With the development of the Internet, illegal copying of electronic documents has become a growing problem. There is an increasing need of prevention in the field of pirate copying. One method is to mark the document by changing some of the words to synonyms. In this way it is possible to construct legal copies which do not differ in content but still are unique. Since the copies of the documents are unique, it is possible to trace the owner of a document and accordingly call him or her to account for pirate copying if several exactly similar copies are reaching the market.

The purpose of this thesis is to present and analyze population developments within Umeå municipality during the period 1992 to 2012. The study also aims to discuss growth trends presented in previous papers to seek common factors and get a deeper understanding.Data for 1992, 2002 and 2012 on a sub area level supplied by Umeå municipality was used. The study shows a continued positive development across almost all sub areas, but a differing growth rate from centre to periphery, and also a diversified medium age among the inhabitants.While the city center continues to have the highest growth of population during the studied years, a recent trend seems to point to a growing popularity to settle in the outskirts of the municipality, primarily near the coast..

The purpose of this examination paper has been to examine the situation for Swedish as a Second Language Programs in relationship to their interaction with the parents of the stu-dents. This case study was performed at two schools in the county of Stockholm. A com-parative analysis of both national and local documents for school governance was used to analyse the contents for incidents of parental involvement in schooling. Furthermore, qualitative semi-structured interviews were carried out with five staff-members holding key positions. The findings of the study are that schools tend to practice parental involve-ment only to the level that it is recommended in the national documents.

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

The purpose with our study is to increase our knowledge about how personnel in different activities experience the work with childrens who is growing up with addicted parents. What the personal experienced as important facts was structure and flexibility to take care of all children´s special need.Something else they experienced was, during discussions with children it´s important to listen to them and confirm their self-esteem.We have found that there are many well-functioning activities of this kind of children, but there are difficulties to have the parents to take the children to the activities.The personal believe that this is because the parents do not realise their addiction problem enough. The respondents expressed a which to get closer to the school so they can increase cooperation and reach more children in this way, and a lot of these respondents also point out that the community where ever the children are has a obligation to report or notify the social service if there are any children that need care..

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.

The final thesis ?Hardy palms for scandinavian climate? describes the family Arecaceae both from a general point of view, and with individual descriptions of seven different species that are known for their coldtolerance. The descriptions of each species is brief and the intention has been to give an introduction to some specific species known for their hardiness. Seperate chapters discuss topics as hardiness, pests and other problems and a short instruction for growing palms on open land in scandinavian climate. Finally a short discussion about continued research on this topic and some conclusions ends this final thesis.

The report aims to show how outdoor environments have been shaped with the purpose of experiencing them from the inside of buildings, through an overview perspective. Two Danish gardens are used as examples. One is the Baroque garden in the garden of Frederiksborg castle in Hillerød. The Baroque garden is thus a part of a larger garden. The second garden is the Charlotte Garden, a relatively newly constructed garden within a housing complex in Østerbro in Copenhagen. Both gardens are analyzed on the basis of visual expression and structure. In the report, it is also discussed how the contemporary society have evoked the different ways of shaping the gardens.

The interactive whiteboard (IWB) is to be found in many classrooms in Sweden, and its number is growing rapidly. There is a lack of research of the use of the IWB in Sweden. The Swedish National Agency for Education refers to English research where the investment in the IWB in school is huge. In this study I will investigate how the IWB can be used as a mediating tool in the learning process. My study examines how interaction pattern appears when the teacher teaches with the IWB as a tool.

The focus of the thesis is: how conditions for agriculture in the Republic of Macedonia today may form the basis for development of the agricultural sector towards conditions needed for future accession into the European Union. The method for investigating this question has been to look at newly available farm monitoring system (FMS) data from Macedonia. Also to look at the latest government policies created in the country for the agricultural sector and rural areas in relation to the requirements for EU accession. Articles and empirical studies published by other authors related to the questions which arise in this study have been reviewed and presented herein. Trade relations, trade patterns and national economic and agricultural trends are displayed to provide a background overview for the study of the agricultural sector.

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

This essay describes the philosophy of science that Thomas Kuhn puts forth in his work The Structure of Scientific Revolutions. The question is, does his description of the scientific paradigm work as well today as in the examples he gave in the book?The conclusion is that there are certain factors that make for a number of differences between science today and, for example in the seventeenth century. There is also a growing theory or vision of a post normal science laid developed by among others Jerome Ravetz. This theory or vision is an idea of a science close to peer-communities and fast as well as critical decisions involving opposite values..
