Bakgrund: Tidigare studier har visat att barn har sämre styrka i överkropp och bål samt är mindre fysiskt aktiva nu än tidigare, detta skulle kunna medför en ökad hälsorisk framförallt på längre sikt.Syfte: Att undersöka om ett pass med 4 min Tabata intervaller med stabiliserade övningar, varje skoldag under en 6 veckors period gav någon skillnad på de fysiska testerna och gav en ökad stabilitet och styrka hos barn i åldern 7-9 år.Design: Studien genomfördes som en interventionsstudie med en kvantitativ ansats.Metod: 42 barn varav 23 flickor och 19 pojkar i åldern 7-9 år deltog i studien som genomfördes på skoltid i klassrummen. Utöver studiegruppen användes 13 barn som kontrollgrupp de genomförde enbart de fysiska testerna före och efter studien.Resultat: En signifikant ökning av antalet push-up (P<0.05) och push-up (knä)(P<0.05) kunde påvisas efter studien.Konklusion: De fysiska tester som visade signifikanta förbättringar hade liknande övningar inkluderade i Tabatastudien..

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

?Facebook has become as natural as having a phone? The use of social media in three libraries in the Umeå region ? an evaluationSocial media has come to be an integral part of people?s everyday life, as well as the business world in terms of communication and marketing. More and more libraries also embark in the use of social media, and the purpose of this study is to evaluate the use of social media in three libraries in the Umeå region. The libraries all use Facebook as their current, primary social media. Thus this study focuses partly on the analysis of the content on each library?s Facebook page, and partly on the experiences of the responsible librarians. The evaluation is based on a mix of existing tools in evaluating social media that are relevant in a library context.

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

The purpose with the examination is to examine a preschool head and three teachers experiences and opinions of whether the tablet can be used to support childrens linguistic development and social interactions in preschool. To answer the purpose we will use these questions of issue:What is the purpose with tablets and how are they used in preschool activity?What pros and cons do the teachers see with tablets?How do the teachers resonate about the use of tablets to develop childrens language skill and social interactions?What type of social interaction occurs when children use the tablet?We have used interviews and observations as our methods. We interviewed three teachers and one preschool head in the capital city of Sweden. They all have a positive attitude towards the use of tablets in preschool.

The aim of this study is to investigate teachers? experiences of working with Writing to Read (WTR), and their perceptions of how pupils develop in reading and writing when they write on computers or similar devices. Another aim is to study teachers? motives for using the WTR method. The material used for analysis is four interviews with teachers who use WTR.

Studier som berör ämnet hur fysisk aktivitet påverkar det psykiska välbefinnandet hos äldre är något som berör alla. Fysisk aktivitet har i tidigare forskning visat sig påverka båda den fysiska och psykiska hälsan positivt. Mycket forskning är gjord på området, dock är de äldre underrepresenterade som målgrupp inom området. Syftet med denna studie var att undersöka i vilken utsträckning fysisk aktivitet påverkar det psykiska välbefinnandet, med inriktning självkänsla och fysisk självuppfattning, hos äldre. Undersökningen innefattade en experimentell undersökningsmetod med en randominiserad, kontrollerad design.

Motivation is a key factor in sustaining a healthy and active lifestyle, and technology has afforded us new methods for attaining information concerning exercise and health. This paper aims to examine how social media can motivate individuals to obtain and maintain an active and healthy lifestyle, as well as identify which particular social media channels are preferred for this purpose. Both quantitative and qualitative methods were used as data collection in this research. The results of this report show that images and text shared on social media, as well as the communication therein, can function as motivation for individuals to commence and maintain a regular physical activity and health regimen. Additionally, an individual?s sharing of their own training and health routine is enough to motivate the person in question to sustain their training and health procedure.

Detta projekt är ett examensarbete för kandidatexamen som är obligatorisk för alla studenter. För att ta ut examen måste jag lämna en skriftlig rapport om vad jag har gjort. Redovisa simuleringar och mätningar på olika kretsar. I mitt fall var jag intresserad på att studera hur varvtalet på en likströmsmotor kan regleras med hjälp av olika metoder.  Detta är mycket utmanande för mig eftersom jag inte har sett så många lösningar på detta problem. Jag kommer att använda kunskap, teknik och komponenter från Kraftelektronik för att utföra mitt arbete. Det blir mycket intressant att med dagens utveckling av tekniken se hur olika metoder kan användas för att undersöka hur kraftelektronik kan användas i kontroll av varvtal, frekvens och rotationsriktning av elektriska maskiner. .

The aim of this master?s thesis is to explore what learning potentials there are in Demoteket. Demoteket is an on-going project that preserves and exhibits young people?s artistic creations. The idea is that public libraries receives and lends out the young people?s artistic creations.

The purpose of this investigation is to study how librarians experience bookcrossing. We focused on the two following questions: Which variations are there in librarians conceptions of bookcrossing as literature exchange and reading support activity? Which variations are there in librarians conceptions of bookcrossing compared to other methods of literature exchange and reading support? Bookcrossing is an international book club where you share your books by leaving them at public places. The thesis is focused on librarians? conceptions and not the conceptions of members of bookcrossing.

Thesis purpose: The main purpose of this study is to empirically verify the applicability of Kozinets´ model on an interest, activity or lifestyle based online community, in order to develop an adaptive segmentation approach for segmenting online communities. Methodology: This research is deductive by nature, cross-sectional by design and undertakes a quantitative approach using self-completion questionnaire as a part of a web survey to collect the empirical data needed. Theoretical perspective: The main theories guiding our work and supporting the findings of this study include: market segmentation (descriptive and behavioural) and communities (consumer communities and online communities). Empirical data: A web survey with self-completion questionnaire used to gather empirical data from members of interest, activity or lifestyle based online communities. Conclusions: This study took the specific characteristics of online communities into more consideration than previous research and literature has done and also recognized that an adaptive segmentation approach is needed, depending on the communities of study.

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

Sexuality contains more than just reproduction and is an important part of quality of life. Chronic disease can lead to sexual dysfunction for both males and females. The nurse plays an important role in informing and teaching. Throughout dialogue and observations the nurse can detect possible problems, document and then take measures. The study was performed as information retrieval of literature where the cause was to highlight sexuality for patients that have experienced a myocardial infarction.
