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.

AimThe purpose of this study has been to examine attitudes towards dance in a broad sense, among Swedish schoolchildren. The study has been done with three different questions in mind: What do pupils think and express about dance? Are there any differences in attitude towards dance between girls and boys? And how do the pupils relate to gender conceptions in connection to dance illustrations?MethodEight pupils 12 ? 14 years of age have been interviewed separately during physical education lessons. During parts of the interviews dance illustrations were used in order to encourage the pupils in their discussions, especially when asked to relate to dance and gender conceptions. The statements have been interpreted from a gender theoretical perspective.ResultsMy interview study shows that male pupils to a larger extent than female pupils inhabit hostile feelings towards dance as part of physical education lessons.

The aim of the study was to examine Swedish preschool and school teachers views upon mother tongue education and cooperation with mother tongue teachers, research covering both topics are very limited. Data collection method for the study were interviews with three teachers from each type of school. The interviews were then transcribed, summarized, and finally analyzed based on the study's theoretical premises, a socio-cultural perspective, Kumashiros theory of non-oppressive teaching and constructivism. The results of the study showed that all teachers considered mother tongue education as important, but time constraints and workload prevented teachers from desirable development of mother tongue education. As for collaboration between teachers and language teachers, most teachers felt that such a thing does not exist, while those who have experience in this type of collaboration believes that it occurs to a limited extent..

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.

The purpose of this Masters thesis has been to examine the importance of libraries for girls leisure time in secondary school. Focus has been on the use of the library as a leisure activity. Interviews were carried out with six girls of the ages 13 to 16. The conclusion of the study is that the library is of importance for the girls mostly through its books. Reading turned out to be an important leisure activity for the girls and the books provided by the library were of significance for their identity development.

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

The intention of the study is to investigate pedagogues understanding of physical activities in preschool. Should special activities be planned in order to stimulate children´s progress in motor skills? I also want to find out if pedagogues found the acitivities in preschool curriculum which says that the aim is to develop children´s body perception and teaching children how to care for their own health. I have interviewed seven pedagogues and focus of the question lied within motor skills and the joy of movement among preschool children. The result shows that pedagogues regard it to be important to stimulate motor activities and to encourage joy of movement in preschool.

Knowledge organization is perceived as a central, constituting activity defining the notion of libraries. Critique calling for a new theoretical foundation voiced by active researchers within library and information science concerning the current knowledge organization has been utilized as a point of departure. Specifications concerning a new theoretical foundation implied by these critiques are considered within this thesis and theory found in The Order of Things by Michel Foucault proposed as an alternative theory for understanding knowledge organization as a human science where meaning, value and representation, by which the ordering of things is possible, is acknowledged as a result of human activity and history. Thus meaning, value and representation must be perceived as dynamic. An example of implementation of the proposed theory has been achieved by the use of bibliometrics.

The title: ?Klara färdiga GÅ? can be translated as ?Ready steady GO?, and is ment as a request to start move. In this project I want to invite people to walk more by creating creative, demanding and playful walkways and paths, where the body can be allowed to work just a tiny bit harder.It?s because walking means exercise and fresh air, for free and without spetial equipment. Walking can also be fun, it allows people to stop, change direction and experience things.I think activity should be fun, inspired by children playground my project is a contribution to how adults might stay healthier in a city, where too often healthy activity is solely confined to the gym or sports fields.

The purpose of this paper is to explore how practicing teachers have included their education in their teaching profession. The five teachers who were interviewed expressed that they lack experience in dealing with administrative issues, conflict management, parental contact and how to manage stress. There has been prior research on how teachers perceive their everyday working lives. Those results showed that teachers are becoming stressed by not knowing how to handle certain situations.My results showed that the teachers were to busy so they created their own methods on how to deal with phenomena that the education have not treated or discussed. The interviews were analyzed with the help of two constructivist concept, authenticity and activity .Authenticity focuses on knowledge is created and constructed by everyday situations.

Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.

This thesis is about a language-stimulating activity, called the Book Teddy, which take placein Markaryd, a small municipality in southern Sweden. The activity is described and someexamples given of the Book Teddy's visits to the homes of parents and their preschool children.Similar activities in Värnamo, Kumla and Borås, which have been inspired by the BookTeddy are also described.Facts about children's psychology, language development and child language illustrate theimportance of stimulating language acquisition in the early years. An important example is"The Bristol Study", a longitudinal study of preschool children.A questionnaire was sent to 93 parents, whose children were bom in 1991. 53 parents or57% answered. The analysis was made out of these 53 questionnaires.

The aim of this Master´s thesis is to examine which type of regime the state Iran is. There has been much research on this issue and the discussion is not over yet. I have departed from three theoretical perspectives in order to understand which type of regime the Middle Eastern nation is: theocracy, democracy and hybrid regime. The theocratic regimetype is composed by David L. Websters archeological theory about governments ruled by God.
