This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

As Sweden has become a multicultural society the need for developing new educational approaches rises. The preschool is a crucial piece in this as it is the one of the first institutions where the children start to develop the language skills. The aim of this study is to investigate the language development approach as practiced by teachers, in their preschool programs, and determine if the teachers work methods can be considered intercultural. This is done to gain a deep understanding on several language development methods and analyze the teachers' approach within the framework of intercultural pedagogy perspective. The theoretical framework used in the study is the intercultural perspective.

Bakgrund: Barnfetma är idag ett världsomfattande problem. Överviktiga barn och ungdomar har större risk att bland annat utveckla diabetes typ II och hjärt- och kärlsjukdomar. Syfte: Belysa arenor för prevention och promotion mot övervikt och fetma bland barn och ungdomar mellan 7-17 år. Metod: Studien som gjorts är en litteraturstudie. Databaser som användes var PubMed, SweMed+ och Cinahl och artiklarna analyserades genom en temaanalys. Resultat: Studier visade att främst på arenor som skolan, hemmet och samhället kan övervikt och fetma förebyggas bland barn och ungdomar.

Bakgrund: Övervikten i den svenska befolkningen och i västvärlden har de senaste 25 åren ökat och gått allt längre ned i åldrarna. Övervikt och fetma utgör en riskfaktor för sjukdomar av såväl somatiska som psykosocial karaktär.Syfte: Litteraturstudiens syfte var att beskriva hälsopromotiva interventioner för barn och ungdomar.Metod: En litteraturstudie med artikelsökning och granskning utifrån syftet gjordes. Fem kvantitativa och en kvalitativ artikel inkluderades efter kvalitetsbedömningen.Resultat: Resultatet visar på att problemet med övervikt måste ses ur flera perspektiv och åtgärdas från flera håll. Mönster som växte fram var: skolpersonalens interventioner, föräldrars interventioner, hälso- och sjukvårdspersonalens interventioner samt andra aktörers påverkan. Interventionernas tyngdpunkt ligger på kost och motion.Slutsats: Framförallt en god kosthållning och fysisk aktivitet är viktiga faktorer för en lyckad intervention.

The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

Vad försöker man göra inom ungdomsinriktad drogprevention och vad uppfattas som viktigt? Syftet med denna studie var att undersöka vad som händer inom preventionsarbete i Thailand. Analys med grounded theory av intervjuer med 27 personer, främst thailändare, med praktisk erfarenhet av drogpreventiv verksamhet. Motkrafter till missbruk i Thailand genomsyras av en moraliskt betingad grundhållning med en i grunden autonom människosyn. Genom sociala och pedagogiska nätverk, positiva alternativ, utveckling, relevanta budskap och kritiskt tänkande arbetar man med målgruppen för de preventiva insatserna som en autonom och aktiv part.

The aim with this study is to understand how social workers at the individual- and family sector think about child poverty and how they work with and reason about the preventive and facilitate work they do for financial vulnerable families. We have in our study used qualitative method through semi-structured interviews with social workers at the individual- and family sector to answer our purpose. The results showed that child poverty is a concept hard to define and not well established. The social workers have divided views on child poverty but still at the same time mean that it exists amongst the families they meet. There is also a big difference between municipalities and their reasoning on what a reasonable standard of living is for a financial vulnerable family and how they work with preventing child poverty.

The Internet has become an important communicational medium that involves the majority of the world?s population. One group in particular that uses the Internet is the youth. This in turn makes the Internet a viable source for groomers to exploit, where groomers are what you call grown men and women that have the intention to contact youths for sexual purposes, the process is called grooming. In Sweden, a law has been made available to criminalize this particular activity, but it should not replace the prevention.

The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.

Specialiteten intensivvård utvecklades på 1950-talet, ända sedan dess har det varit känt att vissa av patinterna utvecklar akut förvirring eller psykiska störningar som senare kom att benämnas IVA syndromet. IVA syndromet orsakas av en process som startar vid insjuknandet/olyckan och beror på ett samspel mellan en psykologisk process, kemisk påverkan och den miljöstress som uppkommer av intensivvårdsmiljön som patienten vårdas i. IVA Syndromet orsakar ökad morbiditet och mortalitet. Syftet med arbetet är att beskriva omvårdnadsproblem och vilka åtgärder sjuksköterskan kan vidta för att förebygga utvecklandet av IVA syndromet. Undersökningen har utförts som en litteraturstudie.

The aim of this study is to describe and analyse the knowledge of three of the treatment methods used in youth welfare and this is accomplished through a knowledge review. This study contains an analysis of three different treatment methods described in eleven different peer reviewed articles. The articles are all internationally published between the years 2006 to 2012 and they are all effectiveness evaluations. The articles deal with treatment methods concerning Motivational interviewing (MI), Aggression Replacement Training (ART) and Cognitive behavioural therapy (CBT) and these are three of the most common in youth welfare in Sweden. There is not much knowledge of Swedish conditions and that is why this study focuses on international research.

The purpose of my study is to contribute knowledge about how class teachers can work with students who are in mathematics difficulties.
