Validering av Casmo-5M / Simulate-3

The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).

Analys av data från flyglaserscanning :

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

Svinnoptimering VTIS1

The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.

A systematic reviewAuthor: Karin Andersson and Cecilia BjörertzSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 hpType of paper: Examination paper, 15 hpDate: 2012-05-23Background Today allergy is a major public health issue and one of our most common chronic diseases. It would be most profitable if there was a way to prevent the emergence of allergies, both regarding the community and the individual. The antiinflammatory property of omega-3 influences the immune system and is thought to have a preventive effect on allergic symptoms. To investigate whether the mothers intake of omega-3 during pregnancy and lactation affects the child?s future development of allergy is therefore of high interest.Objective To examine if omega-3 supplement given to mothers during pregnancy, or pregnancy and lactation, is shown to be beneficial in children with heredity to develop allergy.Search strategy Articles were collected from the data bases PubMed, Cochrane and Scopus.

Lilla Hjärtat och alla små brokiga bibliotekarier ? En studie av hur Lilla Hjärtat hanterats på folkbiblioteken

This bachelor's thesis is an investigation into the public libraries'actions following the debate of Stina Wirséns character LillaHjärtat, featured in picture books and films for young children.The character was accused of being racist, due to its similarity tostereotypes such as pickaninnies. Because of this, the books'existence in public libraries was questioned.The purpose of this study is to investigate how librarians havedealt with these books, and what they have based their decisionson. To explore the background of these decisions we have usedPatrick Wilson's theory of cognitive authority (1983). We haveexamined which cognitive authorities have been used in thedecision-making process of how to handle the books containingLilla Hjärtat, and why these cognitive authorities have beenchosen. The method used in the study is qualitative interviewswith seven librarians working in public libraries throughoutSweden.The results of the interviews show that the librarians? mostprominent cognitive authorities have been authors and illustratorsof children's books.

Sponsor or Die - En studie om imageöverföring vid mindre events

Studies conducted on event marketing have mainly focused on larger events. Managerial implications, marketing techniques, and theories in the field have hence dominantly addressed events of larger nature. Event marketing however is a growing phenomenon in the marketing mix. Brands are using event marketing to a greater extent. Brands are increasingly using small events as a marketing tool in order to create brand awareness and brand image; this goes for both small brands and large brands.

Territoriell stigmatisering. En litteraturbaserad studie om möjligheten att använda begreppet ?territoriell stigmatisering? i förklaringsmodeller bakom ojämlikhet i hälsa.

Introduction: Public health is based on the determinants of health. They mutually influence each other. Structural factors and life conditions contribute to health inequality both within and between countries. Health inequality can be seen between different social groups, which can be the cause of differences in living conditions, health behavior and disease vulnerability. One of the consequences of this is segregation which means that certain groups live apart, where this distribution can be connected to economic resources and/or ethnicity.

Den kommunala folkhälsosamordnaren söker sin arbetsroll

Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

Effekter av en idrottspsykologisk utbildningsintervention för friidrottstränare : med fokus på tränares förhållningssätt och ungdomars motivation och upplevelse av tävlingsnervositet

Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.

Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

Avgång av lustgas från luftningsprocessen på Käppalaverket

The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.

Universell kunskapsorganisation: identifiering av ett framväxande forskningsområde genom citeringsanalys.

An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.
