminal process, such as the right to insight and influence in the criminal investigation. Gaining insight into the investigation involves a right of access to the information of the investigation. The right to influence the process includes a ri

Issues: The company and its business environment have gone through big changes during the company’s existence. With big internal changes, such as shutdown of own

Trots att den psykiska ohälsan ökar, upplevs det fortfarande som stigmatiserande. En vanlig orsak till detta är okunskap. I forskning har det framkommit att människor erhåller mycket av sin kunskap genom filmer, varvid den framställning som görs i film påverkar den förståelse och de attityder som omgivning kommer ha till psykisk ohälsa. En film där psykisk ohälsa är central är “A star is born” fråAlthough mental illness is an increasing problem, it’s still stigmatizing. A reason for this is a lack of knowledge. Research has shown that people obtain much of their knowledge through films, whereby the presentation made in movies affects the understanding and the attitudes that the environment will have to mental illness. A film where mental illness is central is "A star is born" fro

This study examines the process of gentrification. In so doing, the main aim is to explore a context wherein the process of gentrification is deemed unconventional. The context deemed unconventional is the one beyond the city, more accurately a coastal hamlet called Brantevik, located in the municipality of Simrishamn, in the southeastern part of the Scania region. By investigating whether Brantev

Instead of investing 145 billion SEK in building a new high speed rail network, much greater value in terms of transport capacity is likely to be found in constructing a new system of tube transport with a travel speed of 600 km/h. The suggested technology does not exist yet. However, research and development is advancing and accepting that a new technology is emerging might be the greatest hurdle

The objective of this study is to obtain knowledge about the important factors that affect people when evacuating by elevator from underground stations. The objective is also to contribute for future development of recommendations and research in the field. The study was carried out in the form of a questionnaire survey in Stockholm. Two groups were selected, the first consisting of randomly selec

Retro game collecting An ethnological study of the creation of an identity by people who collect older video and computer games The purpose of this ethnological thesis is to examine and analyse how the meaning of the informants' retro video game collections is created, what is considered valuable in the retro game collecting community and how this community affects the informants’ creation of

Syftet med uppsatsen är att undersöka hur avtalsmekanismen I AvtL påverkas av den ökande digitaliseringen i samhället. Uppsatsen avser även att undersöka hur den ökade användningen av AI, som på vissa sätt har en nära koppling till digitaliseringen, påverkar avtalsmekanismen. AvtL har länge kritiserats för att vara gammal och ineffektiv men på senare år har mer positiva ståndpunkter yttrats. UppsaThe purpose of this study is to investigate the ways that the Swedish Contracts Act on the formation of contracts is affected by the increasing digitalization in our society. The study also aims to investigate how the increased use of AI, which in some ways is closely correlated to digitalization, effects the formation on contracts. The Swedish Contracts Act has long been critiqued for being old a

Utgångspunkten i svensk avtalsrätt är att rättsverkningar förutsätter aktiva handlingar. Avtal anses normalt uppkomma genom ett utbyte av samstämmiga viljeförklaringar i form av anbud och accept. Passivitet, dvs. underlåtenhet att handla, leder som huvudregel inte till avtalsbundenhet. Denna ordning vilar på avtalsfriheten och viljeprincipen, enligt vilken en part endast blir bunden till vad denneThe starting point in Swedish contract law is that legal effects require active actions. Contracts are normally considered to arise through an exchange of mutual declarations of intent in the form of an offer and acceptance. Passivity, i.e. failure to act, does not, as a general rule, lead to contractual obligations. This arrangement is based on freedom of contract and the principle of intent, acc

This study focuses on children’s participation in child welfare investigations. Interviews were conducted with four child welfare caseworkers from the social services to understand how they view children’s participation and how they work to support it. The study aims to gain a better understanding of how caseworkers see children being involved, and what factors make it easier or more difficult for

Urbanization is driving cities to grow, often through urban densification. Utilising computer-based simulations executed over 3D representations of the city is imperative in addressing the challenges posed by implementing sustainable urban densifications; like ensuring adequate access to daylight and limiting noise pollution. However, since these simulations are usually resource-intensive, timecon

Nya byggnormer – smartare tunnlar? Cut-and-Cover-tunnlar är vanliga vid grund anläggningsnivå i svensk infrastruktur. Dessa betongkonstruktioner utsätts för konstant vattentryck, vilket ställer krav på sprickkontroll. Sprickor uppstår ofta på grund av tvångslaster, exempelvis från temperaturvariationer och krympning, när dessa deformationer hindras av omgivningen. För att begränsa sprickbildning dTunnel structures play an important role in Sweden’s infrastructure. At shallow depths, a common construction method is the so-called “Cut-and-Cover” tunnel, where the tunnel placement is excavated, cast in concrete on-site, and then backfilled. Such tunnels are typically subjected to constant water pressure, which yields high demands on crack control. Cracking in elongated concrete structures oft

När orden mörk materia nämns förs tankarna hos många till sci-fi böcker eller serietidningar. Kanske föreställer man sig en främmande substans i en provrör, eller ett destruktivt svart hål. Sanningen är att mörk materia är mycket mindre dramatiskt än så. Ett definierande drag hos mörk materia är att det interagerar ytterst svagt med vanlig materia. Troligen passerar mörk materiepartiklar rakt igenThe Light Dark Matter Experiment (LDMX) is a fixed-target missing-momentum experiment which hopes to detect dark matter in the MeV-GeV mass range. This is done by firing an 8 GeV electron beam at a thin tungsten target, where the electrons produce dark matter through a process called dark bremsstrahlung. Electrons which have gone through dark matter production can then be found by looking for miss
