Skötsel av älgskadade bestånd :

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

Estimation of heterosis and performance of crossbred Swedish dairy cows

The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases. Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.

Ungdomars attityder till sex

Sexuality has an important role in human life and there are many opinions about how to handle questions about sexuality. The attitudes have change over time and differ between different cultures, gender and age. This study deals with the question about youth attitudes to sex and personal relationships and what impact the education in this filed have on the youth. We have also studied how the education is organized. To get answers to these questions we have performed a questionnaire study among 116 students in grade seven to nine in an elementary school in Western Sweden.

The effect of a lowered light intensity at night on cow traffic and milk yield in automatic milking systems

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

Fritidspedagoger och pedagogisk kvalitet : En studie om fritidspedagogers syn på pedagogisk kvalitet med stora barngrupper

This work is about leisure educators' views on educational quality in large groups of children. School centers will contribute to children's development and learning through meaningful leisure and leisure educators' contribution with a high educational quality. There are a lot of discussions and writings about growing groups of children. How are the leisure education and its quality affected by increasing children's groups? It sparked my interest and therefore I wanted to examine this more closely how it might look in the leisure activities.The aim of this work was to examine leisure educators' perspective on how the educational quality is affected by large groups of children and what is considered of leisure educators' as a high educational quality.To answer my purpose five interviews was made with leisure educators' in different parts of Sweden and also by studying the theoretical foundations and literature for school centers and leisure education.The results of the interviews reveal, among other things, that leisure educators' feel that the large groups of children affects the quality of teaching at many levels.

Drank som proteinkälla till regnbågslax (Onchorhynchus mykiss) :

The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.

Exkursion ? ett lärandetillfälle? : Lärare och elevers uppfattningar om exkursioners betydelse för lärande i ekologi

The main purpose of this study was to obtain insight into what students and teachers think about field trips in ecology and whether they think that fieldtrips result in increase of students? learning.

Jag tvingar mig ta Natur : Kulturellt kapital, strategier och kompromisser inför gymnasievalet i en skola i Husby

This is a study on how a group of ten pupils choose their upper secondary schools (gymnasium). All pupils are ninth graders in a middle school in Husby which is a suburb of Stockholm. Like the big majority of Husby citizens, they all have immigrant backgrounds and their time in Sweden varies; some are born here while others are born abroad and migrated later with their parents. My aim was to understand their upper secondary school choices through own and their parents? "cultural capital".

Marknadsundersökning inom datacenterbranschen : Undersökning av tekniska inköp, med fokuspå kyllösningar

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

Mikrosimulering för analys av Mästergatans förlängning i Enköping

Two of the main approach roads into the city of Enköping are Salavägen and Stockholmsvägen. They are connected to each other through the street Bangårdsgatan in the roundabout Salatullen and crossing Fannakorset, respectively. These crossings are from time to time heavily loaded, which is why the municipality plan for a new street in parallel to Bangårdsgatan. The traffic will then be spread out and is thereby reducing the density. The new street is actually an extension of the existing Mästergatan, a side street to Salavägen, to the east and connecting it to Stockholmsvägen or a street nearby.The purpose of this Master thesis is to show how the new street can be drawn in order to discharge the traffic in the area between the roundabout Salatullen and the crossing Fannakorset.

Hur ska du investera dina PPM-pengar? : En studie om PPM-fondernas historiska avkastning

Purpose: The main purpose of this study is to study the 45 funds, divided into three differentdivisions, then the result will provide a greater understanding of how returns change with ahigher risk.Methodology: The study is based on a quantitative approach. The survey was conducted bygathering raw data from databases and secondary data from literature, printed and electronicsources.Theoretical perspectives: The study is based on the theory: the efficient markethypothesis, which argues that future returns can not be calculated as the market is fullyinformed. The study is therefore studying historical yields.Empirical foundation: Empirical data are acquired from www.morningstar.se, andtherefore also treated on this page. The material is then divided into documents and time axes.Conclusions: The study has shown that high-risk funds give a higher percentage returns thanmedium-and low-risk funds. However, does not imply a higher risk automatically earn ahigher return when the low-risk funds have shown a higher yield than medium-risk funds.

Flexorafiskt tryck på wellpapp

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.
