This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.

AbstractBackground: Inflammatory bowel disease involves major changes where psychological and physical stress becomes a part of ones daily life. The ability to adapt and cope well with the situation, increases the chances of feeling satisfied with life. There are various management strategies that people with IBD use to cope with their daily life.Aim: The aim of this study is to describe strategies that people with inflammatory bowel disease use to manage their daily lives. A further purpose is to describe the study group in the included articles.Method: A descriptive literature review. This study is based on 12 scientific articles, searched in the databases Cinahl and Pubmed.

The Swedish public inquiries and most of the political science advocate reforms in the spirit of participatory democracy to strengthen the democracy. Although it is striking how limited and narrow the scientific documentation is in analysing the effects of participatory democratic reforms. Still, many of the local governments in Sweden are reshaping their organisations according to the participatory democracy model. Is it a trend and a symbolic action or a veritable action of good-will of the politicians?The paper argues that the idea of participatory democracy has become popular and widely spread.

In 2010, SAS received the "On time performance service" award by Flightstats. This award was an affirmation of long-term work, both in projects and as an ongoing process, which the company sought to systematically improve punctuality on its flights. The extent to which SAS followed the values and the underlying theories of the cornerstone model for total quality management was the main issue in this essay. Whether there are conditions for the company to get even further by working in other ways was also investigated. In addition, the importance of punctuality in relation to customer satisfaction was discussed.

The main focus of this study is to explore Swedish soldiers? experiences of the transition back to everyday life after international service missions. This includes the help and support that they have received and also what barriers to care they have experienced during the transition back to everyday life. The theoretical perspectives of this study are social identity and stigma theory. This study was performed using a qualitative method and includes six individual interviews with active duty officers within the Swedish armed forces.

Introduction: The health for individuals with intellectual disabilities is asubject that is prioritized by the Swedish Institute for Public Health. Socialsupport has been proven to be important for health and quality of life. Despitethis fact there is no research available regarding the influence social support hason health and quality of life for people with intellectual disabilities in Sweden.Aim: To describe social support and the consequence of social support forhealth and quality of life for individuals with intellectual disabilities. Method:A litterature review of research in a defined area with a descriptive design.Systematic searches for articles were done in several databases and ultimately16 articles were chosen. Themes and categories were created with respect to theaim of this study during the analysis of the articles.

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.

Sense of coherence amongst employees with reduced work-capacity at Samhall.Sanela Jakupovic TrostekScientific essay in public health, 15 hp, Academy of Health and promoting Working Life, University of GävleThe aim of this study was to examine how employees at Samhall who has reduced work-capacity experienced their sense of coherence (SOC). The study includes gender, age and civil status in the analysis. The study includes 34 respondents which are divided as 20 men and 14 women. To measure SOC a quantitative method with a 29 standardized questionnaire was used.It was found that the employees felt, in general, low SOC, which means more difficult adaptation to their life situation. Noteworthy is that 70 % of the men in this study showed low SOC compared to 35,7 % of the women.One conclusion that can be drawn is that within Samhall, it showed that women had a higher SOC mean value than men which means they are more equipped to handle, understand and find meaning in their work life. Keywords: Antonovsky, Samhall, disability, work-capacity, sense of coherence (SOC).

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.
