Värmeledningsförmåga hos betong
This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.
En empirisk studie av biståndets effekt på u-länders ekonomiska utveckling 1975-1999
The aim of this paper is to analyze aid, grouped into sectors, and its effect on growth in developing countries, to find out which type of aid has had the most positive effect on growth. We compiled a regression analysis based on panel data over 81 developing countries from 1975-1999. In our first regression we considered and group countries by institutional quality, in the other we considered and group countries after regional differences. As a measure on institutional quality we used the KKZ-index. The principal aim of this paper was to find out what kind of aid is the most efficient in its influence on growth in LDC?s.
Kontaktfamiljsinsatsen : Unga vuxnas upplevelser av insatsen kontaktfamilj som barn
The purpose of this study was to describe and analyse a group of young adults? childhood experiences of the intervention "contact family". The used methods were qualitative interviews and a standardised formulary with life questions, to strengthen the interviews and to compare data. The theoretical frame was taken from Bronfenbrenner?s child development theory and Antonovsky?s salutogenic perspective, which we supplemented with Hilchen Sommerschild?s theory about the "conditions of control".
Torkklimat under byggproduktion : En kvantitativ studie baserad på klimatdata och litteraturstudier
En utmaning under produktionen är uttorkning av byggfukt i byggnadens betongbjälklag. Om uttorkningen försenas kan golvbeläggningar inte appliceras i rätt tid, men att arbetet forceras är inte ett alternativ, då risken finns att fuktskador uppkommer under driftsskedet. Avgörande för att uttorkningen skall fortskrida enligt plan är att torkklimatet i byggnaden är gynnsamt för uttorkningsprocessen. För att kontrollera torkklimatet genomför företaget ett omfattande arbete genom att mäta klimatet, där dataloggar på olika platser i byggnaden registrerar luftens temperatur och relativa fuktighet. Tillsammans med trendmätningar i betong är tanken att insamlad data skall ge en bild av hur uttorkningen fortskrider.
Demokratiutveckling i svenska kommuner : en komparativ studie ur deltagardemokratisk synvinkel
The main purpose of this paper is to examine and compare the democratic situation and developement in Malung and Nyköping, through a perspective of participatory and deliberative democratic theories. The questions I?ve examined are On what priorities the actions of developing democracy are built? Which positive effects have been reached and what problems have arisen? What are the solutions they have found to the problems? How does one experience the results of the experiments and actions taken? What are the similarities and differences between the two cases? and What is their relationship to the theories mentioned above?The questions are answered through interviews with four central actors in each case and examined in relation to participatory and deliberative democratic theories and in comparison of the two cases.The results have been that even if none of the cases respond to one theoretical ideal, they have touches of both theories as well as representative theory. It shows, however, that in Malung the representative democracy theory is the strongest represented in actions and politics, while in Nyköping the participatory democratic theory is stronger. In short, the most positive and negative effects respond well to the theories..

Optimization of Burner Kiln 7, Cementa Slite
In this report focus is put on the combustion process at a cement plant. Combustion is the
heart of the cement making process and absolutely crucial to have under full control and well
optimized.
The fuel is put into the process through a burner pipe and this burner pipe is modified to
reach a more efficient combustion. The primary target is to enable burning of heterogeneous
alternative fuels and increase the production level. Other positive effects from this type of
optimization is lowered specific fuel consumption and lowered CO2 emissions.
A redundant burner is chosen for the project and overall the project steps are the following:
1. Installing a Jet air nozzle ring in a way so it can move both axially and radially due to
temperature changes.
2.
Attityder till återintroduktion av visent i Sverige
The European bison is a species which is no longer present in the wild fauna of Sweden. Reintroduction has been proposed in several different forums. Reintroduction is an attempt to reestablish a viable population of a species in an area to which it is native. To make such an operation successful in the long run it is essential to know the attitudes of the stakeholders involved. This study has sensed the attitudes towards reintroduction of European bison to Sweden.
De Tre Små Husen
Detta arbete är en studie i hållbar gestaltning, där de många teoretiska principer appliceras på tre mycket olika platser på jorden. Tre ekologiskt hållbara enfamiljshus projekteras i Sibirien, i sydöstra Spanien, och i Stockholms inre skärgård. Husen är helt olika. Vitruvius sade: "Vi måste börja med att beakta de länder och de klimat som hus skall byggas i, för att gestalta byggnaderna rätt. En typ av hus är lämplig för Egypten, en annan för Spanien, och ytterligare en för Rom.

For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.
Mekanisk integration av en IR-detektor i en Stirlingkylare
The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.
Svenska buddhismbilden : En kvalitativ innehållsanalys av buddhism i läroböcker för Religionskunskap 1
Western scholars have long sought to grasp the essence of and explain Buddhism. Western representation of Buddhism has been in a manner that reflects their concerns and interests. In addition to this it is also known that Buddhism in Sweden is seen in a favorable way. This study tries to locate where this positive attitude toward Buddhism stems from and if it is represented in this manner in Swedish textbooks. Therefore three textbooks of upper secondary class of religion are to be examined, not only to see if there is a positive attitude towards it, but to see in what manner Buddhism is depicted in Swedish schools on the whole.
Att måla läppstift på grisen: En fallstudie om den interna interaktionen mellan Inköp och Miljö i arbetet mot hållbar utveckling
During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.
Corporate Social Responsiblility- To What Extent?
In order to investigate the perceived Corporate Social Responsibility (CSR) concept and to indentify what expectations the key stakeholders have on the Pharmaceutical Industry both secondary and primary data has been used. CSR can be perceived as a corporate reputation enhancing tool, however it can also put pressure on corporations to behave as good corporate citizen responsible for thier stakeholders. All stakeholders´ interests therefore have to be consider in order to immprove corporate reputation..
Så använder jag boken : Fyra SO-lärares syn på - och användning av läroboken
AbstractThis degree project focuses on the questions how teachers´ within the four socially oriented subjects? history, geography, religion and social science use the textbook, and their attitudes towards textbooks. The method used in this project was interviews with teachers. Previous research shows that teachers use the textbook to a great extent. Studies also show that teachers? way of educating depends upon their individual educational attitudes.
