The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Abstract We have chosen to figure out why a majority in a home-help service group in west of Sweden is, or has been sick-listed. The purpose with our work has been to investigate our area to be able to come up with different factors which can have contributed to the high numbers of this particular group. We have worked with qualitative method and conversation-interviews to be able to answer our purpose at the best way. We had separate interviews with the ten employees at their work and these interviews we chose to record with a computer. The result we got were that the group had existed for about four years and since then, they have had several different directors.

The purpose of this paper is to examine what problems cabbage growers have with the Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become a larger problem for cabbage growers in several countries in Europe as well as in Sweden. In Canada the problems are so severe that the midge is classified as a quarantine pest and therefore certain rules have to be followed. I have collected facts of the biology, host plants and reproduction of the Swede Midge, as well as the growers experiences and the occurrence of the midge in Canada, Europe and Sweden. The Swede Midge is hard to control because of its short life cycle and the larvae are protected between the heartleaves of the plant. When the larva feeds on the growth point the plant becomes distorted, in some cases several heads develop or none at all. When the midge infests spring rape its flower buds become undeveloped and rosette like.

This thesis examines the Swedish labour market with a focus on the immigrant part off the population. There are big differences between the immigrant and particular non-European immigrant part off the population and native Swedes. In the first part off this thesis I will show that immigrants in Sweden have a higher rate of unemployment, lower rate off employment, lower wage incomes, higher risk off unemployment and are overrepresented in low skilled, low status jobs. Even when controlling for different factors such as education level, knowledge in the Swedish language, age etc. a big gap remains.

With this master thesis I wanted to find out whether Erik Fichtelius, an SVT employee, interview project with prime minister Göran Persson is acceptable according to the public service ideology. In order to do that I used Swedish newspaper articles to analyse the so called Fichtelius affair. I also gathered material on SVT and the public service ideology. The master thesis is based on sociologist Manuel Castells theories on mass media and television as presented in the Information Age. Castells claims that in our time different areas, such as politics and television, are melting together.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

The industry struggles with problems concerning physical damage to wiresand communication in remote areas. Introducing a wireless network canprovide a solution to these issues. However, introducing wirelesscommunication comes with a whole new line of problems that will becovered in this report. By utilizing the wireless communication standardIEEE 802.11 a product can easily be integrated into an existing wiredEthernet network (IEEE 802.3).An introduction to the standard IEEE 802.11 and a summary of existingproducts utilizing the standard for embedded systems will be giventhroughout the report. This report also tries to explain key parameters forwireless communication in an industrial environment.This project also consists of a design and an implementation part, where thechosen IEEE 802.11 standard will be integrated into the existing wiredAnybus-S Ethernet module from the company HMS Industrial Networks.The integration part of the project has resulted in a working prototype calledAnybus-S Ethernet Wireless that utilizes the IEEE 802.11b/g standard fortransferring data.The project has been really fun to participate in and it has been successful inthe terms that a working prototype exists, and the authors have gained theknowledge in the subject as intended..

Det här arbete behandlar grunderna i penetrationstestning, vilket är en metod föratt kontrollera säkerheten i datorer och nätverk genom att försöka sätta in sig isamma tankesätt och metoder som en potentiell angripare kan ha.Den teoritiska delen går igenom processen för hur ett penetrationstest kan gå tilloch vad som är viktigt att veta och att tänka på under penetrationstestet.Det presenteras även några populära och användbara verktyg som kananvändas för penetrationstestning, nämligen Nmap, Backtack, Nessus ochMetasploit, samt en nogrann beskrivning av några av de mest vanligtvisförekommande allvarliga sårbarheterna.I genomförandedelen utförs ett penetrationstest i en labmiljö, och sätter då deninformation i den teoritiska delen i praktik. De verktygen som används gåsigenom mer detaljerat och olika metoder för att använda dessa verktyg ipenetrationstestningssyfte testas.Penetrationstestet gås igenom stegvis, och börjar med att hitta maskiner pånätverket och även hitta detaljerad information och möjligheter för angrepp. Deninformationen används sedan för att hitta sårbarheter i maskinerna, och slutligenutnyttjas dessa sårbarheter för att installera ett remote-access program och gekontrollen till den angripande datorn..

This thesis concerns an energy audit of a food industry. The company's business consists of boiling and peeling shrimps, and producing mayonnaise-based salads. This type of work involves energy-intensive processes, such as steam generation, compression of air and refrigeration of large spaces. These needs are supplied with electricity. Furthermore, the industry is a major consumer of district heating, particularly for heating the supply air in the ventilation system.

This essay discusses in a comparative way the Swedish and Norwegian legal system, mainly laws that contain adoption regulations. It also compares the administrative work that the government in both countries practices in relation to the individual person. In this essay, focus lies on the legal rights of the child in the adoption process and how well the government and its service meet the requirements from abroad.This essay has shown that the government has many rules and regulations that regulate their work and that all the sub processes are designed to ensure the child?s best in the adoption in both Sweden and Norway. Despite some differences in the investigation process, the work is very much alike.

According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

The last few decades largeincreases in institutional and foreign ownershipin Swedish listed companies have created a concernthat the traditionalSwedish ownership model are disappearing.With increasing globalizationand ever morecapital-intensive markets, so have great owners forced to admitcapital fuelled institutionaland foreign investors into their companies. By from an agency theoryperspective examine how different ownershiptypes and ownershipconstellations affects the cost ofequity, we want to see if there is reason for concern. Is the change in ownership structure affecting theSwedish listed firms?Our results show that the owneridentity or ownership constellations don?t affect the cost of equity that much.The only owner-identity that shows a significant correlation with the cost ofequity is the institutions and they relate to a lower cost of equity. Theresults show that companies with two controlling shareholders relates to lowercost of equity which can show that ownership structure affects the cost.
