Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

The building and plant sectors represent a large part of Sweden?s energy use. Putting energy requirements in public procurement as a tool for reducing energy consumption in the building and plant sectors is therefor an opportunity that operators can take advantage of. The aim of this thesis was to map the energy requirements in procurement that operators in the public sector use today in building and plant projects. The analysis was made with respect to if the energy requirements corresponded to the parts with large energy use in building and plant projects and also in which way energy requirements in procurement are written in the contract.

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

The environment that surrounds us affects us all. Research has shown that we feel physically and emotionally best in natural environments with greenery or water elements. Urban environments are likely to be more stressing then natural environments. How we experience specific elements, as water, of an environment is not as much investigated. There is a need of further knowledge for us to fully understand the interplay between our senses and the environment. Human beings have always been depending on water and the search for it has characterized our deeds and doings through out evolution.

The purpose of this study was to investigate the kind of treatment strategies used by Swedish Veterinarians with cattle practice when treating calves with symptoms of pneumonia. A questionnaire, consisting of seven questions, was sent to one hundred veterinarians who have had practice with cattle and are employed by the Swedish Board of Agriculture. The survey was answered by a total of 73% of the Veterinarians. Of the respondents, 73 % use Penicillins as their first choice of drug for treating calves with symptoms of pneumonia, and as their second choice 64 % use Tetracycline. Supplementary treatment such as NSAID (non-steroidal anti-inflammatory drugs) and/or SAID (steroid anti-inflammatory drugs) are used by 97.5 % of the respondents.

Summary:Teenage girls? choice of dropping out or complete a treatment.The purpose of this study is to investigate, from a client?s perspective, why teenage girls (age 13 to 17) drop-out or complete a treatment at Familjehuset in Karlstad, Sweden. We also want to investigate if the teenage girls? experiences coordinate with the social workers opinion of why the teenage girls choose to drop-out or complete the treatment. Earlier research shows that many factors influence the client?s choice.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Knowledge regarding pain and pain treatment is an essential part within nursing that a nurse is responsible for. Earlier studies have shown that lack of that kind of knowledge often results in inadequate treatment for pain. The purpose with the study was to describe nurses? knowledge regarding pain and pain treatment at a medical unit in a hospital in central Sweden, and to see if there was a distinction in knowledge related to professional experience. Data was collected through a questionnaire with questions referring to pain (6 questions) and pain treatment (6 questions).

The purpose of this study was to describe the school situation of adolescents who were subject to multisystemic therapy in Sweden, and also if a change could be measured after treatment. Factors that preceded the need for treament were also investigated. The sample consisted of 83 adolescents, boys (65 %) and girls (35 %), with an average age of 14 years. The method used was a secondary data analysis using pre-treatment- and post-treatment data collected from a 7-month follow-up conducted by Lunds Universitet. Results showed that the adolescents were low in school performance and high in truancy at pre-treatment.

Approximately one third of all patients in primary care have a psychosocial component to their illness that requires adequate professional treatment. However, primary care is insufficiently prepared for these patients. The aim of this case-study was to evaluate a pilot project in primary care offering psychotherapy as a treatment alternative. The data collected includes 1) data from 352 referred patients regarding demographics, diagnosis, treatment duration and pre- and post health status, 2) a patient-satisfaction questionnaire and 3) interviews with six therapists and five medical doctors. The treated patients improved significantly and showed a high degree of satisfaction.

The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

The purpose with this essay was to study how the social work is shaped in the methadone programme and how the staffs treat and work with the social integration for the patients.We have studied the experience of a medical assisted treatment from two different treatment clinics and focused on their treatment programme. We have chosen to focus on the social aspect but we have also been taking part of the medical treatment - the methadone. In order to get a bigger picture of our problem area we also studied how Sweden's narcotic politic is constructed and how a narcotic life could look like before the entrance in the program. We describe this with the help of the theory about the narcotic carrer and the society's view on a normal living..
