The aim of this study has been to investigate students? understanding of fractions when they occur in the practical subject home economics. In order to investigate this, the learning study method was used. Learning study can be understood as a method to gain deeper understanding of what is learnt by students during a lesson to increase learning outcome.The variation theory framework has been utilized to analyze the results of this study. The object of learning was chosen to be addition of fractions bigger than one half when they appear in home economics.

Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.

The waste fractions offered to households in Sweden differ depending on where you live. The responsibility for the waste are grounded by the Swedish law where the municipality are responsible for the collection of household waste and FTI are responsible for collecting all packages and papers that the households sorts out. A new waste regulation is under consideration where the responsibility for the household waste may change. The bulky waste from households is collected at recycling centers where the households leave it in different containers for different fractions. These recycling centers are formed different and the fractions offered in them also differ depending on in what municipality they are located.

The unique ability of wheat to produce leavened bread is mainly due to the gluten proteins present. As consumers are more and more attracted to bread with high fibre content the use of wheat gluten will also increase in order to obtain bread with good volume and appetizing characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the original flour. This method is not widely used in the milling industry but could possibly be of interest if protein rich fractions with favorable protein quality can be produced.

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Breeding-induced endometritis in horses seems to be down-regulated by certain components in the seminal plasma. These components are most likely some of the proteins in the seminal plasma in the stallion ejaculate, the so-called spermadhesins. This study aimed to recognize these proteins and determine their quantities in different fractions of the ejaculate. Fractionated ejaculates from four stallions were used to determine the presence and amount of proteins by way of size-excluding chromatography. All former known proteins, except two, were recognized in this study.

Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.

All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

The purpose of this paper is to examine what opinions parents have of the after school-centre, if they know that it has an objective and what that objective is. This will be examined by surveying parents with children in after school-centre. The questions posed in the study are as follows: Do parents know the objective of after school-centre? What is the general view of after school-centre among parents? The results show that 41 percent know that there is an objective while 39 percent don't. Only 6 percent can describe what the objective is.

The purpose of this essay was to find out whether the students, which had moved from the school of Gustaf Adolf to the school of Elineberg, had been integrated into their new environment. We chose to analyze the degree of integration concerning their schoolwork, how they interacted with the students from the new school, the school of Elineberg, and their level of wellbeing in their new school. We have used two methods, surveys and interviews, to be able to obtain the general picture of how the integration of the students has succeeded.Our conclusions are that the student has adapted well in their new school despite many obstacles along the way. Our essay shows that the students get along well with their new school friends during class, but they don´t socialise in their spear time. Although they seem to have accepted the closure of their old school some students express that they wish the school would be reopened.

The purpose with this study is to examine school-leaders?, school-librarians? and teachers? expectations and aims for their school-libraries at two different schools in the city of Växjö. The study is based on these five questions:· How do school-leaders, school-librarians and teachers think about learning?· What function does the school-library have?· What roles do school-leaders, school-librarians and teachers have in the school-library?· How do school-leaders, school-librarians and teachers experience the co-operation in the school-library?· How would school-leaders, school-librarians and teachers wish that the co-operation should be?To be able to answer these questions I have done thirteen qualitative interviews and studied literature relevant to the subject. Three different theories are used as a theoretical framework; the traditional perspective, individual constructivism and social constructivism.

This study is an attempt to shed light on problems and possibilities of the school library of the Swedish comprehensive school concerning library law and goals of the school and the school library. Many investigations about the role of the school library of the comprehensive school have been carried through. They have all more or less come to the same conclusions. In spite of Swedish library law and goal documents of the school library, the school libraries are often neglected, if not will and commitment are to be found among teachers. Using a model of the school organisation by Gunnar Berg, three cases of school libraries are presented and analysed in a larger organisational and political perspective.

The thoughts of a common school for all children have been around since the 1800?s but was something that was introduced in Sweden first in 1962. When the curriculum for primary school came in 1980 there was a new concept, a school for all. With a school for all it was aimed that all children should have the right to participation and a common education no matter what needs they could have.During my education I have come across the concept a school for all and that is something that interested me. Today?s curricula and school laws aim to ensure that all children have the right to equal education and inclusion whatever needs you have.The purpose of this study is to find out some pedagogues? thoughts and work around the concept a school for all.

The subject of this master thesis is the school library and how we find its potential unutilized. We look at this problem in connection to the democratic assignment that the Swedish school has. The purpose is to elucidate what the democratic assignment consists of and to establish the role that the school library ought to have in this assignment. To describe the democratic assignment we examine and interpret the documents that regulate school and library activities today, including UNESCO/IFLA School Library Manifesto and United Nations Convention on the Rights of the Child. We use critical ideology analysis because we consider democracy to be a sort of ideology and have a critical view of how the school library is used or rather not used in school.
