Flame propagation experiments in stoichiometric H $$_2$$ –air are conducted a smooth 482-mm-long, 10-mm $$\times $$ square-cross-section channel, closed at the ignition end and open opposite end. Direct observation is used to track flame acceleration dynamics. The effect of facility specific parameters (i.e., energy, boundary conditions near end, window material, settling time between filling i...

This paper concerns the reconstruction of the absorption and scattering parameters in a time-dependent linear transport equation from knowledge of angularly averaged measurements performed at the boundary of a domain of interest. Such measurement settings find applications in medical and geophysical imaging. We show that the absorption coefficient and the spatial component of the scattering coe...

The article presents an outline of the requirements concerning the planning of preclinical and clinical studies, necessary for the legal approval of a medicinal product. It describes the clinical research plan of innovative and generic pharmaceutical products, taking into account the specific situations in which the assessment of biological equivalence of a generic product is not possible based...

We argue that in the high energy QCD a true black disk wave function consists not only of many gluons but also from many quarks. This corresponds to necessity of nonvacuum reggeon loops in formation of a black disk. The result comes from decomposition of the black disk S-matrix in characters on group manifold. Usually black disk defined as some dense state, which absorbs any projectile. In this...

numerous parameters influence bit selection process, which considering all them is not normally feasible. existing methods use limited number of these parameters to choose a suitable bit for a specific drilling condition. one of the widely used methods is cost per foot. specific energy and drilling strength are another methods currently used for bit selection. different methods of bit selection...
