Synthesis and Spectroscopic Characterizations of Ni(II) Thiosemicarbazone Bearing Anthracene

The X-ray structure of 9-anthraldehyde-4-methyl-3-thiosemicarbazone was firstly determined. The Ni(II) complex with this ligand was prepared upon reaction with chloride salt. Mass spectrometry result confirms correct formulation of the complex. Unusual 1H NMR signal pattern of anthracene moiety reveal cis arrangement cemented by intramolecular p–p stackings between aromatic rings. As a result of this interaction, the electronic structure of anthracene ring is perturbed and gives rise to structureless and broad absorption and emission bands.

Implementation of the fsbu requirements 5/2019 “Reserves” in organization of accounting of reserves

The results of the activity of an economic entity, in many respects by the rationality of the management of circulating assets, including their group as reserves. Each entity implements its own process control mechanism, ideally should ensure the stability and regularity of production processes, as well as efficiency with the highest efficiency. Therefore, the correct formulation of accounting inventory within the framework is essential. Today, the organization of accounting is under the special attention of employees of accounting services, since from January 1, 2021, the requirements of the Federal Accounting Standard 5/2019 “Inventories” are mandatory for application in practice. In this regard, the accounting services of the subjects need to take appropriate practical steps in order to successfully fulfill the economic requirements of the standard starting from the reporting for 2021. The article discusses measures for organizing accounting of stocks and the possibility of their implementation in the practice of economic entities.

A proposed guide in the light of Marzano's model of learning dimensions for teaching the unity of the Arab and Islamic world to middle second graders in The Kingdom of Saudi Arabia: دليل مقترح لتعليم وحدة العالم العربي والإسلامي لطالبات الصف الثاني المتوسط بالمملكة العربية السعودية في ضوء نموذج مارزانو لأبعاد التعلم

The purpose of the research was to provide a proposed guide for teaching social studies in light of Marzano’s Dimensions of Learning Model. To achieve this goal, a guide was prepared to use the said Model for the Unit of the Arab and Islamic worlds of the social studies course and citizenship pertaining to the second intermediate grade in the Kingdom of Saudi Arabia for the second semester of the year 1440/1441H. The guide was presented to (6) arbitrators specializing in the field of curricula and instruction methods to ensure the correct formulation of goals, and the appropriateness of educational activities with the steps of Marzano’s Dimensions of Learning Model. Based on their opinions, some educational activities were modified, and some language errors were corrected. The arbitrators’ approval of the guide amounted to 98%, and thus the guide was finalized. The researchers recommended training of female teachers on using the Marzano’s Dimensions of Learning Model when teaching social studies, and directing them to utilize the proposed guide to Marzano’s Dimensions of Learning Model when teaching geography.

A note on the paper "Optimality conditions for nonsmooth interval-valued and multiobjective semi-infinite programming"

A nonsmooth semi-infinite interval-valued vector programming problem is solved in the paper by Jennane et all. (RAIRO-Oper. Res. doi: 10.1051/ro/2020066, 2020). The necessary optimality condition obtained by the authors, as well as its proof, is false. Some counterexamples are given to refute some results on which the main result (Theorem 4.5) is based. For the convinience of the reader, we correct the faulty in those results, propose a correct formulation of Theorem 4.5 and give also a short proof.

FEATURES OF STATEMENT OF A QUESTIONS FOR THE FORMATION OF SKILLS OF CRITICAL THINKING OF LEARNERS

Digitalization of modern society leads to the need for the formation and development of critical thinking of learners. The purpose of the article is to study the problem of the development of critical thinking of schoolchildren by posing educational questions. In the course of the study, following results were obtained: the scope and basic principles of compiling questions for the development of critical thinking of schoolchildren were identified, the conditions for the formation of mental skills were identified. Conclusions are drawn: the correct formulation of questions in teaching mathematics contributes to the development of mathematical and analytical competencies of students. Pupils' understanding of issues goes through 4 main stages: setting goals, finding information, drawing up an action plan, choosing a solution strategy.

FEATURES OF CONSTRUCTION OF GEOSTATIC MODELS OF DEPOSITS IN AKSHABULAK SEDIMENTS OF ARYSKUM TROUGH

The features of constructing a geostatic model (GSM) of the Akshabulak productive horizon in the composition of oil-saturated reservoirs Yu-0-0, Yu-0-1, Yu-0-2 and Yu-0-3 are considered. Modern approaches to the integration of the accumulated geological and geophysical data into the GSM require the necessary work, primarily such as sedimentological examination of the core and its integration with the results of logging and seismic data. The correct formulation of the problem, its support by the customer at all stages, due to which a close connection between the performed studies and production requests was ensured, were the key to obtaining a high-quality result when solving a seemingly ordinary modeling problem

A root-and-pattern approach to word-formation in Chinese

This paper argues that compounding, the major source of word-formation in Chinese, and the root-and-pattern system in Hebrew involve fundamentally the same syntactic operations and observe the same locality constraints, despite the salient differences. More specifically, it addresses the well-known continuum that the coordinate and attributive compounds behave more like words, whereas resultative and subordinate compounds are much more like phrases. It puts forward the idea that this continuum can be accounted for by assuming that there is a distinction between word-formation from roots and word-formation from words, with the former giving rise to more lexical properties and the latter more phrasal properties. The paper also discusses some related issues, such as the correct formulation of word-level phases and the structure of the major types of compound words in Chinese.

On minimal surfaces on two-step Carnot groups

For graph mappings constructed from contact mappings of arbitrary two-step Carnot groups, conditions for the correct formulation of minimal surfaces’ problem are found. A suitable notion of the (sub-Riemannian) area functional increment is introduced, differentiability of this functional is proved, and necessary minimality conditions are deduced. They are also expressed in terms of sub-Riemaninan mean curvature.

The Solution Equivalence to General Models for the RIM Quantifier Problem

Hong investigated the relationship between the minimax disparity minimum variance regular increasing monotone (RIM) quantifier problems. He also proved the equivalence of their solutions to minimum variance and minimax disparity RIM quantifier problems. Hong investigated the relationship between the minimax ratio and maximum entropy RIM quantifier problems and proved the equivalence of their solutions to the maximum entropy and minimax ratio RIM quantifier problems. Liu proposed a general RIM quantifier determination model and proved it analytically by using the optimal control technique. He also gave the equivalence of solutions to the minimax problem for the RIM quantifier. Recently, Hong proposed a modified model for the general minimax RIM quantifier problem and provided correct formulation of the result of Liu. Thus, we examine the general minimum model for the RIM quantifier problem when the generating functions are Lebesgue integrable under the more general assumption of the RIM quantifier operator. We also provide a solution equivalent relationship between the general maximum model and the general minimax model for RIM quantifier problems, which is the corrected and generalized version of the equivalence of solutions to the general maximum model and the general minimax model for RIM quantifier problems of Liu’s result.
