The article explains a new method of relief marking of heat-shrinkable tubing and sleeves made of polymer materials with "shape memory effect." Method of instrument evaluation of relief marking stereometry of installation parts for aviation equipment, made of polyvinyl chloride, polyethyleneterephthalate and polystyrene was developed and the results were explained. Parameters of pin-point relief marking and compliance of point forms to the Braille font standard were determined with the use of the non-destructive method based on the color of interference pattern with precision of 0.02 mm.

The industrial parks sector in Russia is currently continuing to develop steadily. According to statistics, the number of industrial parks has grown from 80 in 2013 to 334 in 2020. From the organizational point of view an industrial park should be understood as a complex production system, the effective functioning of which is possible with ...

The study examined the factors of the attitude of university teachers to tests as a method of assessing educational results. On a sample of 160 university teachers, it was shown that a more negative attitude to tests was negatively associated with the self-assessment of the teacher’s knowledge in the field of methodology for creating tests ...

Active loop extrusion—the process of formation of dynamically growing chromatin loops due to the motor activity of DNA–binding protein complexes—is a firmly established mechanism responsible for chromatin spatial organization at different stages of a cell cycle in eukaryotes and bacteria. The theoretical insight into the effect of loop extrusion on the experimentally measured statistics of ...

Based on the random phase approximation, we develop a molecular theory of self-coacervation in zwitterionic polymer solutions. We show that the interplay between the volume interactions of the monomeric units and electrostatic correlations of charged groups on a polymer backbone can result in liquid-liquid phase separation (self-coacervation). We analyse the behavior of the coacervate phase ...

Сегодня по показателям производства и потребления полимерных материалов и других видов химической продукции Россия занимает далеко не самое почетное место. Почему химия в нашей стране не может развиваться столь же быстро, как, например, в Китае? Почему мы движемся вперед со скоростью, едва-едва превышающей среднемировую, т.е. фактически топчемся на месте, и с какими угрозами это связано? ...

The process of poly(methyl methacrylate) (PMMA) matrix impregnation with mefenamic acid (MFA) in a supercritical carbon dioxide medium has been studied by the full atomistic classical molecular dynamics method. Simulations have been performed for two systems that differ in the polymer sample size (≈270 kDa and ≈1080 kDa) at 333 K and 40 MPa. The characteristics of the systems, ...

Abstract: We have performed comparative numerical calculations using a multiple trapping (MT)
formalism with an exponential and an aggregate two-exponential trap distributions for describing
two mostly used experimental setups for studying the radiation-induced conductivity (RIC) and
the time-of-flight (TOF) effects. Computations have been done for pulsed and long-time
electron-beam irradiations in a small-signal regime. Predictions of these two approaches ...

Abstract: Polymer dielectrics subjected to intense radiation fluxes exhibit a radiation-induced
conductivity (RIC). Polyimide is a good dielectric with excellent mechanical and thermal properties
featuring high radiation resistance currently widely used in the spacecraft industry. Its RIC has
been extensively studied in several laboratories. The purpose of the present study is to make a
direct measurement of the RIC ...

We have investigated the radiation-induced conductivity (RIC) in Kapton-like polymers in which it increases with an accumulating dose at large dose rates and long irradiation times. Such a behavior is very useful for spacecraft applications as it allows mitigating the spacecraft charging problems. Also, we studied ordinary polymers whose RIC steadily falls after reaching an ...
