Turbulent plane Couette flow with wall-transpiration
No full textIn the present abstract, DNS results obtained for turbulent plane Couette flow with wall-normal transpiration velocity are presented. Important equations valid in such a flow are derived, describing the total shear stress and the relation between the friction velocities at the lower and upper wall. These expressions are of importance, as there are neither experimental nor DNS data to compare with. Equally important, we derive a center region and a viscous sublayer velocity scaling for the suction wall, which were both validated using the DNS data

Glaucoma is still one of the leading causes of the blindness and low vision. According to the World Health Organization, an estimated number of glaucoma patients is 60.5 to 105 million and is growing steadily. In many highly developed countries, glaucoma accounts for 13–28% of blindness. High intraocular pressure (IOP) is the most important risk factor for glaucomatous optic neuropathy and low vision in primary open-angle glaucoma (POAG). It was demonstrated that IOP lowering to the individual tolerant level in POAG preserves vision for a long time.
The paper discusses potential adoption of of the software for the calculation of tolerant IOP in POAG. Tolerant IOP calculations will help to adjust treatment in time to achieve individual IOP normal ranges, to predict glaucoma stabilization or progression as well glaucoma progression rate. The algorithm of treatment strategy for POAG is described.
Key words: glaucoma, primary open-angle glaucoma, intraocular pressure, tolerant IOP, glaucomatous optic neuropathy, prostaglandin analogue, latanoprost, Trilactan.

A D-band (130 GHz) EPR study of the primary electron donor triplet state in photosynthetic reaction centers of Rhodobacter sphaeroides R26
No full textA high-field (D-band, 130 GHz) electron spin echo-detected spectrum of the primary electron donor triplet state, P-3, in quinone-depleted photosynthetic reaction centers from the bacterium Rhodobacter sphaeroides R26 is obtained. It shows a significant g-anisotropy, which is larger than that of the primary donor oxidized state, P+. Simulation gives the triplet g-tensor principal values of 2.0037, 2.0028, and 2.0022 (precision +/-0.0001), assuming that the g-tensor is coaxial to a zerofield splitting tensor. The P-3 spectral lineshape reveals an orientational anisotropy of the triplet quantum yield. We explain this anisotropy as arising from the difference in the main values and relative orientations between the g-tensors of P+ and I-A(-.) in the primary radical pair (the triplet state's precursor)

Ivanovo State University of Chemistry and Technology, Inanovo, Russian FederationВ статье рассматривается проблема терминологического аппарата участников коммуникативного события. Автором анализируются различные классификации, которые основаны на роли и характерологических особенностях адресата и адресанта в коммуникативном акте. Внимание уделяется массмедийной среде, в которой выделяется структурно осложненное образование – продуцент и созданный им «эскиз аудитории», включающий целевого и потенциально целевого
адресатов. Данная классификация ориентирована на выявление мотивационной установки и функциональной направленности речевого акта. The article considers the problem of the terminological apparatus for the communicative event participants. The author analyzes various classifications based on the role and characterological features of an addressee and an addresser in a communicative act. Attention is paid to mass media, where a complex formation is distinguished, comprising the producer and the created by him “audience sketch”, including a target recipient and a potential target recipient. Thе classification involved focuses on identifying the motivational attitude and functional orientation of the speech act
