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.

The aim of this Master?s thesis is to investigate and increase the understanding of Swedish Public Library Websites and to determinate which activity they mediate. To analyse the Public Library Websites Andersson and Skot-Hansen?s model of roles for the Public Library has been used. This model in¬cludes four roles for the library: the library as a cultural centre, a knowledge centre, as an information centre and as a social centre.

Sports Marketing is a growing part in the world of sports today. Our main purpose of this paper was to analyze which role marketing plays for an ice hockey organization in the Swedish elite today. For this study we did a case study research on the Swedish team Södertälje Sportklubb, where we interviewed seven people. In addition to the people in the organizations we chose to interview two sport journalists. This research was made from an organizations point of view and all of the interviews were of qualitative character.

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.

Under Swedish tax law; the general clause in the Tax Avoidance Act is a method to prevent tax evasion. The purpose of the general clause is to prevent any tax avoidance procedures that the legislator has not been able to foresee. For the general clause to be applicable, four prerequisites need to be met. This thesis analyses the fourth prerequisite based on the principle of legality. The prerequisite concludes that a determination of the tax base, based on the procedure in question, is in conflict with the purpose of the legislation.

This Master Thesis treats the non monetarian aspect about the Internet Portal from a consumer and company perspective. The purpose of this thesis i st o give or create a picture and a tool, a model for how the Internetportal could be evaluated an valued. By creating a so called Dynamic Scorecard the authors of this Thesis have created a model throug which the purpose of this thesis is served. Through this model the authors have come to the conclusion that the Internet Portal can be evaluated through both economic, social, service and technical factors as well as through what relationship the companies or consumers value concerning the Internet provider. The product of conclusions of this Thesis is that there are three main factors upon wich the Internet Portal is valued.

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Introduction The genetic skin disease epidermolytic ichtyosis is caused by mutations in either keratin gene 1 or 10 and leads to blisters and hyperkeratosis of the epidermis. At cellular level the disease is seen as aggregates in the keratin filaments. Since medicines are hard to investigate and produce mainly due to lack of reproducible model systems, there is no good treatment available for this disease today. In this article we describe how an in vitro model consisting of cells from a stable cell line transfected with expression plasmids to mimic patient cells, may be a possible alternative for screening compounds for therapies. The first step was to generate an expression plasmid required to complete the in vitro model.

In this paper, we examine the attitudes of 16- to 19-year olds towards stealth viral marketing in the form of videos posted on websites such as Youtube. Apart from their general attitudes towards the phenomenon, we were also concerned with their views on the ethics involved in this marketing method and how this affects their view on the companies behind the advertising. To accomplish this, we administered a survey to a sample chosen by convenience. Using the Persuasion Knowledge Model and prior research on the subject, we then analyzed the gathered data and reached the conclusion that the respondents in our sample were mainly positive towards stealth viral marketing in this particular form, that they generally did not consider it unethical and that even though most considered the companies to be responsible for such videos, teenagers were not likely to take negative actions against them if they found out that a video that they had seen was in fact a stealth viral video..

This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs. Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.

Background: It is today common for companies to provide some sort of incentive for CEO's and senior management positions to motivate, retain and benefit employees within a company. This is in order to drive the goals of the CEO and management in the direction that is desired by the owner. Currently, the Swedish centre-right government has forbidden the use of such variable pay within state-owned companies. There are two different attitudes to variable pay, one that is in favour and one that rejects it. However most people agree on the fact that a well-functioning incentive scheme can be of great strategic importance for a company.Approach: has variable pay to CEO's had any effect on the company's profitability.Aim: the aim of the study is to compare companies who use variable pay to CEO's with companies that do not in relation to their profitability in terms of profit margins, yearly performance, returns on total capital and returns on equity.Method: the study uses a quantitative approach.

The retail sector is in a continuous development. What demand looks like and where the consumers want to shop has changed during the last years. Market place, demand, supply, external factors and politics affect how the retail sector develops. To make a market place attractive a variety of factors have to be considered.In Hong Kong a model called Rail & Property is used, this means that the development of the subway is integrated with the development of the city. The model is both successful and economically sustainable.Today the supply of shops and services in Stockholm´s subway stations is rather small.

This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.
