The aim of this Master's thesis is to investigate the library needs of distance students. This user study has a student perspective and concentrates on the main question of which way library needs might be expressed by distance students. Associated topics addressed by this study include; the problem of learning centres lacking their own library support, how distance students look upon library support as a concept and whether distance students prefer public libraries or university libraries, and why they make this choice. These questions may give the answer to how distance students deal with information literacy. Theories chosen by the study are in the fields of pedagogical and library science, the social cultural theory by Roger Säljö and in Tom Wilson's theories on user studies and information needs.

The purpose of this study was to, from the teacher's point of view; discover pupils with reading difficulties in connection with text assignments in mathematics, the teacher's support for these students, if difficulties coincide and whether it's the mathematics teacher's responsibility to make sure pupils with reading difficulties develop their reading ability. The study is based on a qualitative method and five semistructured interviews with mathematics teachers and one language support teacher.The result shows there is a strong connection between the pupils' reading ability and their ability to manage text assignments in mathematics. A weak reading ability affects the pupil in a negative way when solving text assignments in mathematics due to wrong reading technique if the teacher is absent. It is not unusual that reading difficulties and mathematics difficulties coincide. The teacher's most important role in the learning process is to teach the pupils understanding about the reading technique in different ways and to give the pupils opportunity to get spoken texts.

Actinomycosis is a rare, deep-seated infection of the jaw of cattle that include the progressive enlargement of bone structures. It is caused by Actinomyces bovis, a gram-positive rod found as a normal commensal of the alimentary canal in otherwise healthy animals. This paper shortly describes Actinomyces bovis and its ability to cause "lumpy jaw" or actinomycosis in cattle. It will describe its pathogenesis, diagnosis, treatment and some clinical presentations. The incidence of symptomatic actinomycosis infection is quite low in Sweden today.

Rheumatoid arthritis (RA) is an autoimmune disease, which affects mostly women. RA is also a chronic disease and the treatment is focused on moderating the immunological process. RA-patients experience daily pain which affect their prosperity. The aim of this literature study is to illuminate some factors that influence the well-being of patients with RA. The factors that have been studied are pain, nutrition and need of knowledge about nutrition.

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

Background: Documents and legislation inform us that parts of the public health service of Sweden, at a political level, aim to support people?s sexual health. Statistics show there has been an increase among young woman, seeking help for sexual pain during intercourse. The diagnosis that the media has come to observe lately is vulvar vestibulitis. In general there is a lack of knowledge about the existence of this state of pain and its causes, which impacts woman to get appropriate help and support in time.

Heart failure is an illness that requires life-long treatment and often affects everyday aspects of a person?s life. Self-care is a significant part of the treatment. Good self-care resources make it possible for people with heart failure to make the lifestyle changes they often need to maintain or improve their level of health. Self-care means having knowledge of and being able to recognize the symptoms and signs of deterioration that can occur with heart failure, so that the person can take appropriate measures ? and it also means knowing when it is time to seek professional help.

Chile and Santiago are struggling with heavy environmental problems as a consequence of urbanisation and industrialisation. In the Santiago region the air is seriously contaminated and most of the rivers are classified as heavily polluted.The aim of this thesis is to survey the industrial fluid waste situation in the Santiago region and to make suggestions on technological improvements or process changes. The purpose is also to study five different enterprises more closely and to give more detailed suggestions for improvement. Another purpose is to summarize relevant Chilean legislation.Information, provided by the supervisory authority, about the release of industrial wastewater to rivers has been analysed. Deep interviews have been made with authorities and consultants.

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

The aim of this essay was to study how the communities work with groups as a support to children with addictive parents, and to increase my understanding of the groups meaning as a support. My main questions have been: How are the child group sessions formed? What kind of experience does the group leaders have regarding their functions? The study is a qualitative investigation that has been turned to prefessionals in the subject area and  is based on 6 interviews and secondary sources. The material has been analyzed from a narrativ theory as well as a salutogent perspective. Research shows that children growing up in an addictive environment often have decreased psychological health and are overrepresented amongst those who developed a future addiction.

Jönköping Small Animal Hospital is today the only clinic in Sweden to offer radiation therapy as a treatment of tumours. The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.

The purpose of this thesis is to investigate the view on the personal encounter between staff and visitors in public libraries in order to detect possible differences between the two groups in order to see if the personal encounter as such could be used in order to market libraries. We believe that social competence must interact with the initial personal encounter in order for the visitor to experience the visit as positive. We have based the theoretical framework on Erving Goffman?s theory on social interaction, as well as on Christian Grönroos? theory on quality of service and marketing. We use the following questions: How do library staff view the personal encounter? How do library visitors view the personal encounter? How does the library staff?s treatment affect the visitor?s view of the library?Are there any differences in view between visitors and staff concerning the personal encounter? If so, what kind of differences are they? Using qualitative interviews, we have interviewed nine visitors and six staff members at two public libraries.

Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.
