Estimating the Unit of the Physical Quantity of a Collective Working Standard from the Results of Intragroup Comparisons by Utilizing the Maximum-Likelihood Criterion

A procedure is developed for applying the criterion of maximum likelihood in order to form estimates of the unit of the physical quantity of a collective working standard from the results of mutual comparisons of standard elements.     

Application of Diamond in High Technology

This review focuses on the critical issues and future directions in the application of diamond in high technology. Diamond nuclear radiation detectors, photosensors, photoemitters, spectral windows, active and passive microelectronic components, and microelectromechanical systems are discussed in detail. In Russia, high-technology diamond applications have not yet moved toward the manufacturing stage, even though Russia possesses immense resources of natural diamond and a considerable scientific potential in the field of creating unique synthetic diamonds, polycrystalline and single-crystal diamond films, and diamond-like compounds. We hope that the points raised in this review will provide the impetus for the development of diamond technology in Russia.     

Stability of the ash basicity in coal concentrates

Ash basicity of coal concentrates and factory furnace charges is defined for the long period of time. Four groups of the coal concentrates that are discriminated by value and stability of ash basicity are identified. The basicity of furnace charges is shown to be sometimes nonadditive relative to basicities of components. This should be taken into consideration when basicity of components is used for corrections of composition of furnace charges.
