Quantitative thermal perception thresholds, comparison between methods
Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).
Mental träning på schemat : Hör tankens kraft hemma i skolan?
AimThe aim with this study was to acquire knowledge of mental training and if you can use it in the elementary school to increase in a short period of time the performance in a coordination test. Furthermore we wanted to investigate teachers understanding of the possibilities to perform this kind of training in the elementary school, and if there is support for this in the school regulation.MethodAs method we have used a combination of a literature pre-study, interview and at the end an experiment. Before the experiment and interviews could take place we studied literature about mental training to get a basic knowledge of the subject. The facts we learned from our pre-study and interviews gave us the base for our experiment. The experiment group included 23 pupils in a third class at school situated in Stockholm.
Spridningen av COSO i de svenska kommunerna
Syftet med vår uppsats var att undersöka spridningen av COSO-modellen i de svenska kommunerna, och vilka som är idébärarna av modellen. Även korrelationen mellan implementering av modellen och kommuners politiska, geografiska och storleksmässiga placering belyses.Då undersökningen bedrivs inom kommunal kontext har studien en institutionell ansats, och teorierna som används för att kartlägga spridningen av modellen i kommunerna är NPM, Institutionell teori och Spridningsteori. Undersökningen genomfördes med en webbaserad enkätundersökning, och vår målpopulation var Sveriges kommuner. Svarsfrekvensen på undersökningen blev 68%.Empirin analyserades med hjälp av Mann- Whitney test och Chi- Square test, med en signifikansnivå på 5%. Vårt resultat visar att det finns ett samband mellan spridningen av COSO och kommuners invånarantal.
Ip-telefoni med Skype som ett alternativ till PSTN för privatanvändare
The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security.
Neuro Muskulär Elektrisk Stimulering (NMES) som behandlingsmetod hos strokepatienter med droppfot
Stroke är en av våra stora folksjukdomar. Cirka 30 000 personer insjuknar årligen i Sverige. Många av dessa personer får även droppfot. Peroneusstimulering började användas för första gången 1961. Tekniken är nu generellt känd som Funktionell Elektrisk Stimulering (FES).
Strategies for Goodwill Allocation
Since 2005 all companies listed on a regulated stock exchange within the European Union are required to present their financial reports in accordance with International Financial Reporting Standards (IFRS) and International Accounting Standards (IAS). The purposes of these standards are to accomplish international harmonization of accounting rules to make financial reports more comparable. However, recent research has shown that some firms tend to use goodwill strategically in a business combination by manipulating the acquired assets and consciously allocate the intangible assets to goodwill to reduce the depreciation in the income and decrease costs. This phenomenon may reduce the comparability between financial reports and thus has an opposite effect on the purpose of IFRS and IAS.The aim of this study is to show how the companies involved in this study allocate goodwill strategically. Furthermore, the introduction of the new standards has contributed to that goodwill now is a subject for impairment test, therefore we want to show whether this affected the comparability of the companies in this study.An empirical study was conducted, based on interviews with four Swedish managers.
Utveckling av erfarenhetsåterföring - I samarbete med AF Bygg Göteborg AB
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Kognitiv återhämtning efter generell anestesi
ABSTRACTBackground: After general anesthesia the cognitive ability is temporarily impaired. Cognitive recovery is necessary for the patient to be able to assimilate the information that she / he gets postoperatively. It also increases the patient safety. There are few methods to estimate and assess the patient's cognitive recovery before and after anesthesia. The purpose of this study is to test the usefulness of the instrument PQRS and to assess the patients cognitive recovery after anesthesia.
Jämförande av Genesis Single och kliniska test : Muskelstyrka hos individer med tidigare ACL-skada
Inom sjukgymnastiken används mätning av muskelstyrka för att utvärdera och planera rehabiliteringsperioder. Isokinetiska dynamometrar och one repetition maximum (1RM) är två vanliga metoder för att mäta muskelstyrka. Efter en skada på främre korsbandet (ACL) sker en muskelatrofi av bland annat mm. quadriceps och hamstringsmuskulaturen och det är därför viktigt att kunna utvärdera dessa muskler. Genesis Single är en ny tränings- och utvärderingsmaskin på vilken inga tidigare studier gjorts.
Förberedelser inför den väpnade striden : Två verktyg; Idrottspsykologi och samtal om döden
The combat mission is an extreme situation with high demands of the soldier. Killing might very well be necessary. Before a mission a soldier can experience stress due to these factors. The purpose of this paper is to find methods to handle stress due to an upcoming combat mission and to the prospect of having to kill. The main questions of this essay: -How can certain parts of the physiological psychology improve a soldiers ability to perform a mission? ? Is the Swedish soldier mentally prepared to kill? The theory for this essay has been described using litteratur by experts within the field, and the results thereafter discussed.
Optimal högtalarplacering i en lastbilshytt
This Degree Project was about finding the best loudspeaker placement in a heavyweight truck and also the best suited loudspeaker for this task. The project took place in Södertälje, Sweden, on behalf of Scania CV AB. The goal was to create a new listening environment in a truck cabinet.The results were accomplished by the performance of a few different tasks. First a benchmark was made on Scanias top competitors. Second a listening test was made to get an apprehension of what people find lacking in the sound reproduction of the sound system.
