Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.

En traumatisk kris är en reaktion på en yttre händelse och omständighet. Krisen har fyra faser som de drabbade går igenom, där chockfasen är den första och slutar med nyorienteringsfasen. Studien syftar till att utifrån ett emotionssociologiskt perspektiv studera fyra kvinnliga informanters upple-velser och känslor under och efter en traumatisk kris, som består av kata-strof, dödsfall och sjukdomsdiagnos. Studien söker även svar på hur infor-manternas omgivning, i form av familj och vänner, har agerat i samband med krisen. Genom kvalitativ metod med intervjuer berättar fyra krisdrab-bade informanter om den händelse som utlöste krisen och hur de hanterade detta.

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

ABSTRACTEssay in Political Science, Advanced Continuation Course, 61-80 credits, by Jonas Nilsson?The democratic islamist? - a study of three islamist movements and their potential role in ademocratization process?Supervisor: Jonas LindeThe purpose of this work has been to explain to what extent islamist movements can be said to bebearers of democratic values and if they have a role to play in future democratization processes. Thepurpose of this work is also to examine the democratic views of the different islamist movements andto compare them with each other in an effort to find a specific islamist definition of democracy.The essay is a qualitative analysis of the Muslim Brotherhood in Egypt, Front Islamique du Salut inAlgeria and Hezbollah in Lebanon. The analytical framework is based on the political institutionsincluded in Robert A. Dahl polyarchial democracy.

Sustainable development has become the ideology of the twentieth first century. As an important concept and as a framework of political action, sustainable development can at this point be considered as the very symbol of a paradigm in the international debate over environmental issues and the threats of climate change. But what does the concept of sustainability actually suggest? This thesis uses discourse analysis in order to examine the Swedish learning for sustainable development as to three different discourses on the national arena: the government and the municipals of Piteå and Växjö respectively. When the study foremost concerns official policy documents that contain associations with the study area, the methodology used takes into consideration both language, signs, metaphors and so called story lines.

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

Background The Shetland Sheepdog is a popular breed of dogs in Sweden. The breed is mostly used as a companion dog and is also popular within certain dog sports such as agility. The Shetland Sheepdog is not included in any breeding programs regarding joint health. The animal insurance company, Agria had recently informed the Swedish Shetland Sheepdog Club (SSSK) that they had noted an increasing number of arthritis in the elbow joints, therefore they wanted to exclude elbow joints from the insurance until SSSK started a breeding program against elbow dysplasia. After the start of this study Agria withdrew their demand, but the study went on as planned. Aims of this study The aims of this study was to investigate if there is any data that may show if there is a larger or smaller reason than before to suspect that the breed has a problem with elbow dysplasia and therefore would benefit from a breeding program regarding this.

Teachers and special education teachers play a vital role in the creation of a study environment that fosters productivity in students. The current study aims to further expand the knowledge regarding teacher?s perception of common work with developing an optimal study environment within the classroom and the educational institution. In order to achieve this, qualitative interviews have been performed and study results analyzed according Nilholm´s model of the three different perspectives on special education: The critical perspective, the compensatory perspective and the dilemma perspective.The study results show that the concept of order and study environment is not clearly defined among the interviewees. However, the concept appears to presuppose the teacher?s responsibility to create the sense of security and effective study environment to those students who express the wish to educate themselves (Children make the things right only if they have been shown the correct way to do it).

The purpose of the study was to investigate whether or not Icelandic horses are less severely affected in clinical symptoms of cough or decreased performance than other breeds of horses. A breed variation in chronic respiratory disease severity was suspected based on clinical experience at the Institution for surgery & medicine, large animal, SLU Uppsala. A retrospective journal study of 17 Icelandic horses and 17 Swedish Standardbred horses with chronic problems with cough and/or decreased performance compared several measurements of disease severity. The clinical signs, physical examination and laboratory testing results compared were respiratory rate, abdominal breathing, lung auscultation, endoscopy results, broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All parameters were available for all 34 individuals except for the blood gases, which were analysed, in only four Icelandic horses and four Swedish Standardbred horses. The only parameters that appeared different between the two groups were respiratory rate and pO2. The four Icelandic horses, which had blood gases analysed, had more severe hypoxemia.

The overall purpose of this master essay is to investigate whether there is an interest among people near retirement to contribute with their knowledge and experience after they reach the defined retirement age. Furthermore, I would like to investigate if they want to continue with their old jobs, full time/part time or to do something else, which is beneficial to the society. I also want to find out how the older people view themselves to continuing to work. Also which types of social and structural barriers that might exist for them and why. The aim is also to investigate what types of knowledge and experience they believe could be used in the future community.

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.
