This study is an initial attempt to investigate the relationship between banks and developers in Stockholm and its regions. It gives a good impression about the field of construction and project developments in terms of the finance and the negotiations associated with these types of projects. Main actors of the Stockholm?s construction financing market were of major interest for this study. On this regard, the relationships and ramifications of this group were investigated by using a qualitative and quantitative research method.

I Sverige och stora delar av Europa har det planterats gran, Picea abies, på marker som tidigare varit lövdominerade. Idag restaureras ädellövskog på dessa marker i ökad omfattning, bland annat för att gynna skogens biologiska mångfald och rekreationsvärden. Syftet med detta arbete var att undersöka överlevnad och tillväxt av ek, Quercus robur, och bok, Fagus sylvatica, som planterats efter gran i Söderåsens nationalpark och i Raslångens ekopark i södra Sverige. I Söderåsens nationalpark undersöktes plantutvecklingen tio år efter plantering på öppna hyggen (ek och bok) eller under björkskärm (bok). För Raslångens ekopark var syftet att undersöka om inversmarkberedning och hägn påverkar initial etablering och överlevnad hos bokplantor på öppna hyggen. Resultaten från Söderåsen visar att ek och bok tio år efter plantering kan nå en hög överlevnad och god tillväxt med hjälp av fungerande hägn och regelbundna röjningar.

The contribution of biofuels to the total consumption of energy in Sweden must increase to 49 % in order to meet the goals for the year 2020 set by the European Union. In order to do so, improved information systems are needed to support the business processes within delivery scheduling between customers and suppliers.Enterprise Architecture (EA) is a concept to enable the alignment of Business processes and Information Systems. EA is the framework for the architectures of business, information and applications. With a comprehensive view of the architectures, an Information System aligned with the Business processes can be enabled. The first step in the development of an Information System is documenting the business processes.The goal of this study is to clarify a generic sequence of activities performed within the delivery scheduling process and the information needed to perform the activities.Data for the study was collected through qualitative interviews, first through a meeting with the respondent and after that a following telephone interview with in total 5 suppliers and 6 customers of biofuels.

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

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.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

The composing of new standards in the area of machinery safety is a continuous work which aims at writing standards that works as a tool for companies and enables them to control if the fundamental demands of security and health which is prescribed by law are reached. It is optional for the companies to choose if they want to use the standards. This report is written in cooperation with SIS and the study were performed within the technical committee SIS/TK 282. The report aims to investigating if the companies that choose to use standards see any economic advantages due to this work, how these advantages take form and where they originate. The main question formulation is how the profitability among companies that have adjusted their production to machinery safety standards are affected. The study was performed with an initial literature study which aimed at obtaining knowledge and an overview over the subject as well as investigate what former studies had resulted in.

Med tanke på att offentlig upphandling är ett mycket stort område, främst med tanke på dess ekonomiska värde, är det viktigt att det finns en väl fungerande konkurrens. Syftet med uppsatsen är att se hur marknaden för offentlig upphandling påverkas av ett större deltagande av SME-företag, vilka möjligheter finns att påverka konkurrensen och hur upplever SME-företagen upphandlingsprocessen. Vi tog en initial kontakt med Svenskt Näringsliv som gav oss information och hjälpte till med avgränsningarna. Tillvägagångssättet i uppsatsen kan sägas tillhöra en abduktivt tillvägagångssätt. Valet gjordes att använda kvalitativ metod och därmed bestod empirinsamlingen av intervjuer med två personer från kommunen och tre företag som deltar vid offentlig upphandling. Därefter började vi jämföra teori med empiri.

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

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.

The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

SUMMARY This pilot study tried to answer the question however the present animal welfare regulations for horses regarding lying hall area requirements are adequate for horses older than 24 months. The study was carried out at one of the largest stud farms for standard bred horses in Sweden. Mares in late pregnancy with an initial mean age of 10 years was used in a behaviour study. The influence of varying space per animal in a loose-housing system on behaviours like the horses' lying hall use, standing, resting, moving behaviour and threats was studied. The behaviour at three different horse densities ? 18 mares, 13 mares and 8 mares (7.4 m2, 10.3 m2 and 16.7 m2 per mare, respectively) ? was recorded by use of video.

In the 1980?s the moose population in Sweden grew explosively due to big changes in the silviculture with clear cuttings instead of single-tree selection. Clear cuttings brought big areas of young forest and therefore a lot of fodder in one place. Since this change, the discussion about how to manage the moose population has grown into a very big problem. Forest owners think that the population needs to be strongly reduced because of all the damage that is done to the young forest when the moose seeks its food, and the economic losses because of that.

When Norway spruce is planted with large initial spacing and grows on highly productive sites in southern Sweden, a high proportion of the stems gets broad annual rings. The thinning programme carried out at the estate of Trolleholm aims to extract stems with too broad ring width. The 3-4 first thinnings are carried out as thinning from above, where only the thickest trees are removed. The internal distance may not fall below 5-7 meters depending on the number of thinning (short distance in young stands). The aim of this study was to examine the thinning model that is carried out at the estate of Trolleholm. A volume table is calculated to describe the model, and data is collected on temporary plots.
