The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Prediktionen av aktieprisutvecklingen har alltid legat i intresse för den finansiella marknadens aktörer. Flera studier har frambringat värdefulla prediktorer för aktieprisutvecklingen. Som en relativt ny prediktor av aktieprisutvecklingen har varians riskpremium rönt uppmärksamhet i forskningsvärlden. Varians riskpremium har i studier visat sig vara träffsäkrare i prognostiseringen av aktieprisutvecklingen än de traditionella prediktorerna som P/E (price over earnings ratio), CAY (consumption wealth ratio) och dividend yield. Varians riskpremium kan även betraktas som ett mått på marknadsimplicerad riskaversion med negativ korrelation till BNP-tillväxttakten.

Music has always been an important form of communication and it can be found in many different contexts including aesthetical, cultural and emotional forms. In the globalized society of today music can be distributed fast through radio, TV, CD: s and the Internet. For many people consumption of music is an important part of the daily life and it can contribute to shape an individual?s attitudes and personality.The main purpose of this study is to find out whether there are any differences between men and women?s musical preferences. I will apply an explorative approach using qualitative interviews to describe what causes the differences.

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.

Our common future involves many important challenges. People and nature need to improve the relationship in order to reach an ecologically sustainable development. In a society where consumption of products steadily increases, the consumer awareness about social and environmental issues connected to the products becomes an importent factor. More and more companies choose to work more actively with these issues and more and more products get labelled by some of the eco labelling organisations. From the cradle to the gate means that a study has been done on a part of a products life cycle.

Swedish beef production has during the past year decreased while the consumption has increased. It´s imported beef that takes market shares. The purpose with this degreeproject is to investigate if the restaurants in Sweden are using imported or Swedish beef and the reason for their choice. The purpose is to find out if there is something the Swedish beef producers can change to increase Swedish beef in restaurants. My expectation is that the demand for Swedish beef will increase in restaurant and later even among consumers. I have interviewed ten chiefs in different restaurants and asked them the following questions: Is it the price, quality or something else that influences your choise? Does it matter to their customers if they serve Swedish or imported beef? How is the marketing of Swedish beef? It appeared both Swedish and imported beef on the restaurants.

Textilindustrin står inför stora utmaningar när det kommer till forskning, utveckling ochproduktion på ett miljöanpassat och socialt ansvarsfullt sätt. Ökat miljömedvetetande hoskonsumenten har lett till ökat intresse och möjlighet för företaget att arbeta mot ett hållbartföretagande.Examensarbetet är skrivet som en del av kandidatexamen i textilingenjörsprogrammet föruppdragsföretaget BlåKläder AB och utfördes för att även kunna fungera som ett underlag förandra företag i avsikt med att påbörja/utveckla sitt arbete med socialt ansvarstagande.I arbetet presenteras miljöpåverkan av en arbetsbyxa i bomull från råväv till distribuering.Fyra miljöbelastande kategorier har tagits med i undersökningen, där mängden av kemikalie,vatten- och energiåtgång samt koldioxidutsläpp räknades ut per arbetsbyxa av minimumorder. Sammanställning av resultat visar att det används 2,5 kg kemikalier, 10,3 liter vatten,756 Wh energi och det släpps ut 0,4 kg kodoxid vid tillverkning av en arbetsbyxa.Rapporten behandlar och beskriver produktion av en rå bomullsväv medflamskyddsbehandling. Processflödet för hela behandlingsförloppet analyseras i arbetet därbåde kemikalier, energi- och vattenåtgång tas upp vid varje delprocess. Koldioxidutsläppanalyseras som en särskild del av rapporten och omfattar de direkta utsläppen av tung lastbiloch fraktfärja.

Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

Problem: What attitudes do young adults have towards Functional food?Is there any relation between these attitudes and young adults behaviour towards Functional Food?Purpose: The purpose of our thesis is to understand young adults attitudes towards Functional Food and also examine the relation between these attitudes and their behaviour towards Functional Food. Method: The authors of this thesis have used a qualitative method for data collection, focus group interviews.  There were two focus groups interviews performed on high-school students at Alléskolan in Hallsberg. The interview questions and the analysis of the primary data have been based on the frame of reference. Conclusion: Our investigation shows similar results as previous studies about consumers attitudes towards Functional Food. Our respondents had mixed attitudes towards Functional Food.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

The aim of this Masters thesis is to investigate if the ideas of the realistic tale in Swedish literature for children can be identified by examining four books for children. The four books are all published between the years 1965 to 1975. The methods used to identify the ideas of the realistic tale are the concepts of alienation and antiestablishment. By using the theory of true and false consciousness represented by Diderichsen and the theory of Socialisation by Giddens, two questions are addressed. The questions are if the ideas of the realistic tale develop a true or a false consciousness.

The purpose of this study was to evaluate the support program, given to cancer patients in order to promote their own efforts to quit smoking and to study if they kept their changed cigarette consumption 6-18 months after their cancer treatment was done.Method: We have used a descriptive qualitative method with semistructured interviews which were made in the spring of 2010 at Uppsala University. The informants in this study were smoking cancer patients which had been given radiotherapy at the oncology department at Ryhov hospital in Jönköping, Sweden.The results showed that three out of eleven informants were still not smoking after their treatment ended. All informants agreed that information about the effects of smoking on their radiotherapy were important.This study also showed that there are areas in which the support program could benefit from being changed. Of those informants who did not succeed in their efforts to quit smoking, many felt that the support should have been more direct in the sense that the staff should have followed up on their progress more frequently. These unsuccessful informants also stressed that the location for where the information was given could have been more private.

CSR - "Corporate Social Responsibility" is a concept that in recent years has become of bigger importance for companies. Even at McDonald's, which quickly grew into today's 217 restaurants, with up to 430 000 visitors daily. We have investigated how the McDonald's CSR work has evolved over time, how it looks today and what has influenced this development. Things that have influenced McDonald's and led to their CSR work proved to be scandals and changes in legislations. The PR value of working with CSR has also increased and a lot of the CSR work has shown to be economically viable.
