Katterna på Kattstallet i Åkeshov : vilka katter är det som insjuknar?

The aim of this study was to see if there is any group of cats that are at greater risk to get sick and/or be euthanized during their stay at a cat shelter with no-kill policy. The study was conducted at Åkeshov cat rescue center in Sweden and cats that entered the center between the 1th of June 2010 and the 31th of December 2011 was used in the study. This study focused on factors regarding gender, origin, level of socialization, incubation period and the proportion of euthanized cats. In this study, the kind of illness weren?t taken into account. This study showed that the gender of the cat didn´t affect the risk for illness.

Trygghet och trygghetsskapande i arbetslivet

In this paper we examine what security is to the individual and how the individual creates and maintains security in their work. The purpose of this paper is to study how the creating of security in working life is performed. We conduct six semi-structured qualitative interviews with permanent employees in the private sector and we encode our material using thematic analysis. We analyze our material and illustrate our problem area on the basis of Anthony Giddens's theory of ontological security and give examples of how security and creating of security is performed at the empirical field with previous studies in the research area. Our survey shows that security for the individual at work seems to be about having continuity in everyday life, financial stability, a permanent employment, a challenging and fun job and a family in good health and good living.

Den svenska kärnkraftspolitiken : En processpårande fallstudie av svensk kärnkraftspolitik

This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.

Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

Protection of Regional Values - A comparative study of EU and ASEAN

Regionalisation has become an increasingly important phenomenon in a globalized world. As models of regional integration, the European Union (EU) and the Association of Southeast Asian Nations (ASEAN) are two prominent examples. This thesis seeks to explore through a comparative analysis, the different mechanisms and institutions for handling breaches against fundamental values within the two regional organizations. Inter-linked with the issue of the legal-institutional framework is that of what values the mechanisms are designed to protect. The method used for the analysis is first and foremost that of public international and European law, but the thesis also attempts to give a broader picture of the issues presented.

Oxytocin-Ett risktagande eller en tillförlitlig behandling vid långdraget förlossningsförlopp hos förstföderskor

Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil

It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.

Ett kompatibelt control package? - en fallstudie av Metso Power AB

Bakgrund: Under senare år har många företag valt mer processorienterad inriktning påverksamheten, framförallt i syfte för att förbättra kundvärdet. Många företag har enmer hierarkisk struktur i utgångsläget, vilket innebär att vertikal och horisontellstruktur kombineras. Ett vanligt misstag är då att nya processorienterade styrmedelinförs, utan att existerande vertikalt orienterade styrmedel tas bort. Detta leder tillatt företagets styrmedel sänder ut motstridiga styrsignaler. För att öka företagetsmöjlighet att uppnå uppsatta mål, så krävs det att dess styrmedel är kompatibla.I sämre tider är det vanligt att företag formulerar mål med Net Working Capital somgrund.

Prestanda och precision pa? en enkortsdator i ett system med realtidskrav

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Livskvalitet och social livssituation hos patienter som genomgått Ö-cellstransplantation

Aim: To investigate the quality of life and the social life situation, with special focus on the consequenses of fear of hypoglycemia (FoH), in Islet transplanted patients.Method: 11 patients were included, four women and seven men, who have been Islet tranplanted at Uppsala University Hospital during the years 2001-2009. Two questionaires, Short Form 36 (SF-36) and the Swedish version Hypoglycemia Fear Survey (Swe-HFS) were used to investigate the quality of life, in relation to fear of hypoglycemia. Also, telephone interviews were conducted to investigate the patients social life situation in relation to FoH, after Islet transplantation and were analysed using content analysis method.Results: The mean value for quality of life was lower than that in the normal population. Three out of ten patients experienced FoH. Three predominant themes were revealed, one theme associated with pre- transplant, was ?Struggle for control of Social Life Situation? and two themes associated with post-transplant, were ?Regain power and controll of  Social Life Situation? and ?At Peace with the balance between the Present and the Future?.Conclusion: The patients experienced improved control over social life situation and quality of life in relation to FoH may been improved following islet tranplantation..

Ett aktivt Sverige inom ESFP - En inblick kring argumenten för ett utbrett engagemang och hög aktivitet

The ambition of this study is to examine the discussion surrounding the Swedish participation in the European security- and defence policy. By forming feasible areas of arguments the goal is to gain further comprehension in the case of Sweden. These arguments are formed in close relation to the empirical sources; With less public funding there are economic aspects of cooperation, this could also be related to Swedish the industry of defence systems; A high level of participation in the UN is a tradition in Swedish foreign policy, the European battle groups are the perfect tool to further strengthen the UN ability in conflict management and peace keeping missions; Outside the EMU Sweden could face the political margin, to retain influence a high level of activity ought to occur in the integration process; Finally, the future position of United States and NATO is not clear, Europe needs an capacity apart the US to contribute to lasting peace and stability. The arguments are close related to each other, but the main argument is to through ESDP create a tool that will strengthen UN, there is also a wide range of economic arguments related to the industry..

Avgörande faktorer vid affärsutbyten med Polen : en flerfallsstudie inom miljösektorn

Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.

Utvärdering av öppna dikens status och funktion : en förstudie i Västmanlands län

Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

BYGGBRANSCHENS EGENKONTROLLER - DERAS BETYDELSE UR ENERGISYNPUNKT

In order to accomplish that a construction is correctly built, it is critical to obtain a well functioning control mechanism throughout the project. The way to enable this is not by having an independent inspector constantly at your side. Today it is praxis to use check lists and have people responsible of quality to make sure that these are followed. This is where discretionary inspections play their part. These among others are documents needed to com-plete the check list.
