Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals. A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact. Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial. The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.

Stunning of pigs at slaughter constitutes of primarily two methods; carbon dioxide and electricity. Both methods have advantages and disadvantages from an animal welfare point of view. The purpose of this study is to compare different methods of stunning pigs from a welfare point of view. Questions included in the study are 1) What differences are there, from an animal welfare point of view, between CO2 and electricity as methods for stunning pigs? 2) What alternatives are there to the methods currently in use? 3) Which method for stunning pigs is preferable from an animal welfare point of view?This report is a literature review.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

AbstractTo take the role of another is an important and a central part of human interaction. When we take the role of another we not only learn about them but also we learn about ourselves and how we interact with other people.  Social work in this form, working with directly with families in crises, is much about understanding other people?s perspective and feelings. It is important to know the strategy of one?s work and which perspective to work from.

The main purpose of this essay is to investigate the legal position for employers concerning protection against what employees can express about one?s employer in social media.It may regard dissatisfaction concerning employment, tort or so-called whistleblowing. The spread through social media may be comprehensive and thus cause more damage to the employer.Employees within the public sector as well as in the private are protected by the liberty of speech, which is constitutional, even the protection of sources or the right to criticize can offer some protection. This gives the employees the possibility to widely express themselves in private social media as long as it can?t be classified as a violation, which per se is very rare.However, certain differences between the both sectors will be pointed out.There are still no constitutional rights regarding social media, but a grey area has emerged concerning the legal position.

A growing problem in Swedish herbicide free agriculture, the Canadian thistle has been the object of several new trials, seeking methods for non-chemical weed control. The new trials have mainly confirmed earlier experiences; that the most successful methods of control are springtime ploughing, repeated cutting and competition from a stout crop. Row hoeing has also been proven effective. As opposed to earlier recommendations, half season fallow has shown to be a risky and often ineffective method of control. Trials regarding biological methods have shown that above others thistle rust (Puccinia punctiformis) may have the potential of controlling Canadian thistle the future. .

The annual cost of home care services of transport in Falun/Borlänge, is now at 31 million kronor. It is clear from previous research that it is possible to reduce these costs through a restructuring of the existing home-help service. The restructuring aims to have a higher proportion of older people, who are in need of care, to live in special accommodation, in order to reduce transport costs. Therefore there is a need for systems that allow home-help service to plan their operations in such a way that transport is working as efficiently as possible. Through better planning, there are profits to be done.

This study is preformed at Westbaltic Components placed in Töcksfors Sweden. Themain target in this study is to make one of the company?s assembly lines better andmore effective.

Nursing care of persons having dementia diseases affecting the frontal lobes, sets special demands on the staff, but the knowledge about how to best tailor nursing care is sparse. The aim of the study was to illuminate possibilities and difficulties in nursing care of persons having dementia diseases with frontal lobe dysfunction and was carried out as a descriptive, qualitative study, based on a review of medical records and interviews with nursing staff (n=10) that was analysed with qualitative content analysis. The difficulties were related to the patients lack of inhibition and judgement, anxiety, agitation, reduced ability to care for physical needs, egocentrism, imbalance between rest and activity, and depressed mood. The possibilities were seen in relation to the nursing staffs professional encounter, characterised by being distinct and consequent, being a step ahead, being flexible and catch the moment, being calm and create a positive atmosphere, being close and trusting and being and doing together. To receive continuous feedback and support was a prerequisite for the staffs? engagement.

The Swedish educational system has taken a step toward change in hopes of a better education by presenting a new national curriculum: Curriculum for the compulsory school, preschool class and the leisure-time centre 2011 (Lgr 11). I have therefore chosen to analyze the textbooks Champion 4 and Portfolio based on the objectives and areas of knowledge for grades 4-6 found in the syllabus for English in Lgr 11 in order to find out whether or not the textbooks are in harmony with the syllabus and if the textbooks can be used to help students meet the requirements found in the syllabus for the English subject.The purpose of this study is to analyze selected textbooks for the English subject for students in fourth grade to find out which of the curriculum?s requirements are met for grades 4-6, that is, goals and areas of knowledge and if they can be used in the compulsory school.The results of this study show that the analyzed books can be used in an education that today follows a new curriculum. However the education should not only be based on the textbooks. The teacher must take responsibility for designing an education that suits the intended student group, but also provides students with different learning styles an opportunity to develop in their individual ways.

Statistics indicate an increase in online shopping. This indication could result in the loss of safety factors for the customer, for example the possibility to physically examine the product, interact with professional store personnel and try the product before purchase ? factors which all could support the customer in her choice of company and product. The purpose of this study is to increase the theoretical knowledge regarding strategies in the area of trust-development between customers and companies. We have chosen to investigate what strategies web based companies apply and how they are perceived by their customers.

In order to make take-off and landing procedures possible at an airport, an organized allo- cation of slots is necessary. How these slots shall be distributed among airlines is, at pre- sent, governed by the European Parliament and Council Regulation (EEC) No 95/93 of 18 Janu- ary 1993 on common rules for the allocation of slots at Community airports. It is important for the air- lines to be allocated a beneficial slot. Hence it is of great interest for the airlines to ex- change and transfer the allocated times among themselves, a form of secondary market. Whether such practices are allowed or not is not regulated by specific detail in the regula- tion, which leads to legal uncertainty.
