The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

The purpose of this study is to identify a successful way of expanding a business on a global market, focusing on innovation products. An analysis was also made to see how internationalization theories are useful in businesses with innovation products. Four companies have been interviewed where two of them have innovation products (Proline AB and Q-Med AB) and the others are widely successful in exporting to a global market (Safegate Group and Weda Poolcleaners AB). Furthermore four interviews have been made with support organizations that have great experience in helping companies in this area (Svenska Uppfinnareföreningen, Almi Företagspartner AB, Exportrådet and The Swedish-American Chambers of Commerce).One of the results that can be identified is the diverse view and will to expand the business. The inventor often has a born global strategy in mind whereas the helping organizations rather expand step by step and only to one country at a time.

The background to this study is built upon the results that emerged from our former study: Elever med svenska som andraspråk i mångkulturella skolor - Bakgrundsfaktorer Tester och Utredningar (Odén och Bagge, 2006). Those results made us aware of the lack of cooperation in the work around immigrant pupils with special needs. In this study we have therefore chosen to look at the cooperation processes. The aim that we agreed upon was to explore the intercultural cooperation process around a few immigrant pupils in school year F-5, before and in connection with the pupils possible registration in the special school. We also wanted to pay special attention to the roll that the special need teachers played.

SammanfattningDenna rapport behandlar temat resurseffektivisering med avsikt att finna effektiviseringar kring tillverkningsprocessen vid gjutning av motorblock. Aspekter vi valt att fokusera på är gjutmetoder, materialval och flöden. För att kunna undersöka detta har teori hämtats från redan existerande litteratur samtidigt som en fallstudie gjorts mot Scanias gjuteri. Vid studierna av tillverkningsmetoder har sandgjutning, precisionsgjutning, gravitationsgjutning och pressgjutning undersökts. Gravitationsgjutning är den metod som används av Scania och därför används denna som referensmetod när jämförelser ska göras.

The purpose of this study was to examine if there are gender differences in computer use among the young. Our aim was to find out in what respects boys and girls differ, if at all. The main method of investigation is a literature review. We have also made a complementary empirical study in a public library. The literature studied principally covers computer use at home and in school.

The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.

Stjärnägg is a sales organization operating on the Swedish eggmarket, owned by nine Swedish packing companies. Those nine packing companies are not just owners of the sales organization, but at the same time competitors since they compete in the market when they do not sell the eggs through Stjärnägg.The purpose of this thesis is to evaluate the sales organization from a supplier and owner perspective. To answer the purpose of this study, qualitative interviews have been conducted with the owners of the egg packers. This has been done in order to get as fair picture of the sales organization as possible. From the answers of the interviews, a compilation has been made to be able to give Stjärnägg concrete proposals of improvements in the organization.

Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

The purpose of this paper is to examine the constructions of sexuality, which are produced when judgments concerning asylum are made, based on an asylum seeker?s sexual orientation. The question formulations are the following: Which constructions of sexuality are produced when necessary condition, fear of persecution due to sexual orientation, is applied in judgments regarding refugee status? Furthermore, how constructions of sexuality differ in the judgments where the asylum seeker has been consented and rejected is investigated. The empirical material consists of 13 judgments, which were announced between the years 2009-2013 by the Migration court.

Denna rapport beskriver konstruktionsarbetet av en testrigg som ska användas för provning av brunnslock. Arbetet är utfört åt Brunnspecialisten Sverige AB som säljer egenutvecklade brunnslock tillverkade av glasfiberarmerad plast. Dessa brunnslock ska godkännas enligt europeiska standarder och måste då bland annat genomgå belastningsprov.Anledningen till arbetet och att testriggen behövs är att de tidigare standarderna har blivit reviderade och därmed har provningarna blivit mer avancerade och ett automatiserat system kommer att krävas då det i vissa av fallen handlar om högcykelutmattning.Arbetet har utgått från den standard som reglerar provning av brunnslock. Detta ledde till en konceptstudie där olika förslag på utformningen togs fram och utvärderades. Beräkningar gjordes för att dimensionera komponenterna till testriggen för att säkerställa hållfastheten hos denna.

The purpose of this study was to examine the obstacles and problems prescribers of exercise on prescription (EoP) in primary care in Bollnäs and Söderhamn experience when using the method. It also aimed at examining if the barriers identified in previous studies also will be found in Bollnäs and Söderhamns municipalities. A qualitative study was made and four interviews with the managers of health centers in Bollnäs and Söderhamns municipalities were completed. The only inclusion criteria was that it would be a licensed health care professional at the clinic who work with, and prescribe the EoP. A content analysis was performed, which categorized the statements made according to their content.

Previous research has shown that children with multiple disabilities have been able to learn to make choices. Practising choice making is a good way to introduce an intervention using Alternative and Augmentative Communication (AAC). Choice making with objects should then be trainded before choice making with pictures. The present study is a single subject experimental design and was accomplished at a center for children with disabilities in Tanzania during 12 weeks. The primary purpose was to examine if the number of choices made by two boys with cerebral palsy increased after communicationintervention with objects and pictures.

Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.

Hållbar utveckling och globalisering börjar bli alltmer betydelsefullt för företagen med tanke på den dramatiska ökningen av konsumtionen. Förbrukningen av fossilt bränsle är en betydande faktor som har lett till konsumtionsutvecklingen och resurs överutnyttjande. Sveriges siktar på att ha fossilfria transporter till år 2030, vilket sätter en stor press på företagen när det gäller produktion, tillverkning, forskning och utveckling. Syftet med denna studie är att undersöka sambandet mellan ekonomisk tillväxt och hållbar utveckling, samt hur ett företag som Scania kan växa ekonomiskt och fortsätta arbeta hållbart. Studien baseras på kvalitativ metod som innebär närhet till källan forskaren hämtar information ifrån, för att få djupare förståelse av komplexiteten i problemet som undersöks.

Purpose: To investigate if Altman´s Z´-score model, which calculates financial distress, can be applied on companies established in Sweden and if the financial crisis in 2008 made previously healthy companies go bankrupt.Methodology: Quantitative studies with a positivistic foundation. Empirical data will be collected in order to examine if there is generalizability among the studied objects. Conclusions will be made by comparing the empirical data with the theoretical foundation. Financial distress in firms will be measured.Theoretical perspectives: Altman´s Z´-score model, designed to predict financial distress in private firms.Empirical foundation: A selection of 93 private firms that have gone bankrupt in the years 2008, 2009 or 2010. The firms selected all have a turnover that exceeds 20 million SEK.
