The ability of dairy cows to survive and the economic importance of this have been in-creasing in dairy cattle breeding lately. Increased longevity contribute to an increased pro-portion of cows that produce milk in more productive lactations and reduces the replace-ment costs together with a good health and fertility. Unfortunately it is often argued that longevity has been decreasing due to a strong selection for production traits in dairy cattle.The aims of this study were to find correlations between different longevity evaluations and between different estimates on longevity and other traits in the Nordic Total Merit (NTM) breeding value. The aim was also to compare different traits for cows of two differ-ent longevity groups.The data were Predicted Breeding Values (PBV) from Nordic HOL and SR bulls and records from Holstein (HOL) and Swedish Red (SR) cows estimated by the Swedish Dairy Association.The three Swedish longevity indexes were very highly correlated (>0.89) and the corre-lations between the Swedish official longevity index and the five Nordic Cattle Genetic Evaluation (NAV) longevity indexes varied between 0.73-0.83.In the sire evaluation part, the traits most negatively correlated with longevity for HOL were dairyness, protein and fat index. In SR, milk, protein, and fat index only had slightly positive correlations with longevity.

When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate (P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

The aim of this study was to describe and analyze the problems caused by students that characterize themselves as highly sensitive. The issue of high sensitivity and other categorizations are fiercely debated in the research. This empirical study was conducted in light of literature about high sensitivity, pedagogies, and interview methods. The students answered questions about what makes them categorize themselves and how they believe that the categorization affects their learning and social development. They also responded to questions about what they consider appropriate measures to improve their situation.

I approach the subject of adult readers of young adult fiction through an analytical framework influenced by Cultural Studies, implicating that young adult fiction is caught up in a system of distinction between popular literature and high literature. I contrast this with theories that suggest that there has been a loosening of this hierarchy and that they now coexist, even borrowing features from one another. I also examine questions of ideology, namely the ideology of mass culture, the ironical attitude and the ideology of populism. I also use Andreas Huyssen?s theory of mass culture as a woman, seeing as popular literature often tends to be categorized with feminine traits.

The aim of this paper is to present a case study that increases the understanding of pooled purchasing between independent companies, but also acknowledges the importance of relationships. While previous research has established the advantages and disadvantages of pooled purchasing, our paper shows that successful relationships can render additional synergies and benefits. At the same time, one must consider the time and resources needed to create successful relationships as well as the resulting interdependencies. These implications are well established within the field of purchasing and network theories. However, the authors believe that these implications need to be more explored in regards to pooled purchasing..

The costs often exceed onehundred percent of the annual salary for the otherwise vacant position. In addition to thedirect costs of employee turnover troubles, things such as work confusion, loss oforganizational memory along with strategic skills can arise. The employee turnover rateof Trygg-Hansa?s outbound department in Växjö is too high according to the officemanager.Purpose: Understand the causes of high employee turnover in a Swedish insurancecompany.Methodology: This thesis consists of an ethnographic study of a Swedish insurancecompany.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

AbstractObjective: The aim of this study was to investigate the statistical properties of a self-assessment instrument for depression, Känsloläge, with regard to validity, reliability and factor structure. Method: The data collection method used for the study was mail questionnaires. The sample consisted of patients who had received treatment for heart failure, arrhythmic disorders or coronary heart disease at a hospital in Uppsala, Sweden. The study population consisted of 53 patients. The self assessment form?s validity was analyzed by measuring the criterion validity.

This report presents the use of questions by both teachers and students in chemistry class. Both students and teachers have been observed during 24 lessons, both theoretical and practical. In addition, interviews have been made with the teachers and the students have answered a questionnaire. The result show that a high number of questions are asked, more than one per minute and that both teachers and students ask the same amount of questions. This contradicts earlier findings were teachers questions dominate.

The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records.

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.
