At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

This thesis work has introduced process orientation at the printing company Color Print Sweden AB. The outcome ofthis work is a survey of the work flow at the prepress department. To visualise the production process at the companya comprehensive mapping of the main process, order-to-delivery, has been made. The work has detected a couple ofcritical elements in the existing process. These elements are the following: initial check of material delivered to the prepressdepartment as well as the control made of the plotter print-out, digital test print and plate.

Studies in Sweden have shown that about 80% of all youth in Sweden have participated in organized sport during their upbringing but at the age of 20 only 50% of these continue. There have been several attempts to understand why youth stop participating in sports but few aimed to understand why they continue. The objective of this study was to examine if there is a difference in motivation between youth (in the ages of 16-20 years) who participate in recreational and elite sports. The study was carried out as a quantitative survey where both recreational (n=35) and elite athletes (n=33) particpated. The study used a Sport Motivation Scale questionnaire translated into Swedish.

Since 1983 all Swedish companies are legally obliged to allow themselves to be audited. Recently the question of whether small companies should be subject to this or not has frequently been discussed. Many find it superfluous and think it ought to be abolished. In England small companies no longer have to be audited. However, in a study by Jill Collis it has been shown that a large number of companies choose to be audited although there is no obligation for them to do so.

Dagens utveckling av mjukvara går snabbare och snabbare samtidigt som mjukvaran blir allt mer komplex. Att under dessa omständigheter kunna bibehålla en lika om inte högre kodkvalité är en utmaning. På UIQ bestämde de sig för att undersöka om ett automatiserat unit test kunde hjälpa dem. Metoderna för att komma fram till resultaten i denna rapport har varit intervjuer, en enkät, intern information och litteratur så som forskningsartiklar m.m. Denna rapport är en utredning av automatiserade test, vad man bör tänka på, vilka fördelarna är, vilka testfall som är möjliga att automatisera med mera.

Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.

I denna studie undersöktes hur 291 individer som genomgått en Gastric Bypass för mer än två år sedan skattade sin psykosociala hälsa. Syftet med studien var att undersöka samband mellan den psykosociala hälsan och hur länge respondenterna hade varit opererade, eventuell viktuppgång samt hur länge i livet respondenterna haft obesitas. Mätinstrumenten som användes var Satisfaction With Life Scale (livstillfredsställelse), Social Physique Anxiety Scale (social kroppsångest) samt Rosenberg Self- Esteem Scale (självkänsla). Resultaten visade att ju längre tid det var sedan patienterna opererades samt ju mer patienterna ökade i vikt, desto lägre skattades den psykosociala hälsan. Vidare skattade de patienter som varit obesa hela livet, högre social kroppsångest jämfört med patienter som rapporterade att de haft perioder i livet som normalviktiga..

This bachelor thesis in Landscape Architecture is about the planning and design of public spaces in small towns in Sweden. My opinion is that the small towns often are overlooked and my determination is to see if that is right. The purpose with this thesis in Landscape Architecture, with focus on a durable society is to find the central public places in small towns and evaluate their function. This thesis has a focus on good design of central public spaces, designed for the inhabitants of the small towns. A small town, which is the focus of this thesis, is defined to have 200-2000 inhabitants. The small towns, which often are built around industries or the railway, have since the nineteen seventies a problem with people leaving them for the cities in the urbanization. Currently there is also the opposite trend with people moving out from the cities, but to live on the country side, not in the small towns.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

This is a report of our examination project in electronics carried out for Bofors Test Center in Karlskoga. The task was to construct an electronic devise for starting up different kinds of measuring systems in exact time during test sequences. The modules that are used today are old and unreliable. Our goal was to construct a prototype, which later on is supposed to be developed into a useful system..

Clinical signs of hypocalcaemia in dairy cows are easily recognized, and a rapid response to treatment generally confirms the diagnosis in the field. However, clinical signs of other disorders in cows, such as toxemia, calving paralysis, or muscoskeletal injury, may mimic those associated with hypocalcaemia. Therefore, making a diagnosis of hypocalcaemia on the basis of clinical signs alone may be difficult. In ambulatory veterinary practices, cow-side tests are useful to make the diagnosis and prognosis easier. Kruuse?s Kalcium Test is a cow-side test based on the principle that calcium ions are necessary for coagulation of blood, and that chelation with EDTA prevent coagulation.

Effektiv utveckling kan göra lika stor skillnad som en eller kanske två extra utvecklaretill teamet. För att ligga i framkant i effektiv mjukvaruutveckling så måste mandefiniera hur man är effektiv och vad det innebär. Man kan med stor framgång se sigom kring hur andra företag och organisationer har uppnått högre effektivitet.I rapporten diskuteras best practice och hur R2Meton AB jobbade i början av 2013.Sedan presenteras en utvecklingsmodell som R2Meton AB har implementerat för attbli mer effektiva. Modellen innefattar bland annat automatiserat bygge, tester,analyser och distribution. En högre grad av automatisering och analyser innebär enstörre enhetlighet och kvalitet.

Räddningstjänsten är ett yrke där risktagande är en del av vardagen för personalen, det finns många olika faktorer som påverkar hur och varför ett beslut tas före och under en räddningsinsats. Denna studie syftar till att undersöka skillnader i risktagande mellan befattningar inom räddningstjänsten, baserat på faktorer som sensationssökning och synen på den egna kontrollen av handlingar och dess konsekvenser. Metoden som användes var en webenkät baserad på två validerade tester för att undersöka dessa faktorer; Sensation Seeking Scale samt Locus of Control-test. Sammanlagt deltog 17 stycken respondenter och alla var män, befattningarna varierade mellan brandman, styrkeledare, insatsledare, ställföreträdande räddningschef samt räddningschef. Resultatet visade en signifikant skillnad i sensationssökning mellan befattningarna där de lägre befattningarna hade störst sensationssökning.

The aim of this essay is to investigate which of the goals in the syllabus, and with that what knowledge of Swedish, four students taking the SFI (Swedish for Immigrants) level 3 course believed themselves to have attained and to compare their self-assessments with their results on the National Test of Swedish for adult immigrants.The method used for the investigation is the individual interview. In addition to taking the National Test, the participants in the investigation were asked to mark the goals they believe themselves to have attained.The results show that the informants who best demonstrated awareness of their own knowledge are able to talk freely about their knowledge and difficulties, and when they mark the goals they believe they have attained, these correspond, on the whole, to how they responded in the interviews.One of the informants finds it more difficult than the others to assess her knowledge. A comparison between her experiences and the National Test results revealed several inconsistencies. For example, she claims that she can communicate in Swedish, but still she didn?t pass the test..

Tidigare empirisk forskning förevisade samband mellan optimism och hälsa, likaså mellan self-efficacy och hälsa. Föreliggande undersöknings syfte var att utifrån könsskillnader mellan kvinnor och män undersöka hur op­timism och self-efficacy samverkar med deras självskattade hälsotillstånd. Deltagarna var 190 högskolestudenter, varav 113 kvinnor, i Mellansverige. Statis­tisk analys utfördes genom t-test, multipel linjär regressionsanalys och jämförelse mellan korrelationskoefficienter. Mätinstrumenten Life Orientation Test?Revised, General Health Questionnaire och General Self-efficacy Scale, samt ett påstående om fysisk hälsa användes.
