Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

  Aim. The aim of the study was to describe how nurses in home care experience to pursue palliative care in ordinary housing. Methods. The study had a descriptive design with qualitative approach and was carried out through semi-structured interviews with 14 nurses in home health care from two medium-sized Swedish municipalities. The material was analyzed with manifest and latent content analysis. Findings. The underlying theme that emerged in the study was: Working with palliative care in the patient´s own homes is positive but challenging. Informants describe among other things that they perceived palliative home care as meaningful and that relatives have a central role in the palliative home care since they are close to the patient around the clock. The stress that emerges from the heavy work load and the long geographic distances are described as strenuous and to affect the care in a negative way. Informants describe the home environment as challenging as it is often not adapted for care and the collaboration with the palliative team is described to be experienced as both positive and negative.

The purpose of the study was based on scientific literature to describe the quality of life of persons who have undergone a total hip replacement. The method was a descriptive literature review. The results showed that pain was the most obvious change after surgery. Mild pain before surgery was strongly associated with mild pain after surgery. But despite less pain were experienced early, it took 1 year to achieve the full benefits of improved physical function.

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.

ABSTRACT. Introduction: Human Immunodeficiency Virus (HIV) is a retrovirus which occurs worldwide and spreads between humans mainly through sex, from mother to child, blood and blood products and between injecting drug users. After been infected with HIV for a couple of years the final stage of the infection progress into Acquired Immune Deficiency Syndrome (AIDS), and there is no cure or vaccine, only medication that delays the development of the disease. Objective: The aim of this thesis is to examine the preventive work against HIV in Sweden, the groups at risk for getting infected and to highlight sexual attitudes and behaviours among adolescents and young adults. Method: A literature based study method was used and the material is based on scientific articles and reports from active actors within the field of HIV prevention.

Introduction: Workplace health promotion is important for both the health of the employee and the profability of the company. Among other things the psychosocial work environment tends to be related with motivation and well-being at work. Employees who experience work motivation and job satisfaction are at less risk of illness, which may also result in reduced absenteeism. Aim: The purpose was that of a smaller pilot study examining a qualitative methodology to obtain detailed and concrete information about the blue-collar employees' views on what helps or impair the psychosocial work on the logistics company. Method: A qualitative approach where semi-structured interviews were held with four focus groups was used.

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 main purpose of this thesis is to examine the process of selecting films at Bibliotekstjänst and at Swedish public libraries. The tools that have been used for analysing and interpreting the results from the interviews and the questionnaire are theory-based models describing the selection process concerning film and Carl Gustav Johannsen?s quality definitions. The result of the investigation shows that Bibliotekstjänst doesn?t really work with any quality definitions in their selection process.

Literature describes what it is like to be a leader in the healthcare and what is looked upon as the most characteristic quality for female leadership. Women often use a leadership technique that motivates the employee and they allow themselves to develop a humanitarian leadership. The aim of this study was to describe female head nurses? experience of their leadership in healthcare. The collection of data has been carried out from interviews.

Considering water quality, landuse and reducion of wetland area in the watershed of Tidan, areas witch are in need of constructions to improve the water quality are identified. Constructions are suggested to be located within the smaller streams in the watershed, so that the water is treated before it reaches the stream Tidan..

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

The aim with our paper has been to get a picture of which factors one of the heterogeneous group that we've chosen of old persons, 75-90 years, in Scania, in south Sweden, have experienced to be of importance for their life quality today and what they wish to preserve of their actual life style when they eventually shall use the elderly care. Also how their individual life course has influenced their experience of the quality of life.We found this subject interesting as the group of old people in the society is constantly increasing and when the group becomes bigger, then greater demands will be put on the elderly care. We have proceeded from a standpoint that all people are unique individuals and that people become what they are from their life histories and from the choices they have made during their life. We have used the life course theory that says that one should see the individual in his/her wholeness and the whole life history of a person in order to understand him/her. We have also studied earlier research concerning the different determinants of the life quality.
