SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.

This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.

The purpose of this paper is to analyse and discuss clinch-nails found at an excavation at terrace II in the Garrison of Birka, on the island of Björkö in Sweden. This type of clinch-nails is common in Viking age Sweden and is usually interpreted as coming from boats. The study will try to show that these types of nails could have been used in several kinds of wooden constructions. It will also show how the nails were made and what kinds of tools were used by the Viking smiths. The study has shown that this type of nails were used in several different types of wooden constructions such as boats, sleds, cart bodies, coffins, Birka's ramparts and buildings.

In article 1.2 c) EC regulation 852/2004 it says that the regulation is not applicable to producers who directly supply small quantities of primary products to the final consumer or to the local retailers who in their turn directly supply the final consumer. An almost identical regulation can be found in article 1.3 c) EC regulation 853/2004. The supply by a primary producer of small quantities of primary products, of animal origin or not, are consequently excepted from these two hygiene regulations. In article 1.3 EC regulation 852/2004 and article 1.4 EC regulation 853/2004 it says that the member states are to establish national rules in their national legislation as to the regulation of exception for small quantities. The aim of this study was to investigate the handling of small quantities of primary products distributed locally in Sweden but also the handling of these products in other countries.

Systems development methods has always been an important part of the systems development process. It affects not only the product, but also the organization itself. Today more and more companies are abandoning the more rigid traditional methods for the more flexible agile ones. A transition like this is bound to affect the product and the organization, but in what ways? Is it a difficult transition to make, and how does it affect social environment and dynamics? Does it change how people communicate information to each other? This study was conducted at a local branch of a larger international IT-company.

This qualitative study is based upon interviews with librarians. It investigates the librarians? opinions on material adapted for disabled people and examines strategies used to market user friendly services for the disabled. The study explores librarians? views about streaming directly on the internet.

Image editing software offers unlimited possibilities to alter an image. Provided that digitalinnovation is not altogether positive, it is important to develop knowledge of its negative sides. Thispaper examines the use of digital image processing from a critical IS perspective. Throughqualitative interviews with professional retouchers, the study provides a picture of their ethicalrelation to the software they use for retouching images in advertising. Though, it turns out that thecustomers who order the retouching holds responsibility for what is altered.

The aim of this study is to investigate ex-Jehovah's witnesses' experiences with accessibility in relation to sexual and reproductive health. The purpose is to build on the understanding of how closed Christian communities view the power over their own bodies in relation to sexual and reproductive health and rights (SRHR). The results are examined and analyzed through Foucault's ideas about power. The thesis is built upon an exploratory point of view, where the focus is to examine the experiences of former Jehovah's witnesses. The theoretical framework assumes that there are different types of power relations, specifically in the form of biopower, disciplinary power and governmentality. Through semi-structured interviews, six former members have been interviewed. The results indicate the complex relation between Jehovah's witnesses and several forms of power.

AbstractThis study examines the use of dance in the special education classes in high school. The purpose is to study the teachers? thoughts about dance within this school form. I want to see if they see any gains from having dance as a subject, and what might these be? Earlier research states that dance has a positive influence on mentally handicapped children and young people, and that it strengthens their general development.

Democracy is said to uphold the dearest values and be the most moral system. But it cannot be characterized as a rigid "syste" but a continuously changing political framework, under which aims and values can be fulfilled - and replaced.The increasingly diverse and ever-changing environment of contemporary democracies forces change upon the systems' natural evolution, which makes their future features uncertain and unforeseeable. A powerful change-force doctrine does however claim change is mainly (or merely) caused by the power of ideas; the elite power over ideas can thus provide a natural foundation for the analysis of the direction of development for democracy. This study aims to provide such a foundation by reconstructing empirical and normative descriptions of democracy at two certain points in time, following extensive government studies.As a tool for analysis, this study identifies values of substantial and procedural character central to democracy theory and discourse. It further creates ideal types of democracy based on these values, to which the nature of democracy is measured.

The aim of this essay is to examine the ambivalence that I consider work of solidarity carried out from majority position to be associated with, and whether it makes sense to understand the relationship between majorities and minorities involved in this work by using the concepts of race and whiteness. Through Ruth Frankenbergs work on white women and race I consider whiteness to be a racialized position, and through Sara Ahmeds phenomenology of whiteness, which describes racialization as made through the orientation of bodies, I investigate how this racialized position is shaped and maintained by the solidarity work. The study is based on qualitative interviews with four White women engaged in two organizations that works on integration of female immigrants through creating jobs in a cooperative and through educating in national and familial democracy. The work of solidarity told of by the interviewees seems to produce racialized notions about immigrated people of color, which acts as a counterpart to the whiteness that the interviewees themselves possess. At the same time, the work also challenge this binary division, especially by incorporating the non-white women in what in this essay is called "the white world"..

Examensarbetet går ut på att frambringa några principkonstruktioner till axialfläktar med fasta inställbara skovlar åtFläktWoods. Fläktarna det rör sig om är stora industrifläktar med en diameter mellan en och fem meter, som används för atttill exempel transportera ner luft i gruvor. Endast förslag till principkonstruktioner tas fram och ej en färdig produkt, syftetmed rapporten är i första hand att ge FläktWoods konstruktörer ett annat synsätt på problemet. Två olika delar av fläktenundersöks, dels fästet av skoveln på hjulet, dels själva hjulet i sig. Tillvägagångssättet är att från formulerat problem tasförst några förslag fram, de utvärderas sedan och de bästa går vidare till nästa steg.

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

Det är viktigt att vägarna håller så länge som möjligt. En faktor som har en påverkan i asfaltens långvarighet är bitumen. När bitumenet föråldras försämras dess egenskaper som ökar risken att skador uppstår på asfalten. Med hjälp av olika tillsatser kan bitumenets egenskaper förbättras. En av dessa egenskaper är bitumenåldring.
