The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

Value at Risk (VaR) är en finansiell metod för att skatta risker och som används i stor utsträckning av banker och företag. VaR beräknar att en eventuell förlust inte skall överstiga ett visst belopp med 95/99 procents konfidens. Denna uppsats syfte är att undersöka om VaR kan appliceras på en svensk aktie när Riskmetrics-modellen (IGARCH) skattar volatiliteten på aktien trots oro på den finansiella marknaden. Undersökningen genomfördes på Volvos B-aktie med data från perioden 2003-01-01 till 201 2-12-31. Vi genererade enstegsprognoser över den potentiella förlusten (VaR) givet en fiktiv investering av 10 000 000 SEK.

Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.

Our companion animals can, with or without symptoms, carry infectious agents which have a potential to induce diseases in man, so called zoonoses. An immune compromised person has an increased risk of becoming infected by various agents, and thus also has an increased risk to become infected by one?s own companion animals. A study was carried out within the veterinary program at SLU, Sweden, based on a questionnaire answered by 31 physicians, 31 veterinarians and interviews of 30 immune compromised persons in Sweden. The study investigated the following questions: Which zoonoses do physicians and veterinarians consider to be the most important to inform immunecompromised persons about? How are immunecompromised persons being informed by their physicians about the risk of catching zoonoses from their companion animals? How are the owners of zoonosis-infected animals being informed by their veterinarians about zoonoses? Does veterinary medicine and human medicine communicate about zoonoses, in order to take the best care of immunecompromised persons in contact with animals? The results of our study imply that: - Physicians and veterinarians differ about which zoonoses immunecompromised persons should be informed about. - Only oral information is passed to immunecompromised persons and animal owners.

The purpose of this thesis is to investigate the ways in which emotion regulation and mood affects risk taking when it comes to decision making competence. Emotion regulation is an essential part of the attachment process, the development of an autonomous self and functional stress coping systems. Research indicates that there is a relation between a distorted emotion regulation and some psychological disorders like depression, PTSD, anxiety disorders and borderline (or instable emotional personality disorder). There is a definite need to analyze the relation between emotion regulation and decision making competence since it is relatively unexplored. A digital questionnaire was distributed amongst the participants.

The porpuse of this paper is to find out how three teachers working in years four to six in a Swedish school say they use formative assessment and how they use it in educational practice, and if there is a difference in the use of formative assessment between year four, five and six. Formative assessment is the kind of assessment that aims to enhance the student?s learning, as opposed to summative assessment wich is intended only to summarize student?s accomplishments. To answer the purpose, I conducted qualitative interviews with the teachers, and observations in each of the teachers? classrooms.

Bakgrund: Studier visar att ungefär var fjärde patient som vårdas på sjukhus har riskför att utveckla undernäring. Komplikationer av undernäring orsakar lidande förindividen samt förlänger vårdtiden vilket leder till ökade kostnader för vården.Problematiken med undernäring väntas öka då antalet äldre i samhället ökar. Äldre är enutsatt grupp där risk för undernäring, ätproblem och sömnlöshet är vanligtförekommande. Frågan är om risk för undernäring och ätproblem är vanligare hos äldresom lider av sömnbrist. Syftet: Var att undersöka om det finns ett samband mellansömnlöshet och risk för undernäring samt mellan sömnlöshet och ätproblem hos äldrepatienter.

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

The theme in this report has been how to benefit experience from accident investigations. The demand on the municipality to perform accidet investigations is relatively new, and maybe they aren?t clear what the demands means. This causes that there might be a problem to benefit experience from accident investigations, for improving the overall safety in the municipality. The main purpose of this report has been to clarify how experience from accident investigations, can be of benefit to society on a local level.

Operationell risk inom banksektorn är ett område under utveckling. Utredningen har behandlat ett ramverk för hantering av operationell risk kallat A Systemic Approach Framework for Operational Risk (SAFOR). Syftet har varit att konkretisera detta ramverk och inom detta utvärdera en metod kallad Damage Evaluation and Effective Prevention (DEEP-metoden) i kombination med ett datoriserat beslutsverktyg benämnt DecideIT. SAFOR hanterar operationell risk som är nära kopplat till företagets processer, personer och system. Dess utformning grundar sig i general system theory, en holistisk verksamhetssyn som minskar risken för överlappning mellan olika riskhanteringsområden.

Bakgrund och problem: För att öka stabiliteten i det finansiella systemet utvecklades ettinternationellt regelverk för kapitaltäckning, Basel I. Regelverket innebar att banker skullehålla ett visst minimikapital för att skydda sig mot risker. Det visade sig dock att regelverketinte gav ett fullständigt skydd mot risk, vilket ledde fram till ett reviderat regelverk, Basel 2.Operativa risker har blivit allt vanligare på senare år bland annat tillföljd av globaliseringen.Det nya regelverket innebär att operativ risk liksom kreditrisk och marknadsrisk har blivit enegen riskkategori. De metoder som används för att kvantifiera operativ risk är fortfarande iinledningsfasen. Detta ihop med att det är en svår gränsdragning av begreppet operativ risk tillandra risker, gör det till ett relevant område att studera.

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

Deltagarna i studien utgjordes av 341 personer från en kommun i Mellansverige.Resultatet visade att 41,9 % hade risk för eller var undernärda enligt MNA-SF. BMI <22poäng hade 23,5 %.

This essay examines how high school teachers in physical education and health thinks about assessment and grading. The essay show how teachers assess pupils during lessons and how teachers grade their students. The survey was based on interviews, in which six different teachers answered questions on the topic of assessment and grading. The issues surrounding assessment was linked to the theoretical concepts of formative and summative assessment, to see if the assessment methods teachers use. The issues surrounding grading was related to the theoretical concepts of validity and reliability in order to see how similar the grading is.The essay provides a picture of how the assessment and rate again looks different teachers.

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.
