Dynamo mechanism for turbulent wave in celestial bodies
It is well known that under cosmic conditions the various modes of plasma turbulence waves (including MHD waves) are easily excited. In this paper we are trying to show that the turbulent wave also generates a...

Correlation between growth pattern in vitro and karyotype of bone marrow cells and prognosis in adult acute nonlymphocytic leukemia
Growth pattern in vitro and karyotype of cultured bone marrow cells were studied in 31 patients with acute nonlymphocytic leukemia. Two different growth patterns were identified: cluster growth (pattern I), an...

Modes of internal motion in three-body systems
We propose an approach to investigate the possible internal motions of three-body quantum-mechanical systems held together by pairwise potentials. The method utilizes the “shape-density” functions which we def...

The two neutrino bursts from SN 1987a and phase transition inside neutron star
A new explanation for the two detected neutrino bursts with an interval of about 4.5 hours is suggested. We propose that the first neutrino burst may have been caused by the collapse of a massive star and the ...
