This study has emerged from a growing interest in students' sleeping habits. During practical training as teachers, we have noticed a discussion of students' sleeping habits, fatigue and student performance at school in relation to their sleeping habits. The purpose of this field survey was to examine students? sleeping habits and self-perceived performance ability in school in relation to sleeping habits. The material was collected from a questionnaire that was answered by 200 students in 4-6th grade and 188 students in 1-2th grade in the upper secondary school, this to give an opportunity to see if there were any differences between the different age groups.

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.

This study aimed to investigate written and oral narrative in adults. The participants consisted of 30 subjects aged 32-79 years. They produced one picture elicited and one free narrative, both written and orally. The written narratives were recorded in a keystroke logging program and the oral narratives were transcribed orthographically. Data from all the narratives were analyzed according to: number of words, words/minute, active writing time, total process time, number of characters and number of characters in the final text.

The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.

Falls and fallinjuries are very common in peoples own homes in various institutions. Hospital inpatients often fall during daytime in connection with their visit to the toilet. Visual impairment such as cataract, glaucoma, macular degeneration and diabetic retinopathy can cause falls. The purpose of this study was to examine patient´s records where falls and fallinjuries were documented at an emergency clinic and to examine if they were registered to visual impairment. The records from 68 hospital inpatients from the age of 65 years and older who did fall during the year of 2004, were examined.

Bakgrund: Patienter som ventilatorvårdas på intensivvårdsavdelning behöver ofta någon form av lätt sömn (sedering) för att tolerera endotrachealtuben och ventilatorbehandling. De traditionella intravenösa läkemedel som ges har lång halveringstid och det är stor risk för kvardröjande effekter. Syfte: Denna pilotstudie syftar till att studera sederingsdjupet enligt MAAS hos de patienter som blivit sederade med inhalationsgas, kontrollera vakenhetsgraden enligt GCS hos dessa patienter efter avslutad sedering, samt beskriva vilka patientgrupperna är som fått inhalationssedering. Metod: Journalgranskning där resultatet har analyserats och kategoriserats, därefter har en sambandsanalys gjorts. Resultat: I resultatet identifierades 3 patientkategorier som fått isofluransedering: patienter med hotad luftväg som förväntats behöva kort sederingstid och snabb väckning, patienter som var svåra att sedera optimalt med intravenös metod samt patienter med organsvikt där risk för ackumulation och/ eller förlängd elimination av läkemedel förelåg.

The purpose of this Bachelor Thesis is to investigate whether the introduction of IFRS, and in particular IAS 40 regarding fair value accounting of investment property, has lead to increased financial risk for Swedish real estate companies. Financial risk is measured using several financial risk ratios during the period 2000-2009, effectively covering the period before and after the introduction in 2005. The financial risk is found to actually have decreased significantly in comparison with the control group. The relative decrease supports the notion of a factor unique to the real estate companies at least partially driving the change, possibly IAS 40. However, this change is, due to the statistic method employed, only an indication of the direction of change, and consequently interpretations of the magnitude of change cannot be made.
