Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

Purpose: The purpose of this study has been to investigate whether Frennberg & Hanssons earlier study of anomalies still are correct, and if these are valid for certain sectors. Methodology: In an effort to find seasonal patterns on the Swedish exchange market, we have used the average daily returns. By using these patterns we have created investment strategies which have then been tested over a 10 year period. We also used t-tests to verify our results. Conclusions: We have been able to prove a change in the seasonal patterns that Frennberg & Hansson presented in their study.

Abstract The increased focus on social capital theory has made its way into labour economics. This has led to the creation of a vast literature about the use of networks and informal search methods in the labour-market, a literature that to some extent also deals with immigrants search behaviour and their relatively high unemployment rate. Characteristic for the literature in the area is the lack of analysis of actual networks. Which types of contacts do these networks contain; how are the networks used in the labour-market; and which type of network generates a high amount of social capital. These questions are important for the general understanding of how social capital functions, within the labour-market, but also for the understanding of how immigrants use their networks in order to find themselves jobs.

Background: Fall injuries are a costly problem for society, with costs ranging up to 14 billion a year. In addition to economic loss accidental falls also creates human value losses and reduced quality of life for its victims. In order to prevent the occurrence of injury related to accidental falls healthcare providers utilize various scientifically developed risk assessment tools, one of them being Downton Fall Risk Index. Method: Empirical, quantitative cross-sectional study. Objective: The purpose of the extended essay was to describe the categories in Downton Fall Risk Index that have a bearing on patients' risk of falling while in hospital and in municipal care, and to illustrate how nurses can use the fall risk assessment tool.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

Genetic defects are caused by mutations in major genes where the gene?s protein product has a large impact on the physiology of the animal. The synthesis of the protein can be altered by a change in the nucleotide sequence, which can lead to malformation and in many cases death.One of the main reasons of increase in many genetic defects is the use of few bulls in breeding programmes, causing a reduction of the genetic variation. Genetic defects cause suffering for the animal and influences the production by, for example, increased costs due to misscarriages, lost milk production and expenditure for medical treatment. Bovine Leukocyte Adhesion Deficiency (BLAD) and Complex Vertebral Malformation (CVM) are two genetic defects that were widespread before the causative mutation was discovered.

This C-essay is a qualitative study designed to create a basis for understanding how managers involved in school affairs perceive the impact of merit points on students? chances to continue on to higher education and how this will affect individuals' life chances.The study is based on three interviews with managers involved in school affairs. In this paper grades, merit points and socioeconomic class differences are discussed.The aim of this paper is to answer the following questions:? What impact does merit points in language studies and the way different languages are valued, in the system, have for the individual and for society?? Who are the winners in the new grading system and who are the losers; how are different socioeconomic groups affected?The material was interpreted with the help of a report written by Ingrid Nordqvist and Monica Langerth Zetterman called "Secondary School competition field-a regional perspective", a paper written by Helen Raven who did a study on grades, national tests and social reproduction and the Frenchman Pierre Bourdieu's theories.The results show that class differences will increase and that it will be difficult to rise in the social hierarchy in the future..

The development of defoaming additives is steadily progressing and there are therefore always new and improved additives on the market. Some modern additives provide the desired defoaming effects by themselves, in contrasts to previous additives that needed to be used in combination with other additives. The task of this bachelors thesis was to evaluate the possibility of using these improved defoaming additives, with the aim to find alternatives that give the system better defoaming attributes while, at the same time, using less of the primary products. The tests were carried out in the coating type Teknocryl Aqua Combi 2780. The coating is a waterborne air drying acrylat-latex/alkyd based coating that can be used for both single coat painting and primer.

SammanfattningFrån och med den 1 januari år 2005 ska samtliga börsnoterade företag redovisa efter IFRS. Detta innebär bland annat att goodwill inte längre är föremål för planenlig avskrivning utan skall istället årligen testas för nedskrivningsbehov. Innan företaget kan göra ett nedskrivningstest måste all goodwill först ha fördelats ut på de kassagenererande enheter som väntas bli gynnade av synergierna i förvärvet. Därefter värderas goodwill med hjälp av lämplig värderingsmodell. Det största problemet för företagen med den nya goodwillhanteringen är att urskilja de olika kassagenererande enheterna.Uppsatsens syfte är att få en förståelse för den komplexitet som uppstår för företagen vid arbetsprocessen med de kassagenererande enheterna och frågeställningarna den ämnar besvara är; Hur organiserar företagen arbetsprocessen med de kassagenererande enheterna, från det att en goodwillpost har uppstått tills det att den fördelats ut över berörda kassagenererande enheter samt testats för nedskrivning? och Vad är företagens åsikter om regeländringarna i goodwillhanteringen?För att kunna besvara uppsatsens frågeställningar har fem djupintervjuer genomförts med företag noterade på Stockholmsbörsens O-lista, Attract 40.

The aim of this paper is to elucidate and analyze history teacher's didactic choices in the conflict between unequal educational materials and the requirements of equality in the curriculum of Swedish secondary school. The empirical data consists of interviews with five secondary school history teachers, observations of their lessons as well as analysis of their tests. The starting point was to investigate teachers' didactic work in the role as a bridge between the non-equal historiography presented in textbooks in history and the curriculum?s demands for equality. Three different approaches have been observed in the teachers' didactic work when considering gender perspective into their teaching: that women become extensions in a male-dominated historiography; that another part of the story is presented when a gender perspective is considered; and that the gender perspective is included in history teaching and becomes an integral part of all the content of the subject.Several of the teachers acknowledged that gender equality is less prioritized than the courses core content and related assessment criteria.

The aim of this project was to change the way cutting techniques are being taught. I wished to try a method which I believed to enhance my students´ participation and understanding of their education. My purpose was to reduce the gap between theory and practice. After conducting a learning style test I found that most of them considered the best way for them to learn was by combining practice with dialogue and reflection of the tasks being done. That is why we tried to start working with the practical elements rather than traditionally starting with the theoretical aspects, while carefully intertwining terms and language of the trade into the education.

Background and problem: The importance of banks was clearly shown during the last financial crises, when the crises that started in the banking sector spread to the rest of the world. This is one of the reasons that this thesis is focused on banks in particular, one other reason is that a lot of previous studies has chosen to exclude banks because of the fact that their balance sheet differ from non-financial companies. This thesis is a beginning in filling in the gap that exists in the knowledge of banks capital structure. Purpose: The purpose of this thesis is to prove that it is possible to explain the capital structure in banks and that differences in the capital structure of the banks in Great Britain, Sweden and the United states of America exists. Method: The fact that our study is partly a replication of two earlier studies made a deductive approach most appropriate.

It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.
