Rötning av matavfall ? en studie av metanutbytet hos matavfall förbehandlat med skruvkrossteknik samt vid samrötning med bioslam från pappersbruk
Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.
Vaccinationsbiverkningar hos hundar i Sverige
Vaccinology is an ever expanding field. As a member of the veterinary staff it is important to stay up to date with the continuous new scientific data and recommendations that affect the care that our companion animals receive at the veterinary clinic. This paper presents adverse vaccination reactions, their cause, risk factors and suggestions how we can minimize the risk of adverse vaccine events in dogs. Dog owners in Sweden were allowed to answer a questionnaire about adverse events following vaccination. Lethargy, edema and pruritus were among the most frequently seen adverse effects.
Entreprenöriella team : Varför startas företag i team?
Contemporary society focuses heavily on the individual and this is also characterized by an individual thinking that many people contribute to. This is furthermore shared in the field of entrepreneur research studies where a profound deal of time has been focused on the personal qualities of specific entrepreneurs. However, in modern settings today many corporations originate in a team-based structure, which therefore leads towards a different approach rather than examining exclusively on individuality. Previous research shows that entrepreneurial teams are establishing and growing at a steady pace, yet studies within this field has not developed in an extensive fashion. Entrepreneurial teams can be defined as a group of people who share a common goal, usually consisting of two or more individuals who commenced a foundation from the early stages of that specific firm and who originated an initial idea.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Mötet med föräldrar till överviktiga barn : En intervjustudie ur barnhälsovårdssköterskans perspektiv
Background: Overweight in children is a growing problem around the world. Studies has shown that children suffering from overweight, are at a greater risk to remain overweight as adults as well. Child health care nurses have an important task by trying to motivate parents to better diet and exercise habits for their children. Previous research proves that overweight and obesity in children is a very complex problem which requires a good caring relationship between child health care nurses and parents.Purpose: The purpose of the study was to illuminate the experiences of child health care nurses of meeting parents of overweight children.Method: An inductive qualitative approach was used as method. The collection of data was conducted by using semi-structured interviews.
Biodiversitet av evertebrater på vegetativa tak
In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.
Soil carbon, pH and yield development in a long-term humus balance trial
Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss
of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.
Samverkan mellan nya cementtyper och tillsatsmedel för betongtillverkning
Cement manufacture accounts for 3-5 percent of total global carbon emissions. There is a growing interest in reducing the environmental impact and conserve limited natural resources. In cement production, clinker productions consume 87.5 percent of the total energy consumed in the cement manufacture.Cementa has since many years, focused on reducing the environmental impact of cement production. The work has involved the entire production process from selection of alternative fuels to the development of cement with less clinker content. During 2013/2014, two new types of cement (Bascement and CEM II / B) will be introduced to the Swedish market.
Friluftsvanor -I storstad och på landsbygd
Outdoor recreation habits in metropolis and rural areasThis study aims to examine the perception of nature and outdoor recreation habits from an urban-rural prospective. The urbanization process continues in Sweden and the populations of the cities are growing continuously. Trends to build more compact and ?climate smart? reigns and with this a risk that green areas and areas where outdoor recreation can be practiced are situated further and further away from the urban population. Analyzing the responses from a survey made by the research program Friluftsliv i förändring 2007 we have examined if and which differences exists between urban and rural areas regarding their perception of nature, outdoor recreation habits and factors influencing the practice of outdoor recreation.
The Impact of Customer Orientation on the Business Strategies: the Customisation Case of Nestlé on French and Chinese Dairy Markets
Background: As Porter?s diamond (1990) suggested, the business environment highly influences firms? strategies. Today, most of the companies have to decide their strategy depending from a worldwide business environment. Yet, strategy researches and the growing importance of marketing for business success also show that customer dimension must be taken into consideration. On some markets and in certain industries, the offer is much higher than the demand and then, companies need to attract customers.
Fröskörd av hampa : metoder och tekniker för fröskörd av industrihampa
Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new uses for hemp continue to be identified and this fascinating plant has incredibly versatile applications.In this project, seed production of industrial hemp in Sweden was studied and evaluated. Five different methods are described, four of which are proven under Swedish conditions.
Behandlingsresultat av kliniska mastiter : en studie av mastitbehandlingar utförda i mjölkkobesättningen på Jälla naturbruksgymnasium 1997-2008
Mastitis is an important disease in dairy cattle. It is very costly for the farmers and affects a large number of animals. Few studies have been made investigating the outcome of treatment for acute clinical mastitis under Swedish conditions, and it can be problematic to use the results in foreign studies since both the microbial flora as well as treatments may be different from the situation in Sweden. In this project we have investigated data on clinical mastitis and antibiotic treatment in the dairy herd at Jällaskolan, Uppsala based on recordings during the last ten years. The material includes both Swedish Red (SRB) and Swedish Holstein (SLB) breeds, which have been kept at the farm under similar conditions.
Konstruktion av en fotobioreaktor för odling av alger : ett småskaligt försök
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Economic impact of fertilizers and improved seeds among smallholder farming systems in Central and Western Kenya
In Kenya, many families subsist on agriculture and of the country's around 40 million residents 70% work in the agricultural sector. 50 % of the country's gross domestic production (GDP) comes from farming, and thus the country is largely dependent on income from this sector. Kenya's population has tripled in recent decades, which have led to that food availability is a growing problem.
To ensure food security, it is important that the return from crops increases. The aim of this study is to evaluate what impact the use of fertilizers and improved seeds has for farmer?s economic situation and income generation.
