Radiative effects accompanying a fluxon—antifluxon collision on the background of a localized inhomogeneity (microshortor microresistance) or in a randomly inhomogeneous long Josephson junction arestudied. The total emitted energy andthe corresponding threshold value of the bias current density for radiative annihilation of a fluxon—antifluxon pair into a breather are found. Theobtainedresults ...

Mean angular momentum of two objects encountering from almost circular heliocentric orbits up to their Hill spheres is studied. Results of these studies are used for discussion of models of formation of binaries at the stage of rarefied preplanetesimals. Some collided rarefied preplanetesimals could have a greater density at distances closer to their centres, and sometimes there could be two ce...

a structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. the  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-batch r...

Nanopores are extremely developed and randomly distributed in shale gas reservoirs. Due to the rarefied conditions in shale strata, multiple gas transport mechanisms coexist and need further understanding. The commonly used slip models are mostly based on Maxwell slip boundary condition, which assumes elastic collisions between gas molecules and solid surfaces. However, gas molecules do not reb...
