Korrelation i smärta & obehag vid två olika hamstring tester hos fotbollsspelare
Bakgrund: Det är viktigt att kliniskt kunna avgöra om idrottaren är tillräckligt rehabiliterad för att återgå till full träning och matchspel eftersom otillräcklig rehabilitering är den största riskfaktorn för återskada i hamstrings. Därför skulle ett test med enkel utrustning behöva komplettera den kliniska undersökningen.Syfte: Studiens syfte är att undersöka vilket samband som finns mellan genomförandet av Nordic hamstring strength test och Asklings hamstring test utifrån skattning av smärta och obehag i samband med testen. Huruvida deltagarnas tilltro till att prestera sitt yttersta i en 90 min fotbollsmatch påverkas efter testerna samt att beskriva obehag och smärta efter testerna för spelare som varit skadad eller inte under senaste sex månaderna.Metod: 22 fotbollsspelare fick skatta sin tilltro till sin egen förmåga att prestera sitt yttersta i en 90 min fotbollsmatch samt skatta obehag och smärta med VAS i samband med testerna. Hamstring Outcome Score användes för att få en helhetssyn av deltagarnas funktion och skadehistoria kring hamstring. Spearman?s rho och Wilcoxon?s teckenrang test användes för att analysera resultatet.Resultat: Korrelationen mellan Asklings hamstring test och Nordic hamstring strength test var moderat (0,4-0,6) dock signifikant på <0,05.
The Reading the Mind in the Eyes Test - Revised Version á la Andersson & Karlsson
Introduction: The Reading the Mind in the Eyes Test is a widely used test for measuring aspects of social cognition. The aim of the present study was to provide results from a group of typically developing Swedish children (age 9-12) and to compare these results with children and adults in other Swedish and English studies, as well as results from a group of children with Asperger syndrome. Method: A Swedish version of the child version of the test was completed by 83 controls and by six children with Asperger syndrome. Results were compared between the two groups and with data from other studies. Results: The children in the current study did not differ on scores compared to children in the same age group in other studies.
Motstånd till förändring
The aim of this study is to compare attitudes to change among innovation and economics students and teachers at one of the universities in Sweden.Data about students? and teachers? attitudes to change was gathered using a survey.Keeping in mind that knowledge can lower ones resistance this study is based on a hypothesis that individuals from the innovations program have a lower resistance to change. The study is also based on earlier research in regards to comparisons between students and teachers.The results of the study show that teachers have less resistance to change than students. Individuals in the innovation program are however less resistant to change than individuals in the economics program.One can discuss whether or not results of the study show that the hypothesis is correct.The difference between individuals in the economics- and the innovation program are statistically significant and has moderate effects in reality. The differences between teachers and students are statistically significant but only have a small effect.It is however a starting-point for future studies that will possibly explore the subject more profoundly..
Soliditetens betydelse för goodwillnedskrivning under ekonomiskt ansträngda perioder : En studie av den svenska finans- och industrisektorn 2008
Background: The international accounting standard regarding goodwill gives opportunities to several accounting procedure choices, as goodwill is a complex, intangible asset. The valuation of goodwill affects equity/asset ratio and income statement, which gives that the stakeholders? impression of the group?s financial statement is affected by the valuation of this asset. It has been pointed out that difficult economic times bring impairment loss to the fore. During financial crisis, equity/asset ratio may be significant as the economy of the groups is expected to be strained.Purpose: The purpose of this essay is to explain the appearance of the possible relationship between a group?s impairment loss for goodwill and their equity/asset ratio, during financial straits.

Förrotation till omrörare
The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.
Farmakogenomikens betydelse för individvariationen avseende biverkningar och resultat vid Paclitaxel behandling av hund
Purpose
The purpose of this study is to evaluate the treatment results and adverse drug effects for 14 dogs receiving a new paclitaxel preparat named Paccal vet. The evaluated dogs are chosen to enter a pharmacogenomical study. Therefore, this paper intends to give an introduction to pharmacogenomics. Finally this study also aims at finding the homologue genesequenses in dogs to seven genes that are important for metabolism of paclitaxel in humans.
Materials and metods
The dogs went through 2-4 cycles of paclitaxel treatment, they received a new water-soluble formula named Paccal vet, at dosages of 100-150mg/m2. Treatment results and adverse effects are listed for each dog in table 1.
Föräldrars upplevelser av att förlora ett barn i cancer
It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.
Anpassning av VOD-tjänster för breda barnmålgrupper : EN ANVÄNDBARHETSUTVÄRDERING AV BARNPLAY UTIFRÅN MÅLGRUPPEN 3-11 ÅR
This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.
"Ja, det här blev ju snyggt!"
Most major companies today have a visual identity. It answers questions like: which font do I use? and when can I use the logo or not? Westinghouse Nuclear Fuel in Västerås have a visual identity but no guidelines for the employees to follow. Further-more, rollups and rollup handouts produced by Westinghouse are not mentioned in the visual identity. ?erefore the external information from Westinghouse is someti-mes, both by employees and customers, perceived as not uniform.
Utveckling av ett svensk-engelskt lexikon inom tåg- och transportdomänen
This paper describes the process of building a machine translation lexicon for use in the train and transport domain with the machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.

Impairment test av goodwill : Användning av diskonteringsräntan
Bakgrund: Efter införandet av IFRS har det förekommit en del förändringar gentemot tidigare redovisnings regler i Sverige. Från och med 1 januari år 2005 skall alla börsbolag gå över till IFRS 3 Business Combinations. Detta innebär att goodwill inte får skrivas av så som det gjorts tidigare. Nu mer måste det årligen ske ett Impairment test av goodwill för att undersöka om det föreligger ett nedskrivningsbehov.Diskonteringsräntan används vid impairment test av goodwill och är en viktig faktor vid nuvärdesberäkningar av kassaflöden.Problem: Noterade börsbolag utför ett impairment test av goodwill, vilket görs för att undersöka om nedskrivning av goodwill är aktuellt eller inte. Diskonteringsräntan är en viktig faktor vid Impairment test.
En skola för alla : Är denna skola integrerande eller segregerande för barn i behov av särskilt stöd
In this paper integration and inclusion were analysed in both theory and practice to see what they mean for pupils who reqire special support or pupils who have Swedish as a second language in compulsory school. The purpose of this work was to investigate whether inclusion is the best way of reaching the goal of a school for all children. A literary study, was conducted to test this hypothesis. The literature used for this purpose includes non-fiction books, handbooks, newspaper articles, declarations, conventions, and learning and course plans. Qualitative interwiews were held whit a remedial teacher, a Swedish-as-a-second-language teacher, and a class teacher who contributed greatly to this work thoough their experiences and vast knowledge.
