Mastitis is the most common disease of dairy cows. Mastitis can be painful for the dairy cow and causes economical losses for the farmer. These losses are due to decreased milk production, more working hours for the farmer, treatment costs and possible costs due to culling of the cow. The udder inflammation, mastitis, is often caused by bacteria infection. One of the most common bacteria found to cause mastitis in Sweden is Staphylococcus aureus (S.

Swedish sawmills of today suffer from unsatisfying economy with high costs and low benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner. Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are mainly manual but can in some rare cases be automatic.

This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.

This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.

Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

The intention of this study was to examine the interaction between authorities. More specifically it had a purpose to look at the ongoing cooperation between social workers and staff of special homes of closed institutional youth care. The sanction system for young offenders? reform of 1999 where young people between the ages of 15-17 who have committed serious crimes, can be sentenced to secure institutional treatment instead of prison, aims to counteract the harm which can result from a stay in prison. The social welfare board in the young person´s local authority and the national board of institutional care shall cooperate during the youth?s placement at the special home of closed institutional youth care.

The formation of sovereign states in regional blocks has become an essential feature in the world system. Therefore, the purpose of this paper is to investigate which motives and driving forces that affect the creation of projects of regional integration outside Europe and the Western World. By choosing the Latin American project of integration ALBA (the Bolivarian Alliance of the Americas) as a case of regional integration outside Europe and the Western World, the study investigates the motives expressed by the most prominent actors of the project, Venezuela and Cuba. ALBA is chosen as a representative and a unique case and through the consumption of the gramscian and the realist approaches, the essay defines two motives that affect the creation of projects of regional integration. As a way of investigating the actors? motives, the paper studies political statements, especially those of the Venezuelan president Hugo Chávez, and official positions expressed in central documents and declarations.

Today?s housing system for laying hens has limitations for the hens natural behavior. Despite the current law of prevention of cruelty to animals, this might implicate health problems for the hens. This degree project is aiming to improve the situation for laying hens in cage-systems. The aim with our project is to bring forward a draft of a cage that improves the welfare of laying hens.

This master thesis has been a product realization process. Having BRIO:s walking cart as thestaring point the purpose was to further develop the principle of such products and at the sametime broaden their sector of use. The final result is to be regarded as a complete solutionmeant as a foundation for further development at the BRIO Company. The product aims tosatisfy the demands and needs of the target group called theon the go parent. Trends, qualityand purchase power are features that characterize this particular target group.The project resulted in a walking stool namedBRIO Circus after its source of inspiration.

Behavioral problems are one of the leading reasons for re-homing and euthanasia in dogs. It is estimated that between 40 ? 87 % of dogs suffer from some sort of behavioural problem, making it an important animal welfare issue. Separation anxiety is one of the most common behavior problems encountered in dogs after problems related to aggression. This thesis is aimed at examining the etiology behind separation anxiety related behavior in dogs based on existing literature as well as comparing and evaluating the efficiency on suggested treatment protocols.

Today a trend can be seen towards fewer dairy farms and increasing number of cows per farm. Larger farms set a higher demand of more labour efficient milking systems. The time to enter and exit milking rotary platforms is crucial to maintain a high cow throughput. This study is a project initiated by DeLaval in order to evaluate the cow throughput and cow behaviour during entry and exit in two types of parallel external rotaries with different bail designs. The two rotaries compared were DeLaval parallel rotary PR2100 and PR3100HD.

The subject for this paper is the Class Action against Skandia Association, a civil organization formed in 2003 with the aim of claiming compensation for some 1.2 million life insurance customers. The background to its formation was one of the largest financial scandals in Sweden in recent times, involving a number of questionable affairs within the insurance corporation Skandia and its subsidiaries, most notably the life insurance company Skandia Liv. The interests of both the stake- and stockholders of the company seem, in certain ways, to have been grossly misrepresented. The scandal, as well as the reaction it spawned, pose a number of questions. In this study, we focus on two: a possible, and in many ways apparent crisis in the representation of interests in Swedish society, and the role of civil society in upholding the balance between these interests.We argue that what is often held to be the ?greed? or ?immorality? of individuals in scandals such as Skandia is, to a great extent, a mere reflection of the ?rational? underpinnings of modern-day capitalism.We find that trust has been a key mechanism of control in the relationships between consumers and agents in pension and life insurance markets, and that ?the Swedish model? that distinguished post-WWII Swedish society was a model heavily based on trust towards existing models of bureaucratic governance.

The purpose of this study is to examine the view of Swedish language teachers on the role of fiction and of school libraries within the compulsory school?s teaching of Swedish of form 6-9. The questions to be answered are:? What part do Swedish language teachers (hereafter called teachers) think fiction is playing regarding the pupils inclination to read and reading promotion?? What is the attitude of teachers regarding the function of fiction in the Swedish subject?? What do teachers consider being the role of the school library in education, and can this be related to the local school library resources?To answer the questions a questionnaire was sent out to thirty-five teachers. Four qualitative interviews were also carried out among the fourteen teachers that answered the questionnaire.

The aim of this study is to examine possibilities and barriers for an introduction of electric vehicles in Sweden. The study has an interdisciplinary approach and thoroughly examines the essential topics which influence the future of the electric vehicle. The study reaches from answering the question on why electric vehicles lost the game to petrol cars in the early 20th century, to sketch how the difference in total cost of ownership will be between electric vehicles and petrol cars for the coming 20 years. Apart from these subjects the main topics of the study are today?s and tomorrow?s situation regarding technology, charging, fuel, market and economic incentives from an electric vehicle perspective.
