IMPROVEMENT OF THE TECHNO¬LOGY FOR OBTAINING MANGANESE(IV) OXIDE FROM SECONDARY RAW MATERIALS
Authors: Yelatontsev D. , Kharitonova O. 
Published: April 2021

Today's level of integrated use of minerals and beneficiation wastes in Ukraine, in particular, at the Kryvbas GOK, is unsatisfactory, as it is generally allowing the production of additional types of construction products. The volume of mining is growing, but only a small percentage of the extracted volume is transferred to the finished product. The residue in the form of waste is returned to the environment, polluting it. The reason for this is the lack of technology for integrated mineral processing and waste disposal.
The article presents the results of industrial tests of off-balance manganese ore processing technology of Ordzhonikidze GOK with a manganese content of 15–30%. It is shown that nitric acid leaching of manganese with subsequent precipitation of impurities with soda or alkali allows you to consistently purify manganese from transition and alkaline earth metals. The obtained manganese oxide has a high degree of purity, which allows obtaining pure compounds Mn (NO3)2∙6H2O, MnO2 and metallic manganese for chemical current sources. The use of columnar clarifiers with a fluidized bed with the application of pulsations allowed to eliminate time-consuming filtration processes. Concomitantly formed sodium nitrate serves as a raw material for mineral fertilizers. Experimental studies on the beneficiation of off-balance manganese ores allowed us to determine the main technological parameters of the extraction of components and to develop a technological scheme of beneficiation.
According to the proposed technological scheme, it is possible to obtain high-quality concentrates of manganese (IV) oxide. The use of optimal technological parameters of enrichment allows up to 95% of Mn to be extracted from off-balance manganese raw materials. In the long run, this will reduce dependence on imports of manganese raw materials and significantly reduce the cost of domestic manganese products.

BIOSAFETY ASSESSMENT OF FLOUR AND YEASTS FOR BAKERY NEEDS ACCORDING TO MICROBIOLOGICAL INDICATORS
Authors: Коrnienko I. 
Published: April 2021

The problem of non-compliance with microbiological safety indicators of finished bakery products and flour of different types is formulated. It is noted that the reason for the development of bread disease, which is caused by pathogenic and opportunistic microorganisms, is poor quality flour. The solution of the problem is offered by use of symbiosis of lactic acid bacteria as a part of leaven which possess antagonistic properties in relation to many activators.
According to the results of microbiological research, pathogens of bread disease in wheat, spelled, oat and rye types of flour have been identified.The pathogenic micro­organisms present in the flour lead to accelerated spoilage of bread, reducing its nutritional value and safety in terms of microbiological parameters.
It is proposed to test the effectiveness of the use of biotechnological principles, which are based on the antagonistic properties of lactic acid bacteria. To determine the biosafety of the obtained yeast, microbiological studies were performed by seeding yeast samples on elective nutrient media Saburo, Blikfeldt, GMF agar, bifido- and lactoagar.
An improved leaven formulation for baking needs with an increased titer of lactic acid bacteria, which have powerful antagonistic powers, has been developed. Experiments have shown the effectiveness of the use of symbiosis of pure cultures of lactic acid bacteria in the composition of leavens to suppress diseases of bread, namely pathogens – Aspergillus niger, Mycormucedoand Bacillus subtilis.
The use of unleavened leavens with a high content of pure cultures of lactic acid bacteria in the practice of baking unleavened bread based on gluten-free types of flour contributes to the expansion of the range of functional bakery products.
GENERAL METHODS OF OPTIMIZA¬TION OF KINEMATIC AND DYNAMIC PARAMETERS OF THE MACHINE UNIT
Authors: Romaniuk O. , Telipko L. 
Published: April 2021

