The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

The aim of the study was to describe how patients experienced communication, treatment and costs at the dental hygienist program at Högskolan Kristianstad. The study was based on a questionnaire that was made at the patient clinic. The questionnaire was conducted by the treating dental hygienist student after the treatment. The questionnaire was answered in the waiting room. Collection of the material occurred during the month of March in 2009.

Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.

The music distribution in Sweden and the world is rapidly changing. The music industry, however, has been reluctant to change the way they distribute music. The consequence has been that illegal music files have been available for downloading to anyone with an Internet connection. Because of the illegal downloading a new law have been implemented in an attempt to stop this behaviour. Our theory is that in implementing the IPRED-law, the sites that were hosting most of the illegal material will experience a severe decrease in traffic.

The aim of this thesis is to discuss and analyse the American cotton subsidies? effect on the world market in general and developing countries in particular. The amount of U.S. subsidies is substantial compared to most other countries, but a great deal of the effect is due to the USA?s significant share of the market.

The purpose of this essay is to explore how social media affect the political orientation and commitment of youths. Three scientific questions highlight the purpose from different angles. The didactic perspective is discussed in the initial and closing discussion, and is analyzed in the corresponding chapter. Two methods are involved in the study; one survey and one interview with a focus group. The survey had a total of 98 respondents from four different classes, all in the first grade of upper secondary school.

Previous research indicates that the academic journal in many cases is the most valuable and important source of information in scientific work. The aim of this study is to investigate students usage of academic journals in comparison to their usage of other document types, as illustrated by the citations given in LIS students master theses 1999-2001. By comparing the students use of LIS journals with the use of LIS journals by international scholars we also wish to examine whether students and scholars use the same journals in their work. The international scholars are represented by references given in LIS journals 1999-2001, recorded by the citation index Journal Citation Reports. Questions: 1.

Purpose: The aim with the report is to investigate if the South East Asian customer on the food processing market base their investments on Total Cost of Ownership and if so, which are the cost drivers considered most vital. Moreover, do these cost-drivers diverge from the perception FP Ltd has, and if so, can a Total Cost of Ownership-model help to achieve a mutual understanding? Methodology: First a descriptive approach will be taken, identifying FP Ltd?s employers? perception on how to meet the customer. This will later be compared to our empirical findings of the actual customer behaviour in Thailand and Vietnam. Thorough analyse of the gap between the two parts will give us the outcome whether or not FP Ltd will have any use of presenting a quantitative model justifying their higher price.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.One reason for the reverse share split is that most companies have plans to imple-ment other company?s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent.

The aim of this thesis is to compare two different classification schemes with each other and see what the differences and similarities are when classifying literature concerning film and television. One of the schemes is of general kind, Klassifikationssystem för svenska bibliotek (SAB) and the other is a special system, FIAF Classification scheme for literature on film and television. The focus of the examination is on comparing the structure, contents and division of firstly the main classes and secondly on comparing the notation and the auxiliary tables in the schemes. The theoretical framework of the comparison is based upon theory of classification but the conclusions drawn are though mostly of a more subjective character. In addition to the comparison itself interviews have been made with four libraries, two with experiences of SAB and two with experiences of FIAF.

When the Tranemo library moved to new localities in 1991 there were also some changes made to make the library more user-friendly. The purpose of this essay is to see how a useroriented change can be done and how it has been perceived by members of the library staff and the library users.This is done by the following means:l) interviews with members of the library staff,2) a questionnaire to the users in Tranemo,3) a comparative questionnaire to users of the libraries in Skara and Lerum.The comparison was concentrated on how the library presents its material. The result of this comparison shows that even though there is a difference among the three libraries, the difference is small and it is impossible to say for sure that it has anything to do with the changes that have been done. The interviews and questionnaire in Tranemo give a positive picture of that library..

This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

This thesis tries to define factors that impact upon the feeling of exclusivity for users on travelorganizers websites. We have identified seven key factors that we believe impact this feeling andthose factors are newsletters, special offers/auxiliary services, registration/limited information,price, limited number of seats on a journey, deals for members and personal service. To researchthis we have conducted a questionnaire and performed interviews with people that are familiarwith travel organizers websites. To create an understanding for the results we have studied usercenteredweb design, affective design and the meaning of pictures. The results show that personalservice and price are important factors to make users feel that they get their requirements andwishes met.
