VEM HÖR TILL? : Eller inte?
Over the past two decades, trends of integration processes in terms of citizens of different ethnicities, different gender and different sexual belongings, etc. has grown thanks to debates and new legislations. A marginalized and discriminated group in society such as women, immigrants, homosexuals, transsexuals and people with disabilities during this time has gained momentum in the community. The curiosity over whether these developments have changed our attitudes and values to the world around us, and if so how, is the reason for this master's thesis in disability studies.The Swedish development forms the basis for my belief on a younger generation of people who would be more tolerant than previous generations, in terms of what is considered to belong to the norm in our society, or not. The purpose of this study is therefore to increase knowledge about what beliefs young people today have about people with disabilities.
Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos
This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Aktiv bullerdämpning i ventilationssystem
Active headsets have been on the market for years and now it is time for
something else to enter the stage. The technology of active noise reduction can
for exmple also be used in ventilation systems for reducing ventilation noise.
An active control system principally consists of four important components,
namely the downstream error microphone, the upstream detection or reference
microphone, the digital signal processor (DSP) and a loudspeaker.
The upstream reference microphone listen to the primary ventilation noise and
sends it to the DSP which makes a phase shift to the signal and sends it to the
loudspeaker. The loudspeaker sends out the opposite waveform of the incoming
one and reduce the primary ventilation noise.
Elevanpassad undervisning : En studie om gymnasieelevernas perspektiv på lärande i naturvetenskapliga ämnen
The purpose of my study is to determine students? attitudes to the Natural Science subject. I want to contribute to scientific discourse about different learning styles that can respond to childrens? requirements in teaching as well as to determine the student?s experience of learning styles. The studies were carried out at an upper secondary school in Stockholm (spring term 2011) for three different classes.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
Ett sannolikhetsbaserat kvalitetsmått förbättrar klassificeringen av oförväntade sekvenser i in situ sekvensering
In situ sekvensering är en metod som kan användas för att lokalisera differentiellt uttryck av mRNA direkt i vävnadssnitt, vilket kan ge viktiga ledtrådar om många sjukdomstillstånd. Idag förloras många av sekvenserna från in situ sekvensering på grund av det kvalitetsmått man använder för att säkerställa att sekvenser är korrekta. Det finns troligtvis möjlighet att förbättra prestandan av den nuvarande base calling-metoden eftersom att metoden är i ett tidigt utvecklingsskede. Vi har genomfört explorativ dataanalys för att undersöka förekomst av systematiska fel och korrigerat för dessa med hjälp av statistiska metoder. Vi har framförallt undersökt tre metoder för att korrigera för systematiska fel:I) Korrektion av överblödning som sker på grund avöverlappande emissionsspektra mellan fluorescenta prober.II) En sannolikhetsbaserad tolkningav intensitetsdata som resulterar i ett nytt kvalitetsmått och en alternativ klassificerare baseradpå övervakad inlärning.III) En utredning om förekomst av cykelberoende effekter, exempelvisofullständig dehybridisering av fluorescenta prober.Vi föreslår att man gör följande saker:Implementerar och utvärderar det sannolikhetsbaserade kvalitetsmåttetUtvecklar och implementerar den föreslagna klassificerarenGenomför ytterligare experiment för att påvisa eller bestrida förekomst av ofullständigdehybridisering.
Älgexplosionen på 70- och 80-talet, ett hot mot sågverken?
The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber.
The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development.
There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

Identifiering av röjningsbestånd med hjälp av flygburen laserskanning
Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.
Med erfarenheten som utgångspunkt : En studie om den subjektiva erfarenhetens relation till det textdu som framträder i skriftlig sjukdomsinformation
In order to convince, one must know which arguments are most suitable for the specific situation. But even if you think you know how others will react to your arguments, you may be wrong. Therefore, the purpose of this paper is to find out a way of examining to what extent informative text take account to the subjective views of their addressees. The theoretical framework is Blitzer's theory of the rhetorical situation, pragmatic theory of speech acts and their presuppositions, Burk´s theory of consubstantiality and phenomenographic theory of subjective perceptions. Methodologically, phenomenography has also been used as a guideline for selecting informants, collecting data and processing the interviews.
Professionell barnteater på folkbibliotek: ?att bli berörd, att bli glad, att få skratta?
This master?s thesis concerns the performance of professional children?s theatre in public libraries. With qualitative interviews I have looked into how four children?s librarians and two theatre consultants appreciate professional children?s theatre, and furthermore I have looked into their view on the importance of theatre for children. My intentions have also been to investigate their views on the function and status of children?s theatre in public libraries and also the relationship between library and theatre activities for children.
Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran
A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

Processorienterad arkivredovisning : Ny arkivredovisningsmodell tilla?mpad i fem svenska la?rosa?ten
The investigation analyzed the implementation and application of the Swedish National Archives' new Process-Oriented Archives Description Model to activities of the hierarchical, function-oriented and decentralized university organizations.The basic reason why a new archive description has evolved is because documents are becoming more and more digital. It requires a new interpretation of how evidence is secured for their reliability and authenticity, and a new way of looking at provenance, for the purpose of describing and searching electronic documents. The new archive description model's logical structure is based on business processes.The relationship between the new archive description and a function-oriented organization's activities can be seen from the different outlooks of processes between archive activities and activities of the organization. It is also reflected in the modification that all universities have made ??of the new archive description model to be more flexible and pragmatic to fit a function-oriented organization.The relationship between provenance and process-oriented archive description is mainly the link between documents and business processes that produce them.
