Mikrotexturer är mikrometerstora avtryck på kvartskornens ytor samt på korn med andra mineralogiska egenskaper. Kvartskorn, som förekommer i de flesta sedimentära miljöer, innehåller mikrotexturer som undersöks särskilt på grund av kvartsmineralets unika mineralogiska egenskaper som möjliggör bevarandet av mikrotexturer genom olika miljöer. I denna studien är mikrotexturer en viktig källa för att Microtextures are micrometer-sized imprints on the surfaces of quartz grains and on grains with other mineralogical compositions. Quartz grains, which occur in most sedimentary environments, contain microtextures which are especially studied due to quartz unique mineralogical properties allowing for preservation of microtex-tures through different environments. In this study, microtextures are an

Visionaries around the world are advocating for a shorter working week, and there is a reason behind it. Long working hours have been shown to impede productivity while a reduction in working hours increases work-life balance. Future generations’ economic and environmental sustainability may furthermore benefit from a shorter working week. Through a redistribution of working hours, equality and em

The present quantitative research focuses on studying the effect of uncertainty in online information search related mainly to travel planning. The main emphasis is in the individual and combined effect of these variables towards different demographic segments of international travelers. In order to do so it draws insights from Uncertainty avoidance (Hofstede, 2001) and information foraging theory

This master thesis contains an overview of existing additive manufacturing methods and considers possible new methods. The purpose being to develop a method for additive manufacturing that can create 3D objects with composite material and/or out of metal. Further this method should work on a low cost additive manufacturing machine. A development process is used in order to select an appropriate me

This research is a theoretical contribution to CCT and existing literature on ownership, investigating whether ownership has become an out-dated ideal in consumer culture. We explore how Millennials negotiate issues of ownership and sharing in the context of collaborative consumption. Consequently, the study provides insights on new consumption forms, and more specifically swapping and access-base

In surveillance applications one thing to consider is how much of a scene one can cover with a camera. One way to augment this is to take images with overlap and blend them, creating a new image with bigger field of view and thereby increase the scene coverage. In this thesis work we have been looking at how one can create panorama images with a pan-tilt-camera and how fast it can be done. We chos

We study the predictability of sentiment on stock return of the Hong Kong market. We measure sentiment by forming composite sentiment indices from several proxies using principal component analysis and the partial least square method. We find that sentiment measures using either method have similar in-sample forecasting power but the one formed by using partial least square method has better out-o

The aim of this study was to get a deeper understanding of how Unit Heads within the Swedish social services view the work environment of social workers in social welfare offices. The study was based on six social services Unit Heads from the southern part of Sweden. Semi structured interviews were used to examine what different factors affect the social workers in social welfare offices work envi

Medelpensioneringsåldern i Sverige har länge varit mer eller mindre konstant trots att medellivslängden har ökat. Syftet med denna studie är att undersöka huruvida det finns en optimal pensionsålder när den förväntade återstående livslängden är en annan än den Pensionsmyndigheten förutsatt och om detta kan förklara den konstanta medelpensioneringsåldern. Studien tillämpar en kvantitativ metod och

Idag använder sig en majoritet av alla svenska grund- och gymnasieskolor av en lärplattform. En lärplattform är mjukvara som stödjer både det administrativa och pedagogiska arbetet och används bland annat till kommunikation, bedömning och till att tillhandahålla material i undervisningen. Uppsatsen kopplar samman lärares upplevelser av dessa lärplattformar till teorier gällande användaracceptans.

The aim of this study is to investigate the hotel attributes that affect selection by football fans when travelling away from home to participate in a sport event. Attributes that identified in previous researches were segmented into five major sets and the most common and relevant to the purposes of this study were chosen to form the questionnaire. Questionnaires were distributed through online c

Knowledge about women’s participation in combat roles, yet alone in national armed forces in the Arab countries is very limited. Although more women are acquiring access to combat roles worldwide, most scholarly investigations have focused on servicewomen in the West. As the United Arab Emirates (UAE) is emerging as a rampant participant in international relations and it contributes forces to glob

Detta examensarbete utfördes i samarbete med LVI, Low Vision International AB för att utveckla ett nytt arbetsplatsanpassat system för personer med nedsatt syn. Företaget är specialiserat på att utveckla, producera och sälja olika typer av tekniska synhjälpmedel i Sverige, Europa och USA. De hjälpmedel som utvecklas på LVI består till största del av förstorande läskameror som finns i olika utföranThis thesis objective was to design a workplace integrated system for people with visual impairment for LVI, Low Vison International. The system is in the same category of video magnifiers as the company’s other products and it was desired from the company that the product maintained the overall LVI design language. Initially a pre-study was performed that consisted of identifying the user, analy

With the use of arms trade data spanning the time period between 1992 and 2010, this thesis sets out to study what influence joining NATO has on a country’s volume of arms export and its probability of exporting arms. An assessment is also made of how NATO members trade arms. The data is estimated with a set of different gravity models and by using linear regressions evaluating volume and logistic

The sediment composition of drumlins in the Åsnen area in Småland, south Sweden is poorly studied. Excavations are being planned with intention to study the internal architecture and composition of these drumlins. As a preliminary investigation this thesis was done to determine the sediment depths in the tail of a drumlin at Rörvik gård, situated on Vemboö in Lake Åsnen. To determine the sediment

Bakgrund: Amyotrofisk Lateralskleros (ALS) är en dödlig neurodegenerativ sjukdom. Destruktion av motorneuron leder till att ALS-patienterna blir helt förlamade, vilket medför en stor påverkan i patienternas liv. Syfte: Belysa patienters upplevelse av att leva med ALS, genom att beskriva hur patienters liv och livskvalitet påverkas av sjukdomen. Metod: Litteraturstudie med integrerad analys. Result

Mykorrhiza motverkar läckage av kväve Tillgången på kväve (N) begränsar tillväxt i nästan alla land-ekosystem. Därför förväntas ekosystem optimeras för att hushålla med denna resurs. Förbränning av fossila bränslen och industriell tillverkning har nyligen fördubblat tillgången på N. Jag har undersökt hur träd ingår partnerskap med svampar för att effektivisera sitt upptag av N, och hur deras relaEctomycorrhizal fungi (EMF) mediate nutrient exchange between trees and soil in coniferous forests. Nitrogen (N) currently limits net primary productivity (NPP) in many terrestrial ecosystems but N deposition may alleviate this limitation, inducing limitation of phosphorous (P) instead. Studies have shown reductions in production of EMF mycelia (EMM) when trees are alleviated limitation of N, unle

The purpose of this study was to examine how personnel working with unaccompanied refugee children at homes for care or residence highlights individualized support in their work, and to analyze opportunities and obstacles within this work. Qualitative interviews were performed with five personnel, from three different homes for care or residence, working with unaccompanied refugee children. The co
