Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

Functioning reproductive organs are essential for the survival of a species. The reproductive system is very sensitive to exposure of chemical substances of anthropogenic origin. Humans release great amounts of chemical substances to the environment by our means of life and these substances have been proved to have a negative effect on the reproductive ability of different vertebral classes. In the polar bear (Ursus maritimus) a declined reproductive ability as an effect of decreased testosterone levels and decreased testicular size has been connected to the presence of high levels of organohalogenic compounds like PCBs. Although the Swedish brown bear (Ursus arctos) is not as carnivorous as its close relative the polar bear it is still exposed to environmental.

Hörntänderna i maxillan är efter visdomständerna de tänder som oftast blir retinerade. Prevalensen varierar mellan 1-3%. En retinerad överkäkshörntand har ofta en ektopisk placering. Detta kan leda till att eruptionsriktningen blir felaktig och därmed kan tanden orsaka skador på de angränsande incisivernas rötter. För att minska risken för detta krävs tidig diagnostik, i 9-11 års ålder. Den vanligaste åtgärden för palatinalt displacerade hörntänder är extraktion av mjölkhörntänderna för att underlätta spontaneruption av de efterföljande permanenta hörntänderna.

Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories. Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.

Problemställning och syfte: Bromerade flamskyddsmedel (BFR) används i många varor och produkter. Polybromerade difenyletrar (PBDEs) är en av dessa och deras kemiska struktur liknar den i miljögiftet PCB och kan på samma sätt lagras upp i miljön samt skada människor och djur. På arbetsplatser där BFR förekommer riskerar medarbetarna att exponeras. I den här studien har olika BFR undersökts i samband med servicearbete på flygplan. Målet har varit att jämföra förekomsten i damm och luft, samt blod (serum) med resultat från tidi­gare studier.Metod: Damm- och luftprovtagning har genomförts vid olika faser av service­arbetet.

Although known and feared for thousands of years, rabies remains a real and present threat to thousands of people, especially in low- and middle income countries. In India, rabies is an endemic disease, causing human deaths every year. The primary mode of transmission is through the bite of an infected dog. Fighting the disease in the dog population through vaccinations remains the most efficient way to eradicate the disease. The knowledge of rabies in India is unsatisfactory, as a lot of people lack awareness about the severity of the disease and the importance of washing the bitten area and seeking medical attention for post exposure prophylaxis when bitten by a dog.

The aim of this study was to analyse ninth graders self reported screen based activities, sedentary time and musculoskeletal symptoms and pain intensity. The other aim was to examine changes regarding musculoskeletal pain and inactivity between ninth graders from a cross sectional study in year 2004. To meet this aim, following questions were designed: How is the relationship between screen based activities, inactivity, musculoskeletal symptoms, pain intensity and differences between girls and boys? How have musculoskeletal symptoms and screen time changed since year 2004?Method: The method used for this study was a quantitative method. The research was carried out using a questionnaire that was answered by pupils from 11 schools from all over Sweden.

Since the 1970s voting behaviour has changed. Party identification and class voting has declined. As the electorate becomes more volatile, campaign strategy and party image becomes essential. Political communication and mass media now play an important role in election campaigns. Therefore, researchers take an interest in the impact of media on public opinion.

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. Trees at Djurgården, Stockholm that have been colonized by Plagionotus detritus has been studied to find out the habitat preferences of the species and to see what affects the density of beetles in a tree. The bark of some trees and wood from the breeding project at Nordens Ark has also been studied to find out what affects the species reproductive success. The reproductive success was measured in two ways, the larval mortality and the size of the hatching holes.

Dagens dynamiska situation på marknaden sätter spår på den befintliga marknadsfilosofin med fokus på kommunikationen mellan företaget och konsumenten. Den moderna teknologin och Internet har utvecklats och blivit mer tillgängliga, vilket har bidragit till att den moderna konsumenten tillbringar en stor del av sin tid på Internet. De digitala nätverken och kommu-nikationen inom dem förändrar konsumentbeteenden och attityder, främjar konsumenters självständighet samt ger kontroll över köpbesluten. De här trenderna påverkar dagens detalj-handel, där konkurrensen och kampen om kundernas lojalitet ökar. Konventionella marknads-föringsstrategier föråldras snabbt under dagens förlopp och kräver mer kreativitet och enga-gemang av företaget.
