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

As widely accepted, innovations are of great importance for regional and national economic growth and competitiveness. Innovation Union is one of flagship targets of European Union Horizon 2020 initiative. However, to understand innovation is still challenging, give its complicated nature; moreover, among factors within policy influence, which variable could help facilitate innovation is also inco

Abstract Author: Lena Källström Title: “Conversations about suffering in social work” (Translated title) Supervisor: Christina Erneling Assessor: The aim of this thesis is to investigate how social workers conceptualise, name, relate to and understand the suffering s/he encounters when meeting clients, both from the perspective of self and the other. The study investigates the view of the indiv

The reality in terms of operational competence has changed. The past tradition of assessing procedural compliance of the individual Air Traffic Controller is today challenged in a dynamic and intractable socio-technical system like Air Traffic Management. Changes in technology and complex system interdependencies, call for an enhanced understanding of the interaction and coupling between the human

Tracking activities have lately been very popular in smartphones, which requires that the devices are able to classify activities correctly. Since this type of devices has limitations in both power consumption and computational performance, it is important to keep these factors to a minimum. Therefore, the low cost of the accelerometer sensor is a good platform to build a classification on. Althou

This study investigated the “relationship between tree species composition and phenology extracted from satellite data in Swedish forests”. The proposed method investigated in this study aims at mapping the fractional composition of deciduous/coniferous tree species and also the fractional composition of Norway spruce (Picea abies) and several pine (Pinus sp.). The fractions can then be used to cl

Forests are today recognised as vital for ensuring a sustainable world and today’s initiatives to save them address everything from actual resource use to fictitious agendas such as carbon sequestration. Forests have become embedded in a “fog of greening”, and in this process local forest become global spaces for saving the world. The fog of greening is dislocated from the ground but has both mate
