Published: December 2020

Background. Ukraine is one of the five largest producers and exporters of honey in the world.The problem of falsification of natural bee honey is urgent, which threatens the reputation of domestic products and can lead to a decrease in sales and may cause an export restrictions. The aim of the article is to analyze the current state, problems and prospects of development of the domestic market of bee honey. Materials and methods. Analysis, synthesis, statistical methods for assessing the dyna­mics and structure, scientific generalization and comparison of data from scientific sources. Results. The article analyzes the current state of the natural honey market in Ukraine, analyzes the dynamics of its production, quantity and structure of exports and imports. It is established that the production of natural honey in Ukraine has an unstable dynamics, while the quantity of exports of this product from Ukraine over the past 7 years has increased more than 5 times. Imports of honey to Ukraine are insignificant. The re­quirements to natural honey in Ukraine and the EU and the problems faced by domestic honey exporters are analyzed. It is established that the requirements for the quality of natural honey in the EU are high, these requirements have been implemented in Ukrai­nian legislation since 2019 and by 2023 will be mandatory for all market operators in Ukraine. The most common types of honey falsification in the domestic and world markets are described. It has been established that such methods of natural honey falsification as feeding bees with various preparations and syrups, forgery of parameters and characteristics of honey, admixture or complete replacement of natural honey with sugar syrups, etc. Conclusion. The Ukrainian honey market is one of the most promising and export-capable. However, it is characterized by a large number of problems that inhibit its development and require urgent solution. Further research in this area may be aimed at developing public policy measures to support the beekeeping industry and prevent honey counterfeiting.

Published: December 2020

Background. The most effective and cost-effective method of improving the supply of micronutrients is the enrichment of consumer foods, which are the most com­mon and consumed by all groups of adults and children. One of the means of iodine deficiency prevention is iodized salt usage. The aim of the work is to develop the recipe and substantiate the production techno­logy of cooked smoked sausages for functional purposes with the iodized table salt usage. Materials and methods. The object of research is boiled-smoked sausage cer­velat Vinnytskyi, which recipe includes iodized salt according to DSTU 4307: 2004 and water is replaced by ice. The boiled-smoked sausage of the highest grade – cervelat Ukrainskyi was takenas a control sample. The quality research of finished sausages was carried out in accordance with the requirements of DSTU 4591: 2006 on organoleptic parameters. The amount of iodine was determined by the Folgard argentometric method by back titration. Results. Methods of iodine enrichment of food products are analyzed. The mineral composition of meat as a raw material for the production of sausages is presented. Various formulations of mixtures for raw meat salting and formulations of control and test samples of sausages are given. In the recipe of cervelat Vinnytskyi, beef is used 1.7 times less, and pork on the contrary – 2.75 times more. However, neither soy granules nor starch, which is positive, are used in the formulation of the developed product. Also, the type of spicy food additive to enhance the accent of a particular flavor is changed. The technology of salting ground raw meat with iodized salt is proposed. The obtained data confirm that the majority of organoleptic parameters of the test sample does not differ from the control. According to the calculations, the sodium iodide content in boiled-smoked sausage, cervelat Vinnytskyi was determined at the level of 50 mcg per 100 g of product, while in the control sample it was absent. Conclusion. An experimental batch of boiled-smoked sausage cervelat Vinnytskyi of the highest grade with the use of iodized salt was made. The developed technology of cooked-smoked sausage salting with iodized salt allows to enrich the finished product with micronutrients and prevent iodine deficiency. The usage of iodized salt for a wide range of sausages requires further medical and biological research.

Simulation of a thin long rod that does not have critical forces and does not lose stability to Euler
Authors: Goroshko A. , Royzman V. , Petraschuk S. ,   Khmelnitskyi National University
Published: December 2020

The paper proposes a method of preventing the loss of Euler stability by thin rods. Such rods do not have critical forces and therefore do not lose stability from longitudinal compressive force. The method is based on a temporary change in the stiffness of the rod-support system, in particular, a change in the length of the rod between the supports when approaching the value of critical forces, and after passing the return to the previous value. The results of simulation modeling of the rod behavior are presented, which confirm the possibility to eliminate the loss of its stability with increasing compressive force to the maximum allowable value, which is determined from the condition of strength.
The determination of the information frequencies in the frame of the acoustic emission signals from the friction zone of tribosystems
Authors:   Kharkov National Technical University of Agriculture named after Petro Vasylenko, Fenenko K.
Published: December 2020

