This study presents U-Pb baddeleyite ages for five dolerite dykes and one sill in the Mesoarchean granitic basement of south-easternmost Kaapvaal Craton in northern KwaZulu-Natal, South Africa. The oldest dyke is ENE-trending, and is dated to 2729 ± 5 Ma. One ENE- and two SE-trending dyke are dated to 2580 ± 3 Ma, 2574 ± 5 Ma and ˃2517 ± 5 Ma (minimum age for the latter given by the 207Pb/206Pb da

This master thesis addresses the electrically powered assisted bicycle (EPAC) as a future low-carbon commuting option and its market. The purpose of the report is to evaluate whether the EPAC can be used to improve the climate performance of the transport sector and to assess the outlook for the Swedish EPAC market. The EPAC is compared to the bicycle, car, bus and train and assessed thereafter. T

The aim of this thesis is to examine how Turkey’s “proto-transition” regarding the Kurdish issue is gendered in the light of the narratives of a particular set of victims, the wives of the disappeared. The conflict between the Turkish military and the Kurdistan Workers’ Party (Partiya Karkerên Kurdistan or PKK) has been ongoing for more than three decades. During 1980s and 1990s, enforced disappea

Foraminiferer förekommer i marina sediment i världens hav och utgör en värdefull proxymetod för att rekonstruera vattendjup, strömmar, produktivitet och syrenivån vid djuphavsmassor. Valet av storleksfraktion som används när studier på bentiska djuphavs-foraminiferer utförs har visat sig ha betydelse när ekologisk fauna vid upvällningsregioner studeras. En genomgång av tidigare studier har visat aForaminifera are abundant in the marine sediment in all of the worlds’s oceans and offer a valuable proxy method to reconstruct water depth, circulation, productivity and deep water aeration. The choice of size fraction used when studying benthic foraminifera in upwelling areas are important. A review of 15 earlier studies where benthic foraminifera has been analysed, has shown that there are diff

When the international monetary system was on the gold standard, China was the only country adhered to the silver standard. Silver functioned as currency in China but acted as commodity in international markets. Its price experienced downturn trend from 57 cents per ounce in January 1929 to 23.38 ounces per ounce in January 1933. Then it increased to 75 cents per ounce in May 1935. Dramatic fluctu

Biogas production is a renewable energy technology of great potential. The produced gas can be used for heat production, combined heat and power production, vehicle fuel production or as replacement for natural gas. The technology brings about synergic benefits as it is a means of waste management and since the digested material is a valuable fertiliser.An increased production of biogas is advocat

The telecom and the IT-industry are converging, which creates new possibilities and threats for both existing mobile handset vendors and new entrants originating from the IT-industry. The purpose of this thesis is to explain how IT-players’ entrance in the mobile handset industry affects the industry in regards of key success factors and value chain structure. This study has used dynamic theories

In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. Imaging through scattering media is used in Bio-Medicine when looking through human skin; in characterization of spray systems in Combustion Engineering as well as in other applications where

In 2015, 19.2 million people have been internally displaced globally in the context of disasters (IDMC, 2016). This is more than twice the number of people who have been newly displaced by conflict in the same period (IDMC, 2016). The small island developing states (SIDS) in the Pacific and the Caribbean belong to the most hazard-prone regions of the world. Yet, the dynamics of disaster-induced di

Professional counselors are often seen as responsible for highlighting the need of, and to operate the social work in healthcare. To have that expertise in an otherwise medical context can lead to it being a difficult task. It is also suggested that the social worker’s role and professional identity is vague, which also influences social worker’s jurisdictional work. The aim of this study was to i

This thesis explores the structure and discursive frames in the rhetoric of the online extreme right network in Finland. Departing from the constraints of identity and ideology, the individual nodes are seen as a part of a network that mobilizes on the basis of shared discourses. Social network analysis is utilized to explore the structure and connections of the extreme right. This is followed by

I takt med att världen utvecklas med nya tekniska framsteg ökar mängden konsumtion och därmed fortsätter även mängden farligt avfall drastiskt att öka, vilket skapar nya utmaningar för miljön. Vår framtid är helt beroende av om vi väljer att hantera detta komplexa avfall på ett hållbart sätt, eller väljer att försumma vårt ansvar. Trots de betydande framstegen som gjorts till följd av implementeriWith a rapid increase in technological achievements and consequently consumption, the amount of toxic waste continues to expand drastically, creating new environmental challenges. Our future depends on if we manage this com- plex waste in a sustainable way or choose to neglect the issue. Despite the significant progress made from implementing the Basel Convention in 1992, troubling questions regar

This thesis analyses the energy consumption of the Italian and Swedish residential sector during the last two decades. It has two main purposes: (1) to test the Environmental Kuznets Curve (EKC) hypothesis that stipulate a decoupling relation between environmental harm and economic growth and (2) to investigate on four factors that could explain such decoupling relation. The key factors are the ch

The thesis investigates the perceptions about the importance of sustainability issues in the Millennial generation and the connection of the results to sustainability accounting to show how useful it is. The focus is particularly on sustainability as a criterion for job decisions and the extent to which it influences the motivation at work. In addition, differences in perception about age, gender,

With this research I have answered the twofold question of how Cuba played a part in the making of the Universal Declaration of Human Rights, and what differences and similarities that can be found between the Cuban draft of Human Rights versus the final product of the Universal Declaration of Human Rights. Since there is no previous research in this field I have chosen to look at some of the most

Emanating from Putnam’s two-level game theory of international negotiations, the thesis analyse the interplay between the domestic, the supranational and the international level in the European Union, when negotiating the Bra War with China. The thesis expands Putnam’s theory into a three-level game theory in order to better understand the complexity of the European Union. The work concludes five

Introduction: The prehospital emergency care has had a rapid progress in Sweden in terms of technology, treatments and personnel education demands. In the County of Skane there is at least one specialized nurse in every ambulance. Possible misuses of the resources have been acknowledged in several studies. Aim: To investigate the publics´ current opinion, knowledge and expectations of the prehospi
