A total of 3986 active regions are recorded during the 21st Solar Cycle. We define 16(e. g. AR3804, AR4474)of the active regions as the strongest active regions in terms of 4 indicies —sunspot area, index of the X-Ray flares, 10.7cm radio flux and proton event index.
Most significant effect on soil enzyme activities was observed in 0-5 cm soil layer. Compared with buffer and background zones, the cellulase activity in active zone was reduced by 92.8% and 80.0%, respectively.
The microbial activities and enzyme activities in 0～5 cm soil were markedly affected by recreational activities,while,they were not affected prominently in 5～15 cm and 15～25 cm layer soil from control zone and buffer zone,but significantly differed from those in active zone.
The results also showed that microbial and enzyme activities in 5-15cm soil and 15-25cm layer soil from control zone and buffer zone were not affected prominently by recrea-tional activities,but were different prominently from active zone.
Tourism activities also had a significant effect on the total amount of soil microorganisms and the amounts of bacteria, actinomyces and fungi in 0-5 cm soil layer, which were higher in background zone, followed by in buffer zone and active zone.
The deposit is similar in geological setting,distribution patterns of metal elements and REE,sulfur isotopic composition,and fluid inclusion characteristics to the Kuroko type deposit and modern sulfide deposits in some sea floor hydrothermal activity regions.

Analysis of interaction energies and conformation changes for 3 nsec simulation indicates that PGM and enolase do show binding affinity between their near active regions, which is necessary for channeling to occur.
As a result of our consideration, it is beyond question that the physical causes of solar and heliospheric phenomena in October-November 2003 are not exclusively local and do not belong only to the active regions and solar atmosphere above them.
The main characteristics of the corona radio emission above these active regions are measured, allowing us to follow their dynamics during the entire period of their existence on the solar disk with a period of one day.
The properties of the active regions and coronal holes are considered.
RATAN-600 microwave observations of powerful active regions from October 23 to November 5, 2003
An analysis of electron microscopy and cytochemistry studies suggests that the halo as a physiologically active zone is localized at the level of the plant cell plasmalemma.
An essentially nonlinear differential equation determining the law of pressure variation in the active zone of the bearing is derived.
Optimization of the Length of the Active Zone of a Plasma Chemical Reactor
The optimum length of the active zone of a plasma chemical reactor is calculated using a semiempirical approach in terms of a mathematical model of coupled physicochemical and thermophysical processes in the reactor.
Indium arsenide/gallium arsenide structures with vertically coupled quantum dots imbedded in the active zone of a laser diode are investigated by deep-level transient spectroscopy (DLTS), and the capacitance-voltage characteristics are analyzed.
