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.

According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.

Syftet med examensarbetet var att mot pedagogers praktiska erfarenheter och professionella praktik pröva olika teorier kring risk- och skyddsfaktorer vid utagerande och internaliserande beteendeproblem hos barn och unga samt beteendeproblemens koppling till läsförmåga för att se hur teorierna fungerar i relation till praktiken. Studien är kvalitativ och datainsamlingsmetoder har varit semistrukturerade intervjuer och kompletterande enkäter med sammanlagt tio informanter. Dataanalysen har inspirerats av en fenomenografisk metodansats i de första analysstegen. Resultatet visar bland annat att informanterna har erfarenheter och uppfattningar av att barns/elevers beteendeproblem dels kan handla om förmågor och färdigheter hos individen själv, exempelvis bristande kommunikativ förmåga eller svag självkänsla, dels att faktorer i hemmiljön och/eller förskolan/skolan verkar hindrande för barnets/elevens utveckling och lärande. Framför allt visar materialet att lärarens relation till barnet/eleven och föräldrarna har stor betydelse för utgången av beteendet.

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

The purpose of this master's thesis is to investigate how the students at Chalmers University of Technology at Lindholmen in Gothenburg use libraries in their schoolwork. The empirical material consists of the answers of questionnaires that were handed out to two classes of students, on the second year of their education. To illustrate the topic there are a theoretical frame and examples of earlier studies. The theoretical frame is Limbergs texts that deal with for example information seeking and how important it is in all education. The earlier studies are about student's different ways of using libraries.

Trycksår orsakar lidande för patienter och höga kostnader för sjukvården. För att förhindra uppkomst av trycksår är det viktigt att identifiera patienter med ökad risk för trycksår samt att aktivt arbeta med preventiva omvårdnadsåtgärder. Ett strukturerat arbetssätt kan göras utifrån kvalitetsregistret Senior Alerts rekommendationer. Senior Alert är inriktat på förebyggande vård av äldre över 65 år och i registret registreras bland annat risk för trycksår, planerade åtgärder samt sjuksköterskans utvärdering av de insatta åtgärderna. Syftet med studien var att kartlägga täckningsgrad, utförda riskbedömningar och planerade åtgärder avseende risk för trycksår i kvalitetsregistret Senior Alert.

Uppsatsen är en fallstudie om vad 18 ungdomar, som läser det sista året på det samhällsvetenskapliga programmet, har för framtidstro och framtidsdrömmar vad gäller studier och yrken de kommande tio åren. Studien avser att undersöka om det kulturella kapitalet påverkar ungdomarnas syn på framtiden vad gäller studier och yrken samt om det kulturella kapitalet påverkar vilka yrken som innesluts i ungdomarnas kognitiva karta. Eleverna har fått besvara enkätfrågor samt skriva två mindre uppsatsuppgifter. Undersökningen analyserar ungdomarnas skildringar kring deras framtidstro och framtidsdrömmar med hjälp av Pierre Bourdieus kulturella kapitalbegrepp samt Linda S Gottfredsons kognitiva karta över yrken. Resultatet visar en tendens att ungdomar med akademikerföräldrar har en kognitiv karta med mer prestigefyllda yrken inneslutna än vad de andra eleverna har.

Sahlgrenska Academy at University of GothenburgDepartment of Clinical NutritionAbstractTitle: The effect of nutritional treatment on functional recovery after stroke, a systematic reviewAuthor: Ingrid Blankenau and Amanda LindbladSupervisor: AnneMarie GrönbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTS Type of paper: Examination paper, 15 hpDate: April 13, 2011Background: Every year 30 000 people in Sweden suffer from stroke. This costs society about twelve billion SEK. Many stroke survivors experience functional impairment which may lead to difficulties for them to meet their nutritional needs. Nutritional treatment is important in the recovery process after stroke as malnutrition increases the risk of complications.Objective: To investigate the possible effect of nutritional treatment on functional recovery after stroke.Search strategy: The search was conducted in the databases PubMed, Scopus and Cochrane by using the English keywords stroke, nutrition, rehabilitation, functional outcome, recovery, acute stroke, ischemic stroke, ischemic acute stroke, nutrition therapy, brain hemorrhage, functional recovery and nutritional rehabilitation.Selection criteria: Studies published before 2001 conducted on human subjects who suffer from stroke where they measured functional capacity and did a nutritional intervention, written in English, Swedish or Norwegian, and did not have to be requested from the library.Data collection and analysis: A systematic search was performed in PubMed. Studies which had an interesting heading were examined and abstract read.

