Trade, economic and sanctions wars: an attempt to theoretically differentiate the ideas in the context the international relations science
Authors: Mukhamadeev Dmitriy Viktorovich , Shevchenko Yan Nikolaevich
Published: May 2020

The research purpose of this article is to attempt to differentiate the concepts and theoretical backgrounds of economic sanctions and trade wars as popular instruments of economic coercion. In the authors’ opinion, such differentiation is critically important for the conceptualization of economic sanctions as a foreign policy instrument kindling the interest of both specialists in international relations and the global and regional international politics practitioners. From a practical perspective, the interest in analyzing this issue is determined by the fact that over the past century, economic sanctions have become one of the key instruments of achieving a state’s foreign policy goals. They are mostly used by developed countries with extensive economic and technological capabilities (e.g. U.S.), which are striving for abatements of their less powerful partners regarding foreign and domestic policy issues. Yet another argument in favour of studying economic sanctions, trade wars and other instruments of economic coercion in the context of the theory of international relations is the possibility to shed more light on the nature of power as the most significant concept of modern political science. A detailed analysis of theoretical discussions about the phenomenon of trade and economic wars compared with economic sanctions allows the authors to outline a set of fundamental differences between these phenomena in the context of modern economic diplomacy.   
Russia’s Soft Power: specificity of understanding and evaluating
Authors: Borisov Aleksey Vladimirovich
Published: May 2020

The article contains the critical analysis of the understanding of “soft power” in Russia as a state’s foreign policy instrument. The author notes that the strategic planning guidelines defining the fundamental principles, priorities, goals and tasks in the field of foreign policy and national security contain numerous references to the importance of “soft power” and emphasize the necessity of increasing Russia’s role in the global humanitarian space. However, the instrumental understanding contradicts the initial understanding of “soft power” as a way to legitimize a state’s foreign policy efforts and leads to refocusing from the evaluation of the effect of using humanitarian technologies to the evaluation of the humanitarian activity itself. In the author’s opinion, such approach hampers the appropriate usage of Russia’s resources of “soft power” for the purposes of its foreign policy, and sidetracks from the understanding that the efforts aimed at the cultivation of soft power are directed towards a state’s internal policy, whereas being only projected outwardly.

The role of linguistics in the development of modern literary criticism
Authors: Maiga Imirana Seydou
Published: May 2020

The nineteenth century is the age of linguistics, which opened the horizons for human sciences in this age, especially the monetary field, which is considered the first beneficiary of the fruits of linguistics, where both work on one material: language.

However, linguistics was interested in the ordinary language, while the criticism in the creative language took criticism from the impressionist stage to rely on technical mechanisms to prevent the critic from falling into the trap of self-impression. And with the scientific breakthrough of criticism resulting from the exchange of criticism and linguistics we found several approaches from structural to deconstruction, stylistic, which wanted to contain the page rhetoric, and other approaches that continue to breed with the development of linguistics, and do not forget the analysis of speech, and the mechanisms of the reader and his response. These scientific observations, which will be discussed in this study in the following lines.
Controlled Diffusion of Photoswitchable Receptors by Binding Antielectrostatic Phosphate Oligomers
Authors: MacDonald Thomas , Feringa Ben L. , Price William S. , Wezenberg Sander J. , Beves Jonathon
Published: May 2020

Dihydrogen phosphate anions are found to spontaneously associate into anti-electrostatic oligomers via hydrogen bonding interactions at millimolar concentrations in DMSO. Diffusion NMR measurements supported formation of these oligomers, which can be bound by photoswitchable anion receptors to form large bridged assemblies of approximately three times the volume of the unbound receptor. Photoisomerization of the oligomer-bound receptor causes a decrease in diffusion coefficient of up to 16%, corresponding to a 70% increase in effective volume. This new approach to external control of diffusion opens prospects in controlling molecular transport.
Selecting Machine Learning Models for Metallic Nanoparticles
Authors: Barnard Amanda , Opletal George
Published: May 2020

The outcome of machine learning is influenced by the features used to describe the data, and various metrics are used to measure model performance. In this study we use five different feature sets to describe the same 4000 gold nanoparticles, and 14 different machine learning methods to compare a total of 70 high scoring models. We then use classification and regression to show which meta-features of data sets or machine learning algorithms are important when making a selection. We find that number of features, and those that are strongly correlated, determine the class of model that should be used, but overall quality is almost entirely determined by the cross-validation score, regardless of the sophistication of the algorithm.

