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..

.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?.

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.

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).

Läs-och skrivlärande i grundskolan och särskolan : Två lärare beskriver sitt arbete i svenska

My purpose in this paper is to study teachers' work in reading and writing in primary school and special school. I want to find out if they use the same methods, strategies and Materials to help students learn to read and write. I will find out the answer to my purpose by performing two qualitative observation and two qualitative interviews. Lundberg (2010) is the researcher I relate to during my study. Through observation, I see how teachers work with students in the classroom during a lesson in the Swedish language. During the interviews, I received answers to how teachers work with language, the Materials, methods and strategies they use. I found out that teachers use specific strategies when they help their students. They use a work material that is tailored to curriculum in Swedish language and it is based on the phonics method. .

Glosträning eller lässtrategier? Lärares syn på läsning i gymnasieskolans språkundervisning

Abstract The aim of this study is to find out how teachers view the importance of reading in the teaching of foreign languages. In relation to this, we wish to gain understanding of what teachers want to achieve with reading, how they choose texts and what difficulties they encounter in getting their students to read. Six teachers from three different upper secondary schools in southern Sweden were interviewed for the study. We also examined the text-Materials that they were using for their instruction. The findings show that students read mostly adapted texts from textbooks and, to a limited extent, authentic Materials.

Healing, häxor och helhetstänkande. En studie av new age- litteraturens tillgänglighet på folkbibliotek

The purpose of this masters thesis is to find out if public libraries provide new age Materials or not. My research is done using the point of view of the library users. Do they think libraries hold a sufficient amount of new age literature and do the users find this literature of good quality? To find an answer to this question, interviews have been made with a number of library users interested in new age related issues. Interviews have also been made with librarians, to get their point of view on this rather controversial subject.

Ett nytt pedagogiskt material! : 4DFrame, hur kan man arbeta praktiskt med det?

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical Materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.
