On Properties of the Intrinsic Geometry of Submanifolds in a Riemannian Manifold

In the paper we study the properties of a metric function which is the extension by continuity of the intrinsic metric of the interior of a submanifold to its boundary. This approach is the development of the classical intrinsic geometry of surfaces studied by A.D. Alexandrov and his school

On the Mass Eigenstate Composition of the 8B Neutrinos from the Sun

The present data of gallium experiments provide indirectly the only experimental limit on the fraction of $\nu_2$ mass eigenstate for the $^8$B neutrinos from the Sun. However, if to use the experimental data alone, the fraction of $\nu_2$ and, consequently, $sin^2\theta_{sol}$ still is allowed to be varied within a rather broad range. The further experimental efforts are needed to clear this point.Comment: 13 pages, 1 figure, 1 table. Corrected version, published in JCAP04(2007)00

Laboratory Control of the Drinking Water Quality in the Territory of the Jewish Autonomous Region in View of the Flooding in the Far East

Represented is the short characteristic of natural waterways and temporal distribution of atmospheric precipitations in the Jewish autonomous region. Given are the data on the organization and carrying out of monitoring as regards centralized and non-centralized water supply sources and other socially significant water objects in the Jewish Autonomous Region under the conditions of flooding and during the post-flooding period in 2013. Enforced has been control over sanitation of the unorganized water supply sources located in countryside, provision with disinfectant agents along with information distribution regarding essential anti-epidemic measures that are to be taken. Outlined is the total number of the drinking water samples, investigated at the time of a high water period, wherein reasonably high rates of inconsistent indexes has been detected. Thus, the scope of conducted preventive and anti-epidemic actions have made it possible to keep the epidemiological situation in the Jewish Autonomous Region stable

Imaging Three Dimensional Two-particle Correlations for Heavy-Ion Reaction Studies

We report an extension of the source imaging method for analyzing three-dimensional sources from three-dimensional correlations. Our technique consists of expanding the correlation data and the underlying source function in spherical harmonics and inverting the resulting system of one-dimensional integral equations. With this strategy, we can image the source function quickly, even with the finely binned data sets common in three-dimensional analyses.Comment: 13 pages, 11 figures, submitted to Physical Review

A Lithium Experiment in the Program of Solar Neutrino Research

The experiments sensitive to pp-neutrinos from the Sun are very perspective for the precise measurement of a mixing angle $\theta_{12}$. A $\nu$e$^{-}$ scattering experiment (Xmass) and/or a charged-current experiment (the indium detector) can measure the flux of electron pp-neutrinos. One can find the total flux of pp-neutrinos from a luminosity constraint after the contribution of $^7$Be and CNO neutrinos to the total luminosity of the Sun are measured. The radiochemical experiment utilizing a lithium target has the high sensitivity to the CNO neutrinos, thus, it has a good promise for the precise measurement of a mixing angle and for the test of a current theory of the evolution of the stars.Comment: 6 pages, 2 figures, 1 table, A report made by A.Kopylov at International Conference NANP-2005, June 2005, Dubna, Russi
