The many-body problem in quantum mechanics always presents new challenges and ways to discover new properties of existing materials. The difficulty (if not the impossibility) to solve the many-body problem analytically makes the numerical methods an appealing approach. Here we consider a Python code, which is under development to become an open-source tool to perform studies of finite lattice syst

Syftet med denna studie är att bidra till en ökad förståelse för individens säkerhet, men även att diskutera om utredarna i den svenska utredningen Ordningsvakter och Väktare (Ds 2003:50) tar tillräckligt mycket hänsyn till perspektivet av individens säkerhet och den påverkan som utredningen kan ha på denna. Detta är ett lämpligt perspektiv då det fokuserar på vardagssäkerhet och sätter individersThe title of this study is “The importance of the private security companies for human security – a content analysis of state investigation Ds 2003:50”. The aim of this thesis is to investigate and discuss whether the investigators of the Swedish policy document, Watchmen and Security Guards (Sw. Ordningsvakter och väktare, Ds 2003: 50, have taken sufficient consideration of human security and the

This paper studies the effects of inflation targeting on inflation, inflation expectations, and GDP growth in developed countries, where such a regime has been implemented. The results are compared to those of the control group of developed countries, that have not introduced an inflation-targeting regime. The data is from the period 1980-2017 and is sourced from the International Monetary Fund an

Many companies have traditionally focused on linear product development processes centred on analysis e.g. waterfall or stage-gate processes. Some companies have begun to complement these with iterative product development processes centred on experimentation such as the Lean Start-up Methodology. The knowledge and theory on how iterative processes of product development are best managed is limite

In this paper, I seek to investigate the effect of economic conditions on mental ill health and substance abuse among young adults in Sweden. I investigate whether this effect differs across population subgroups, defined by age, sex, foreign background and educational attainment. In robustness analyses, I also investigate asymmetry in the effect of macroeconomic conditions on mental health and sub

Green bonds are facing prosperity in international and China’s bond market, and becoming increasingly important in the overarching aim of financing green projects to reduce environmental impacts. Therefore, the green degree is an important topic. Based on literature review and interviews, this study defined five key stakeholders in green bond market in China. The regulators are the primary drivin

This thesis examines in which ways the effects of climate change are excluding small-scale farmers from land and capital in in the Vietnamese Mekong Delta. More specifically, it explores the relationship between powers of exclusion and the class differentiation between small-scale farmers in Ba Tri district. Through fieldwork interviews with farmers in Ba Tri district, the findings show that the e

Rhizosphere priming effect (RPE) is a vital progress to regulate soil organic matter decomposition which would influence the carbon cycle in the environment. In my study, Norway spruce and Scots pine were considered to have different RPE because their photosynthetic intensity are different. Spruce had better adaptability of light intensity that it has lower light saturation point (LSP) and lower l

Using Drosophila melanogaster as a study organism, we tried to find differences in male and female attractiveness due to female-limited X-chromosome evolution (FLX). In the first part of the experiment, we tested the male attractiveness (measured as female preference) of the FLX-populations and as a control group we used the LHm-population. (LHm comes from a large laboratory-adapted population co

Riskfaktorer för Parkinsons sjukdom Parkinsons sjukdom är en kronisk, progressiv neurologisk sjukdom som drabbar över 1 % av personer över 65 år. Vid sjukdomen dör nervceller i hjärnan som producerar signalsubstansen dopamin. Dopamin behövs för att skicka signaler mellan hjärncellerna. På grund av bristen på dopamin får hjärnan svårare att kontrollera och styra nervsignaler som bland annat styr kBackground: Parkinson’s disease (PD) is a progressive neurodegenerative disease, affecting over 1% of individuals over the age of 60 years. Approximately 90% of the PD cases are idiopathic, where the etiology is multifactorial and caused by gene-environment interactions. Exposure to various environmental factors have seen to be strongly associated with an increased or decreased PD risk. We aimed t

Climate change and the Little Bustard: Breeding time is of the essence There is a lot of uncertainty concerning how climate change will affect species around the World. We are already observing some ecological changes, such as European butterflies moving their range northwards. However, to predict how species will be affected by climate change is “rocket science”. This study uses GPS coordinate

Can co-chaperone proteins help against Parkinson’s Disease ? Our cells have assigned proteins called ‘chaperone’ and their helper ‘co-chaperone proteins that work extensively to regulate and maintain the protein structure in our cells. However, proteins like α-synuclein manage to clump together in nerve cells and are believed to acquire toxic characteristics that contribute to the death and damag

This thesis aim to visualize and explore the methodological approach to finding the spatial patterning of crime through a geographical information system as a means for future guidance within spatial crime analysis. The analysis was applied to outdoor crimes for the city of Malmö in the year 2007. As a means for conducting this analysis a casestudy is performed. Both as a review of current police-

G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i

I studien används olika metoder, fjärranalys och statistisk analys av satellitdata, samt intervjuer med personer som har god lokalkännedom. Genom att kombinera kvantitativ- och kvalitativmetod har dataanalysens slutsatser kunnat bekräftas. Det aktuella studieområdet liggeSince the mid-1950s, studies have frequently been conducted on couplings between geometrid moth outbreaks and mountain birch, though not nearly as much focus has been on connections between geometrid moth outbreaks and ground cover. Previous studies have shown that major outbreaks of Epirrita autumnata occur in 9 – 10-year cycles (Karlsson et al., 2004). Sometimes also the Operophtera brumata are

During the second half of August and the first part of September 2017, I radiotracked several European nightjars (Caprimulgus europaeus) around the Stensoffa area in Southern Sweden. Several locations were taken for each bird each night, including diurnal roost and nocturnal points composed by flying and resting behaviours. Being a long-distance migrator already on the way south during autumn migr

Optogenetics is unfolding new ways for us to study the nervous system and could one day be a standard approach to treat neurological diseases like epilepsy. To selectively study the effects on a subcellular level, microscopic light sources are needed. Nanostructure, light-emitting diodes (LEDs) can realize this criteria but processing to connect and protect them is necessary before any fruitful op

Fungi belonging to the genus Trichoderma are filamentous and soilborne, and are usually known for their plant growth-stimulating effects. Trichoderma viride is one of the species belonging to the genus, and is recognized as a plant symbiont known to improve plant growth and pathogen protection. Trichoderma species produce certain antifungal and antibiotic agents called peptaibols, as secondary met

The amazing Thermophile Rhodothermus marinus Thermophiles are microorganisms i.e. bacteria and archea that thrive between the temperature 41ºC to 122ºC. As they can grow at extremely high temperatures, they are also known as extremophiles. Mostly, they are found on geothermally heated places like hot springs or deep sea hydrothermal vents. Rhodothermus marinus is a thermophilic bacterium, inte

With protectionism on a global rise, non-tariff measures have been an object for public debates and research, as the work of WTO has reduced the possibilities of raising traditional trade restrictions as customs tariffs. Hence governments have turned to non-tariff measures and regulatory standards to fulfill their agendas. This study aims at shedding light on the question of whether non-tariff mea
