The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.

This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.

The aim of this study was to, on the basis of normalization and autonomy; investigate how staff working in group homes discusses about sexuality of people with an intellectual disability. Our study was based on ten semi-structured interviews of both care staff and heads of group homes to get responses from different levels within the same organization. The empirical material was analyzed through the theory of social constructivism, which focuses on how we construct the world through interaction and language, and the normalization principle whose goal is that all people with developmental disabilities should have the opportunity to live like all other people. We view these theories as useful to gain understanding of the questions in our study. The result of this study showed that the subject only comes up for discussion when problems arise, that the communication on the subject is inadequate and more discussion is requested.

Differences between groups or individuals in a society with regards to access to information and communication technologies (ICTs) are known as the digital divide. The digital divide pertains to differences in physical access to computers and the Internet as well as knowledgein using technology. Important factors affecting the digital divide are disabilities, age, gender, socioeconomical background, ethnicity and geography. The digital divide appears on several levels: internationally, nationally, regionally and locally. Individuals who, for some reason, have limited or no access to information and communication technologies risk, among other things, to experience social exclusion.

The purpose of this study was to try to understand the Swedish population regarding the perceptions of the Swedish welfare system, based on the reactions that occurred after Sweden's Prime Minister Fredrik Reinfeldt's statement about raising the retirement age. Our results demonstrate that the reactions on changes in the pension system in fact rooted in a safety factor and not the change in the pension system itself, through which the Swedish welfare system acts as a safety net for the population. Further the results shows that these safety factors create a form of egoism. With an interaction between empiricism and theory, where the starting point of the material was of an inductive approach, the material abstracted into different levels from which the result emerged. The focus of this study lies in the understanding of how human beings act according to one's need for security in major changes, which may be of importance to a comprehensive understanding of changes in social structures..

This study focuses on how the idea of sustainability is dealt with by companies, how the idea changes when moving through a company structure and how the different individuals interpret the idea. To date, many different studies have been written on the subject of sustainability, but few share the perspective addressed in this particular study. This case study was formed at a paper mill in the central part of Sweden. Semi-structured interviews with employees working on different hierarchical levels, within the same company, were chosen in order to get an insight into how the idea of sustainability is implemented throughout an entire company. The interviews have been transcribed to help identify contrasting patterns.This study has shown that the idea of sustainability, and its context within society, differs from how the idea is perceived in the organization.

The natural disasters of recent time have caused the people of Sweden to donate very large amounts of money to different fundraising organizations. With this in mind, we found it interesting to examine the extent of disclosure in the annual reports of the Swedish fundraising organizations. Thus, the purpose of this study is to identify which factors that influences the extent of disclosure of accounting principles in the annual reports of Swedish fundraising organizations. To fulfill this purpose we conducted a content analysis of 149 annual reports from Swedish fundraising organizations. To help us explain the levels of disclosure we applied stakeholder theory, institutional theory and legitimacy theory.

Biological diversity is one out of four dimensions, characterizing the subject of Biology ac-cording to the school curriculum. As a concept, biological diversity had its break through at the UN environmental conference in Rio de Janeiro in 1992, where the convention about bio-logical diversity, named CBD, was signed. According to the convention, almost all the na-tions of the world have engaged themselves to preserve the national diversity of species, in-cluding the diversity of genetics and ecological systems.This thesis focuses the biological diversity from the perspective of school books. The aim is to find out how the biological diversity is presented in biology books for students aged 12-15 years.In 1994, the current Swedish secondary and high school curriculum called LPO-94 was pre-sented. The biology books used in this study were published between 1994 and 2007, all of them exist in many editions and are published by three different publishers.The conclusion of the study is that all the biology books that were examined have reached different levels of the development in the field of biological diversity..

The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.

This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

The purpose of this study was to examine children's participation in court proceedings on supervised visitation and to analyse the descriptions of children in court verdicts. Eleven verdicts concerning supervised visitation resolved in 2014 were collected from two district courts in Stockholm County and studied with a qualitative textual analysis. The material was analysed with participation levels influenced by the ladder of participation for children developed by Roger Hart and with the theory of sociology of childhood. Our findings showed that children's opinions were mentioned in eight of the verdicts. In four verdicts the children's will influenced the courts decisions.

Our aim with this study has been to show the central factors that we consider have had animpact on public libraries in the "information society". We have studied two communities in the south of Sweden, Ronneby and Sölvesborg. These two communities have both started a development to the IT society, a society where information plays a great role, where the technique is the tool that supplies information.Ronneby community had early the aim to be the chief Swedish information center. A priority on information technology has therefore been obvious for them. Sölvesborg community has had another method and time schedule towards the IT society.We have been studying the documentation of aim and the strategy for IT development in different levels.

Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

This thesis examines the process of securitization of the environmental issue in the United States. By using the theories of sectoral security and securitization by Barry Buzan and Ole Waever, commonly known as the Copenhagen school we go beyond the traditional security frames and examine where the environmental issue in the United States stand today within the securitization spectrum. The securitizing spectrum includes three levels in which an issue can be place: non-politicised, politicised and securitized.The problem, which we wish to address, is if there is a movement of the environmental issue in the United States towards becoming a securitized issue. In the light of these circumstances we also wish to explore who is behind the movement and also find out where the issue stand today. We do believe that Al Gore is a securitizing actor and examine his role in the movement of the environmental issueWe have come to the conclusion that there is an ongoing process of securitization in which the environmental issue have moved from being politicised to becoming securitized..
