A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

This master thesis concerns itself with the actual work of knowledge workers, consultants to be specific. We have through interviews and observation tried to get inside of the ?black box? of the consultants firm Consult in an effort to describe their way of working through a theoretical framework. In this framework we attempt to combine knowledge work theory with that of organizational development, OD. We try to introduce the situation of the individuals we study, the consultants, through Alvesson (2004) and Løwendahl (2005).

The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.

The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.

This master's thesis focuses on the development of a strategy for aninformation service in the area of digitization of cultural heritage andresearch, with a web based platform as implementation of the strategy. Viathe platform, digital collections and research are presented and shared.Services around the platform are provided. Support activities comprise thewhole chain of digitization, from digitization to archival of the digitizedobjects. The information service aims for a new approach to combine ICT andestablished research; research and industrial practice were combined andcooperation of participants from various backgrounds was enabled. Thestrategy and organization of such information service was described using a?quality management system?, standard ISO 9001.

This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.

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 purpose of this study was to obtain an understanding of how the employees at LFV Group Swedish Airports and Air Navigation Services (Luftfartsverket) manage to combine work and family, and put this in relation to the concepts of employer of choice and socially sustainable development. Qualitative interviews were carried out with 23 randomly selected participants at the three largest places of work within the organisation. The results showed that the combination of work and family mostly could be managed but that factors like high workload and feelings of stress affected the participants in a negative way. The main measures facilitating the combination of work and family were shorter working hours and support with domestic chores. LFV can partly be considered an employer of choice when it comes to family friendly benefits but changes could be made for further improvement.

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Counselling is one of the most commonly utilized tools in the work place. The purpose of this paper is to explore how four employers utilize early counselling sessions related to absences due to illness. A qualitative research method has been used and four human resource managers have been interviewed. The research questions have been divided into three categories: the counselling structure, the counselling model and the counselling dilemmas. The interviews have been transcribed and processed through these three categories.
