Gamma-glutamyl transpeptidase (GGT) is an enzyme believed to play a role in the protection of maturing spermatozoa in the epididymis. Our previous studies have shown that four GGT mRNAs (I-IV) transcribed from the single-copy rat GGT gene are differentially expressed and regulated in the rat epididymis. In particular, the normal expression of GGT mRNA(IV) in the epididymal initial segment is de...

By examining the Fourier transform of the initial datum near the origin, we define the decay character of the datum and provide a method to study the lower and upper algebraic rates of decay of solutions to a wide class of dissipative system of equations.

Exploring and controlling inelastic and reactive collisions on the quantum level is a main goal of the developing field of ultracold chemistry. For this, the preparation of precisely defined initial atomic and molecular states in tailored environments is necessary. Here we present experimental studies of inelastic collisions of metastable ultracold Rb2 molecules in an array of quasi-1D potentia...

the influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. three fungi, coriolus versicolor (c. versicolor) a white rot, coniophora puteana (c. puteana) a brown rot, and chaetomium globosum (c. globosum) a soft rot, were chosen. the mycelia of the fungi were inoculated in to mini blocks of fagus sylvatica (beech) and pinus sy...

Influence of several operating conditions on luminance decay in a green organic light-emitting diode with tris (8-hydrooxyquinoline) aluminum (Alq3) has been investigated by the analysis of its luminance decay curves. The conditions varied were operating current mode (DC or pulse) and environmental temperature (25–120 oC). The decay curves measured were analyzed by fitting the curves to stretch...

This paper is devoted to the analysis of the large-time behavior of solutions of one-dimensional Fisher-KPP reaction-diffusion equations. The initial conditions are assumed to be globally front-like and to decay at infinity towards the unstable steady state more slowly than any exponentially decaying function. We prove that all level sets of the solutions move infinitely fast as time goes to in...

We study the ABC model ( A + B mapsto 2 B, B + C mapsto 2 C, C + A mapsto 2 A), and its counterpart: the three-component neutral drift model ( A + B mapsto 2 A or 2 B, B + C mapsto 2 B or 2 C, C + A mapsto 2 C or 2 A.) In the former case, the mean-field approximation exhibits cyclic behaviour with an amplitude determined by the initial condition. When stochastic phenomena are taken into account...

In this paper, we consider questions of inner regularity weak solutions initial-boundary value problems for the Zakharov–Kuznetsov equation with two spatial variables. The initial function is assumed to be irregular, and main parameter governing decay rate at infinity. results paper are obtained problem on a half-strip. problem, different types conditions (e.g., Dirichlet or Neumann conditions)...
