Hepatit E - en zoonos?
Hepatitis E virus, HEV, is a frequent causative agent behind, especially waterborne, infections in developing countries such as India. However, during the last years the number of non-travel-associated infections in industrialised countries, for example US, Germany and Sweden, has increased. The symptoms vary from mild with nausea to icterus and it can even be lethal. There are four different genotypes of HEV and many studies consider HEV infection to be a zoonosis. Scientists have by using phylogenetic analyses found great genetic similarity between strains isolated from humans, pigs and food, such as pork and liver, especially among viruses belonging to genotype 3.
Barn med 22q11.2 deletionssyndromet ? hur hör de?
The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.
Kan förändringar i bottenfaunan påvisas två år efter en bäckrestaurering?
The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.
Myten om det mångkulturella samhället. En diskursanalys av mångfaldsrelaterade begrepp och etnicitet i svensk kulturpolitik
The purpose of this Masters thesis is to examine the discourses of concepts related to diversity and ethnicity in Swedish cultural policy. It focuses on how the society is presented in different contexts and how people with a different ethnic origin than the majority, are represented in the cultural policy of the Swedish State. The study is restricted to concern immigrants. Six governmental cultural policy documents, reaching over a time period of eight years 1995-2003 are examined as follows: Which key terms are used in the presentations? Which contexts and discourses can be distinguished? Have the discourses changed over the time period examined, and if so, how? The theoretical starting point in the thesis is the discourse perspective of Laclau and Mouffe.
TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis
Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .
"Var femte damernas" : undersökning av kvinnlig representation i styrelse bland företagen noterade på Large cap, Stockholmsbörsen
Sverige framställs ofta som ett av världens mest jämställda länder där män och kvinnor har samma möjlighet till inflytande och makt. Kvinnor på ledande positioner i Sverige har ökat de senast årtionden men när det kommer till högre positioner brister kvinnor i representationen, framförallt inom det privata näringslivet. Lönsamhetsargumentet har ofta används som ett skäl för att öka andelen kvinnor i börsnoterade styrelser och företagsledning, medan studier om diversifierade styrelser visar på ett blandat resultat både vad gäller lönsamhet och effektivitet. Syftet med denna uppsats är att undersöka representationen av kvinnor i företagens ledning på Large cap, Stockholmsbörsen men också se på hur denna representation kan förklaras samt hur mångfalden i styrelserna eventuellt kan utvecklas. Ett ytterligare syfte är att undersöka om det finns ett finansiellt argument om lönsamhet som kan motivera en ökning av andelen kvinnor i bolagsstyrelserna och om andelen kvinnor i nomineringskommittéerna leder till fler kvinnliga ledamöter i bolagsstyrelserna.
Spelroll "At Heart" : Spelrollers inverkan på erfarna spelares problemlösningsförmåga i vardagen
Games offer a safe and motivational environment that allows and encourages trial and error. A gamer can act in the game without any real consequences in real life. Thereby a gamer is offered the opportunity to develop a broad set of skills. Games have earlier been proven to develop gamer?s problem-solving skills.
Linderödsgrisen : en inventering av populationsstruktur och produktionsnivå
In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.
Den uppklädda människan : en diskussion kring den gropkeramiska klädesstilen
This thesis discusses the dress code during the Pitted Ware culture on the Swedish island of Gotland. Eight Pitted Ware grave-fields have been analyzed; only 74 skeletons have been identified with some sort of ornament that could have been attached to clothes. The grave-fields are rich in finds and in people nearly every age group is present. The analysis has shown that there are clear differences between the genders. The female always has some sort of seal tooth ornament around her waist and thighs.
Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease
Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.
Folkbiblioteket och individualiseringen. En diskursanalytisk studie.
The aim of this Master's thesis is to analyze the relation between the discursive formation and the optical formation in the public library-apparatus. An ongoing individualization process in the library field and in society at large is used as a backdrop in the analysis. Discourse analysis is used as a method to explore the main Swedish library periodicals Biblioteksbladet, Bibliotek i Samhälle and DIK-forum. All issues from the years 1999 and 2009 have been used as material. The main analytical instruments applied in the analysis of this material are Michel Foucault's terms dispositive, apparatus and diagram.
En studie i informationsgrafik : Designstrategier och principer för det animerade formatet
In the media richness of everyday life, the encounter with information graphics ishappening on a daily basis, whether we are aware or not. With the development andeasy access of technologies, new ways to create and display information graphics hasemerged. Among them, the animated information graphics, which in the few pastyears appears to have increased in popularity on video sharing websites such asVimeo and Youtube. In the genre of animated information graphics, there seems to bean inherent diversity regarding the design characteristics. In this study we exploredliterature and research on information graphics and related subjects.
En studie om hanteringen av Rasbiologiska institutets samling och känsligt material vid Uppsala universitet
The Swedish institute of racial biology was the first of its kind in the world. The purpose of their activity was to gather information about the different kind of racial characters of the Swedish population. They did this by traveling around the country gathering pictures and statistic information. In 1958 it was decided that the institute was going to get integrated with the University of Uppsala and change its research focus to a more medical genetic. Most of the research material also got integrated into the university?s library.The purpose of this paper is to find out how the institutes collection has been handled through the ages and if there have been any controversy or debate about it.
Diskurser om breddad rekrytering : Analys av några offentliga texter
The aim of this study is to investigate the discourses of widening recruitment to higher education in some political documents from the 21st century. The scientific method applied is critical discourse analysis as developed by Norman Fairclough. This implies the analyses of the actual texts, the social practice as well as the discursive practice, i.e. the conditions under which the texts are produced, distributed and consumed.The major results include four discourses: a post-modern discourse, a neoliberal economic discourse, a political discourse of multi-culturalism and a modern discourse with its roots in the 20th century?s discussions about social imbalance in recruitment to higher education.
Nysvenskan - hur etnisk mångfald påverkar innovationsförloppet på en dagstidning
Studiens syfte är att utreda om och i så fall hur etniskt mångfald påverkar innovationsförloppet på en dagstidning. Vi valde att använda oss av en kvalitativ metod med en abduktiv ansats utifrån vilka vi utförde nio semistrukturerade intervjuer. Som verktyg för vårt syfte användes Sydsvenskan som fallföretag, i strävan efter att kunna generalisera resultatet på branschen.Vi har använt oss av innovationsteorier för att förklara synen på innovationsförloppet, samt mångfaldsteorier för att teoretiskt kartlägga hur mångfald påverkar olika konstellationer av människor. Det empiriska materialet består av intervjuer med anställda på olika befattningar inom fallföretaget samt externa fackmän inom ämnet innovation och mångfald. Resultaten visar på vikten av etnisk mångfald på en dagstidning, där den interna mångfalden tillhandahåller den externa mångfalden med en verklighetsbaserad och innovativ tidning.
