Sveriges djurskyddslagstiftning är en av världens hårdaste, men för att kunna upprätthållaen lagstiftning behöver man också veta var problemen finns och det är vi inte alltid lika brapå. Ett område där man vet att det föreligger djurskyddsproblem är hos övergivna katter,utöver det vet man väldigt lite om svenska katters levnadsvillkor. Ett område som man vetsärskilt lite om är ladugårdskatter dvs. katter som lever i och omkring ladugårdar, som intehar tillgång till att gå in i ett bostadshus och i de flesta fall har till främsta uppgift att fångaråttor. Enligt tidigare utlänska studier förekommer flera hälsoproblem hos ladugårdskatter,såsom virus, endoparasiter, ektoparasiter och trauma.

The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed. The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.

The retail sector is in a continuous development. What demand looks like and where the consumers want to shop has changed during the last years. Market place, demand, supply, external factors and politics affect how the retail sector develops. To make a market place attractive a variety of factors have to be considered.In Hong Kong a model called Rail & Property is used, this means that the development of the subway is integrated with the development of the city. The model is both successful and economically sustainable.Today the supply of shops and services in Stockholm´s subway stations is rather small.

Relationship between social behaviour, feeding behaviour and performance of boars using single-space feeders A study on the behavioural patterns of growing boars is presented. The study was preformed at Quality Genetics? boar testing station MÃ¥nseryd in Sweden. The boars were purebred Yorkshire, Hampshire or Landrace, born in nine different nucleus farms. The study is based on two batches of boars, with 63 and 69 boars respectively.

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

Today there are over 100 000 stray cats in Sweden and of these 10 000 are found in Gothenburg. There are several instances that try to reduce the number of stray cats. The problem for stray cats is primarily the suffering they may face in hunger, cold, predators, diseases, parasites, accidents, etc. The cats receive no veterinary care and may die from a simple infection that easily can be cured with antibiotics. Stray cats also can spread diseases to domestic cats, be a sanitary problem and compete with other small predators on prey. Authorities working with stray cats are the Country Administrative Board and the police authority.

Dagligen kastreras många honkatter under dissociativ anestesi i Sverige. Dissociativ anestesi anses vara en relativ säker narkos, med minimal påverkan på djuret. Detta gör att det finns en risk att dessa narkoser övervakas i mindre grad än de narkoser där djuren är sövda med gas. Syftet med detta examensarbete var att utvärdera hur dissociativa narkoser av honkatter i samband med ovariehysterektomi övervakas i Sverige samt genom litteraturstudier och en egen studie i mindre skala utvärdera vilken grad av övervakning som är önskvärd vid en dissociativ narkos samt om övervakningen i Sverige idag motsvarar detta. En enkätundersökning skickades under sommaren 2014 ut till 106 djurkliniker i Sverige varav 67 stycken svarade.

The large number of surrendered and feral cats is a big animal welfare problem all over the world. Populations of feral cats arise through a large number of unwanted cats which can lead to surrender of these, through cats allowed to roam free outside which can lead to the owner losing these and through the reproduction that occurs amongst these surrendered or lost cats. One aim of this study is to give an account of this problem. It is however difficult to draw general conclusions about these populations of cats since studies all over the world has been carried out on different types of populations, during different conditions and different periods of time. The welfare of many of these cats is presumably low because they are exposed to risks as disease, starvation, climate, traffic, other animals and humans.

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.

I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

I uppsatsen behandlar jag frågan: Vilka verktyg främjar en enkel väg till berättande med tekniken animation?Jag ifrågasätter idén om att man bör veta vad man ska berätta och hur historien ska vara konstruerad, innan man börjar berätta. I stället vill jag visa att förmågan till berättande finns inom oss alla, och jag vill i detta arbete prova en metod för att låta berättandet byggas upp i interaktion mellan ting, rum och människor. Mitt didaktiska syfte är att utarbeta ett pedagogiskt tänkande kring hur jag kan handleda elever till ett aktivt och kreativt skapande av berättelser genom animation.Detta har jag undersökt på två sätt. I den första undersökningen skriver jag om och analyserar mitt arbete som handledare i animation med särskoleelever på Utbildningsradions medieverkstad (UR) Pedagogiskt forum.

Salmonellos hos småfåglar har blivit ett ökande problem de senaste åren och studier har visat att det är den infektionssjukdom som orsakar flest dödsfall bland småfåglar. Salmonellos hos katter är ovanligt men utbrott har satts i samband med infektion hos småfåglar. Denna litteraturstudie tar upp vilka serotyper av Salmonella spp. som finns hos småfåglar respektive katter, hur bakterien sprids mellan småfåglar, och från småfåglar till katter samt vad som kännetecknar bakterien. Den serotyp som sprids mellan småfåglar och orsakar infektion är Salmonella Typhimurium och de fagtyper som dominerar är DT40 och DT56. S.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.
