The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

The aim of this masters thesis is to examine how the educational work of the Swedish public library was regarded in the Swedish library journal Biblioteksbladet at three different periods of the twentieth century, i.e. the thirties, the sixties and the nineties. Using a theoretical framework from the field of professionalization and a methodological framework of hermeneutics, it is shown that the educational work of the thirties can be described as having a focus on free learning whereas the educational work of the sixties can be described as having a focus on public utility. The educational work of the nineties focuses on the information seeking process of the user. It is noted that this development during the century can be understood as a shift of the cognitive authority of the public librarians.

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

Background: When a child is diagnosed with food allergy with risk of anaphylaxis, it affects the whole family. The child must learn to live with a chronicle disease and learn the importance of avoiding the specific allergens that may cause a life-threatening condition. The parents must adapt to a way of life with limitations in the everyday life as well as a constant concern for the child. They must learn to handle an auto-injector and to recognize symptoms of a coming anaphylaxis. Aim: The aim of this study was to describe parent?s experiences of living with children who has foodallergy with special focus on anaphylaxis.

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

The aim of this literature study was to give a clear picture of what gastric dilatation-volvulus is, and how the acute- and postoperative treatment and care is managed. The general aim is to support and help the veterinary technicians in their clinical work. Gastric dilatation volvulus is always an emergency. The primarily goal when these dogs are hospitalized is to establish an adequate cardiovascular function. This is done by immediate intravenous fluid therapy followed by decompression of the dilated stomach.

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

The purpose of our study is to examine whether stress among social workers is present, and ifso, what strategies they and their supervisors use to manage work-related stress. The study isbased on a qualitative method. The data consist of interviews, with six social workers andthree supervisors. The study?s theoretical framework is based on KASAM, SOC-sense ofcoherence by Antonovsky, demand- control- support model by Karasek & Theorell, stresstheory by Hans Selye and coping strategies by Lazarus.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

This paper analyzes Allt, Martina Lowden's novel from 2006, from a media discursive perspective. The theoretical framework consists of Michel Foucault's discourse analysis, Friedrich Kittler's research on hermeneutic reading, and N. Katherine Hayles's studies of pattern?randomness controlled meaning production. Various examples on how communication technology influences the narrator?s act of writing illustrate the medial discourse surrounding the body of Allt.

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

This report describes necessary steps for an implementation of an environmental managementsystem at a secondary school and what would hopefully lead to an environmentalcertification, using ISO14001 ? or as a possibility ? one of the so called environmentalawards. To the largest part, the descriptions and activities are general and can be used at anysecondary school at all, but the current status analysis ? with the started environmentalinvestigation ? and the environmental policy are directly coupled to Wilhelm HaglundsGymnasium. The document should work as a process support for implementation of anenvironmental management system at a secondary school..

It?s not a new occurrence that girls have higher grades than boys. Statistics show the same at the Kallinge school in Ronneby. There is a great difference between boys and girls in their grades from the ninth class. There are many different factors that affect the pupils.

The main point in this diploma work lies to a beginning on analysis of the existingmodel of WoodEye scanner. The analysis aims to forming a view and understanding ofhow the scanner is designed and how it functions, and certain conditions around thescanner. On the basis of the result from the analysis and obvious criteria, has a numberconcept proposals been put forward. The concept proposals has then been evaluated andbeen compared with current concept, obvious criteria and compared to each other. Thebest proposal has then been developed far to a completed concept..

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..
