In this trial we used QualispermTM as an objective method of measuring stallion semen. Samples of semen were analyzed before and after centrifugation. Motility and concentration were statistically analyzed. During the trial all the objective mesaurments were compared to a subjective method. The advantages of QualispermTM compared to older CASA- systems is it´s ability of measuring a greater amount of spermatozoa while it also grades them into different subpopulations. These subpopulations have different qualities that decides their capacity of fertilization. The results showed that this objective method might be used practically. Although, there are still some disadvantages, such as high costs and the necessarity of accurat training of the handler. If it´s possible to prove further relevant results that also are statistically correct, this could prove the usefulness of QualispermTM as an objective measurment method in the daily work at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work for an improved horse breeding in Sweden, improving both in quality and economically..

It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.

The aim of this study is to evaluate an alternative projection of the Medial Coronoid Process (MCP) of the canine elbow joint. The projection (Di35M-PrLO) was, to my knowledge, first mentioned in an article by Haudiquet et al in 2002. In that article the projection was tested in vitro, and a good sensitivity was showed for the Medial Coronoid Process. The projection might be helpful in cases of suspected Fragmented Coronoid Process (FCP) . This study is divided into three parts. The first part is an in-vivo test of the projection, including technique and subjective evaluation of the outlining of the MCP.

Various problems with nail disorders have been noticed in the Swedish population of Giant Schnauzer, but the frequencies of these problems are unknown. This could be due to the fact that bad nail quality has several differential diagnoses and lack of diagnostic criteria and diagnostic codes for nail disorders. The main purpose of this study is to review different types of claw defects and diseases of the nail bed in dogs, and to classify and evaluate the proportions in the Swedish Giant Schnauzer population. The nail is a specialized part of the skin. The quick will strengthen and protect the third phalang against the surrounding.

The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.

Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.

The aim of this study is to describe how a theme about vitamins and analytical chemistry can be planed and implemented in a summer research school managed by AstraZeneca. The description of the theme is intended to be used as an instructor?s guide to upcoming summers-research-schools with the same theme. The students, which participated in the summer school of 2007, went to upper secondary school. During the summer school they were going to investigate the content of vitamin C in different fruits and vegetables.

This master's thesis examines information literacy and students in secondary education. The study is framed within a sociocultural perspective of learning and the method used is questionnaires. The major question posed is how and where students seek information. Other questions are if the students critically evaluate and analyse in­formation sources and if teachers and school librarians cooperate with each other in order to help the students with their assignments.The findings indicate that most students regard information seeking as fact-finding or finding the right an­swers to the question. Only one third of students experienced information seeking as seeking and using informa­tion for understanding a topic.

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Hållbara avelsprogram för småbönder med getter och får i Afrika är ett viktigt verktyg för att öka människors välfärd på kontinenten. Historiskt sett har inte alla program tagit hänsyn till böndernas vitala roll i programmens utformning. Därför har det på flera håll i Afrika startats upp s.k. community based breeding programs (CBBP) - avelsprogram som anpassats till lokala förhållanden och engagerar de småskaliga bönderna i avelsstrategierna ? och ett antal har visats vara framgångsrika. Denna uppsats presenterar uppbyggnaden av CBBP och beskriver två NGO-initierade projekt för att diskutera vilka faktorer som har gjort dem framgångsrika.

En välfungerande bagge är av största vikt för en effektiv och framgångsrik fårproduktion, eftersom man i de allra flesta fall använder sig av naturlig betäckning med en frigående bagge. När man gör en så kallad breeding soundness evaluation för att utvärdera baggars potentiella reproduktionsförmåga ingår flera olika moment i undersökningen, bland annat pungomkretsmätning och palpation av könsorganen. Dessa undersökningar görs för att upptäcka eventuella sjukliga förändringar i baggens könsorgan och för att kunna välja bort avelsbaggar med en potentiellt sämre reproduktionsförmåga. Mätning av pungomkretsen är ett objektivt och upprepningsbart mått på baggens spermieproducerande förmåga, eftersom det finns ett starkt samband mellan spermieproduktionen i testiklarna och dess omkrets. Dessutom har egenskapen en hög arvbarhet. Baggar från olika fårraser skiljer sig markant åt inte bara vad gäller storlek och vikt utan även vad gäller testiklarnas storlek och form.

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

This thesis was performed as assignment from Fazer Food Services. The aim was to survey which food additives that were present in the products in the quotation list of one of their suppliers to the Education and Nursing segment. The aim also was to perform a theoretical analysis of these food additives and to make recommendations which food additives are acceptable and which should be excluded from the products in the future. The recommendations are not published in this report, for more information Fazer Food Services can be contacted. Food additives which have already been approved are regarded as safe according to the safety evaluation methods available at the time of approval.

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

An industry in distress was the breeding ground for a noted pricing strategy, labeled name-your-price. The industry was the music industry and the pricing strategy bears reminiscence of how medieval buskers earned their living during the dark ages; by letting the customers decide how much the good was worth, embodied by a thrown coin into a hat or similar collector. Translated into the contemporary corporate environment of today, where technical innovations provides access to the intellectual property for free, a few mighty economic actors have once again turned to the strategy were it all started; letting the customer set the price. The hat has been replaced by a box for your credit card number and the live music by a MP3 file, but the similarity is striking. The business model have been applied in other industries as well with various levels of success, thus the purpose of this thesis is to set up a framework for where the name-your-price strategy is applicable.
