Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

This essay is about the European union freetrade treaty negations with Mercosur. I have in this essay used a qualitative content analysis, to study from the EU perspective the reasons to why, the EU and Mercosur suspended the free trade treaty negations 2004, and after several years resumed the negotiations again in 2010. The purpose of this study is to gain a deeper understanding from the EU perspective of why free trade negotiations were suspended and then resumed. In order to achieve a deeper understanding of this event, I have applied neorealism and neoliberalism on the explicit statements and the implied actions, as these theories may provide different explanatory power of implied causes of negotiations.I have come to the conclusion that the theoretical perspectives can indeed explain explicit statements and implicit actions for suspended and resumed negotiations with Mercosur. The implicit reasons for suspended negotiations are among others that the EU has an egoist thinking concerning a free trade treaty.

The textile business is one of the oldest industries of our time, and it employs nearly 1.4 million workers within the European Union alone. It is not unusual that this is the foundation of a country?s industrialisation. Even though the industry brings many positive factors, there are also negative factors that will influence the industry?s growth in the future.

I dagens Sverige konsumeras årligen stora mängder kläder. Nyproduktion av textil har en betydande miljöpåverkan med bland annat stor åtgång av vatten samt mängder av kemikalier. Ett alternativ till allt nyproducerat skulle kunna vara andrahandsmarknaden för kläder.Syftet med studien är att undersöka om de kvinnliga kunderna hos butikerna Myrorna och Beyond Retro konsumerar färre nyproducerade plagg för att de konsumerar second hand- och vintagekläder.Vi har använt oss utav en kvantitativ undersökning där vi intervjuat totalt hundra stycken respondenter i anslutning till Myrorna och Beyond Retros butiker. Vidare har vi genomfört fem stycken kvalitativa intervjuer med vana konsumenter hos ovannämnda butiker, för att fånga deras resonemang bakom svaren.De kvantitativa intervjuerna visar på att en liten majoritet anser sig konsumera färre nyproducerade plagg för att de konsumerar second hand- och vintagekläder. Samt att det överhängande motivet bakom köpen var att second hand- och vintagekläder är unikt och trendigt.

Denna studie har genomförts för att undersöka hur Meat Free Mondays kampanj för att minska människors köttkonsumtion representerar och presenterar relevanta frågor om miljö och hälsa i delar av deras externa kommunikation.Syftet har varit att se hur miljö- och hälsofrågorna presenteras och representeras i Meat Free Mondays digitala kommunikation via videoklipp och delar av hemsidan. Vi har diskuterat vilka motiveringar som finns för att helt eller delvis sluta äta kött och utgått från tidigare forskning och teori i miljö- och hälsokommunikation. Vidare har vi utgått utifrån begrepp som kommunikationskampanjer och social marketing, och utifrån ett teoretiskt ramverk över miljö- och hälsoutfall undersökt vilka motiv och retoriska resurser som används i kommunikationen. Det har även diskuterats vilken roll och verkan Paul McCartney har som ambassadör för kampanjen.Studiens metodologiska ram har baserats på Karlberg & Mrals neoaristoteliska retorikanalys av både text och bild, och huvudsakligen de tre appellerna ethos, logos, och pathos. Materialet innefattar fyra videoklipp från Meat Free Mondays YouTube-kanal där Paul McCartney framför tal, samt delar av Meat Free Mondays hemsida, med innehåll som berör aspekterna hälsa och miljö.Studien visar att innehållet av Meat Free Mondays kommunikation kombinerar olika strategier för att stärka kampanjens teser. Budskapet förmedlas genom att anspela mycket på människors ekologiska drift och gemensamma värderingar, och användandet av den retoriska appellen pathos framträder tydligt i materialet.

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.

This thesis studies two instruments within EC-law, affecting asylum issues, the Schengen Convention and the Dublin Regulation. These instruments are developed as a result of the free movement of persons in the European Union, and the development of the free internal market. The member states are afraid of losing control of who is residing within their borders, as their border controls has been removed, and these instruments are made to protect the member states now that their own means of control are gone. The thesis explains the relationship between the free movement and asylum issues and shows the connection between them. Its focus is aimed at the free movement of workers and how the European court of justice has interpreted article 39 to increase the workers ability to move within the union.

