There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

This study's main objective was to identify adolescents participation in alternative sport activities and which kind of physical activity that was preferred by adolescents who didn't had any earlier experience of sport clubs. The study combined interviews and surveys with the purpose to get both adolescents and sport leaders perspective. A total of five interviews were performed and fifty-four surveys was collected. The results showed that adolescents already physical active were those who participated in alternative sport activities. Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..

This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

The horse is an animal that often becomes humanized. Despite domestication, the horse still has a need to interact with other horses, be able to move for the most of the day, and being able to graze. If these needs cannot be fulfilled, the horse can be negatively affected and develop abnormal behaviours. An example of abnormal behaviours is weaving; the horse performs a swinging motion in the front area of the body during a long time. This literature review aims to investigate how different stabling forms (box/stall) affect the incidence of weaving, and also how this behaviour can be prevented or limited.

This is a study where the purpose was to investigate whether preschool teachers have a positive or negative attitude to outdoor education. Their view of outdoors education is also treated. The methods used were questionnaires and semi-structured interviews. The survey was sent to all preschool teachers in three municipalities and on a social network. The interviews were conducted at a preschool, which had a form of outdoor profile.

This thesis is a study over changes and similarities of people's activities in Berzelii park, with focus on the second half of the 19th century and present time. As one of the oldest public parks in Stockholm, Berzelii park has been a place for outdoor activity for more than a hundred years. During that time both the park and the society have undergone changes, but people are still using this green area in the city centre in a similar way as generations before have done. It is still a place for social gathering and during the summer month the park invite for optional and social activities such as a pause in the sun and pic-nic with friends. Some customs has disappeared like the 19th century social stroll, but through small changes in rules or design others have become given, like using the lawns as seating..

I detta examensarbete studeras en ny konstruktion av en reversibel axialfläkt. Genom experimentella tester utvärderas olika utföranden av fläkthjul. De faktorer som varierar är utformning på nav och skovelbas samt skovelvinkel. Alla tester genomförs i AB Akron-maskiners testrigg som är upprättad efter ISO 5801.Navets utformning visar sig inte ha märkbar påverkan på prestandan. Förändringar i prestandan upptäcks när olika kombinationer av nav och skovelbas testas.

Patientövervakning och rondmöten är centrala aktiviteter i all sjukvård. Teknik som tagits fram för patientövervakning och rondmöten är relativt underutvecklad vad gäller överblick och mötesstöd. En fallstudie genomfördes med två observationer och en fokusgruppintervju på intensivvårdskliniken vid Linköpings universitetssjukhus. Syftet med fallstudien var att ta fram grundläggande informationskrav för att stödja sjukvårdspersonal vid möten och ronder i en intensivvårdssituation. Målet var att utveckla en övergripande design för ett digitalt arbetsbord.

This field study examined how elderly and cognitively disabled people used and experienced a social companion robot. The following pages explores the questions: Which are the physical, social and affective qualities during the interaction? The aim was to through observations see how qualities of interaction could activate different forms of behavior. The results show that motion, sound and the eyes together created communicative and emotional changes for users who felt joy and were willing to share the activity with others. The robot stimulated to some extent users to create their own imaginative experiences but often failed to involve user or group for a long time and was also considered too large and heavy to handle..

Aim: The study aims to investigate the distribution of grades between students in a practical subject and in a theoretical subject.The problem:What is the grade distribution in physical education and mathematics, with respect to gender, socioeconomic background, parental education, ethnicity, and physical activity?Method:To answer the aim of the study a quantitative method was chosen. As the collection method used was questionnaires to 620 students in the 9th grade in Stockholm. Of the 620 questionnaires, 597 questionnaires were used for the static analysis. The method of analysis used cross tables and logistic regression analysis.

The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student?s being socially active offline, tend to use the media to a greater extent than those less active..

Inom vårdområdet hanteras en stor mängd känslig information och den bör finnas tillgänglig utan organisatoriska hinder. Många vårdanställda får snabbare och enklare tillgång till information genom informationsteknik (IT), men IT ställer även nya krav på medvetandet om informationssäkerhet.Den i detta arbete studerade litteraturen menar att användarna är den största orsaken till att brister uppkommer i informationssäkerheten. Det kan bland annat förebyggas genom upprättande av informationssäkerhetspolicy samt genom att ge information till och utbilda användaren vid införande av informationssystem.Syftet med arbetet var att fastställa hur användare av datorjournaler påverkas av kraven på informationssäkerhet och hur användarna påverkar informationssäkerheten. Vidare var syftet att ta reda på om de rekommendationer som Datainspektionen gett ut efterföljs av användarna. Observationer och intervjuer med vårdpersonal har legat till grund för att uppnå arbetets resultat.

Background The Shetland Sheepdog is a popular breed of dogs in Sweden. The breed is mostly used as a companion dog and is also popular within certain dog sports such as agility. The Shetland Sheepdog is not included in any breeding programs regarding joint health. The animal insurance company, Agria had recently informed the Swedish Shetland Sheepdog Club (SSSK) that they had noted an increasing number of arthritis in the elbow joints, therefore they wanted to exclude elbow joints from the insurance until SSSK started a breeding program against elbow dysplasia. After the start of this study Agria withdrew their demand, but the study went on as planned. Aims of this study The aims of this study was to investigate if there is any data that may show if there is a larger or smaller reason than before to suspect that the breed has a problem with elbow dysplasia and therefore would benefit from a breeding program regarding this.