Published: May 2020

The spreading COVID-19 pandemic has brought the world to a halt in 2020. One of the major challenges is the lack of effective antiviral drugs. Drug and vaccine development typically takes years; a practical approach to formulate knowledge-based prescriptions is to conduct in silico screening for drugs and compounds that has the potential to disrupt viral protein functions. By evaluating the dataset from the “Shennong project”, an in silico screening of the DrugBank library against SARS-CoV-2 proteins, we identified chlorogenic acid and rutin displayed a strong affinity with diverse viral proteins. Chlorogenic acid is naturally present in coffee in large quantity, and rutin is available as nutraceutical products, both compounds are considered safe to consume, hence could potentially aid the recovery or treatment for COVID-19 patients at low health risk. We emphasise that the results require further clinical clarification, the impact of this work shall be examined by professionals carefully.

Published: May 2020

Poly(alkylene 2,5-furanoate)s are considered as the most attractive and interesting alternatives to replace oil-based terephthalic polymers. These furan-based polyesters can be synthesized using fully bio-based synthetic strategies, allowing to reduce the environmental impact of plastics. At the same time, these polymers have shown outstanding thermal, mechanical and gas-barrier properties. All these results envisage their industrial use in the near future. Now, considering the downscaling of the products’ size towards the nanometer scale, we present a study of the morphology and nanomechanical properties of poly(alkylene 2,5-furanoate) thin films. Using Atomic Force Microscopy, we report the development of nanostructures upon crystallization, following different thermal treatments, for thin films with thicknesses below 200 nm. Moreover, we studied the impact of crystal growth in the nanomechanical properties of these materials. We found that the polymer thin films preserve their excellent mechanical response even in the confined geometry, as proved by the Young’s moduli values close to the GPa, accompanied by high surface stiffness, and low indentation depths. The poly(alkylene 2,5-furanoate) thin films were found to have nanomechanical properties comparable to those of the oil-based poly(ethylene terephthalate), a further evidence that in the future they could replace traditional polymers in several applications.
Autocatalysis in Chemical Networks: Unifications and Extensions
Authors: Blokhuis Alex , Lacoste David , Nghe Philippe
Published: May 2020

Autocatalysis is an essential property for theories of abiogenesis and chemical evolution. However, the different formalisms proposed so far seemingly address different forms of autocatalysis and it remains unclear whether all of them have been captured. Furthermore, the lack of unified framework thus far prevents a systematic study of autocatalysis. Here, we derive general stoichiometric conditions for catalysis and autocatalysis in chemical reaction networks from basic principles in chemistry. This allows for a classification of minimal autocatalytic motifs, which includes all known autocatalytic systems and motifs that had not been reported previously. We further examine conditions for kinetic viability of such networks, which depends on the autocatalytic motifs they contain. Finally, we show how this framework extends the range of conceivable autocatalytic systems, by applying our stoichiometric and kinetic analysis to autocatalysis emerging from coupled compartments. The unified approach to autocatalysis presented in this work lays a foundation towards the building of a systems-level theory of chemical evolution.

Authors: Verma Vikrant , Pathak Manish , Kumar Amit , Kumar Amit
Published: May 2020

The current research explains the development of a new method and its subsequent validation by a novel HPLC method in fluconazole tablets. Inertsil Octadecyl silica C18 column having dimensions of length 150 mm, diameter 4.6 mm, particle size 5 μm was exploited for the method development, and the mobile phase embodies buffer pH 4 and acetonitrile in the combo of 40:60. Wavelength exploited for the segregation was 289 nm. The volume of injection was preserved at 20 µl. The new developed method has been established to demonstrate linearity in the range of 10 to 30 µg /ml correspondingly. Average recovery established to be 101.571, 100.315, and 99.021, the standard deviation was established to be 0.93834, 0.986418, and 0.989741, and % R.S.D was established to be 0.92382, 0.98331, and 0.999526. The percentage recovery was established to be within prescribed restrictions. The limit of detection was established to be 0.0080. The limit of quantitation was established to be 0.0051. In assay studies, an average assay was found to be 95.966, and standard deviation and % RSD of the assay was found to be 0.6021  and  0.6274, respectively. The method was found to be specific as there was no intrusion from impurities and excipients. Extensive diversity of mobile phase combos was utilized for the research and flow rate preserved at 1.3 ml/min all through the process. After carefull and systemic investigation of various research articles and review articles, it is observed that H.P.L.C method development and validation of fluconazole has been done in various pharmaceutical dosage forms, but till now a smaller amount of work is executed on dosage forms of solid nature, and hence there is huge prospective for research to be done in this area for new methodology to be developed in pharmaceutical dosage form of solid nature by means of dissimilar mobile phase combos and different strategy adopted by use of chromatography software which avoids the problems and demerits associated with present methods

