English is an analytical language, so in English, the word order is important for understanding sentences and phrases. Practicing construpcting noun phrases with the correct order of adjective requires constant practice with feedback. As teachers' time for verifying assignments is limited, we propose to use a tutoring system, which can generate step-by-step feedback. It will help students develop the skill of arranging adjectives in the correct order.

This article describes the developed tool for creating a report on the effectiveness of sales channels for the hierarchical structure of sales channels. The developed model for the report on sales channels takes into account the type of source, the criterion for the freeness of the sales channel, the source of traffic and the source of customers themselves. The ROI is estimated and customer conversion activity data is tracked. The article also describes the results of the implementation of the model and its use.

This paper describes the problems of identifying effective sales channels for services working with a call center. The solution is presented in the form of a multi-level model of sales channels that works with call tracking with a limited number of phone numbers. This approach can be applied in services of small and medium-sized businesses, which cannot afford a large number of phone numbers for call tracking.

The estimation of the dependence of anode potential of the temperature and current density. It is established that the activation energy of the anodic oxidation process HORTA, HORTA-I1 and OITA decreases with increasing potential, which corresponds to the limiting stage of charge transfer. The activation energy of the anodic process refers to the collective processes of transformation of the catalytic coating and anodic oxidation of the chloride ions. The latter process limits the adsorption of atomic chlorine, and the increase in activation energy is correlated with increased corrosion resistance. The dependence of the activation energy of from the content in the catalytic layer of iridium has an extreme character. The maximum is reached when the content of iridium 60-70%.

"Effective and affordable sorbents produced from natural organic raw materials and waste products of agricultural and livestock origin, because these sorbents are part of existing ecosystems and, therefore, best meet environmental requirements, in order to ensure the rational nature management and preservation of consumer properties of water resources. For the solution of actual problems, such as the removal of oil and oil products from water surface, as sorbents was investigated by the waste processing of leather and agricultural industries: wool (sheep and goat) and feather (chicken and waterfowl). It is established that application of organic and mineral acids at certain concentrations , for treatment of wastes from the processing of wool allows to obtain sorbents directional spectrum for removal of oil products (such as diesel gas oil and engine oil) and oil from water. The modifiers of wool and feathers obtained after the chemical treatment, was used to study the sorption of oil and oil products from water surface. It was determined by sorption characteristics of the modified sorbents, such as oil capacity and moisture absorption. The kinetics of sorption–desorption of oil, which showed that the greatest degree of absorption is observed for the first 10-15 minutes. It is found that wastes from goat and sheep wool have a 90% holding capacity that persists in time. It was revealed the effect of temperature on oil absorption capacity of the sorbent and the calculation of heat of adsorption. The temperature increase leads to a reduction of the capacity of emulsified oil, reducing the degree of purification by 15-30%."

The effect of sodium chloride concentration on the job ORTA electrodes. It is found that the electrodes OPTA, especially in the sodium chloride concentration below 50 g/liter, three groups occur conjugate processes, oxidation of chloride ions, the solid-phase oxidation of the anode material, dissolution of the active catalytic coating. The processes of oxidation of chloride ions prevail in current densities of 0.001 - 0.032 A/cm2 at high current densities become essential processes of oxidation of the ruthenium oxide coating. The oxidation of chloride ions, especially at concentrations less than 50 g/liter can be described as occurring in a constantly evolving anode active material due to its corrosion and solid-phase oxidation.

In our work we researched the possibility of producing active chlorine out of fresh natural water through it's direct elecrolysis. We discovered how the anode's corrosion resistanse relates to the ruthenium oxide and iridium oxide ratio in the anode's coating. We also researched their properties: chlorine outcom dependance on current, cell voltage, and active chlorine concentration increase dynamics in processed water from Don river.
