This study is about the use of textbooks in teaching English as a second language and about teachers? attitudes and opinions of using textbooks during lessons. The aim of the study is to receive a deeper understanding of the use of textbooks in English teaching and to learn about why teachers choose whether to use the textbook approach or not. The study contains an analysis of the textbooks the teachers in our study used. The analysis shows the actual content and the types of texts together with the design and the structure of the textbooks.

The purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C). The program is written in Visual Basic .NET and I choused that program language because it is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.

Denna rapport har utförts hos Anders Krahner AB i Skillingaryd som ingår i koncernen Proton Group AB. År 2005 omsatte Proton Group 920 mkr med 730 anställda medan Anders Krahner omsatte 160 mkr med 90 anställda. Anders Krahners kunder finns främst inom fordonsindustrin.Syftet med rapporten är att studera om möjlighet finns att optimera produktionsflödet för två artiklar i befintliga lokaler. Genom att studera vad som påverkar genomloppstiden för artiklarna negativt kunna ge förslag på hur detta kan förbättras. Frågan är om detta kan ske i dagens lokaler eller är nybyggnation enda sättet att effektivisera produktionsflödet.

A growing issue in the construction industry is how production can become moreefficient by using logistical solutions. Companies can minimize the cost of a project byreducing the time to perform the work.The purpose of this report was to examine the logistics related to pipe trenches forSIAAB. The report's focus has been on solving problems and planning that wouldfacilitate the work of the project Vaksala-Lunda Etapp 3.The case study consists of interviews with SIAAB's employees and an observationwhere the progress of a traditional pipe trench has been documented using checklists.Questions to the report?s case study come from the theoretical part, which is basedon literature on construction management and logistics in general. The observationlasted five weeks and the biggest time-consuming events that affected the pipe trenchduring this time, has received most attention.

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.

med denna uppsats var att ta reda på den upplevelse studenter och lärare har av Kursportalen isitt dagliga arbete. Forskningsfrågan i uppsatsen var för det första: ?Vilka styrkor ochsvagheter finns det in användargränssnittet för Kursportalen vid Göteborgs universitet ochhur kan svagheterna förbättras?? För att komma fram till det behövdes en ytterligareforskningsfråga: ?Vilka delar av Kursportalens design upplevs av användarna som brarespektive mindre bra?? De olika funktionerna i Kursportalen utvärderades först genomenkäter till lärare och studenter vid de tre institutionerna Informatik (flyttade sedan till ITuniversitetet),Företagsekonomi och Svenska. Det viktigaste resultatet av utvärderingen var attden grafiska designen: layout, teckensnitt och i viss mån även färgerna, var bra ochkonsekventa medan navigeringen, främst för studenter, var svår..

This research looks into the modern revival of opera based on the study of two recent productions of Giuseppe Verdi?s Don Carlo; the first is the 2010 production at the Gothenburg Opera in Gothenburg, Sweden and the second is the 2013 production at Großes Festspielhaus in Salzburg, Austria. The goal is to discover what aspects a contemporary audience can relate to and identify with and why opera is still relevant today. This has been done partly through a semiotic analysis of the visual image (e.g. set, costume and lightning) and partly through a hermeneutical analysis of the themes in Don Carlo.

The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it. This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.

Lean Production har blivit det produktionskoncept som många av dagens företag har som modell när de utformar sina produktionssystem. De första stegen mot ett flödesinriktat ?lean? produktionssystem tas ofta genom att transformera produktionen. Detta i sin tur ställer ökade krav på materialleveranser Just-In-Time, materialpresentation och låga lager. För den interna logistiken innebär inte sällan dessa krav betydande merarbete i form av t.ex.

During the last few years, there has been a lot of debate regarding the price ofelectricity on the Swedish market. According to a recent survey from Sifo, anon-bias governmental institute for consumer research and testing, the priceof electricity is what worries Swedish households the most. An investigationof the eciency of the Nordic power grids inuence on the Swedish spotprice is therefore both relevant and valuable. Three quarters of all electricityproduced in the Nordic region is traded at the Nord Pool Spot power market.This survey examines how much of the variation of the swedish spot pricecan be descried by the variation of the nordic system price and how much iscaused because of ineciencies in the power grid. Primarily, linear regressionwith adjustments for endogeneity and heteroskedasticity has been used in orderto analyze data obtained mainly from Nord Pool Spot and Vattenfall AB.The results show that the variation of the system price can account for all butabout 40% of the variation in the Swedish spot price.

Title: To make a living by library music; Opportunities and prerequisites.

What is required to make a living by composing and producing music today? This is a qualitative study made by interviewing six persons, who all in some way work with this kind of music. The result shows that in order to reach out and place the music, an active net working, a deep knowledge in music production, in a wide range of music genres, is crucial.

Bakgrunden till denna rapport är det stora antal vindkraftverk som det idag finns planer på att bygga i Sverige. I Jokkmokksliden utanför Malå i Västerbotten påbörjades byggnationen av en vindkraftverkspark under 2010 vilken kommer att bestå av 18 vindkraftverk ritade av en tysk konstruktör. Fundamenten för vindkraftverken är massiva gravitationsfundament där armeringen är särskilt komplicerad att montera och kräver en stor arbetsinsatts. Syftet med denna rapport är att undersöka om och hur man genom att tillämpa nya metoder och planeringsverktyg kan öka produktiviteten och därmed minska arbetsinsatsen. För att uppnå detta har en djupstudie inom Lean Production utförts.

I den konkurrensutsatta tillverkningsindustrin är det viktigt att ha effektiva processer för att kunna hålla nere kostnader och samtidigt hålla en hög kvalitet för att kunna erbjuda attraktiva produkter till konkurrenskraftiga priser. Lean Production är en produktionsfilosofi vars fokus är att eliminera alla former av slöseri som inte skapar värde för kunden. Ursprunget till Lean Production kan härledas till fordonsindustrin och det japanska Toyota Production System. Systemets tanke byggde på en effektiv produktion för att kunna möta konkurrensen från större amerikanska konkurrenter som kunde dra nytta av storskalsfördelar i sin massproduktion. Ett av inslagen i Toyota Production Systems var att lagra material i nära anslutning till produktionen i så kallade supermarkets.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.
