Förekomst av MyBP-C mutationer hos katter med hypertrofisk kardiomyopati :

Hypertrophic cardiomyopathy (HCM) is the most commonly diagnosed cardiac disease in cats. The phenotype varies from mild focal thickening to severe concentric hypertrophy at the left ventricle. Two separate myosin binding protein C (MYBPC3) mutations have been identified in Maine coon cats (A31P and A74T) and one in Ragdoll cats. All three of them seem to cause familial HCM in an autosomal dominant pattern. The purpose of this study was to investigate the presence of these three mutations in population cats of different breeds with HCM in Sweden. The results may show if HCM is present in the absence of these mutations.

Spatial TDMA in Ad Hoc Networks with Antenna Arrays

In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.

Jaktprov hos brittiska stående fågelhundar

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

Hållbar utveckling i Kungsängen : ett gestaltningsarbete med fokus på folkhälsa, biologisk mångfald och ekologisk dagvattenhantering

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

Hur förselektion av hästar till bedömning och tävling kan hanteras i avelsvärderingen

The Swedish Warmblood riding horse is a popular horse for sport in Sweden, and the breeding goal is to produce competitive horses in both show jumping and dressage. The breed has its origin in native Swedish cavalry horses but has been highly influenced by foreign stallions throughout the years. Breeding values are estimated based on the results from young horse field test, which are held for 3- or 4-year old horses, and competition data. The young horse field tests are highly correlated with later performances in competition. The total proportion of horses with own observations to include in the genetic evaluation are slightly under 50 %, and in most cases their pedigrees are known.

Utvärdering av möjligheten att införa en plattform för djurägarinitierad dödsfallsrapportering av hundar samt därpå baserad forskning och avelsurval

There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.

EU:s frihandelavtalsförhandlingar med Mercosur : Implicita orsaker bakom avbrutna och återupptagna förhandlingar

This essay is about the European union freetrade treaty negations with Mercosur. I have in this essay used a qualitative content analysis, to study from the EU perspective the reasons to why, the EU and Mercosur suspended the free trade treaty negations 2004, and after several years resumed the negotiations again in 2010. The purpose of this study is to gain a deeper understanding from the EU perspective of why free trade negotiations were suspended and then resumed. In order to achieve a deeper understanding of this event, I have applied neorealism and neoliberalism on the explicit statements and the implied actions, as these theories may provide different explanatory power of implied causes of negotiations.I have come to the conclusion that the theoretical perspectives can indeed explain explicit statements and implicit actions for suspended and resumed negotiations with Mercosur. The implicit reasons for suspended negotiations are among others that the EU has an egoist thinking concerning a free trade treaty.

Vinster med återvinning, Stena Recycling

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

Tvåstegsavvänjning av köttraskalvar med hjälp av nosbricka :

When beef calves are weaned abruptly at 5 to 6 months of age this triggers a strong stress reaction, since the animals have not yet untied the bonds to their mothers or stopped suckling. This is displayed as extensive vocalization and restlessness. Attempts to diminish the negative effects of weaning on sucking calves have been showing varying results. The study presented here emanates from the observation that when calves are weaned without human interference they are only prevented from suckling, but are still allowed to have social contacts with their mothers. The hypothesis was that calves weaned in two steps would be calmer, gain more weight, and be healthier than animals that were abruptly weaned. To investigate this, 15 calves where weaned in two stages (Group 2), by fitting the calves with nose tags that prevented them from suckling during 5 days prior to the separation of the cows and calves.

Effects of koccidiae- and nematode infections in first-year grazing calves :

Twenty-four calves, which had not grazed previously, were divided into four groups. They were subsequently inoculated orally with either E. alabamensis oocysts, O.ostertagi/C. oncophora larvae, or both. One group remained uninfected and was used as a control.

Genetic study of cryptorchidism in Swedish Icelandic and Standardbred horses

Samodling är en odlingsmetod som kan användas för att förbättra dagens odlingssystem. Metoden innebär att två eller flera kulturer odlas tillsammans under en större del av växtsäsongen. Samodling kan användas på flera olika sätt för att förbättra odlingsförhållandena för antingen huvudgrödan eller hela odlingen. Den har en bevisad effekt på olika skadegörare och kan minska angreppen i odlingen. Samodling kan även användas för att minska ogrässpridningen, förbättra mikroklimatet, samt öka antalet maskar och naturliga fiender i odlingen.

Avelsarbete med mjölkproducerande getter ? fokus på Norge och Frankrike

The main part of the goats in the world is located in developing countries, whereas active breeding programs are mainly restricted to Northern America and Europe. Goat milk can be processed to several products and goat cheese is the main product. An organized breeding program is carried out in France and Norway but is not present in Sweden. Important selection traits for milk producing goats include milk, protein and fat yield along with protein and fat content. Functional traits have been more important the past years and they have large economic importance for the farmers.

Mode en gråzon? : En studie av modebranschens position mellan konst och kommers

The purpose of our essay is to develop an understanding and an insight for the fashion industry. We want to examine what the creative industries can learn from the unique position that fashion hold in a field between commercialization and art. We used a theoretical ground to enlarge our understanding for the distinctive place that fashion holds. To gain further insight in the fashion industry we complete the theory with empirical facts. The empirical facts were collected through a qualitative method with deep-going interviews.
