Qualitative Indicators of Microbial Cells of Yersinia pestis EV Strain Depending on Their Morphological Traits in Different Temperature Conditions of Manufacturing of Plague Vaccine Preparation

The preference of the (21±1) °C temperature for cultivation of the vaccine strain Yersinia pestis EV in the live plague vaccine biomass production to (27±1) °C is experimentally confirmed. An original interpretation of the mechanism of small cells stability that are formed at (21±1) °C has been proposed. This interpretation stipulates a smaller damaging effect of steam molecules during sublimation in the process of lyophilization

Non-Relativistic Limit for Matrix 1D-Dirac Operators with Point Interactions

Abstract We consider different $$c$$ -dependent realizations $${\mathbf{D}}_{X,{\mathbf{B}}_{c}}^{c}$$ of $$2m\times 2m$$ -Dirac operator with point interactions on a discrete set $$X$$ where $$c$$ is the velocity of light. Our main aim is to show that non-relativistic limit of $${\mathbf{D}}_{X,{\mathbf{B}}_{c}}^{c}$$ as $$c\to\infty$$ is an appropriate Schrödinger operator $${\mathbf{H}}_{X,{\mathbf{B}}_{H}}$$ with point interactions. This result extends the corresponding result from [16] to the matrix case. As a special case we establish that the non-relativistic limit of $$\delta^{\prime}$$ -realizations for $$2m\times 2m$$ -Dirac operator coincides with Schrödinger operator $${\mathbf{H}}_{X,{\mathbf{B}}_{H}}$$ with $$\delta^{\prime}$$ -interactions on the same set

To the Spectral Theory of One-Dimensional Matrix Dirac Operators with Point Matrix Interactions

We investigate one-dimensional (2p 7 2p)-matrix Dirac operators DX,\u3b1 and DX,\u3b2 with point matrix interactions on a discrete set X. Several results of [4] are generalized to the case of (p 7 p)-matrix interactions with p > 1. It is shown that a number of properties of the operators DX,\u3b1 and DX,\u3b2 (self-adjointness, discreteness of the spectrum, etc.) are identical to the corresponding properties of some Jacobi matrices BX,\u3b1 and BX,\u3b2 with (p 7 p)-matrix entries. The relationship found is used to describe these properties as well as conditions of continuity and absolute continuity of the spectra of the operators DX,\u3b1 and DX,\u3b2. Also the non-relativistic limit at the velocity of light c \u2192 1e is studied
