Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Rangordningens inverkan på beteendet hos nötkreatur (Bos taurus) och dess konsekvenser för djurtillsynen :

Extensively kept animals for meat production have the right to live in a good environment. Cattle (Bos Taurus) as social animals live in small herds in the wild. When holding animals extensively new problems have arisen regarding human ? animal interactions. One welfare problem is to be able to come close enough to the animals to investigate their health condition.

Cross-sectional study of the prevalence of Babesia bigemina in Uganda : wildlife-livestock interface at and around LMNP

Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).

Resultat av tjugofem års mätningar av Cs-137-halter i älg i Uppsala län

At the end of April 1986 reactor number 4 of the nuclear power plant at Chernobyl explod-ed and large amounts of radioactive particles were then released into the atmosphere due to both the explosion as well as the consecutive fire of the graphite core. A cloud of radioac-tivity was spread over the northern hemisphere, including Sweden, due to the prevailing wind directions. The radioactive particles were washed out from the cloud by rain and snowfall in some areas of Sweden and deposited on the ground. The deposited radionu-clides, primarily cesium and iodine isotopes, were later absorbed into the soil and taken up by the roots of the plants. Some of these radionuclides, like 137Cs, still persist in some of the terrestrial ecosystems at relatively high concentrations which lead to contamination of the meat of moose, roe deer and wild boar even today.The two municipalities Heby and Uppsala, in the eastern part of central Sweden, experi-enced a relatively large deposition of 137Cs which resulted in high levels of 137Cs in moose and other game.

Monogami hos fåglar

Man har förr trott att fågelpar inom många arter, t ex albatrosser och kungspingviner, är varandra trogna livet ut. Syftet med denna litteraturstudie är att ta reda på om det finns något vetenskapligt stöd för sexuell eller genetisk monogami hos någon fågelart. Uttrycket ?monogami? kan ha flera betydelser. Social monogami är att en individ lever i ett parförhållande med endast en partner åt gången. Sexuell monogami innebär att ett par kopulerar bara med varandra, och detta baseras på observationer.

Äppelpressmassa i Sydsverige - nuvarande användningsområden och möjligheter till nya produkter

Pomace is the solid remains (i.e. stems, pulp, seeds, and skins) after pressing for juice. The annual production of apple pomace is 593 000 ton worldwide. Its field of application depends on local conditions. In order to investigate the field of application of apple pomace in the Southern Sweden, six persons on companies with production of apple juice were interviewed.

En bra plats för lek : kreativ och tillgänglig lekplats i Hedemora

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

Reproductive physiology of the female cat

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.

Parkplan för Kungälv med förutsättningar för sociala värden :

To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect. On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place. The physical environment and the interpretation of it gives possibilities or obstructions for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds. The physical environment is also a part of the total interpretation of a town.

När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning

Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made. A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

Angry birds, Instagram eller Runkeeper? : En kvantitativ studie om vilka faktorer som påverkar individer vid val av mobilapplikationer

Försäljningen av smartphones och mobilapplikationer är något som de senaste åren har haft en stadig tillväxt och inget verkar minska expansionen, snarare tvärtom. Idag står smartphones för en tredjedel av all försäljning av mobiltelefoner och det laddas årligen ned miljarder av tillhörande mobilapplikationer till dessa mobiltelefoner. Att konsumenter väljer att ladda ned mobilapplikationer är tydligt, men vilka faktorer påverkar konsumentens val av mobilapplikationer?  Syftet med denna studie är att ur ett företagsperspektiv beskriva vilka faktorer som påverkar kvinnor och män i deras val vid nedladdning av mobilapplikationer till sin mobilenhet. Tidigare studier inom ämnet har inte vidrört eventuella samband/skillnader av påverkande faktorer mellan kvinnor och män vilket väckt ett intresse hos oss att undersöka detta.

Undersökning av förekomst av okända virus hos svenska fjällrävar med encefalit :

The artic fox is under threat of extermination in Europe. The population decreased strongly at the beginning of the twentieth century because of intensive hunting. The artic fox was placed under protection by law 1928 in Sweden but despite this the population has had difficultly to recover. This can depend on several reasons, but the main threats are shortage of food and competition from the red fox. Along with Norway and Finland, Sweden has carried out a project called SEFALO (Saving the Endangered Fennoscandian Alopex lagopus), whose objectives were to prevent continued decreased populationnumbers and through, for example supplementary feeding, help the population to recover.

Hemlösa katter i Göteborg med omnejd

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.

Akustisk trädgårdskonst : att ge sonisk karaktär åt en plats

Ljud och trädgård är kanske inte det första par man tänker sig som gifta men de tus historia kan spåras längre tillbaka i tiden än man kan föreställa sig. När jag bestämde mig för att skriva min kandidatuppsats om akustisk trädgårdskonst trodde jag att ljudinstallationer i trädgårdar och parker var ett nytt fenomen. En helt ny värld öppnade sig framför mina ögon då jag insåg att så inte var fallet. Konstgjorda ljudkällor, såsom gyllene fåglar och vattenorglar, har kommit och gått genom tiderna medan naturliga ljud, såsom vind och fågelsång, bestått. När det kommer till vår egen tid är trädgårdsljud, även om moderna material och tankesätt används, en konstform som starkt präglas och inspireras av sin historia. Du kan skapa olika sorters ljudmiljöer i din trädgård beroende på vad du väljer att använda för material.
