Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

 This study examines the way Swedish students in Upper Secondary School respond to two excerpts from a classic Swedish novel. The paper?s aim is both to give an overview over some of the theoretical concepts concerning the field of reader-response criticism, and to describe and analyse what the students experience in their first meeting with an older text. The background to my interest is the many studies showing that young readers regard reading of fiction in school as boring. By using the method of written reading responses I want to contribute to a deeper understanding of how an older text can be received, understood and engage its readers.

Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations. The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses. The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.

Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.

The purpose of this thesis is to describe how principals apprehend the school library. In order to respond to this I formulated three questions: How was the improvement of the school libraries carried out in one municipality? Is the school library experienced as a part of the schools organization? How is the use of the school´s library experienced? To be able to answer these questions, for the purpose of this thesis, I have studied relevant literature on school libraries, the school organization and literature on qualitative methods. I have made six qualitative interviews. The objects of the interviews were three librarians and three principals.

In this thesis ? concerning didactics of literature ? I perform a reading and theoretical analysis of two pivotal works within reader-response theory, more precisely: Literature as Exploration (1938) and The Reader, the Text, the Poem ? The Transactional Theory of the Literary Work (1978), both written by Louise M. Rosenblatt. The object of this analysis is to examine whether Rosenblatts? theory and methodology can be used to accomplish understanding for ?the other?, what Martha C.

Denna uppsats bygger på fyra grundstenar; Svensk kod för bolagsstyrning, Combined Code on Corporate Governance, riktlinjer från OECD, EU:s rekommendationer. För att skapa förståelse för dessa olika regelverk samt möjliggöra en analys, har teorin om Agent och Principal, samt den om Corporate Governance använts. Förutom studier av regelverk har diverse intervjuer genomförts med svenska och engelska börsnoterade företag som lyder under bolagskoderna, samt även intervjuer med revisionsföretag. Dessa har fungerat som informationskällor, referensramar, och underlag för analys och slutsatser. Det ges även sammanfattningar av Svensk kod för bolagsstyrning, samt för Combined Code on Corporate Governance, en redogörelse för riktlinjerna publicerade av OECD och EU:s rekommendationer.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

The aim of this Master?s thesis is to examine the librarians? perception of the users of children?s and young people?s literature. Questions posed in this study are: How are the librarians described according to appearance, personality and interaction with the users? How are the librarians described compared to former studies on the subject? Which perception can be seen, based on Douglas Rabers?s theory which describes the role the public libraries can take in the society? The study is based on content analysis. We have examined 15 descriptions of librarians in both picture books and literature for young adults, published between 1985 and 2006.

Feline infectious peritonitis (FIP) is a feline viral disease with high mortality. There is no cure or any effective vaccine available today. Many questions are yet to be answered about this disease and the immune response in affected cats. The aim of the study is to evaluate two different techniques for the study of cytokine profiles in cats vaccinated with a vaccine concept against FIPV. More information about the immune response in these cats could give valuable information to better understand the pathogenesis of the disease and the development of an effective vaccine.

Den Europeiska Unionen är menad att fungera som en representativ demokrati, men de råder meningsskiljaktigheter om huruvida EU är demokratiskt. EU:s nya fördrag, Lissabonfördraget, är en institutionell reform av samarbetet. Representativ demokrati kan ses som en rad länkar i en kedja av kollektivt beslutsfattande, där varje länk präglas av relationen mellan huvudmän (principaler) och uppdragstagare (agenter). I varje länk delegeras makt från principalen till agenten, vilket innebär ett ansvar för agenten inför den man representerar. Syftet med denna uppsats var att analysera hur en eventuell ratificering av Lissabonfördraget förändrar de över- och mellanstatliga maktrelationerna i EU:s sammanlänkade statsskick, utifrån principal-agentteori.

View description: The purpose of this study is to investigate in what way the mother tongue language education integrates in a compulsory school activities and also which significance it has to the students who studies mother tongue language. My questions are following:How does the cooperation look like between mother tongue languages teacher, teacher and principal?How do students perceive the mother tongue language education?How does the mother tongue language education take place at the school?Method: This investigation is classified as a qualitative study and consists of theoretical points and empirical material such as interviews and observations.  Based on hermeneutic view of tradition which means that I interpret all my material.Results: My results of this study is that the mother tongue language education does not integrate with the other school activities and the mother tongue language teachers does not cooperate with other teachers or principal at this school. The reason for this is mainly because the mother tongue language teachers work situation. I´ve also seen that language has to do with the creation of a personal identity.

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.

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
