Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Strategier för framtida utveckling av fastigheter. Ombyggnation Masthugget 11:13
HSB Göteborg owns and manages the property Masthugget 11:13 also called the Corvette in Gothenburg. The Corvette contains mostly office space but also shops, homes and garages. HSB Göteborg utilizes approximately 5000 square meters to its headquarters but in December 2014 they will move operations to Johanneberg Science Park. The risk of an increased proportion of vacancies in combination with relatively low rents and other tenant terminations allows HSB to ask for a future plan for how the real estate should be developed in order to remain profitable.Through studies of the area, urban office prospects, property current status and legal and economic conditions have different potential types of businesses been evaluated. City Planning Office program proposal forms the basis for the analysis of future plans for the area.
Passivhus det långsiktiga valet. En konkret jämförelse mellan konventionellt byggande och passivhus
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Det mångkulturella biblioteket : En studie av invandrares biblioteksvanor vid Biskopsgårdens bibliotek i Göteborg
In this diploma work we present the results from a study of how adult immigrants utilise the services provided by the public library in Biskopsgården, Gothenburg. A survey encompassing 51 library visitors of foreign origin and an interview with two librarians at the library were performed.The results from the survey show that the majority of the informants were male students inages from 26 to 45 years and that they had been living in Sweden for a maximum of five years. 73% of the informants used the library to borrow literature in Swedish, 53% to read newspapers and periodicals in their native language, 43% to borrow literature in their native language and 43% to read newspapers and periodicals in Swedish.These results were compared with two other related studies with which partial correspondencewas found. In addition, related topics such as multicultural librarianship and the psychological aspects of immigration are discussed..
Grönt med personalen. Det interna värdet av Schenkers miljöarbete
Title Greenlighted employees ? The internal value of Schenker?s environmental work.Author David Fridner.Course Master thesis in Science of Media and Communication.Department of Journalism and Mass Communication, University of Gothenburg.Semester Spring semester 2009.Tutor Professor Monika Djerf-Pierre.Number of pages 55 (appendix 23).Aim The aim is to study the internal value of Schenker?s environmental work.Method Qualitative and quantitative method.Material 20 interviews from four workgroups: managers (4), sales (5), customer-services (4) and truck drivers (7). 148 websurveys from two workgroups: sales (106) and customer-services (42).Main result Schenker is perceived as an environmentally friendly enterprise. Much due to the fact that the company?s impact on nature only has little to do with how the staff evaluate its ?greenness?.
?världens mest fruktade terrororganisation? en diskursanalys av rapporteringen om Islamiska Staten
Title: ?världens mest fruktade terrororganisation? en diskursanalys av rapporteringen om Islamiska Staten Author: Martin Landin Subject: Undergraduate research paper in Journalism studies, Dept. Of Journalism, media and communication (JMG) Gothenburg University Term: Autumn 2014 Supervisor: Gabriella Sandstig, JMG GothenburgPages/words: 34/16295Purpose: The purpose is to examine the discourses that characterize the news about the Islamic state (IS) in Swedish newspapers, and to study how these discourses are expressed. Method: Critical Discourse Analysis Procedure: 10 articles from Dagens Nyheter and Svenska Dagbladet were analysed through Critical Discourse Analysis. Results: The analysed articles shows tendencies of orientalist discourse and of a propagandistic discourse which is a part of war journalism..
Utvärdering av röstträning på logopedprogrammet i Göteborg
The purpose of this study was to examine if there were anychanges in quality in the voices of speech and language pathology studentsafter four years of study at the University of Gothenburg. Recordings oftwenty student voices from the first and eight semesters were evaluatedperceptually by six speech-language pathologists. The parameters judgedwere: vocal fry, glottal attacks, strain, breathiness and resonant voice, usinga scale from 0 to 10. Acoustical measures were made of F0 mean andmedian to detect possible differences between the two recordings. Theresults show a significant decrease in vocal fry, glottal attacks and strain aswell as an increase in resonant voice and a significant decrease in F0 meanand median.

Översättning och utvärdering av det bildbaserade förståelsetestet TACL-3 - en pilotstudie
Test for Auditory Comprehension of Language -3 is an American picturebasedtest developed to examine children?s auditory comprehension of language.The aim of the study was to create a translation and to examine if the test wouldcontribute to the information about a child´s language comprehension received bysimilar tests that are used today. In the present study the test items were translatedinto Swedish. The translation was evaluated with 32 children in three different agegroups at a school in central Gothenburg. A linguistic examination of thetranslation and a list of the grammatical structures that are tested were made.
Miljödiplomering: En jämförande implementeringsstudie av skolor i Norra Hisingens stadsdel
This thesis is a product of research about how implementation issues occur due to the relationbetween bureaucrats and politicians. Our study treats the democratic dilemma that occurs whenschools are to implement environmental certifications. Through a comparative study we comparetwo schools in Norra Hisingen, a district in Gothenburg municipal where one of the schools iscertificated and one is not. By using theories from top down and bottom up approaches toimplementation we develop key factors that will lead us to answer our research questions.Through text analysis of policy documents and through interviews with bureaucrats we analyzewhat may be the causes for only one of the two schools to be certificated though Gothenburgmunicipal wish all schools to be. Through our analytical tool we can establish that the policydocuments are well formed according to our top down-theory and that these documents does nothave a major impact on the fact that one school is certificated and one is not.
