Flipped classroom model

Flipped classroom is an active, student-centered approach that was formed to increase the quality of period within class. Generally, this approach whose applications are done mostly in Physical Sciences, also attracts the attention of educators and researchers in different disciplines recently. Flipped classroom learning which wide-spreads rapidly in the world, is not well recognized in our country. That is why the aim of study is to attract attention to its potential in education field and provide to make it recognize more by educators and researchers. With this aim, in the study what flipped classroom approach is, flipped classroom technology models, its advantages and limitations were explained

Flipped learning as interactive learning environment

The use of the flipped classroom as an alternative to the traditional learning environments has been increasingly attracting the attention of researchers and educators. The advancement in technological tools such as interactive videos, interactive in-class activities, and video conference systems paves the way for the widespread use of flipped classrooms. It is even asserted that the flipped classroom, which is used to create effective teaching environments at schools, is the best model for using technology in education. Studies about the flipped classroom appear in different disciplines including information systems, engineering, sociology, and humanities, mathematics education, and English composition. The purpose of this paper is to fulfil the needs regarding the review of recent literature on the use of the flipped classroom approach in education

On digital approximations for elliptic boundary value problems

We study certain discrete boundary value problems for discrete analogue of model elliptic pseudo-differential operator in discrete Sobolev-Slobodetskii spaces. Existence and uniqueness theorems are proved and a comparison between discrete and continuous solutions are give

Features of Nickel-Cadmium Batteries Recycling

The issue of operated-off alkaline nickel-cadmium batteries recycling is currently relevant due to a number of aspects: economic, environmental and social. It is most acute across the national corporation JSC Russian Railways. The article deals with some technological features of operated-off alkaline nickel-cadmium batteries recycling with valuable components being extracted (from the example of nickel-cadmium storage batteries of JSC ”RZD” rolling equipment). The results of leaching in Trilon B synthetic oxides solution, the presence of which is possible in the raw material being processed, are presented in the study. Based on the study of leaching processes of CdO, NiO, FeO, Femet and Fe2O3 in Trilon B solution, the dependence of complexing on the pH of the solution was revealed. The experimental site of the hydrometallurgical processing of the research center (OCGP IC) in the GMO KhMC PJSC ”Uralelectromed” was selected as the testing one for the technology proposed. As a raw material for the tests, a lot of negative lamellae packed in alkaline storage batteries of two different types were used. They were obtained as a result of preliminary drying and cutting at OOO Kursk factory ”Accumulator”. The particle size is 90% - 0.1 mm. The results obtained during the research allowed the author to formulate a hypothesis about the practical use of Trilon B for the processing of operated-off alkaline nickel-cadmium batteries with the extraction of valuable components having greater economic, environmental and social benefits compared to methods based on pyro metallurgy. Keywords: nickel-cadmium batteries, recycling, Trilon B, Russian Railways, hydrometallurgica

БУХГАЛТЕРСЬКИЙ ОБЛІК ФІНАНСОВИХ РЕЗУЛЬТАТІВ ЯК ПЕРЕДУМОВА ПОПЕРЕДЖЕННЯ БАНКРУТСТВА ПІДПРИЄМСТВА

This paper analyzes the analyzes of the dynamics of the financial results of enterprises, the influence of the factors leading to reduced solvency of domestic enterprises, the necessity of timeliness of financial information as a prerequisite to avoid bankruptcy.Amidst uncertain economic environment one gives much attentionto the bankruptcy issue because many domestic businesses are in crisis or bankruptcy. This is due to the financial failure of the company to overcome the economic crisis. The increasing number of bankrupt enterprises is influenced by most companies, which work with borrowed funds being insolvent and unable to fulfill their obligations not only to suppliers, but also to major creditors.В статье проанализированы аналитическую информацию о динамике финансового результата предприятий, определено влияние факторов, приводящих к снижению платежеспособности отечественных предприятий, обоснована необходимость своевременности предоставления бухгалтерской информации как предпосылки избежания банкротства предприятия.В статті проаналізовано аналітичну інформацію щодо динаміки фінансового результату підприємств, визначено вплив факторів, що призводять до зниження платоспроможності вітчизняних підприємств, обґрунтовано необхідність своєчасності надання бухгалтерської інформації як передумови уникнення банкрутства підприємства

On discrete boundary-value problems and their approximation properties

Discrete analogs of pseudo-differential operators and equations in discrete Sobolev-Slobodetsky spaces are considered. Using suitable discrete boundary conditions, we prove the unique solvability of the discrete boundary-value proble

Structural and transport characteristics of substituted bismuth niobates

The results of studying solid solutions with the composition of Bi 3Nb1 - y Zr y O7 ± δ, Bi2.95Y0.05Nb1 - y Zr y O 7 ± δ (y = 0-0.5; Δy = 0.1), and Bi 6.95Y0.05Nb2 - y Zr y O 15.5 (y = 0.1-1; Δy = 0.1) are presented. XRD and electron microscopy with X-ray microanalysis are used to determine the homogeneity regions of solid solutions; crystallochemical parameters are calculated. It is shown that irrespective of the ratio of Bi: Nb, two cubic phases are formed at an increase in the dopant amount. One of these represents a solid solution based on Bi3NbO7 (δ-phase) and the second one is a solid solution based on δ-Bi2O3 (δ′-phase). Conductivity of sintered samples is studied using the impedance spectroscopy technique. Introduction of yttrium into the bismuth sublattice results in no increase in conductivity of solid solutions, while in the case of the ratio of Bi: Nb = 3: 1, overall conductivity of solid solutions is somewhat higher at similar dopant concentrations. © 2013 Pleiades Publishing, Ltd

Frames of solutions and discrete analysis of pseudo-differential equations
