In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Background: IT-security is included in the concept of information security, which considers all the security of handling information within an organisation. Good IT-security is about finding the right level of measurement, however, it is hard to implemement new IT-solutions in an organisation, particularly within the health care field, where sensitive information are handled daily. Lately the Swedish government, together with county- and city council, understand the importance of IT and health care. Carelink, an organisation of interest, is working actively for the presumption of benefit by using IT within the health care field. During spring 2006 the Swedish government introduced a national IT-strategy.

Hemmasittare is a new term for children and youths with a history of long term truancy. As the term indicates these youths spend most of their time in their homes. This often results in them being socially alienated and the loss of their earlier social network. The consequences of hemmasittande and social alienation are many and include not only a deficient social network but also psychological and physical problems. Research has shown that many of these problems follow on through into adult life.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

This master thesis was performed at Scania Research & Development. The given mission was to see where the department Systems Development should focus to improve their development work. Thus the purpose was to map the product development processes in which the department works today and within them identify improvements. To fulfil the purpose a theoretical study of relevant terms, such as improvement work, product development and processes, initially was formed. The mapping method used is called "walk trough" and meant to let the people working in the processes be guides in their own process.

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

En spelteoretisk analys av lönesystemen i försäljningsföretag och marknadsundersökningsföretag.

Sammanfattning: Detta självständiga arbete har utifrån ett taktiskt perspektiv studerat på vilket sätt obemannade system i kategorin UAS, Unmanned Aircraft Systems, kan tänkas bidra till taktisk uppgiftslösning inom marinen om dessa infördes idag. Arbetet har genom kvalitativ litteraturanalys studerat utvecklingen av dessa system och vad som är rimligt att förmågemässigt förvänta sig av dem idag. En analys har gjorts av den för arbetet aktuella operationsmiljön, den kvalificerade sjöstriden. Vidare har en analys av hur utvecklingen av UAS i USA och Ryssland gjorts för att sätta ett svenskt system i en kontext. Arbetet har haft sin grund i teorin om sjökrigets principer då dessa ger en god teoretisk grund för hur sjöofficeraren bör agera.Slutsatser som redovisas i arbetet är att UAS kan komma att spela en stor roll i att ge ökad förmåga till god lägesuppfattning för marinens taktiska chefer.

Syftet med denna uppsats är att undersöka hur en grundskola arbetar för att implementera studie- och yrkesvägledning i vid bemärkelse, som hela skolans ansvar. Styrdokument beskriver att skolor bör arbeta med studie- och yrkesvägledning på ett långsiktigt och individanpassat sätt för att ge elever möjlighet att göra väl underbyggda val i framtiden. Ändå visar olika granskningar att utbudet av studie- och yrkesvägledning i grundskolan många gånger är bristande och av varierad kvalitet. En grundskola i Skåne arbetar i nuläget för att implementera studie- och yrkesvägledning under lektionstid, som ett projekt i skolorganisationen. Projektets implementering ska leda till att skolans elever ska få verktyg för framtida val men även att skolan aktivt ska arbeta med studie- och yrkesvägledning som ett gemensamt ansvar. Undersökningen genomfördes med en kvalitativ metod där intervjuer gjordes med fem lärare och en studie- och yrkesvägledare alla verksamma inom den undersökta skolorganisationen.

The study aims to investigate the impact of industrialised homebuilding in the creation of the aestheticproperties of the dwelling architecture.The concepts of industrialised homebuilding and the aesthetic properties of the dwelling architecture aredefined by previously developed models. In these models, industrialised homebuilding is described byeight characteristic areas. The aesthetic properties of the dwelling architecture are described by sevenaesthetic qualities.The study was conducted as a qualitative study, and in-depth interviews were conducted. The companyJM AB is the analysed unit that the author of this report has chosen to study. JM employees and by JMhiredarchitects were interviewed.The report concludes that characteristic area planning and control of processes are considered to havepositive impact on the aesthetic qualities if the process is designed in such a way that the creations ofthese are admitted.

Stridsfordon 90 är ett militärfordon som BAE Systems Hägglunds i Örnsköldsvik har utvecklat och startades att produceras år 1993. Fordonet vidareutvecklas och tillverkas än idag och på grund av ökade krav på skydd och eldkraft har fordonets tjänstevikt ökat kraftigt. Från den första versionen av fordonet, Mark 1 (ca 23 ton) till senaste versionen Mark 3 (ca 35 ton). Den ökade vikten påverkar en rad av olika komponenter i fordonet och dess prestanda men det är framförallt drivlina och fjädringssystem som påverkas mest. Fordonet har i sin drivlina slutväxlar som växlar ned rotationshastigheten från motorns transmission och överför på så vis ett ökat drivmoment ut till drivhjul och band.
