Stubbtransporter - en jämförelse av tre olika transportsystem
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.
Den ekologiskt hållbara staden : en diskursanalytisk studie av styrningspraktiker i Hammarby Sjöstad
This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.
Utveckling av metod för erfarenhetsåterföring vid stadsbyggnadsplanering
The paper is a thesis made by three students in the engineering program at Jönköping School of engineering. The thesis was overseen by the urban planning office and features data from Jönköping County.The purpose of the thesis is to improve future central districts by improvement of work methods. The aim of this thesis is, through an evaluation of process mapping, develop a model for systematical work methods with better experience feedback in the urban planning. The following three questions have been answered:? How is the process mapping of the urban planning in Jönköping County built today and how did it affect the current district Kålgården?? How can the urban planning of Jönköping improve with a more systematical work method with better experience feedback?? How can critics elaborate the developed method to make it enough stable and in general applicable method to enforce on future districts?Literature studies and interviews were made to review the work methods of the office of urban planning as well as how their experience feedback works.
Förslag till vägbro vid Hössnamotet - ? Konceptframtagning och kontrollberäkning av bro över väg 40
Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.
Gnosjöandans barn och deras framtidsvisioner : En studie gjord på Entekprogrammet i Gnosjö
The aim of this thesis is to study and analyze a village in the southern of Sweden called Gnosjö, which is famous for a special spirit of industrial success and entrepreneurship. Gnosjö has been successful and famous for many years but is now standing in front of several threats, like a growing number of out moving inhabitants, a low standard of education and difficulties for women to make carrier. Trying to reduce the threat of young inhabitants moving out, a new education program started three years ago with the purpose to make young students to be more interested in the technical development of the industry and make them stay in the district and hopefully be entrepreneurs.The research questions are; which consequences does ?Entekprogrammet? and the background of the students have on the students view on the spirit of Gnosjö, carrier in the local industries and wish of staying or moving from Gnosjö. Furthermore, I want to see if there are any differences between the girls and the boys, does sex have an influence on the view at the future? The study is made by qualitative and quantitative method.
Från vilja till genomförande - Förändringar i arbetet med våld i nära relationer inom en stadsdelsförvaltning
The aim of the study was to examine prerequisites for the changes that are taking place within working with Intimate Partner Violence in Västra Hisingen (a municipal district in Gothenburg, Sweden). My research questions concerned incentives for the new features, their practical consequences and prerequisites for implementation. The study has been performed by three focus group interviews with different parts of the organization represented. The work material has then been analyzed using Implementation Theory, Human Service Organization Theory and theories on breaking up. The study showed that all respondents were motivated to perform the changes, but also that there were significant differences between the groups? conceptions of what implementation demands, and of the organizational support today.
Vederlagsgrundande mätning med skördare
This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district.
The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.
Att mäta ankeltryck i primärvården : Distriktssköterskors och distriktsläkares uppfattningar om en undersökningsmetod och dess användning
Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.
Undersökning av genuttrycket av homeoboxen HOX A6 vid pyometra samt försök att bygga upp en in vitro-modell för pyometra
This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

Analys av sorptiv kylning i industri- och kontorsbyggnader
Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.
Bostadssektorns koldioxidutsläpp
Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.

Biblioteksutvecklingen i Kolbäck 1913-1954
The purpose of this Master?s thesis is to describe and analyse the development of the public and the study circle libraries in the district of Kolbäck during the period of 1913-1954. The factors important for the library development described in sub-questions are: financing, locality, staffing, stock of books, book-lending level and uniting district effects. I use a hermeneutic interpretation model of interaction between the parts and the wholes, between reasons and results. This research leans mainly upon material which is sent to be deposited in archives in Hallstahammar, Västerås and Grängesberg.
The possible role of transmissible gastroenteritis virus (TGE) and porcine respiratory corona virus (PRCV) in the mortality of Ugandan back-yard piglets
In Uganda, small scale pig production plays a major role for households to earn a living and to secure their access to meat. Piglet mortality due to diar-rhoea-related dieseases is high. In an attempt to understand the underlying causes for this high mortality this study aims to investigate the role of trans-missible gastroenteritis virus (TGEV) and is a part of a larger project con-ducted at Makerere university in Uganda.
A complicating factor in this investigation is the porcine respiratory corona-virus (PRCV), a stabile mutant form of the TGE virus. The occurrence of this virus had shown to alter the impact of TGEV in e.g. Europe and North Amer-ica.
