The goal and ambition of this thesis has been to investigate a topic that could lead to a possible solution to the environmental crisis we are witnesses of. Replacement of fossil fuels is an essential step towards a renewable society that needs to be taken. This thesis will investigate one of those possible solutions, production of a biofuel from a renewable source. A large amount of research with
Stamceller är en typ av celler som ännu inte har specialiserat sig till en bestämd roll i kroppen, utan kan omvandlas till vilken celltyp som helst. Detta gör dem mycket användbara vid läkning av exempelvis hjärnskador, eftersom vuxna nervceller inte återbildas. Tyvärr är stamceller svåra att utvinna, och kommer de från en annan individ riskerar de dessutom att stötas bort av mottagaren, som vid bWe define a mathematical method that, given the form of an interaction network, defines an energy as a function of the state of the network. When combined with a suitable entropy, it yields a free energy that gives rise to the dynamics of the network, allowing solutions and optimal paths to be efficiently found. This is done primarily with the gene regulatory networks governing cell reprogramming
Syftet med mitt arbete har varit att kartlägga dynamiken för inlandsisen i undersökningsområdet på och sydväst om Söderåsen i Skåne från senaste glaciationsmaximum (LGM) till deglaciationen. Mest fokus har lagts på att identifiera och tolka glaciala landformer från höjdmodeller och jordartskartor. Området omfattar Söder-åsen, Helsingborgsryggen och Ängelholmssänkan. Dessa tre områden har olika geoThe purpose of this degree project has been to review how the Weichselian ice sheet dynamics have developed from the last glacial maximum (LGM) until the deglaciation in my examination area, on and southwest of Söderåsen in Scania Sweden. Most work has been put into the interpretations of different landforms from LiDAR based elevation models and soil maps. The area includes Söderåsen, the Helsingb
Populärvetenskaplig sammanfattning - Automatiskt ingångssystem med hjälp av flerobjektsspårning Tänk om de dörrar du passerar vet vart du är på väg? Med en kamera och bildbehandling visar vi att man kan spåra människor och förutse deras rörelse. Detta ger stora energibesparingar och ökad komfort. Automatiska dörrar är något de flesta kommer i kontakt med dagligen, på jobbet, gymmet eller i matvIn this thesis we employ computer vision methods in order to extend and improve the functionality of automatic doors. This thesis is based around the implementation of a door entrance system which uses information from detected pedestrians to make qualified decisions regarding door activation. This can lead to a reduced amount of unnecessary openings which will reduce the energy consumption of bui
Syftet med denna studie är att undersöka hur sångpedagoger praktiskt arbetar med interpretation, samt om det finns någon koppling mellan deras arbete med interpretation i förhållande till genrer. Det är en kvalitativ studie som är baserad på intervjuer med tre sångpedagoger samt observationer av deras respektive lektionsarbete. Resultatet visar att sångpedagogerna arbetar och ser på interpretationThe purpose of this study is to investigate how vocal teachers work with interpretation, and whether there is any connection between their work with interpretation in relation to genres. It is a qualitative study based on interviews with three vocal teachers as well as observations of their respective singing lessons. The result shows that the vocal teachers work with, and define interpretation in
This thesis is a critical discourse analysis of the development of job advertisements regarding gender coding. The time span is between 2007 and 2016/2017 and the material for the analysis is 40 advertisments towards medical secretaries and carpenters. This selection has been made because these professions are the percentage most female- and male-intesive occupations in Sweden. The study is based
Compassion fatigue kan drabba yrkesverksamma inom vårdgivande yrken som arbetar med traumapatienter. Symtomen på compassion fatigue är både fysiska, emotionella och arbetsrelaterade och innefattar bland annat empatisk utmattning och reducerad förmåga att bära patienters lidande. Dessa egenskaper påverkar psykologer inom vården. Psykologer är en yrkesgrupp vars sjukskrivningsstatistik har ökat undeCompassion fatigue can affect professionals in health care who work with trauma patients. The symptoms of compassion fatigue are physical, emotional and work- related and include, inter alia, empathic fatigue and reduced ability to carry the suffering of the patients. These qualities affect psychologists in health care. Psychologists are a professional group whose sick leave statistics has increas
