Data on all known currently trematodes, revealed in insectivores and muride rodents from the Middle Volga region are generalised and analysed in article. The description and original drawings of 10 parasites species are given. 2 helminth species (Brachylecithum rodentini, Corrigia vitta) were specified for micromammals from Volga basin for the first time.… (More)
Ecological analysis of the helminthofauna of common shrew Sorex araneus L. from Samarskaya Luka (Samara Region) has been carried out. Twenty-three helminth species are found including 3 species of trematodes, 8 cestodes, 10 nematodes, and 2 acanthocephales. Dependence of the structure of helminthofauna on the host age is revealed.
The observed strong dark-to-luminous matter coupling is described by a bias relation between visible and dark matter sources. We discuss the bias which emerges in the case where the topological structure of the Universe at very large distances does not match properly that of the Friedman space. With the use of such " topological " bias, we construct the… (More)
We present an extension of the field theory onto the case in which the topol-ogy of space can vary. We show that the nontrivial topology of space displays itself in a multivalued nature of all observable fields and the number of fields becomes an additional degree of freedom. In the limit in which topology changes are suppressed, the number of fields is… (More)

We derive a " generic " inhomogeneous " bridge " solution for a cosmological model in the presence of a real self-interacting scalar field. This solution connects a Kasner-like regime to an inflationary stage of evolution and therefore provides a dynamical mechanism for the quasi-isotropization of the universe. In the framework of a standard… (More)
In 70's A.A. Kirillov interpreted the (stationary) Schrödinger or Sturm-Liouville operator L 2 = d 2 dx 2 + F as an element of the dual spacê g * tô g = vir, the Virasoro algebra ; he also interpreted the (stationary) KdV operator L 3 = d 3 dx 3 + d dx F + F d dx in terms of the stabilizer of L 2 and found a supersymmetry that connects solutions of L 3 f =… (More)
The influence of vector fields on the origin of classical space in quantum cosmologies and on a possible compactification process in multidimensional gravity is investigated. It is shown that all general features of the transition between the classical and quantum evolution regimes can be obtained within the simplest Bianchi-I model for an arbitrary number… (More)
