Effects of two different light programs on milk yield, prolactin, IGF-1 and sleep in dairy cows
The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.
Revisionsutskott i svenska aktiebolag: En statistisk analys
The recent development in several countries? legislation and best practice recommendations in relation to corporate governance in general and audit committees in particular have affected Swedish listed corporations in the form of the Swedish Corporate Governance Code and the coming EU-directive. This paper aims to discover what factors affected Swedish listed companies to form audit committees when this was entirely voluntary. We collected data from the annual reports of 121 Swedish listed companies and formed eleven hypotheses as to what factors we believed affected the voluntary formation of audit committees based on Agency Theory, economies of scale and circumstances specific to the Swedish environment. We then analyzed the data through the use of a multivariate logistic regression model.
Partiet som utflöde av samhället : En argumentationsanalys av det nyuppkomna partiet Feministiskt Initiativ
This thesis is a study of Parties as an outflow of societal changes where the aim has been to find out how parties are affected by societal changes and how they justify to new party formation. This is done by using a theory called Parties as an outflow of societal changes which is a theory developed by Swedish researchers in Political Science. To confirm the theory it is necessary to do an argumentation analysis of one external developed party?s electoral program. In this case the party selected is Feminist Initiative which brings a different view on how the society of Sweden should look like.Selected parts of the argumentative analysis will be examined with the purpose to give a perspective on how Feminist Initiative values the changes in society and how they describe their role as a new party.The main question of this study is; Are new parties an outflow of societal changes? The basic arguments includes that along with societal changes in Western Europe also changes the view of a representative democracy in which political parties play a central role.
Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål
This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Musikens innebörd och påverkan i elevers skolgång : En studie om hur musiken betraktas och används av elever och lärare i årskurs 8 och 9.
I have been using qualitative interviews to explore music's influence in school from a learning perspective, community perspective and identity-building perspective. I have visited two classes at two different schools to do these interviews with ten informants, both students and teachers. My interview questions were almost the same for both students and teachers, but differed in wording. My research is based on the informants? answers and relevant sources such as literary books, curricula and the Internet.After fieldwork was completed, I transcribed the interviews to further analyze them according to relevant theories, such as Bergman (2009) and Antal Lundström (1996).
Vilka blir effekterna vid införandet av BSC i en stor respektive en liten kommun?
How the running and controlling goes, vary on different municipalities, depending how the organization is constructed and what is being prioritised. There exist laws and directives which the businesses have to follow, but beyond this the organisations are quite free to prioritise and to decide what the best is for the community as a whole unit. The municipality has access to different tools which purpose is to help them running the organization as good as possible, so they can create a well-operated business. This is very important, regarding that the tax money should be spent in an effective way, and be able to do so it is required good and well-functioned system of control.A big change has happened when the instrument BSC (Balanced Scorecard) was introduced in certain municipality. In this essay the focus lies on two municipalities, Vellinge and Kristianstad.
Miljökommunikation i dagspressen : En diskursanalys av hur SvD och DN framställer miljöfrågor
The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. The aim of our thesis is to establish how the environmental public debate as portrayed in the newspaper corresponds to the environmental discussion within the scientific (subject matter expert) field, that is taught by the academic institutions, or if the two materially differ. The environmental communication discourse at the academic institutions advocates ?episodic? formation as the driving force behind transformation of attitudes and behavioral preconceptions. This episodic formation is aimed at incentivizing change by creating intimacy to the incident by linking cause and consequence to the individual citizen instead of to society as a whole.
En studie kring migrationens betydelse för unga somaliers identitetsskapande i Bristol
The Somali community is relatively new in the UK and the majority of Somalis in Bristol are living under poor conditions in deprived areas. According to literature and research relevant for this study ethnic identity seems to be of more importance when threatened by environmental or social changes, such as experiences of migration. Young people are more exposed to such a process of identity construction. The aim for this study was to get a more profound understanding for the significance of migration for young Somali people?s identity formation in Bristol.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :
Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment.
The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.
Barns och ungas livsfrågor och ämnet livskunskap : Existentiella tema på BRIS diskussionsforum
Normal children acquire the necessary social habits without being consciously aware of this, they learn instinctively. (Author?s translation from Swedish to English) (Asperger & Frith, 1998, s. 21) This essay is about people who do not learn to socialize, the social habits, instinctively but through conscious learning. We have interviewed three adults with the diagnosis of Asperger syndrome with the aim to let them tell us about what it means to have a neuropsychiatric disability.
ATP bioluminescence to establish a test procedure for hygiene testing of liners and tubes on farm level : an investigation of the effect of ageing on the hygienic status of rubber liners and tubes
When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.
Konstruktionen av Amerika : Om objektsbildning och hur objektet Amerika skapas i två historieböcker för gymnasiet
The aim of this essay has been to show how the object America is constructed in two of the most used history books in Swedish high school. The theoretical framework used in this paper is based on the post-structural discourse analysis as presented by Michel Foucault. More specifically can be said that Foucault´s theories about formation of objects have been used as a tool to show how the image of America is constructed in the books. Later this paper also discuses which subject positioning the studied books take, also this inspired by Foucault´s theories.The study is presented with long quotes from the studied material to reach a transparency that enables the reader to see which dictums the conclusions are based on. This also makes it easy for the reader to judge whether or not the conclusions are reasonable.
