Bus transportation is a fundamental part of Sweden’s public transport system. To ensure its competitiveness and attractiveness compared to cars, it is important to continuously improve and maintain the bus service. The study examined how different speed bumps impact bus transportation, focusing on two main factors: travel time and passenger comfort. The study is based on speed and vibration measu
Kalkbildande nannoplankton anses vara de mest produktiva kalkproducerande organismerna på jorden och spelar en avgörande roll i den marina kolcykeln. Dessa organismer uppträdde först i västra Neo-Tetishavet under Karn (första etagen i Yngre trias) och har sedan dess varit viktiga bidragare till ackumuleringen av kalciumkarbonat i marina sediment. Sen rät (sista etagen i Yngre trias) representerar Calcareous nannoplankton are considered the most productive calcifying organisms on Earth and play a critical role in the marine carbon cycle. These organisms first appeared in the Western Neo-Tethys Ocean during the Carnian (early Late Triassic) and have since been key contributors to calcium carbonate accumulation in marine sediments. The Late Rhaetian represents a critical interval for investig
This report is written to support SAAB Kockums AB in their investigations of whether it is necessary to replace their current Novec 1230 fire extinguishing system in electrical cabinets due to environmental restrictions, and what type of agent that would be a suitable replacement. The work focuses on determining consequences of a fire in an electrical cabinet regarding different aspects such as: f
This thesis compares the costs and greenhouse gas emissions of long haul trucks powered by battery electric and fuel cell electric technology in Sweden. 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
Climate 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
Strong 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 trädgård
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
As many arthropods, telecoprid dung beetles are deeply affected by anthropogenic pressures, including the extensive use of pesticides. Ivermectin, the main endectocide employed to treat livestock nowadays, drives population and species loss, and causes locomotion and sensory disorders in dung beetles. Imidacloprid, the major insecticide used to combat crop pests, is highly toxic towards pollinator
Bumblebees are essential pollinators, sustaining ecosystem balance and aiding crop pollination. A comprehensive understanding of their foraging ecology is therefore crucial. We studied the influence of life-history traits of individual Bombus terrestris on wing wear and its foraging patterns. Wing wear is clearly a widespread phenomenon observed in all flying insects. Wing integrity has consequenc
In a world of rapid biodiversity loss, raptors are vulnerable due to their longevity and low reproductive rates. The red kite (Milvus milvus) is one of few migratory raptors breeding exclusively in Europe. It has previously experienced steep population declines caused mainly by persecution but mostly recovered, no longer classified as globally endangered. However, negative population trends persis
