Quantification of sleep in dairy cows in three different stages of lactation
The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.
Motivation in Knowledge Intensive Firms - More art than science
Workers are more demanding than ever and stay a shorter amount of time within the same organization. For this reason we wanted to look further into how organizations work with motivation in order to create success in Knowledge Intensive Firms. The complexity of knowledge workers formed the base for our interest within the subject. The purpose of our thesis is to reflect upon what is written about the motivational effects of recruitment and reward strategies in Knowledge Intensive Firms. Further our essay is based on an abductive advocacy.
Undersökningsmetodik för klorerade lösningsmedel i marken
Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.
Oproblematiska problem? : Gymnasieelevers uppfattningar om och upplevelser av jämställdhet
The aim of this master thesis is to examine high school students? understandings and experiences of gender equality and to critically study the formulations and the basis of the project from Save the Children Sweden which are the basis for this master thesis. By using critical discourse analysis and gender theories the formulations and basis of the project and the interviews has been analyzed. The analysis of the project showed neglect for intersectional perspectives and taken for granted hidden opinions about masculinities and femininities. The interviews have been conducted with four high school students, and the students felt that they attend schools which are equal between genders.
Deltidsarbetandes företrädesrätt till högre sysselsättningsgrad
During the 20th century Sweden faced an increased proportion of workers registered as part-time unemployed, especially in the care sector. However, due to many valuable efforts, aimed at solving the problem of part time unemployment and political decisions, the number of people who are part-time unemployed has declined since the late 20th century. We have investigated part-time workers preferential right to extending their working hours. According to Section 25 a of the Employment Protection Act, part-time employees who have submitted an interest in increasing their working hours has a preferential right to increased working hours, with the assumptions that full-time employment with the employer will meet a labor need that the employee has sufficient qualifications for.Qualitative interviews have given us information about how Karlstad Community and a private care company deal with part-time unemployment and their workers preferential right to extending their working hours. We have found that people who work for Karlstad Community have an opportunity to choose their number of workings hours, thanks to a political decision made in Karlstad Community, aimed at solving the part time unemployment in the care sector.
Osäkerhet i investerares avkastningsbedömning av kommersiella fastigheter. - Osäkerheter i bedömningen av drift- och underhållskostnader?
This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
The contentious nature of war : an analysis of military theorists
The purpose of this essay is to investigate and assess, with Clausewitz?s theory as thebackground, how different military theorists interpret and relate to the nature of war.This essay illustrates the state of research into Clausewitz?s philosophical influences.Clausewitz?s theory of the nature of war is subjected to a qualitative text analysis that is followedby a critique of other military theorists interpretations of his theory. Subsequently a descriptive,comparative qualitative text analysis is performed where the factors identified by Clausewitz asbeing part of the nature of war (?rational thought?, ?passion? and ?chance?) are used as a meansto interpret and assess how other military theorists relate to Clausewitz theory.

Scintigrafisk undersökning av esofagusmotilitet hos häst :
Scintigraphic examination of the esophagus has for some time been the method of choice for the study of motility dysfunction in humans. The method has not yet been described for horses hence the lack of reference values for passage time for a bolus through the esophagus in healthy subjects. The purposes of this study were to measure passage velocity and time for a bolus to pass through the esophagus in healthy subjects, as well as to evaluate the reproducibility of the method. Eight warm-blooded trotters were used in the study. The horses were sedated with a low dose of Acepromazine prior to onset of the study.
Luftprovtagning samt analys av mono- och diisocyanater
When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.
"Muslimerna som sätter världen i brand" : En kvalitativ studie om hur muslimer representeras i svensk press
This study concerns how Muslims are portrayed in a choice of twelve news articles from Swedish dailies and tabloid newspapers on the aftermath of the film Innocence of Muslims published on YouTube. All articles are distributed in the newspapers Aftonbladet, Expressen, Dagens Nyheter and Svenska Dagbladet in the period of September 11th, 2012 until September 30th, 2012.For this study, a qualitative text analysis has been embraced and focus has been on van Dijk?s Critical discourse analysis to the texts, with additional features from semiotics applied on the images.The theories consist of Critical discourse analysis, hegemony, ideology and power, postcolonialism and stereotyping.In the qualitative content analysis, concrete examples from the articles are retrieved and commented. These have been divided into various themes, which are trends that the authors have been able to distinguish in the analysis.The result shows that Muslims in the analyzed newspapers are portrayed as the others, unimportant and extremely religious, in a negative manner rather than a positive. Moreover the press has tendencies to generalize Muslims as a group.
Vad är viktigast i staden? : Utveckling av ett lokaliseringsverktyg för stadsplanering
This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.
Bibliotek i kristider: Perioden 1930-1945
In 1930 a new library reform came into force, which in reality was the beginning of the modern Swedish library. The purpose of this reform was to take measures to promote efficiency, for example to increase library co-operation. The Government grants were at the same time raised considerably. However, as early as in 1930, but especially the following year, the depression hit Sweden. The Government reduced the grants until the first half of 1936.
Unga vuxna med unilateral läpp-, käk- och gomspalt ? perceptuell bedömning och självskattning av tal och kommunikation
The purpose of this study was to investigate how young adults withunilateral cleft lip and palate assess their own speech and communication,and to let speech and language pathologists make a perceptual analysis ofthese individuals? speech at the age of 19 years. An additional aim was toexamine the relationship between these two different ways of evaluation.Data was collected through perceptual analysis from audio recordings and byusing a self-report questionnaire based on the ICF-structure (InternationalClassification of Function, disability and health). Altogether, 33 peopleparticipated. One third of the participants had no speech deficiencies.
Synen på hemlöshet : En diskursanalys av hemlöshetsarbetet i Norrköpings kommun
The aim of this paper is to see how the local authorities in Norrköping create a way to look at homelessness. This aim is examined with the help of the central questions: How does the municipality describe homelessness as a phenomenon? What causes to homelessness can be seen in the texts?
