I denna rapport predikteras livslängden, med avseende på utmattning, för en hjullastarskopa. Två av de mest kritiska svetsarna utvärderas enligt IIW:s (International Institute of Welding) rekommendationer genom nominella spänningsmetoden, hot spot-metoden och effective notch-metoden. Beräkningarna utförs med hjälp av finita elementmetoden. Genom att utföra töjningsmätningar på hjullastarskopan i drift erhålls spänningsdiagram. Dessa uppmätta spänningsdiagram analyseras med rain-flow count-metoden.

Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.

The purpose of this study is to evaluate the relation between certain chosen fundamental factors (emission trading rights, hydrological balance, interaction with continental Europe, fuel prices) and the spot price at Nord Pool. Particular focus has been put on the trade with emission rights since it is only now their actual impact on electricity prices can be studied. The relationships are measured with regression analysis which includes both R2 and the simulation possibilities of ARX models. The studied period covers 2008 and 2009 with partly daily data and partly weekly data. Owing to the expected higher importance of the fundamentals during the winter months the winter 2008/2009 has been studied separately.

The aim of this study is to look closer at collection development and the use of collection development policies in Swedish public libraries, with the help of a few examples. Through interviews with three librarians in three different public libraries and an analysis of these libraries? collection development policies, the authors try to find out how the creation of collection development policies takes place in these libraries, how these librarians use the policy, how these policies have been followed up and revised, and also to see what the policies of these libraries include. The material of the study suggests that a lot of work is required to write the policies, and that the written policy itself is seldom used by the librarians. The interviewed librarians still find the policies useful because the writing of them gave a detailed understanding of what the collection of the library contains.

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.

Horses are made to eat mainly roughage and it is essential for optimal health to offer them an appropriate amount of roughage with good hygienic and nutritional qualities. To produce good hay at the right time and be able to keep the hygienic quality until next summer is a problem. This has the effect that horse owners today choose haylage and silage to a larger extent. Science in this area is scarce, i.e. if the change from hay to silage has any effect on the horse.

Eco Log AB i Söderhamn är en tillverkare av skogsmaskiner. De tillverkar både skotare och skördare. På deras skördare sitter fyra pendelarmar som ersätter hjulupphängningen på fordonet. Dessa motverkar att fordonet lutar vid körning i sluttningar. Varje pendelarm drivs av en hydraulkolv som justerar nivelleringen.Då inga beräkningar med avseende på utmattning och livslängd genomförts sedan en omkonstruktion av pendelarmarna är det nödvändigt att analysera och utvärdera pendelarmarna.

This M.Sc. thesis is a material application evaluation commissioned by the advanced body engineering department at SAAB Automobile AB. The purpose of the thesis is to evaluate implementation of the innovative sandwich design material Hybrix into an automobile body. Today the most commonly material used in the body is galvanized steel sheets and by shifting material to Hybrix several problematic issues have to be dealt with. Hybrix is an innovative sandwich sheet that inherits thin stainless steel face sheets and a stainless steel fibrous core.

AbstractThe aim of this essay is to analyse what roll repression has had in the making of my unpublished collection of poems entitled Hopp som i hare. I examine how the autobiographical subject abortion has influenced the writing process and the outcome of the poems. By presenting literature that?s been important in the making of the collection I show some thoughts and ideas about Post Abortion Stress Disorder, a diagnosis without scientific grounds. In a discussion I go through the whole writing process from subject and genre choice through the revisions till the final version that were sent to be commented by the class in creative writing at Växjö University 2008.

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Bull terrier hereditary nephritis is caused by a mutation that leads to an inadequate synthesis of collagen type IV, which is an important component in the basement membranes. The inheritance of the mutation is autosomal dominant in bull terriers and progression to renal failure takes variable time, from several months to ten years. Proteinuria is the first clinical sign of the disease and the diagnosis is confirmed by transmission electron microscopy of renal tissue where typical ultrastructural changes in the glomerular basement membrane (GBM), thickening and multilaminar splitting are found. This study was performed in order to find out the occurrence of hereditary nephritis in bull terriers in Sweden through examination of urine samples and renal tissue and comparisons with how the disease is described in the literature. Urine samples from 76 Swedish bull terriers were collected and examined for proteinuria.

The aim of this master's thesis is to describe the management of free Internet resources in three Swedish research libraries. With the starting point in the increased quantity and importance of these resources, together with reflections on the change of the concept of collection, the thesis shows how and to what extent these freely accessible Internet resources are being integrated in the day-to-day work with collection development. It also elucidates the problems with the free Internet resources from the research libraries points of view. The study is based upon analyses of collection management literature and qualitative interviews with librarians at the chosen libraries. The thesis shows that the research libraries still have not come very far in their work of integrating the free Internet resources in their collections.

Acute bacterial prostatitis is a common disease in older male dogs. It gives symptoms such as fever, pain, tiredness, infertility, unwillingness to mate and sometimes symptoms from the urinary tract. It is common that you do an ultrasound exam on dogs when you suspect prostatic changes. In this study 15 dogs diagnosed with acute prostatitis at the small animal clinic at SLU in Uppsala were examined. The clinical signs and the ultrasound pictures were put together in retrospect.

The Secret Fashion Council blends spirituality with fashion, art and design. This jewellery collection shows the connections between parapsychology and quantum physics, based on the study of matter and energy, that everything in the universe is built of vibrations. Many believe psychics have the ability to sense this. By using the skills of a psychic, the Secret Fashion Council invites the wearer to have the jewellery ?read? and evaluated in a most special way, tracing the wearer?s spiritual past, present and future.
