The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Background: With the increased globalization food prices went down for a while, only to skyrocket to new levels. Prices of organic food, which already were more expensive than conventional, are now even more expensive. The current financial crisis results in reduced consumption which creates a threat to the smaller grocery stores. Globalization and the increased competition have had a negative impact on the environment but at the same time the desire to solve these issues has increased appreciably. The environmental aspect has been given higher priority by the individual, which led to a wider range of organic products and dramatically increased the number of stores selling organic products, leading to a greater competition among the stores selling organic food.  Problem definition: What factors are important for organic retail business long term survival?Purpose: Trough case studies analyze and evaluate the organic niche retail companies? strategies of marketing.Methods: This study is based on both qualitative and quantitative research methods.

The aim of this study is to examine the understanding, preschool teachers, have about their work related to energy conversion in the human body. Through individual interviews, answers have been sought to the following questions: What do the preschool teachers believe they need to know about the link between food and energy? What are the different methods preschool teachers use to workwith the area of energy conversion in the human body?The results show that preschool teachers have knowledge in terms of food and its nutrients as an energy source for the body to cope with. However the more thorough and detailed questions become all the more uncertainty there is about the topic. Preschool teachers on their own initiative do bring up the topic with the children and begin conversations as well as ask questions, perform experiments and demonstrations.

During one week (9-13 May, 2005) the use of veterinary diets for the hospitalised patients att the University clinic was registered. The animal owners were interviewed by telephone six months later about the feeding after coming home. Four out of ten animal owners answered yes to the question if the veterinarian had asked what food their animal normally consumed. Out of 35 animals, 15 (43%) were prescribed to a veterinary diet. Among cats it was 8 out of 14 (57%) and among dogs it was 7 out of 21 (33%). Four animals out of ten were recommended a veterinary diet when going home, but 20% did not follow the recommendation all the way through and stopped feeding their animal the veterinary diet. Reasons that were given was that the diet didn't last the entire period, that the animal didn't need the diet anymore according to the owner and one dog that became to lean when fed the diet. The diagnosis for these three dogs was vomiting, foreign body in the digestive system and bloody diarrhoea.

This study has been done in order to map the supply of vegetarian and vegan food products in Sweden for business clients and consumers. A total of 665 food stuffs were found and classified into six categories. The biggest category was meat substitutes with 302 products and the second largest category was sandwich spreads with 150 different products. Within the remaining categories a varied number of products were found; 86 beverages, 64 cooking accessories, 34 milk free ice creams and 29 plant based yogurts. Of the meat substitutes were 28 only available for business clients.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.

En allergisk person påverkas på fysisk, psykisk och social nivå. Unga vuxna allergiska personers erfarenheter och upplevelser av allergi är relativt outforskat. Syftet med studien är att förstå hur unga vuxna personer med allergi upplever att allergin påverkar deras vardag och hur de förhåller sig till ett liv anpassat efter allergin. En kvalitativ intervjustudie genomfördes med 10 deltagare i åldrarna 18-22 år som hade olika former av allergier. Resultatet visade att allergi har en betydande roll för allergiska personers identitetsskapande och många beskriver en strävan efter att passa in socialt trots sina besvär.

The habits of living are seen as important factors for public health, and are related to the primary socialization. Exercise and food habits are two main factors for development of health or ill health and are both related to the overweight epidemic. The overweight increase among children and youth has been given particular attention. The aim of this study is to examine how 15 year olds Body Mass Index, food- and exercise habits are connected to each other and also how they are related to socialization. The study is a cross sectional survey among 208 pupils in ninth grade, Kristianstad.

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.

This multiple use forestry plan is made on the property Basunda which is located in the southern parts of the province Östergötland. The owners of the property today are Jonas and Ulrik Saanum, but it has been in the family since their grandfather bought it 1933. There is a slaughterhouse on the property in which they take care of domestic cattle and animals from the forest. Jonas and Ulrik are also dedicated hunters. These are the two reasons to why the focus is wildlife and wildlife management. The question at issue of this work is simplified: what demands does the wildlife have; and how will the owners be able to fulfill these, what changes in the forest management must be made and will these changes result in a different budget, compared to the ordinary forest management. This work is based from a freshly made forestry management plan. I based my fieldwork on this plan, but made my own management proposals, that would benefit the game.

In the Maasai Mara National Reserve the native people, the Maasai, have lived for a long time following their own traditions. Their traditional lifestyle is that of a nomadic people, leading their cattle to the best grazing. Sharing their land with a large variation of different animals, one of them being the African Elephant (Loxodonta africana), the Maasi people have since long adapted to a life side by side with these giants, as well as the fierce predators living in the area.The aim of this study is to determine whether the Maasai settlement, known as Boma, has any impact on the elephants in the surrounding area. In order to conclude whether the bomas has an impact or not, observations of the wildlife were carried out. Observations were conducted in two different seasons, in December 2003 and May/June in 2004.

The giant otter (Pteronura brasiliensis) is listed as an endangered species and scientific litterature concerning its biology and behaviour is scarce. The current study observed a group of three giant otters in a Swedish zoo. First the otters normal behaviour was recorded. Then the aim of the study was to see if the otters behaviour changed when given blue mussels (Mytilus edulis). Furthermore the aim was to see if the otters displayed any tool-using behaviour when given mussels.
