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.

The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.

In order to get a better understanding of the interaction between employees and their technical work tools one needs to know what factors influence the interaction. The purpose of this study was to examine if there is a correlation between the personality traits Extraversion (E) and Neuroticism (N), tested with Eysenck Personality Inventory (EPI), and experience of the new Intranet among employees at The Swedish National Transport Administration (SNTA), and also to gather information of employees? opinions about the new Intranet. A survey, containing questions about the Intranet and a personality test (EPI), was posted on SNTA?s Intranet for eight workdays (N = 88, females = 53, males = 35).

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

This candidate thesis contains the possibility of expand the Swedish photovoltaic market through photovoltaic cooperatives and a photovoltaic exchange. In the current situation there is a lot of problems with production of electricity from photovoltaic, that?s why we show some possibilities how to avoid these. To understand the problem with photovoltaic produced electricity we first give you a background.We show how to expand the Swedish photovoltaic market by describing how a photovoltaic cooperative and photovoltaic exchange could work in Sweden. It have been confirmed from our market research that the interest of photovoltaic cooperative and exchange is high.To find out how profitable photovoltaic is in Sweden, have three projections been made.

The aim with this study was to gain knowledge about how parents who are visual impaired experience and manage the meeting with the world around them. To have children and to be visual impaired creates a complex situation. There is not only the problem how to manage the parenting in technical terms. The disability is also filled with stigma because it diverges from the norms of society. There is not only demands from society about how the parent should behave, the parent also create demands of themselves.

The aim of this thesis is to identify some of the obstacles to trade, that occurs on the common market, and to analyse the errors that still occurs in the national authorities application of the principle of mutual recognition. Is the principle of mutual recognition sufficient for the creation of a common market, or is there a need for additional measures to cope with the obstacles to trade that still exists on the common market? The problems related to the incorrect procedures of the national authorities and the fact that undertakings prefer to bring their products in to line with the rules of every single member state must be solved, if the principle of mutual recognition is to become trustworthy. On some areas, harmonisation ought to be chosen above the principle of mutual recognition, but in other cases an increased administrative collaboration, mandatory training for the national authorities or information campaigns intended mainly for undertakings could be the answer. The possibility to help undertakings to sue member states for damages should also be investigated.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

The purpose with this essay is to give the reader an insight into and to describe the Danish Work Environment Act in its current wording and then compare it with the Swedish Work Environment Act. The first part of the essay describes the Work Environment Act and after that I compare with the Swedish Work Environment Act. At the end of the essay I will give my own thoughts of the result of this essay. I have chosen not to describe some of the chapters of the Act, for example the chapter about technical means and materials, because of the less importance for this essay and of my own interest. I have also chosen not to make mention of individual professions.

This Master Thesis has been carried out in cooperation with Silva Sweden AB. A companywhich manufactures products like compasses, pedometers, headlamps, hiking poles and otherequipment for the out door life and navigation. The purpose of the project has been toassemble methods and models which support user involvement in Silva?s design process.Thus, to increase the number of products with purchasing power, enhance product quality aswell as increase foundation for new product ideas.The focus through out the project has been to assemble a pallet with methods for userinvolvement and from this select a few methods that will fit the company. The purpose of thepallet is to be accessible for the company during their work of change with the design processthat has been going on and will be in the future.

Haldex Barnes Hydraulics (HBH) is a company which produces hydraulic aggregates for use in forklifts, construction equipment, and trucks. The last two years the company has expanded. This has lead to an insufficient production of aggregates. Thus wishes HBH to increase their production without making to large investments.This report includes a now-state analysis of the problems and where they are. From this a further analysis of possible improvements are made.HBH works mainly with assembling and this is made manually.

AbstractThis essay investigates what knowledge members of staff in day care centres for grown up people with disabilities have about Alternative and Augmentative Communication, AAC (in Swedish, Alterantiv och Kompletterande Kommunikation, AKK). Day care centres are working places for people with disabilities who do not have the possibility, caused of their disability, to work in ordinary works in the open market.To communicate with other people is a human right for all people even if you have a disability, even if you don?t have a spoken language or if you, because of your disability, have difficulties to understand a spoken language. When you don?t have a spoken language you need different ways to be able to communicate, make choices and take part in activities in the community.

This thesis focuses on the mass media cover of ?Smart textiles?. The Swedish?smart? textiles are developed in Borås and are a mix of ordinary textile and new technology.  I analyse the article with a text analysis method, looking at themes and the language?s propositions in focus. Context and the actors in the articles are also important in the analysis.Many women occur as developers of the new smart technical product, a field often knowed as a typical male subject.