Authors: Nithin Diwagar K  , Sridevi M  , Chitra S
Published: May 2020

Galectin-3 is a beta-galactoside binding animal lectin, which is frequently associated with tumour progression and metastasis. In recent years, overexpression of Galectin-3 has been reported in various human cancers and more frequently in thyroid neoplasms. The aim of this study was to analyze the histomorphological characteristics of malignant thyroid neoplasms, subtype them according to the established classification system and to evaluate the expression of Galectin-3 immunostaining in papillary thyroid carcinoma. A total of 30 cases were included in the study, out of which 28 cases were papillary thyroid carcinoma and its variants and one case of medullary and anaplastic carcinoma. Majority of the papillary thyroid carcinoma cases were positive for Galectin 3 immunostaining (25/28 cases – 89%) in our study. We conclude that galectin-3 is consistently expressed in papillary carcinoma thyroid; however, there are few false-negative cases in this study and also other studies have reported Galectin 3 overexpression in non-papillary tumors. Hence, we cannot depend on Galectin 3 expression alone as a single diagnostic tool to detect papillary thyroid carcinoma.

Published: May 2020

During development, neurons adjust their energy balance to meet the high demands of robust axonal growth and branching. The mechanisms that regulate this tuning are largely unknown. Here, we show that sensory neurons lacking liver kinase B1 (Lkb1), a master regulator of energy homeostasis, exhibit impaired axonal growth and branching. Biochemical analysis of these neurons revealed reduction in axonal ATP levels, whereas transcriptome analysis uncovered down-regulation of Efhd1 (EF-hand domain family member D1), a mitochondrial Ca2+-binding protein. Genetic ablation of Efhd1 in mice resulted in reduced axonal morphogenesis as well as enhanced neuronal death. Strikingly, this ablation causes mitochondrial dysfunction and a decrease in axonal ATP levels. Moreover, Efhd1 KO sensory neurons display shortened mitochondria at the axonal growth cones, activation of the AMP-activated protein kinase (AMPK)–Ulk (Unc-51–like autophagy-activating kinase 1) pathway and an increase in autophagic flux. Overall, this work uncovers a new mitochondrial regulator that is required for axonal morphogenesis.

Purity is Not the Point
Authors: Ford Andrea Lilly
Published: May 2020

Environmental chemical toxicity evokes both individual action and relational interconnection. On the one hand, there is the diffusion of risk and harm through time and space, which complicates assigning fault, responsibility, or regulatory jurisdiction. On the other hand, toxicity begs the question of what individuals can do to feel a sense of agency and mitigate the damage done by daily necessities of living. I call this tension a double bind and suggest that it is mirrored by childbearing, arguing that childbearing offers a particularly compelling site for thinking through the possibilities and limits of consumer politics as a response to chemical toxicity. Childbearing and toxicity both disturb conventional ideas about individual actors in such a way that it makes the necessity of collective political action apparent even to those most invested in consumer politics. By building on new materialist philosophy and reproductive justice critiques of consumer choice, I consider both social and ontological problems with a politics based on individual agents. Ultimately, I argue that despite their flaws, consumer choices can be important acts of care alongside collective political action, and that childbearing can be a catalyst for ecological approaches to politics in which relations of responsibility and care are foregrounded.
Compost and Menstrual Blood
Authors: Vaughn Rachel
Published: May 2020

This article critically analyzes the afterlives of the sloughed uterine lining, the menses or period blood around which an entire ‘feminine products’ industry and waste management discourse has erupted. I engage ecological and green consumerism in the early 21st century as it both replicates and departs from discourses that frame the sloughed uterine lining and the products used to ‘manage’ it as disgusting and hazardous to human health, and as various actors seek to influence product sales or design as an attempt for menses to suit the goals of zero-waste. In centering my attention particularly on SWaCH’s Red Dot Campaign in Pune, India, I suggest that waste picker collectives especially are positioning themselves as important stakeholders, co-designers and necessary professional consultants on the product design of menstrual disposal technology. I ask what new insights might be gleaned by shifting attention away from consumption and waste management technology to center transnational grappling with what I elsewhere refer to as waste futurity, specifically menstrual waste’s futurity? Drawing upon a growing electronic archive produced by waste picker collectives in India, I center the expertise of those in the global disposal sector as they have represented their heterogeneous positions on their websites, mission statements, product sales, in public service media, interviews, and especially as one particular collective negotiates the validity of their gendered labor conditions and professional expertise in municipal zero-waste strategies. I expressly examine how workers harness revaluation in zero-waste strategies and in the futurity embedded in what is considered one of the most culturally abject of ‘wastes’—menstrual blood—to emphasize this notion of future vitality in the presumed dead, over, and impossibly useless.

