Methodical approaches to bioassay of substances containing unstable functional groups
This article describes the method development approaches for bioassay of substances containing unstable functional groups and forming unstable metabolites using the example of mycophenolic acid, methyldopa and mebeverine metabolite
Preliminary results of the Cerenkov EAS flashes the Crimean Astrophysical Observatory
The facility designed for the study of angular resolution of light in the extensive air showers EAS flashes is described. The threshold energy of the facility is about 3 x 10 to the 12h power eV. The data on the angular distribution of light in a flash and the ratio of the flux in the UV and visual region as a function of the distance to the axis of a shower are given. Obtained results are compared to the published computations
Nonreciprocal transmission of microwaves through a long Josephson junction
Nonreciprocal microwave transmission through a long Josephson junction in the
flux-flow regime is studied analytically and numerically within the framework
of the perturbed sine-Gordon model. We demonstrate that the maximum attenuation
of the transmitted power occurs when the direction of the flux flow is opposite
to the direction of the microwave propagation. This attenuation is
nonreciprocal with respect to the flux-flow direction and can be enhanced by
increasing the system length and proper impedance matching of the junction ends
to external transmission line.Comment: 5 pages, 5 figure
