Planheten kan styras genom de planhetsställdon som valsverket är utrustat med. Syfte: Förvärva kunskap om hur de olika ställdonen inverkar på planheten. Varje enskilt ställdons inverkan på planheten kan undersökas genom att genomföra en föreskriven förändring av ställdonets läge och därefter utvärdera planhetsförändringen som uppkom.

This thesis investigates all aspects of quality and evaluation issues concerning collections of Internet links in public libraries today and in the future. We have studied central theories concerning quality in general as well as quality aspects regarding the Internet and Internet links. In addition to this we have made three case-studies involving the development of collections of Internet links in public libraries of different sizes. The case-studies were made as interviews with professionals responsible for selection, quality assurance and evaluation of electronic information for inclusion in the libraries collections of Internet links. In addition to this we made an e-mail interview with a librarian responsible for one of the most advanced collections of Internet links among Swedish´ public libraries.

This thesis is intended to review and create a greater understanding for the history and originsof printed scraps from late eighteenth century to the beginning of the twentieth century.A questionnaire survey was sent out to several Swedish museums, containing questionsconcerning their collections, possible exhibits, special difficulties and types of damagesconcerning scraps and their current storage. A visit to the Gothenburg city museum storagewas made to take a closer look at their scrap collection and how they were stored. Thisresearch resulted in an understanding regarding the current situation of printed scraps, whichunfortunately appears to be quite poor and inattentive. These results are presented in the firstchapter.The second chapter describes the history of printed scraps, followed by a chapter presentingrelevant printing techniques and technology. This is followed by various chapters dealing withhow the printed scrap has been used through the ages, history and development of motifs andthe album's significance.

Syftet med arbetet är att undersöka hur musiklärare tolkar målen i kursplanen i musik och hur de applicerar dessa tolkningar på sin undervisning. Syftet är även att ta reda på hur musiklärare använder sig av läromedel för att nå dessa mål. Bakgrunden till ämnet är tankar som jag har haft angående musikundervisningen på grundskolans lägre stadier och huruvida denna undervisning är likvärdig över hela landet. Skulle det vara möjligt att ett läromedel i musik, skapat utifrån de nationella målen i kursplanen, åstadkommer en sådan likvärd utbildning? Mina forskningsfrågor syftar till att kartlägga användandet och behovet av läromedel i musik och dessutom till att förstå hur målen i kursplanen för musik kan tolkas av olika lärare.

Den teoretiska delen innebar informationssökning inom olika medier, såsom vetenskapliga artiklar och intervjuer med insatta människor inom de berörda områdena. Den praktiska delen i examensarbetet bestod av flera olika moment.

Under ett samarbete med underklädesbutiken Bornevings har information om textila materialtagits fram. Butiken erbjuder alltid god service när det gäller utprovning av plagg men saknarbaskunskaper om textila material och hur de tillverkas. Textil informationen har tagits framför att underlätta detta problem. Kunskapsbristen kommer nu att eliminerats så personalen kanerbjuda den bästa servicen.För att få reda på hur informationen på bästa sätt skulle redovisas för butiken studeradespedagogik. Inlärning fungerar olika för alla, vissa tar till sig bilder medan andra lättare kanregistrera text.

Abstract The purpose of the study is to examine how children perceive the relation between play and sex and analyse it from a gender perspective. This by answering the questions: "Is the children?s choice of place, materials and company in play dependent on gender?" and "Is there a significant difference between the sexes and/or ages?" The study was done through twelve focusgroup interviews with three children in each group except two groups of two children in each. Eight boys and nine girls of six years old and nine boys and eight girls of nine years old were interviewed. Boys and girls were interviewed in separate groups and the questions were open ended and followed up.

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

The purpose of this essay is to examine one of Sweden's oldest motorways in cityenvironment. The researched section is motorway E20 east of Gothenburg. Olskroksmotetin the west and Jonsered junction in the east, a distance of about 11 km. The mainquestion was, can maintenance of areas and objects related to the motorway give greatermeaning to a system that currently lacks historical connection?The survey was partly an archival study and partly a physical examination of themotorway and its appearance today.The road through Säveedalen from Gothenburg has a long history that begins with theriver and its valley as transport routes.

The purpose of this study was to gain greater knowledge of how preschool teachers and children using an experimental- and activity box in biology. To find this out, I have used the participant observation method and semi-structured interviews since my study is qualitative. The result of the work led to a greater understanding of the biologybox. It was shown that preschool teachers' involvement is very important for children and that the biologybox contained good and inspiring materials. Although educators desired that there was more material to choose from as well as the usage time of the biologybox should be longer than 3 weeks..

The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

The Regional State Archive in Uppsala [Landsarkivet i Uppsala] has several archives left from various types of educational institutions in the counties of Dalarna, Södermanland, Uppsala, Västmanland and Örebro. This archiv-al guide reveals the main content of some of the school archives. It goes through the archives of the elementary school, state secondary grammar schools and private secondary grammar schools. A few special schools for the blind and the deaf children are included. The essay also brings up records from community homes and reformato-ries for children and young adults who experienced certain difficulties and therefore could not adjust to the ordi-nary educational system.
