5-hydroxytryptamin (5-HT) is biochemically derived from Tryptophan. Kynurenic acid and quinolinic acid are also known metabolites of tryptophan. 5-HT is considered to play a role in depression and today selective serotonin reuptake inhibitors (SSRIs) are used for treatment of depression. 5-HT may also play a role in pain perception. The aim of this study was to investigate whether a supplement of tryptophan may affect conditions such as depression and/or pain.

In 1998 Sweden accepted the Treaty of Amsterdam which contained a development of the common foreign and security policy (CFSP) towards a European security and defense policy (ESDP). This thesis aims at studying the decision making process behind the Swedish foreign policy decision to further develop its security policy within the European Union. The purpose is to explain which factors and conditions that did affect and influence the Swedish foreign policy decision. The research applies foreign policy analysis, a theoretical perspective that analyzes both domestic and international conditions using different levels of analysis. The research methods being used has been qualitative as well as quantitative, complemented by interviews, since the research is a process tracing case study.The thesis conclusion is that the Swedish decision is explained by several factors.

The aim of this study was to investigate the possibility of performing inter-species embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.

The aim of this study was to examine women shelters conditions as an organization and how these conditions affect their work with children who have experienced family violence and live in their shelters. In order to achieve a more profound and comprehensive view of the women shelters and their work with these children we selected to execute a qualitative method with semi-structured interviews with collaborators from nine different shelters in Sweden. We found that the women shelter as a non-governmental organization was bicameral and complex where their work with children distinguishes on several areas. We discovered that the women shelters were an organization, affected and formed by its environment. From our empiricism we could distinguish differences on a municipality level where collaborations with schools and social services occur in a resource guided hierarchy which influences the women shelters work with children.

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

This study aimed to explore the perceived role and mandate of civil servants employed in municipalities in Kronoberg county. The study aimed to answer the question whether civil servants engaged in municipal economics have different perspectives on their mandate and role based on how said civil servants implement and manage policy tools available in Swedish municipalities. The study aimed to through policy tools theory explain how civil servants through four categories view the policy tools employed in the municipality. The study is based on the reasoning that policy tools influences exercise of authority that in turn influences view on policy tools. In order to study civil servants perspective on perceived mandate and role interviews were conducted with a sample of civil servants from each of the eight municipalities in Kronoberg county.

The purpose of this thesis is to look into the knowledge city concept and the preferences and requirements of companies on such a city. Furthermore, suggestions of ideal conditions in a knowledge city are proposed. The thesis has been conducted through a qualitative approach where a deductive procedure has been implemented. In order to examine knowledge cities, Barcelona has sketchily been looked at as an early example of a knowledge city, whereas a more exhaustive observation of Copenhagen was conducted. Since the concept of knowledge cities is a rather new phenomenon, models from several disciplines constitute the theoretical framework.

The aim of this study was to investigate how school counselors experienced collaboration with social services and whether they felt they have the ability to improve upon this collaboration. The empirical data consists of qualitative interviews with eight school counselors from public schools, ages 13 to 15, in eight separate municipalities in the Stockholm area. The main results showed that the school counselors recognized the positive benefits from collaboration, but that they in practice experienced difficulties turning this into a high-quality collaboration. The school counselors experienced that due to uncertain expectations in the collaboration it led to unclear distribution of areas of responsibilities. The school counselors expressed small or no possibilities for them to improve upon collaboration but pointed out that higher commitment and a positive attitude are valuable attributes to improving collaboration.

The meaning of the concept of psychosocial treatment is ambiguous. The purpose of this study was to examine how professionals within some care institutions, which provide methadone, buprenorphine or naloxone treatment, regard and carry out the psychosocial features of such treatment. Central issues discussed were; how personnel approach the psychosocial features of the treatment, what personnel regard as a focus in the psychosocial treatment, what conditions personnel consider affect treatment positively in order for it to be successful and how personnel see the relation between the medical and psychosocial features of the treatment. The method used was interviews with nine professionals in six qualitative interviews. The theoretical perspectives and concepts used in our analysis were; the theory of biological dependence, an organizational perspective, Prochaska and DiClemente's Stages of Change Model, the concept of individual reality and the concept of marginal conflict.Results show that the conditions most important for successful treatment are; that the patient has a place to live, an occupation, motivation, that the patient take responsibility for his/hers progress and have realistic expectations about the effects of the medicine.

Ear piercing performed in hairdressing salons and jewellery shops using a piercing gun has been set aside from the obligation to notify the local environmental and public health authorities, due to the use of disposable cassette with the piercing gun. According to the Swedish environmental code each practitioner are required to prevent any health hazards arisen from the operation. Local bacterial infection is the most frequent complication associated with the ear piercing procedure and to prevent the potential risk of such an event, hygiene conditions in both the premises and in procedures are essential. The purpose of the report was to examine the presence of ear piercing practitioners in Umeå and their current hygiene conditions. The study consisted of interviews with employees and managers on site whose answers was evaluated and compared to the general recommendations of The National Board of Health and Welfare.

The functionalism started in southern Europe after world war one and got its breakthrough in Sweden with the Stockholm Exhibition in 1930. Poverty caused many people living in overcrowded conditions which the functionalists wanted to change by using less expensive materials and giving healthier living conditions to the people. The industrialization brought new materials and working methods which made this possible. The Swedish functional style is recognised by its light plaster facing and nearly horizontal roofs. Also the garden design of that time was influenced by the functionalistic ideas. The garden was now introduced as a pleasure garden for not only the rich but for everyone.

This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented. Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.

It´s important when you are about to build a new stable or just increasing your production that you choose the right housing system and that it fits your own farm. In this study I have put together facts about different housing system for fattening bulls in order to get a clearer picture of witch system is the most suitable for my own farm depending on the conditions I have. The background of this work is my own interest for breeding bulls and I will hopefully increase my own production. Due to this I wanted to learn more and increase my knowledge about different housing systems. Through a literature study I have found out the facts about the housing systems I find suitable for housing bulls.

There is always an endeavor to govern the initial products in the plant cultivation with precision in order to keep down the expenditure and in order to decrease environmental impact. Initial phosphorus fertilizer can then be one possibility in order to keep down the fertilizer cost and to decrease environmental impact. This exam study includes a literature study about location of fertilizer and which effects this give and two field experiments. The aim with initial phosphorus fertilizer to autumn wheat is to accelerate the root growth and to give the crop a big root system before the growth stagnates before the winter. Easy to access phosphorus favours the root growth.

Title: Why Great Britain? ? Swedish Encyclopaedias and the Explanatory Perspective of History, Essay in History AbstractIn my essay I describe how Swedish 20th century encyclopaedias interpret the coming about of the British Empire, the overall purpose being to establish a pattern of evolution in terms of historical understanding on the part of the encyclopaedic literature. Firstly, I have tried to determine whether the presentations at all constitute explanatory efforts. In those cases where they do, I have sought to ascertain whether the reasons put forward are to be understood as structural and stable, or as matters of less permanence. I have also tried to link these interpretations to significant ?constructions? of history ? i.
