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.

Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry

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.

De som slutade gå i skolan : en kvalitativ studie om hemmasittare

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.

RAFFLES CITY - Lokala och globala dimensioner av ett urbant komplex i Chengdu

In a time where many Asian metropolises experience an expansive development new urbanconditions are created and the already existing disappears or being replaced. Asian cities develop ata pace that is unprecedented in our history and which, through a western perspective can seemharsh. By focusing on an urban complex in Chengdu, capital of the southwestern province ofSichuan China, the study asks; is it possible to see this rapid urbanization from another perspective?The study examines the local and global dimensions of Raffels City, and how concepts such asnostalgia and authenticity, related to the city, can be understood in an urbanization that is so markedby massive demolitions. The study shows that these concepts can be expressed in several ways, andthat an awareness of them does not necessarily control the view of the city..

Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems

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.

Duo - ny skola på Hälsingehöjden

A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design.By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings.

Processer för Systems Development : Kartläggning, problemanalys och ? prioritering

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.

Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

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.

Unmanned Aircraft Systems och dess möjliga roll inom Svenska marinen

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.

Studie- och yrkesvägledning som hela skolans ansvar

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.

Posthuset blir hotell En studie av Centralposthuset i Göteborg och dess omvandling

This essay in Art History treats the former Central Post Office in Gothenburg, Sweden, and its recent transformation into a luxury hotel. The magnificent original building in neo-classical style, inaugurated in 1925, has been supplemented by a twelve stories high tower in postmodern style containing hotel rooms and suites, creating a complex architecture. The approach of this essay is that of ?lived architecture?, that is, how people experience and act in relation to the building. It is argued that the history of the building is rewritten in the marketing of the hotel and the management?s concept of creating a comfortable ?mini-world?for its guests.
