Hårdfräsning i verktygsstål : Förslitning av skäregg
This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool steels: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool steel alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder steel with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

Bostadsbubbla i Stockholm kommun : Sann existens eller falsk spekulation?
In light of the massive property bubbles that have been bursting in the USA, Spain and Ireland during the last decade, the aim of this thesis is to clarify whether ? or to what degree - the municipality of Stockholm might experience a property bubble in the near future. The municipality of Stockholm is undergoing a housing shortage and house prices have risen during the last few years. Neoliberalism and property bubbles are used as a theoretical framework in this paper. The methodology consist of semi structured interviews, analysis of documents and statistical data from Eurostat, Valueguard and the Swedish administrative authority; Statistiska centralbyrån (SCB).
Rätt person till rätt plats : En studie om hur personal rekryteras till behandlande organisationer i Örebro
Known to be one of the most important resources, but also one of the most difficult ones to obtain, the workforce constitutes (consistence) the core of any organization. To find the right person for a particular position is not a trivial task. The recruitment of new staff members is important for any organization in general, but for treating organizations in particular. In order to provide the best service for its clients, it is, for a treating organization, vital to recruit nothing but highly qualified personnel. A well educated workforce can more easily stick to the treatment program and thus maintain treatment integrity.
Jämförelse av resultat mellan manuell gelkortsanalys och automatisk immunohematologisk gelkortsanalys vid utförande av blodgruppskontroll och antikroppsscreening (BAS-test)
Incompatibility between donors and recipients can cause fatal hemolytic transfusion reactions (HTR), kidney damage and death and immunization of the recipient. Antigens on the surface of erythrocytes in the ABO blood group system and regular natural antibodies against these in the patient?s plasma must be considered. An individual always has a corresponding antibody of IgM in their plasma. Irregular antibodies acquired by transfusion or pregnancy and active in body temperature also cause the HTR incompatibility.
Flygteknik : Konceptstudie av ett obemannat flygplan
Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.
UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk
Lining techniques such as nap bonding and mist lining were developed in the late 20th century and
have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability
of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown
advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced,
which can be advantageous for more sensitive paintings. These lining techniques have been included
in several studies where reversibility, minimal intervention and respect for the individual requirements
and problems of each object have been the focus. The adaptability of the methods has been confirmed
and to further explore the adaptability, this study consists of three simpler application techniques with
the adhesive Lascaux 303 HV on mockups.
Bättre en bok i handen än tio på nätet? En studie av författares och förlags attityder till elektronisk publicering av skönlitteratur
This master thesis investigates attitudes toward electronic publishing of fiction among the key participants authors and publishers in Sweden with the overall purpose of analysing the nature of these attitudes and what sort of tensions that exist between the two groups. The major areas of concern were formulated as: what sort of attitudes do authors and publishers display toward electronic publishing of fiction?, how do these attitudes affect the way the two groups relate to electronic publishing and to each other? and how do they perceive the future of this practice?. Everett Rogers diffusion of innovations theory was applied to characterise electronic publishing as an innovation cluster, and to investigate innovation attributes in form of relative advantages and disadvantages, compatibility, complexity, trialability and observability. Data was gathered using quantitative questionnaires, but respondents were also given the opportunity to elaborate freely on some of the questions.

Allmänna rättsprincipers framväxt och påverkan inom EU - En uppsats om principerna med fokus på proportionalitet, rätten till försvar och offentlighet
General principles of law can be defined as a legal foundation with the function of codifying basic values. They can also be of a character, which makes them useful as supplement and interpretation of law. EU has developed principles of law that can be divided into general and special. Within the Union there are existences of around twenty general ones. A further separation can be made in terms of institutional and individual.
Utvärdering av klusteranalytiska metoder i kombination med bibliografisk koppling: en bibliometrisk kartläggning av aktuella forskningsteman inom informationsvetenskap
The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

Breastfeeding and breast milk is considered to be the best nutrition for infants in general and for premature infants in particular. The premature infant, depending on how premature, may not be able to breastfeed effectively due to their immaturity. Stress, anxiety and fatigue are factors that affect breast milk production in a negative direction and these feelings are common in the neonatal unit.Aim: To illuminate mothers? experiences of breastfeeding the premature infant in the neonatal unit.Method: A literature review of eight studies with a qualitative research approach, published between the year 2000 and 2012 was conducted.
Miljöberikning av vithandad gibbonapa, Hylobates lar, Parken Zoo, Eskilstuna
The design of buildings is today considered to be crucial for obtaining sustainable development. Research concerning sustainable building is considered to be a Swedish area of strength and development projects as Hammarby Sjöstad and Bo01 are often pointed out as Swedish prime examples of sustainable building. Some still argue though, that that these projects should not be presented as sustainable, due to its incompetence to meet their objectives. This contradiction has attracted my curiosity. By doing this study I hope to gain understanding about the difficulties Bo01 and Hammarby Sjöstad are surrounded with and its significance for sustainable development.
