Det finns ett stort intresse i miljövänlig framställning av bioenergi, och där lämpar sig biogas mycket väl. Inom lantbruket har vi goda förutsättningar för biogasproduktion och trots ett stort intresse för bioenergi finns en tveksamhet ändå. Mycket beror på en tuff marknad med dålig lönsamhet samt ett avancerat regelsystem som måste följas. Tillstånd och stöd måste sökas vilket kräver mycket tid och ett stort intresse.En biogasanläggning klassas som miljöfarlig verksamhet när den överstiger 150 000 m³ i gasproduktion och då krävs tillstånd från länsstyrelsen. Detta är en ansökan som består av tre delar: grunddel, teknisk beskrivning samt en fullständig miljökonsekvensbeskrivning.Det finns en del stöd att söka för bioenergiframställning.

Calculations are an important part of planning around a construction project. From concept to completion of the project calculation is a tool to try to predict the actual cost. During the production stage in particular, deviations occur which makes the actual cost different from the calculations.This thesis is done in collaboration with JM Residential Stockholm. The study includes a cost follow-up in which a comparison was made between the calculated production cost and actual cost for the five projects. The aim of the study was to observe the most common reasons that a project deviates from the calculated production cost and then summing these causes in a number of categories.

Bakgrund: Self-efficacy, en persons tilltro till sin förmåga, är en faktor som påverkar hälsobeteenden såsom fysisk aktivitet. Exercise Self-Efficacy Scale mäter denna egenskap genom självskattning, men har inte utvärderats för personer med schizofreni.Syfte: Att omarbeta Exercise Self-Efficacy Scale för personer med schizofreni.Metod: Deskriptiv design med psykometrisk prövning av den omarbetade Exercise Self-Efficacy Scale. Första delen av studien bestod av fokusgrupper med patienter och personal på en psykiatrisk öppenvårdsmottagning för patienter med psykossjukdom. Utifrån resultatet av dessa utvecklades Exercise Self-Efficacy Scale ? Schizophrenia Version.

Background: With the removal of audit requirement for companies in Sweden from the first of november 2010, a lot of companies has chosen not to keep the audit requirement. So far 57 percent of the small companies has chosen to keep the audit, in spite of that they don´t need to which led us to the problem statement: Which are the factors that affect a small limited company to choose to keep the audit, in spite that now there is a possibility to choose not to use audit anymore?Purpose: The purpose of the essay is to examine why small limited companies choose to keep the audit, in spite that now there is a possibility to choose not to use audit?Method: This research founds itself in a qualitative study with a deductive research approach. We have been studying secondary data in books and articles and preformed 29 phone interviews with small ltd company owners in Sweden. The selection consisted of 14 companies with credit debts and 15 companies without credit debts.

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

SAMMANFATTNINGSyftet med studien var att studera hur sjuksköterskan inom intensivvård använder NuDesc(The Nursing Delirium Screening Scale) och om de anser sig ha tillräcklig kunskap för attbedöma delirium med hjälp av NuDesc.Studien är en kvantitativ tvärsnittsstudie med datainsamling via en enkät som konstrueratsspeciellt för denna studie. Enkäten besvarades av 15 intensivvårdssjuksköterskor på ettuniversitetssjukhus i Mellansverige.Resultatet visade att bedöma delirium på en intensivvårdsavdelning uppfattas avrespondenterna som ganska svårt även om de tycker sig ha tillräckligt med kompetens attanvända bedömningsinstrument NuDesc. Den psykomotoriska förlångsamningen tillsammansmed hallucinationer/ illusioner uppfattas av sjuksköterskorna som svårast att bedöma..

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

The purpose of this masters thesis is to evaluate the retrieval effectiveness of three different search engines on the Internet: Google, Yahoo! and MSN Search. We have constructed 25 topics and queries with varying contents, in order to test the width of the search engines as much as possible. In every search we have evaluated the first 20 hits in each of the search engines. The measures we have used are precision and cumulated gain. Precision is based on a binary scale and cumulated gain is calculated by means of a non-binary relevance scale.

The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur). The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas. The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected. The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands. The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.

AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

Trade is the driving force for economic development. A greater equity in international trade can improve the livelihoods and the well being of producers in developing countries. The small-scale farmers have limited resources and have difficulties to get access to the international market. As a result of this, the Fair Trade movement has been developed and has now formed a trading partnership between the producer and the consumer. This study analyses if the Fair Trade movement can be a way for the workers in developing countries to achieve more justice in their production manner in the international trade of cut flowers and continue to be an important competitor of these products, but with better livelihood conditions. My method has been to do a comprehensive literature study of the Fair Trade movement, in which I describe the certification process, and the market of Fair Trade in Sweden.
