THE QUANTITATIVE ANALYSIS OF ORBITS EVOLUTION OF GIANT PLANETS AND TRANS-NEPTUNIAN OBJECTS DURING THE RED GIANT ERA OF THE SUN
Abstract
The quantitative analysis of orbits evolution of giant planets and some trans-neptunian objects during the red giant era of the Sun in approach circular and elliptic orbits is done in this work. In particular, obvious analytical dependences of Kepler elements from relative change of Sun mass () are presented here. The corresponding numerical values for specified bodies on the four eras beginnings of the Sun life are calculated. Comparison with predecessors results is carried out. It is shown that on the beginning of white dwarf era only giant planets and two large trans-neptunian objects: Kvavar and Varuna have chance of existence in Solar system. Other celestial bodies will have left Solar system.

HYPOTHESIS OF THE EXISTENCE OF NEMESIS AND TYCHE. I. BASIC PHYSICAL BODIES PROPERTIES
Abstract
In this work the hypothesis of existence of massive dark body (in cases of brown dwarf (Nemesis) and gas giant (Tyche)) in the Solar system periphery is reasoned. Basic physical properties and orbital characteristics of these bodies are considered. The solution of the problem on denition of scattering an- gle of photon in gravitational eld of spherical microlens is submitted. It is shown that today the required value for these bodies can be measured in experiment. Dimensionless analytical results for differential and total cross sections of photons scattering in gravitational eld of microlens are represented. The problem of «ghosts» formation by gravitational microlens is solved. It is demonstrated that in most cases of the close rapprochement of source and lenses (Nemesis, Tyche) on experiment it is possible to detected two «ghosts». It is one of the main arguments in favor of the method efficiency in search of dark massive objects in the Solar system.

HYPOTHESIS OF THE EXISTENCE OF NEMESIS AND TYCHE. II. USING OF THE GRAVITATIONAL LENSING METHOD FOR ASSESSMENT OF THEIR DETECTING PROBABILITY
Abstract
In this work the analysis of photometry of microlensing (background star of the Galaxy) pheno- menon by massive dark body on the Solar system periphery is done. The total light ux and coefficient( A ) of brightness strengthening of background star are calculated. The formula for microlensing time ( T 0) is received. It is shown that most favorable conditions for Nemesis and Tyche microlensing are realized in the scenario with maximal values of their masses in the vicinity of the perihelion. So for Nemesis A < 10,3 and microlensing time T 0 = 26-68 days, for Tyche A < 2,1 and microlensing time T 0 = 4,8-5,4 days. Specied intervals of the given values are experimentally achievable today. The assessment of probability of Nemesis and Tyche detecting is found. For telescopes with limiting magnitude 16m maximum proba- bility of the microlens phenomenon detecting doesn’t surpass for Nemesis 10-5 and for Tyche 8·10-6. However, if there are globular or open star clusters behind Nemesis or Tyche the probability can be (10-2).

INFLUENCE OF THE HYDROCHLORIDE 4-(2-METHYL-1Н-IMIDAZOL-1- YL-METHYL)-BENZOIC ACIDS AND ITS PRECURSORS ON THE FUNCTIONAL CONDITION OF RATS HEART
Abstract
In the present work, presented the results of experiments, in which influence of solutions of a hydrochloride 4-(2-methyl-1H-imidazol-1-yl-methyl)-benzoic acids and its precursors (imidazole and benzoic acid) on a functional condition of rat heart was studied. The parametres of the electrocardiogram like size of waves P, R, duration of intervals R-R, P-Q, Q-T, complex QRS, and heart rate were studied.

ASSESSMENT OF VULPINIC ACIDS CYTOTOXICITY
Abstract
The article says results of evaluation of the cytotoxicity effect of the secondary metabolite lichen Vulpicida pinastri vulpinic acid using Аllium-test. Shows the ability vulpinic acid in concentrations 0,0275; 0055; 0,11 mg/ml to inhibit pullulation seeds, proliferative activity in cells of the root meristem, represented by a mitotic index decrease. Blocking of mitosis at impact high concentration of vulpinic ac- id at the stage of prophase, in much lower concentrations at the stages of anaphase and telophase.

VALUE AS AN INDICATOR OF CHANGES IN THE INDICES OF THE LEAVES IN DIFFERENT GROWING PERIODS
Abstract
In this article analyzing the material, obtained during the study of leaf samples of pear varieties and strawberry Samara’s selection. The comparison of phytomass data from three different favorable levels for fruit growing seasons (2012, 2013 and 2014 years) is done. Conservation under stressful conditions structural and functional parameters of pear and strawberry leaves at the level of norms (favorable growing period) or fractional increase of them is seen as evidence of the stability of pear and strawberry varieties under local conditions of cultivation.
