By dilatometric method rate of polymerization and the polymerization effective constant determined. Using the inhibitory method the initiating rate constant has been determined. Making use our own experimental results and recent literature data the chain propagation and termination, rate constants have been determined at 323 K.

In this article theoretical studies of DESO–H₂O molecular complexes by ab initio quantum-chemical calculation is presented. From the vibrational spectroscopic studies of diethylsulfoxide water solutions the possibility of formation of DES0–H₂O(I) and DESO–H₂O(II) complexes is developed. By ab inintio quantum-chemical calculations the existence of these complexes is confirmed. By means of Gaussian 98 computer program the structure, energetical features and theoretical vibrational frequencies of the complexes is calculated.

The peculiarities of the N-imidazole sorption on the smooth platinum electrode have been studied in the 0–3.0 V potentials range by means of the fast potentiodinamic impulses method. The two characteristic fields of the sorption have been observed for imidazole: the first – destructive sorption field on the namely platinum electrode within the 0–1.25 V potentials range (maximal values under 0.4 V), and sorption on the PtO₂ oxide layer under higher anodic potentials (maximal values under ~2.3 V).

The interaction of analginum anion with dye of triphenilmethane raw malachite green has been studied. Formed ionic associate could be extracted once through (R = 0.966) by dichlorethane-toluene (1:1) binary mixture. The extracts of ionic associate are submitted with the main law of spectrophotometer in the 1.67–26.7 mcg/mL range of analginum contents (ε = 5.5 ·10⁴ ± 500 (L·mol^-1·cm^-1)). The molar ratio between analginum and malachite green in ionic associate is 1:1. The elaborated method has been applied for determination of analginum in spasmalgonum, baralgetase and pentalgin-H

It has been approved according to the experimental research results, that after insecticide BT(NAR)-3, BT(NAR)-7, BTB, Lepidocide bacterial insecticides do not have negative influence on the qualitative and quantitative composition of bacterium (spurious and non-spurious) ammonium creating of light brown and gray semi desert of apple orchards, which provides the opportunity of broad application of insecticides against the above mentioned phyto fagan.

In the oxygen deficiency conditions we studied influence of irritation of Locus Coeruleus (LC) stimulation on the impulse activity of the reticular neurons and on the respiration. Phases of hypoxia were the model of experiment. At the initial stage of hypoxia (4000-5000 m higher) the frequency of reticular neurons was growing. Against this background the facilitating influence of stimulation of LC was less prominent, though it prevailed over its inhibiting action. At the maximal altitude (7500-8000 m higher) however, the frequency of stimulus was falling, and mainly the facilitating effect of stimulation of LC was continuing. The rats after being brought back to the normal atmospheric pressure displayed gradual recovery of initial exponents with respect to both the spontaneous rhythmic activity of neurons and the reactions to stimulation. Those different reactions of irritation LC have regulation sense on respiratory neurons.

Parameters of heart rhythm variability of the examinees with different level of extraversion during creative task performance were investigated. Reduction of die stress index value at examinees-introverts is revealed, which testifying about intensification of parasimpathic influence of vegetative nervous system is revealed. Unlike them at examinees-extraverts parasimpathic effect is not observed.

The genesis of mini- and microsatellite loci, which is under extensive study in humans and some other bisexual species, have been virtually overlooked in clonal mode of reproduction. In present study we use PCR-analysis to examine allelic polymorphism of two loci of D. dahli – Du 215 and Du 281-containing (GATA)_n microsatellite cluster. Different levels of intrapopuliation and interpopuliation variability of these loci were found. Du 215 showed the highest polymorphism – 8 allelic variants. Three alleles were found for Du 281. The primers chosen for loci Du 215 and Du 281 were also used for PCR analysis of homologous loci in two presumptive parental bisexual species D. mixta and D. portschinski. The PCR products of the corresponding loci of the parental species had approximately the same size. These data on the structure of the DNA loci provide a possibility to study genetic diversity in the parthenogenetic species D. dahli.

In the article is estimated climatic conditions influencing on productivity of cultivated cultures using in soil bonitiration and earth cadastre composition. It is given an account of determination of methodical approach of contribution of climatic factors on crop capacity, which will let us determine high borders of ecological optimum of cultivated agricultural cultures.

Interaction of pentaiodoplatinate (IV) with thiazine raw organic basic dye thionine in sulfuric acid environment has been studied. The optimal conditions for the formation of ionic associate (IA) and its extraction in organic phase, also concentration of dye, the range of platinum (IV) content,selectivity of extraction are determined. The content of IA is determined.

Matsun samples from different regions of Armenia were collected. Lactic acid bacteria belonging to genus Lactobacillus and Streptococcus were isolated and studied. Their high antibacterial activity against gram-positive and gram-negative bacteria has been shown.