Published: May 2020

Exercising is said to bring benefits to people taking part in, not only physical but also physiological gain. Heart Rate Variability (HRV) is an important marker reflecting the function of the autonomic nervous system (ANS), which has shown potentials in some exercise therapy and sport physiology studies. HRV analysis is said to be used for getting a better understanding of our body’s response to exercise and the reaction to different stressors from the workout. Thus, it is essential to monitor and optimize the recovery to avoid overtraining. This study aims to investigate the influence of HRV reflecting the physical stress level on participants when exercising, therefore, building a concept of self-training guide to improve the adaptation and performance. Electrocardiogram (ECG) is acquired by the BIOPAC system over 10 healthy college students during a proposed training protocol on the stationary bike, and post-exercising. HRV data from ECG is analyzed in time, frequency and nonlinear domains to extract various features to evaluate physiological recovery status, manage physical fatigue, intensity adjustment. From the evaluation of these indexes, participants are able to keep track of their physiological condition as well as to have more effective training exercises.

Published: May 2020

In recent years, oral problems are receiving more attention from not only experts but also almost people. If tooth lesions in the early stages, such as white spots, hidden dental caries, and tooth decay, etc., are not detected and treated promptly, they will lead to a risk of tooth loss. There are several common methods to detect tooth lesions such as clinical method, X-rays, and particularly near-infrared method, which is being developed significantly during the past decades. This method is substantially efficient for detecting early lesions by observing infrared images of tooth structures. In this study, near-infrared (NIR) light at 850 nm was used for detecting dental lesions. Enamel is nearly translucent in NIR light, so the lesions located under the enamel layer can be observed due to the interaction between NIR light and demineralized lesions. In addition, the NIR method is not only a safe method but also able to detect dental lesions at the early stage and tooth cracks which X-rays are limited to detect. In dentistry, an accurate diagnosis requires a combination of methods. Nowadays, X-rays are not only the common method but also the gold standard in dentistry, so this study incorporated clinical evaluation and X-rays to make the criteria for dental lesion diagnosis. This article has aimed to analyze and evaluate the effectiveness of the NIR imaging systems in detecting dental lesions and compare the NIR method to the clinical method combined with X-rays by Cohen's Kappa coefficient using SPSS (Statistical Package for the Social Sciences).

Published: May 2020

An interpolation technique-based meshfree method using polynomial functions is employed to analyze the static behavior of sandwich beams with functionally graded face sheets and homogenous softcore. Various beam theories are expressed in general form and taken into account both shear deformation and normal deformation effects. The governing equation is derived from the principle of virtual work. The obtained results have been verified with the previously published works and a good agreement is found. The effects of skin-core-skin thickness ratios, material volume fraction indices, slenderness ratios, shear deformation, and thickness stretching effect on deflection and axial stress are investigated and discussed.

Authors: Nguyen Ba Hung , Trinh Xuan Hoang
Published: May 2020

We used the tube model with Go-like potential for native contacts to study the folding transition of a designed three-helix bundle and a designed protein G-like structure. It is shown that both proteins in this model are two-state folders with a cooperative folding transition coincided with the collapse transition. We defined the transition states as protein conformations in a small region around the saddle point on a free energy surface with the energy and the conformational root-mean-square deviation (RMSD) from the native state as the coordinates. The transition state region on the free energy surface then was sampled by using the umbrella sampling technique. We show that the transition state ensemble is broad consisting of different conformations that have different folded and unfolded elements.

Vibration Effect on the Extracted Molecular Structure from Laser-Induced Electron Diffraction
Authors: Nguyen Thi Hien , Phan Thi Ngoc Loan
Published: May 2020

It is well-known that the laser-induced electron diffraction (LIED) contains molecular structural information that can be extracted with a spatial resolution of angström and time resolution of a few femtoseconds [1, 2]. The retrieval is based on the quantitative rescattering method (QRS) allowing the LIED signal to be split into two components [3], one of which is a laser-free differential cross-section (DCS) containing molecular structure. The method based on fitting the experimental DCS extracted from the LIED spectra to the theoretical DCS calculated with assumed initial structure parameters then allows one to reveal the real molecular structures. The theoretical DCS of molecules is treated within the independent atoms model (IAM) [1, 4] or the more advanced model based on the multiple scattering theory (MS) [2, 5].

