Oxalate oxidase catalyzes the conversion of oxalic acid and molecular oxygen to carbon dioxide and hydrogen peroxide. Oxalate-degrading enzymes are of interest for various applications including clinical analysis of the levels of oxalic acid in blood and urine and control of oxalic acid in industrial processes, such as pulp and paper manufacture. In these applications, the presence of oxyanions...

Applying machine learning techniques to large datasets of in situ analyses has been proven be a powerful tool Earth Sciences. However, problems may arise when dealing with minerals such as chlorite, that exist solid solution rather than single, stoichiometric ideal. It can difficult determine whether the variations major element concentrations are due compositional difference mineral interest o...

Abstract Fluid-pressure cycles are commonly invoked to explain alternating frictional and viscous deformation at the base of seismogenic crust. However, stress conditions geological environment fluid-pressure cycling unclear. We address this problem by detailed structural investigation a vein-bearing shear zone Sagelvvatn, northern Norwegian Caledonides. In dominantly zone, synkinematic quartz ...

The study area is located in the western portion of Isfahan, in Shahrekord-Dehsard Terrene. This area is part of the Sanandaj- Sirjan structural Zone. In this area, metamorphosed igneous outcrops contain greenschist and metabasite rocks. These rocks have metamorphed into greenschist facies and belong to the Triassic-Jurassic age. The etabasite is mainly composed of plagioclase, amphibole, epido...

Contamination of perchlorate and chlorate in nature is primarily the result of various industrial processes. The microbial respiration of these oxyanions of chlorine plays a major role in reducing the society’s impact on the environment. The focus with this thesis is to investigate the oxygen-dependent regulation of key components involved in the chlorate respiration in the gram-negative bacter...
