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.

I detta arbete presenteras en metod för bestämning av fri kotinin och totala mängden kotinin i urin och serum. Metoden bygger på hydrolys av prov (för total bestämning av kotinin) och extraktion i metylenklorid. Bestämning av kotinin har gjorts med HILIC-MS/MS..

Thymidine kinase 1 (TK1) is an intracellular enzyme involved in ?the salvage pathway? where the uncomplete parts of DNA are transformed into DNA precursors. The expression of TK1 is cell cykle specific, with the highest level during S-phase when DNA-synthesis is most active. One kind of TK1 is present in serum and an increase in TK1 activity in serum is due to either the level of DNA synthesis in the body or the number of cells dying in a state of replication. This can be used and is used as a marker for prognosis and evaluation of treatment in human patients with leukemia and lymphoma.

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.

Ledinflammation eller osteoartrit (OA) är en vanlig orsak till hälta hos häst. De metoder som idag används för att diagnosticera ledinflammation är förhållandevis ospecifika och allt för ofta diagnosticeras ledinflammation när skadan har blivit irreversibel med radiologiska skelettförändringar. Genom att mäta förekomsten av olika inflammationsmediatorer vid OA kan denna kunskap i framtiden förhoppningsvis utnyttjas för tidig diagnostik och utvärdering av behandling. Syftet med denna pilotstudie är att studera förekomsten av de två proinflammatoriska cytokinerna interleukin (IL)-1? och high mobility group box protein (HMGB)-1 i ledvätska och serum från halta hästar och korrelera dessa till kliniska fynd. Studien innefattar 14 hästar som vid klinikbesök uppvisat en initialhälta.

Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.

Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis. TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.

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.

Huvudsyftet med studien var att undersöka vilka faktorer som upplevs påverka skidskyttars koncentration positivt och negativt. Vidare undersöktes även....

Bensylpenicillin är den mest använda antibiotikan till häst i Sverige idag. Den beredning som skrivs ut till djurägare är framförallt bensylpenicillinprokain, men många hästar får kraftiga biverkningar av preparatet. Biverkningarna kan vara milda så som skakningar eller nervositet, men kan också bli livshotande. Forskning visar att prokain kan vara orsaken till majoriteten av biverkningar, vilket gör att bensylpenicillin utan prokain kan bli aktuellt att använda för att minska risken för biverkningar och öka djurvälfärden. Att byta antibiotika till trimetoprim i kombination med sulfonamid är ej önskvärt då det antibakteriella spektrat då vidgas.

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.
