Lågenergihus : Att bygga energisnålt
A large proportion of the energy consumption is in the building industry and a large part goes to heating our homes and premises. In the developing countries' development now threatens the large consumption of energy in our earth's climate. It is in the West world that we must be good role models in terms of energy efficiency. One solution to reduce energy consumption for heating of buildings may be to continue to build low energy houses and passive houses, but it is also about rebuilding the buildings that currently have high energy consumption such as the old Million program Houses. These buildings will be standing many years and their energy consumption will not diminish over time by itself and energy prices will certainly not diminish in the future.
Folkbibliotek i skärningspunkten: Gammalt möter nytt i Idea Stores i London.
The aim of this master thesis is to study how the development of a public library by means of ideas and methods from the private sector can be related to traditional core values. We base our study on institutional theory, which focuses on norms and values in an organisation, and new institutional theory, which focuses on how organisations are influenced by changes in the environment. We also use New Public Management with a market focus to analyze the implications of a development towards a more market oriented view.The method used is that of a case study of a new library concept, Idea Stores in London. Idea Stores are a number of new public libraries in Tower Hamlets developed from the results of a major opinion survey about libraries. The Idea Stores combine traditional library services with elements of adult education and lifelong learning in a partnership with local learning centres.
Lilaköttig taggsvamp, Sárcodon fuligíneovioláceus : miljökrav i Sverige och en analys av vad som styr artens etablering
Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered
mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It
form mycorrhiza with pine and dependent on limestone, which makes it connected to
a rare environment. It has therefore been important to study the ecology of it further
and to recognise the requirement it has on the environment more accurate and what it
need to establish in a new area. In this study, 31 of 34 known sites in Sweden was
visited and studied in field and their history analysed through aerial photographs.

The study begins with an evaluation of the Taif Agreement. After acknowledging its effect on Lebanon?s consociational system the function and operation of Lijphart?s four consociational elements are analyzed.
Gymnasieelevers syn på vuxna i skolan i allmänhet och skolkuratorer i synnerhet
The purpose of this study was to examine how Swedish high school students view school staff members, in general, but in particular school counselors. The research questions focused on getting the students descriptions of the staff members roles and functions within the school. The study was conducted using focus group interviews. The answers were divided into themes and then analyzed using role theory and previous research. The results showed that the students relationships with family, friends and previous knowledge about the staff members in school, affects their willingness to seek the support of school staff members.
Riskbedömning av miljö- och hälsoeffekter efter järnhanteringen i Strömsbergs bruk
Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the contaminated sites. This builds on the ?Method for Inventories of Contaminated Sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.

Näsnarens framtid i ett näringsstatusperspektiv
Eutrophication has been a problem in aquatic systems for a long time. It is well known that the key nutrient to control the eutrophication process is phosphorus. Lately, it has been possible to reverse the process and recover lakes from eutrophication.During a long time Lake Näsnaren in Katrineholms kommun, Södermanland, has been exposed of a large amount of phosphorus from the city's wastewater. The lake has a great value as a habitat of rare species but also a high recreation value for people living in Katrineholm and Södermanland. Lake Näsnaren is situated in a Natura 2000 area.
Teknologi och spel i geografiundervisningen : Pedagogiska verktyg eller enbart lek?
Ordet spel och dess betydelse är svårt att beskriva. Spel har många definitioner och studien kommer därför att använda ordet spel för att beskriva applikationer, datorspel, hemsidor och geografiska verktyg. Jag är uppmärksammad på att det finns stora skillnader mellan datorspel och exempelvis Google Earth och har inte som avsikt att klassificera dessa som samma. Dock kommer samtliga att beskrivas som spel eller teknologi, främst för att det underlättar läsningen. Idag använder allt fler personer dator och Internet.
Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Tankar kring scatsång och röstimprovisation - en studie av erfarna jazzsångares uppfattningar om scatsång och röstimprovisation
Scatsång och röstimprovisation är speciella kännetecken som skiljer jazzsång från andra sångstilar. Men det betyder inte att alla jazzsångare gillar att sjunga scatsång eller göra ordlösa improvisationer med sin röst. Vilka tankar finns hos jazzsångare om scatsång och röstimprovisation? Det är en fråga som har inspirerat mig till att göra denna studie. Syftet med denna studie är alltså att undersöka hur scatsången och röstimprovisation uppfattas av erfarna jazzsångare idag.
?Let Love Rule? Kärleken som högsta norm, en möjlighet eller naivt önsketänkande? : En studie om kärlekens funktion hos Margaret Farley och Timothy P.Jackson.
Det ha?r a?r en studie med utga?ngspunkt i journalisten och musikern Kristian Gidlunds sja?lvbiografiska bloggbera?ttelse i kroppen min, som han skrev sedan han blev sjuk i cancer i mars 2011 tills dess att han dog i september 2013, strax innan sin 30-a?rs dag. Bloggen hade omkring 1,5 miljoner la?sare i oktober 2012 och gavs ut i bokform med titeln I kroppen min: resan mot livets slut och alltings bo?rjan under va?ren 2013.Studien ansluter till ett Netnografiskt fa?lt som syftar till att underso?ka social samvaro pa? internet, da? jag underso?ker bloggen i kroppen min som ba?rare av en samtida, meningsskapande funktion. Utifra?n ett fenomenologiskt perspektiv och ett Foucaultinspirerat perspektiv om makt och tystnad underso?ker jag bloggen som en erfarenhetsva?rld mellan en subjektiv och objektiv livsva?rld, da?r subjektet fa?r utrymme att kontrollera sin livsbera?ttelse (sitt livsslut) i relation till en upplevd samtid..
Virtuella Communities : Sociala faktorer i digitala miljöer
Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?.
