Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

Om sjukhusbibliotek i Sverige under 1930-talet ? en litteraturstudie av idéer om biblioteksverksamhet på sjukhus

The study concerns the history and development of hospitallibraries in Sweden in the beginning of the 1900 century.Focus is on the 1930 decade, the time of major expansionof the area.

H?llbarhetsprestation och finansiell volatilitet. En studie om sambandet mellan ESG-po?ng och aktievolatilitet

This paper aims to explore the relationship between financial risk and ESG scores in order to assist investors in making investment decisions. We investigate the hypothesis that there is a relationship between the ESG score of a company, and the financial risk in terms of volatility in the relevant company?s share price. The paper is grounded in sustainability reporting and financial risk. With the world facing significant changes and natural disasters, there is an urgent need for action to mitigate environmental impacts to avoid devastating consequences.

Minor fieled study - molecular epidemiologi of rabies in Sao Paulo state and Minas Gerais state, Brazil

Rabies is a fatal zoonotic disease spread worldwide. The most common sources of infection for all animals and humans are bites from dogs or bats. The aim of this degree project was to diagnose and determine the source of infection for 11 rabies samples from São Paulo State and Minas Gerais State, Brazil. Diagnosis was made through direct immunofluorescence assay, mouse inoculation and RT-PCR. The sources of infection were determined by sequencing 234 nucleotides of the 5? end of the N-gene and align these with homologous sequences retrieved from GenBank.

Den lukulliske Lucullus' passioner; om villaträdgårdar, mat och ett romerskt orginal

AbstractFor this exam paper, I have chosen to delve into the life of Lucius Licinius Lucullus, the famous Roman general and statesman of the 1st century BC. Widely regarded as a glutton and degenerate, I will try to examine if these claims are true or completely exaggerated. My research will be based on the works of Plutarch, the great Greek scholar and biographer, who's our main source of knowledge regarding the life of Lucullus. Furthermore, I will examine two of Lucullus's main interests ? his love for villa gardens and culinary delights ? to see in what way they have contributed to the common picture of him as a sybarite.

En flödesutjämnande driftstrategi för Uppsalas fjärrvärmesystem : En ändrad styrning av framtemperaturen

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

Analys av tanniner : från granbarksextrakt

The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.

Kundens förtroende och bild av fastighetsmäklare i Karlstad

Hälsans Trädgård is a project which is going to start in Gamla Linköping, Sweden. The authors were commissioned by Arbetslivsresurs, a company working with work rehabilitation, to select, define and make job analyses on five work tasks at Hälsans Trädgård in Gamla Linköping. A job analysis means an analysis of the demands the job make of the individual. The job analysis used in this study is called The Revised Handbook for Analyzing Jobs (RHAJ) and is from the US Department of Labor (DOL). As RHAJ is an American instrument, the authors produced a form where the concepts are translated into Swedish to make the analysis easier.

Utvärdering och jämförelse av olika fälttester för fotbollsspelare

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Kunskapen, professionen och makten ? En kvalitativ studie om socionomens villkor och förutsättningar

My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

MUSIK TILL GUDS ÄRA - SYNDIGT ELLER GOTT? : En studie av kvinnors musicerande i den tidigkristna kyrkan

This thesis aims to investigate and discuss the possibility for women in the early Christian church to make music, which in the ancient Roman society was something complicated. Afemale musician was looked upon as decadent and dissolute. This idea, in combination with the music ideals of the church influenced by the Neoplatonic movement, and the Pauline statement (1 Cor. 14:34-36), cast women to be completely prohibited in participating even in the psalmody during the service. My purpose is to discuss how this was looked upon in different Christian regions, using the church fathers as the main material source, since this has not previously been well documented or studied..

Textila cylindrar - experiment kring solljusreglering

Working with a three-dimensional shape that adjusts light seemed exciting. Venetian blinds became a basis and source of inspiration in my project. What is a Venetian blind? I arrived at the de?nition ?a surface of angleble pieces for sun adjustment?. From that simpli?ed meaning I started making sketches of what an alternative model could look like.

Terms and conditions (villkor för orderläggning) : En fallstudie på Ericsson AB i Gävle

This final thesis was performed at Ericsson in Gävle between April and June of 2008. Ericsson is a world leading manufacturer of radio base stations (RBS), which handles mobile phone traffic with 2G and 3G technology. The main purpose of this study is to examine if two different types of products (RBS and site material) should have different terms and conditions, today the terms and conditions are the same for both types. During the course of our study we have tried to think of the terms reliability, validity and generalization. The intention in doing that was to keep the thesis at a high academic level. To name an example of this we have tried to keep our minds at an objective level during the interviews and informal conversations.
