Undersökningsmetodik för klorerade lösningsmedel i marken
Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.
Trådlös strömning av en ljudsignal till multipla mottagare
I detta examensarbete har det undersökts vilken teknik för trådlös kommunikation som passar bäst att användas då en ljudsignal ska strömmas trådlöst till multipla mottagare. De tekniker som jämfördes var Wi-Fi och Bluetooth. Andra tekniker för trådlös kommunikation, ZigBee, ANT+ och NFC, valdes bort för att deras maximala datahastighet eller räckvidd inte var tillräcklig. 3G och 4G valdes bort för att det krävs en licens för att få använda dessa. Som mottagare skulle i första hand Android- och iOS-mobiltelefoner användas.

Armaturfamilj med LED som ljuskälla
This report describes a project, which was carried out as a final thesis covering 30 ECTS during the final semester of the Master of Science programme Industrial Design. The assignment was issued by Fagerhults Belysning AB in Habo. The assignment was to design a family of products in which LED was to be used as a source of light. The main focus in the initial part of the project was to find a way to design the inside of armature which was suitable for LED technology. An armature, already in the range of products at Fagerhult, with the desired qualities that was to be strived after was the Zintra. The lighting source of the Zintra is a compact fluorescent lamp.
Jämförelse av vertikala krafter mellan hov och underlag vid nedsittning och lättridning i trav hos häst :
Equestrian sports and the interest in horses have existed for hundreds of years. It is only in the last thirty years the technological development have enabled closer studies of equine locomotion. The production of both soft- and hardware that manages to capture and analyze the fast movement of the horse has resulted in a large increase in locomotion research.
Even though the interest in horses and the different disciplines they compete in is great, there is a small understanding in how the rider influences the movement of the horse in different types of training.
There are several studies available where horses moving freely without the influence of a rider have been studied. What happens with locomotion and ground reaction forces when a rider and equipment are added is not well studied.
The objective of this study was to investigate if there are any differences in the ground reaction forces between sitting and rising trot.
The study contained seven horses. Six Grand Prix dressage horses and one dressage horse competing at intermediate level.
Vi hör inte läraren! ? En enkätundersökning i årskurs sex om upplevd ljudmiljö i skolan
Noise in schools can have negative effect on the teaching environment and speech perception. The national Child Environmental Health Surveys (BMHE) conducted in 2003 and 2011 studied how 12-year olds experience their sound environment in school. Results showed that the number of pupils that experience annoyance from noise increased from 2003 to 2011.Aim: The aim of this study was to study how 12-year olds perceive their sound environment in school.Methodology and material: A quantitative questionnaire survey was conducted in the sixth grade at two schools. The questionnaire used included questions from BMHE and self-produced questions. Sixtynine students answered the questionnaire.Results: Over 50 % of the respondents experience annoyance from noise in school several times a week.
Journalistik 2.0 : Om journalistens upplevelse av medborgarnas inverkan på tidningarnas innehåll
Title: Journalism 2.0: About the journalist's perspective on citizen participation and its influenceon the news content.Purpose: The aim with this study was to examine whether, and if so how, professional journalists experience that the production of news has changed as the media development has progressed and the citizens opportunities for active participation in this process has potentially expanded.Research questions:Does professional journalists experience that the opportunities for citizen participation in the news making-process has changed with the spread and accessibility of new media- if so, in what ways?Wheatear professional journalists experience that the relationship between themselves and their news sources has changes with the spread and accessibility of new media?What consequences can an empowerment from citizens have on the production of news and on the professional role of the journalist?Theory: This essay is based on theories about convergence, gatekeeping, agenda building, participatory journalism, news sources and the journalistic profession.Method: The survey is based on ten qualitative interviews with ten professional journalists, eight reporters and two web editors from the newspapers NWT and VF.Results: The results of this survey shows that the citizens? opportunities in influencing the production of news has partly changed. The journalists do not experience that citizen participation affects their professional role. Citizens have always had an impact on the production of news but new technology offers citizens and journalists new channels that facilitate the communication and interaction. The gatekeeping process is protecting the decision-making role of the journalist, which restrains citizen participation.

