Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

Denna uppsatts består av en kvantitative enkät studie som genomfördes på två högstadieskolor i mellan Sverige under våren 2012. Syftet med uppsatsen är att få en inblick i vad som ligger bakom elevers val av fritidsaktiviteter och då mer precis val av fysisk aktivitet samt att undersöka skolans, och då främst ämnet idrotts och hälsas, roll i elevernas val av aktivitet. Bakgrunden till rapporten kommer från formuleringarna ur lpo 94 och lgr 11 som betonar att ett syfte med ämnet är att främja Idrott och hälsa ämnets uppgift att främja fysisk aktivitet på fritiden. Vi analyserar tidigare forskning som bland annat har undersökt den störta föreningsidrotten som utgörs i Sverige och vad det kan finnas för faktorer till att ungdomar utför den. Tidigare forskning som används i rapporten är bland annat från venska riksidrottsförbundet och ungdomsstyrelsens rapport om unga och föreningsidrotten.

Title: Teaching environment and teachers. A study of how music education philosophies influence instrumental teaching and learning at a community music school. Question of the research: Which Music philosophical ideas can be traced in the instrumental teaching of a community music school? Two teachers and their students have been videotaped. Data from the tapes and from interviews with the teachers and students have been analyzed by means of a category system, which grew out of the theoretical overview.

Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The  purpose  of  this  paper  is  to  highlight  bicycle  accidents  at  intersections  and  to  suggest improvements  in three accident-prone junctions  in Stockholm.  This is  achieved  by  the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.

The aim of this thesis is to examine how different kinds of information seekers are evaluating information quality in the information flow online. To address the problem stated, qualitative interviews were carried out with a librarian as a reference person and a group consisting of journalists and scientists. The result of the study implies that the reference person is well aware of the strategies employed by her in the search process. However, the respondents are not aware of the strategies they are actually using. An explanation is the respondents lack of education in information seeking.

The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservationbecause of its geological values with many unique landforms. Many of these landforms indicatethat the deglaciation process in the area was very complex. However, the deglaciation process inthe area has not previously been fully understood. The aim is to add to the knowledge of theevents that took place during the last deglaciation. To do this, the glaciofluvial landforms in thearea were mapped by studying aerial photographs with a Wild Aviopreter and a five-day fieldinventory of key areas for the interpretation.

This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.

A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.

The future climate of Sweden is expected to become warmer in the future. This would be beneficial for vineyards and may lead to a greater area being allocated for wine production. The environmental impact concerning eutrophication from Swedish vineyards has not been evaluated before. In this study nutrient balances are constructed for four Swedish vineyards with the goal to estimate the out and in flows of nutrient in the systems for the year 2010. Interviews with focus on farming practices undertaken during the year are conducted with the farmers.

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

This is a qualitative study with a reflexive approach. The aim of this masters thesis is to describe how the internal information is managed in Borås Theatre and Borås Public Library related to the internal flow of information within the organisations according to descriptions of different units, staff and work tasks. Ten qualitative semi-structured interviews with employees at the Theatre and the Library have been conducted. The organisations have been studied separately. The interviews are presented according to six categories presented in the theory chapter as a result of the study.

The most important conclusion of this study is that the negotiations between the parties ends when conflicts arise from property owners, and with this the time will be extended and be more costly. During the study it has been shown that good communication is the key to an effective and successful negotiation between the parties.The purpose of this study is to investigate how the practical procedure under expropriation is in relation to the legal text, in other words, describe and analyze the procedure for expropriation under current rules but also to explain how it operated in practice. This is to get a picture of how the process works and what effects it receives.Three methods were used for the study. A literature review for understanding how expropriation relates according to the law. A case study from an ongoing expropriation in Sundsvall municipality, and an interview with seven affected interested parties from the expropriation.Reviewed literature describes how the application of the Expropriation Act must go to as well as other research on the topic.

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

This master?s thesis investigates in which ways students seek out and access their textbooks and how they use their university?s library in this process. Data is collected through interviews from six students several semesters into their studies at the University of Stockholm. For the interviews two students each were selected from the fields of law, economics and humanities. The empirical findings were analyzed using T.D Wilson?s model of information behavior (1997).

Clarice Lispectors is one of Latin Americas most famous writers, and she wrote a number of books during her lifetime. Her novel Stream of Life (Água viva), which came out in 1973 and was translated into Swedish in 2007, is considered to be one of Lispectors most difficult texts to read. It consists of several fragments put together into one text; however the text has no traditional narrative or structure. It is the flow of moments that moves the text forward, as it is written down by the protagonist in the book.The primary aim of this essay is to examine how the protagonist in Stream of Life through different means, as the moment, the description, the word and the variations, creates an active participation in the formation of its identity. I will discuss the moment and its act of constructing the book?s circular structure, which is of importance.
