How Disorder Originates and Grows Inside Order

S. E. Kurushina, E. A. Shapovalova

Journal of Statistical Physics > 2019 > 176 > 1 > 69-84

We present a study of disorder origination and growth inside an ordered phase processes induced by the presence of multiplicative noise within mean-field approximation. Our research is based on the study of solutions of the nonlinear self-consistent Fokker-Planck equation for a stochastic spatially extended model of a chemical reaction. We carried out numerical simulation of the probability distribution...

R. I. Khusainova, A. V. Tyurin, D. A. Shapovalova, E. K. Khusnutdinova

Russian Journal of Genetics > 2017 > 53 > 7 > 785-794

We conducted an association study of ten polymorphisms in six candidate genes of OA (rs1799750 (MMP1), rs35068180 (MMP3), rs2252070 (MMP13), rs63118460 and rs2276455 (COL2A1), rs143383 (GDF5), rs1544410, rs7975232, rs731236, and rs2228570 (VDR)) with the development of osteoarthritis (OA) in 333 women taking into account the localization of the pathological process, the age of disease manifestation,...

Variable Intensities of Molecular Features in the Spectrum of AE Aur

J. Krełowski, G. A. Galazutdinov, G. Mulas, A. Bondar, more

Acta Astronomica > 2016 > Vol. 66, No. 3 > 391--403

Using spectra of the star AE Aur (HD 34078), covering the period 1997-2015, we suggest that two strong molecular features of CH and CH+ underwent detectable changes of intensity. In the last five years both CH and CH+ declined sharply and systematically, with the CH/CH+ ratio steadily growing. No variations in the radial velocities of the observed interstellar features was detected during the covered...

Methods coagulation/flocculation and flocculation with ballast agent for effective harvesting of microalgae

Kirill V. Gorin, Yana E. Sergeeva, Victor V. Butylin, Anastasiya V. Komova, more

Bioresource Technology > 2015 > 193 > C > 178-184

The effects of coagulant (FeCl₃·6H₂O), various flocculants based on polyacrylamide (PAA), polyethylenoxide (PEO) and flocculated biomass as ballast agent, dosage and sedimental time on flocculation efficiency of harvesting Chlorella vulgaris GKV1 cultivated in a laboratory were investigated. The results of this work indicated that the flocculation efficiency achieved about 90% after 5min of sedimentation...

Importance of the Pharmacokinetics of Valproic Acid in an Individualized Approach to the Treatment of Epileptic Women of Fertile Age

N. A. Shnaider, D. A. Sychev, M. S. Pilyugina, D. V. Dmitrenko, more

Neuroscience and Behavioral Physiology > 2012 > 42 > 9 > 963-968

A clinical case of the development of therapeutic side effects in an epileptic woman of childbearing age is presented. The development of therapeutic side effects occurred on the background of an intermediate therapeutic dose of a valproic acid formulation and was associated with primary (idiopathic) and secondary (valproate-induced) impairments to the folate cycle on the background of a combination...

Study of tribological behavior of metal-ceramic friction material MK-5 obtained by freely spread layer technique for hydromechanic transmissions

A. F. Il’yushchenko, A. V. Leshok, O. A. Shapovalova

Journal of Friction and Wear > 2012 > 33 > 5 > 365-370

The tribological behavior of a metal-ceramic friction material for hydromechanical transmissions of heavy-duty transport vehicles is studied. It is shown that the average wear of the driven plates after the tests simulating mean loading conditions of clutches is 0.025 mm (with permissible 0.06 mm) and the wear of drive plates is 0.0247 mm (with permissible 0.05 mm). The tests of a retarder brake show...

Results of testing of frictional discs for hydromechanical transmissions of BelAZ dumpers made of various materials

A. F. Ilyushchenko, A. A. Dmitrovich, O. A. Shapovalova, V. V. Reginya, more

Journal of Friction and Wear > 2011 > 32 > 3 > 179-185

The paper deals with assessment of the performance of metal-ceramic frictional materials from various manufacturers applied in a hydromechanical transmission of mine dumpers produced by the Belarus Automotive Plant. Studies of the behavior of frictional discs of different materials on a ULIS inertia workbench show that the MK-5 frictional material and the material produced by Wellman Co. are the most...

Utilization of arylaliphatic nitriles by haloalkaliphilic Halomonas nitrilicus sp. nov. isolated from soda soils

A. Chmura, A. A. Shapovalova, S. Pelt, F. Rantwijk, more

Applied Microbiology and Biotechnology > 2008 > 81 > 2 > 371-378

An enrichment culture from saline soda soils, using acetate as carbon and energy source and 2-phenylpropionitrile as nitrogen source (PPN) at pH 10, resulted in the isolation of strain ANL-αCH3. The strain was identified as a representative of the genus Halomonas in the Gammaproteobacteria. The bacterium was capable of PPN utilization as a nitrogen source only, while phenylacetonitrile (PAN) served...

Heterotrophic denitrification at extremely high salt and pH by haloalkaliphilic Gammaproteobacteria from hypersaline soda lakes

A. A. Shapovalova, T. V. Khijniak, T. P. Tourova, G. Muyzer, more

Extremophiles > 2008 > 12 > 5 > 619-625

In this paper we describe denitrification at extremely high salt and pH in sediments from hypersaline alkaline soda lakes and soda soils. Experiments with sediment slurries demonstrated the presence of acetate-utilizing denitrifying populations active at in situ conditions. Anaerobic enrichment cultures at pH 10 and 4 M total Na⁺ with acetate as electron donor and nitrate, nitrite and N₂O as electron...
