The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Det har blivit allt vanligare att köpa och sälja företag vilket gör att företagsanalys väcker stort intresse bland revisorer, investerare och analytiker. Syftet med denna studie är att beskriva hur professionella analytiker på investmentbolag i praktiken arbetar inför ett företagsförvärv. Detta kommer förhoppningsvis mynna ut i större förståelse för hur förvärvsprocessen tillämpas i verkligheten. Studien kommer att fokusera på hur värderingar genomförs tills dess köpet är avslutat. Frågan som studien ska besvara är; Hur ser förvärvsprocessen ut för svenska investmentbolag fram tills dess köpet är genomfört?Studien använder sig av en kvalitativ metod och har genomförts med hjälp av intervjuer samt ett beskrivande företag.

Mitt syfte med denna uppsats var att undersöka vilka faktormodeller som i genomsnitt bäst kan uppskatta den samlade risken på den svenska aktiemarknaden i form utav GARCH-uppskattade kovariansmatriser. Vidare att specialgranska faktormodellernas uthållighet då de appliceras under en recession. Slutligen undersöka om och hur globaliseringen utav ekonomin påverkar dessa faktorer. Tidsmässigt var undersökning avgränsad mellan 1996-2005. En GARCH-modell togs i anspråk för att uppskatta den tidsvarierande volatiliteten.

By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.

Since the implementation of the revised IAS-1 in January 2009, the income statement has changed in order to include what is called dirty surplus accounting flows (DSF). Using data for the period 2005-2009 regarding large cap companies listed on the OMX Stockholm we identify DSF in Swedish accounting. First, we present some descriptive statistics on aggregated and individual DSF in Sweden. We find that aggregated DSF and individual items related to securities are significantly positive over time. Second, we perform a regression on returns to test for value relevance and find that aggregated DSF and individual items related to currency translation differences and cash flow hedges are value relevant in explaining returns.

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Syfte: En komparativ studie och beskriva möjligheterna för att skapa en effektiv portfölj av olika aktieportföljer, där det undersöks om faktorerna som företagens omsättningsstorlek, branschen de är aktiva i och valet att ha utländska aktier, har betydelse eller inte för att skapa en effektiv portfölj med hänsyn till dess korrelation, avkastning och risk. Metod: Uppsatsen utgår från en kvantitativ studie, som sträcker sig från april 2008 till april 2010, då historiska aktiekurspriser används för olika sorters uträkningar, som baseras på uppsatsens huvudteorier; CAPM, Sharpekvot och portföljteori. Utgångspunkten är deduktiv, där slutsatserna har dragits från teorierna.       Slutsats: Utifrån uträkningarna, kunde det inte dras generella slutsatser där de undersökta faktorerna inte utmärkte sig i något mönster. Däremot visade sig att det blev högre avkastning till liknande risk eller lägre risk till liknade avkastning när man väljer aktier som är olika varandra, då korrelationen inte samvarierar. Det bästa resultatet är när utländska aktier blandas in i portföljen.    .

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

Title: Alexander Technique - Different thoughts on the Alexander Technique and its effect on the singing voice. Does singing lessons cause tension in the student? What should you as a teacher consider to avoid situations that cause tension? This examination is based on interviews. The persons who have been interviewed are singing students, singing teachers and teachers in the Alexander Technique. The literature and the interviews describe the Alexander Technique as a method that, with support of a teacher of the Alexander Technique, helps you to recreate the balance between the cranium, neck and spine.

By studying literature concerning design, didactics and reflection, and complementing those explorations with interviews with experienced design educators, this thesis challenges the idea of aesthetic media education being purely aesthetic in its characteristics. Drawing from their own experiences as a media aesthetics educator and an industrial designer, the two authors argue that the work flow used within most fields of design, commonly known as the design process, might provide a suitable didactic alternative to a field of education lacking relevant methodology. The literature study offers a better understanding of the design process and how it may be defined and viewed within an educational context. The interviews provide a more practical insight into the world of design education. The result shows that the design process as a didactical method theoretically offers both elements of critical thinking as well as direction and frames for students lacking aesthetic and artistic experience.

Diskussionsforumet Flashback Forum har med sin slogan ?Yttrandefrihet på riktigt!? etablerat sig som det forum på Internet där kontroversiella åsikter och provocerande material får fritt spelrum. Detta gör forumet till en tacksam forskningskontext när det gäller föreställningar om något så allmängiltigt som välfärdsverksamhet. Studiens syfte är att synliggöra de föreställningar om socialtjänsten och socialarbetare som finns på Flashback Forum, bilda en diskurs av dessa och sedan jämföra diskursen med andra diskurser kring samma fenomen. Flashback Forumdiskursen genomsyras av fyra teman; Misstro mot socialtjänsten och socialarbetare, Socialtjänsten och socialarbetares verksamhet, Socialtjänsten, socialarbetare och kön samt Tilltro till socialtjänsten och socialarbetare.

The purpose of this paper is to apply the Dual-Effect hypothesis in Pritmani, Shome and Singal paper (2003), in order to analyze the exchange rate exposure on firms listed on the U.K. market. The study will examine if the foreign involvement of the firm will affect the share price of the firm.In addition to evaluating the Dual-Effect hypothesis in Pritmani et. al. (2003), we will evaluate the effect of foreign interest rates impact on U.K.

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.

In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.

With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.