Based on the analysis of the works devoted to the selection of informative AE parameters for the diagnosis of tribosystems, in a theoretical way the information frequency ranges in the AE signal frame, where the maximum amplitudes values are observed, have been established. It has been theoretically and experimentally established that the information frequencies depend on the following groups of factors: the constructive; technological and operational ones. The degree of influence of the factors on the change in the frequency range is established. The operational factors (slip speed and load) change the frequency range from 106 to 584 kHz, the technological factors (roughness of the friction surfaces) change the frequency range from 118 to 618 kHz, the constructive factors (the size of the friction area of the stationary triboelement) change the frequency range from 140 to 530 kHz. It has been concluded that for the effective diagnosis of tribosystems, it is necessary to previously determine the information frequency range taking into account the factors listed above. The obtained results were confirmed experimentally with the calculation of the Fisher and Cochrane criteria, which allows one to state about the presence of a correlation between the theoretical values of the information frequencies generated by the tribosystem and the experimental values of the frequencies, where the maximum amplitudes were recorded, the correlation coefficient r = 0,88. The present analysis can be the basis for the development of a diagnostic method for tribosystems during their operation, which will increase the robustness and information content of the AE method.

A new method in determination of electrical parameters and geometrical structure of a power transformer applicable to failure diagnosis
Authors: Trần Ngọc Thạch , Nguyễn Thanh Phương , Nguyễn Trọng Huy , Phạm Đình Anh Khôi
Published: December 2020

In transmission and distribution networks throughout the world and in Vietnam nowadays, power transformers that are operating in the networks often are in black-box condition, i.e. there is no internal information available in terms of geometrical structure and material parameters. Geometrical structure of power transformers includes mainly winding structure and additional parts such as a static end ring or a would-in shield coil, if any whereas main materials in power transformers consists of conductive, insulating and magnetic materials… This makes difficulties in faults diagnosis that is based on the approach of physical modeling in general and the so-called electrical equivalentcircuit based modeling in particular since the physical approach requires internal information of power transformers for calculating electrical parameters. In case the electrical equivalent-circuit approach is used, the diagnosis is then conducted based on the change of values of electrical parameters in the circuit before and after an alarm or a suspicious fault that happens when power transformers are in operation. Relevant international investigations conducted recently have mainly focused on test objects as power transformers in grey- or white-box condition, i.e. during manufacturing phase, since they have available geometrical structure and material properties. To show a possibility that blackbox power transformers could be investigated in a physical manner, this article introduces a new method in determining electrical parameters and geometrical structure applied on a black-box power transformer. The research is based on the Frequency Response Analysis technique and has developed recent relevant investigations of the authors. This enables investigations of the value change of electrical equivalent parameters of this transformer on its simulated frequency responses for the purpose of physical fault diagnosis of power transformers later on.
Optimality conditions for set-valued optimization problems via scalarization function
Authors: Ha Manh Linh , Nguyen Dinh Huy , Nguyen Thi Thanh Truc
Published: December 2020

One of the most important and popular topics in optimization problems is to find its optimal solutions, especially Pareto optimal points, a well-known solution introduced in multi-objective optimization. This topic is one of the oldest challenges in many issues related to science, engineering and other fields. Many important practical-problems in science and engineering can be expressed in terms of multi-objective/ set-valued optimization problems in order to achieve the proper results/ properties. To find the Pareto solutions, a corresponding scalarization problem has been established and studied. The relationships between the primal problem and its scalarization one should be investigated for finding optimal solutions. It can be shown that, under some suitable conditions, the solutions of the corresponding scalarization problem have uniform spread and have a close relationship to Pareto optimal solutions for the primal one. Scalarization has played an essential role in studying not only numerical methods but also duality theory. It can be usefully applied to get relationships/ important results between other fields, for example optimization, convex analysis and functional analysis. In scalarization, we ussually use a kind of scalarized-functions. One of the first and the most popular scalarized-functions used in scalarization method is the Gerstewitz function. In the paper, we mention some problems in set-valued optimization. Then, we propose an application of the Gerstewitz function to these problems. In detail, we establish some optimality conditions for Pareto/ weak solutions of unconstrained/ constrained set-valued optimization problems by using the Gerstewitz function. The study includes the consideration of problems in theoretical approach. Some examples are given to illustrate the obtained results.

