Detaljeringsgraden i dagens detaljplaner, en studie av femtio planer för nyexploatering av större bostadsområden

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.

Sverige i fokus? - en kritisk diskursanalys om massmedias nyhetsrapportering av den gemensamma energipolitiken i EU

In Jaunuary 1995 Sweden became part of the European Union. Consequently Sweden agreed upon beeing part of a greater integration project with influences of federalism. However, many argue that the discourse that has been been dominant in Sweden is the discourse where we focus on the national state instead of the EU. In my essay I question whether the discourse about ?nationalstatslogiken? is found in the daily press in Sweden.

Chalmers oanvända datorkraft - Distribuering av arbete och energihantering med HTCondor

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

Matavfall från livsmedelsbutiker : - En analys av den kommunala hanteringen i Sverige samt en detaljstudie av förhållandena i Umeå kommun

Food waste from grocery stores - An analysis of municipal management inSweden and a detailed study of the situation in Umeå municipalityThe objective of this thesis was to analyze the municipal management of food waste fromgrocery stores in Sweden in general and in Umeå municipality in particular. Furthermore theobjective was to account for the different waste treatment methods that can be used and toevaluate them from an environmental perspective. In order to analyze the municipalmanagement a survey was sent to all of the municipalities/municipal waste companies inSweden. A general comparison of treatment methods was carried out on the basis of ascientific review and a system analysis was performed in order to compare three differenttreatment alternatives for the food waste generated in grocery stores in Umeå. The surveyshowed that the legal definition of food waste from grocery stores is unclear and variesbetween municipalities.

Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Den sovjetiska kulturkampen 1917-1932 sedd genom Bresjnevadministrationens lins. En historiografisk studie.

This Masters thesis is a historiographic study, which aim is to investigate how the Brezhnev administration 1964-82 describes the events taking place during the soviet cultural struggle 1917-32. The investigation is limited to how some of the literary groups, organisations and currents as well as a small number of Russian writers are viewed by the administration. The third and last edition of the Great Soviet Encyclopedia, which is considered as equivalent with the soviet official view, is used as source. The analysis made in this thesis is divided in two parts; the text analysis of the writers biographies is compared with the result of a discourse analysis, whose target is some of the literary groups, organisations and currents during the topical period. The discourse analysis is a pre-analysis, but its conclusions also have a value in itself.

Energiövervakning och styrning av snarta hem

Energimätning och övervakning kan bidra till minskad energiförbrukning genom att hjälpa en användare att ta beslut över energianvändandet. Valet av examensarbete gjordes p.g.a. behovet att ge användarna möjlighet att påverka sin energiförbrukning och övervaka sina elprodukter. Ett koncept togs fram där toppvärden på spänning och ström, effektfaktor, spänning-ens vågform, aktiv, reaktiv och skenbar effekt mättes. Samtliga värden skickades till en server som lagrade informationen och innehöll en hem-sida för presentation.

Att främmandegöra det välkända

Our modern swedish society is charactarized by peoples and cultures from all over the world. In this perspective I believe that young pupils of today need culture studies in school in order to understand themselves and further to recieve knowledge about different cultures, traditions and lifestyles. The present study is an attempt to investigate the potential of the ethnological culture analysis as a pedagogical method. The paper is divided into two sections; one in which I (a student teacher in swedish language training) have applied the culture analysis in a literary context. By using the culture analysis on Emily Brontë´s classic book Wuthering Heights I have tried to let typical elements from the Victorian era appear.

Boleko

Changes in the climate and the environment are largely consequences of human influences. Resources are given to teach adults about the environment. However, there are problems in focusing on adults because it is difficult to influence people when they already have created a lifestyle. We have instead chosen to focus on teaching children about changes in the climate and the consequences of this.Many of the toys available on the market today encourage children to consume. Luxury cars and dolls with hundreds of accessories are often made of materials that has have a negative effect on the environment.Another problem we often encountered during the year is the declining interest in technology and science.

Social Return on Investment, SROI, the value added for families before and after using Solvatten in the Bungoma district in Western Kenya

The lack of fresh and clean water today causes severe problems, mostly in developing countries. Waterborne diseases like typhoid, cholera, amoebic dysentery and diarrhea create health problems and deaths among people. There is a need for low cost interventions like household-based water treatment and safe storage (HWTS). Solvatten AB is a Swedish company based in Stockholm. Their product, Solvatten, is a household water treatment unit that can treat water containing viruses, parasites and bacteria.

BIM för Hållbart Byggande

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Productivity of integrated harvesting of pulpwood and energy wood in first commercial thinnings

The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.

Fordonsgas ur gödsel och vall

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.
