Punctuation and its functions in Russian educational slide presentations

This paper focuses on the up-to-date issues of graphic text organization of Russian presentation slides of university lectures in different subjects. The serialization, delineation and stylization functions of punctuation and suprasegmental (typographic) devices specifying the linguistic ‘uniqueness’ of the particular genre/register of the scientific discourse are considered. The specific nature of the use of these devices compared to that of the presentations in English consistent with the preliminary analysis of the communicative intents of the lecturer and the target audience is discussed

High Prf metal vapor laser active media for visual and optical monitoring

In this paper the feasibility of using metal vapor lasers for visual and optical monitoring of fast processes is discussed. The theoretical calculations consistent with the experimental study have been performed. The possibility of visualizing objects with pulse repetition frequency of the brightness amplifier up to 60 kHz has been demonstrated. The visualization results of the corona discharge are also given

High frequency CuBr vapor brightness amplifier

In this paper, the experimental studies of copper bromide vapor brightness amplifiers operating at high pulse repetition frequencies are presented. The obtained results show that the injection of active hydrogen-containing additives allows to increase the radiation (gain) pulse repetition frequency in active elements with a diameter of the active zone larger than 1 cm

Modification and simulation of the power supply of a metal vapor laser

The modification of a power supply circuit used for pumping metal vapor lasers is analyzed. The results of OrCAD simulation of the processes that occur in the power supply are presented. The effect of the capacitance ratio on the charging process of a storage capacitor is described. The mode which provides more time for the recovery of the thyratron is discussed. The results of the development of the small-size high pulse repetition frequency laser with up to 3 W average output power are presented
