Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation
The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas
digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards
to relevant system parameters. The purpose was to evaluate if the technology is a possible solution
to reduce deforestation and support Malawi in climate change mitigation and adaptation.
The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine
which one was best suited to utilise as a digester substrate. After the installation, measurements of
temperature, pH, biogas production, biogas composition and system functionality were made.
The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.
Möjlig efterträdare till skolflygplan SK 60
The SK 60 Aircraft has been a workhorse for the Air Force?s training of future pilots since the late 1960s. The aging SK60 aircraft is going out of style, and the system has merely a few years of total running time left. A replacement for the SK 60 needs to be implemented in the coming years, and the Armes Forces Flying School has been commissioned to conduct flight tests on suitable replacement systems. This study will conduct a system analysis of two aircrafts mentioned in the Flying Schools report.

The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.
Arbetsplatsmobbning : - Är inte att kleta senap på någons brallor!
The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.
Konsekvensutredning inför införande av koncerngemensam systemplattform : Vad skulle det innebär att införa SAP på KSU, Kärnkraftssäkerhet och Utbildning AB
The implementation of large IT-systems is a complex area where many aspects have to be taken into account.KSU, Kärnkraftssäkerhet och Utbildning AB, is a small company in the Vattenfall group that is increasingly being urged to implement SAP, one of the largest ERP-systems on the market. Vattenfalls purpose with SAP is to centralize certain processes within economy that are common to all the companies in the group, this to gain benefits with economics of scale. However, KSU is not convinced that SAP is a suitable system and that the common processes apply to them.The purpose of this degree project is to investigate if SAP is a suitable system and if KSU will benefit from a transition to SAP. Three perspectives were applied to further specify important areas of the main question. From a technical point of view KSU:s demands on a system was mapped against SAP.
Selektion av äpplefröplantor på Balsgård :
Today in Sweden, apples are mostly cultivated for direct consumption, i.e. dessert apples. Apple breeding aims at developing cultivars with new and improved qualities in order to meet the demands of different target groups and to increase the interest in apples on the market. Different target groups have different views on the qualities of an apple. The consumer, for instance, wants an apple that is tasty and beautiful, while the grower, in addition, wants an apple cultivar that is healthy, has good winter hardiness and a predictable, annual productivity.

Testdriven utveckling för mobila applikationer/Android
Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood
Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the
biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last
50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
