Ionizational instability in an ionized inert gas flowing in a magnetic field.

We discuss the evolution of ionization instability, which gives rise to the formation of regular structures in plasma. The experiment was conducted in a disk magnetohydrodynamic channel in Xe. The evolution of luminous inhomogeneities, and changes in the luminosities of individual inhomogeneities, are traced.

[On clinical manifestations of rotavirus-related gastroenteritis and possible links with its viral phoretype].

The results are presented of the study of rotavirus gastroenteritis course in 45 patients (23 children and 22 adults) with different phoretypes. Phoretypical heterogeneity of rotavirus population was discovered among which the "long" phoretype prevailed. Rotavirus infection ran with diverse clinical symptoms: mild, moderate and severe.

[Virus carriers in rotavirus infection].

Discusses the effects of various factors on the expression of asymptomatic virus carriership and validates the need in laboratory screening of risk groups including children aged under 5 years and elderly subjects aged over 60. During outbreaks of rotaviral infection virus carriership among healthy subjects may be as high as 34.6%.
