BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.

Den felande länken : Urval och kvalitetssäkring av Internetlänkar på folkbibliotek

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.

Etiska aspekter av preimplantatorisk genetisk diagnostik och genterapi

The research in the field of biotechnology is rapidly developing all over the world. Modern biotechnology offers unique opportunities, simultaneously as it gives rise to a number of ethical issues. Preimplantation genetic diagnosis (PGD), PGD/HLA (Human Leucocyte Antigen) and germline gene therapy (GLGT) are controversial techniques. PGD gives a possibility to identify a genetic disease prior to the embryo?s implantation in the uterus.

Från Lev Tolstoj till Joe Wright : En adaptionsstudie av Anna Karenina

This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.

Konvertibla Lån på den Svenska Marknaden: En studie av sex konvertibelemissioner

Issuing convertible bonds for financing purposes has never become widespread practice amongst Swedish companies, in spite of the instrument being common in international markets. Economic theory based on efficient markets suggests that companies should gain no financial benefits from using convertibles and the Swedish situation could be interpreted as in line with this reasoning. However, there are Swedish companies that have chosen to issue convertibles and the Swedish market therefore seems both supportive and contradictory to the existence of benefits of convertible bond financing. Little research concerning the Swedish market has been conducted and the purpose of this explorative thesis is thus to enhance the understanding of the Swedish market for convertibles. This is achieved by conducting in-depth interviews with six listed Swedish companies that have recently issued convertible bonds.

En likvärdig skola? - Om läromedel och kursplaner i grundskolans musikundervisning

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.

Industriell produktion av ljusemitterande vävar

Denna rapport beskriver ett examensarbete där optiska fibrer av plast integrerades i varpled i en väv. Syftet med examensarbetet var att undersöka om det är möjligt att industriellt producera ljusemitterande vävar med optiska fibrer. Arbetet delades upp i olika delar, både teoretiska och praktiska. 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.

Textila material

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.

Hur väljs spelfilm? Urvals- och inköpsprocessen hos Bibliotekstjänst samt urvalsprocessen hos svenska folkbibliotek

The main purpose of this thesis is to examine the process of selecting films at Bibliotekstjänst and at Swedish public libraries. The tools that have been used for analysing and interpreting the results from the interviews and the questionnaire are theory-based models describing the selection process concerning film and Carl Gustav Johannsen?s quality definitions. The result of the investigation shows that Bibliotekstjänst doesn?t really work with any quality definitions in their selection process.

Talande Toner : En studie om förskollärares uppfattningar angående tidig språkutveckling.

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.

Barn väljer medier : Erfarenheter från tio projekt där barn medverkar vid medieurval på folkbibliotek

The aim of this Master's thesis is to investigate why and how projects with children participating in selecting media at children s sections are made and how the projects effect the collections and the usage of these collections. We have studied literature dealing with how the selection at children s sections traditionally are made, how children participate in society and the question of quality. We have also made a survey to find out whether it is common to do projects like this in Sweden. In addition to this we have studied the discussion of patrons participating in library activities, having found mostly Danish material. Our study deals with five Danish projects, the reports of which we have read, and five Swedish projects, whose responsible librarians and assistants we have interviewed.

Superhjälte eller hjälplöst offer? Vem är vem? : En genusstudie av kvällspressens offerkonstruktioner efter skjutningen på Utöya.

On July 22nd 2011, there was a terrorist attack in Norway. First a bomb exploded in the Parliament House, in Oslo; and shortly after that a man shot 69 politically active young people at a camp on the island Utöya. Throughout the weeks to follow, we could read about the victims' stories. They told of tears, fear and heroism. But who got to tell what? The purpose of this study was to see how the Swedish tabloids described the victims from a gender perspective.

Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Blood compatibility of biomaterials made of recombinant spider silk

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..
