Aim: The aim of this present study was to assess the dental caries prevalence in children and adolescents aged 3-19 in the Nordic countries, and to examine if the caries prevalence is affected by socioeconomic and cultural differences.Method: The study is a literature review based on 20 scientific medical reports based on the aim of this study.Result: Decayed missed filled surfaces (dmfs) of the 3-year-olds varies from 0.3 to 0.99 and from 0.9 to 7.3 in 5-year-old children. The Nordic 12-year-olds have similar numerical values. In Nordic 14-year-olds caries prevalence increases. In the late teens there is a reduction in caries prevalence. Children at Greenland have five times more teeth decayed than other Danish children.

This paper examines the film distribution and exhibition sector in Europe. The general analysis of these sectors? situation was made. Moreover, the comparative and more in depth analysis of three countries by the Porter?s five forces model was made; These were United Kingdom, France and Denmark.

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

We are daily using the public space to move throughout the city. The public space is an important part of our city and it?s where a lot of social activities occur and a lot of different events take place. The outdoor environment in the city should offer the residents nice and varying places for staying. In this essay I will try to understand how the physical environment works and how people moves and behave in the public space.

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.

Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.

The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

This thesis is performed in cooperation with Prodelox AB and JTI (Swedish Institute of Agricultural and Environmental Engineering). The purpose of the project is to generate and develop a WC-technique with a closet sewer that keeps a higher TS-substance than 1.5 %. The WC-technique is mainly directed towards permanent households in sparsely-populated areas and cabins. The goal is to generate concepts of toilets with an extremely low use of water in terms of flushing. The design should be appealing and touch more senses than only the visual.

In recent decades, the concept of corporate culture has emerged as an increasingly important factor in the business world, as evidenced by a rise in research and efforts to direct it in various ways. The pandemic has led to significant changes in work processes and office environments as operations shifted to remote work. The purpose of this report is to investigate the impact of remote work on corporate culture and its potential advantages and disadvantages. Additionally, the report aims to analyze how corporate culture currently looks, considering the potential presence and adaptation to hybrid work. Based on a multi-case study, it includes interviews with ten individuals from five different organizations.

Using interviews conducted within the municipality of Nam Dich, Vietnam, this qualitative study explores how ethnic minority parents and children navigate around the state's supervision in order to preserve their traditional practices of child marriages. Moreover, the research explores the roles and expectations between individuals within an ethnic minority family as a collective unit. Using governmentality supported by the concept of state evasion, culture bearers and empowerment, I argue that understanding child marriage as a phenomenon requires analysis of cultural context. The paper starts with an introduction of the ongoing relation between the Vietnamese state and ethnic minority traditions related to child marriage. While the Vietnamese state ?s modernization projects aim to empower individuals by creating more freedom within the process of marriage and increasing the opportunity for education and work, certain ethnic minority groups want to uphold their cultural ways of marriage when parental arrangement occurs from an early age.

With this essay we would like to examine to what extent the ancient Icelandic literature could count as a part of Sweden?s literal cultural heritage in schools today, if it through seeking information is possible to say whether this literature have any connections to Sweden. Our questions of issue are:1. What kind of connection is there between ancient Icelandic literature and Swedish literary cultural heritage and what are the ancient Icelandic literature premises? in the Swedish upper secondary school?2.

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

This essay highlights the Swedish retail companies? engagement in ethics and environment issues as a part of the business concept. The Customer is today more aware about what is going on in the world than ever before. Two of the main reasons are the Internet and the globalization. In relation to the customer being more aware about the situation in the world today, the demand for products which have been produced in consideration of ethical and environmental values has increased.
