In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.

The study aims to investigate student participation as a tool for democratic development in secondary school from a student perspective. Furthermore, students' perceptions of the school's work with student participation in formal and informal contexts are also investigated, with basis in the teaching structure. The results are based on interviews conducted with students who all attend the same class in their last year of high school. Subsequently, an analysis is made based mainly on three different theories: democracy, curricula and sociocultural theory. The result shows that students feel that they are able to practice student participation but the amount of influence they get differs between individuals depending on devotion and commitment.

Bakgrunden till detta examensarbete är ett behov av att införa vibrationsmätning i form av ett tillståndsbaserat underhåll vid AB Sandvik Coromants produktionsanläggning i Gimo. Underhållsarbetet på AB Sandvik Coromant i Gimo bedrivdes vid tidpunkten för studien som avhjälpande och förebyggande med olika fasta underhållsintervaller. Att införa tillståndsbaserat underhåll skulle kunna reducera kostnaderna, samt medföra en ökad uppföljning av varje maskin i form av hälsotillstånd. Målsättningen med examensarbetet var att utvärdera vibrationer som mätmetod. Arbetet har innefattat fyra, huvudsakliga moment.

The ability of a dog to perform some kind of practical work, for example hunting or herding, depends among other things on its behavioural characteristics. In animal breeding it is not always easy though to select for behavioural traits. It may, for example, be difficult to identify traits that are not only heritable but also of importance for the dogs' ability to perform the practical work of interest. Moreover, it is often difficult to accomplish accurate measurements of behavioural traits. When selecting dogs for breeding, it is usually preferable to evaluate them using an objective and standardized bahavioural test, rather than results from field trials.

This thesis deals with the question of how and to what degree Swedish history books for schools changed between the early 20th century and the 1960s. The theoretical foundation for this study is a perspective which treats historical accounts as narratives, bringing meaning and orientation to the present. According to this perspective, historical accounts may be divided into four different types of narratives, traditional, exemplary, critical and genetical. The basis for this division is how the narratives use the past to make the present understandable.The following conclusions are reached:That Swedish history books for schools have changed less, and in a moore gradual way than those dealing with general history. There is a growing use of genetical narratives at the expense of mainly exemplary ones.

Mellan den 25 juni till den 12 juli 1941 genomförde den tyska armén en transport av en division fullt utrustade soldater genom Sverige. Detta har betraktats som den största eftergiften som Sverige gjorde under hela andra världskriget. Sveriges ledning fick några bråda dagar runt midsommaren 1941 att ta ett beslut om tyskarnas överlämnade begäran till den svenska samlingsregeringen. Den innehöll bl.a. en begäran om transitering av en division fullt utrustade soldater genom Sverige.

The following chapters examine landscape architecture which engages in contested territories with an emphasis on the way in which landscape architecture can engage with the issues of divided cities or landscapes with similar social, cultural and physical properties. The project focuses specifically on the potential landscape architecture has for promoting or aiding in the reconciliation process of these areas, by examining the following questions. How can landscape architecture be used to benefit the peace building process of divided cities and landscapes? How can landscape architecture be used in the process of promoting spatial reconciliation in the case of Belfast? The investigation begins with a description of the background to the project in Chapter 1, which functions as a brief introduction to the urban phenomena that is divided cities. It then goes on to introduce the different methods and data employed in order to answer the research questions in Chapter 2. After introducing the problem and the methodology, a global overview of divided cities is performed in Chapter 3. This chapter is divided into two sections.

Aim: My aim with this study is to investigate whether the co-workers in the company Arla Foods is satisfied with the communication between the company and the employees. If there are any changes to be made or if it works well as it is now.Method: I have sent out invistigationforms to 85 co-workers within Arla Foods. This forms included questions about Arla Foods internal communication and how the co-workers apprehend this. I have also made 7 interviews over the phone with co-workers on the dairys around Sweden. Including in these 7 interviews have I also talked and posed questions to representatives for the trades-union within Arla Foods.

Earlier this year the Swedish migration board gave a part of their responsibility for the separated children to those municipalities that have signed an agreement with them, so that the children can get the best handling of their matters and also to lift the heavy pressure of the Swedish migration board. Our aim in this paper is to see how this division is made and which areas of responsibility they have. We want to see how this process is being handled in relation to these children?s rights, the Convention on the Rights of the Child and the Swedish law. To get the best information possible we used a qualitative method.

The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.

Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.

In which ways have composing processes in music appeared over the past 300 years? How may composing processes work today? What does new technology do to this processes?The key purpose of this study is to investigate various composing processes. A further purpose is also to gain an awareness of how we use modern technology by computers and their notation programmes.The research design of this thesis includes a display of literature related to composing processes. along with an analysis of the writer?s own experiences in the area.

The purpose of this study is to ? through a discourse analysis ? examine how the parliamentary committee ? Ansvarskommittén ? legitimizes the need for merging administrative regions. The committee?s investigation is what underlies the present debate on regionalisation and the merging of regions in Sweden. To carry out this discourse analysis, I have used ?What?s the problem represented to be??, by Carol Lee Bacchi as an analytical framework.
