Formal Languages and Automata VI:-algebraic systems and transducers
... starsemiring-omegasemimodule pairs. We dene !-algebraic systems and characterize their solutions
of order k by behaviors of algebraic nite automata. These solutions are then set in correspondence to !-context-free languages. Then we introduce rational and algebraic transducers, and abstract !-families of power series over quemirings and prove that rational and algebraic power series of nite and innite words constitute such abstract !-families of power series.

Determination of the optimal approach to measuring the spleen sizes by sonography
... positions three methods of measuring and calculating the volume of the organ were used. During the processing of the results, it was revealed that optimal visualization was provided in the patient’s supine position, the orientation of the ultrasound transducer along the long axis of the spleen. One patient obtained different volume values — the average difference was 40—70 ml, and in some cases reached 150 ml. This indicates the influence of additional factors on visualization — these include ...
Influence of hematopoietic growth factors on the activation status and functional activity of human T-lymphocytes
The authors present the results of a study proving a direct effect of GM-CSF and Epo on the functional activity and activation status of T-cells in varying degrees of differentiation. The obtained data demonstrate immunoregulatory and anti-inflammatory properties of Epo and CSF-GM. The study shows the direct impact of hematopoietins on the T-cells functional activity in hematopoietic immunoregulation.

Way of shortening the inclusion of antennas of the transducer of the impedance shoulder vibrator
A method is proposed shortening of vibrator antenna. Capacitive reactance is compensated offset by the inclusion of the extension of the inductance coil in the shoulders vibrator. This interpretation of the short tape antenna gives the opportunity to increase the power of the radiation virtually reducing the efficiency of the antenna system, in a result of losses on the inductive element.
