Summary 1. The radius of gyration of α-amylase is 26.9 Å, as found by means of small angle X-ray scattering. This value decreases by 0.5 Å if amylase binds three moles ofβ-cyclodextrin per mole enzyme. 2. In case of partial saturation, the solution contains only saturated amylase-cyclodextrin... mehr

Summary 1. The fact that β-cyclodextrin inhibits the hydrolysis of amylase suggests that β-cyclodextrin binds to the active center of pancreatic α-amylase EC 3.2.1.1. 2. As shown by preparative ultracentrifugation, amylase binds specifically three moles of β-cyclodextrin per mole enzyme and... mehr

Abstract Catalytic activities of BaCuO2, Ba2Cu3O5 and CuO for CO oxidation were investigated. At 250 ° C, BaCuO2 was found to be about 7 times more active than CuO, while Ba2Cu3O5 was found to be only slightly more active than CuO. This result also demonstrates that expensive rare earth elements... mehr

Abstract Catalytic activities of five non-conducting and three superconducting cuprates were measured for the decomposition of NO and the reduction of NO by CO. The concentration of the reactants and the space velocities approximate the conditions of automotive catalysts. In contrast to earlier... mehr

Abstract We give an overview of decidability results for modal logics having a binary modality. We put an emphasis on the demonstration of proof-techniques, and hope that this will also help in finding the borderlines between decidable and undecidable fragments of usual first-order logic. mehr
