This student report is about neutering male and female cats and compares early ageneutering to neutering at the traditional age of 6 months.The main focus in this report is early age neutering, which means that neutering isperformed when the kittens are between 6 and 16 weeks of age. This technique has beenused by shelters in the United States for a long time, to prevent the adopted cats fromreproduce and contribute to the problem of overpopulation.Two different surgical methods are also addressed; the ventral midline incision and thelateral flank approach. Ovariohysterectomy and ovariectomy are also compared.I also address which drugs are preferable when kittens are neutered and some importantguidelines where you have to be extra careful when dealing with kittens.These guidelines are the preanesthetic evaluation, calculating drug dosages and preventinghypothermia, hypoglycaemia and stress.The report also has a summary of the concerns regarding early age neutering such asanaesthetic risks, growth disorders and growth plate fractures, urologic diseases andimmune system dysfunction, obesity, altered metabolism and behavioural changes.The sex hormones and how they change after neutering is also included.At the end of the report there is a compilation of a questionnaire that consists of eightquestions that I sent out to various animal hospitals and veterinary clinics in Sweden..

This paper shortly describes the coronavirus family, bovine corona viruses (BCV) properties and two diseases that BCV causes, winter dysentery and calf diarrhoea. The purpose of the study was to compare different diagnostic methods to detect BCV. Different methods are discussed, PCR, ELISA, immunofluorescense and virus isolation. Investigations were made in three different herds with winter dysentery; one dairy cattle farm with about 100 cows of different ages, one testing station for bulls with about 150 bulls and another small dairy cattle farm with 26 cows and 20 replacement heifers and calves. Faeces and nasal swabs were analysed with PCR and ELISA. The result shows that PCR seems to be a reliable method for detecting BCV but that the ELISA test can not be used as a reliable diagnostic method to analyse samples from animals with winter dysentery..

This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.

BAKGRUND Kattens trombocyter har egenskaper som gör att dagens automatiska och manuella hematologianalyser ofta ger falskt låg trombocyträkning (pseudotrombocytopeni). Trombocyträkningen (PLT) riskerar att bli missvisande låg på grund av att trombocyterna hos katter kan vara mycket större än trombocyterna hos övriga arter, samt för att katters trombocyter in vitro ofta är så lättaktiverade att aggregat bildas. En del av de största trombocyterna räknas inte av de automatiska hematologiinstrumenten (framför allt impedanstyper) och trombocytaggregat medför att trombocyterna blir ojämnt fördelade i blodprovet. Vid sant låga trombocytvärden kan livshotande blödningar uppstå och det är därför viktigt att kunna skilja katter med sann trombocytopeni från katter med falsk trombocytopeni. Trombocytaggregering har effektivt förhindrats med prostaglandin E1. Prostaglandin E1 är dock mycket instabilt i rumstemperatur, vilket medför att effekten lätt kan utebli vid felhantering. Nyligen presenterade en studie analogen iloprost.

Behaviour problems are often behaviours that cat owners don´t like, but are normal to the cat. The reason to why cat owners experience certain feline behaviours as problematic is probably due to the current practice in cat housing. The ways that cats are kept today causes somewhat of a compromise between cat and owner and inhibits the expressions of the cat's natural and normal behaviour. The cat owners may misunderstand their cats behaviour, for example the cat owners believe that their cats perform certain behaviours because of feelings of guilt, hate, revenge or maybe to protest against something or someone. An animal hospital may help solve behaviour problems, but also help the cat owners to undstand their cat´s behaviour in an other perspective. The aim of this study is to investigate the need of a cat ethologist in animal hospitals.

During the late 19: th century the park Tivoli in Halmstad, today called Norre Katts park, was known as one of the most beautiful amusementparks of southern Sweden. This is a description that hardly anyone would use to portray the park today. The aim of this study is therefore to investigate what the park once looked like and how it has changed until today?s neglected state. The history of the place and by who and for whom the park with; 4 ½ acers with meandering paths, caves, an avenue, leaf halls and bowers, was created. Who designed the park in the year of 1843 is an unrequited question.

