This report is a Master?s Thesis performed by Andreas Adolfsson and David Jacobsson atChalmers University of Technology. The purpose of this master?s thesis is to evaluate anew method for load-shedding, the voltage controlled underfrequency load-sheddingdeveloped by ABB. This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.

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.

The study concentrates on which significance the pre-school?s yard and the outdoor environment has and how it influence the young children regarding their development and learning. The study is carried out through observations of the children complimented by interviews of them. The results show that children?s outdoor environment is important for their development of mobility, language, social competence and learning about nature.

This survey tries to find out if and how we can be influenced of extreme low and strong frequencies in the area 0-40 Hz. A group of 52 teachers/musicstudents and non musicstudents was trying to assess what they thought, experiences and tried to describe why they thought as they did, when they listen on three different versions of same musical piece. Without low frequent bass, original and strengthened bass, randomly mixed. Several different musical pieces was used in same survey. The work also makes a commitment to theories about the people's hearing and the will of ?selfmotion?.

Breast cancer is the most common form of cancer affecting women. The treatment of breast cancer may lead to forcing the woman to remove her breast. The breast is a symbol of femininity and sexuality for many women. The purpose of this literature-based study is to describe women's experiences of altered body image and sexuality after mastectomy. This may provide a better understanding of the nurse in responding to these breast cancer patients.

The purpose of this study is to show what melancholy and irony in my poems express and what techniques that are used to accomplish these effects. Many theorists, among them Sigmund Freud and Julia Kristeva, characterize melancholy as an experience of loss, and therefore one of my questions is what kind of losses appear in my poetry. In search for an answer I analyze the texts from both a psychoanalytic and a sociological point of view. In the latter perspective I discuss the postmodern society using concepts from contemporary thinkers like Zygmunt Bauman, Fredric Jameson and Jean Baudrillard. Finally, I also examine if melancholy has an influence on the form of the poems.

Databases are an easy way of storing information kept together and accessible and can save time by finding the information easier. Cochleaimplant could be seen as a form of advanced hearing aid, this product consists of two parts, an external part that recieves sound and sends signals to the internal part through electromagnetism. The internal part is the implant itself and is surgically placed in to the cochlea. Örebro University hospital has just started working within the field of Cochleaimplants and are therefore in need of a database to store patient related information.The database problem was solved using Microsoft Access 2003 combined with the built-in support for Visual Basic, which is a sort of programming language. The result of the thesis work was a fully functioning database according to the given specification and is now being used at Örebro University hospital..

The company is currently in a stage of improvement and has therefore taken the help of students at School of Engineering, Jonkoping University. The current production is batch, production layout is fixed. A bottleneck is created after the first station which leads to large efficiency loss.  The meaning of this report was to provide a layout suggestion with balanced workstations to a new production line. The conditions were that the production line would be one-way, driven by customers order and meet a demand of 40 products per week.

The purpose of this study is to examine how the identity of teenagers is affected by the loss of a parent as well as what coping strategies support identity development. The reactions the teenagers exhibit, in such circumstances, will also be examined. To accomplish this,  a theory package was created, comprising theories in developmental psychology, identity work, coping and theory of grief reactions of children and teenagers. This package provided a broad perspective, which facilitated the analysis. Furthermore, it made it easier to address the purpose and the issue of the analysis.

Grief research generally demonstrates that children and teenagers who have lost a parent in suiciderisk developing severe psychological and physical morbidity, as well as social disabilities, in adultlife as a result of traumatic aspects of the death and complicated grief reactions. The youngbereaved also run a highly increased risk of developing suicidal behaviour or to commit suicidethemselves. Despite these alarming reports, the research field is poorly explored and studies thattake an interest in the long-term consequences and the subjective experiences of the bereavedyoungsters are lacking. A qualitative study using narrative methods has been carried out toexamine the experiences of four young women, who during adolescence lost a father in suicide.The study specifically focuses on the grief process, the short- and long-term consequences, and theneed for social support in relation to family, extended network and society. The study reveals thatthe women?s traumatic loss has shattered their basic assumptions about the world as a safe andmeaningful place.

In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.

Many pedigree dogs are suffering from inherited diseases or personality disorders caused by selective breeding. The Swedish lapphund is a breed that has been suffering from some loss of genetic variation due to the heavy use of only a few males. Concerns have arisen and crossbreeding has been discussed as a way to manage gene loss. Four breeds has been taken into consideration for this purpose; schipperke, finish lapphund, Norwegian buhund and Norwegian elkhound, black. These breeds has been tested theoretical by a comparison of mentality and health.

The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground to avoid air contact. The other way is to use acid to reduce the pH in the slurry to a level between 5 and 6 where the equilibrium is so strongly pushed to NH4+ that hardly any NH3 can be lost.

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.
