This thesis has been written within the research project ?Tillfälligt Uppbrott?, which concerns youths who have run away or been thrown out of their homes. The project is based on a na-tional poll among more than 3000 high school students. Our purpose has been to study youths who have left home and their own experiences. We have looked at all the question-naires in which the youths stated they had left home and focused on their answers to five open questions.

 The purpose of this essay is to analyze and understand which difficulties that e-company's struggles with the most, and what their strategies are to overcome this problem. Sales of clothing through e-commerce have made the shopping experience faster and more comfortable, but on the other hand it has created a couple of problems which makes a big difference in the purchase of clothing, we are partly talking about the absence of the testing opportunity. To not know whether or not the shirt or pants will fit, leads customers to a game of gamble every single time they purchase a garment. Another problem which makes customers nervous before a purchase is the absence of a physical salesperson. This might lead customers to question whether or not the company exists.

The aim of this thesis is to identify some of the obstacles to trade, that occurs on the common market, and to analyse the errors that still occurs in the national authorities application of the principle of mutual recognition. Is the principle of mutual recognition sufficient for the creation of a common market, or is there a need for additional measures to cope with the obstacles to trade that still exists on the common market? The problems related to the incorrect procedures of the national authorities and the fact that undertakings prefer to bring their products in to line with the rules of every single member state must be solved, if the principle of mutual recognition is to become trustworthy. On some areas, harmonisation ought to be chosen above the principle of mutual recognition, but in other cases an increased administrative collaboration, mandatory training for the national authorities or information campaigns intended mainly for undertakings could be the answer. The possibility to help undertakings to sue member states for damages should also be investigated.

In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.

The construction industry depends on functioning logistics; if the logistics isn?tworking the construction site will risk to be interrupted due to material shortages orproblems with deliveries. Despite this, the construction industry is battling logisticproblems daily. This problem is very time consuming and costly for the companies.These theses are written for Peab Bostadsproduktion and investigate if it is possibleto focus on logistics earlier in the building planning process to reduce the problemsthat occur. Peab has partnerships with three companies that could be helpful for themin the work of reducing logistic problems.

The purpose of the essay is to examine how issues concerning gender equality are perceived and to show what areas are defined as problematic in different discourses. It also raises the question of who is defined as responsible for dealing with issues concerning gender equality in these different contexts. Theories used are the gender system and intersectionality. The study builds on a mapping of a company that is active nationally and internationally, with emphasis on the problems that can arise when these two social contexts meet, with a special focus on cathegories such as gender and ?Swedishness?.

The aim of this dissertation is to examine why smaller municipalities[1] in Sweden experience difficulties when implementing the 16 environmental objectives that are designed to solve Sweden's environmental problems.The theoretical framework used for this dissertation is implementation theory which provides three conditions that need to be met in order to have a successful implementation.  These three conditions have shaped the research questions that examine if Torsby municipality has the "understanding," "ability" and "will" needed to implement the decision correctly.  The dissertation employs a case study method to examine why Torsby municipality has experienced difficulties implementating the target: programmes and strategies for planning, which is an interim target to environmental objective number 15: A good built environment.  Qualitative text analysis and interviews with politicians and civil servants from Torsby municipality and the county administration board of Värmland have been conducted in order to answer the research questions.   The material used for this dissertation is mostly from the government bills that are the foundation of the Swedish environmental policy and the documents and reports about the environmental objectives that the National Board of Housing, Building and Planning (Boverket), the Swedish Environmental protection agency (Naturvårdsverket), and the Environmental objectives council (Miljörådet) have released.The result of this dissertation supports previous research which has shown that smaller municipalities have problems implementating the environmental objectives due to a lack of financial resources. This dissertation also shows that the problems can be due to a lack of understanding the purpose of the objectives.  This leads to a lack of political will to implement the objectives.  Since the municipalities do not have the political will to implement the objectives the appropriate resources needed for a successful implementation are not appointed and therefore the municipalities are not able to fully implement the environmental objectives. [1] Municipalities with less than 20 000 inhabitants..

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

A current debate is going on in Sweden about the health-care organization, how it is structured today and how it should be structured in the future. Despite major changes in the county council structures, they still got problems with for instance economy and the providing of staff. As an answer to these problems new solutions are being developed.In this thesis I examine such a solution consisting of cooperation between county councils. The aim of the thesis is to examine how and why the county councils in Sörmland and Västmanland have made a decision regarding cooperation over the administrative border.My contribution is to construct a model over change and decision processes that can be used in other cases as well. The conclusion is partly that the decision to cooperate is built on changing structural factors, such as economy, demography and medical development.

Sexual dysfunctions concerning women with multiple sclerosis (MS) are common. Since the disease preferably affects young individuals when establishment of family occurs, the result of these problems have a great impact on the individual and her family. The purpose of this literature review is to throw light upon these problems and respond the questions if the nurse may be the right person to give sexual counselling and in which way this may be done. The theoretical framework was Antonovsky´s concept "sense of coherence". The result is presented in four themes: bodily aspects, social aspects, information/counselling, and practical implications for nurses.

During the study's first stage we noticed that the Swedish term ? utanförskap? was constructed for political purposes, the term?s ambiguity what was first raised our interest. Therefore the aims of this study was to examine how social workers at the social welfare office and the labor market related project Framtid Kronoberg  as well as politicians within the administration of Arbete & Välfärd (Work & Welfare) relates to utanförskap as a social phenomenon. The study?s second aim was to examine how the aforementioned persons consider utanförskap to be counteracted among young adults.

In this trial we used QualispermTM as an objective method of measuring stallion semen. Samples of semen were analyzed before and after centrifugation. Motility and concentration were statistically analyzed. During the trial all the objective mesaurments were compared to a subjective method. The advantages of QualispermTM compared to older CASA- systems is it´s ability of measuring a greater amount of spermatozoa while it also grades them into different subpopulations. These subpopulations have different qualities that decides their capacity of fertilization. The results showed that this objective method might be used practically. Although, there are still some disadvantages, such as high costs and the necessarity of accurat training of the handler. If it´s possible to prove further relevant results that also are statistically correct, this could prove the usefulness of QualispermTM as an objective measurment method in the daily work at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work for an improved horse breeding in Sweden, improving both in quality and economically..

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

There has always been global warming on earth and it is because of it that the earth is inhabitable. Without global warming the temperature on earth would be around -18 ° C instead of today's + 15 ° C. Global warming is generated by greenhouse gases like carbon dioxide and methane which trap long wave radiation in the earth's atmosphere. The problem today is that the global concentration of green house gases has significantly increased since the 1750's as a result of human activity. Today's values widely exceed the preindustrial values.
