Analys av mellanspänningsnätet i centrala delar av Västerås stad
The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.
Evaluation of a behaviour protocol for use in recording the behaviour of horses following administration of methadone
There is a need for correct and adequate pain assessment in horses. Methadone is used in pain management in horses but the full pharmacokinetic picture of methadone is not yet known. The aim of this pilot study was to develop a behaviour protocol and suggest a reliable recording method for use in a larger research project with an aim to potentially correlate behaviours to concentration of methadone in blood. In this study two coldblooded trotters were given methadone intravenously with doses of 0.1 mg/kg for horse 1 and 0.2 mg/kg for horse 2. The horses were videotaped pre and post methadone administration.
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.
Otrogen läsning : Debatter om feminina publiker 1808-1815
Gendered reading has a history of intense debate and negotiation. In this essay I will examine how feminine and masculine reading was construed in the early 19th century through three Swedish texts that all give a didactic, moral and instructive opinion about gendered reading. They consist of an advice manual, a collection of letters and a periodical featuring an assortment of suitable reading material, all published between the years of 1808-1815 and directed to a female audience. As the male sex was generally considered the invisible, desirable norm and the female sex tended to be viewed as deviant and problematic, gendered discussions are inclined to focus on the latter. I will argue that female reading is largely construed in relation to the bourgeois marriage while the male is construed in terms of citizenship.

Automatisk testning av WebGL på mobil- och desktopenheter
WebGL is a standard for drawing graphics in a web browser. Currently it isn?t widely understood how consistently WebGL performs across a majority of the de- vices that support it. Determining if an image looks correct to a human observer is an interesting problem. The solution for this is useful when developing WebGL applications, since a developer could make better informed decisions during de- velopment.
Venture Capital & Banklån : Småföretagsfinansiering
There are many different forms of financing for small businesses and two common financing options mentioned in the study, bank loans and Venture Capital.Venture Capital is a form of risk capital financing, investing in unlisted stock market. The feature of the arrangement is that those people are trying to find companies that can offer unique, attractive and in demand products on a strong growing market. Since VC-firms are taking a big risk in cooperation with the investment, the VC-company strong demands while assessments are made on the company will generate a return in the future.Bank loans are the most common form of financing for companies in the market. Requirements and assessment under the law is hard especially for small businesses because financing entails high risks. Banks require that the liquidity management in the enterprise should be stable because the bank's main objective is to repayment of debt and the interest payable on the capital.The purpose of this study is to examine the requirements and assessments VC-firms and banks make use of the financing of small businesses. .
Testbänk för motorbåtsdrev
Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.
Igloo
This degree project has been performed along with Classic Garden in Gothenburg andBallongfirman Far & Flyg in Stockholm. Together we have developed a sun- wind- andrain protection. The protection is permanently assembled and mainly intended for publicenvironments as restaurants and outdoor cafés.The design on the sun protection was already done so our task has been to develop theconstruction and to build a prototype in scale 1:4 and one in scale 1:1. The look of thesun protection is approximately as the name implies, equal an igloo. The lamellae aregoing to fold out in different steps all the way down to the ground and the both sides willbe independently of each other.The first stage in the project was to develop differently principle proposal on how thefunction will work when folding in and out the protection.
Preoperativ SWAL-QOL och sväljningsfunktion hos Parkinson patienter selekterade till Deep Brain Stimulation
AbstractObjectivePatients with Parkinson?s disease often have symptoms of dysphagia. These swallowingproblems have consequences for quality of life as well for the physical wellbeing of thepatients. AimThe aim of this study was to describe and correlate Swallowing Quality of Life (SWAL-QOL)scores, self-assessment of swallowing function using a visual analogue scale and the resultsfrom a fiber endoscopic evaluation of swallowing function in patients who had been selectedfor Deep Brain Stimulation in caudal zona incerta. A secondary aim was to correlate diseaseduration with results from SWAL-QOL and the fiber endoscopic evaluation of swallowingfunction.MethodTen male Parkinson?s patients (age 45-69 yrs, median 61.5 yrs) who were selected for DeepBrain Stimulation completing the Swallowing Quality of life form, as well as rating theirswallowing function using a visual analogue scale and undergoing a fiber endoscopicevaluation of their swallowing function. ResultsThe median total SWAL-QOL score was 94% while the mean was 91%.
Vinstvarningars påverkan på företag i Large och Small Cap? :
Den här studien undersöker hur vinstvarningar påverkar stora och små företag. För att förklara dess påverkan på företagen har den effektiva marknadshypotesen och behavioral finance använts som grund. Avgränsningen har gjorts till Stockholmsbörsen då inga tidigare studier haft fokus på den. Empirin visar att företag i Large Cap påverkas med i snitt -4,63% och företagen i Small Cap med -8,42%. Large Cap visade signifikanta abnorma avkastningar under eventdatumet och dagen efter medan Small Cap endast visade signifikans under eventdatumet.
Inhalationssedering på CIVA : en retrospektiv beskrivning
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.
Ta rygg på insiders? : En studie om möjligheten till abnormal avkastning genom replikering av insiders köp & säljtransaktioner
Ända sedan handeln med finansiella instrument utvecklades under början av 1900-talet har problematiken kring insiderhandel existerat. Denna problematik bottnar i att personer med ett informationsövertag, dvs. insiders kan enligt vissa tidigare utförda studier generera abnormala avkastningar vid exempelvis aktiehandel. Oenigheten på detta forskningsområde är relativt stort. Det skulle därför vara intressant att titta på möjligheterna till abnormal avkastning genom att replikera insiders köp- och sälj transaktioner på den svenska aktiemarknaden.Denna studies frågeställning formuleras således; Kan utomstående investerare generera abnormal avkastning genom att replikera insiders köp- respektive sälj transaktioner på Stockholmsbörsens Small Cap lista?För att svara på denna frågeställning genomfördes en kvantitativ studie innehållande 60 stycken bolag noterade på Stockholmsbörsens Small Cap lista.
Följ upp målarbetet hellre än målen
Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.
