Barn och stress.
The purpose of this study is to show how the modern society, with demands, expectations and the time constraints of adults, affects children and the everyday life at the preschool. Our intention is also to show the importance of identify stress symptoms of the children. The study is of qualitative empirical kind and is based on a questionnaire to 19 parents of preschool children at the age of three to five years old. Interviews are made with four preschool teachers on one preschool. An observation of children in possible stressful situations is made during three days each at two preschools. The results show that the modern society affects children and can be stressful. It also affects the everyday life at the preschool.
Uppgradering av biogas i systemperspektiv med avseende på miljöpåverkan och kostnader
Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.
Personer med utmattningssyndrom: : Finns det ett samband mellan subjektiv och objektiv kognition?
Research shows that people with burnout experience a high degree of impairments in a range of cognitive functions including memory, attention and concentration. The overall aim of the present study is to investigate whether there is a correlation between subjective estimates of cognition and cognitive performance with objective tests in people with burnout with a focus on working memory and executive functions. Three specific questions were addressed; First, what cognitive problems are described and to what degree? Second, is the performance of executive and working memory tests related to self-reported cognitive problems? Third, are the self-reported cognitive problems related to measures of psychological distress? The study included 77 patients, 65 women and 12 men, with a mean age of 43.48 years. The results show that patients with burnout perceive themselves as having significantly impaired cognition in everyday life, which is clearly evident on the basis of the self-assessment forms PRMQ and CFQ.
Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase
In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.
Förebyggande förbättringsarbete med Design for Six Sigma
Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model.
Döden är livsviktig : fem kuratorers bemötande av obotligt sjuka och deras bild av de sjukas upplevelser
The aim of this undergraduate thesis was to explore how the welfare officers at palliative units in Stockholm respond to the patients? thoughts and experiences during the last phase of life, as well as exploring their picture of the patients experiences. The research questions of the study were:? How do the welfare officers relate to the patients? experience of their death? ? In what way do the welfare officers respond to the dying patient and his or her experiences?? What knowledge/experience do the welfare officers have and what knowledge/experience do they consider is needed in their profession?To answer the research questions a qualitative method was used where five welfare officers in three different palliative units were interviewed. The empirical material was analysed through meaning concentration and are presented using exact quotations.
Evaluation of a behaviour protocol for use in recording the behaviour of horses following administration of methadone
There is a need for correct and adequate pain assessment in horses. Methadone is used in pain management in horses but the full pharmacokinetic picture of methadone is not yet known. The aim of this pilot study was to develop a behaviour protocol and suggest a reliable recording method for use in a larger research project with an aim to potentially correlate behaviours to concentration of methadone in blood. In this study two coldblooded trotters were given methadone intravenously with doses of 0.1 mg/kg for horse 1 and 0.2 mg/kg for horse 2. The horses were videotaped pre and post methadone administration.

Vad påverkar kvinnlig könsstympning? : en litteraturstudie
BakgrundKvinnlig könsstympning innebär att hela eller delar av könsorganen avlägsnas. I världen uppskattas 100-140 miljoner kvinnor genomgått ingreppet. Kvinnlig könsstympning är främst förekommande i de västra och östra delarna av Afrika samt i Egypten. Ingreppet är inte en religiös plikt utan har sedan 2000 år tillbaka utförts som en kulturell sed. En kartläggning av faktorer som påverkar fortsatt utövande av kvinnlig könsstympning behövs för att få svar på vilka resurser i det förebyggande arbetet som har störst påverkan i avskaffningen av kvinnlig könsstympning.

Laborativ matematik : Vad är syftet? Varför väljer lärare att arbeta laborativt? Vad säger eleverna?
Research indicates that a more hands-on education in mathematics could improve how students relate to mathematics. Laboratory mathematics is a way of making mathematics more concrete. How is the purpose of laboratory mathematics perceived? This thesis has its focus on the pupils? perceptions of the purpose of laboratory mathematics, but the intention of the teacher involved is also investigated. The main research questions asked were:What is the teacher's definition of laboratory mathematics?Which is the teacher's purpose in using laboratory education?How do the students perceive the purpose of the laboratory teaching of mathematics?To answer the questions, I conducted a series of qualitative interviews.

En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood
Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.
Metodutveckling för analys av serglycinuttrycket i blodet hos hundar :
The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.
