Summary.
The objective. 1. To analyze both domestic and foreign articles published and study the posibbilities to use mifepristone as a blocker of progesterone receptors in a daily gynecological and obstetrical practice. 2. To elect optimal doses of mifepristone used to the treatment of different gynecological states. Materials and Methods. Literary sources for 1992-2018 concerning preventive and therapeutic use of mifepristone. Results. Mifepristone is a progesterone receptor antagonist that has also antagonistic properties to glycocorticoids, mineralocorticoids and androgen receptors. Single use of mifepristone in dose 600 mg combined with low doses of prostaglandins is an effective medical abortion remedy in I and II trimesters of pregnancy. In the III trimester it can be used once or twice with interval of 24 hours to stimulate contractions of uterus and start the process of childbirth. As an emergency contraceptive agent mifepristone can be used in a dose 10 mg. 3-6 months of 50 mg/day. It can reduce the size of leiomyoma by 50-74%. To treat endometriosis and breast neoplasies miferinone can also be used in combined schemes. However, doses are not defined and vary from 2.5 to 200 mg/day. Amenorrhea is the most common side effect of mifepristone use that appears in nearly 100% of cases independently of applied doses. Conclusions. Mifepristone is an effective anti- gestagene medication that can be used for acute contraception, artificial termination of pregnancy in I and II trimesters, stimulation of childbirth in III trimester, treatment of leiomyoma, endometriosis and breast neoplasy in doses that vary from 5 to 600 mg according to the objectives.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Analysis of the Shape of Wave Packets in the “Half Space–Layer–Layer with Rigid Lid " Three-Layer Hydrodynamic System
No full textLunyova M. V. Analysis of the Shape of Wave Packets in the “Half Space–Layer–Layer with Rigid Lid " Three-Layer Hydrodynamic System / O. V. Avramenko , M. V. Lunyova // Journal of Mathematical Sciences. 2022. - Р. 147-165. URL: https://doi.org/10.1007/s10958-022-05914-9(ua) We study the process of propagation of weakly nonlinear wave packets on the contact surfaces of a “half space–layer–layer with rigid lid” hydrodynamic system by the method of multiscale expansions. The solutions of the weakly nonlinear problem are obtained in the second approximation. The condition of solvability of this problem is established. For each frequency of the wave packet, we construct the domains of sign constancy for the coefficient for the second harmonic on the bottom and top contact surfaces. The regularities of wave formation are determined depending on the geometric and physical parameters of the hydrodynamic system. We also analyze the plots of the shapes of deviations of the bottom and top contact surfaces typical of the constructed domains of sign-constancy of the coefficient. We discover the domains where the waves become ∪ - and ∩ -shaped and reveal a significant influence of wavelength on the shapes of deviations of the contact surfaces of the analyzed hydrodynamic system
The role of the bile salt surfactant sodium deoxycholate in aqueous two-phase separation of single-wall carbon nanotubes revealed by systematic parameter variations
Get PDFAqueous two-phase (ATP) extraction has been demonstrated as a fast, scalable, and effective separation technique to sort single-wall carbon nanotubes (SWCNTs) according to their diameter and chiral structure. The exact mechanism behind the chirality-dependent migration of SWCNTs between the two phases is however not completely understood, and depends on many parameters (e.g., choice of surfactants and their concentration, pH, temperature, ...), making it difficult to optimize the multivariable parameter space. In this work, we present a systematic study of the choice and concentration of specific surfactants on the ATP sorting, by performing a series of single-step ATP separations in which each time only one parameter is systematically varied, while monitoring the structure-specific migration of every SWCNT chirality between both phases with detailed wavelength-dependent spectroscopy. These systematic studies reveal that the diameter-dependent stacking of a discrete number of sodium deoxycholate molecules fitting around the SWCNT circumference determines the separation order in the form of a periodically modulated pattern as a function of SWCNT diameter. Addition of cosurfactants can be used to compete with the bile salt surfactant to enhance the separation yields, but does not affect the sorting order. The results are afterwards directly applied to predict the parameters required to separate specific chiral structures in just two ATP steps
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Get PDFFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
