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.

This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

The aim of this paper was to investigate how 40 typical speakerswith Finnish accent, aged 65-84 years, performed in speech assessmentthrough Dysartribedömningen, a Swedish dysarthria assessment instrument.Their results were compared with results of a matched Swedish nativespeaking reference group. Both groups were assessed in areas offunction/structure, prosody/intelligibility and through a survey oncommunication. Results indicated that the performances of the Finnishparticipant group were estimated as more deviant than the Swedish,considering all areas. The Finnish participants were deviant in articulationand they had a significantly lower speech rate in reading. They also hadsignificantly lower scores in intelligibility compared to the reference group.The results of the survey of communication showed that the Finnishparticipants estimated their levels of activity and participation to besignificantly more limited compared to the reference group.

Being an immigrant in a Swedish school today might not be easy. It´s quite difficult to be accepted and becoming a part of an already functioning group. Difficulties with the Swedish language doesn´t make it easier. Besides that the requisites of the school curriculum program are very demanding and Swedish students are often in advantage already being a part of the system for many years.By following five immigrant boys in grade 6 during ten ensemble lessons, one concert and individual interviews with the boys as well as with their teacher, this study aims to investigate how ensemble playing can function as a social tool and promote interaction as well as integration.The results in this study show that ensemble playing in fact can function as a social tool. The boys developed abilities in playing an instrument as well as cooperating and analyzing by using the social tool of ensemble playing.The results even show that ensemble playing can promote interaction as well as integration.Above everything was the concert where the boys acted in front of their classmates and were treated with great respect and acceptance..

MedView-projektet, som startades 1995, är en av många organisationer som söker webbasera sin information. Projektet är ett tvärvetenskapligt samarbete mellan disciplinerna oral medicin och datavetenskap och inom projektet har en samling av applikationer tagits fram som kan lagra samt presentera data. Den insamlade informationen sparas i en filbaserad kunskapsbas.Tanken är nu, vilket angavs i projektets anslagsansökan till Vinnova 2003, att webbasera denna kunskapsbas så att kliniker inom oral medicin samt andra intresserade inom området skall ha tillgång till informationen. Detta arbete behandlar framtagandet av en central webbplats med ett tillhörande behörighetssystem.I detta arbete visas att UNIX behörighetsmodell kan användas som utgångspunkt för att skapa ett webbaserat behörighetssystem samt att de krav som identifierats kan implementeras tillsammans med behörighetssystemet i en central webbplats för MedView.

Bakgrund: Astma är en kronisk inflammatorisk luftvägssjukdom som är vanligt förekommande i alla åldersgrupper. Över 300 miljoner människor världen över beräknas ha sjukdomen.Syfte: Syftet med litteraturstudien var att undersöka om den orala hälsan hos barn med astma skiljer sig från den orala hälsan hos barn utan astma.Metod: Metoden som användes var en allmän litteraturstudie och litteratursökningarna gjordes i den medicinska databasen PubMed. Resultatet baseras utifrån en sammanställning av 13 vetenskapliga artiklar. Artiklarna var kliniska studier och 11 av dessa hade en kontrollgrupp där barn med och utan astma jämfördes. Övriga två artiklar studerade antingen hur den orala hälsan påverkades av kombinationsbehandling med specifika läkemedel eller jämförde den orala hälsan hos barn med olika duration och medicinering mot astma.Resultat: Några av de inkluderade studierna fann att barn med astma hade en ökad kariesförekomst jämfört med barn utan astma, medan andra studier visade att det inte fanns någon skillnad mellan grupperna.

In this thesis I set out to study how the reading of fictional literature is viewed, legitimatized and operationalized in two educational domains: the recently revised steering documents that all Swedish teachers must relate to, as well as a selection of teaching materials designed for education in the Swedish language for upper secondary school. The teaching material I have studied has been recently updated in order to correspond with the new steering documents. I relate my analysis to previous research about the use of fiction in education, and I also combine my analysis of the two educational domains to see whether the underlying intentions of the steering documents have influenced the revision of the teaching material. The outcome indicates that the steering documents? previous focus on culture has diminished although a certain insecurity as to how to use the concept and deal with the issue of whose culture should be taught can be identified.

The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Syftet med denna studie var att undersöka sambandet mellan några lärares bedömning och olika pedagogiska grundteoriers kunskapssyn samt hur de tillsammans med lärarens egen kunskapssyn påverkar bedömningen. Utifrån uttalanden från 5 stycken utvalda lärare, tillsammans med den litteratur som vi läst har vi försökt att hitta samband. Den metod som användes var enskilda intervjuer, ur vilka uttalanden kopplades till den litteratur och de pedagogiska grundteoriernas kunskapssyn. Vi ställde frågor om hur dessa personer konstruerade sina prov samt hur de bedömer och dokumenterar sina elevers lärande. Hur lärarnas bedömning påverkats av de olika teoriernas kunskapssyn och hur skolväsendet har påverkats av dessa teorier försökte sedan knytas till behaviorism, kognitivism, konstruktivism och sociokulturell teoris olika kunskapssyner.

Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

This thesis examines trust on the web. W3C is a consortium of organisations focusing on development of standards for web publishing, and one of their projects within the semantic web track is web-based annotations. The purpose of the investigation at hand is to evaluate to what extent different factors are being considered when webbased information is judged, and whether web-based annotations could serve as a confidence-inspiring tool. The main research question was therefore: How do the informants experience Annozilla as a possible confidence-inspiring tool? The empirical material consists of a case study with eight informants.

Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures.

In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.

The purpose of the study was to examine if Talking Mats® couldsupport communication and participation for people with Huntington?sdisease, carers and a dental hygienist in conversation about oral care.

Feelings of participation increased forall participants and were significantly higher for participants withHuntington's disease.

The essay treats how a process of implementation was executed and the teachers? relation to two curricula, Lpo94 and Lgr11, with two different grading systems, which have functioned as models for one and the same year. The purpose is to investigate the ways in which a change in curricula and syllabus affects teachers in their teaching and assessment practice in the subject of Swedish at secondary school. The investigation had a phenomenological approach and was executed by means of in-depth interviews, questionnaires and one observation. The results are based on a methodological triangulation with qualitative and quantitative data where visible similarities and differences are brought out.
