Miljöinformation i förvaltningsberättelsen :

The first of May 2005 changes were made in the Annual Accounts Act. The 2006 Annual Report of companies with more than ten employees or assets over 24 million SEK must include environmental information in the directors' report if it affects the company's development, result or position. A survey made by KPMG 2007 investigating the environmental information of companies listed on Large Cap Segment of the OMX Stockholm exchange showed that only a third of the companies, included in the survey, complied with the new law requirements. I have examined how the environmental information in the directors' report is formulated and why the information is formulated in that fashion. I have examined seven companies listed on the Large Cap Segment of the OMX Stockholm exchange. Four companies from the materials sector and three banks from the financials sector were included in the survey.

E.ON:s transformatorflöde - en studie av återanvändningen av transformatorer i projekt krafttag

Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.

Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Att Organisera Processer : semesterrekrytering på Sandvik Materials Technology

Bakgrunden till studien är de förändringar i form av minskade produktionsstopp som Sandvik Materials Technology (SMT) infört från och med sommaren 2005. Detta har inneburit att vissa produktionsområden stänger ner sin tillverkning från fyra veckor till inga produktionsstopp under sommaren. Syftet med undersökningen har varit att undersöka hur arbetsfördelning, kommunikation och samordning har skett mellan nyckelaktörer på SMT inför rekryteringen av semesterersättare år 2007. Vi har använt oss av en kvalitativ metod där vi genomfört åtta stycken halvstrukturerade intervjuer och granskat dokument, såsom processbeskrivning och rekryteringspolicy för semesterprocessen. Resultatet har visat på svårigheter i kommunikation och samverkan som vi främst tror har grundat sig i otydliga roller i arbetsfördelning inom processen, då kontaktmannen både har agerat som personalman och kontaktman till de berörda första linjens chefer vi har intervjuat..

Därför väljer vi : om några lärare val av

.The Whole language program is in Sweden generally referred to as ?Kiwimetoden? - ?the Kiwi program? (author?s direct translation) partly due to the fact that the Whole language program originates from New Zealand. Whole language is basically a literacy program and approaches literacy from a holistic point of view. Children learning to read and write should do so in the same natural way children learn to speak their native language which is in the context of authentic language as a whole. In Sweden the program is generally practiced together with a commercial and pre-organised material called ?kiwi? or ?Stjärnsvenska?.

Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Medier på andra språk än svenska: En studie om det mångkulturella biblioteket

The purpose of this master?s thesis is to investigate how librarians approach to the multicultural collection development and which methods they use in providing library materials in minority languages. The questions to be answered are: which methods the libraries use when purchasing library materials in minority languages, how the respondents experience that the minority user groups needs are met in the library and how the multicultural competence of the staff is used in the libraries. For this purpose the qualitative interviews with 6 librarians in Gothenburg are conducted, mainly from the libraries in the immigrant-dense parts of the city, while the study being concentrated on 6 language groups of library users. The study?s theoretical framework is based on theories of multiculturalism, culture, identity and bilingualism.

Rening av väte vid återvinning av aluminium : Purification of hydrogen in aluminum recycling

Detta examensarbete har utförts på Stena Aluminium (SA) i Älmhult. Undersökningen handlar om att mäta vätgashalten genom densitetsindexprover på smält aluminium, för att kartlägga hur vätgashalten påverkas av processtegen vid återvinning av aluminium i SAs produktions-anläggning. I arbetet ingick att undersöka vätgashalten för två olika legeringstyper (EN-AB 43400 och 46000), utvärdera avgasningseffektivitet för de utvalda legeringstyperna och att utvärdera den befintliga utgjutningssystemet. Mätningar för undersökningen är utförda i SAs smältverk, vid processtegen raffinering och utgjutning..

Förutsättningar och hinder för att minska elektronikavfall : En studie över hur WEEE-direktivet påverkar Sveriges förebyggande åtgärder mot elektronikavfall

To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.

Ökad återvinning? En statistisk analys av två teoretiska vägar framåt! : Studenters syn på återvinningsfrågan

Denna studie har som syfte att ge underlag för beslut om hur återvinningsföretag borde gå tillväga i sina försök att höja återvinningsgraden. För att kunna uträtta detta, kommer jag att undersöka Tonglets och Barrs teorier och rekommendationer. Jag kommer även att leta efter bevis som stödjer att det finns en bristande överensstämmelse mellan individers avsikter och deras beteende..

Restspänningar i arc-förångade (Ti(1-x)Al(x))N ytskikt

This report is the written documentation of a project work carried out at the Division of Engineering Materials at Luleå University of Technology in cooperation with Seco Tools AB. The project deals with the analysis of residual stresses in Ti-Al-N thin film grown on WC/Co cutting inserts. The composition of Al varied from 0% up to 75%. Increasing the Al content in the Ti(1-x)Alx N compound improves the compressive residual stresses even after annealing of the material. The experiments have been performed in a high temperature x-ray diffractometer (HTXRD) where the interplanar atomic spacing was determined in-situ and subsequent converted into stresses.

Feng shui i trädgården :

Our environment affect us, not least gardens. By practising the ancient Chinese art feng shui, one could find tools how to create harmony and balance in gardens. By paying attention to different energies working with colours, shapes and materials one can create a nice garden with good feng shui. The philosophy, however, includes much more than what plants or what hard materials to choose in the garden. It describes different energies, the movement of energies, which we can learn to live in harmony with.

Teknisk undersökning av stafflimåleri ? Med fokus på två dörröverstycken från Röhsska museet

This bachelor thesis is a study in the analysis of paintings with focus on the technical exami-nation within the framework of ATSR. ATSR is a methodology based on an interdisciplinary study with the aim of putting the object in its context.The study is based on questions concerning which information the object can give, how we access this information and how it can be put in a larger context. My thesis contains three major parts. First a short overview of methods of analysis used in this form of investigation is presented. This is followed by two case studies which exemplify the technical investigation.

Den globala uppvärmningen i skolans läromedel : En jämförande studie av sponsrade och förlagsutgivna läromedel

Today the talk about global warming and climate change are on top of the public agenda. There for schools and schoolbooks also debate the issue of global warming. A newcomer on the school stage is the sponsored school materials that studies show to be a growing phenomenon. In a debate like that of global warming which is filled with uncertainties and so much political and economic interest, I find it interesting to study how these schoolbooks talk about the issue.In my study I have tried to analyze and compare how school materials for primary school discuss the phenomenon of global warming. I have compared two different types of schoolbooks.

Val av material och utformning av sinnesträdgårdar för gravt utvecklingsstörda :

The purpose of this thesis was to determine what materials should be used when creating a stimulating garden for intellectually handicapped people and whether there are materials that are better than others to use in this kind of environment. How the materials preferably can be used and how the environment should be designed to satisfy the need of each individual will also be discussed. Seriously intellectually handicapped people have the same level of intelligence as a normal 0-2 year old child. It is important to point out that these individuals can not be compared to a normal child in other aspects than the level of abstract thinking and perception of reality. As the grown up intellectually handicapped people have remained a lot longer on this stage of intelligence they have got more experience. (Kylén 1981) It is important with a lot of different experiences for the brain to develop normally, which implies the use of many different materials to achieve the best stimulation (Kylén 1981).
