The problem of description a wave field generating by system coherent point sources is considered. This discussed for two well-known approximations, the Fresnel and Fraunhofer patterns, correspondingly. It shown, that validity both approximations has to contain dimensionless small parameters. First them parameter area second one corresponding observation area. In framework pattern Laue conditio...

Due to their aesthetic value and high compressive strength, dentists have recently employed ceramics for restoration materials. Among the ceramic materials, zirconia provides high toughness and crack resistant characteristics. Residual stresses develop in processing due to factors including grain anisotropy and thermal coefficient mismatch. In the present study, polychromatic X-ray (Laue) micro...

Site-directed mutagenesis and Laue diffraction data to 2.5 A resolution were used to solve the structures of two sequential intermediates formed during the catalytic actions of isocitrate dehydrogenase. Both intermediates are distinct from the enzyme-substrate and enzyme-product complexes. Mutation of key catalytic residues changed the rate determining steps so that protein and substrate interm...
