The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records.

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Sweden's population holds today one of the highest life expectancies in the world and an increasing number of Swedes believe that they have good health. However, the problem still remains that there exists significant differences in health between different population groups and neighborhoods. Two neighborhoods that demonstrate high inequality in health status are Rinkeby and Danderyd in Stockholm County.    The purpose of this study was to examine why health differs between different neighborhoods and how residents experience the area and their health. To answer this purpose a combination of statistical data and qualitative interviews with residents in Danderyd and Rinkeby has been used with an additional literature review.      The study showed that the causes of health inequalities between these neighborhoods was primarily concerned with the factors of education, economic conditions, ethnicity, conditions of comfort and companionship and the surrounding residential environment. The population in Danderyd, made up largely of people with high education, good economic conditions and few foreign-born, while the majority of Rinkeby?s population consists of individuals with low education, poor economic conditions and a high proportion of inhabitants of foreign origin, which are determining factors leading to poorer health status among the population.

The purpose of this essay was to study how youths think about their youth and future. Our intention was to study in which order of priority today's high school students in Helsingborg ranked family life, education, career and vagabonding. We also investigated what the term adolescence meant to them.Our main questions were how our respondents looked upon their youth and their future. In which way did they give priority to family life, education, career and vagabonding and why did they give these priorities? Which meaning did the respondents lay in the term adolescence?The study was based on interviews with seven young people, studying at a communal high school in Helsingborg.

The main focus with this study was to investigate if there was a difference in level ofeducation and self-rated health and if it could be explained by the amount of control,demands and social support at work. Theories used in this essay are education, health,and the job strain-model (control, demands and social support at work). We used analready done study by Folkhälsoinstitutet (2004) to examine these questions. Theanalysed sample consists of respondents 12 166 aged 18-84 years. The decline was39, 2 %.

The purpose of our study is to find out how teachers can help their students to learn how to managestage fright. By interviewing high school teachers and high school students and also observe one oftheir classes, we wanted to find out how they think about the causes of stage fright and what youcan do to relieve it. We also wanted to find out how teachers are working to teach students how todeal with stage fright, and how they think that you also could work. As a teacher of music, among other things, the task is to assess and rate the students performancesin music. Several components are based on the students' courage to play on his or her instrument infront of other people.

The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.

I föreliggande uppsats var syftet att i en mixad design med kontroll- och behandlingsgrupp, undersöka om psykofysiologisk strategiträning kan hjälpa individer att hantera stress samt förbättra sin prestationsförmåga i pressade situationer inom golfputtning. Strategiträningen innefattade en kombination av andning-, rörelse och kognitivt beteende. Resultatparametrar var a) fingertemperatur som indikerar förändringar i det sympatiska nervsystemet och b) ett protokoll som mätte prestationsdata. Data har analyserats med hjälp av ANOVA ?repeated measures? i SPSS.Huvudresultatet visar signifikant fingertemperaturskillnad mellan behandlings- och kontrollgruppen.

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything.

The main intention with this study was to explore how parents, employed in three Swedish small- and medium-sized companies, experienced their combination of work and parental leave. The investigation was carried out by a questionnaire, and the 21 participants estimated the attitude from and the treatment by mainly the management and the colleagues. The answers were analyzed both from a perspective of gender and in the aspect of high- and low utilizers of parental leave. The results showed that although both men and women generally estimated the attitude from the management and the colleagues towards parental leave to be positive, the parental leave was divided traditionally and unequally between the parents..

The purpose of the study is to examine, describe and analyse how a selection of parents to children with Asperger syndrome understand, experience and cope with their parenthood. To attain this purpose we focused on these following questions;How does the respondents view their parenthood?; What kind of strategies does the respondents use to cope with their parenthood on the basis on their child with Asperger syndrome?; How does the respondents experience the mesosystem interact with them regarding situations contenting strenuous and stress?We chose to do a qualitative study by conducting separate interviews with eight parents to children with Asperger syndrome. Then we analyzed the answers using an abductive research, we tested the empirical data against our choice of theoretical perspectives. The results shows; that several of the parents in the study have experiences of high strenuous and stress in combination the several roles their parenthood contained.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
