Den ortodoxa kristendomen i skolan : En analys av den ortodoxa kristendomen i svenska läromedel

This essay is about the representation of orthodox Christianity in Swedish educational material. With the help of my analytical approach inspired by Michel Foucault, I have studied material used in school for the subject Religion. I have limited the educational material in two ways. First, the main reason for this is that I am only interested in material written and produced from the year 2010 until today. Secondly, the material I have chosen to focus on is written for the grades 7-9 and for high school.

Automatiserad Konstruktion av Varmkanalsystem

The thesis has been carried out in cooperation with Master Flow AB, Västervik owned by the EWEBE Group. The company produces and sells hot runner systems that are tailor made for the customers.The problem that MasterFlow AB has encountered is in the construction of complex hot runner systems in SolidWorks. With several different lengths, fronts and endcaps that builds the nozzles of the hot runner systems, is affecting the problems for MasterFlow AB. The purpose of this work is to automate the design of hot runner systems so it does not overload the CAD-system SolidWorks.To gain an understanding of the problem, there have been several studies and observations at the company, where the focus has been on how the work is done with the design of hot runner systems. By using help from the corporate management, enough information has been collected to find a solution to these problems.The implementation of design automation has been based on a flowchart that was created.

Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac

Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

Intern materialhanteringsutveckling på Kongsberg Automotive AB

This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.

Effekt av gameplay på lärande

Syftet med uppsatsen är att försöka determinera vilken effekt mer avancerade gameplaymoment i serious games har på inlärning. Bakgrunden går igenom nyckelbegreppen gameplay och varför mer avancerat gameplay kan leda till mer effektiva lärospel tack vare förbättrat flow. Skriftspråket kanji förklaras kort och de problem som människor som försöker lära sig det ofta stöter på.En studie har utförts med hjälp av fyra olika spel med syftet att lära ut kanji. Tre av dessa spel har designats så att de endast skiljer sig i hur avancerat deras gameplay är. Dessa spel har testats mot varandra för att se om de var olika effektiva på att lära ut kanji.

Tidiga membranförändringar i hingstsperma som används för artificiell insemination :

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

Vattenkemin i Fyrisån under snösmältningen

Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.

Effekten av mjölkkors rang på ?antistresshormonet? oxytocin, mjölkavkastning, mjölkflöden och besökstider i mjölkningsenheten i ett automatiskt mjölkningssystem :

The study was carried out at the Kungsängen Research Centre, Department of Animal Nutrition and Management, Swedish University of Agriculture Sciences, Uppsala. The technical development in dairy production has resulted in a housing system where feeding and milking is done automatically without human contact, a so called automatic milking system. The motives for utilising an automatic milking system, is to increase the animal welfare and to decrease the need for manual labour. However, the system does involve a change for the animals, among the effects is the deprival or the diminishment of a chance for synchronous behaviour and the animals have to agree among themselves in which order they use the feeding stations and the milking unit itself. How and if this affects the animals well-being and production is yet to be solved. A possible way to form an opinion on this, is to study the animals ranking order along with hormone profiles and production. The purpose of this work was to study the effect of low- vs.

Dynamisk massbalansmodellering av fosfor i Östersjön

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

Utredning av alternativa distributionssystem för Holmen Paper

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

Hur påverkas företags kapitalstruktur av lönsamhet och marknadsekonomisk tillväxt? - En studie av svenska börsnoterade företag i branscherna industriteknik, medicin och material

Ett av de främsta nyckeltalen som speglar om företaget är framgångsrikt eller inte är lönsamhet. Då lönsamheten för företag generellt tenderar att vara hög då den ekonomiska marknaden där företaget verkar är gynsam, kan man säga att företagets lönsamhet borde vara hög i högkonjunktur och låg i lågkonjunktur (Yeh & Roca, 2012). Med detta resonemang borde det kunna finnas en koppling mellan ett företags skuldsättningsgrad, konjunkturen och lönsamheten.I den här studien har fyra olika skuldsättningmått undersökts där det huvudsakliga skuldsättningmåttet är totala skulder genom totala tillgångar (TD/TA). Studien har valt att undersöka företag i branscherna industriteknik, medicin och material. Syftet med studien är att försöka bredda och styrka det spektrum av teorier som finns tillgängliga genom att besvara studiens forskningsfrågor om ekonomisk tillväxt och lönsamhet kopplat till skuldsättningsgraden.

Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

Kvalitetssäkring av Clas Ohlson AB´s grafiska produktionsflöde

The question formulation in the essay brought up whether Clas Ohlson works today with their graphical productionflow and if that way of working leads to a desirable result in press. After a dialogue with Clas Ohlson it emerged thatthey had certain problems with the material that came out of the printing presses. Certain colours were not reproducedaccording to the stated values that had been developed. In March -08 an analysis of the graphical production flowspresent situation were done at Clas Ohlsons in order to find out how they worked with their production of print materials.In the analysis, their way to work with color spaces, displays, ICC-profiles, PDF-exports, pictures and printerswere examined. Occasional interviews were also implemented with responsible personnel about how they worked withdifferent aspects.Deficiencies were found on almost all examined parts in their graphical production flow.
