Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :

Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.

Hedersrelaterat våld : En studie om socialarbetares förståelse av hedersrelaterat våld

After the honor killings of Fadime and Pela, an extensively discussion started in the media, debating honor-related violence and oppression. This debate also made us, the authours of this paper, to pay attention to the problem.

The study was conducted by four qualitative interviews with professionals in social work with a professional experience of honor-related problems. Through the interviews, the social worker's view of honor problems emerged.

Lakningsförsök med furubarksflis : en utredning om utsläpp av fenolföreningar samt metallsorption

The filters used today to purify water are often expensive and the need to find new filter materials is substantial. Studies of pine bark have shown that this is a material that may be used as an alternative to conventional filter materials, such as activated carbon. However, the study of pine bark has shown that a leakage of phenolic compounds may occur when using the material for water purification. Therefore, the purpose of this report is to investigate the release of phenols from pine bark, in order to evaluate the use of pine bark as a filter material. Another assignment is to investigate the amount of metals adsorbed by the filter material.

Träningsredskap

There are many risk factors involved with a sedentary lifestyle. Deep vein thrombosis (blood clot), circulatory problems and contractures are just a selection of problems you can get by too little exercise. For people who are immobilized because of illness, it can be difficult to get enough exercise and movement to avoid similar complications. Because of most medical supplies on the market today are not optimal for use at home, I have chosen to develop a training device for the lower limbs, adapted for use in a bed, both in hospitals and at home. It is important that the devise can be used in any bed, regardless of headboards.

Förtroendeproblematik för privata pensionsförsäkringar i Ryssland

The first aim of the thesis is to analyse the problems of trust, according to game theory, in the Russian market for private pensions insurance. The second aim is to find suitable strategies to solve the problems. Problems of trust have arisen because, (i) buyers of insurance have had negative experiences when dealing with insurance companies and corruption has decreased trust for all players in the market, (ii) incomplete information makes it difficult to separate honest actors from dishonest, and (iii) dishonest insurance companies do not get punished because of corruption and weaknesses in the law. Mutual risk-sharing is a potential solution as necessary conditions already exist in the Russian society. There are groups who (i) share the same type of risks, (ii) are aware of moral hazards, and (iii) are able to control each other.

Tjuvögon och långskallar : Skolpersonals beskrivning av erfarenheter och ansvar kring barn med sociala problem

The purpose of this study was to investigate how pupils with social dysfunction were defined and described and how the responsibility of the school concerning the needs of these pupils was apprehended. For this matter, in depth interviews with four headmasters and four teachers at three different schools were carried out.The possibilities to help pupils with social dysfunction were regarded as limited due to limited resources. The school can be described, as a huge refined apparatus of classification where some children very early are eliminated and there does not appear to exist any back up plan for these individuals. In this respect the function of the school is very similar to that of yesterdays school where the elimination process worked just as well, the denotations change but the problems remain the same.The material used in this study is too small to make general conclusions but the results give some indication of the problems of the interaction between the school and its staff and pupils with social dysfunction. We strongly believe that the results warrants further investigation as to in what way the school can improve in helping pupils with social dysfunction..

Framtida inhemska proteinfodermedel i den ekologiska fjädefäproduktionen :

Organic layers and broilers will according to (EEG) no 2092/91 be fed 100 % organic feeds in year 2012, which is expected to present problems associated with the specific protein requirements of poultry. This document aims at describing the feedstuffs that possibly may constitute a part of the solution to these problems. Peas, field beans, naked oats, canola, hempseed and sunflower come out as interesting feedstuffs. Biproducts from the milling and dairy industry together with marine protein supplements may be brought to the fore, provided that the demand for organic products will rise further..

Premiepensionssparande : Fondförvaltningsstrategier applicerade på PPM

The everyday work at a staffing agency and how its leaders deal with the problems that appears: A case study at Maxkompetens.The purpose of this paper is to increase the understanding of how leaders at a staffing company deal with the everyday problems that arise from a geographically dispersed workforce.The staffing industry has grown by 30-40 percent annually and has over the past 15 years been the fastest growing industry in Sweden. This shows that the interest and demand for the staffing industry and its activities are now rising at an increasingly faster pace. This is an industry that is operating under specific conditions and with a geographically dispersed workforce. This will make the leaders of a staffing company to an important link between the staffing leaders and the staffing personnel.The relationship between the staffing company's leaders and its personnel is important, but not completely trouble free. Difficulties arise in that the employees may be located in different places and at various client companies with the result that the leaders of the staffing company cannot have a daily personal contact with their geographically dispersed personnel.We have used a qualitative approach on our paper and our empirical methodology has been a case study with ethnography and interviews.

Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.

Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.