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

Den här studien är en analys av hur den ryske författaren Lev Tolstoj, genom kanonisering och uppkomsten av vissa mönster av texter, bilder och representationer, reduceras till tecken, symbol och ikon, samt hur denna symbol och ikon behandlas i två filmadaptioner - Leo Tolstoj (Lev Tolstoj 1985) respektive The Last Station (2009). Den teoretiska utgångspunkten är i huvudsak Jurij Lotmans kultursemiotiska teori och i synnerhet hans definitioner av termerna tecken, symbol och ikon. Uppsatsen visar, utifrån denna semiotiska teori, hur adaptionerna väljer att representera en viss bild av Tolstoj som en reduktiv strategi för att kunna skapa ett narrativ som måste infoga och välja bland en komplex uppsättning av bilder och självbilder, representationer och självrepresentationer.Resultaten av analysen visar hur bilden av Lev Tolstoj i Lev Tolstoj fokuserar på bilden av författaren som å ena sidan starjets, som en vis äldre man, som människor uppsöker, och å andra sidan som författare. Hans verk ges följaktligen stort utrymme och det refereras ofta till hans verk, och då i synnerhet till den senare produktionen av filosofiskt och religiöst material. Vad gäller de ikoniska elementen är det bilden av den gamle mannen i de enkla bondekläderna från de sista åren av hans liv som dominerar.

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

Examensarbetet är ett planeringsprojekt i direkt anslutning till Stockholms innerstad. Planområdet är ett avvecklat stations och spårområde, där framför allt gods har hanterats under det senaste seklet. Den ursprungliga användningen av området har successivt avvecklats, och ersatts av andra verksamheter i de gamla magasinsbyggnaderna i området. Spårområdena har omvandlats till parkerings- och uppställningsplatser. Sedan SJ lämnade området har planer tagits fram för en förnyelse av området.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

A new shipyard on the island of Beckholmen consisting of a new ship hall and complementary workshops. The program is extended with rentable industrial space for other smaller companies to take advantage of synergies with the yard and to create an active maritime cluster around Beckholmen. By building a marina and a port at the northern shoreline of the island the shipyard can expand their potential customers to non-commercial and larger recreational boats that are becoming increasingly common in Skärgården. The port is also supplemented with a combined naval fuel station, harbor office and a small café. The boat traffic in the region gets a additional stop at the end of the port and act as an additional gateway to Djurgården. Several small retail spaces with direct access to the water is created along the promenade between the port and Djurgården. The shipyard gets a modern and efficient industry building, while the island is made available to the public again, and Beckholmen will hopefully take an equal place in the city's consciousness as it does visually in the inlet to Stockholm..

During one week (9-13 May, 2005) the use of veterinary diets for the hospitalised patients att the University clinic was registered. The animal owners were interviewed by telephone six months later about the feeding after coming home. Four out of ten animal owners answered yes to the question if the veterinarian had asked what food their animal normally consumed. Out of 35 animals, 15 (43%) were prescribed to a veterinary diet. Among cats it was 8 out of 14 (57%) and among dogs it was 7 out of 21 (33%). Four animals out of ten were recommended a veterinary diet when going home, but 20% did not follow the recommendation all the way through and stopped feeding their animal the veterinary diet. Reasons that were given was that the diet didn't last the entire period, that the animal didn't need the diet anymore according to the owner and one dog that became to lean when fed the diet. The diagnosis for these three dogs was vomiting, foreign body in the digestive system and bloody diarrhoea.

Syftet med uppsatsen var att ta reda på hur trollformler kan överleva flera århundraden. Jag har studerat en formel som botar vrickning eller brott på ben och bygger på ett muntligt berättande. För vidare resultat har jag tagit med historiska skeenden för att kunna se vad som har påverkat dess överlevnad. Jag har även tittat på ritualerna och magin kring boteformeln. Dessutom ifrågasatte jag om besvärjelsen var en magisk eller en religiös handling.
