Correlation between variations in the flux of galactic cosmic rays and variations in solar activity factors and interplanetary medium parameters during minima of even cycles of solar activity
Correlation between variations in the flux of galactic cosmic rays and variations in solar activity factors and interplanetary medium parameters during minima of even cycles of solar activity
S.N. Kuznetsov, I.N. Myagkova
The correlation between the fluxes of galactic cosmic rays (GCR) and the number of solar spots decreased during the minima of the last two even solar activity cycles, but persistent correlation existed between the GCR fluxes and the modulus of the Sun's magnetic field and the solar wind velocity, which is probably associated with a decisive influence of the high-speed solar wind that flows from polar coronal holes on the properties of the interplanetary medium in these periods.

The spectra of photoabsorption of a trial electromagnetic radiation by a magnesium atom in the vicinity of the $3p^2\ ^1S$ autoionization state { AIS) have been calculated in the resonance approximation. The $3p{^2\ ^1}S$ AIS is connected with the $3p3d\ ^1P$ state by a strong laser field. A qualitative agreement has been obtained with the measured ion yield in two-photon ionization of magnesium vapors by bichromatic laser radiation for various laser frequency values.

It has been obtained experimentally that the dynamic characteristics of water and some DNA components are additive. The M$\stackrel{..}{o}$ssbauer parameters $f_R$ and ${<}u^2{>}$ have been found for the "spiral-tangle" transition that accompanies DNA denaturation.

Обсуждается возможность физического обоснования появления электромагнитных предвестников сильных землетрясений и описан исследовательский измерительно-вычислительный комплекс для мониторинга таких предвестников. Исследованы изменения электродинамических параметров ионосферы, вызывающие изменение амплитуды принимаемых радиосигналов на сверхдлинноволновых радиотрассах, усиление собственной волновой структуры $F2$-слоя и образование спорадического $E_s$-слоя (экранирующий эффект) в ионосфере.

Изучено влияние неоднородности магнитного поля нМП (в пределах 300 мкТл) на обучение крыс. Негативный эффект проявился в неспособности крыс самостоятельно обучаться, а позитивный - в ускорении переработки информации. При этом сформированное поведение было крайне неустойчивым с признаками психоэмоционального перенапряжения. Предполагается, что нМП приводит к рассогласованию между заданным уровнем когнитивной деятельности и физиолого-биохимическими возможностями реализующего субстрата.

Numerical experiments were carried out with a mathematical model describing the planetary distribution of the radio emission stream coming from groundbased radio stations of the SW band. The fractions of energy absorbed by the ionosphere, absorbed by the Earth surface, and emitted into space were determined as functions of the season and universal time.

Diurnal and weekly variations of peroxy radical concentration due to varying industrial load in Moscow

Concentrations of some minor gas components were measured in Moscow in the winter-spring period of 1996. The dynamics of peroxy radical concentrations was evaluated on the basis of a one-dimensional photochemical model, taking into account the variable insolation, which depends on the cloud cover and the level of urban atmosphere pollution. Diurnal and weekly periods were found in the concentration behavior. They are associated with the city's industrial rhythm. The total concentration of peroxy radicals can serve as an air purity indicator.

The altitude-time distribution of ozone in the stratosphere and mesosphere over the Moscow region was studied with the aid of a radio spectrometer operating in the 2-mm wave band in the period from January 1996 to May 1997. A significant reduction in the relative concentration of ozone was discovered at the altitudes of 30 to 40 km in winter periods.

The contemporary state of tsunami research for the Black Sea is reviewed. General physical and geographical parameters of historical tsunamis are summarized based on tide-gauge observations and verbal descriptions. Probable source zones of catastrophic waves were located. Physical patterns of tsunami propagation in the open sea and in the shelf zone were derived by numerical modeling.
