A question about the environmental safety of the nano world, as well as some aspects of the development of safety standards nanomaterials.
We investigate numerical solutions of linear ordinary and partial differential equations. Cauchy’s problem for ordinary equations of first and second order are generalized with fractional power of finite operator. Condition of regularization for the difference operator analogue of a fractional power is represented
The paper presents one of the possible mechanisms of formation and decay of the ring current
The results of Ionosonde data over Kamchatka during the emergence of D-layer at night are discussed. At the same time, the spectra of the night sky are represented at this period using a spectrum analyzer installed on Lidar Station of IKIR FEB RAS
On the example of the local powergrid of Kamchatka shows the relationship between the magnitude of industrial current harmonics and variations of Earth’s magnetic field. Shows dependence of mechanism of geomagnetically induced currents creation from topology of powergrid.
ИСПОЛЬЗОВАНИЕ СОБСТВЕННЫХ МОД КОЛЕБАНИЙ ВЯЗКОЙ ВРАЩАЮЩЕЙСЯ ЖИДКОСТИ В ЗАДАЧЕ КРУПНОМАСШТАБНОГО ДИНАМОГ.М. Водинчар & G.M. Vodinchar
Considered a model of large-scale magneto-convection in a roteting spherical shell. Velocity expressed of the one of the modes of free oscillation of a viscous conduction fluid in the shell. The stationary modes of convection were found. An ability of the dynamo was approved in this model.
The paper presents the results of numerical modeling of phase trajectories of the dynamical system Rikitake. Parameters of system and initial conditions at the case of doubling cascade mode are showen.
Рассмотрена модель субдиффузии радона без адвекции. С помощью функции Грина найдено решение модели. Показано,что оно является обобщением ранее известного классического решения.
In this paper we study the nonlocal effects of plastic deformation (shear) flow in the subduction zone of the Kuril-Kamchatka arc based on a statistical model cite APS, constructed according to the catalog of seismic moment tensor cite GCMT for the period 1976 - 2005.
The sttatistical relationship between whistlers in Kamchatka and thunderstorm activity was studied. Possibility of impact HAARP on stream of whistlers analyzed.
