Verifiering av beräknad energiprestanda för flerbostadshus byggda år 2007-2009
The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.
Ett Omtvistat Himmelrike : En komparativ historiebruksanalys av Ridley Scotts epos Kingdom of Heaven med utgångspunkt i postkolonial och genusinriktad teoribildning
The following study is a comparative analysis on the usage of history in Ridley Scott?s epic Kingdom of Heaven. Based on the thesis that this movie has a lot to say about contemporary political values, it compares the theatrical version from 2005 with the 45 minute extended Director?s Cut, which came out on DVD in 2006. Firmly based in the popular-cultural context I tried to evaluate whether these changes related in any way, to matters concerning the current gender debate and post-colonial theory.
Framtagning av en rörväxlaretill sopsugsystem
The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.
Jämställt ledarskap? Genus, organisation och ledarskap i skolans värld.
In today´s labour market, men and women are segregated, both vertically and horizontally. Exceptions to the rule of gender segregation are few. There is, however, one managerial group where women and men are equal in numbers: school principals. In a short period of time, the distribution in terms of sex among principals in Sweden has changed dramatically. How does gender equality in numbers affect gender equality in a qualitative sense? That is the focus of this thesis.
?Boken vindlar och underbarar, jag får tänka nya tankar om mig själv och omvärlden?: Hur vuxna reflekterar kring sin lästa skönlitteratur med hjälp av läsdagbok
The aim of this master?s thesis is to investigate how adults describe their individual reading experiences, on the basis of their own reflections by keeping a reading diary. Reading diaries kept during two months and a qualitative questionnaire for each of our nine motivated and advanced adult readers, were analyzed by using qualitative content analysis. The study was carried out on the Internet. The theoretical framework that served as a point of departure is Ross? and Chelton?s model for the process of choosing a book to read for pleasure, Nussbaum?s moral philosophy and thesis ?Reading for life? and Mukar?ovský?s theory of the aesthetic value.
Framtidens Hus
The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

The study is both qualitative and quantitative.
Olika kommuner - olika förutsättningar? : En jämförande studie av två olika kommuners missbrukarvård och dess konsekvenser för klienten
Our main purpose has been to describe and compare two community's ways of organising and executing the social welfare sectors drug and alcohol abuse programs. We also wanted to explain the similarities and differences we found with the help of an organisations theoretical perspective. A second purpose has been to try to find out if the difference affects the clients possibility to receive equal care.To find out how the community's organise and execute their drug and alcohol programs, we interviewed two social workers in leading positions in Landskrona and Ängelholm. We have further more, to find out if the differences we found influencing the clients possibility to recieve equal care, completed an inquiry with fictional cases that all of the involved social workers, at each community, built an opinion upon.Our main result showed more simmularities than differences in our two community's ways of organasing and executing their drug and alcohol programs. We judged the clients possibility to adequate care to be equally sufficient no matter where he sought care, since our study showed that the social workers choice of approach did not differ significantly between the two communities, even though we found differences in their way to organise and execute the social welfare sectors drug and alcohol abuse programs..
Är skolbiblioteket viktigt? En undersökning bland elever, lärare, skolbibliotekarie och skolledning om deras attityder, behov och förbättringsförslag på en utvald 7-9 skola i Bergslagen.
The purpose of this essay is to illustrate the importance of the school library in a selected junior high school. My investigation is based on both theoretical and empirical studies. The aim of the theoretical part is to create a platform and refer to thoughts, roles and laws concerning the activity of the school library. The empirical investigation consists of two parts: questionnaires among students and teachers, plus interviews with students, teachers, headmaster, school librarian and the management of education. Everybody shows a positive attitude towards the school library and considers it important for the students exams.
Att mötas i en vitlökspress - en studie om korpus
My field is Korpus and in this project I am investigating what role that plays for me as an artist connected to craft. To really get close to, and understand Korpus I have deconstructed it to find clues to why the silversmithing field looks like it does and how we got here. I believe Korpus has not yet come out of the closet for what it really can be. That it carries a great heritage of traditions and preconceptions that it would do well to shake off a little bit of. Can Korpus as an art field really survive in Sweden, where the Church has no power and silverware is no longer a need to demonstrate ones economic prosperity at an important dinner party? To help myself get closer to these objects I have given my own definition of Korpus.

To achieve the studys? purposes and to be able to examine professionals? views a qualitative approach is taken with semi-structured interviews. Six professionals who work or have been working in the organisation KAST (Buyers of sexual services, own translation), who are situated in Malmö, Gothenburg and Stockholm, have been interviewed.
Miljöbetong
The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.
Religionslärares didaktiska reflektioner : om livsfrågor och populärkultur i undervisningen
This paper aims to describe how religion teachers in Swedish schools teach concerning questions about life issues and popular culture. To research the teachers' didactic approach to these issues, didactics has been defined with three educational questions: what, how and why. The essay focuses on teachers' effective implementation of teaching on life issues and popular culture, which we used a theory of offering meaningfulness describing what subject matter that may be imparted to the students. An offer of meaningfulness can be pursued and can be made visible in the context of what and how performs the teaching and also in the context where the teacher planned the teaching elements. The method that the paper has used is the interviews of four different active religious educators in Stockholm and Uppsala area.
Kvantfysikens grunder i Gy2011 : En tolkning av kursplaner för fysik 1 och 2
AbstractThe beginning of the 20th century gave birth to quantum physics. Within years it revolutionized material science and converted the theoretical foundations of modern chemistry, and to some extent even biology, to physics? new branch, molecular physics. Merger of relativistic and quantum physics soon led to the development of quantum field theory and a deeper understanding of the elementary constituents of matter. Part of this development found its way into high school textbooks as early as in the 1950s.
Utvärdering av en Magnetic Harmonic Traction Drive
In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.
