Analys av tanniner : från granbarksextrakt
The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.
Det är lätt att man buntar ihop dem. En kvalitativ textanalys med genreperspektiv om representationer av personer med funktionshinder i svenska TV-program våren 2007
The purpose of this Master?s thesis is to examine what role the new city library in Halmstad has for its users. The questions posed in this study are: What do the users actually do at the library? What roles are the most significant according to the users? Have the politicians succeeded in their intention of realizing a modern library according to the users? The theoretical starting point is Andersson?s and Skot-Hansen?s theory of four different roles of public libraries. In order to extend the model we added a fifth function; the one of aesthetical experience.
Användning av smärtskala på marsvin ? experimentell studie i klinikmiljö
Assessing and measuring post-operative pain in all animals is a challenge, but doing it in small mammals, for example guinea pigs, presents an even larger difficulty. Validated pain scales developed for use in dogs in clinical practice are currently available, but no such scale has been widely accepted for use in guinea pigs in the veterinary setting. In this experimental study, six guinea pigs that had undergone surgery and anaesthesia were observed for behavioural changes that could be associated with pain. The six guinea pigs were also given pain scores with the use of Colorado State University Feline Acute Pain Scale (CSU-APSF), a scale which uses both behaviour when not handled, body tension and response to palpation to evaluate pain intensity. The six guinea pigs showed a number of different behaviours, for example rigid posture, fixed stare and ?wet dog response? (the body is vigourosly shaken), that could be associated with pain.
Ungdomars fysiska aktivitet och dess betydelse för prestationen i skolan
This study where designed to investigate if there are any positive relationship between the extent of physical activity during adolescent's leisure time and the academic performance, and also if there are any negative relationship between the academic performance and the time spent in front of the television or computers. Another part of the study tried to find out if physical activity has a direct and immediate influence on the performance in school. 91 pupils (51 girls and 40 boys) in the 8:th year of the Swedish primary school, from three different schools participated in the study. All 91 pupils first responded to a questionnaire concerning there activities in leisure time. They where then tested in a mathematical test and the results where compared with the extent of physical activity and TV/computer time they had stated in the questionnaire.
Påverkan på elektronik och sensorer i radiologisk miljö
The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..
Stick to your knitting : Outsourcing av ekonomihanteringen hos några små aktiebolag i Västerås
Level: Master thesis in business administration, 15 creditsDate of seminar: 2009-05-29Title: Stick to your knitting ? Outsourcing of the economic function in some small private limited companies in VästeråsAuthors: Johanna Eriksson 1982johanna.erik@gmail.comSandra Hansson 1982shn04005@gmail.comTutor: Leif CarlssonPurpose: From a company perspective describe why the chosen companies in Västerås decided to either outsource or to have their economic function internally, define how the outsourcing process looks like and examine how the companies that have chosen to outsource have experienced their outsourcing situation. Further, we wish to contribute with advice for companies that are considering the option of outsourcing their economic function.Method: An intensive study of existing literature and a pre-study were conducted in order to create a framework for the thesis. The pre-study was conducted with one business counselor and two suppliers of economic services and resulted in local practical examples that supplemented the found literature. The main research consisted of semi-structured personal interviews among twelve companies in different sizes in Västerås.
Att navigera med gester : Gestbaserad teknik för framtiden
Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.
Aspergers syndrom : Några verksamma pedagogers uppfattningar om skolsituationen för ungdomar med A.S. på gymnasiet
The aim of this study is to examine the opinion of teachers as to the situation of young people suffering from Aspergers syndrome in the Sixth Form(gymnasium. In order to find this out I have chosen to interview four teachers with work experience of Aspergers in three different gymnasium in middle Sweden. They were confronted with the following questions: What resources are available for these pupils in the gymnasium? How do they experience that the school situation functions and how would they as teachers like the school situation to function for these young people at school?The result shows that special teachers have an extremely important function to fulfil. Those interviewed felt that there are sufficient resources available, for example guidance and further education for techers as well as both support and means for helping the young people.However, every teacher does not understand this handicap.

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.
Bookcrossing ? vad är det? En kvalitativ användarstudie av bookcrossare
The purpose of this thesis was to explore the phenomenon called bookcrossing. To fulfill this I have asked the following research questions: Why do people participate in bookcrossing?What functions do books have for bookcrossers? The method used is qualitative, semi structured interviews. Four active bookcrossers have been interviewed. These interviews revealed that bookcrossing as an activity in a medium sized town is very small.

In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.
Upprepade ljusstimuli orsakar interferens i mörkeradapterade elektroretinogram hos hund : en utvärdering av några av European College of Veterinary Ophthalmology´s rekommendationer för elektroretinografi på hund
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.
Narcissism och syskonplacering hos gymnasieelever
AbstractThe aim of this present study was to investigate whether there is a relationship between birth order and the personality trait narcissism using 181 individuals from Finnveden High School in Värnamo (115 females, 60 males, mean age 17, sd=0,94), in the context of the proposal of Sulloway (1996) that personality is influenced by the specialized nich-es siblings adopt in the quest for access to parental resources. A questionnaire which in-cludes Narcissistic Personality Inventory test, Birth order test and also Rosenberg?s self-esteem test in order to investigate if it might has an impact on narcissistic personality trait, was used. Results showed that there was no significant relationship between birth order and narcissism, however, a significant relationship between narcissism and self-esteem was found. Furthermore, there was a significant relationship between narcissism and the individual?s relationship with the mother.
Från Skiss till Diss
Over the past decade, the fashion industry has experienced a relatively high rate of consumption with material and clothing becoming increasingly subject to waste and disposal. As a result of the increased awareness within the industry the interest in CSR (Corporate Social Responsibility) amongst retailers has increased substantially in an attempt to shy away from the critically amplified media attention. In addition the underlying demand from external stakeholders has forced companies to ensure they focus and act upon each stage of the product life cycle.This study provides a further in depth analysis of the fashion industry and conveys the key messages and steps that firms are taking in response to the external pressures and requirements based on four different merged process areas. This research paper examines the impact of CSR on two Swedish fashion retailers Åhléns and JC and shows how accountability relates to the external expectations and norms that prevail in society. The result shows that the firms do meet the demands within each sub category as a response to market demands.