In steady-state operation, the kinematic and dynamic characteristics of the machine unit are periodic functions, as there is a periodic change in the forces and the transfer function of the drive mechanism. Accordingly, the task of finding methods to optimize the characteristics of the machine unit is mainly to reduce the amplitude of oscillations of the speed of the link by increasing the total moment of inertia by installing a flywheel on the shaft of the link, which increases the weight of the mechanism and its inertia.
To eliminate the corresponding shortcomings of additional flywheels, it is necessary in the process of preliminary design of the drive of the executive body of the machine unit to select such a standard gearbox, the swing torque of which would correspond to the additional flywheel, which is difficult to implement. It is more expedient to design new transmission mechanisms, the moments of inertia of rotating masses which could perform the function of a flywheel. The corresponding design principle makes it possible to solve the problem in the first approximation, but sometimes with great difficulty, so it is necessary to pay attention to the machine unit as a whole, and not just the mechanical transmission.
Based on the basic mathematical model of the machine unit using the principle of mass and force reduction, three variants of dynamic models were obtained depending on the choice of the link of construction, in order to optimize the kinematic and force parameters of the machine unit.
As a result of the analysis of dynamic models it is concluded that the most optimal solution of problems of optimization of kinematic and dynamic parameters of the machine unit is the complex approach which consists in designing not the drive scheme and the machine unit as a whole. That is, using only a standard electric motor, and the executive body of the machine and the mechanical transmission to design as a whole. This approach will provide the optimal solution to almost any problem posed to engineers and designers by modern production.
Kurt Daluege : un puissant véhicule de l’idéologie génocidaire de la SS
Authors: Mineau Par André 
Published: April 2021

Dans le cadre de ses fonctions, Kurt Daluege a été un opérateur génocidaire de haut niveau. Au service de l’indicible inhumanité de l’État nazi, il a présidé en partie aux crimes contre l’humanité commis en Pologne, en Bohême-Moravie et en Union soviétique. Mais il a été par ailleurs un véhicule important de la pensée SS. En plus de compter deux monographies à son nom, Daluege a rédigé ou prononcé un grand nombre d’articles et de discours, avec l’aide du personnel de son bureau. D’un point de vue quantitatif, sa production de textes, comparable à celle de Himmler, a été largement supérieure à celle de n’importe quel autre officier SS. La présente étude a pour objet précis l’idéologie SS telle que comprise et développée par Daluege. Il ne s’agira pas ici de décrire la police d’ordre pour elle-même, par rapport à son organisation et à son évolution. En laissant de côté les fonctions de gestionnaire de Daluege, il s’agira plutôt de présenter ce dernier en tant qu’orateur et en tant qu’auteur de la SS. On essayera ainsi de voir comment Daluege, dès les débuts du régime nazi, a contribué à sa manière à l’expression de la pensée SS, en choisissant d’aborder certains thèmes centraux d’une idéologie dont Himmler représentait, à l’intérieur de l’Ordre Noir, la caution finale. On doit remarquer ici que la pensée de Daluege comportait des éléments singuliers qui lui donnaient une coloration personnelle et particulière, à l’intérieur même de la pensée SS.
Sparingly developed tourist places on Lake Baikal
Authors: Nikolaeva A. S. , Kolodin K. I. 
Published: April 2021

The paper presents a sparing approach to the tourist and recreation development on Lake Baikal. This is conditioned by several factors: lack of sufficient theoretical basis on the regional architecture, the participation of the government, federal programs and projects on the development of tourism as an important socioeconomic sphere; high pollution and the constantly deteriorating ecosystem of the lake.The aim of this work is to develop a concept (model) of sparingly developed tourist and recreation places on Lake Baikal, a choice of types and principles of placing objects and their main architectural and functional properties. The paper presents the analysis and synthesis of the data from the Federal Target Programs, literature, methodologies, regulatory and design materials on the problem.As a result, the proposed model of sparingly developed tourist and recreation places includes intensive, normal, moderate and promising development. The main principles for the object placement are based on the mobility of stationary objects from the coastline, creation of research centers responsible for constant ecosystem monitoring, and traditional and fishing centers. These solutions allow creating the functioning system of the tourist cluster, interesting tourist routes and their architectural and functional diversity.
IFRS 9 Transition Effect on Financial Stability of Kosovo Commercial Banks
Authors: ÇOLLAKU Besmir , AHMETI Skender , ALIU Muhamet 
Published: April 2021

From January 1, 2018, most of the commercial banks in Kosovo adopted IFRS 9. The new standard introduces the expected credit loss model to allow for timely recognition of credit losses, estimated not only on the actual credit loss but also on forward-looking information regarding the current loan portfolio. Although, transition phases may lead to increasing impairments and a decrease in banks’ equity, which directly influences the financial stability of banks. This paper examines the day-one transition effect of IFRS 9 on the level of assets balance, allowance for loan losses, and capital regulatory class II of banks in Kosovo. To test our hypothesis, we have performed a comparative analysis for the six biggest commercial banks in Kosovo to identify correlation and causality between studied variables. As a statistical technique, we have employed a “paired sample t-test” where we compare financial indicators before and after adopting IFRS 9 to examine the impact on financial stability for commercial banks in Kosovo.
Our results are in line with the results of recent studies in the IFRS 9 field and conclude that the transition phase has a significant influence on the recognition of additional loan impairment but assets and capital regulations are not affected significantly. Results demonstrate the transition to IFRS 9 causes instability and re-consolidation of capital, but in the long-run reduce the possibility for large and sudden losses. Commercial banks in Kosovo should follow a balanced growth approach without compromising the quality of the loan portfolio.

