Climate change is one of the greatest environmental challenges at the present time and is currently an issue affecting the entire global population. Alternative renewable energy sources are vital to be able to deal with this challenge. Solar energy is one of the most promising renewable energy sources and is therefore also one of the fastest growing industries in this field. However, solar energy
Kerguelenöarna är en vulkanisk ögrupp belägen i det södra Indiska oceanen. Öarna ligger på polarfronten samt inom den cirkumpolära Antarktiska strömmen och södra halvklotets västvindsbälte. Detta gör Kerguelenöarna till en intressant plats för klimatstudier. Av denna anledning erhölls en tre meter lång sekvens av sediment från en sjö på ögruppen 2013. Kol-14 datering av sjösedimenten gav ett gåtfuThe Kerguelen archipelago is a volcanic island group in the southern Indian Ocean. It is located on the polar front as well as within the Circumpolar Antarctic Current and the Southern Hemisphere Westerly Wind Belt. This makes it an interesting location for paleoclimate studies. For this reason, a three meter long sediment sequence from a lake on the archipelago was retrieved in 2013. Radiocarbon
Under certain conditions, the crystal phases in III-V semiconductor nanowires can be controlled, opening up the possibility to create polytype heterostructures with atomically sharp interfaces. The focus of this thesis lies on GaAs nanowires exhibiting the wurtzite (wz) and zinc-blende (zb) crystal structure. Since controlled growth of the wz phase of GaAs has only been achieved recently, knowledg
Möjligheten att korrigera den juridiska könstillhörigheten är en process som realiserades under 1970-talet i Sverige genom en specifik könstillhörighetslag. Lagen innebar en viss frigörelse för människor att själva bestämma vilken könsidentitet de identifierade sig med och skulle stå registrerade under i folkbokföringen. Som motprestation ställdes dock ett antal krav på de personer som ville korriThe ability to change the official gender identification was introduced in Sweden, by a particular law regulation, in the beginning of 1970s century. The law meant a certain liberation for people to, independently decide their one gender identity, and which official gender identification they required to get registered into. At the same time, the law also demanded a several conditions in return of
Strategic alignment has been a top concern for executives for the past two decades. The study aims to investigate how the social dimension of strategic alignment is perceived between an IT department and business department. The study consist of three phases, where the first phase includes two semi-structured interviews to define the problem area at the company in focus. By linking the answers giv
Fjärrvärmeledningar vid två lokaler i Ängelholm har undersökts med två geofysiska metoder, markradar och resistivitetsundersökningar. Fjärrvärmeledningar är ständigt utsatta för påverkan av yttre faktor som t.ex. skjuvspänningar, och inre faktorer t.ex. termal expansion. Som följd av dessa faktorer förslits ledningar i varierad takt och läckage kan slutligen uppstå. Ledningsägare önskar att teknikDistrict heating pipes at two localities in Ängelholm have been investigated with two geophysical methods; ground penetrating radar (GPR) and resistivity measurements (ERT, Electrical Resistivity Tomography). District heating pipes are constantly exposed to the influence of external- and internal forces. As a result the pipes degrade over time, and leakage can eventually occur. Management owners h
A new era of precise time measurement came with the atomic clock. The technology is vital to navigations systems like GPS and to accurate physical measurements. Improvements in laser cooling and the development of frequency combs have combined to enable the construction of clocks using optical reference transitions, which are more stable than the Cesium standard with references in the microwave re
Antalet barn som flyr till Sverige har under de senaste åren ökat. Dessa barn har rätt till en välfungerande skolgång, men kan stå inför vissa utmaningar. Det här arbetets syfte var att undersöka vilka roller som aktualiseras hos skolpsykologer i arbetet med flyktingbarn, vad dessa roller hade för innehåll och vilka utmaningar som kan uppstå. Studiens resultat baserades på intervjuer med fyra skol
Background:The research of social science tends in many cases lean towards an approach that focus on negatively influencing factors, rather than health promoting factors from a salutogenic perspective. In the field of criminology, this approach commonly investigates reasons behind criminal behavior instead of studying the salutogenic factors, i.e. reasons why people do not engage in a criminal lif
This thesis explores seven women’s resistance towards refugee hostile agendas in a Swedish municipality, Sjöbo, renowned for its anti-refugee sympathies. Departing from feminist sociology the thesis places emphasis on the interplay between gender and the field of the political by exploring how specific forms of privileged (white) femininity condition, regulate and shape women’s strategies towards
The current study examined factors that contribute to negative intergroup interactions. More specifically, the present study examines whether ethno-cultural empathy affects people’s beliefs and motivations regarding interactions with refugees/asylum seekers, hypothesizing that (1) internal motivation to respond without prejudice, rather than external motivation is a better ethno-cultural empathy p
En effektiv mjukvarulivscykel och korta iterationer är idag förutsättningar för mjukvaruutvecklande organisationer. DevOps är en uppsättning koncept som ämnar optimera mjukvarulivscykeln genom att strömlinjeforma både utvecklings- och leveransprocessen och således korta ner tiden till marknaden för mjukvaruförbättringar. I ett sådant klimat, där snabba och frekventa releaser prioriteras högt, kan

Methodology: This thesis is based on an ethnographic-inspired methodology to fulfill its aim. Based on a purposive sample 15 semi-structured interviews and 7
The Swedish Water Authorities have proposed a measure to reduce phosphorus losses by restricting manure application on soils with high levels of plant available phosphorus. The aim of this thesis was to investigate if leaching of phosphorus will decrease if the measure is implemented, if the effect is restricted to soils with high phosphorus content and if other European countries have implemented
In Sweden, the number of private extracts from the criminal records registry has increased more than five times since 2003. This is largely due to employers’ request for applicants to submit their criminal record if they want to be considered for a job. This is a phenomenon that is intrusive in the applicants’ integrity and it has become a society level problem. The aim of this paper is to describ
Haloacid dehalogenase (HAD)-like hydrolases represent a vast superfamily characterised by their ability to form covalent enzyme-substrate intermediates facilitating the cleavage of C-Cl, C-P, or CO-P bonds. Within this work one member of this superfamily, HAD from Thermotoga neopolitana (HADTn) exhibiting a phosphatase (P-O bond cleavage) like activity was investigated in the context of altering t
Den informationsteknologiska utvecklingen är något utav både en frälsning och en förbannelse. Å ena sidan ser vi ett stort antal människor för vilka denna utveckling i många avseenden har underlättat deras vardag, å andra sidan ser vi hur upphovsmän och rättighetsinnehavare desperat söker att se efter sina skyddade verk och komma åt intrångsgörare. Genom informationsteknologins näst intill obegränThe development of information technology has had a two-fold effect and therefore it may be considered both a blessing and a curse. On the one hand, we see a large number of people for whom this development has facilitated them to do more in terms of their everyday life, on the other, we see authors and rightholders desperately seeking to look after their protected works and target infringers. The
