I denna uppsats presenterar jag kristallisationsåldrar, petrografi och geokemisk sammansättning för diabasgångar och en lagergång i östra och sydöstra Kaapvaal kratonen, Sydafrika. Dessa nya resultat ger mer exakta och pålitliga resultat än tidigare dateringar för diabaser tillhörande den s.k. Mashining gångsvärmen, vilka daterats till 2253 ± 45 and 2202 ± 74 Ma (Ma = miljoner år). De nya resultatIn this study, I present emplacement ages, petrography and the geochemical composition of doleritic dykes and one sill from the eastern and south-eastern area of the Kaapvaal Craton. These results refine the previous 2253 ± 45 and 2202 ± 74 Ma ages of the Mashining event to ca. 2168 Ma, and shows that this swarm is intermixed with the younger 1875-1835 Ma Black Hills dyke swarm. Geochemical data o

In Zambia recent socio-economic changes are placing an undue burden on the elderly. The burden is greatly associated with the HIV and AIDS epidemic, which has led to increased mortality of prime aged adults. As a result of this the elderly are called upon to shoulder the responsibility of the family, as they become the principal caregivers for young children. The traditional family roles are being

Vi rör oss ständigt i offentliga rum som på olika sätt är utformade för att påverka oss. Denna studie undersöker om människors känslor, syn på välbefinnande och syn på meningen med livet påverkas av att befinna sig i olika rum, i detta fall en kyrka (N=51) och ett köpcenter (N=51). Två verktyg, semantiska mått och Positive and Negative Affect Schedule (PANAS) används för att undersöka om det finnsWe are constantly moving between environments that are designed to affect us in one way or another. The purpose of this study is to investigate if the room has an influence on people's feelings, and their views on well-being and meaning of life. In a randomised experiment, the study explores whether there is a measurable difference in the participants’ feelings and thoughts in a church (n=51)

Understanding the patterns of evolutionary sequence divergence is fundamental for comparative analyses like phylogenetics or genomics. The rate at which the different sites of protein sequences evolve is multifactorial and the causes of variation among them are highly convoluted. Inference methods have been developed to estimate site-specific evolution rates from sequence alignments. Moreover, sev

There has been an increase in emergency preparedness measures aimed at individual households in the recent years in Sweden. The reason for this is that the Swedish government have deemed Swedish households' preparedness to be deficient and in need of improvement in order to better meet the risks of the modern society. It has been done through a number preparedness-raising campaigns. Risk commu

Att detaljhandelns förändring påverkar den fysiska butiken är ingen nyhet. Konsumenter rör sig mer och mer mot e-handeln, och det vi tidigare vetat om konsumentens beteende i handeln sätts på prov. Marknadsföringens roll i konsumentens köpprocess har studerats och diskuterats av flertalet forskare, under lång tid. Men hur ser det ut när marknadsföringen, likt detaljhandeln, utvecklas?

This Master’s project presents on the angular dependence of the intensity of the Raman active phonon modes of Black Phosphorus (BP), a layered 2D material with unique and attractive characteristics to the scientific and engineering community. Raman spectroscopy is an indispensable tool in quick and unobtrusive analysis of chemical structures. In this Master project, the structure of BP is analyzed

Denna studie syftar till att undersöka vad en kreativ lärmiljö innebär för elever på det estetiska programmet i musik. Vidare avser studien att ta reda på vilka faktorer som påverkar den kreativa lärmiljön för att förstå hur en sådan miljö kan skapas i skolan. Bakgrunden till studien är författarens eget intresse för hur den fysiska miljön kan uppmuntra eller hämma kreativitet samt en ökad efterfrThis study aims to investigate what a creative learning environment means for music students in upper secondary school. Furthermore, the study aims to find out what factors affect the creative learning environment in order to understand how to design a creative learning environment in music education. The background to the study is the author's own interest in how the physical environment can

År 2011 utbröt den sociala och politiska revolution i Syrien som senare utvecklades till en väpnad konflikt mellan regimen och olika väpnade folkliga grupper. Under perioden mellan 2012 och 2018 eskalerade konflikten och bredde ut sig i stort sett över hela Syrien. Konsekvensen av detta var storskaligt på den humanitära nivå, då hälften av befolkningen tvingades migrera inom eller utom landet och

Risk communication, the flow of information between decision-makers, risk experts and the public, can be a valuable tool in societal resilience building. Risk communication can be used both to inform the resilience planning process as well as to directly build resilience at all societal scales. The city of Belfast is currently developing a resilience strategy that addresses flooding in the city as

This thesis is divided in two with a theoretical research question as well as a practical research question. The theoretical question I sought answered was: Can architects support democracy? The question was sought answered through a literature study from which I concluded that especially two out of the many prerequisites for democracy relates to architectural practice: A need for a sense of “we”

Two deep learning techniques for classification on corrupt data are investigated and compared by performance. A simple imputation before classification is compared to imputation using a Variational Autoencoder (VAE). Both single and multiple imputation using the VAE are considered and compared in classification performance for different types and levels of corruption, and for different sample size

Uppsatsen behandlar det praktiska förnuftets första principer enligt St. Thomas rättsfilosofiska teori. Den tar sin utgångspunkt i två nutida författares tolkningar av denna och jämför dessa bådas tolkningar av St. Thomas originaltexter. De båda författarna är Jean Porter respektive Germain Grisez. Uppsatsen finner att de främst är eniga, men punkter där de tycker olika hittas också. Uppsatsen böThis paper covers the subject of the first principle of practical reason in the legal and moral theory of St. Thomas of Aquinas. It takes its starting point from the two Contemporary authors Jean Porter and Germain Grisez. It compares these two authors view of the operations and function of the practicla reason in the theory of St. Thomas. It focuses on similarities and differencis between the two

Energy use in buildings contributes significantly to the global energy demand and environmental impacts. Among all building services, heating, ventilation, and air conditioning (HVAC) systems consume the most energy. HVAC systems are as well one of the largest consumers of natural resources and materials in the building sector. Studies have shown that the manufacturing and operation of HVAC system

This thesis explores representations of duality across the work of contemporary Native American poets. Through the use of several analytic methods and postcolonial theories, this thesis will analyse representations of language, place, and identity, and argue that they are constructed in the border between Native American and American consciousness. Firstly, Tommy Pico’s Nature Poem will be read a