The main purpose of this Master?s thesis is to investigate how the transfer from academic studies into professional life is experienced in retrospect by professional librarians. The aim is also to examine in which context the studies in library- and information science in Sweden has been formed. To attain the purpose of the thesis four main questions is being asked: In which context has LIS-studies from the period 1993-2007 been formed? Which competence does the professional librarian consider to be the most fundamental in professional life? Does the professional librarian experience that the knowledge attained from LIS-studies is sufficient for the actual tasks? Which are the differences between tasks at different types of libraries? The study is performed through a questionnaire survey in which 94 professional librarians express their experiences of their LIS-studies in retrospect.

Praktiskt arbete inom institution innebär kontinuerliga riskbedömningar och beslutsfattande av eventuella åtgärder. Denna studie syftar till att undersöka vilka uppfattningar och resonemang personal vid två särskilda ungdomshem har kring risker och riskbedömning samt vilka beslutsstrategier som tillämpas. Vidare undersöks skillnader i bedömning ur ett genusperspektiv. Kvalitativ metod tillämpas och studien omfattar tolv intervjuer. Resultaten visar att risk och riskbedömning uppfattas som mångdimensionella begrepp omfattandes samtliga aspekter i det dagliga arbetet, dock förekommer interindividuella skillnader utifrån kunskap, erfarenhet och personlighet.

Introduction: Anxiety and depression are common among patients enrolled in psychiatric outpatient care. Ear Acupuncture is an alternative form of treatment that has been shown to relieve anxiety and depression in previous studies.Aim: To evaluate ear acupuncture as a group treatment for depression and anxietyMethod: A psychiatric outpatient clinic has been offering group treatments with ear acupuncture for anxiety and depression for 5 weeks. Participants of the study have answered self-rating scales Montgomery Åsberg Depression Rating Scale, Beck Anxiety Inventory and Sheehan Disability scale before and after the treatment period. Material was collected in the period 2008-2012 and has been analyzed in SPSS.Results: Data from 31 patients were included in the study. The results from the study showed a significant difference, between the measurements before and after treatment, with a reduction of the average values in the three different scales.Summary: From this study, it is difficult to draw any conclusions about the effect of ear acupuncture.

Abstract- Stress, conformity, groups and self-worth in high-school girlsThe aim of this questionnaire-survey was to investigate the experience of stress and symptomsof stress in high-school girls, and to examine if the experienced symptoms of stress could bepredicted by groups, self-worth and conformity. Another purpose of this study was to describethe girls own thoughts concerning these factors. 80 girls between the ages of 15-18 yearsanswered the questionnaire. The results showed that stress could be predicted by theexperience of conformity, but not by the experience of belonging to a group and self-worth.The most common symptoms of stress were tiredness, problems to concentrate and headache.The girls reported that they thought that girls of their own age were ?slutty and cocky?, andthey thought that it was important to look good, but at the same time many girls were happyabout themselves and they had realised that they had to live with who they are.Keywords: high-scool girls, stress, groups, self-worth, conformity.

Vi har undersökt ålder och erfarenhets påverkan på revisorers risk- och väsentlighetsbedömning. Tidigare studier om risktagande och dess relation till ålder och erfarenhet har visat blandade resultat, somliga forskare menar att det finns en positiv korrelation medan andra menar det motsatta. Denna uppsats grundas på en casestudie som har utförts på åtta svenska revisorer. Åldersspannet bland revisorerna i studien är 24 till 67 år. Utifrån ett fiktivt företag har revisorerna tagit fram ett väsentlighetsbelopp, samt bedömt vilka riskområden som finns i resultat- och balansräkningen.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.
