Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.

SAMMANFATTNINGSyftet med studien var att undersöka patienters inställning till att dela rum med patienter av motsatt kön och ålder. Metoden som användes var en deskriptiv tvärsnittsstudie med kvantitativ ansats som utfördes på två akutkirurgiska avdelningar. Det var 33 inneliggande patienter som deltog i studien. En studiespecifik enkät delades ut med tio frågor och två frågor om kön och ålder. Frågorna rörde olika synpunkter om hur det är att dela rum med andra patienter och om hur det är att dela rum med patienter med motsatt kön och ålder.

Insomnia is getting more prevalent with age, both because of natural changes in the sleep pattern and because of increased morbidity. It can cause dysfunctioning and sedation during the day. Therefore it is often treated with hypnotics. It is possible though that hypnotics can cause daytime sleepiness as well, not to mention increased risk of falling and fractures because of sedation and prolonged reaction time. Benzodiazepines and benzodiazepine related drugs, the subjects of this study, are commonly used as hypnotics.

The aim of this study is to find out what education in literature is like from a student perspective; what kind of literature the students read and how well they understand literature, and the methods and didactics used during the literature lessons. The questions at issue are:1) What kind of literature do the students read?2) How well do the students understand literary texts?3) What do the students think about their literature education?To be able to answer the questions, both quantitative and qualitative methods have been used in the study. The inquiry was accomplished on 29 students, 17 boys and 12 girls in the upper secondary school. The result showed, despite the limited amount of students, interesting facts.

The essay deals with the hill-fort on the mountain Halleberg, Sweden, its wall design, functionality, dating and its possible function as a central location and a place of worship of the ancestors.The Halleberg hill-fort consists of a 1500 meters long at times cohesive stonewalls which together blocked the mountain from its surroundings. Hallberg's natural vertical scree and cliffs along with the masonry blocked the whole mountain from the surroundings.The hill-forts, with few exceptions are largely not investigated archaeologically and its functionality and role in the ancient society is based on outdated research on the subject. The current archaeological interpretation is that hill-forts served as temporary defense in times of unrest or served as center of power for a social elite. The prevailing view in the archaeological sphere is that the hill-forts had a variety of functions and that its functionality and role in ancient society has varied.Halleberg´s strongest wall sections are at the mountain's south-eastern part where the natural driveway, Storgårdsklev is located. Along with the massive masonry of the walls in Bokedalen Storgårdsklev functioned as the hill-forts main entrance.

Zoo animals can be more or less disturbed by the presence of care takers as well as visitors. This may lead to stress and/or abnormal behaviour. The purpose with this study was to give a time budget of the behaviour of the captive wolves? (Canis lupus) and occurrence of behavioural disturbances and how this is affected of human visitors. For this purpose the wolves at Nordens Ark have been studied during off season as well as on season. The zoo Nordens Ark is an idealistic foundation which was founded in 1988 and is located at Åby säteri, 130 km north of Gothenburg.

Purpose of this thesis is to study the impact of wind turbines on their surroundings. It also aims to analyze how the communication looks between the authorities, the planner and local residents prior to the establishment of wind turbines in Lännäs/Odensbacken in Örebro, where three wind turbines set up in a group.The results of this survey show that the participants experience themselves not as especially disturbed of the turbines in the form of large noise, shadows, and sleep disturbance indoors and outdoors. Participants felt that no change had taken place on the natural environment (52%) since the turbines became operational. It was 49% of participants had got no information about the establishment of Örebro Municipality, Örebro County Administrative Board or Wind Power Company. Scientists/­experts had the highest confidence of 86%, politicians and the media/journalists had least confidence.

SAMMANFATTNING BakgrundAtt arbeta skift har visat sig vara en stressfaktor som påverkar både sömn och hälsa negativt och inom sjukvården kan även patientsäkerheten äventyras om personalen är utmattad på grund av sömnbrist.SyfteSyfte med denna litteraturstudie var att beskriva vilka faktorer som påverkar sömnen och kan medföra sömnstörningar, samt vilka preventiva åtgärder som kan leda till förbättrad sömn hos skiftarbetande vårdspersonal.MetodResultatet bygger på tio vetenskapliga artiklar publicerade under åren 2007-2013. Dessa söktes genom databaserna Cinahl, PsykINFO och PubMed.Resultat I analysen av artiklarna framkom att skiftarbete som inkräktar på normala sömntider har en uppenbart skadlig effekt på sömnen med svårigheter att somna och sömnighet under både arbetstid och ledighet. Utmärkande var att stigande ålder och låg stresströskel (hardiness) ökade risken för sömnstörningar. Att ges möjlighet till tupplur under nattpass var en viktig åtgärd för att förebygga trötthet och främja hälsan hos skiftarbetande vårdpersonal.SlutsatsEftersom skiftarbete i sig har en uppenbart skadlig effekt på sömnen så är det av största vikt att ge vårdpersonalen bästa möjliga förutsättningar för att bibehålla sin hälsa på sikt. Förutom att planera för bra skiftscheman med schemalagd rast samt möjlighet att sova på nattpassen, bör man ta hänsyn till vårdpersonalens ålder och stresstålighet (hardiness)..

Jönköping Small Animal Hospital is today the only clinic in Sweden to offer radiation therapy as a treatment of tumours. The body contains of billions of cells that all have to obey the regulations that are established. If a cell is exposed to a harmful substance, for example a chemical, it can be transformed into a tumourcell. Normally the body has a good defence but the tumourcell can survive and start to divide unrestrained. A tumour is starting to develop.

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

The health care sector Öster has the highest average absence due to short-time sickness in Örebro. It is the short-term absence that has the highest costs for the organisation, not just in money, but also in quality disturbances and administrative work. Health care sector Öster is divided into four areas with a manager for each. We have chosen to conduct our research within the special housings in area one and four, since these two had the lowest and highest short-term absences.The purpose with the research is to examine short-term absences among the health care personnel in the health care sector Öster, see what the absences depend on, and what can be done to solve the issue. We will compare the absences in the area with the highest respectively lowest short-term absences in order to see if there are any prominent differences between the two.

Bakgrund: Sömnens påverkan på viktkontroll har större betydelse än vad forskarna tidigare trott. God sömn innebär återhämtning av livsnödvändiga funktioner och är en grund för god hälsa. Studier visar att människor sover mindre idag jämfört med tidigare. Sömnens påverkan på viktkontrollen behöver lyftas fram i sjuksköterskans hälsopreventiva arbete för att främja hälsa. Syfte: Att belysa sömnens relevans för viktkontroll hos medelålders vuxna.
