A nanostructured mineral food supplement with a particle size of 60.0–120.0 nm was manufactured from phosphorite by ultrasonic dispersion. It was found that intragastric administration of nanostructures phosphorite to mice is relatively safe: clinical signs of intoxication appeared after a single administration of the preparation only at a dose of 90 mg/kg; a dose of 150 mg/kg caused death of 8% of mice, in which injuries of organs of the gastrointestinal tract were observed. When the preparation was administered subcutaneously, intramuscularly, or intraperitoneally, small phosphorite conglomerates and inflammation of the surrounding tissues and organs were observed at the injection site. Death of 25% of animals was observed in the group of mice which received intraperitoneal injections of nanophosphorite at a dose of 200 mg/kg. 相似文献

The amplitude?temporal characteristics of a supershort avalanche electron beam (SAEB) with an amplitude of up to 100 A, as well as of the breakdown voltage and discharge current, are studied experimentally with a picosecond time resolution. The waveforms of discharge and SAEB currents are synchronized with those of the voltage pulses. It is shown that the amplitude?temporal characteristics of the SAEB depend on the gap length and the designs of the gas diode and cathode. The mechanism for the generation of runaway electron beams in atmospheric-pressure gases is analyzed on the basis of the obtained experimental data. 相似文献

The properties of an electric arc operating in open air at currents of lower than 1 A were studied experimentally. The rod cathode was oriented horizontally. Cylindrical rods and plane plates either installed strictly vertically in front of the cathode end or tilted at a certain angle served as the anode. It is shown that, with such an electrode configuration, it is possible to form a discharge channel much longer than the electrode gap length. Regimes of regular oscillations are revealed, and conditions for their appearance are established. The electric field strength in the arc column and the electron temperature near the anode are calculated. 相似文献

The species composition of fleas in the Moiynkum Desert (Chu-Talas interfluve) and indices of their domination on different hosts was established on the basis of long-term observations (1973–2000). The most significant and prolonged changes in the population density of mass flea species (Xenopsylla gerbilli minax and Coptopsylla lamellifer, parasites of the great gerbil) occur in association with changes of the population density of rodents. Changes in the population density of rodents are usually observed year after similar changes in the population density of hosts. The leading role in the transmission of the plague vector belongs to the flea X. gerbilli minax. 相似文献
