This paper systematizes the empirical results on efficiency concepts applied to higher education institutions, data envelopment analysis (DEA) adjusted to heterogeneous samples, inputs and outputs chosen for these institutions and factors tended to make universities efficient. Special attention is paid to the consistency of results yielded by different models. 相似文献

The synthesis of organosilicon derivative monomers and polymers characterized with sorption properties has been performed. The synthesized organosilicon polymers have been investigated as sorbents for heavy (Hg(II)) and noble (Ag(I), Au(III), Rh(II), Pd(II), and Pt(IV)) metals. The coefficients of the interphase metal distribution have been estimated. 相似文献

The 1500-1700 cm-1 frequency region in the spectrum of PAN copolymer fibre is structurally sensitive and can be used for the relative characterization of intra- and intermolecular interactions and level of supermolecular structural organization in fibres fabricated in different conditions, in particular, as a function of the nature of the solvent. In the systematic investigation of PAN copolymer fibres, the selectivity of absorption in the indicated frequency region could be analytically useful for further studies to solve both scientific and applied problems. 相似文献

For the first time, complex oxide NaFeYO7 + x was prepared by SHS (T c = 750–1200 K, U = 1–4 mm/s) in the Na-Fe-Y-O system. Explored was the influence of reagents ratio on combustion limits for the mixtures under study. Combustion products were characterized by XRD, SEM, EDX, chemical analysis, and magnetic measurements. Single-phase NaFeYO7 + x was obtained at an excess of sodium in green mixtures. To stabilize the product, the water-washing procedure was used just after synthesis. The synthesized material has a cubic crystal structure with a cell parameter close to that of sodium yttrate NaYO2, it exhibited very weak magnetic properties, and overly-stoichiometric oxygen content. The product is heat resistant up to 450 K. The synthesized product is a new inorganic superoxide with good technological perspectives for use as a solid oxygen-containing material. 相似文献
