Mikroskopering av opaka faser - en studie från Skyttgruvan, Falun.
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.
Common misconceptions about everyday astronomy-related phenomena among students in the 9th grade
Students of all ages host a wide variety of scientifically inaccurate ideas and conceptions about everyday astronomical phenomena, such as the seasons, the moon phases, and gravity. The field of Astronomy Education Research has over the last decade experienced an accelerating growth, although the majority of studies have been conducted in the USA. In this work, the 9th grade students of a typical Swedish school were surveyed by means of a questionnaire in order to probe their conceptual understanding of several key concepts in astronomy. In the end, the number of respondents amassed to a total of 90. The results were analyzed with a constructivist approach in light of conceptual change theory and phenomenological primitives.
Local poultry production in rural Zambia and the effect of light on poultry performance
Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production.
Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

Strategier för bevarandet av natthimlens synlighet : en diskussion om motiv & åtgärdsförslag i ett antal internationella strategidokument
Ljusförorening är ett relativt modernt fenomen som allt mer påverkar tillgången till en stjärnklar natthimmel. Det finns en mängd olika internationella organisationer som arbetar för att minska ljusföroreningar och för att bevara natthimlens synlighet, bland andra International Dark-Sky Association, Royal Astronomical Society of Canada och Starlight Initiative. I den här uppsatsen undersöker jag ett antal strategiska dokument genom textanalys, för att analysera deras huvudsakliga motiv till förändringar och för att få en överblick över vilka sorters åtgärder som dessa organisationer föreslår. De analyserade dokumenten är Astrolabs Practical Guide for Lighting, Dark Sky Societys Guidelines for Good Exterior Lighting Plans, International Dark-Sky Associations Practical Guide, Royal Astronomical Society of Canadas Dark Sky Guidelines, Patersons Sark ? Dark Sky Island Lighting Management Plan, Flagstaff Dark Skies Coalitions Lighting Tips, Starlight Initiatives Defence of the Night Sky and the Right to Starlight och Narisda och Schreuders Light Pollution Handbook.
Visten i Lovö naturreservat
Spending a night out in the nature is away for many to experience a slowerpace of life. Refuge cabins are a typeof open-air facility sometimes provided for more far off locations, yet it is in the vicinity of cities and towns that the opportunity for getting out into the natural environment is mostly sought after. Several nature reservs exist around Stockholm with the good intention of promoting the opportunity for outdoor activities. The aim of this study is to investigate how the provision of refuge cabins can be a means of facilitating and augmenting outdoor life experience in a proposed nature reserv to the west of Stockholm.
En skola för alla? : Möjligheter och svårigheter med integrering av särskoleelever i grundskolan.
This study is about how older people are portrayed in TV- commercials, and what those images are saying about senior citizens as consumers. I?ve chosen two of Sweden?s most popular TV channels that are broadcasting commercials and from those two channels recorded commercials in a period of one week, three times a day (morning, afternoon and evening/night). My purpose with this study was to see when older people stared in commercials, which kind of merchandises they were marketing, in which manor they acted out their roles, and (if possible) say something about the elderly people as consumers..
Coffee Shops och Red Light District en turistattraktion? : En studie om hur Amsterdams image påverkas av sexturism och drogturism
Att en destination utstrålar en stark och positiv image har blivit en viktig faktor för att attrahera turister. En negativ global image av en destination kan bidra till en minskad turism. I denna studie söks en förståelse för hur Amsterdams image påverkas av sex- och drogturismen i staden. Teorier som bemöter primära och sekundära turistattraktioner, sökandet efter nöjes/meningsfulla upplevelser och image segmentering har satts i relation med insamlat empiriskt material hämtat från två enkätundersökningar samt tre semi-strukturerade intervjuer. Studiens analys visar att sex- och drogturismen genererar både en positiv och negativ image för Amsterdam i koppling till vad som är moraliskt riktigt.
