＜正＞ A temperature range of 400-700℃is the range of formation of different electrically active defects in a Czochralski grown silicon （Cz-Si）: "old" and "new" thermal donors （TDs） and shallow thermal acceptors （TAs） in irradiated silicon [1]. A relation between TA and TD concentrations determines conductivity of annealed samples, in the result, thermal acceptors are found to be more pronounced in the Float- zone silicon than in Cz-Si. TAs are often not discriminated from TDs. Precise conditions for TA introduction (range of

in coal mines in such countries as China and Russia,most of the coal mine methane(CMM) generated during mining is emitted to the atmosphere without any effective usage,because the methane concentration of CMM is relatively low and not allowed to be used as fuel for safety *** is one of the greenhouse ***,if it becomes possible to concentrate CMM to an acceptable level for use as fuel,this will greatly contribute to reduction of greenhouse gas *** the aim of gaining approval as a greenhouse gas emission reduction of the clean development mechanism(CDM) or joint implementation(Ji) project,we developed a CMM concentration system to apply the vacuum pressure swing adsorption(vPSA) technology using a high methane-selective adsorbent by Osaka Gas Co.,*** pilot-scale plant of a CMM concentration system was installed in a coal mine in Fuxin City in the northeastern China and a demonstration test was commenced in December *** the result,the pilot-scale plant successfully concentrated the raw material gas with a methane concentration of 21%and a flow rate of 1000 Nm3/h to 48%,which exceeded the target of the methane concentration performance(a 25%increase) .The methane recovery rate reached 93%.

Recharging of quantum confinement levels in SiGe quantum wells (QW) was studied by charge deep-level transient spectroscopy (Q-DLTS) for Si/SiGe/Si structures with different Ge contents in the SiGe layer. A peak with activation energy varying in the range from 0 to 100 mev in different tempera-ture intervals was observed in Q-DLTS spectra. Activation energies extracted from Q-DLTS measure-mens are in good agreement with energies of quantum confinement levels in the QW.

Calcium phosphate cements are of great interest for researchers and their applications in medical practice ***,they have a number of drawbacks including the insufficient level of mechanical properties and low degradation ***(MgNH4PO4)-based cements,which grew in popularity in recent years,despite their neutral pH and acceptable mechanical performance,release undesirable NH4+ions during their *** issue could be avoided by replacement of ammonia ions in the cement liquid with sodium,however,such cements have a pH values of 9–10,leading to ***,the main goal of this investigation is to optimize the composition of cements to achieve the combination of desirable properties:neutral pH,sufficient mechanical properties,and the absence of cytotoxicity,applying Na2HPO4-based cement *** this purpose,cement powders precursors in the CaO-MgO-P2O5 system were synthesized by one-pot process in a wide composition range,and their properties were *** optimal performance was observed for the cements with(Ca+Mg)/P ratio of 1.67,which are characterized by newberyite phase formation during setting reaction,pH values close to 7,sufficient compressive strength up to 22±3 MPa(for 20 mol.%of Mg),dense microstructure and adequate matrix properties of the *** set of features make those materials promising candidates for medical applications.

PPPM (Predictive, Preventive and Personalized Medicine) as a New Model of the National and international Healthcare Services and Thus a Promising Strategy to Prevent a Disease: From Basics to Practice

Nowadays the system of public health is constructed in such a manner so that its main objective is the recovery of an already sick person, while prediction and prevention receive little attention. Meanwhile the development of these aspects of medicine can lead to the ability to control morbidity among the population, to identify chronic and genetic diseases in the early stages of development, and thus to prevent their further progression. This will reduce traditionally high costs of sick people treatment and the number of disabled population, and improve the quality and duration of life. The elaboration of new fields of science that are working on the study and interpretation of data obtained during laboratory and clinical research, creation of new methods for diagnosis, prognosis and treatment, provides an opportunity now to implement a new strategy, called PPPM, and gets promising results, which should lead to further development of an existing medicine.
