Site fidelity of a migratory species towards its annual range
Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.
Behandling av konfliktbestånd - problem och möjligheter :
Overdue cleanings have for a long time been an important topic of discussion within the forestry sector. When stands that have not been pre-commercially thinned are reaching the level of commercial thinning, many problems occur in terms of decision-making and economical outcomes. These types of stands are commonly known as conflict-stands.
The work was carried out partly as an interview survey towards representatives from the forest sector and the energy sector, partly as a case study of conflict-stands situated in Böksholm, north of Växjö and in Tönnersjö east of Halmstad. The criteria for the studied stands were that they had to be dominated by Norway spruce and be in a severe status of ?conflict?.
The aim of the interview was to get an overview of the situation today, and also analyse trends in terms of conflict stands.
Expansionsmaskiner istället för strypventiler - en effektivisering
In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.
Peas as feed for dairy cows
AbstractAn approaching overproduction of cereals and a future uncertain supply of non genetic modified vegetable protein feedstuffs have increased the interest in an expansion of the domestic production of protein feedstuffs in Norway. Besides rapeseed (Brassica campestris), peas (Pisum sativum) may be the most suitable crop for this purpose. Peas are characterized by having a relatively high content of crude protein, ranging between 20-26%, a high content of starch, 42-51%, and a low content of fat. In general, the energy value for peas is higher than for barley but lower than for rapeseed and soybean meal.Pea protein consists of albumins and globulins to 85-100%, which leads to the fact that a large part of the pea protein is soluble and degradable in the rumen. Starch in peas is on the other hand to a large extent resistant to rumen degradation compared to starch from other starch rich feedstuffs.
Hanteringsmetoder av reptiler på djursjukhus med hänsyn till stress och skaderisker
It is popular to keep reptiles as pets in Swedish households. The number of households reporting reptile ownership is more than 15 000 (SCB, 2006). This means that a veterinary practice should consider how to take care of reptiles as patients.
The aim of this study was to examine literature and studies concerning safe handling and restraint of reptiles as well as the effects of acute and long term stress response and to suggest a simplified plan for handling reptiles in a veterinary practice.
The result of literary studies is that common recommendations for safe handling and restraint of reptiles is based on old techniques and experiences from safe handling of wild animals. The main concern is safety for the veterinary nurse and for the reptile.
Stress studies indicate that acute stress response is not harmful for the animal i long term. On the other hand studies of the effect of prolonged stress are not conclusive.
Kokvigeproduktion baserad på köttraser : en fältstudie
Most of the beef production in Sweden has been integrated with milk production. Since the 1990:s, the number of dairy cows has decreased. A specialised beef production has developed in purpose to compensate for this decrease. The consumption of beef have increased in the last decade, but the Swedish production has no followed this trend. In 2004, the percentage of beef self-sufficiency in Sweden was 60 %.

Design and performance of Small scale sensory consumer tests
Small scale internal consumer tests provide a company with a cheap way to get valuable information regarding their products advantages and flaws. Therefore the demand for possibilities to do this kind of test has increased. This report is part of a new sensory project at Unilever. It presents a method for sensory comparison of the company?s own products with the corresponding competitor products.
Feromoninnehållande substansers effekt på hjärtfrekvensen hos kvigor i östrus och diöstrus :
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.
Bottenfaunan i Stensjöån och dess tillflöde Bokån : - en undersökning av tre lokaler
The purpose of this study has been to examine whether the bottom fauna of the stream Stensjöån, has been negatively influenced since the harvesting of peat began on the nearby peat moss Skäftesmyr or not. Comparison has been made with the results of index calculations from earlier examinations in the stream, two calculated indexes has been made, Danish fauna index and ASPT-index. The sampling was made with the kick sampling method, SS-EN 27 828. Three locations were chosen for the examination, one upstream from the peat moss, one just downstream from where the brook from the peat moss joins Stensjöån and a third location near the outlet of the stream to the lake Stensjön. The samples were sorted and the found animals identified to the taxonomic level required for the calculation of the two indexes.
Parasite detection in extensively hold Gotland ponies
Horses are herbivores that spend almost all day grazing. While grazing they are infected by different endoparasites through ingestion of infective eggs or larvae on pasture. The most significant equine endoparasites in Sweden are the equine roundworm Parascaris equorum, small (Cyathostominae) and large strongyles (Strongylus spp), the tapeworm Anoplocephala perfoliata and the pinworm Oxyuris equi. For many years have horses been dewormed on regularly basis, which has resulted in the development of resistance to many anthelmintic classes. Because of the problems with resistance it is since 2007 necessary to have a prescription on anthelmintics and faecal sampling is also recommended.
Vattenbehov och olika system för vattentilldelning till nyavvanda grisar :
We all know that water is very important for both animals and humans. When we are
weaning the piglets from the sow we must guarantee that the piglets can start to drink
more water instead of sow milk. The first thing to check is always the quality of the
water that is to be used. To secure that, you must take a water sample. If the water is
inadequate it can bring a lot of problems and diseases.
Undersöka förbättringspotential med verktyg från Lean produktion
In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.
Banktjänstemän och representanter från Skatteverkets upplevda nytta med att företag revideras av revisorer
Despite the fact that mandatory financial auditing has been abolished for small private public companies in Sweden we still see this service being used by these firms. Earlier research, papers and published articles tend to focus on the abolishment of the mandatory audits seen from the accountant?s point of view. There has however been less emphasis on the fact that 85 percept of the companies relived from the mandatory audits still utilises this service. We think that we have found a new and until now unexplored angel on this subject, and the purpose of our study has been to explore what the Swedish bank officials and what the Swedish Tax Agency?s officials think that they have to gain from a mandatory financial audit.The scientific method used in the study is deduction due to the fact that existing theories has been used to form the hypothesis.
Personas, en gökunge i användarcentrerad design : En undersökning av personas roll i samband med användarcentrerad design
The aim of this paper has been to examine personas role in the development phase and whether or not some of the criticism that have aroused against personas is valid or not. In this paper we examine the benefits as well as the downsides of working with personas both from a scientific point of view but also from the experiences of a small company located in the north of Sweden. Since personas much like many other powerful tools have pit falls aswell as do's and don'ts this paper looks to clarify what role personas should take aswell as how to minimize risk and maximize the usefulness of personas..
