In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.

This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.

Global climate change is one of the greatest challenges in our history. As the average temperature is rising due to anthropogenic emissions, impacts such as floods, droughts and hurricanes, affect the lives of millions of people. Though the least developed countries are least responsible for emissions, they are the worst affected. This thesis focuses on environmental justice in the adaptation discourse. By outlining the adaptation discourse from the United Framework Convention on Climate Change principles, to the Marrakesh Accords, via the Kyotoprotocol my ambition is to analyse how environmental justice has been interpreted in relation to the adaptation discourse.

The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.

Not much is today known about how epiphytic lichens are effected by fire. A considerable part of the fires in Sweden today are prescribed fires for the purpose of environmental conservation. How these fires affect lichens is largely unknown. The aim of this study is to find out how epiphytic fruticose and foliose lichens on Scots pine are affected by fire, and to elucidate the relationship between fire intensity and the survival of lichens and later re-colonization. The study was performed at three locations just outside Umeå in Västerbotten that were burned 5-7 years earlier. In all locations there were larger groups of surviving Scots pines with varying amount of fire-damage in the crown, which enabled a reconstruction of fire intensity.

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

This study investigates the concept of regionalism in the context of the Swedish middle-level political arena. The used method is qualitative theory and two cases are studied: Västra Götaland and Norrbottens läns landsting.The aim of the study is to see what the politicans think about Swedens regionalization process by compare the views of politicans that function in a region and in a county council. Do they have the same vision about what constitutes a region and which advantages do they see in working in a region or in a county council? Also dimensions about territorially and sectorial autonomy on the regional level, presented by King and Pierre are investigated in order to explain the different regionala organs functioning accordingly to these dimensions.The empirical material that have been analyzed is taken from 17 interviews, from government writings and reports from the SKL association, Sveriges Kommuner och Landsting, about the topic of regionalization and the effects and goals in Sweden.The conclusion of the material is that there is common opinion among the politicans about the goals of a region and also about which areas that can benefit the most from the perspective of beeing a region instead of a county council. When it comes to explaining the dimensions of territorially and sectorial autonomy the results have shown that the region has the most both territorially and sectorial autonomy, which is due to the regions rightfullness to taxation right, which is high in the region and ensured by a strong catchment area.

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

A sample of milk inoculated with S. aureus was treated with penicillin, and Antipen (a new commercial product containing penicillinase) was added. To another sample with S. aureus and penicillin, formic acid to pH 5 was added, and to yet another sample, a combination of formic acid and Antipen was added. Controls with no penicillin were treated in the same way.

Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

Swedish doctrines emphasises the use of maneuver warfare in combat. Therefore we need tounderstand how a modern state can transform maneuver theories in doctrine into combat practice.United States Marine Corps, a joint armed force in itself, has participated in both Desert Stormand Iraqi Freedom and has since the 1980?s used a maneuver warfare concept. The aim of thisessay is to describe and explain to what degree USMC has conducted maneuver warfare in theIraq wars 1991 and 2003 according to maneuver theory, in the light of how maneuver warfareis thought to be conducted in accordance with then present warfighting doctrines. Theconclusions are that USMC has followed their doctrines in part; the Desert Storm warfaredeviated more from doctrine than the Iraqi Freedom warfare regarding maneuver warfare.

Bakgrund: Behov av dialysbehandling är en omvälvande förändring av patientens livsvärld. Behandlingen är livsuppehållande fram till dess att eventuell möjlighet till njurtransplantation ges. Trötthet samt viktuppgång mellan dialysbehandlingarna, orsakad av minskad filtration i njurarna har i tidigare studier framställts som försämrad livskvalitet vid dialysberoende. Hur beroendet av behandling påverkar det dagliga livet är dock personligt och varierande.Syfte: Syftet med studien var att beskriva hur patienter upplevde att vara beroende av dialysbehandling.Metod: Intervjuer gjordes med nio informanter som lever med behov av dialysbehandling.  Intervjumaterialet analyserades därefter med kvalitativ innehållsanalys, enligt Graneheim och Lundman.Resultat: Trots undervisning före dialysstart om vad beroendet kan komma att innebära, beskrevs beskedet som chockartat när de förstod att dialysberoendet var livslångt. Tidsåtgången för behandling minskade möjligheterna att arbeta.
