The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media.

South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

Det här arbetet har främst koncentrerat sig på att utveckla kunskapen om vad det vidgade textbegreppet innebär samt att undersöka begreppets innebörd i kursplaner och läromedel för Engelska A. Därtill har det syftat till att belysa hur det vidgade textbegreppet förhåller sig till en kommunikativ språksyn. För att komma ifrån de problem som begreppet ?ett vidgat textbegrepp? skapar har här använts ett nytt uttryck, ?kommunikativa uttryck? eftersom det på ett bra sätt fångar upp det man vill uppnå med det vidgade textbegreppet. Metoden som har använts för detta har varit att jämföra de tre första kapitlen i vart och ett av läromedlen, Straight Forward English 5(Harling et al, 2006), Blueprint A version 2.0(Lundfall et al, 2008) samt Core English 1 (Gustafsson et al, 2008). Materialet har jämförts ur två aspekter; dels vilka typer av kommunikationsuttryck som förekommer i texterna, dels vilka instruktioner som har återfunnits i läromedlen och lärarhandledningarna för att bearbeta de olika kommunikationsuttrycken. Arbetet har kommit fram till två viktiga slutsatser. Den första slutsatsen är att många olika kommunikationsuttryck finns representerade i de tre första kapitlen i läromedlen Straight Forward English 5 (Harling et al, 2006), Blueprint A version 2.0 (Lundfall et al, 2008) och Core English 1(Gustafsson et al, 2008). Dock är de övningar som finns med för att bearbeta dessa kommunikationsuttryck i första hand där för att fördjupa elevernas förståelse av texterna.

Forskare har under de senaste decennierna försökt finna förklaringar kring den finansiella gåta, känd som the forward premium puzzel, som har visat sig på valutamarknaden. Denna finansiella gåta har skapats då forskare sett statistiska avvikelserna från det öppna ränteparitetet (UIP) på valutamarknaden. UIP förutsätter att det inte ska finnas någon skillnad i avkastning mellan att hålla kapital i olika valutor, vilket empiriskt har visat sig inte stämmer. Detta misslyckande har tagits som bevis för att valutamarknaden är ineffektiv och att valutaspekulerare kan erhålla en överavkastning. Syftet med studien har varit att genom ett lönsamhetstest, med SEK som grundvaluta, undersöka huruvida valutamarknaden har varit effektiv under åren 1997-2012.Studien utgår från en deduktiv forskningsansats där den teoretiska grunden utgörs av den effektiva marknadshypotesen. Den kvantitativa forskningsmetoden bygger på uppgifter från Datastream om valutors utveckling mellan åren 1997-2012.Vår regression visade på att tio utav tolv valutapar återspeglade the forward premium puzzel.

The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

In the essay the author examines how pilgrimage can be used as a tool to radicalise democracy in a late modern society marked by neoliberalism. Applying a dialectic perspective on social movements the essay puts forward how the pilgrimage movement Pilgrim?s Walk for Future, administrated by Church of Sweden, is working in line with the historical pilgrimage theology - a modern critical ecclesiology- to mobilise political action to prevent climate change. The result of the study shows how PWFF meet the neoliberal hegemony with a mobilisation of alternative values beyond the order of capitalism, in line with Christian theology and tradition. The mobilisation is made possible by new forms of identifications with oneself and the social world that meet a modern power/knowledge- regime based on rational thought, and which questions norms and practises by paying attention to their negative effects on nature and on human life in general.

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable.

Abstract Title:                       Grades at Primary School ? A study of local politicians' arguments in                       connection with the division into grades at Swedish primary schools.Author:                       Annie LinderUniversity of KalmarC-essay in Social StudiesAutumn 2011 The study aims to investigate local politicians' decisions since municipalities took overSwedish primary education in 1990/91. The arguments put forward in support of how stages are organised have been studied, likewise whether municipalities have acted rationally when making their decisions.Six municipalities are included in the survey. They were divided into three educational categories: lower, middle and high level schools; previous and recent schools and F9 schools with pre-schools and primary schools integrated.Minutes from politicians' and civil servants' meetings have been studied and categorised according to arguments for and against. The most common supportive arguments are about economy and organisation, others concern school premises, trends and the wish for a comprehensive compulsory school.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.
