The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the Laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the Laboratory and, in addition, an example of how to make a self classification of a mixture.

Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the Laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

Background ? The last 20 years healthcare has been facing increased demands on efficiency and increased customer satisfaction. This despite reduced resources and increasing demand. These demands are presents in all departments within healthcare organisations, including medical laboratories that currently receive an ever-increasing number of remittances. Laboratory flows are quickly becoming overloaded with samples and related materials.

High levels of ammonia in grass silage have been up for discussion by Swedish advisers. One reason is that it is more difficult for the rumen-microbes to utilise high levels of ammonia. A low level of ammonia is also good because if the cattle can use more of the protein in the silage, they don?t need so much protein concentrate. That is very good for the economy at the farm, and it is also good for the environmental problems caused by high levels of ammonia. In this project, 24 samples of silage have been taken at 20 different farms in the south west of Sweden.

A bioslurry reactor was built for the bioremediation of TNT contaminated waste from the demilitarization industry. The field test was conducted at Vingåkersverken in Vingåker, Sweden, to see if results from Laboratory studies could be repeated in a full scale reactor. The goal of the project was to optimize the reactor to such a degree that it could be used to handle the waste produced at Vingåkersverken and also that this technique could be applied for remediation of contaminated soils. Unfortunately the samples taken during the full scale field test were destroyed by the shipping company and no analysis was possible. A later attempt by the Biorex research group has also been unsuccessful to reduce the amount of TNT using the bioreactor.

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological Laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

This report documents the process of designing a Laboratory exercise in Fourier analysis at Vetenskapens Hus (House of Science) in Stockholm. The lab is designed for high school students studying science or technical education. It focuses on the physicalunderstanding and mathematical description of sound, in particular music. A model of such a lab is presented in this work; containing a review of the mathematical theory, summary of educational research in the field, descriptions of the design process and of the investigativework that led to the final result. The designed material for the lab includes developed computer programs, visit leader tutorial and description for teachers. .

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch Laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch Laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

The purpose of this thesis is to try to find out what effect subject oriented projects like Energiutmaningen has on the teachers, with a focus on teachers? physics education. What was the experience for the teachers who participated and what effects did the project have on them. Four teachers were interviewed through qualitative interviews. From the result it showed that the most experienced teachers, who have been teaching physics for many years, gained a new perspective of their teaching, through their participation a development showed in their education.

There has been a lot of debate in media about mathematics teaching in grade school in Sweden. Many students experience that mathematics in grade school is abstract, which leads to decreased interest of mathematics in early years. An international study indicates that Swedish students in class 4 do not fulfill the mean for mathematics according to EU/OECD countries. The study also shows that Sweden practice a textbook driven education, compared to other countries. The aim for this study was to find out how a few pedagogues for class F-6 teach mathematics, and why they have chosen to educate the way they do.

PAPRO operates within the Forest Research company and their mission is to develop value-addingindustry solutions. At present there are no good ways for mills to easily test the printing quality on newsprintpaper. There is a great need for a fast way to do this on different paper qualities; with a Laboratory-offset press this can be both a time and money saving method. At PAPRO Forest Research, NewZealand, a Laboratory offset press has been developed and designed, during the past seven years, concerningthis issue. Earlier projects were made concerning the press, e.g.

There is a constant change in the world of school, new curricula and syllabi are made and the view of teaching and learning is changing. The desire to improve maths teaching in Swedish schools is strong, especially by Laboratory work. How is it then that several teachers in our schools are still using the traditional way of teaching mathematics, which I consider to be relying a lot on the textbook and work for an automated approach?The purpose of my study is to investigate how three different math teachers on an F-5 school in the southern Stockholm area, choose to work with mathematics and why they choose to work according to a special approach. In order to obtain the information I seek, I have chosen to use the qualitative method to get a better understanding of my results.

The data acquisition system COMET developed by Saab AB contains a unit for signal conditioning and A/D conversion, called KSM. The varieties in signal conditioning constitutes of a number of specific PBAs and maintenance as well as reconfiguration of these are complicated not to mention costly. This thesis has aimed to investigating whether the signal conditioning circuits can be replaced by a general purpose, programmable solution. If so, how can this be done? The development has been carried out by evaluating ideas through the use of a Laboratory environment and has resulted in an analog design for Laboratory purpose.

The aim of this thesis is to study the teaching methods that provide the greatest learning effect for children in grades 6 in the subject of physics. One class was divided into three equal groups, each group was educated in a specific way. The three teaching methods that have been investigated are: film with reflection, Laboratory work and traditional lecture- teaching. The research question of the study is: "Which method of three selected, causes the greatest understanding of the properties of air??.
