Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.

The purpose of this study is to examine the retrieval performance of three search engines, specialized in retrieving news articles: News Index, Excite News Search and Ananova. Thirty questions, grouped into three categories – politics, economy and sports, were used and the first twenty documents for each question were examined. The questions used were designed to be as current as possible and efforts were made to perform the searches with as little time span as possible between each search engine. The precision of the search engines was determined for each of the questions as well as for each category and for the combined categories. In measuring precision an average was calculated, intended to favour search engines that place its relevant documents early in the ranked list.

 This paper is made on behalf of Statistics and Research Åland, ÅSUB. The aim is to explain the turnover for companies in Åland, with appropriate variables. The main study variables are variables that consist of the Swedish and Finnish activity indices. The study variables also include variables which consist of tourists from Sweden and Finland and the introduction of the Euro in Finland. The data used is from the period January 1996 to June 2008.Different regression models for the turnover are tried and explanatory variables are selected by use of stepwise regression, backward elemination and forward selection. The final model includes activity indices for Sweden and Finland, the introduction of the Euro, tourists from Finland and an autoregressive component of order one .

När ett nytt databassystem ska tas fram och införas i en organisation ska funktioner och krav på systemet identifieras och analyseras i en designprocess. Ett krav på ett databassystem kan vara att systemet ska uppvisa en viss prestanda. Designprocessen leder så småningom fram till fysisk design av databasen och dess applikationer. Det kan finnas flera olika lösningar för fysisk design av databasen och dess applikationer som tillgodoser kraven och funktionerna som ska finnas i systemet. Dessa olika lösningsalternativ ger olika prestanda.

The aim of this thesis is to map the research area of scientific collaboration within Library and Information Science LIS. The purpose is to find out who is doing research in this area, who they cite and if they get cited by other scientists outside of LIS. Scientific collaboration is an interdisciplinary research area with researchers from different disciplines such as LIS, human-computer interaction, psychology and sociology. We have concentrated our study to North America, Ireland, Great Britain and Scandinavia. In order to find researchers, we visited the websites of all universities with library and information science faculties in the chosen countries.

The main purpose of this essay is to investigate if Latvia´s pattern of trade has become more similar to the mature market economies, after Latvia´s independence 1991.Today, the intra-industry trade (IIT) dominates the trade of mature market economies. One of the pioneers of intra-industrial trade is Paul Krugman, who was the first to emphasize the importance "of scale and consumers' desire for variety" in explaining the basis for modern commerce. Customers get more variety and usually cheaper goods when the market gets bigger. I mainly use the modern trade theories to explain the trade pattern in Latvia. To measure how Latvia has developed its intra-industry trade, and thereby is approaching the mature market economies´ trade pattern, I use the Grubel-Lloyd index (GL-index).

Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.

Syfte: Studiens syfte är att undersöka om AP7 uppfyller sitt mål att ge sina sparare minst lika bra pension som övriga premiepensionssparareMetod: Uppsatsen baseras på en kvantitativ metod. Avkastningar riskjusteras med hjälp av Treynorkvot, Sharpekvot och Jensens Alfa för att kunna jämföras mot varandra.Slutsatser:AP7:s riskjusterade avkastning ligger något under Sveriges övriga premiepensionsfonder sett till både PPM-index och genomsnittet för de nio mest valda PPM-fonderna år 2013. AP7 har presterat en sämre riskjusterad avkastning än SIXRX och en bättre riskjusterad avkastning än en svensk statsobligation sett till undersökningsperioden..

Background and problems: All that is stated in social media might not always sometimes be right, which has consequences for the individual's view of the described phenomena. The individual interprets and takes in mass media messages, which can lead to that the wrong information makes believed to be is correct one. The news media?s photo illustrations might pictures result in bad images of the suburbs. Hovsjö, residential area in the city of Södertälje, occurs in the media depicted as is a bad place to live due to the high rate of crime there.Purpose and Issues: My main research question is: How do young people view their residential area Hovsjö in comparison with the image they believe consider is given in that the news media gives the area? Further questions of the study are: How do the young people of the district describe their residential area? How do the youth's react to the news media images of Hovsjö? Has the neighborhood helped to form their identity?Method: In my data collection I have chosen a qualitative approach with observation and semistructured interviews.

Syftet med denna uppsats är att undersöka om det föreligger ett positivt samband mellan frihandel och ekonomisk tillväxt, dels i afrikanska länder, dels i länder tagna från hela världen. Vad jag genom min uppsats främst vill söka svar på är om en ökad grad av frihandel i Afrika bidrar till en högre ekonomisk tillväxt. Genom att även inkludera andra länder i min undersökning, försöker jag dessutom ta reda på om sambandet mellan frihandel och tillväxt ser annorlunda ut ur ett globalt perspektiv.Som metod använder jag mig i uppsatsen av en regressionsanalys. Som mått på frihandel använder jag mig av ett index utvecklat av den amerikanska organisationen Fraser Institute, kallat Freedom to Trade Index.Mina regressionsresultat visar på att Freedom to Trade Index ej har något statistiskt signifikant samband med den ekonomiska tillväxttakten i de afrikanska länder jag undersöker. I min ?världsundersökning? visar sig däremot indexet ha ett positivt samband med den ekonomiska tillväxttakten.

The park at Djäkneberget and its surroundings is a beloved area in the city of Västerås. The area is one of the most popular sites for outdoor life and recreation of all sorts and it attracts different kind of people at different times during the day. The park includes a pond-system where protected species of frog and toad live and breed. These animals have been the objects for many discussions concerning whether to explore the closeby areas or not. The prospected area is situated just next to one of the main ponds and consists of valuable foundationwalls were experts predict that the frogs and toads spend the winter. The municipality has now decided to restore this area to parkland. Because of the areas fascinating history I have chosen to do some research and give a short resume about it. For example are the existing park of Djäkneberget and its founder described together with a short description of the watersystem with the watertower that is situated in the area.

Hofstede constructed a culture dimension called Power Distance, measuring the inequality of Power. Germany and Sweden have relatively similar values according to his world-renowned research. But a series of interviews of Swedish entrepreneurs in Germany shows that these perceive a large difference in inequality of power in the two countries. This essay seeks to explain the difference between these subjective-qualitative experiences and the objective-quantitative data of Hofstedes Power Distance Index. We propose that a combination of differences in communication, exercise and visibility of power and formality influence the way Power Distance is perceived.

Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.

This quantitative study, with qualitative elements, intended to investigate the empathic ability among students and its change during social work education in Sweden. The study used a self-assessment form in the form of a questionnaire sent out to 8 of the 15 universities around the country. Respondents who participated in the survey studied in semester 1 & 2 and semester 6 & 7. The instrument which were used, measure the empathy level of the respondents and was a Swedish translation of the instrument, the Interpersonal Reactivity Index (IRI) which is a proven self-assessment form. IRI consists of 28 questions divided into 4 areas (subscales), which together provide a score, where a higher score corresponds to a greater capacity for empathy.
