Educational Migration into Secondary Vocational Institutions in the Context of Society's Well-being

In this article education and educational migration into secondary vocational institutions is considered as one of the most important factors of improving the well-being of the society. Actualization of such concepts as “knowledge economics” and “smart educations” and also the emergence of new tendencies on the world educational services market (internalization of education, commercialization of education; geographical changes in educational migration) contribute to it. In the context of such changes Russian education is capable of improving its competitiveness at the expense of reconsideration of the concept of vocational education. This article presents opportunities in stimulating educational migration into Russian secondary vocational institutions under current demographic situation and deficiency of qualified workers, and also specifies some system limitations and difficulties, which can be faced when realizing the strategy of educational services export. Some of them: bad potential students’ knowledge of Russian language, poor material and technical base, old-fashioned educational facilities and persisting differences in educational systems with the other leading countries of the world, inadequate legislation, etc. Listed in the article problems call for a better managed migration policy by using modern organizational and economic solutions, providing incentives and opportunities for the population influx

Optimization of adsorptive removal of α-toluic acid by CaO2 nanoparticles using response surface methodology

The present work addresses the optimization of process parameters for adsorptive removal of α-toluic acid by calcium peroxide (CaO2) nanoparticles using response surface methodology (RSM). CaO2 nanoparticles were synthesized by chemical precipitation method and confirmed by Transmission electron microscopy (TEM) and high-resolution TEM (HRTEM) analysis which shows the CaO2 nanoparticles size range of 5–15 nm. A series of batch adsorption experiments were performed using CaO2 nanoparticles to remove α-toluic acid from the aqueous solution. Further, an experimental based central composite design (CCD) was developed to study the interactive effect of CaO2 adsorbent dosage, initial concentration of α-toluic acid, and contact time on α-toluic acid removal efficiency (response) and optimization of the process. Analysis of variance (ANOVA) was performed to determine the significance of the individual and the interactive effects of variables on the response. The model predicted response showed a good agreement with the experimental response, and the coefficient of determination, (R2) was 0.92. Among the variables, the interactive effect of adsorbent dosage and the initial α-toluic acid concentration was found to have more influence on the response than the contact time. Numerical optimization of process by RSM showed the optimal adsorbent dosage, initial concentration of α-toluic acid, and contact time as 0.03 g, 7.06 g/L, and 34 min respectively. The predicted removal efficiency was 99.50%. The experiments performed under these conditions showed α-toluic acid removal efficiency up to 98.05%, which confirmed the adequacy of the model prediction