Authors: Domingo Precious C 
Published: April 2021

Abstract. Pronunciation is essential in language learning; thus, English learners as a second language should strive for articulateness in sound patterns in English. This study aimed to determine the commonly mispronounced consonant sound of the Bachelor of Elementary Education students of the Visayas State University according to the manner and place of articulation. The instrument used in the study is the Golden-Fristoe Test of Articulation, which is composed of 44 words containing the different consonant sounds in English. The study results revealed that most consonant sounds misarticulated by the respondents were fricatives /z/, the nasal consonant sound /m/, the fricative sound /ð/, the affricate /dz/. With respect to the place of articulation, most consonant sounds misarticulated by the respondents concerning the place of articulation were alveolar /z/, the velar consonant sound /m/, the interdental sound /ð/, the post-alveolar /dz/. With these results, it is expected for the Filipino English language teachers to focus on teaching the alveolar and labiodental fricatives in teaching the consonant sounds because most students failed to articulate these sounds correctly.Keywords: English language, consonant sounds, pronunciationAbstrak.

Authors: Tamara Ajeng Pancar , Rifqi Muhammad 
Published: April 2021

This paper discusses Amir’s anxiety and motive in Khaled Hosseini’s “The Kite Runner". The library research method was applied in this research. In analyzing the data, the structural approach was used to scrutinize the intrinsic elements such as character, conflict, setting, and plot, while the psychological approach was used to examine extrinsic elements such as anxiety and motive of Amir as the main character in “The Kite Runner”. The results show that Amir, as the main character, is a caring, inferior, coward, optimistic, anxious, selfish, careless, sly, and patient person. It also indicates that Amir is a round static character since he has complex traits but his character as a caring person remains the same from the beginning to the end of the story. Besides, as the main character, Amir experienced both internal and external conflicts. The settings of time, social, and place showed the period in Afghanistan between 1975 and 2001 and the social stratum, Pashtun and Hazara in Kabul. Dealing with the plot, it starts from Amir’s effort to get Baba’s recognition and respect, Amir’s anxiety after betraying Hassan, Amir efforts to take Sohrab out from Kabul, the liberation of Sohrab from Assef, the Sohrab suicide trial, up to Amir’s effort to get back Sohrab trust. Also, Amir’s anxiety deals with realistic, neurotic, and moral anxiety, while the motives are safety and security need, belongingness and love need, and self-esteem needs.

Authors: Alrashdi Murad , Hameed Ahmed , Aljabr Abdullah 
Published: April 2021

Introduction: COVID-19 has harmed the economic, academic, and clinical pursuits of dental educational institutions and dental students. As dental associations, health agencies, and regulatory bodies around the globe announced the need for social distancing and stricter safety measures, some dental schools worldwide have been adapting to accommodate for such changes.Methods: This review attempts to provide a general picture of the early responses of some dental schools worldwide to the COVID-19 crisis and identify some of the regulations that influenced dental schools' initial decisions. An analytical approach was used to assess changes to dental school curriculums in didactic (academic/non-clinical) and clinical education, examinations, administration, and dental school research. The assessment was based on a web-based search of a variety of online global references including research articles, reviews, letters, press releases, and surveys regarding the early effect of covid-19 on dental education at some dental institutions in the U.S, Europe, and Asia from late February to early July of 2020. The review also offered further recommendations to dental school administrators regarding the future of dental education during the early stages of a pandemic.Conclusions: Innovations in technology and blended educational methodologies will continue to influence how certain dental schools around the world adapt to the changes caused by COVID-19 and better prepare dental education institutions for potential future public health disruptions.Clinical significance: Dental schools will need to adapt their education system to improve didactic, preclinical, clinical, administrative, and research components of dental education in response to the changes caused by COVID-19 and future pandemics.