The Instant Generation : - hur ser ungdomars attityder till fildelning ut?
Abstract:Title: Engelska (Svenska)Number of pages: 40 (47 including appendix)Author: Carl StrandTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Fall 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The purpose of this essay is to analyze how young people, in the ages 18 to 25, relate to the subject of file sharing, and what their attitudes to this phenomenon are. I aim to describe how they use file sharing, their knowledge about it, how their usage have changed due to the new copyright law, what their stands are on the question of resource control and management on the Internet, and what they think of the future of file sharing.Material/Method: The method being used is a qualitative focus group interview model, used to investigate how young people look at the subject of file sharing. The results of the interviews is then applied to a theoretical framework based on thoughts of Denis McQuail, Lawrence Lessig concerning creativity, copyright, resource management and file sharing on the InternetMain Results: My conclusion is that the widespread file sharing habits of young people is not only caused by the temptation of getting free stuff, but of the lack of commercial and legal alternatives. Youths are willing to pay for media if the distribution is superior to the illegal file sharing alternative. They are a generation of young people that has grown up in a society where the tendency in many fields has been to make everything faster and more effective.
Diabetes : En studie om informationsbehov och informationssökning kring sjukdomen
The aim of this study has been to examine how people with the chronic disease diabetes are seek-ing information about their disease. The study also look at the sources, which are mainly used, and the information behavior of the participants in this study. Especially in diabetes health care the idea of empowerment is central, which means that the patients need a lot of information to get know-ledge and become empowered. The study also examine the public library as a resource of health information, and for that purpose an examination of the OPAC catalog in two public libraries has been done, using the word ?diabetes? to illustrate the literature and other medias related to di-abetes.
En inklusiv etik på goda grunder? -Vår livsstil och djurens liv, en filosofisk och teologisk diskussion
The relationship human has to animals are complex and I discuss this from a theological and philosophical perspective in this essay. I ask on what grounds, with what arguments and how one could live with an inclusive ethic. I discuss the philosopher Peter Singer and the theologian Andrew Linzey to see their agreements and differences. Linzey has a mystic influence built into the theological perspective. Swedish activists and authors Pelle Strindlund and Annika Spalde call their way of life the ?Way of love? and show an animal-inclusive ethic built on a Christian mystic ground..
LCC-analys av FTX-system : En jämförelse av centralt- och lägenhetsplacerat
This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.
Farthinder med förhinder : om acceptans
A great amount of todays drivers? are constantly exceeding the speed
limits on the roads. As a consequense of this, a large number of
speed redusing devises, for example speed bumps, has been built
around the country.
As reports in local medias point out, the acceptance for these types
of speed reducing devises, differs and there are many thoughts about
location, construction and effect on the traffic safety.
This paper approaches the complexity of these problems from the
drivers? point of view, based on literature studies and a
questionnaire. The goal is not to argue for or against speed reducing
devises, but to try to find the source of annoyment and how to
proceed further.
Some of the problems turned out to be easy to fix, for example porly
marked speed bumps.

Mäktig eller osynlig : En diskursanalys ur genusperspektiv om hur maskulinitet tolkas och värderas i genusmedvetna texter och i museers utställningar
The survey aims to problematize masculinity in the exhibitions of the museum. In what way is masculinity interpreted and valued in exhibitions? What is the attitude towards masculinity in gender oriented museological texts? This study investigates in which way masculinity is written about ? how interpretations of masculinity emerge in the texts and what consequences this may have.The survey is based on the method of discourse analysis and the material is processed from a gender perspective. The source material consists of museological texts dealing with the topic of gender and museology, which also is the core material. A complement to this is a selection of exhibition catalogs from museums as well as reviews which are also based on art exhibitions. The main point of the source material consists of the museological texts.The survey highlights that the gender-conscious museological discourse understands, interpret and evaluate masculinity on a more or less given regulatory framework.
