Kvinnodominerade och mansdominerade yrken - En studie utifrån icke traditionella yrkesval
In this thesis I am going to study how women experience working in a male-dominated occupation and how men experience working in a female-dominated occupation. I have chosen a qualitative method, interviewing four women and four men. By using this method I have gained a deeper understanding of what it is like having a non-traditional occupation. In the background I have looked into the unequal distribution of power between the sexes as well as the entrance of women on the labour-market, where the law of equality has had a major impact on the strive towards a more equal distribution according to sex. The theoretical part includes different theories where gender is focused, both when it comes to the biological differences as well as the segregation of sexes that prevails in society and here socialization heavily influences the choice of a vocation.
Heteronormativets lag : En rättssociologisk studie av rättsligt homosexuellt föräldraskap
This thesis has focused on the construction of homosexual parenthood in Swedish law and preparatory work. The purpose was to describe the norms about legal parenthood and examine if and how homosexual parenthood was included in the normative parenthood. The study was jurisprudential and based on methods such as sociology with a juridical focus and critical discourse analysis of the juridical texts. The theoretical framework was the critical discourse analysis as well as a queer perspective, both influenced by social constructionism and a poststructional theory. The conclusion of the study is that parenthood is described from what is presumably best for the child, which is two parents of different sexes and biological origin.
Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg
In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.
Nötkreatur som övernattar på slakteri : effekter på beteende vid drivning och bedövning
The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.
Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips
Stump biomass is energy rich and stump harvesting for use as fuel become more and more
interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in
Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not
been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of
stump are probably of great importance to make it accepted as fuel. It is therefore rewarding
to carry out an investigation in this area for stump.
This report represents results from a diploma project, which was aimed to develop a fixed bed
reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic
modelling employing Ozawa method and different kinetic models including one-step and
three-pseudo-component models.
Familjehem med konsulentstöd : En kvantitativ studie om konsulentstöd till familjehem
The main aim of this bachelor thesis is to describe through a quantitative study the extent of support received by foster families, their opinion of the support and any areas that might need improvement. The foster families receive foster care support through a private agency. We concentrated on the following areas of support; education, health, contact with the children?s biological relatives and behavioral difficulties. These four areas have, in previous research, shown to be problematic for foster children.
Från pre-human till post-human : Embryots reproduktiva status i skärningspunkten mellan stat och medicin
The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..
Hur upplever fosterfamiljer och biologiska familjer effekten av MTFC- programmet?
Ett stort antal barn är idag placerade i fosterfamilj. Flertalet av dessa barn uppvisar ett asocialt beteende med dåliga sociala relationer. Multidimension Treatment Foster Care (MTFC) är ett program vars mål är att förändra barnets attityd. Det är en öppen vårdinsats där barnet placeras i en utbildad fosterfamilj. En kvalitativ studie genomfördes baserat på nio intervjuer.
Androstenons fysiologiska roll hos grisar
It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.
Bok- och grankonkurrens i Sydsverige - markegenskaper och naturlig föryngring :
In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.
Investeringsalternativ för gårdsbaserad bioanläggning vid SLU
A Biogas plant in SLU?s (Swedish University of Agricultural Sciences) management sustains to behave in con-nection with the new animal stables at Lövsta. There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others substrates that can arise in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study of different investment scenarios.
Analys av haptoglobin i bovint serum med surface plasmon resonance biosensorteknik :
The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.
Linderödsgrisen : en inventering av populationsstruktur och produktionsnivå
In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.

Skyddet av en camp vid internationella insatser mot komplexa hot
The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.
