Obtaining high quality textile fibre from industrial hemp through organic cultivation
AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.
Identifiering och kvalitetsbedömning av mineral genom Ramanspektroskopi
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.

"Män skriver inte om tamponger" : En undersökning om människors bild av skribentens kön
The main purpose of this essay is to identify opinions of masculine and feminine language in a written text. The aim is to examine whether the reader of a text can define the anonymous author?s sex, judging only by elements such as choice of words or sentence structure. Are there any differences between the sexes as they appear in written language, and is the common man able to make this distinction? The essay is based on several studies on people?s ideas on masculine and feminine language, as well as studies on actual differences.
Undervisning i naturkunskap, demokratiuppdraget och interkulturell pedagogik : Kan en interkulturell pedagogik öka intresset och motivationen för ämnet naturkunskap bland elever på samhällsprogrammet?
Since studies points out declining interest in science among students in Swedish schools, I have in this paper chosen to examine how some students at the Social Science Programme are experiencing the lessons in Natural Science and how to make lessons more interesting according to these students.The purpose of this study was to gain a greater understanding of how teachers would develop new perspectives and tools to make lessons in Natural Science more interesting. I also wanted to investigate whether an intercultural perspective could be a possible tool to increase students? interest and motivation.As a theoretical framework, I have assumed Vygotskij's sociocultural perspective, Habermas's theory of deliberative conversations and an intercultural perspective. Through a qualitative approach, I conducted interviews with students and teachers. The main results showed that students felt that natural Science lessons were too theoretical and undemocratic and that they wanted to have more student interactions, such as discussions and group works.
Med sinne för detaljer : En domänanalytisk studie av ämnet Textilvetenskap vid Uppsala universitet med fokus på föremålsdokumentation
The aim of this two year master thesis is to study the knowledge production within the field of Textile Studies at Uppsala University, with special focus on the use of artifact documentation as a research method. With domain analysis as a theoretical framework, ontological and epistemological assumptions as well as historical and social aspects are studied in relation to the research process. Qualitative research methods are used, including interviews, observations and text analysis. In the analysis of the knowledge processes in the field, perspectives on tacit knowledge and the concept of documents, are used as a theoretical basis. In the field of Textile Studies, the artifacts are used as one of the main objects of study, along with archival and pictorial sources. The main epistemological assumptions are that artifact analysis is dependent on a knowledge base, where technical handicraft skills, contextual knowledge and practical experience of object observation are the most important qualifications.
Bilden i bilderboken
In this thesis I investigate aesthetic preference for picture books among children aged 3?6 as well as criteria for preference among parents. Through my design project: illustration of a picture book, I aim to put my research on preference in the context of illustration and design. By using the design project as an applied method for research I have sought to answer how one as an illustrator can apply knowledge regarding preferences of the target groups when illustrating for picture books. I have primarily based my research within the field of cognitive developmental psychology, with primary focus on stage theory, and the field of literature.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Service i privat sektor ? En kvalitativ studie om servicearbetarens upplevelse av sitt jobb
The aim of this qualitative study of service work in the private sector is to examine how the service worker experiences his/her work. There are three dimensions of the service workers experience in focus, and they are the base of my formulation of questions. The first dimension refers to how the service worker experiences the emotional labor demands from the employer. The second dimension concerns the relation between service worker and customer, from the view of the service worker. The third dimension problematizes how service workers experience efficiency.I have interviewed three call center customer workers and two hotel receptionists, using semi-structured interview technique.
Hur ska jag ta mig till skolan annars? : En kvalitativ studie av organisationen kring skolskjuts i Norrköpings kommun
This thesis concentrates on the organization surrounding the school transports in Norrköping and its surrounding areas. It is a qualitative research based on interviews with four different groups that is included by this organization, local municipal officials, entrepreneurs, school personnel and youths depending on this service. I have used organization theory as a theoretical base. In my study it became clear to me that this is a complex and multifarious organization. The many different actors sometimes make it hard to survey all the different parts of the organization.

The purpose with this essay is to investigate whether the legal capital can be justified as creditor protection and whether the legal capital prevent entrepreneurship.Historically the legal capital has been justified by means of creditor protection. Nowdays the development within EU rather reduces or abolish the legal capital. Sweden has recently, 1 of April 2010, reduced the legal capital from 100 000 Swedish crowns to 50 000 Swedish crowns. In the preparatory work it has been admitted that the legal capital does not in reality offer creditors much protection. Although the lawmaker decides to retain the legal capital and justifies the legal capitals existence with the argument that involuntary creditors has the need of the legal capital.

Den kulturpolitiska forskningens intellektuella bas och inriktningar ? En författarcociteringsanalys av artiklar publicerade i International Journal of Cultural Policy 2002-2007
The aim of this thesis is to map the intellectual base, and identify the general research interests, of Cultural Policy studies. In addition to this the thesis also aims to trace the uses of theoretical and conceptual approaches within the identified research interests. This is done by analysing citations from 130 articles published in the leading scientific journal International Journal of Cultural Policy between the years 2002-2007 using the bibliometric method author cocitation analysis (ACA). The results of the ACA confirm the overall notion that the research field of cultural policy studies is an ambiguous one, even when it?s studied with a quantitative method specialised in uncovering hidden structures within a given field as ACA.
