    Geochemical specifics of lake water of the Kulunda Steppe territory (Altay region, Russia) are studied. The results show that in the territory mainly chloride and less soda lakes with sodium compound are developed. It is presented that calcite and soda saturation indexes (SI) of lake water increase with growth of pH, but decrease in such minerals as gypsum and barite. The opposite situation is typical for SI depending on the salinity. It is revealed that evaporation, secondary mineral formation and various biological processes have the greatest impact on accumulation of elements in solution

    The chemical composition of nitric thermal waters in Jiangxi Province, SE-China, is considered. It is shown that the studied thermal waters are characterized by low TDS (293-412 mg/l), but they always have alkaline or highly alkaline pH values. It should be noted that the content of Na{+}, Si, F{-}, HCO[3]{-}, CO[3]{2-}, sometimes SO[4]{2-} is predominant, on the other hand, the content of Ca{2+}, Mg{2+}, Cl{-} is low. It has been established that the main factors responsible for low concentrations of some chemical elements and high concentrations of others are continuous dissolution of aluminosilicate minerals and simultaneous precipitation of the secondary minerals

    About the Electron Charge Accelerated in the Small-size Betatron MIB-4

    It is assumed that the electron charge accelerated in small-size betatons is of the same order as that in the classical betatron. However, the parameters of the interpolar space of small-size betatons significantly differ from the parameters of the classical betatron. We can expect that the value of the accelerated electron charge will be different. The paper presents the results of the measurements of the electron charge accelerated in a small-size betatron MIB-4. It is shown that the electron charge accelerated is this betatron is larger than that in the classical betatron

    NASA is developing safe, high energy and high capacity lithium-ion cell designs and batteries for future missions under NASAs Advanced Space Power System (ASPS) project. Advanced cell components, such as high specific capacity silicon anodes and low-flammable electrolytes have been developed for improving the cell specific energy and enhancing safety. To advance the technology readiness level, we have developed large-format flight-type hermetically sealed battery cells by incorporating high capacity silicon anodes, commercially available lithium nickel, cobalt, aluminum oxide (NCA) cathodes, and low-flammable electrolytes. In this report, we will present the performance results of these various battery cells. In addition, we will also discuss the post-test cell analysis results as well

    Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron

    The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of s=1.96\sqrt s =1.96 TeV. We report the results of combinations of the inclusive asymmetries and their differential dependencies on relevant kinematic quantities. The combined inclusive asymmetry is AFBttˉ=0.128±0.025A_{\mathrm{FB}}^{t\bar{t}} = 0.128 \pm 0.025. The combined inclusive and differential asymmetries are consistent with recent standard model predictions

    In the existing conditions in various companies, it is possible to observe an increase in the complexity of automation of many processes. Therefore, there is a need for distributed automated systems. They are required to operate under the constraints of real-time control and communication in manufacturing processes. In cyber-physical systems, a fully synergistic integration of control computation with physical devices and processes is implied. In addition, the incorporation of a cyber-physical system into automated plant systems will provide opportunities for unifying automated process control. Due to the automated control of production and enterprise as a whole, it is possible to form a controlled system, from order to realization. It is proposed to form a training and research system to work with cyber-physical system. Intelligent support for specialists within cyber-physical systems is associated with corresponding performance requirements. An illustration of a schematic of a training and research system for personnel management in a cyber-physical system is presented. A schematic of the training subsystem is shown. Instrumental examination within the research subsystem provides opportunities to realize the creation of an information support structure. An illustration of the schematic diagram of the analysis research subsystem is presented. A structure for conducting automated modeling of processes within a cyber-physical system is shown
