Bakgrund: Ortodontisk behandling utförs vanligtvis på ungdomar och kan innebära en risk för den orala hälsan. Studier har visat att patienter med fast apparatur löper större risk att utveckla svullen gingiva och karies. Syfte: Syftet med studien är att undersöka tandvårdspersonalens rutiner kring munhygien hos patienter med fast apparatur på ortodontikliniker. Metod: Studien är en kvantitativ tvärsnittsstudie i form av en enkät med 11 frågor. Enkäten skickades till fyra ortodontikliniker i fyra olika län i södra Sverige.

A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.

The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.

En fungerande munhälsa är centralt för att människan ska kunna tillgodogöra sig näring och för att känna välbefinnande. Hälso- och sjukvården har gjort stora framsteg som bidragit till att medellivslängden ökat och den äldre populationen blivit större. Tandvården har också gjort stora framsteg vilket bidragit till att den äldre befolkningen behåller sina egna tänder i högre utsträckning. Paradoxalt nog har den förbättrade tandhälsan hos äldre gjort att problemen med tandhälsan ökat på grund av att tandhälsan har blivit eftersatt. Det har visat sig att äldre personer med kognitiv svikt som bor kvar i det egna hemmet har stora munhälsoproblem.

AbstractThis thesis analyzes the Russian Foreign Policy Doctrine from a broad theoretical perspective, with the aim of describing and explaining the doctrine using a number of theoretical approaches. Russia's foreign policy has undergone substantial changes since Vladimir Putin became president in the year 2000, involving a radical shift in foreign policy objectives and thereby moving away from the more confrontational and distrusting policies which characterized the Boris Jeltsin regime. Putins doctrine, based on pragmatism and seeking partnership and collaboration with the West, can be described as a near revolutionary re-orientation of Russia's foreign policy guidelines, meaning a transformation of the country's self image which implies a rejection of great power status and a search for a new role in the international community.Our thesis has examined explanatory variables such as the domestic political situation in Russia, the contemporary international system and President Vladimir Putins system of beliefs in order to describe and explain the doctrine. Our results show that the doctrine is largely a product of Putins personality, values and beliefs, but also to a large extent a consequence of necessities, namely the poor Russian economy and the fact that the country no longer can withstand an all out conflict with the West involving an excessive arms race.Keywords: Vladimir Putin, pragmatism, realism, domestic politics, radical change..

During the later part of the 20th century the amount of children and adolescents in Sweden who reported psychosomatic illness have greatly increased. The main reason is estimated to relate to weak resources in school and school healthcare. Increased resources do not always have to encompass investments for school and school healthcare. Other resources play an important part as well. A child?s domestic situation serves as one of those resources where fundamental knowledge and values are set.

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Research regarding the maintenance of the Sami language shows that the Swedish society has a big influence on the development of the Sami identity and also the maintenance of the Sami language. The assimilation of the Sami language and the traditional Sami religion was forced mainly by the Swedish education form and the Swedish church. In modern times many different forms of Sami identities have been developed due to the scattering of the Sami people, and also because of the urbanization of the Swedish society. The Sami nature religion is still alive in the Sami group, thanks to the mythological stories told and preserved by their oral  tradition. The purpose of this assignment was to make research of how the Sami identity is being presented in three current Swedish books.

The study's purpose was to get a picture of what a number of class teachers know about and their views on the concept of working memory and working memory training and whether this affects their working and teaching in the classroom. The study is based on qualitative interviews and classroom observations and the theoretical perspectives that the study is based on two: didactic perspective and the socio-cultural perspective. The results of my study show that the class teachers' views and use of the concept of working memory is limited, even if they unknowingly working on parts of it in their teaching. All classroom teachers in my study term difficulties that can arise for students as concentration difficulties, which according to previous research can count towards deficiencies in working memory. All of the respondents in this study believe that it is mostly special education teacher who trains working memory, and that they themselves do not have that knowledge. They also believe that the classroom environment is important for all learning. Common to all respondents consider that the topic is important and would like to have more knowledge of how they can help and support pupils with poor working memory. As a special education teacher and teacher you often meet students who have trouble concentrating, and because of this may be difficult to absorb knowledge as when reading.
