Opis:: The dynamics of emission of heavy metals compounds into the air in Vinnytsia region (Ukraine) in 2003-2010 years is analyzed. The level of pollution for compounds of some heavy metals (Cd, Hg) has arisen, for others – has decreased (Pb, Cr) or has not changed (As, Ni). The sources of such pollution are defined according to the amount of the emissions of heavy metals compounds in different sectors of economy. In Vinnytsia region they include transport, industrial plants and municipal sector. Great quantity of transport and hazardous materials are consdered as the reasons of increasing of heavy metals emissions. Usage of more environment friendly resources (e.g. unleaded gasoline, natural gas instead of coal) is defined as the reason of reduction of heavy metals emission.

Opis:: The point-contact Andreev-reflection measurements on the new paramagnetic superconductor $Mo_3Sb_7$ were carried out. It was found that the order parameter ∆ is strongly anisotropic varying over a very wide range depending on the contact orientation when the maximum $∆_\text{max}$ exceeds at least 40 times the minimum $∆_\text{min}$ in spite of the invariable $T_c$ that cannot be typical of conventional superconductors. For these and other reasons we suggest that $Mo_3Sb_7$ is not a trivial BCS (s-wave) superconductor but rather has some unconventional pairing symmetry.

Opis:: In this work for the first time we give the evidence that compound $Dy_{1-x}Y_x Rh_4B_4$ with the tetragonal body-centered crystal structure $LuRu_4B_4$ is the ferrimagnetic at temperatures $T_{Cur}$<40 K, ferrimagnetic superconductor at $T_C$ <10 K and antiferromagnetic superconductor at $T_N$ <3 K. No reentrant behavior was found down to T = 0.32 K. For the first time by means of a method of microcontact spectroscopy of the Andreev reflection in point contact$ Ag-Dy_{0.8}Y_{0.2}Rh_4B_4$ the value and temperature and field dependences of superconducting gap parameter∆(T, H) in $Dy_{0.8}Y_{0.2}Rh_4B_4$ were determined. The value of the ratio 2∆(0)/k$T_C$ is about 4. Some unusual features of∆(T, H) dependences were observed, which give the evidence that the $Dy_{1-x}Y_xRh_4B_4$ is a candidate for spin-triplet Cooper pairing of charges with the parallel spins.
