The wide variety of physical phenomena, such as motion of objects, reaction among chemical substances, electricity flow in a circuit can be described by equations with quantities that vary along time.The rate at which a quantity is changing with respect to its independent variable (time), is represented by its derivative. Thus, these phenomena are modeled by equations with differential variables Adaptive multistep methods have been widely used to solve initial value problems. These ordinary differential equations (ODEs) may arise from semi-discretization of time-dependent partial differential equations(PDEs) or may combine with some algebraic equations to represent a differential algebraic equations (DAEs).In this thesis we study the initialization of multistep methods and parametrize som

The global food industry is the second main contributor to climate change whilst climate change also poses threats to future food security (Ritchie & Roser, 2020). One of the suggestions to decrease the environmental footprint of consumption and increase the resilience of food systems, is the shift to local production and consumption (Stein & Santini, 2021; Van Gameren et al., 2015). Howev

The Swedish government submitted proposal 2007/08: 95 to the Parliament (Riksdagen) in 2007. The proposal contains the main ideas and pricipals of Sweden's first cohesive discrimination law. The proposal aims to describe how the legislation should act more efficiently and comprehensively, something the older laws could not manage. The aim of this thesis has been to explain the problems associa

beta-Microseminoprotein (MSP) is one of the most abundant proteins in human seminal plasma and is secreted from the prostate gland. Its evolution can be traced from primates down to nonvertebrate species such as amphioxus, despite substantial differences in the primary structure. Most mammals are known to have one single MSP gene, but we have previously shown that the cotton-top tamarin and the co

This paper seeks to examine trends in Chinese household consumption. It is comprised of a two-fold study, which undertakes both an exploratory and an explanatory approach. First, an analysis into the nature of household consumption examines trends in purchasing habits. Specifically, data on the consumption and prevalence of durable household goods and major food commodities is gathered to establis

In this thesis, I explore the labor policy design change in the framework of the EU integration process in Georgia. The thesis aims to understand the incentives for recent changes in the labor policy domain covering the years 2014 and 2024, in particular, whether changes were a product of external incentives stemming from EU integration goals or it was the result of internal political will aiming

The Swedish Stroke Register (Riksstroke) was founded in 1994. Riksstroke includes registration of acute stroke, with a follow up after 3 months and 1 year. The Stroke policy and quality register research group has several ongoing projects based on data from Riksstroke, and in many studies also using data record linkage to other national registers and data bases.

This thesis analyses how the Austrian humanitarian and developmental organisation Hilfswerk International discursively legitimates its involvement in border externalisation and containment practices in Bosnia and Herzegovina and the Western Balkans. Whilst previous scholarship has thematised the confluence of humanitarian principles, borderwork, and “migration management”, insufficient attention h

Popular Abstract in Swedish Städer har kommit att framstå som alltmer drivande i arbetet med att ställa om till ett ekologiskt hållbart samhälle. Utöver att genomföra statliga direktiv eller fokusera på klassiskt kommunala uppgifter som fysisk planering eller renhållning, har kommunala politiker och tjänstemän alltmer kommit att driva en egen miljöpolitik på lokal nivå. Ett exempel är energi- och Local governments are increasingly taking the initiative in environmental governance. But can they make any difference in addressing current environmental challenges, which are becoming more and more global in scope? This PhD thesis explores and analyses the outcomes of proactive initiatives in the field of building energy efficiency, and the governance approaches taken. It addresses outcomes both

Brazil has recently become the fifth largest producer and fourth largest exporter of cotton in the world. This success story is exceptional, as the Brazilian cotton production reached record low levels in the mid-1990s. Since then however, production has more than recovered owing to an impressive growth of 43 % during the last decade, which is high in comparison to the world average of 28 %. The p

Popular Abstract in English Imagine you are sunbathing on a sandy beach, while reading the latest Dan Brown book. Once the book is finished, you look at the waves and notice that in one place, they decelerate and become large. Excited by your reading, you imagine that beneath those larger waves there is a ship containing a treasure in it (most likely sunk by the Illuminati during World War II). BuThis thesis describes how photoemission stimulated by an attosecond pulse train (APT) can be used to extract information on electron correlation in simple quantum systems such as atoms. The emission of the electron by an APT induces a reorganization of the electrons remaining in the ion core. This reorganization causes a change in the trajectory of the emitted electron. An infrared (IR) field is u

This paper investigates if the importance of sunk costs differs between markets with different exchange rate risk. First, it examines the importance of sunk costs on the export participation decision by estimating the effect the previous export status has on the current export decision. Second, it analyses the effects of product-market characteristics on the export participation decision. Third, i

Popular Abstract in English In our current world, the exponential growth in demand for smaller and faster devices leads to the fact that we will eventually face the problem that traditional semiconductor technologies will reach their limitation in terms of size and speed. Humanity's consciousness to tackle the global ecological issues in the next decade, will demand the substitution of all non-reuThe work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. for the development of organic molecule-based dev
