Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Oral intake of green tea and its effect on the appearance of UV-induced erythema, erythema solare ? A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.
Utvärdering av den nationella söktjänsten LIBRIS
LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.

Syns du finns du? : En studie över användningen av SEO, PPC och sociala medier som strategiska kommunikationsverktyg i svenska företag
Syftet med arbetet var att undersöka hur lärare och elever interagerar med varandra och hur det naturvetenskapliga innehållet presenteras och kommuniceras under en naturvetenskaplig lektion på gymnasiet. Studien ingår i det nordiska forskningsprojektet Explora som arbetar med naturvetenskaplig undervisning och som har tagit fram en kodbok för detta ändamål. Utgångspunkten är sociokulturellt lärande, där kommunikationen är viktig för lärandet, där lärande innebär att socialiseras in i en diskurs och att språket används olika i olika kontexter. Undersökningen var till största delen kvantitativ och deduktiv men med kvalitativa inslag. Kodboken användes som analysinstrument och därmed gjordes en slags innehållsanalys.
Effektivisera materialflödet med hjälp av självgående truckar
The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

BCAA-supplementering i samband med levercancerkirurgi
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: BCAA supplementation in patients undergoing resection for liver cancerAuthor: Mikael Semaan and Viktor SjölingSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013BackgroundLiver cancer is the fifth most common cancer worldwide and the third largest to cause death. Protein-energy malnutrition is common in patients with liver disease and they often suffer from changes in the hepatic metabolism of nutrients and other substances. There is a basis for recommending BCAA supplementation in other certain liver diseases. Given the similar clinical picture of liver cancer surgery, it is possible that supplementation of BCAA can be beneficial for these patients as well.ObjectiveThe aim was to study the scientific basis for the effect of branched chain amino acid (BCAA) supplementation in liver cancer patients. Can it improve their recovery in terms of nutritional status and albumin levels, and does it changes the duration of hospital stay, after surgery?Search strategyFive extensive searches were performed on PubMed and Cochrane after appropriate study material.
Lost in translation? En empirisk undersökning av användningen av tesaurer vid queryexpansion inom Cross Language Information Retrieval
The purpose of this thesis is to examine the performance of queries that is expanded before translation in comparison with only translation of the queries using a bilingual dictionary, and also to see if the number of terms that was used to expand the queries was of any importance i. e. if many terms from a thesaurus helped or destroyed a query. To answer these questions i used two online thesauri, Rogets thesaurus and Merriam-Webster Online and one printed bilingual dictionary, Norstedts English-Swedish dictionary. Even though the number of examined queries is too small to draw any definite conclusions, the results suggest that expanding using a general thesaurus may have a negative effect on the queries.

Stereotyper i toner : Musikens roll i konstruktionen av stereotyper i svensk film under 1990- och 2000-talet
The aim of this paper is to investigate what part film music plays in the creation of stereo-types in the production of Swedish cinema, in the 1990s and early 2000s. This period of Swedish cinema was largely defined through the visualization of life in the smaller provinces of the country. The results were reached through the analyzing of four important works of this era, representing different provinces and genres. The examined movies have shown frequent use of extreme characters and a somewhat hostile environment in search of an interesting story. The music is used in ways of describing class differences amongst the inhabitants and to set the gen-eral mood of the concerned provinces: an agent often working in the unconscious of the viewer in order to affect the final results..
