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 aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

The aim of this paper is to analyze and problematize the content in the teaching media Känslan för ord through an integrative perspective. This is done by using two sets of questions based on two of the didactic questions what and how. How is the content of the Swedish subject constructed in Känslan för ord? and How is this content integrated in Känslan för ord? The used material consists of a fairly large amount of literature which provides different approaches, priorities, and methods about the Swedish subject. This literature forms the base for the model used to analyze the course books.The results are based on an analysis of the exercise culture (uppgiftskultur) in the two books and are extensive.

Inledning: En stillasittande livsstil blir allt vanligare bland barn, och aktiva utelekar har fått konkurrens från TV- och dataspel. Många familjer bor i städer, med begränsad tillgång till naturkontakt. Naturen erbjuder spontan fysisk aktivitet, likaså ro och mental återhämtning. Barn som har en tidig relation med naturen blir ofta intresserade av naturen som vuxna. Denna studie undersöker möjligheten till naturkontakt för svenska barn i åldrarna 5-12 år.Metod: Tio mödrar intervjuades angående sina barns samspel med naturen.

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.

With this study we aim to learn more about the relationship between digitalization and the swedish church. We have interviewed two priests and two other persons ? one who got married about five years ago, and one who, at the time of writing, is getting married in a few weeks. In addition to the interviews we found some earlier research that were relevant to us, which we read and compared to the empirics we got from the interviews. In our study we have taken qualitative research into practice since we want our interviewees to really share their points of view on the organisation?s usage of digital media.

This thesis discusses the 2007 elections in Kenya, and its aftermath. The aim is to examine whether or not ethnicity played a major role in the outbreak of violence that followed the referendum. As well as different theories and discussions on ethnicity, I will also try to explain the course of events by using theories of increased civil violence during a democratic transition, and the fact that weak political institutions can cause violence. My conclusion is that ethnicity has played a part in the violence, but is too simple to blame the events following the election on just that. A number of different factors all contributed to the outbreak, but all to a different extent.

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Integration of the labor is becoming increasingly topical, with increasing immigration. Labour market integration has been proved to be problematic, partly due to linguistic and cultural differences between the migrant's home country and Sweden. Difficulties with labour market integration have resulted in high numbers of unemployment and dependence on social welfare. Projects VIAM is an employment project conducted by Folkhälsobyrån AB in Västerås, aimed at finding jobs for welfare dependency immigrants. The purpose of this study is to investigate how the informants on Folkhälsobyrån and administrators on the Social service in Västerås has experienced the work of the project VIAM, development issues and the informant´s and administrator´s perception of factors that are influencing immigrant´s employment situation in Västerås.

certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.

Relationer är ett av de grundläggande band vi har i livet och är en viktig aspekt för den psykiska hälsan. Denna studie behandlar en speciell typ av relation, nämligen relationen mellan kontaktpersoner och deras brukare. Studien fördjupar sig i kontaktpersonernas egen upplevelse av många gånger en diffus relation som de har till sina brukare. Den diskuterar om den betalda relationen mellan kontaktpersonerna och brukarna är vänskaplig eller om den är mer professionell i sin natur samt belyser en del etiska problem som kan uppkomma i den här typen av relation. Den aktuella studien innefattar en kvalitativ ansats och bestod av semistrukturerade intervjuer i syfte att belysa relationen mellan kontaktpersoner och sina brukare.

The field of coping has become more developed during the past decades but there is still a lot to be discovered and discussed. Theories of developmental psychology describe the possibility to map a general developmental structure of how the human mind expands. The aim of this study is to contribute to further research in whether there is a reason why we cope the way we do in relation to age. The questions answered in this study was, what coping two girls, whom lived during the Holocaust, used and how the coping found, were possible to interpret from theories of developmental psychology. In order to answer the questions asked a method called Template Analysis Style and three different theories have been applied.

This study was built on the concept of Emotional Intelligence (EI) as an ability with four branches, to effectively: (1) perceive (2) reason (3) understand and (4) manage emotions. By closely studying the four processes of EI through eight semistructured interviews with psychologists, counselors, CBT-therapists and psychotherapists, a study of participants' stories from real practice was done and then analyzed and interpreted. The purpose of this study was to get the participants to describe and put words on practical experiences that occur with clients that correspond to the four domains that define the concept of EI according to Mayer et al. (2008) and find out about if their way of "doing" EI gets trained and developed after several years of professional activity. The results shows that the practitioners used all four branches of EI in dialog with the client, both intra- and interpersonal.

Äldre erbjuds inte naturkontakt och en miljö som är anpassad efter deras behov på det särskilda boendet. Med en funktionell och tillgänglig trädgård, en lockande och restorativ utsikt och naturelement i innemiljön, skulle de äldre få möjlighet att ta del av naturens positiva, hälsofrämjande effekt. Syftet med studien var att undersöka äldres möjligheter till naturkontakt på det särskilda boendet, där deras utemiljö, utsikt och naturelement i innemiljön studerades. Metoden var en miljöanalys av samtliga särskilda boenden (n=6) i en småstadskommun, samt av äldreboendet Vigs Ängar som i studien fungerade som en referens. Resultatet visar att flera särskilda boenden har trädgårdar som erbjuder kvaliteter som är viktiga för de äldre, men tillgängligheten är så dålig att de äldre inte kan använda någon av trädgårdarna självständigt. Det särskilda boendet erbjuder utsikt mot natur och den egna trädgården, men naturelement i innemiljön är en resurs som inte utnyttjas.
