To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.

Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

In this study the author attempts to identify factors that are determinants for why some pupils in Swedish grade school have high status in comparison with their peers. The study takes on the characteristics of both an ethnographic and a literature study by comparing the findings of interviews carried out with students of a first grade class with previous research. The study identify several tools for analyzing of how status may be understood in specific situations.The study also finds that important factors for gaining high status amongst children in aschool classes might be the ability to apply access strategies to get accepted in social interactions, such as game play, have the ability to create games that are enjoyed by peers and social skills, to name a few. Overall the study shows that children's game play with each otherare crucial for their social interactions and their social position. The study also show that children that have earlier established relationships with other children in a specific group alsohave a better opportunity to establish a high status position..

The background of this research is that Swedish food products have hard to compete at the home market, depending on imported food products that increase more and more for every year that pass by. The ethic values LRF associate with Swedish food products, many customers have hard to put in relation with condition of foreign agriculture. Most customers today inquire high quality, safety and convenience in the food which they are eating. The source of their food seems to have less meaning. Many restaurants and bigger households appreciate Swedish food products and wants to buy them but price differences against foreign wares are to high. We have done oral interviews with wholesale dealers, restaurants, public purchasers and with different market organisations, there we have discussed buying strategies, the way they see the primary producer, the conscious of guests, choice and attitudes to Swedish and foreign products, distribution of power in the food market chain and to what position and suspension, they want the ranks of suppliers to have. The result shows the share of imported wares within restaurants and bigger households are at a high level and will continuing increasing. Within these sectors the final consumer in many cases put less effort in the origin of the raw source of food.

Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.

This is a project showing a proposal on how a high-rise building gains qualities similar to middle rise houses of 7-9 stories. The closed, isolated and often anonymous life in the high building opens up through gardens. The resident meet the outdoor environment on the balcony, or has direct access to a garden.Instead of moving in a closed core, the resident will meet the climate and outdoor conditions as soon as he or she leaves the apartment.The project consists of two parts, where the first is presenting a building proposal, the second is expanding the knowledge through background research. The topics are history concerning the skyscraper and the skyscraper globally, closing up with the situation in China..

The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

This study investigates how tagging is being used in a new way when members of a Swedish dating site get to tag themselves in an act of self-presentation with the aim of meeting new people. In the study seven members of the dating site Mazily were interviewed about their self-presentation, tagging and identity formation there. The questions concerned how they formed their own tags, but also how they interpret and use other members' tags in their search for a potential partner.I have been using queer theories for this study, in order to find out what kind of norms and structures that lie behind and affect the members' behaviour on the website. My study finds that the interviewed members to a high degree reflect about both their own and other members tagging and self-presentations. Although they spend quite some time trying to analyse other people on the website they have a great sense of understanding that a person may give two very different impressions on the site and offline.

This paper researches how the palimpsest concept is used in relation to landscape, and how it can function as a tool within landscape architecture. Palimpsest originally refers to old parchment handwritings, where new text has been applied on top of effaced, but still discernable, earlier writing. Superimposition of information is the core of the palimpsest concept, used within a range of scientific as well as cultural fields. The purpose of this paper is to find how a landscape palimpsest can be distinguished among the many different layers of landscape, such as historical or cultural, and to examine the potential use of the concept in theory and practice of the landscape architecture field. The study is conducted as a literature survey, examining the use of the palimpsest concept within academic works related to landscape.

The unique ability of wheat to produce leavened bread is mainly due to the gluten proteins present. As consumers are more and more attracted to bread with high fibre content the use of wheat gluten will also increase in order to obtain bread with good volume and appetizing characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the original flour. This method is not widely used in the milling industry but could possibly be of interest if protein rich fractions with favorable protein quality can be produced.

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

The purpose of this thesis is to illustrate how non-profit organizations map the market of potential donors and how they apply their knowledge about the motives of the potential donors. The case-study of Church of Sweden Aid shows how a Swedish non-profit organization applies this in the daily work. In its strategic marketing the organization actively use marketing surveys in different forms. By employing an analyst Church of Sweden Aid has a possibility to make another step forward in order to understand its donor market and to adjust its strategic marketing plan to it. Church of Sweden Aid says that they don?t work with the donor?s motives.

The aim of this Master?s thesis is to examine how the gender system is described in fantasy novels. The theoretical framework is based on Yvonne Hirdman?s theory on gender system, primarily the two basic principles: the principle of dichotomy, of separation between the sexes, and the principle of hierarchy, of man as norm. The method used is idea analysis which is a form of textual analysis.
