Utvärdering av befintliga passivhus : En byggnadsfysikalisk bedömning och mätningar om temperatur, och fukt analys på ytterväggarna
Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project. These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.
Konstruktion av värmespridare med grafit för flygelektronik
This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.
Betydelsen av gränssättning i relationer mellan föräldrar och ungdomar
The purpose with this study was to show the relations between parents and youths from an adult perspective. We wanted to examine in what way the individualized society, limits and psychic health and unhealthy with parents could affect their youths. We chose to make a qualitative inquiry about this subject and had implemented interviews with social welfare secretaries, recreation leader and night walkers. To receive a deeper insight participant observation with night walkers, participant in parent education and participant in three different recreation centres was carried out.Both writers were interested in relations and relations making between people, which led us in to the chose subject. We did not found any earlier research in the subject which made the investigation even more interesting.
Cleaning process of abattoir wastewater with focus on bacterial pathogens
This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch
reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way.
The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was
analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.
Bedömningsarbete i grundskolans tidigare år?lärandesyn, bedömningsprinciper och lärarpraxis : En jämförande studie mellan Sverige och Ryssland
Issues related to knowledge assessment and its consequences for both the individual and the entire school system are topical in today's school debate. The mere fact that didactic issues that focus on assessment are discussed actively not only in scholastic environments but even in media and other communities is further proof that knowledge assessment is an important and complex phenomenon in our lives.The subject that I have chosen to look into is about how the work with assessment issues is handled in Swedish as well as Russian elementary school's early years. The goal with this study is to see how my studies have been conducted with a qualitative approach by which I collected qualitative information in the form of documents, papers and interviews. To make the approach even more appropriate for my area of research, I have chosen to merge two qualitative research methods. The first is a qualitative content analysis which analyses the governing documents.
Flerkanalspublicering : En kvalitativ undersökning av NTs arbete med att publicera nyheter i flera kanaler.
Title: Multi channel publishing: a qualitative study on how Norrköpings Tidningen publishes news in multiple channelsAuthor: Roland AlbinssonThesis supervisor: Per-Anders ForstorpBackground: In this day and age, the media is omnipresent and a part of our daily life. The phenomenon of media convergence can be traced back to the birth of the internet, and today all of the major newspapers have a website of their own. As a result of multichannel publishing, consumers have a wide range of tv channels to choose from, but there is still uncertainty as to whether more channels automatically equates to more and better news. There is no doubt about the fact that multi channel publishing is a necessary survival skill for media conglomerates today, but effects such as news recycling and the concentration of ownership are in conflict with the consumers? availability demands.Purpose: The purpose of this thesis is to, by means of a case study, describe how NT?s multi channel publishing is an expression of media convergence, as well as to study how the news are affected by multi channel publishing.Research procedure: This study is based on three different research methods, observations, text analyses and qualitative interviews.
The Relationship between Internationalization and Firm Performance
Title: The Relationship between Internationalization and Firm Performance Seminar date: 5 June, 2008 Course: Masters thesis in Business Administration, Programme for Managing People, Knowledge and Change, 15 University Credit Points (15 ECTS). Authors: Cheng Hsun Chiang and Márton Pap Advisor: Dan Kärreman Key words: Internationalization, Performance, Multinationality, Degree of Internationalization (DOI), Country of Origin Purpose: To illuminate various crucial aspects of internationalization by systematically contrasting the different models of the multinationality-performance relationship and searching for underlying reasons. Methodology: Meta-analysis on previous theoretical and empirical research. Our emphasis in this paper has been put on the qualitative aspects of the previous research unlike many other conventional meta-analyses that focus on the comparison of the empirical data. Theoretical perspectives: Five main models have been developed by earlier studies to describe the relationship between internationalization and performance: positive linear, no or ambiguous relation, inverted U-shaped, standard U-shaped and S-shaped curve.
Bestämning av dagvattenflöden i Knivstaåns avrinningsområde
The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.
Injuries associated with climbing: a questionnaire study
Background: During the last decade climbing has become more popular and the numbers of climbers in Sweden have increased considerably. Most common are overuse injuries caused by the great stress and strain climbing creates on different parts of the body. Previous studies show that 75-90% of climbing injuries are localised in the upper extremity. Injuries affecting the lower extremity occur often acute and traumatic. Based on these facts and that the number of climbers constantly grows, it is more likely that the need of care from physiotherapist among climbers will increase.
Variation in frequency of alleles in the MTNR1A gene with possible impact on ability of ewes to show oestrus out of season
In Swedish sheep industry it is desired to have lambs slaughtered evenly distributed over the year. Swedish sheep are generally seasonal breeders with lambs born in the spring and slaughtered in the autumn. Some of the breeds, e.g. Swedish Finewool and Roslag sheep breeds have shown ability to lamb out of season. For increased knowledge on the possibilities to breed for out-of-season lambing in Swedish sheep breeds, the aim of this master thesis is to study the variation in frequency of two alleles in the MTNR1A gene in the three breeds; Gotland, Swedish Finewool, and Roslag sheep.
I tid och rum : en upplevelseanalys av Kärnan
In 2005 Gunhild Eriksdotter published Behind The Facades in which she analyses the ways of approaching historical buildings in archaeology. Eriksdotter emphasizes that the archaeology of buildings is in dire need of renewal videlicet the traditional outlook on buildings as two-dimensional objects need to change. She develops a method of analysing the spatial dimensions in a three-dimensional world. By fusing theories and methods in excavating archaeology and architecture, she is able to give us a new way of approaching buildings. Her method includes the analysing of a buildings material, spatiality and use.
Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn
This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.

Vilken kommunikation smörjer börsmaskineriet: En kvalitativ studie av börsanalytikers syn på informationsinsamling och trovärdighet
Stock analysts have through the analyses they write a large impact on the expectations on the market and the direction of investors investments. This creates undesired fluctuations on the market that raises the level of uncertainty. The way that the analysts satisfy their need for information is connected to how their final analysis will be shaped. There is a large knowledge gap concerning the way that the analysts work and this gives unsatisfactory ways of communication. This thesis is set out to create a greater understanding of how optimal communication towards this target group should be brought out.
"Det finns en ram, men inom ramen är det ganska fritt" : En kvalitativ studie om genrepedagogik
The purpose with my essay was to investigate how genre pedagogy works in a practical manor? I wanted to reach a deeper understanding for the genre pedagogy and to find out if it fits all students. To investigate this issue I have asked following questions:What is genre pedagogy?How do teachers work with different genres in the genre pedagogy?For whom is the genre pedagogy?Is the critic right that Frøydis Hertzberg is proposing about the genre pedagogy formalism? I have been using qualitative methods, to gather my empirical data. I have been using two unstructured interviews and one unsystematically observation, in a third grade class in a school south of Stockholm, with 30% second language students.
