Reliabilitetstest på balanstesterna Unilateral stance och Limits of stability

Människans balanssinne är ett av våra viktigaste sinnen som dagligen sätts på stora prov då vi som tvåbenta individer ska upprätthålla kroppen i normal position vid rörelser och aktiviteter. Människans balans bygger på tre olika sensoriska system som arbetar i synergi för att upprätthålla kroppen i en bra position. Balance Master är ett mätinstrument för att mäta människans posturala kontroll. Syfte: Studiens syfte var att undersöka reliabiliteten i balanstesterna Unilateral stance och Limits of stability utförda på en Neurocom balance master över bestämd tid på friska individer. Material/metod: 11 friska försökspersoner mellan 23 och 29 år utförde balanstesterna Limits of stability och Unilateral stance vid fyra olika testtillfällen.

Test-retest reliabiliteten i balanstesterna Unilateral stance, Limits of stability och Rhythmic weight shift

Människans balanssystem kan beskrivas utifrån tre delkomponenter, det vestibulära, det visuella och det somatosensoriska systemet. En rad olika skador och sjukdomar som påverkar dessa system stör därmed också balansen. Balansstörningar kan verifieras med hjälp av funktionella tester eller teknisk utrustning. Då teknisk utrustning används är det vanligt att instrument utnyttjas med kraftplattor i syfte att mäta det posturala svajet hos patienterna. Vid balansutvärdering är det viktigt att de instrument som används är validitets och reliabilitetstestade.

Revision av gränsvärdena - En studie om hur svenska revisions- och redovisningsbyråer skulle påverkas av tillämpning av EU-direktivens maximala gränsvärden för revisionsundantag

Background: Currently Sweden has the possibility to like other EU countries raise the limits of statutory audit, but have chosen significantly lower limits. The reform was adopted in 2010 and only applies to smaller companies and there is great pressure for the limits to rise in future. This would enable Swedish companies to compete on equal terms in Europe. Aim: The aim of our study is to investigate the impact of the removal of the statutory audit for smaller companies from audit and accounting bureaus perspective and also the possible impact if the limits were to rise. Furthermore we want to explore how the supplies of other financial services have developed as a result of this.

Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

På uppdrag av Allah - En studie av legitimiteten i den saudiarabiska statsapparaten

Since 2003 Saudi Arabia is under attack from domestic Al Qaida-cells which, by random shootings of westerners and bombings of compounds and official state buildings, is trying to challenge the stability of the royal regime. According to Al Qaida, the Royal family is attacked because of their friendly relations to the US and for not implementing Islam in the Saudi society as profound as they ought to. Political analyst finds it obvious that the Islamic Al Qaida-cells by terrorism is trying to erode the stability in the kingdom.An important foundation for stability for any government is legitimacy. The aim of this thesis is to examine the royal legitimacy strategy in the state bureaucracy of Saudi Arabia. The question at issue is: how has the royal family constructed the civil, military and religious bureaucracies to maintain and promote stability and legitimacy?The thesis focuses on the on three different units within these three bureaucracies and it surveys the way they are staffed and organized to strengthen and maintain legitimacy for the royal family.

Att ligga fint - en diskursanalys av sexualupplysning på internet utifrån ett queerteoretiskt perspektiv

This is a discourse analysis of three WebPages which topic is sexual information. Our purpose is to examine the WebPages RFSL (The Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights), RFSU (The Swedish Association for Sexuality Education) and UMO (Reception for young people) from a queer theoretical perspective and illustrate how they discuss the subjects? gender, sexual preference and sexual limits. Our questions are; what information about gender, sexual preference and sexual limits are presented on the WebPages RFSU, RFSL and UMO, and what similarities and differences can be identified and how can these be analyzed from a queer perspective? Our material was collected from the three WebPages and categorized according to three topics of interest; gender, sexual preference and sexual limits.

Järnets introduktion i Skandinavien : -I ett arkeologiskt perspektiv

The views on and the knowledge of the introduction of iron to Scandinavia have change by the history of archaeology. The results and discussions are put in the context of time and how that time is reflected in their work and texts. This limits that scholars put up to orientate themselves conceal the complex reality. The limits are changing all the time and is dependent of time and person..

Stabilitetsberäkningar och åtgärdsförslag vid islast på Skålandammen

Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.

Kommersiella Fastighetshyror och Finansiell Stabilitet

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

Uljabuouda vindkraftpark turbinmodellering och stabilitetsanalys

This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.

IT och HR varför så krångligt? : En kvalitativ undersökning av ett personaladministrationssystem i ett landsting

IT exist and are needed in larger organisations today, this creates possibilities for new applications. It has become more frequent with IT within HRM which has developed new concepts like e-HRM and HRIS which links IT and HRM together. We have through qualitative content analysis of interviews investigated how IT-tools affect HR-workmanship. The purpose is to create a basis for describing how employees experience their work with HR within a PA-system. The basis of the PA-system will then answer if it contributes or limits the employees and their activities.

Dammsäkerhetsanalys via stabilitetsberäkningar för Långströmmens kraftverk : En jämförelse mellan olika dimensioneringsmetoder

A detailed dam safety evaluation (in Sweden called FDU) was performed in 2009 by WSP where stability control was performed for Långströmmen power plant with associated spillways. This evaluation concluded that stability could not be ensured, and risk of sliding occurred. The evaluation is based entirely on the recommendations outlined in RIDAS, the power companies guidelines for dam safety, and it is clear that extensive renovations are necessary to stabilize the dam.In this work, the stability will also be checked with guidance through new proposals on guidelines for concrete dams sliding stability, ELFORSK?s report 08:59. This report considered the guidelines in RIDAS as oversimplified, both from an international perspective, but also with regard to the current state of knowledge regarding dam safety.

STABILITET I INSOMNI, ÅNGEST, DEPRESSION OCH UTBRÄNDHET OCH RELATIONERNA TILLSTÅNDEN EMELLAN

Mental illness is today the leading cause of long-term sick leave and insomnia, anxiety, depression and burnout are among the most common conditions. The aim of the study was to investigate the stability of these conditions and how this is influenced by gender and age, as well as the extent to which these states are risk factors for each other. The participants were a random sample (n = 2336) from the general population in the age of 18-79 years. The results showed that stable illness was more common among women than men, and that stable illness decreased with aging. The stability itself was not affected by gender or age. Relations between the conditions were bidirectional and they constitute major risk factors for each other (odds ratios, OK = 2.37 to 6.46). The largest risk factor for a condition is, however, previous occurrence of the same problem. Previous burnout was found to be a significantly larger risk factor for future burnout than previous insomnia for future insomnia (OK = 9.63 and 5.74, respectively). The results suggest that insomnia, anxiety, depression and burnout, despite their differences, are similar regarding symptoms and underlying causes. The importance of early interventions to prevent comorbid conditions which are more complicated and more difficult to treat is emphasized..

Betydelsen av gränssättning i relationer mellan föräldrar och ungdomar

The purpose with this study was to show the relations between parents and youths from an adult perspective. We wanted to examine in what way the individualized society, limits and psychic health and unhealthy with parents could affect their youths. We chose to make a qualitative inquiry about this subject and had implemented interviews with social welfare secretaries, recreation leader and night walkers. To receive a deeper insight participant observation with night walkers, participant in parent education and participant in three different recreation centres was carried out.Both writers were interested in relations and relations making between people, which led us in to the chose subject. We did not found any earlier research in the subject which made the investigation even more interesting.

Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.
