Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.

Inledningen beskriver bakgrunden till de val kring gästhamnsverksamheten på Marstrand som Kungälvs kommun idag står inför. Problemet delas därefter upp i sina separata beståndsdelar och en överblick över Marstrand, privat respektive kommunal drift samt båtturismen och dess utveckling ges läsare. I Metodavsnittet behandlas den kvalitativa fallstudieformen som valts för att undersöka Kungälvs kommuns möjligheter att utveckla Marstrands gästhamn genom att öka kunskapen kring driftsformer av gästhamnar i Skandinavien. Urvalet av gästhamnar preciseras och motiveras samt hur uppsatsförfattarna sökt uppnå god validitet och reliabilitet på uppsatsen. Den Teoretiska referensramen redogör för huvuddragen i Aktieägarperspektivet, Intressent?perspektivet samt Agent?Principalteorin som tillsammans ligger till grund för uppsatsens analys och slutsats. Empirin presenterar resultatet från den kartläggning som gjorts av urvalets respektive hamnar. En inblick i bland annat drifts? och ägarförhållanden, syftet med gästhamnsverksamheten, differentiering samt olika särdrag ges. I Analys och Slutsatskapitlen görs inledande en driftsövergripande analys som lyfter fram likheter och olikheter hamnarna.

This paper is an assessment of whether the Nordic countries constitute an optimum currency area (OCA) or not. Hodrick Prescott-­?filtered data of real Gross Domestic Product (GDP) and rate of employment are used to investigate the similarity of business cycles between the target countries through a series of correlation analysis with Sweden as the base reference country and also by using a linear regression model. Additionally there is an evaluation of trade volume and labour mobility between the countries. Our results indicate that Iceland had the least similar business cycles within the Nordic countries and that the area should therefore possibly comprise Denmark, Finland, Norway and Sweden. .

Anställda med starkt organisationsengagemang presterar bättre och stannar längre inom sin organisation. Syftet med föreliggande studie var att studera organisationsengagemang och dess samband med relation till närmaste chef (LMX), innehavande av chefskap samt kontakt med närmaste chef. En webbenkät besvarades av 224 medarbetare på ett svenskt telecomföretag. Resultatet visade ett positivt samband mellan organisationsengagemang och LMX. Villighet att bidra utöver kraven för sin chefs skull predicerade nivån av organisationsengagemang till störst del.

The aim of this study is to examine educationalists experiences of play as an educational toolin the work to promote the social development in children with autism.The relevant issue, for this study, is: In what way does an educationalist work with play withchildren with autism? What are the results of using play in the educational work? What arethe possibilities and what are the obstacles in using play in educational work?This study has been carried out as a study of literature in the field and qualitative interviewswith five educationalists that are working in a mid Swedish county.The result of the study shows that educationalists have a positive view of using play in theirwork and are using play in varying ways in their everyday work. Using play as a method intheir work always happens according to the ability and condition of the child. They (theeducationalists) think that play has great opportunity and advance as a method and gives thechildren joy, increase their sense of ability, the base for the social participation in play, andthe development of social skills.There is a certain hesitation among educationalists when it comes to using play as a methodfor children with autism , but the most of the educationalists consider play as promoting thesocial development although the development always will happen at the pace(rate)of thechild..

This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.

In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

In the expansion rate of the national as well as the international market, the importance of trademark has been given a central matter. The definition of what can be considered a trademark has been widened. Today?s trademark law defines a trademark as something that can be graphically reproduced. Trademarks can there for contain names, words, numbers, letters or the shape of the goods itself or the packaging.

The well-being of employees has become a key concept in the rhetoric of the company boards and business literature of today. There is however not much statistic evidence of a connection between economic results and the perceived working climate. This thesis sets out to investigate whether there is a positive correlation between economic results and working climate on a work group level. It also aims to study which specific working climate factors influence the results. In order to meet its purpose this thesis analyzes employee satisfaction questionnaire data and economic results from more than 300 work groups.

The purpose of this thesis is to examine the networks of interlocking directors in the 50 largestSwedish companies on the Stockholm Stock Exchange during the years 1990, 1995, 2000, 2005and 2010 and seek explanations for the observed developments.Our findings indicate that the density and concentration of the network has decreased during thefirst ten-year period and stayed constant during the second period. The development of theoverall network is not consistent throughout all corporate groups. Most notablyHandelsbankssfären seems to experience increased density and connectivity whileWallenbergsfären is experiencing the reverse.The changes during the first ten-year period is deemed to come mainly from changes inregulations pertaining to both the opening for international capital investments as well as looserrestrictions on domestic capital investments. These changes have caused decreased concentrationof ownership, as well as the emergence of new owners, which is reflected in the board ofdirectors.During the second ten-year period the changes are more pertaining to the individual boards andboard members, without flowing through into the overall network. Our findings indicate thatthese changes are caused by the increased professionalization of boards and board work, whichhas gained momentum through the creation of the Swedish Corporate Governance Code..

The demands on the adult literacy-rate are very high in Sweden. People with reading and writing difficulties may find it hard to fit into the community and to succeed in school. To accommodate the needs of students with learning disabilities, Swedish schools provide easy-to-understand materials. The purpose of my thesis is to examine how easy-to-read textbooks for high school students are different from regular textbooks. The study was carried out using a content analysis and I examined the books according to criteria specified by the Swedish author Torbjörn Lundgren.

The aim of this thesis is to study different aspects of the public libraries' investment in public access computers connected to the Internet. What level of accessibility can be found at the surveyed libraries concerning the number of computers open to the public, as well as chat and email services? What activities have been taking place with the computers in focus, and what have the goals of these activities been? Is there any control of content, and what aspects of the Internet are, if that is the case, subject to censorship. And how do the governmental policies relate to the surveyed libraries' intentions and activities regarding the Internet? In order to answer these questions, each main library in the 42 largest towns of Sweden was surveyed response rate: 100 %.
