It is well known that nature offers an abundance of materials and processes that can be adapted in low-tech fashion, to fabricate systems capable of removing pollutants from wastewater. During the last decade, extensive basic and engineering research on such natural treatment systems have led to improvement of the quality of discharged wastewaters. However, the mechanisms of natural treatment and
A new method to estimate the microstructural parameters of anisotropic twophase composite material is derived. The parameters are estimated using information from measurements or from numerical experiments. The method is used to derive new bounds on the elective tensor that incorporates information from measurements of a related parameter. These new bounds are called cross-property bounds. New tig
Popular Abstract in Swedish Sedan 1900-talets början har jordens medeltemperatur ökat med ca 0.9 grader, vilket bland annat resulterat i mer extremt väder, varmare världshav och att världens isar smälter med översvämningar av kustregioner som följd. Det är numera accepterat att denna temperaturökning med stor sannolikhet beror på människans utsläpp av växthusgaser, ex koldioxid (CO2). KoncentratioThe thesis work was performed with the aim of increasing knowledge and understanding of the combustion of oxygenated fuels and intermediates. This was accomplished in two steps: experimental measurements of the laminar burning velocity to expand current databases and development of a reaction mechanism. In the first part of the project, the laminar burning velocity of oxygenated fuels and interme