Published: December 2020

O artigo aborda as complexidades, em interação, da produção cultural negra e das bordas, compreendendo as tramas presentes na produção da Trupe Liuds através da pesquisa bibliográfica e entrevista com a diretora do grupo. Este teatro circense é composto por palhaços negros, da periferia do Perus na cidade de São Paulo, que objetivam levar cultura e arte para crianças e jovens. O objeto, enquanto produção cultural negra e das bordas, também é contextualizado na cultura popular mestiça em constante ebulição no Brasil, já que, desde a diáspora, os povos da África conversam e conflagram com todos os conjuntos móveis assimétricos correntes no país: subúrbios, classes baixas e médias, índios quase-urbanos, urbanos quase-índios, migrantes e imigrantes de toda parte etc. Além da atenção à riqueza de tal condição, também perpassamos pelos impactos sociais das criações da Trupe Liuds, uma vez que também tratam de problemáticas sociais, raciais, de gênero etc. e que podem facilitar para o rompimento do pensamento autoritário. Todavia, observamos as saídas possíveis da lógica binária dominante; a produção cultural da qual tratamos compõem seu embate pela alegria, pelas alianças, pela graça, pelo riso, pela cor, pela sonoridade e pelo fluxo dos diversos corpos que são colocados em diálogo com a paisagem cultural, nas suas relações entre natureza e cultura. Assim, enfrentam-se aqui os temas sociais a partir da capacidade dos desvios criativos e das derivações de uma produção cultural lúdica, rítmica e alegre.

Hepatitis B Virus: From Diagnosis to Treatment
Authors: GUVENIR MERYEM , ARIKAN AYSE
Published: December 2020

Hepatitis B infection is still a global concern progressing as acute-chronic hepatitis, severe liver failure, and death. The infection is most widely transmitted from the infected mother to a child, with infected blood and body fluids. Pregnant women, adolescents, and all adults at high risk of chronic infection are recommended to be screened for hepatitis B infection. The initial analysis includes serological tests that allow differentiation of acute and chronic hepatitis. Molecular assays performed provide detection and quantification of viral DNA, genotyping, drug resistance, and precore/core mutation analysis to confirm infection and monitor disease progression in chronic hepatitis B patients. All patients with chronic hepatitis B should be treated with antiviral medications and regularly monitored for efficient treatment. The current treatment is based on nucleos(t)ide analogs and pegylated interferons that save lives by decreasing liver cancer death, liver transplant, slow or reverse the progression of liver disease as well as the virus infectivity.

With the significant increases in the human population, global aquaculture has undergone a great increase during the last decade. The management of optimum conditions for fish production, which are entirely based on the physicochemical and biological qualities of water, plays a vital role in the prompt aquaculture growth. Therefore, focusing on research that highlights the understanding of water quality and breeding systems’ stability is very important. The biofloc technology (BFT) is a system that maximizes aquaculture productivity by using microbial biotechnology to increase the efficacy and utilization of fish feeds, where toxic materials such as nitrogen components are treated and converted to a useful product, like a protein for using as supplementary feeds to the fish and crustaceans. Thus, biofloc is an excellent technology used to develop the aquaculture system under limited or zero water exchange with high fish stocking density, strong aeration, and biota. This review is highlighted on biofloc composition and mechanism of system work, especially the optimization of water quality and treatment of ammonium wastes. In addition, the advantages and disadvantages of the BFT system have been explained. Finally, the importance of contemporary research on biofloc systems as a figure of microbial biotechnology has been emphasized with arguments for developing this system for better production of aquaculture with limited natural resources of water.

Currently, intensive research is underway to develop remotely controlled and autonomous underwater robots that use technical vision systems. Typical examples of tasks that can be solved using them are: monitoring the environment; detecting objects and obstacles; approaching the robot with an object; performing operations with objects. The article focuses on the problems of constructing images of the working space of an underwater robot designed to perform operations with objects based on information received from a stereo camera. Robust algorithms for constructing 3D images of the robot's workspace based on a perspective camera model and using triangulation and clustering methods are proposed and tested on real data. Image processing algorithms take into account the presence of a waterproof shell.
