The study conducts a life cycle assessment of both the trucks, focusing on CO2 emissions during production and use phases, and evaluates the total cost of ownership, considering vehicle cost, fuel, maintenance, and resale value. The data inputs ar
”’Till livet!’: Fallet, identitetstematik och den Andre i tre pjäser av August Strindberg” undersöker fallmotivet som spatial händelse samt dess konsekvenser i tre pjäser av August Strindberg: Lycko-Pers resa (1882), Fröken Julie (1888) och Ett drömspel (1902). Ämnesvalet grundar sig i iakttagelsen att Strindberg återkommande använder rumsligt vertikala uttryck – något som tidigare inte har ägnats
Efter att Mahmoud Ahmadinejad kom till makten i Iran 2005 började han direkt förbereda för den mytiska Mahdins återkomst. Ahmadinejad har en bakgrund i den terrorstämplade organisationen Islamiska revolutionsgardet IRGC. I västvärlden har han gjort sig känd genom sina antiisraeliska uttalanden och kritik mot västvärlden. Men även genom rapporter om korruption och valfusk. Uppsatsen undersöker om o
Flyxensjön, som utgör källan till avrinningsområdet, har god vattenkvalitet. Men när floden rinner vidare och korsar flera torvmarker försämras vattenkvaliteten avsevärt, vilket understryker det akuta behovet av att undersöka påverkansfaktorerna i detta avrinningsområde. Denna studie undersöker de rumsliga och tidsmässiga variationerna i vattenkvaliteten längs Kåtån, från Flyxensjön till sjön KöseThe Lake Flyxen, as the headwater of the watershed, maintains good water quality. However, as the river flows downstream and intersects several peatlands, the water quality deteriorates significantly, highlighting the urgent need to investigate the influencing factors in this watershed. This study examines the spatial and temporal variations in water quality along the Kåtån River from Flyxen Lake
Open-source microscopes like the PlanktoScope have recently gained attention as affordable tools for studying plankton diversity. Compared to commercial systems, they are low-cost, modular, and suitable for both scientific research and citizen science projects. In this study, we assembled and tested the PlanktoScope v.2 system to evaluate its performance in identifying and quantifying freshwater a
High-order harmonic generation (HHG) is a highly nonlinear optical process in which extreme ultraviolet (XUV) radiation is generated due to the interaction of an intense laser field with atoms. This process enables the production of high harmonics, which would not be achieved with standard nonlinear media. The utilization of two-color laser fields (formed by combining a fundamental field with one
In the background of intensifying global climate change and rapid urbanisation, the frequent occurrence of extreme hydrological events and the increase in surface pollution pose serious challenges to the environmental quality of water bodies. Moreover, with the significant increase in public awareness of environmental protection, higher demands have been placed on water quality monitoring techniqu
Klimatförändringen är en realitet som våra kritiska infrastrukturer måste anpassa sig till för att stå emot framtida hot. En analys av fem infrastrukturer – elnät, ICT, järnväg, fjärrvärme samt vatten och avlopp – visar stora skillnader i klimatanpassningsarbetet. Järnvägen har kommit längst, medan fjärrvärmen har störst behov av utveckling. Det övergripande största problemet är bristande samarbetClimate change is a reality, with no indication of slowing down or reversing. Climate change causes extreme weather to occur more intensely and frequently. This poses a significant threat to critical infrastructures, which must adapt to withstand the new conditions they are increasingly exposed to. Climate change adaptation are measures which have the purpose to lessen the negative effects of clim
Industrial meat production causes immense suffering but continues on a massive scale. This study explores how the concepts of carnism by Melanie Joy and commodity fetishism (CF) by Karl Marx inter¬sect to enable the societal dissociation from the abusive interspecies relations behind industrial meat production. Moreover, the study develops a new concept called meat fetishism (MF) which highlights
The rapid advancement of computer vision, powered by large-scale visual datasets and deep learning, has raised pressing concerns about privacy, particularly when human faces are involved. This work explores how facial anonymization affects the performance of human detection models, aiming to balance identity protection with model utility. A range of anonymization techniques are applied, including
