Från 7-Eleven till vegetarisk KRAV-märkt buffé : Den förändrade organisationen av skolmåltider och dess relation till skolornas symboliska tillgångar
The purpose of this study is to examine how school meals are organized in a selection of Stockholm's secondary schools and to examine the relationship between school meals and the different parameters that indicate each school's symbolic capital and educational capital. By looking at the statistics from each school on the basis of the final grade average, percentage of pupils with foreign background and gender, I examine whether it is possible to see a relationship between how schools organize meals and which pupils attend the school. In my study, I systematically went through each school's website and tried to identify how school meals at each school are organized. To increase the validity of the study, I have also conducted a questionnaire survey by mail addressed to school principals. In order to analyse and understand my results and put them in relation to my current knowledge about the schools in my sample, I am using Bourdieu's theoretical tools that a given aid, both in methodological and analytical purpose. Based on Bourdieu's theories of symbolic capital, cultural capital and educational capital, I can understand and analyse school meals are organized and focused as part of schools' symbolic assets in competition with other schools. The first part of the study shows that there are four different organizational models for school meals, fully equipped kitchen and canteen, heating kitchen and canteen, school meals in restaurants and school meal card. In the second part, I have examined the relationship between the type of organization for school meals used and the symbolic resources available at the school. I can conclude from the results that it is difficult to find a correlation between the symbolic resources and the different categories. But even though it is not possible to see all the schools' symbolic assets equally clear, there are still some very telling examples. In many ways, these examples can be seen as polar opposites to each other based on Mikael Palme?s concepts ?goal rational? and ?education oriented? schools..
Population and management models for the Swedish wild boar (Sus scrofa)
The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

Rörelsemönster och golvrenhet på två olika slags spaltgolv i lösdrift för mjölkkor :
About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.
Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
Dekonversion och självuppfattning : En religionspsykologisk studie av dekonvertiters berättelser
This study focuses on aspects of cult experiences, given by deconverted formermembers of closed religious movements. Their testimonies were published inbooks or interviews. The aims of the study were to understand the interactionbetween the religious group and its members, living in high tension towardsmainstream society and their testimonies of altered self-esteem during attraction,membership, deconversion and defection. The purpose was to understand how aperson´s self-esteem is affected by inner mechanisms of closed religiousmovements and how these experiences affects a persons identity. Another aspectwas whether there might be differences in altered self-esteem, between those whoenlisted as adults, and those who were born into the closed religious contexts.Social Identity Theory, Sigmund Freud´s and Carl Rogers models of personal egowere used as models of interpretations.
?Hänga och må bra eller ta sin bok och dra?. Bilden av biblioteket PUNKTmedis efter ungdomsanpassningen.
The aim of this paper is to examine the youth library PUNKTmedis' work methods to adapt itself to the youth. Improved communication with this user group is the starting point for the new work methods. We have chosen to view the increased cooperation between the library and the youth as an adjustment to market demands. We have noticed the possible existence of an antagonism between on the one hand the traditional role of the public library of adult education and on the other hand an adjustment to the market demands. Adult education and the adjustment to market demands is seen as contributing to the image of PUNKTmedis.
Establishment and evaluation of a Barley starch isolation method with focus on representability
The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.
Motivation ur ett elevperspektiv : En studie om vilka faktorer som har betydelse för elevers motivation
AbstractThis study deals with motivation as an overall concept, from a student perspective. It encompasses factors that could directly affect students and their positive or negative motivation, concepts such as relationships, communication, expectations and interactions and their importance to my informants.The study also discusses certain theories to show the different ways of defining motivation, specifically in relation to my informants and their and my conclusions. My ambition is to establish the importance of the concepts mentioned above, as well as perspective changes to the enhancement of the performance standards of a good teacher.The purpose of this work is to describe, understand and clarify the external and internal factors that affect motivation. In order to achieve this purpose, I chose to use a method of qualitative interviews with three students, with different backgrounds, schools and conditions but with a lack of motivation as a unifying characteristic. The research questions were as follows:What factors influence students' motivation? What impact do achievement targets have in relation to the pupils? own motivation to learn?How important are teachers' expectations for the individual student's motivation?Within this study sub-concepts such as importance of expectations, relationships, and significant others are, according to my analysis, of great importance.
Patogenes för prostatacarcinom hos hund : en jämförelse med människan
This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.
Mätprocessen kring propelleraxlar
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.
Bostadsförsörjning planlagd?
This thesis seeks to investigate the relationship between municipal policy for housing supply and the planning of new housing in Sweden. Through a case study of Göteborg municipality and a comparative content analysis of Göteborgs policy for housing supply and a number of plans featuring housing the analysis seeks to investigate the effect of policy for housing supply as a tool for securing the demand for housing in the Swedish municipalities. The thesis also seeks to discuss its findings using theory concerning the implementation of policy and the general planning situation for Swedish municipalities today. The result of the analysis shows that most plans fail to regulate most of the content suggested in the policy for housing supply, particularly regarding aspects such as pricing, type of housing and type of ownership. The result also points towards a relationship regarding the prevalence of municipal land contracts and compatibility to policy for housing supply as well as a connection between how extensive the plans are in their proposed land use and their compatibility with policy for housing supply.

Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
