Populärvetenskaplig sammanfattning: Under året 2001 kom forskare i hela världen överens om att globala klimatförändringar existerar och att människliga aktiviteter har påverkat dem, framförallt genom utsläpp av koldioxid (CO2). Kyoto Protokollet är en global överenskommelse som kräver en minskning av CO2 utsläpp (med 1990 som basår) och fem andra växthusgaser med 5% fram till 2012. Ett sätt som näIn 2001, the Intergovernmental Panel on Climate Change approved human impact (mainly through the emission of carbon dioxide (CO2)) on global warming. The Kyoto Protocol is a global contract that proposes the reduction of CO2 and five other greenhouse gases by 2012 to at least 5% below the level of 1990. One reduction strategy included in the Protocol is the Clean Development Mechanism (CDM). It su

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the s

Ammonia is considered a promising carbon-free fuel for marine engines, yet challenges persist in utilizing ammonia as a carbon-free marine fuel due to its inherently low reactivity and significant emissions of NOx and N2O. To address these issues, advanced combustion strategies, such as ammonia/diesel dual-fuel Reactivity-Controlled Compression Ignition (RCCI), have been proposed. This thesis pres

Apple is one of the most important pollinator-dependent fruit crops worldwide. To secure high-quality yields, it is crucial to know which, and to what extent, pollinating insects contribute to its pollination success as measured by fruit set, fruit weight and seed set. We perform a meta-analysis of field studies conducted across multiple orchards on insect-mediated pollination in apple cultivation

In older adults, age-related degenerative processes and disorders often degrade some sensory systems more than others, which can make postural control disproportionally dependent on one kind of sensory information. The study aims were to investigate 1) the postural stability when healthy older adults were repeatedly exposed to a video in an immersive virtual reality (VR) environment, and 2) the re

The role of natural marine aerosols in the global climate system remains understudied and uncertain. This is true for the emissions of natural volatile compounds over the ocean, the oxidation of said compounds and their impact on particle formation and particle growth. In this thesis, the emission, chemistry and aerosol particle processes relating to these compounds were studied using different pr

BACKGROUND: Blood-based biomarkers have the potential to reflect cerebrovascular signaling after microvascular injury; yet, the detection of cell-specific signaling has proven challenging. Microvesicles retain parental cell surface antigens allowing detection of cell-specific signaling encoded in their cargo. In ischemic stroke, the progression of pathology involves changes in microvascular signal

Anaerobic fermentation, compared to aerobic processes, remains the most scalable method for bioproduction of compounds. This is due to that aerobic microbial processes require large amounts of energy and are unable to satisfy the oxygen demand of a high-density microbial biomass. Thus, anaerobic microbes are readily scalable to large volumes. It was found that most anaerobic microbes have evolved

Purpose: Reablement is a multidisciplinary intervention aimed at promoting function and independence for people with functional decline. Detailed descriptions of various professions’ actions are needed for organization and evaluation of reablement services. This study describes physiotherapy practice in a reablement context in Swedish municipalities, focusing on the content and magnitude of interv

Functional disruption of the medial temporal lobe-dependent networks is thought to underlie episodic memory deficits in aging and Alzheimer's disease. Previous studies revealed that the anterior medial temporal lobe is more vulnerable to pathological and neurodegenerative processes in Alzheimer's disease. In contrast, cognitive and structural imaging literature indicates posterior, as opposed to a

The existence of workable competition in the marketplace is a fundamental part of a free market economy. Competition is believed to bring many posi­tive effects to both society and the marketplace by ensuring that products and services held in demand are placed on the market at a price that con­sumers are willing to pay. Furthermore, competition results in product effi­ciency. Competing companies

Created in the aftermath of the Second World War the United Nations and its bodies do not represent the world that we live in today. The effectiveness and the usefulness of the organisation have been questioned and the need for a reformation has increased. The distinction between power and authority and the different organs of the UN is difficult to draw. The Security Council has the main responsi

Biopiracy is defined as the commercial development of naturally occurring biological materials, such as plant substances or genetic cell lines, by a technologically advanced country or organisation without fair compensation to the peoples or nations in whose territory the materials were originally discovered. The problem is growing but as of today, there is no common view on how this problem shoul

Climate change is considered to be among the most serious threats to the sustainability of the world's environment, the health and well being of its people and the global economy. The rising levels of greenhouse gases in the global atmosphere are expected to cause a rise in global temperatures. In Kyoto, December 1997, the Kyoto Protocol was written under which industrialised countries have ad

Colorectal cancer (CRC) is one of the most common forms of cancer. The cause of CRC is multifactorial, and lifestyle factors are thought to be a major contributor to the development of CRC. It can be hypothesised that the association between food intake and the risk of developing CRC depends not only on the food consumed, but what it is consumed in combination with. The associations between food a

The measurement of potential enzymatic activities has been proposed as an efficient method to infer nutrient limitations for microorganisms in environmental samples. To validate this use, confirmation with direct methods of microbial growth responses to resource additions are required. We experimentally manipulated nutrient-poor soils from the afromontane subtropics with relatively low (grassland

Power-to-X (PtX) is an emerging approach in decarbonizing industries hard to electrify, and is in many cases requiring stable hydrogen supply to maximize production. Hydrogen is produced via electrolysis and requires large amounts of electricity, which can be expensive, especially when considering highly fluctuating electricity prices. One solution in reducing electricity related costs is to integ

I juli 2024 överlämnade regeringen betänkandet Ett ändamålsenligt samhällsskydd – Vissa reformer av straff- och straffverkställighetslagstiftningen (SOU 2024:48). Syftet med utredningen var att stärka skyddet för samhället, öka tryggheten för brottsoffer samt skärpa konsekvenserna vid återfall eller misskötsamhet. En del av uppdraget var att överväga införandet av en ny tids-obestämd frihetsberövaIn July 2024, the Swedish government submitted the report ”An Appropriate Protection of Society – Some Reforms to Criminal Law and Penal Enforcement Legislation" (Ett ändamålsenligt samhällsskydd – Vissa reformer av straff- och straffverkställighetslagstiftningen, SOU 2024:48). The aim of the government inquiry was to strengthen public safety, increase protection for the victim of crime, and

Beskattning är en central fråga för många företag. För att uppnå en jämnare företagsbeskattning över tid finns det möjligheter för företag att spara under-skott och genomföra underskottsavdrag vid ett senare tillfälle. Det saknas tidsbegränsningar för hur länge ett underskott kan vara ackumulerat vid oför-ändrad ägarstruktur. Om det däremot sker en ägarförändring kan den så kal-lade beloppsspärrenTaxation is a central issue for many businesses. To even out corporate tax payments, it is possible for companies to carry forward losses and make loss deductions in later financial periods. There is no time constraint on how long such a deficit can accumulate if the ownership structure remains unchanged. However, if there is a change in the ownership structure a threshold may be activated and, if

Världshälsoorganisationen har, med hänsyn till den världsomfattande urbaniseringen och åldrandet, föreslagit att tillgängliga grönområden i städers utomhusmiljöer är en viktig aspekt för det hälsofrämjande åldrande. Med anledning av att det främst är den äldre andelen av äldre som ökar globalt, fokuserar denna studie på att undersöka tillgängligheten av grönområden för de äldre som bor i boenden sThe World Health Organization, have due to the current worldwide urbanisation and ageing trends, proposed that having available Urban Green Spaces (UGS) is an important factor for ensuring healthy ageing in urban areas. Since it is particularly the oldest proportion of the older adults that are increasing in global population statistics, this study focused exclusively on available UGS based on old
