The article describes the developed radiometer for Express measurement of alpha radiation of radioactive elements based on a large-diameter silicon detector. The main element of the PPD detector is made using computer mathematical modeling of all stages of the technological process of manufacturing detectors, taking into account at each stage the degree of influence of the properties of the initial silicon on the electrophysical and radiometric characteristics of the detector. Detectors are manufactured for certain types of devices. The developed radiometer is designed to measure alpha radiation of natural isotopes (238U, 234U, 232Th, 226Ra, 222Rn, 218Po, 214Bi, etc.) in various environments. It also shows the principle of operation of the device, provides a block diagram of the measuring complex, describes the electronic components of the radiometer, as well as the block diagram. Signal transformations (spectrum transfer, filtering, accumulation) are implemented programmatically on the basis of a digital processing module. The device can detect the presence of specific elements in various environments, as well as protect people from the harmful effects of adverse radiation and can be used both in the field and stationary.

<div> <div> <div> <p>A key step in gas-phase polycyclic aromatic hydrocarbon (PAH) formation involves the addition of acetylene (or other alkyne) to σ-type aromatic radicals, with successive additions yielding more complex PAHs. A similar process can happen for N- containing aromatics. In cold diffuse environments, such as the interstellar medium, rates of radical addition may be enhanced when the σ-type radical is charged. This paper investigates the gas-phase ion-molecule reactions of acetylene with nine aromatic distonic σ-type radical cations derived from pyridinium (Pyr), anilinium (Anl) and benzonitrilium (Bzn) ions. Three isomers are studied in each case (radical sites at the ortho, meta and para positions). Using a room temperature ion trap, second-order rate coefficients, product branching ratios and reaction efficiencies are reported. </p> </div> </div> </div>

The results of a study of the effect of wet ultrasonic lamb meat salting on the muscle tissue microstructure are presented, and the technical parameters of the ultrasonic device are justified. It has been established that significant destruction and swelling of muscle fibers, local destruction of the sarcolemma with its pronounced rugosity are observed at ultrasonic salting with a frequency of 35 kHz, the cross-striation is poorly expressed, the tissue structure is disturbed. An ultrasonic salting with a frequency of 26 kHz was accompanied an increase in the number of transverse microcracks and crevices, loosening of muscle fibers, the formation of cavities between them while retention of the tissue structure, which contributes to the appearance of a brine between muscle fibers and accelerates its penetration into the fiber. It allows us to recommend ultrasound at a frequency of 26 kHz for cavitation activation of the brine to intensify the technological process of lamb meat salting.