Frånvaron av ett omedelbart kostnadsansvar i förvaltningsprocessen innebär att enskilda i dagsläget är hänvisade till ett separat skadeståndsförfarande för att få sina rättegångskostnader i förvaltningsmål ersatta. Förvaltningsprocess-lagens [1971:291] (FPL) avsaknad av direkta ersättningsbestämmelser likt de som gäller i civila tvistemål har en rad förklaringar till sig. Förstone handlar det om hThe absence of an immediate cost liability in administrative proceedings means that individuals are currently referred to a separate tort proceeding to be compensated for their litigation costs in administrative cases. The lack of direct compensation provisions in the Administrative Court Procedure Act [1971:291] (FPL) has several explanations. Firstly, it concerns how the com-mon foundations of t
Materien som vi består av och kommer i kontakt med är uppbyggd av atomer med kärnor bestående av protoner och neutroner. De är exempel på hadroner, partiklar sammansatta av de fundamentala partiklarna kvarkar och gluoner. Dessa interagerar via den starka kraften, vilken likt gravitationen, elektromagnetismen och den svaga kraften är en fundamental kraft som styr utformningen av vårt universum. UndStrong force dynamics in the non-perturbative regime remains a poorly understood aspect of quantum chromodynamics. In collisions of heavy ions, the near-side ridge and enhanced elliptic flow are widely regarded as signatures of the collective motion of deconfined partons in a thermalized medium. On the other hand, no corresponding explanation has been found for the appearance of these signatures i
Denna avhandling föreställer sig en ny typ av typologi i staden, en som är sådd och odlad av och för de äldre och de unga. Ett mötesrum som främjar generationsöverskridande relationer och samarbete, samtidigt som det minskar ensamhet och främjar stimulerande miljöer för social utveckling. Genom att omvandla en oanvänd parkering i centrala Stockholm till ett gemensamt utrymme som är delvis trädgårdThis thesis imagines a new type of typology in the city, one that is seeded and cultivated by and for the elderly and the young. A meeting space that fosters intergenerational connections and collaboration while reducing loneliness and promoting stimulating environments for social development. By transforming an unused parking lot in central Stockholm into a shared space that is part garden, part
The harbour porpoise (Phocoena phocoena) is affected by anthropogenic activities in Swedish waters, and the individuals found in the Öresund belong to the Belt Sea population, which is classified as ´vulnerable´. Boat traffic is known to have a negative impact on porpoises. Behavioural responses to such disturbances are context-dependent, and locally specific knowledge is needed for effective mana
This study aims to increase the understanding of the parents' experiences with children sitting at home. Furthermore, we want to contribute knowledge of how parents experience the relationship with professionals and how they experience the support offered. The research method we used was qualitative, with six semi-structured interviews. We chose parents because their children are of primary sc
This study examined how the number of explanatory variables included in a linear regression model affects model quality. The maximum number of variables was set to 20 and only models describing quantitative data were studied. The effect on model quality was studied through comparisons of models with different numbers of explanatory variables. The models – and the data sets the models were derived
This study aims to explore the complex positions of men as both victims and perpetrators within the context of honor-based violence and oppression. A qualitative method, utilizing self-biographies written by women, examines how the established norm of masculinity in honor culture portrays men as victims and perpetrators. The analysis focuses on two primary themes: “men as victims” and categories s
Gender norms seem to affect social workers' evaluation of children in childcare investigations in Sweden. This essay aimed to determine whether social workers at a Swedish social service center write differently about boys and girls in child care investigation documents based on the children's gender. The sample consisted of nine randomized investigation documents on four boys and five gir
Emotionsreglering (ER) innebär en förmåga att moderera varaktigheten och intensiteten av negativa känslomässiga upplevelser. Den aktuella studien utökar tidigare kunskap om ER i tonåren genom att anta en personcentrerad ansats för att undersöka profiler karaktäriserade av olika användning av följande ER-strategier: ruminering, socialt stöd, positiv omorientering, distraktion, kreativitet och aggreEmotion regulation (ER) refers to the ability to moderate duration and intensity of negative emotional experiences. The current study extends existing knowledge of ER in adolescence by adopting a person-centered approach to examine ER profiles characterized by different uses of the following ER strategies: rumination, social support, positive reorientation, distraction, creativity and aggression,
