Two species of bees in the genus Apis, real honey bees, has long been of interest for man. These two are the European honey bee, Apis mellifera, and the Asian honey bee, Apis cerana. In Vietnam, beekeeping is of great importance, both with A.cerana and A.mellifera. The aim of this project was to investigate if the introduction of the European honey bee in Asia has affected the Asian honey bee, and whether different pathogens from A.mellifera have been transferred to A.cerana. Totally 40 samples, 20 from every species, were analysed for 8 different viruses.

This thesis deals with query formulation in full text retrieval. The variables studied were query expansion and query structur[INS: e :INS , and the aim of the thesis is to study their co-effects on retrieval performance in a probabilistic system. The expansion was made with synonyms, and the structure by expressing facets and phrases. The study was performed using QPA, Query Performance Analyzer, which includes InQuery retrieval system and a sub-collection of TREC documents with its topics. The measurement used was precision at 11 DCV points.

The purpose of this essay was to examine whether there were any differences in social workers way of investigating boys and girls, age 13-15. The main questions we wanted to answer were; which were the factors that the social workers focused on? Did the investigations lead to a measure and if so, which one? How were risk and protection factors described and ana-lysed?To answer our questions we read and analyzed 22 reports, written by social workers 2004 at the department for teenagers and families at a social welfare service in Sweden. We came to the conclusion that there were some differences, but these were few and not extensive. Recreational activities was mentioned in a higher degree in the boys reports while health, housing conditions and network were mentioned more often in the girl´s reports.

This Master Thesis has its basis in a political decision made by Centerpartiet. The primary goal of the decision was to construct a new government agency, with the power to decide over all areas concerning social insurance. To be able to do this safely, by a merge of two different agencies, the thesis looks at different earlier merges for signs. First of all two agencies, Swedish Tax-agency and Swedish Prison and Probation Service, are studied because they are considered succeful in their earlier merges. Two main signs are that it took a long while and that the organisations worked with similar things before the merge.

Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.

The aim of this Master?s thesis is to investigate the factors of children?s voluntarily reading in their spare time. We also want to know if the children choose non-fiction books for their voluntarily reading. The method as well as the empirical basis of this study is qualitative, with interviews of twenty-eight children in ages between 9 and 12 years. We conducted nine interviews with 3?4 children in each group.

This study, a narrative analysis of it, deals with the term, home, its importance and the use of it by Child welfare investigators in the city of Malmö between the years 1930-1936. Commonly used and acknowledged, home stood for security and order while the term, street, had just the opposite meaning. Living in the countryside symbolized health and sensibility, while city life was considered to be cramped, dirty and immoral. The responsibility of achieving the liberals and conservatives ideal of a sunny, clean and orderly home was given to the woman of the house, as was the task of keeping the home morally correct, and providing the necessary atmosphere for proper upbringing of the children. Consequently, the basis of theory, using Karl Marx and Friedrich Engels in regards to the conflicts between the upper and lower classes, and even theories of Jane Lewis of woman´s connection to home and family, have been the grounds for the study.

In April 2007 we contacted Lennart Augustsson at Designpartners AB in Västerås. He came up with the idea to investigate and evaluate their construction of a interaction beam, CSB-beam. CSB is short for Connector Interaction beam. The beam is based on a horizontal C-profile of high-tensile steel and in the bottom of the profile are vertical flat bar welded so called block connectors. These block anchorsare also made of hightensilesteel.

The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks.

This thesis has been carried out to the Technology Group at industrial plant Tube Mill2012, which belongs to the Sandvik AB. Technology Group is a unit that takes care ofall requirements and suggestions regarding investigations, test runs and designmodifications. The main objective is to identify and analyze the existing initializationprocess to see where improvement opportunities exist and to come up withsuggestions for improvement, supported by previous research and literature. Anextensive literature search and case study has been conducted to provide a solidfoundation to refer to during the work. Completing the interviews and the workshopgave a clear picture of their unstructured work and approach, how the lowrequirements on the received orders caused problems for the group as well as thelack of a standardized resource allocation method provides major delay factors.Solution proposal then became a very easy process model in five steps with all theinformation gathered in one place.

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.
