Biological tissues irradiation doses during the fresh surfaces formation / Дозы облучения биотканей при образовании свежих поверхностей
P. 27–29.
Nikerov V. A., Yunga A. N.
The fresh surfaces formation provided by materials destruction or cleavage often leads to surfaces charging and strong electric fields generation. These fields can create the high energy electrons beams and Bremsstrahlung radiation. For example the destruction of quartz and granite is accomplished by low intensity relativistic electron fluxes creation. However the adhesive tapes peeling is accomplished by significantly more intensive electron beams creation. These beams can provide hard irradiation of skin and other layers of biological tissues during the adhesive tapes separation. We will estimate this irradiation using the generalized diffusion model for non-relativistic electrons.

The radiation-pulse electrical conductivity of polyethylene and polypropylene at a low (about 100 K) temperature under the influence of electron pulses with an energy of 50 keV with a duration of 1 ms has been studied. The Rose–Fowler–Weisberg model was used to explain the results. It is shown that when using it, it is necessary ...

The work is devoted to the development accelerometer for measurement of fast movements in laboratory experiment. In our previous experiments on the slider model of a seismogenic fault, it was revealed that the use of single sensitive acceleration sensor does not allow for qualitative and quantitative characterization of all observed movements. The high-amplitude movements could ...

Experimental modeling of physical processes associated with faults of the Earth's crust is important for studying earthquakes, rock burst and processes accompanying the deposit development. Laboratory experiments with the study of stick-slip sliding of rock blocks relative to each other on a fault slider model have become widespread. Stick-slip sliding manifests itself in the form ...

Despite the development of numerous advanced ligands for Pd-catalyzed Suzuki cross-coupling reaction, the potential of (oligo)peptides serving as ligands remains unexplored. This study demonstrates via density functional theory (DFT) modeling that (oligo)peptide ligands can drive superior activity compared to classic phosphines in these reactions. The utilization of natural amino acids such as Met, SeMet, and ...

A numerical simulation of a positive streamer in long (up to 3 m) air gaps under normal conditions was performed within the 1.5D model taking into account the ionization expansion of the channel. It is shown that the average electric field in the channel and the field required to bridge the discharge gap are not ...

Optically pumped InAs quantum dot microdisk lasers with grooves etched on their surface by a focused ion beam are studied. It is shown that the radial grooves, depending on their length, suppress the lasing of specific radial modes of the microdisk. Total suppression of all radial modes, except for the fundamental radial one, is also ...

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 ...

Abstract
In this paper, I address the problem of generation and destruction in Spinoza’s philosophical system. I approach this problem by providing an account of how Spinoza can maintain that contrary finite modes cannot inhere in the same substance, while substance itself does not change. One must distinguish between the formal essence of a mode and ...