Emulsion is a novel technique to deliver fats and fat soluble compounds in food, pharmaceuticals and cosmetic products. Different emulsifiers are often used to stabilize the emulsions. Chemically modified quinoa starch granule has taken research importance as an emulsifier in last decade. Chemically modified starch stabilized emulsions are now also been dehydrated to facilitate its use multidimens
In this paper, we develop a new but also under-researched measure for firms’ hedging practice: maturity. Comparison between the outputs of two sets of Tobit model using hedge ratio and maturity respectively shows that the costs of financial distress hypothesis and the financing costs hypothesis are partially supported by both hedge ratio and maturity. Besides, the economies of scale hypothesis rec
Reclaim the Streets is a study of exploitation and parametrically driven urban planning. The land I propose to be exploited are the buffer zones that since the 1950s started being reserved along major roads, and since mostly have been left untouched. The wide passages have created barriers in the city that affect pedestrians by increasing travel times and creating unsafe places. My intention is to
Background: while access to safe water in Uganda increased between the early 1990s and 2010, current studies are showing that many safe water sources are not being properly maintained and so end up being abandoned. Since the maintenance of safe water sources is under the jurisdiction of water user committees (WUCs), this study seeks to measure the ability of water user committees in mitigating a d
As part of the development of a process for production of a lignin-rich oil that can serve as a renewable feedstock to existing petroleum refineries, hydrogen assisted depolymerization of lignin in filtered black liquor has been investigated. This process offers the possibility to reduce fossil emissions from transportation by utilization of the largest renewable carbon resource in Sweden, namely
Luminiscensdatering är ett viktigt verktyg inom geologin för att tidsbestämma geologiska avsättningsprocesser i jordens historia. Grundförutsättningen för en korrekt datering är att luminiscenssignalen genererad från ett mineral nollställs vid kontakt med solljus. Vid insamling och preparering av provmaterial är det därför av yttersta vikt att ingen ljusexponering inträffar som eventuellt nollstälLuminescence dating provides an important tool in geology to reconstruct geological depositions events in the Earth’s past. The basic assumption for a reliable dating is that luminescence generated from minerals resets at the time when it was last exposed to sunlight. The accuracy and precision of luminescence dating is therefore strongly dependant on preparation of the sediment to be in dark cond
Agriculture is necessary for providing nutrition to a growing global population. However, many unsustainable agricultural practices contribute to climate change, cause local pollution and disrupt natural biological and nutrient cycles. Conservation agriculture (CA) is one of the many practices that have been proposed to meet the challenge of sustainable agricultural production. CA aims to restore
Our world is experiencing accelerated ecological destruction and social injustices on different scales and multiple levels. Unchecked economic growth has been criticised as causing this since the 1970s, but the dominant sustainable development paradigm has perpetuated the belief that economic growth and environmental protection can go hand-in-hand. In response degrowth has emerged in the last deca
Kan svenska rapsrester bli ett nytt alternativ till sojafärs? Allt eftersom jordens befolkning ökar utnyttjas större delar av jordens yta till åkermark. Forskningen visar tydligt att växtbaserade livsmedel har mindre miljöpåverkan än animaliska produkter. Rapsfrökaka är en restprodukt från rapsoljeproduktionen med högt proteininnehåll som har lovande egenskaper för att bilda ett nytt växtbaserat lThe combination of a growing global population and a limiting amount of farmland creates a need for new innovative food products to achieve a global sustainable development and a healthy population. Rapeseed press cake is a low-cost by-product of rapeseed oil production and is very high in protein and fiber. The rapeseed protein contains high concentrations of S-amino acids as methionine and cyste
