Uppvärmning och miljöpåverkan : -en jämförelse mellan fjärrvärme och bergvärme i villa
Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..
Effektiv sökning med Google: en jämförelse i återvinningseffektivitet mellan enkel och avancerad sökning
The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.
Tecknade serier i bokhyllan: En studie i hantering och förvaring av tecknade serier på svenska folkbibliotek.
This thesis investigates the situation for comics in Swedish public libraries. The main questions is separated into two groups, the first dealing with the physical situation were we investigate placement, cataloguing and shelf arrangement. The second deals with the librarians attitudes towards comics and how they may affect their work. The base for this thesis is the idea that the comic medium may sometimes be treated different than the rest of the libraries collections. Because of this, a theoretical basis is developed which focus on different views on comics.
Svårigheter vid färgundersökning av arkitekturbundet måleri Fallstudie: Färgundersökning av en lågerhuggen gördellist i södra valvet på Stockholms slott
This bachelor thesis discusses various difficulties with architectural paint research. The difficulties are exemplified through a case study ? a paint research on a furrowed string-course in the southern vault of the Royal Palace of Stockholm, which was carried out November ? March 2009-2010 on behalf of Statens Fastighetsverk. The paint research was made in order to receive information about the string-course and to get inspiration for a renewed color scheme on it. The base material of the string-course is Gotlandic sandstone and the surface of it is furrowed.
Är vi lika dem? : en kraniestudie av hominider ur ett evolutionistiskt perspektiv
By examine plastic craniums from eight different hominids I wanted to find morfological characteristics that agreed with those of modern humans. The species that were selected had a plastic casting of its cranium in the laboratory at Gotland University. My focus was on species from the family Australopithecius and Homo and only working with their craniums. And this because the cranium and the theeth shows the most visible morfological characteristics between the different hominids. I also wanted,in a small part of the essay, to write about the differences in now living primates and humans skulls.Except from analysing the plastic castings I also studied surveys written by other scientist on the same subject.
Vad sägs om en förändring? ? En diskursanalys av hur privatisering av bibliotek framställs i Biblioteksbladet
The subject of this master thesis concerns the area of change in libraries, with special orientation towards privatisation. Its aim is to investigate how privatisation is portrayed in one of Sweden?s largest library magazines, Biblioteksbladet, in order to gain insight into why these portrayals are what they are, and what consequences they might get. Three theoretical viewpoints create the general base of the thesis; first, Fairclough?s critical discourse analysis (CDA) theory on the relations between text and society; second, Audunsson?s theory concerning how change is dealt with in public libraries; and third, a conceptual framework on privatisation consisting of definitions and perspectives of the phenomenon.
Obstruktiv FLUTD - ett nödvändigt ont eller möjligt att förebygga?
FLUTD - Feline Lower Urinary Tract Disease ? is a complex disease and a common sight in the veterinary setting. Although FLUTD excluding urethral obstruction may be discomforting for the cat and its owner due to symptoms such as periuria, stranguria, hematuria, dysuria and pollakiuria, obstruction presents an acute and potentially lethal form of the disease as a result of uremia and disturbances in fluids, electrolytes and acid-base balances.
A study of literature has been performed to investigate the causes of FLUTD with urethral obstruction and the actions available to the owner to avert them. Potential causes of obstructive and non-obstructive FLUTD have been found to include infections, uroliths, urethral plugs, neoplasia, anatomic abnormalities, trauma, neurogenic or iatrogenic causes. Most commonly a cause cannot be identified and the terms idiopathic FLUTD or feline idiopathic cystitis are used.
As the mortality rate due to urethral obstruction likely is somewhere around 5.8-8.9% and FLUTD including and excluding urethral obstruction constitute great inconveniences, precautionary measures are warranted.
Investeringar i privat och kommunal verksamhet : En studie om faktorer som påverkar investeringar
The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.
Stadskyrkogårdar : socialt hållbar stadsutveckling
This master thesis is a study of how city cemeteries can be used and contributes to a socially sustainable urban development. Today sustainable development and sustainable urban development is something that more or less every organization is working with. Therefore it is also relevant to integrate our cemeteries in this work so that they can become a part of the sustainable urban development process.The thesis gives a basic understanding of sustainability as a concept and also defines socially sustainable (urban) development. The work then immerse itself in various types of park structures and how the relationship between the human individual and the public space work, to satisfy the needs that different people have.The literature study that has been made is also the base for the design of the walking interview that has been made for the two city cemeteries. The cemeteries that where studied where the Assistens cemetery in Copenhagen and the Eastern cemetery in Gothenburg.
Demokrati i förändring : En studie om hur synen på demokrati har förändrats i samhällskunskapsläroböcker över tid
AbstractIn the paper, democracy's development and change are studied in Swedish textbooks related to social science. The study?s starting point is that the picture of democracy provided to students has changed over time. The study aims to see how the view on democracy has altered in Swedish textbooks in social science. In order to examine this, I have studied seven textbooks, from 1945 to 2006, in social science.
Så höjer du sannolikheten för återbesök till din webbplats
The music distribution in Sweden and the world is rapidly changing. The music industry, however, has been reluctant to change the way they distribute music. The consequence has been that illegal music files have been available for downloading to anyone with an Internet connection. Because of the illegal downloading a new law have been implemented in an attempt to stop this behaviour. Our theory is that in implementing the IPRED-law, the sites that were hosting most of the illegal material will experience a severe decrease in traffic.
"Information-as-thing": Förhållandet mellan biblioteks- & informationsvetenskapen och materialbibliografin
The relation between LIS and physical bibliography is examined primarily through an analysis of such LIS literature as applies physical bibliography in research or otherwise discusses its relevance to information studies. Quite a number of scholars are stressing the usefulness of this bibliographical tradition, even though its position in LIS agenda as a whole seems to be less established. These scholars suggest that physical bibliography presents interesting conceptual and theoretical implications for many of the central objects of study in LIS, for example, knowledge organization, information retrieval, and information seeking. It is also suggested that physical bibliography could help deepen our knowledge and understanding of the digital media ecology. Physical bibliography is foremost seen as a method for the analysis of documents, a method in which not least its terminological apparatus may be a significant tool.
Terms and conditions (villkor för orderläggning) : En fallstudie på Ericsson AB i Gävle
This final thesis was performed at Ericsson in Gävle between April and June of 2008. Ericsson is a world leading manufacturer of radio base stations (RBS), which handles mobile phone traffic with 2G and 3G technology. The main purpose of this study is to examine if two different types of products (RBS and site material) should have different terms and conditions, today the terms and conditions are the same for both types. During the course of our study we have tried to think of the terms reliability, validity and generalization. The intention in doing that was to keep the thesis at a high academic level. To name an example of this we have tried to keep our minds at an objective level during the interviews and informal conversations.
Mötet med lärare : - En studie om elevers upplevelser av lärares påverkan av självkänsla och självförtroende
This study is about how students view the effects teachers have on their self-esteem and self-confidence. The theoretical background covers the consequences of success and failures, and the interaction between students and teachers, in regards of self-esteem and self-confidence. The purpose of the study was to examine what had in-fluenced the students? self-esteem and self-confidence in the interaction with teachers. To reach the goal of the study, several qualitative interviews were made with the following questions as base:? Which factors does the student consider to be of importance for their self-esteem and self-confidence in the interaction with teachers?? How does the student feel that these factors were affected concerning their self-esteem and self-confidence?During the analysis and systematization of the transcribed interviews, five factors emerged that effects self-esteem and self-confidence.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
