The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and Utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

The formulation of visions into practical projects is an important part of the professional expertise of landscape architects. This expertise includes the gathering, structuring, improvement and Utilization of knowledge. Project models have been developed to provide tools for the implementation and governance of projects, as well as means of learning, reflection and survey of individual projects. The aim of this thesis is to describe some general project models and their theory, and to describe practical, real-life examples of project models used within landscape architecture. Questions asked are: ? How do the processes of idea to construction in landscape architectural projects lool like? Do project models have a relevance for the mission of landscape architects? ? Is a common project model used within such projects, or is the project model varying depending on e.g.

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Higher demands of competitiveness and efficiency have led to increasing sizes of farms, with more land, more capital and more comprehensive logistics. The aim is to gain benefits of scale economies that reduce the production cost per unit. However, a greater extent of the business exposes the farm of increased risk where small deviations rapidly can erase the benefits. A modern dairy farm thus put high demands on the farmer?s ability to coordinate, plan and manage the forage production through the whole process until storage to obtain silage of the desired quality and quantity at the right price. The objective of this study was to design a simple model, i.e.

Övervikt och fetma har ökat lavinartat bland barn och ungdomar de senaste 25 åren. Fetma medför både fysiskt och psykiskt lidande för de drabbade barnen och de löper även en stor risk att drabbas av sjukdom i vuxen ålder. Prevention av övervikt och fetma är därför av högsta vikt. Forskning och olika studier kan bidra med utveckling av behandlingsmetoder, hitta nya orsaker och samband till varför fetma uppstår. Syftet med denna studie var att utvärdera om det finns samband mellan RQ-BMR (respiratorisk kvot, basalmetabolism), antropometriska mått och kroppssammansättning hos överviktiga barn och ungdomar i åldrarna 10-13 år.

The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector. This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the Utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

For many providers of ERP-system, Poland is one of the most valuable markets in Central andEastern Europe. The Polish market for ERP-systems is still a growing market, especially; wecan see the low Utilization of ERP-systems among small and medium-sized enterprises. Thisis due to several factors, primarily the cost of implementing the system and the necessary infrastructure.Subsequently due to the lack of knowledge, where there is no sufficientknowledge of the benefits arising from the use of an ERP-system in their business, and thereis a fear within the companies that its business would start stagnating.This paper investigates the implementation process of a Polish consulting company whichworks towards small and medium-sized businesses. The key success factors will be studied inthe implementation of ERP-systems, and the instance factors of the interrelationship betweenthe consultant and client from a consultant perspective. The review of the literature has beenidentified and discussed in relevance to the empirical study.

Föryngring av skog är en nödvändig, men kostsam åtgärd och därför är det eftersträvansvärt att hitta en föryngringsmetod som är både kostnadseffektiv och ger en bra föryngring. Ett sätt att få en billigare föryngringsåtgärd är att använda frösådd. Vid en lyckad sådd gör det stora plantuppslaget att plantorna får bra förutsättningar för god kvalitet. Dessa plantor får dessutom bättre rotutveckling och stabilitet än planterade plantor. Användningen av skogssådd är dock begränsad av bl.a.
