Grundämnena, som bygger upp komplexa molekyler som vårt DNA, är samma material som stjärnor består av. Faktum är att vi människor består till 93 % av så kallat sjärnstoft, eller sjärndamm. De simplaste ämnena, väte och helium, skapades i Big Bang, för ungefär 13,7 miljarder år sedan. De resterande 90 ämnena i periodiska systemet bildas i olika typer av stjärnor och i detta arbete har jag tagit fraPurpose: The purpose of this work is to determine the abundances of neutron-capture elements in solar neighborhood giant stars. This enables constraints to be put on the the cosmic origin of these elements. I have determined abundances of elements produced in both the weak s-process (Cu), the first and second s-process peaks (Y, Zr and La, Ce, Pr, Nd, respectively) and the r-process (Eu, Gd). The

The Light Dark Matter Experiment (LDMX) is a fixed target experiment that will search for dark matter, but is still in the development phase. An important aspect for the experiment is the discrimination of signal and background events. Here this signal and background discrimination is inspected using a machine learning technique called a Boosted Decision Tree (BDT). This is done using Monte Carlo

This paper examines the effect of homework on student achievement using data from 57 countries that participated in PISA 2006. For that, we use a within-student identification strategy that allows us to account for most confounding influences at the country, school and student level. We find that homework has a positive and highly statistically significant effect on student test scores. The hetero

The purpose of this paper is to examine if foreign aid leads to a higher level of development when it is given to countries with higher levels of gender equality. The study examines the effects that foreign aid and gender equality have on development by assessing both their separate and interactive effects. I have used three different models, using two definitions of development and gender equalit

The European Union’s (EU) ‘market-oriented’ approach to renewable energy development risks undermining the ability of individual citizens to meaningfully contribute to, and benefit from, a decentralised, localised, and decarbonised energy system. In spite of the EU’s ambition to involve local communities for co-driving a low-carbon energy transition, there is no comprehensive analysis uncovering t

I Sverige drabbas ca 100 000 patienter av vårdskador varje år. Postoperativ sårinfektion är en vårdskada som medför lidande och omfattande kostnader för hälso- och sjukvården. Samtidigt råder det stor personal- och tidsbrist inom operationssjukvården. Syfte: Undersöka förekomst av bakterietillväxt på uppdukningsbord över totalt 12 timmar. Metod: En jämförande observationsstudie med kvantitativ an

In Germany, country of diesel bans and postponed climate goals, the region of Baden-Württemberg, as the heart of the country’s car industry, faces especial challenges. Due to its highly car-oriented transport system and topographical structure, the region is notorious for some of the country’s worst air quality levels. In response to these issues, the regional government formulated a cycling strat

By 2050, sixty percent of human population worldwide is going to live in cities. This will increase natural resource consumption to provide products and services in cities. Additionally, current policy making is done through a silo thinking mindset where unintended consequences can undermine natural resources availability. To overcome this problem, I propose to use the urban nexus approach as a st

Syftet med studien var att undersöka upplevelser av babyrytmik och vad som kan uppnås genom babyrytmik i en verksamhet tillhörande Svenska Kyrkan i Malmö. Litteraturkapitlet beskriver begreppet rytmik och dess bakgrund, babyrytmik, barns upplevelse av musik och rytmik, samt barns utveckling kopplad till musik och rytmik. Studien innehåller också en intervju med kyrkans rytmikpedagog samt en fokusgThe purpose of the study was to examine experiences of Eurhythmics for Infants and what can be achieved through Eurhythmics for Infants in classes associated with the Church of Sweden in Malmö. The literature review describes the concept of eurhythmics and its background, Eurhythmics for Infants, children's experience of music and eurhythmics, and children's development linked to music and

Generellt sett gäller tvister vad som har inträffat i verkligheten och parternas faktaberättelser består av faktiska omständigheter. Vilken betydelse som en omständighet får för utgången av en tvist avgörs av vilken processrättslig kategori som omständigheten hänförs till. Vilka omständigheter som parterna måste åberopa för att domstolen ska få beakta dem avgörs av reglerna om åberopsbörda. När paDisputes generally revolve around what, in reality, has occurred and the parties, therefore, tend to focus on presenting different stories as to how the dispute arose in the first instance. In deciding which series of events should form the basis for the application of the law in question, the court seeks guidance from a plethora of procedural rules. These rules state (i) which party must provide

Syftet med denna studie var att beskriva och analysera hur arbetet med ensamkommande barn bedrivs. Forskningsfrågorna fokuserade på hur integrationshandledare arbetar för att tillgodose barnens behov, hur de arbetar med integrationsprocessen och slutligen vilka utmaningar de möter i arbetet. En kvalitativ ansats valdes med semi-strukturerade intervjuer med fem integrationshandledare som primärdatThe purpose of this study was to describe and analyse how the work with asylum-seeking children without parents or guardians is conducted. The underlying questions focused on how the integrations handlers work to fulfil the needs of the children, how they work regarding the children’s integration processes, and finally what challenges they encounter in their work. A qualitative approach was chose

A case-study was conducted in the village of Drawuvalu. Data was gathered through semi-structured interviews and observations. The composition of livelihoods at the t

This is a project in product development made for ASSA ABLOY Entrance Systems which is a manufacturer of sliding doors among other products. The objective of this project is to come up with a solution which offers an improved air sealing capability for a set of sliding doors all while the friction remains either the same or lower compared to before.

Det juridiska ramverket för arbetskraftsinvandring reformerades under 2008 för att möta det ökade behovet av arbetskraft från tredje land. Genom reformen förenklades processen för arbetsgivare att anställa utländsk arbetskraft utifrån den enskilde arbetsgivarens behov. Vid införandet av det nya regelverket avskaffades den tidigare arbetsmarknadsprövningen och det infördes krav på att de löne-och aIn 2008 the legal framework for labour immigration was reformed to meet the increased demand of third country workers, due to a labour shortage in Sweden. The reform simplified the recruitment of third country workers by allowing employers to conduct an assessment of their need for these workers. The introduction of the new framework included the abolishment of the former labour market examination

The Iron Closet has always been deep, and although never leading to Narnia it has on occasions had the potential to be a one-way ticket to a forced labour camp. After the decline of the Soviet Union, however, the Western world rejoiced; the second parenthesis had been set out and we now lived in the main narrative again where everything ought to make sense. Countries in the post-Soviet space would

The purpose of this study was to investigate social workers’ experience of communicating with children using an interpreter and analysing the challenges. We conducted qualitative interviews with the focus groups of social workers in a city in the southern part of Sweden. They all served at the social services in the municipality. Totally, four focus group interviews were conducted with four partic

Ett barn med funktionsnedsättning kan ansöka om bistånd för att avlasta föräldrarna i vårdnadsansvaret. Vid bedömning om bistånd ska beviljas eller inte, ska beslutsfattaren bedöma föräldraansvarets omfattning. Föräldraansvaret är ett begrepp som syftar till att jämföra det ansvar en förälder till ett barn med funktionsnedsättning har och det ansvar en förälder till ett barn utan funktionsnedsättnA child with functional impairment can apply for social assistance in order to relieve their parents from the responsibility of care to either Social Services Act (2011:453) (SoL) or Support and Service for Person with Certain Functional Impairments act (1993:387) (LSS). During the assessment of whether the social assistance shall be granted or not, the decision-making officer must assess the scop
