Assessing the Carbon Intensity of Hourly Electricity Mix in Sweden and Identifying Opportunities for Renewable Energy Integration (2018-2022)

The carbon intensity is an important metric that provides a clear measure of the environmental impact associated with the electricity use. Carbon intensity of electricity use is differentiated into CO₂ equivalents per kilowatt-hour, which standardises the measurement by expressing the emissions of various greenhouse gases in terms of the equivalent amount of CO₂ based on their global warming poten

Det skiftande förtroendet: En kvantitativ studie om studenterns mellanmänskliga och politiska förtroende

This paper presents a study about whether university student's political and interpersonal trust is affected by gender and educational field. A primary question was also to study whether there was a difference in students’ trust in how social problems are managed and prevented by Sweden's elected politicians. In this study, the theory about social capital is applied where political trust c

Anstiftan till mord - En uppsats om anstiftarens ansvar vid beställningsmord inom den kriminella miljön, med särskilt fokus på error in persona

Den organiserade brottsligheten står för en betydande andel av beställnings-morden som utförs i samhället. Uppsatsen syftar till att utreda hur den krimi-nella miljöns struktur och hierarki påverkar möjligheten att identifiera och åtala personer för anstiftan till mord. Det finns ingen legaldefinition av begreppet organiserad brottslighet men Brå har tagit fram kännetecken. Organiserad brottsligOrganized crime accounts for a large share of the contract killings committed in the society. The essay aims to investigate how the structure and hierarchy of the criminal environments affects the possibility to identify and prosecute individuals for incitement of murder. There is no legal definition of the concept organized crime, but Brå has devel-oped characteristics. Organized crime concerns

“Kamp och seger på den svenska arbetsmarknaden” - En narrativ analys om de hinder och möjligheter som individer med utländsk bakgrund möter i sin strävan att etablera sig på arbetsmarknaden.

In Sweden, a prevalent topic of discussion revolves around the challenges faced by immigrants when attempting to integrate into the Swedish labor market. The aim of this study was therefore to examine obstacles and opportunities that individuals with a foreign background face and how their actual identity is affected by the establishment and making a career. Employing a qualitative approach with a

Conventional and novel anti-seizure medications reveal a particular role for GABAA in a North Sea progressive myoclonus Epilepsy Drosophila model

Objective: North Sea Progressive Myoclonus Epilepsy (NS-PME) is a rare genetic disorder characterized by ataxia, myoclonus and seizures with a progressive course. Although the cause of NS-PME is known, namely a homozygous mutation in the GOSR2 gene (c.430 G>T; p. Gly144Trp), sufficient treatment is lacking. Despite combinations of on average 3–5 anti-seizure medications (ASMs), debilitating myoclo

Endokrin oftalmopati ur fyra olika perspektiv

Graves' orbitopathy is a common complication of Graves' disease. The mild form dominates, whereas moderate to severe and sight threatening forms are rarer. They require quick, adequate care, involving cooperation between county hospitals and the regional hospital, and adequate diagnostics and choice of treatments of treatments. A new national guideline for hyperthyroidism has been published in Swe

Soil microbial functions are affected by organic matter removal in temperate deciduous forest

A growing demand for renewable carbon (C) has led to intensified forest management resulting in the use of forest residues (e.g. canopy, bark or litter layer) as energy sources with potential modifications of soil properties and tree productivity. Because microbes mediate the recycling of C and nutrients sequestered in organic matter, we investigated the effects of organic matter (OM) removal on s

Stem-inhabiting fungal communities differ between intact and snapped trees after hurricane Maria in a Puerto Rican tropical dry forest

Hurricanes impact forests by damaging trees and altering multiple ecosystem functions. As such, predicting which individuals are likely to be most affected has crucial economic importance as well as conservation value. Tree stem-inhabiting fungal communities, notably rot-causing agents, have been mentioned as a potential factor of tree predisposition to hurricane damage, but this assumption remain

Det svenska offret – En diskursanalys av Sverigedemokraternas användning av begreppet svenskfientlighet och dess högerpopulistiska innebörd

Högerpopulismens framväxt under de senaste decennierna är idag ett faktum. Även i Sverige har denna ideologiska familj nått nya höjder på grund av Sverigedemokraternas historiskt snabba valframgångar och med SDs intåg i riksdagen 2010 introducerades även ett nytt begrepp i den svenska politiken, nämligen svenskfientlighet. Denna uppsats har, genom en kritisk diskursanalys, studerat SDs användning