According to Swedish tax legislation, investment funds are taxed differently depending on if the are Swedish or foreign. The difference between the investment funds lies within the taxation of received dividends and the opportunity to shift the liability of tax of received dividends on to the funds shareholders. This measure is only available to Swedish funds. The question in this thesis is whether this difference is discriminatory against foreign investors and therefore constitutes a forbidden restriction against the free movement of capital stated in article 63 EUF Treaty.The European Court of Justice (ECJ) has given several preliminary rulings on this type of legislation and its compatibility with the principle of free movement of capital. It is not compatible with the free movement according to the court.

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

The relationship between free trade and the environment is often considered conflicting and the debates surrounding it are infected. My thesis deal with this conflict and how environmental concerns are integrated in three regional free trade agreements, North American Free Trade Agreement, The common market of the southern cone (MERCOSUR) and Southern African Development Community (SADC). I point out how the organizations differ from each other in this respect and I present a possible explanation to why they differ. The explanation is founded on the theory of the environmental Kuznets curve and that environmental concerns will depend on which level of development the member states in the organizations have. To judge and rank the organizations I have composed a model based on a pre-existing description of the trade and environment conflict.

The aim of this paper is to map and analyze what role Swede's played in King Leopold II's colony in the former Congo Free State. Letters and messages that arrived at the Congo Consulate in Sweden between 1895 and 1906 have been used as the paper's primary sources. Application letters from 32 different Swedes, seeking to join the Congo Free State Army, to the General Consul of the Congo Consulate, Hans Hugold von Schwerin, have been used as primary sources, and constitute the basis of the paper's analysis. The letters arrived at the Congo Consulate in Sweden between 1895 and 1906. The applicants were all men of different social classes, and were between the ages of 20 and 30 years old. Their chief reasons for applying were primarily for own financial gain or because they did not get a chance to serve in the Swedish army.

The companies of today compete about the consumers? attention. In a society where the speed is increasing and the trends are constantly changing the marketing of today will soon be obsolete. This is something that is clearer in the fashion business where the consumers always are looking for news at lower costs. It?s no longer an economical question to be able to wear the latest fashion trends, the availability of cheap fashion clothes is constantly increasing.

Early during my education to become an afterschool-teacher a concern was raised that afterschool-programs will continue to be seen as an institution for childcare services. In this experience-based essay, I discuss what I see as the coreproblem: the free- and planned activities. What do the free- and planned activities actually mean for children's development and what is it that determines how much space the various activities will be allowed to take?In my attempts to answer this question, I go through the concept of leisure, the importance of children?s play and adults responsibilities in children?s play, what the different policy documents say about children?s play and the creative work, staff skills and theoretical and practical knowledge. I question whether I was right in the story that I begin this essay with, and conclude that it is more difficult than I previously thought to find an answer to the question..

Purpose: The purpose of the study is to find out what mathematical content primary school children encounter in their free options at school.Through observation, the study defines mathematical areas that primary school students encounter in their free options at school. We want the study to show the reader the mathematics that students continuously meet without associating it with regular mathematics as taught in school.A number of mathematical areas have been defined in the analysis of the observations. These areas have subsequently been discussed more thoroughly. Finally, the areas have been arranged in a grid system to clarify the results.In our study, we have discovered that mathematics exists in all the observed situations the students participated in.We believe that observation as a method can give teachers a tool for helping students associate practical actions during their free options with the more theoretical aspects of formal teaching of mathematics. We discuss this further in the study..

A range of public health and animal welfare problems has been shown to be associated with free-roaming dogs. With a high density of free-roaming dogs and with a major tourism industry, Samoan tourists are likely to be influenced by the presence of the dogs. The tourists are mainly from the Oceanic region; with New Zealand and Australia as the biggest contributors. The aim of this study was to examine the potential impacts of dogs on visitors to Samoa. A questionnaire was handed out to 281 visitors all over Samoa, collecting opinions and information on visitors? experiences and behaviour regarding the Samoan dogs.
