Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Social work is a profession where documentation about people?s behavior and life circumstances is common. In the beginning of the essay we ask ourselves, if these descriptions about people can be problematic? To explore this, we studied social documentation, from the past. We used a historical source because history can help usunderstand the social work that is being conducted today.

As a member of the EU, Sweden has, in some cases, transferred the controlling rights to the Union. This means that the rules defined by the EU must be followed in all member countries, including Sweden. The European Agricultural policy constitutes the largest part of the EU's annual budget and is in contrast to many other areas fully funded at EU level. The last decade, many new regulations on chemicals and pesticides have been introduced which brought great changes and a lot of work throughout the Union, including Sweden. Sweden has always had a strict policy on chemicals and has been at the forefront when it comes to sustainable agriculture and environmental management.

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

The big change is a project where I created patterns on fabric. It is a collaborative project with Lotta Niemi. She studied fashion and textile designers and tailors from the Swedish School of Textiles in Borås and University of Technology in Sydney. The collaboration was to create designs on fabric for her upcoming clothing line for women, Fall / Winter 2013. The clothes will be sold online, in stores in Sweden and Japan.For Lotta Niemi?s clothing line, I wanted to create exclusive designs, rich patterns that worked out handmade and digital.

In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.

Most of the clothes sold in Europe today are produced in developing countries where the production costs are lower. The exploitation of the developing countries has led to that the inferior working conditions in these countries have attracted attention from media and NGOs. Globalisation makes company activities more transparent and the absence of transnational laws calls for alternative regulations. Many companies in Europe has since mid 1990s developed codes of conduct to satisfy the demands of external and internal stakeholders. EU also brought Corporate Social Responsibility to it?s agenda in the beginning of the 2000s and subsequently signals of approaching laws were given.

Att ha en god planeringspolicy för samtliga produktionsavsnitt i en produktionsanläggning är en viktig del i en organisation. Inom en industri med många produktvariationer och artiklar är det lämpligt att anpassa flera planeringsmetoder för effektiv planering mot samtliga operationer. I en av Sandviks produktionsenheter för skärtillverkning i Gimo var fokus riktat till att förbättra planeringspolicyn mot lågfrekventa beläggningsprocesser. I denna studie presenterar och optimeras planeringen mot två beläggningstyper vardera inom Physical Vapor Deposition (PVD) och Chemical Vapor Deposition (CVD). I grund för detta examensarbete finns en teoretisk studie, simulering samt fallstudier på Sandvik Coromant AB.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

More and more companies open up facilities and stores in countries all around the world. Entering a new country means a new culture, a new language, different norms and values and new people with a different way of thinking unlike what you are used to. In order to survive and be successful in this new country means that you have to adapt to the new culture and its components you encounter.The purpose of this thesis has been to identify possibilities and barriers in the Middle Eastern culture affecting international clothing companies. Furthermore it has been investigated how these companies must adapt their products and promotion to this culture.In order to obtain relevant data for achieving the purpose of the study interviews and observations was made at three international clothing companies in Tehran, Iran. These were Mango, United Colors of Benetton and adidas.

Konsumtion är något vi ägnar åt oss i vardagen och som inte går att komma ifrån. Nya möjligheter idag, vare sig det handlar om högre inkomst eller större utbud på marknaden, gör att det skapas nya begär och att den nya konsumtionen efter ett tag känns nödvändig. Idag konsumeras därmed fler varor än någonsin tidigare. Men konsumtionen av varor och tjänster påverkar miljön, och det under hela sin livscykel, från utvinning av råvara till då den blir till avfall.Konsumtion av mode är ett exempel på konsumtion där man uttrycker sina begär och sin längtan. Mode som ofta uttrycks genom kläder ger stimulans till konsumtion och mode och trender förändras snabbt, vilket innebär att det är svårt att hålla kolla på hela produktionsledet och hur miljön påverkas.

The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
