Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

Höftledsdysplasi (HD) är en i raden av genetiska sjukdomar hos våra hundar Det är en ärftlig sjukdom som främst finns hos storvuxna raser och ger en felaktig utveckling av höftleden som ger upphov till förslitning av brosket i höftleden med benpålagringar som följd. Trots avelsprogram fortsätter höftledsdysplasin att vara den mest vanliga ortopediska sjukdomen hos våra hundar. Höftledsdysplasin karaktäriseras som överdriven slapphet i ledkapseln och dess ligament, samt att ledkulan inte är normalt placerad i leden. Dagens graderingssystem som används är inte tillräckligt för att kunna stoppa sjukdomens framfart. Därför utvecklas nu ett HD-index som inte bara tar hänsyn till individens egna HDstatus utan även dess släktingar. Det är inte bara genetiken som styr uttrycket av HD. Även miljöfaktorer har inverkan på om tillståndet uttrycks samt i vilken allvarlighetsgrad. Diet och motion har därför visat sig ha betydelse för sjukdomens utveckling.

Bakgrund: Enligt världshälsoorganisationen WHO har 347 miljoner människor diabetes runt om i världen. WHO menar att diabetes kommer vara den sjunde ledande orsaken till död år 2030. Diabetes typ 2 kan vara genetiskt betingad och den påverkas av livsstilsfaktorer såsom kost, motion, ålder och tobaksvanor. Vilket innebär att det är viktigt att diabetiker har kunskap och rätt tillvägagångssätt för att kunna hantera och utföra egenvårdsaktiviteter. Sjuksköterskans roll är att stödja och främja egenvården.

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Contemporary libraries face challenges in transforming their organization to meet the digitalized society. To develop the process of digitization of literature is a natural way for libraries to go when they already have more visitors online than physically. Since the demand for digital material is so sought after, we feel challenged to address the challenges of the Internet as an emerging functional medium for distributing knowledge. These developments will be able to significantly modify the nature of literature as well as the existing system of quality assurance. In this study, we explored and analyzed a digitization project at a research library.

The valuation of an asset is one of the most important thing with accounting, though one of the most difficult thing as well. However, in deciding useful service life for an intangible asset and property, plant and equipment, there are quite a margin for the companies, which creates a difference between companies and industries. When computing the value of the inventories there are a few possibilities available for the companies, which also can generate differencesbetween companies and industries. Although these differences can occur, there might be some similarities in the companies? estimates.

Abstract: Elite soccer in combination with education is a unique and demanding task. The path towards a glory career in sports takes hard mental and physical training. The objectives in this study are 6 elite focused high school students studying high school education programs in combination with football profile. They are 3 of each gender. The purpose of the study was to find out more about their perspective of motivation and what makes them keep going towards a career in football in beside their education.The study is of empiric hermeneutic survey used qualitative method and interviewing to collect data.

Diabetes typ 2 är i dag en av de största folksjukdomarna, och den fortsätter att öka successivt. Fetma, som oftast beror på dåliga matvanor och låg fysisk aktivitet, är en stor bidragande orsak till ökningen. När en person drabbas av diabetes innebär det att patienten bör ändra sin livssituation när det gäller kost och motion. Undervisning av sjuksköterska kan stödja patienten i denna omställning. Syftet med denna studie är att beskriva patienters erfarenheter av undervisning i diabetes typ 2.Datainsamlingen genomfördes genom sökning i databas Cinahl, Pubmed, och sökningar i andra artiklars referenser.

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

Den minskade fysiska aktiviteten bland barn och ungdomar håller på att få förödande konsekvenser för folkhälsan. Trots att kunskapen finns om hur viktig den fysiska aktiviteten är för den motoriska, sociala, psykiska och fysiska utvecklingen fortsätter andå statusen av ämnet Idrott och hälsa att vara låg. Syftet med denna studie var att beskriva gymnasielevers vanor avseende fysisk aktivitet samt analysera vad skolan kan göra för att förbättra hälsan hos eleverna. Metoden som användes var en enkätundersökning. Urvalsgruppen utgjordes av 65 elever, varav 41 flickor och 24 pojkar, i årskurs 2 på en gymnasieskola i Skåne.Resultatet visar att 74% av eleverna ägnar sig åt motion minst 3 ggr/vecka: Femtiofem procent tycke om att röra på sig och lika många var fysiskt aktiva som barn.Slutsatser som kan dras av detta är att många elever tycker om att röra på sig men för att alla ska bli nådda är skolan en viktig arena som borde ta sitt ansvar.

Detta examensarbete gick ut på att enligt utvecklingsprocessen på Motion Control utveckla en prototyp av en kabelersättare för en produkt på företaget; USB I/O. USB I/O är en mät- och styrenhet och datainsamlingsenhet för USB-porten med flera in- och utkanaler som i flera applikationer har som nackdel att den är kabelbunden. Tanken var att göra en enhet som man ansluter USB I/O till och som kan kommunicera direkt med konventionella ?Bluetooth-dongles? som är vanligt förekommande på konsumentmarknaden.Tre undersökningar gjordes. Den första var en marknadsundersökning för att se lämpliga systemkoncept samt vilka konkurrenter som kan finnas.
