The developed theoretical model and experimental measurements on reactors VVER-1000 of the Zaporozhye NPP neutron of noise depending on frequency testify about intensive density oscillations of thermal neutrons in neutron multiplying systems with the cool... see more

Physical fundamentals of traveling wave reactor are considered. We show that the condition of existence of nuclear burning soliton-like wave in a neutron-multiplying medium is determined in general by two conditions. The first condition (necessary) is det... see more

This work considers dynamics of non-equilibrium long wave fluctuations in systems of particles interacting with multiplying and capturing media, generated by external stochastic field. General dynamic equations for long wave fluctuations are obtained usin... see more

The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to tim... see more

We address the problem of the origin of heavier and super heavy elements in nature. Believing rapid neutron capture process (r-process) is responsible for synthesis of heavy and super heavy elements in the remnants of supernovae explosions and neutron sta... see more

El artículo aborda la sistematización de los procedimientos escritos para la adición, sustracción y multiplicación en la educación primaria. Partiendo de la teoría de sistema se elabora el concepto de sistema de ejercicios y se argumenta el carácter de si... see more

In East Java, based on the records of the East Java Regional Disaster Management Agency (BPBD), it was noted that from January 1 to March 19, 2021, there have been 258 flood disasters. Eleven of them were flash floods and three tidal floods occurred. Like... see more

Determining land suitability is a preliminary procedure to define and determine land fitness for a given type of production. A suitability analysis performed with inadequate methods will not guarantee a successful or significant process. The current attem... see more

A hyperbolic system with a convex extension is usually transformed in the symmetric form by taking the components of the main field as independent variables. However, the symmetric form can be obtained also in the original independent variables, which may... see more
