The purpose of this investigation was to investigate how being outdoors and participating in physical activities affect the concentration in a collection situation among children.The methods I chose were observation of two groups of children two times each and interviews with four educators.The results showed that the concentration in the collected situation depends on past activity, where it has taken place and that the environment has an impact. If the previous activity been more active and physical the subsequent collected situation is calmer and the children more concentrate. The facts that the children have been outside in an inspiring environment that encourage playing and movement also have a position impact on the child´s ability to concentrate. The collected situation is an important moment in the preschool day when the kids need to congregate and get a chance for social interaction and a sense of togetherness with all the children and teachers. The conclusion is that there is a relationship between movement, physical activity and an increased concentration.

The study evaluated the Mutant Prevention Concentration (MPC) of Pradofloxacin on three Escherichia coli (E.coli) strains, 2 wildtypes and one first-step gyrA resistant mutant. We also measured the value of AUC (Under the Concentration)/MPC that prevents growth of resistant mutants. It is of importance to reach a concentration above MPC that prevent E.coli from developing resistance against the antibiotic.We used an in vitro kinetic model where we added bacteria? and antibiotic. The culture flask was attached to a pump with an adjustable pump-speed.

The purpose of this study is to gain a deeper understanding of how preschool teachers are doing to train children with concentration difficulties to maintain their concentration. That children with concentration difficulties increases is something that emerged in this study. In order to facilitate and help these children in the best possible way, you have to know the underlying causes and the factors that contribute to lack of concentration.Iam usinga qualitativeinterview method withsemi-structuredquestions to getanswersto my questions.Threeteachers fromtwodifferent preschoolsparticipated in the survey. What emerged in the study was that large groups of children, long days at preschool and today?s society with stress are major causes contributing to the increasing number of children with concentration difficulties according those interviewed. The teachersworkedprimarilyonan individualizedmannerin which theyassumed thatallchildrenare different andreact differently to theimpressions andstimulipresent in the environment.

Children with concentration difficulties are to a great extent a problem in schools and therefore it becomes interesting to see how possibilities around these children can appear in pre-school. From a pre-school teacher?s perspective, the study aims to provide a deeper understanding of how outdoor education can influence children with concentration difficulties. The method of the study is a qualitative research run-up with interviews that intends to describe pre-school teachers? views.

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 scientific essay is based on four self-perceived situations that all takes place in an outdoor environment. The children are aged seven to nine years. At least one of the children in the groups has some type of concentration difficulties. I have combined my practical experience with literature and previous research regarding outdoor education and children with concentration difficulties. Based on this I have tried to interpret and reflect on the opportunities and problems with outdoor education for children with concentration difficulties, especially so called situational concentration difficulties.

This project has aim to examine how students experience their concentration ability during mathematics lessons in the mornings and afternoons, and how students? learning can be in-fluenced by the concentration ability during mathematics lesson in the morning and after-noons respectively? Which role do the methods of learning play in mathematic depending on which time it is carried out during mornings or afternoons with regard to student concentra-tion ability? In order to find out those issues, I used two methods; (interview and observa-tion).Interview with 4 students and 3 teachers and observations of 4 mathematics lessons based on a qualitative method. In order to measure students' concentration ability during ma-thematics education on various times, I distributed questions to 23 students and repeated it during each lesson that I have observed from a quantitative approach in two classes in a sec-ondary school. In the literature I discuss the definition of concentration, and factors affecting the concentration negatively and positively. What is the relationship between concentration, learning and type of activity and how individuals can improve their learning and attention? In addition I studied two earlier studies on the concentration.

Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Concentration problems have been discussed from a variety of angles and have been problemized in different ways. One approach is to place the major part of the problem on the child independent of its environment. The terms used as an explanatory model are ?attention disorder, impulsiveness, difficulty at finding suitable activity levels, difficulty in understanding rules and instructions? (Kadesjö 2007). Others place the root of the problem in the environment prevalent at pre-school and school.

Abstract The purpose of this study is to examine how teachers in primary school reason about and problematize the phenomenon of concentration difficulties. I want to know what the teachers think characterizes concentration difficulties, the situations in which difficulties creates the most problems, and whether the teachers think that these difficulties solely depend on external factors. To examine this, I chose to do interviews with three teachers in years four to six. I have completed parts of my work with my colleague Elin Preisz. We have used the same purpose and issues in our studies, although Elin has interviewed teachers in preschool. With this we want to be able to compare the reasoning between teachers at different stages in school. The results of my study shows that the interviewees think that it is hard to describe what characterizes the problems in concentration difficulties because the problems is very individual.

Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).

In Sweden there is a long ongoing discussion about computer and cellphone usage during lectures in school. The discussion has mainly covered elementary school up to college students, but this topic is at least as relevant for university students. Today cellphones are so advanced; you can do everything with one that you previously only could do with a computer, the difference is that everyone is carrying one with them all the time. This study shows how concentration during lectures is affected by the cellphone accessibility and usage. With this study we want to find out how university students perceive cellphone usage affects their own concentration during lectures.

Research shows that there is a lack of knowledge of adult students with ADHD. Most of all research focuses on children with ADHD in school. The purpose of this study was to gain a better understanding of how adult learners with ADHD experience academic studies related to cognitive difficulties, emotion, motivation, and their experience of SOC. The questions tried to determine how any cognitive difficulties and emotions are perceived, how students' motivation to study impacted and their experience of SOC based on studies in higher education. To answer the purpose and questions used qualitative interviews based on three students with ADHD using a hermeneutic method.