In this report, we talk about how to consider the molecular vibration effect to the MS model and examine this effect of molecular vibrations on the DCS by comparing the oscillation component with the component of the MS second-order describing the interference of the scattering waves. We perform an application of the developed theory for some diatomic molecules.

In this paper, we investigate the linear perturbation of the material density of the universe in f(R) modified gravity of polynomial exponential form on the scale of distance below the cosmic horizon (sub-horizon). The results show that the model for the evolutionary aspects of the universe is slightly different from that in the standard cosmological model of ΛCDM. They can be used to show the difference between this modified gravitational model with the standard cosmological model of ΛCMD and other cosmological models. We also investigate the ration Ψ/ Φ and Geff / GN in the model and show that they are within allowable limits of experiments.

In the framework of the diagrammatic approach, the total cross section of near-threshold π– photoproduction on the deuteron is calculated. Contributions of the diagrams corresponding to the plane wave impulse approximation as well as to NN- and πN-interactions in the final state have been taken into account. We have compared the theoretical predictions with the results of the recent measurements performed at the MAX IV laboratory of the Lund University. There is good agreement with the data at photon energies from 147 to 155 MeV. However, at 158 and 160 MeV, the theoretical predictions significantly overestimate the measured cross sections.

Published: May 2020

The electrical characteristics of composite materials based on iron powders ASC 100.29 (Sweden) were investigated. The surface of powders is encapsulated by an insulating ferrite coating. The conductivity and the thermopower were studied, the cores were made by the pressing method, and then the samples were cut from the cores. The results show that the decrease in the electrical resistance with increasing temperature is due to a change in the contact between the grains in the sample. A change in the boundaries between grains (or domains) creates the conditions for formation of a new magnon, which affects the thermopower coefficient value. The research results can be used in the synthesis of composites with specified electromagnetic characteristics for practical applications.

The Walter-Harkness Health Plan, 1946-1956 in Nigeria identified Malaria as one the leading causes of morbidity and mortality in Nigeria. Even though that plan was truncated by the achievement of Self-Government by some parts of Nigeria in 1951, it is worrisome that some 70 years after, Malaria remains a leading cause of morbidity and mortality in all parts of Nigeria.

We have failed to consider the circumstances of our patients and those factors that make them repeat visits to health facilities for the same conditions over the years. If a mother brings the child to the health centre six times in a year for diarrhoeal disease, then we should reconsider our approach to the management of both mother and child or else we will soon lose that child to some complication of diarrhoeal disease.

Once disease sets in, individuals, families and communities are further impoverished. Conversely, disease exposes individuals, families and communities to poverty and ensures that they remain poor. We owe it a duty to our generation and those coming behind to begin to seriously apply those strategies that can effectively liberate our nation from the bondage of disease and poverty.

Gas emission in volcanic areas is one of the features that can be used for geothermal exploration and to monitor volcanic activity. Volcanic gases are usually emitted in permeable zones in geothermal fields. The use of thermal infrared radiometers (TIR) onboard of advanced spaceborne thermal emission and reflection radiometers (ASTER) aims to detect thermal anomalies at the ground surface related to gas emissions from permeable zones. The study area is located around Bandung Basin, West Java (Indonesia), particularly the Papandayan and Domas craters. This area was chosen because of the easily detected land surface temperature (LST) following emissivity and vegetation corrections (Tcveg). The ASTER TIR images used in this study were acquired by direct night and day observation, including observations made using visible to near-infrared radiometers (VNIR). Field measurements of volcanic gases composed of SO2 and CO2 were performed at three different zones for each of the craters. The measured SO2 concentration was found to be constant over time, but CO2 concentration showed some variation in the craters. We obtained results suggesting that SO2 gas measurements and Tcveg are highly correlated. At Papandayan crater, the SO2 gas concentration was 334.34 ppm and the Tcveg temperature was 35.67 °C,  results that are considered highly anomalous. The same correlation was also found at Domas crater, which showed an increased SO2 gas concentration of 35.39 ppm located at a high-anomaly Tcveg of 30.65 °C. Therefore, the ASTER TIR images have potential to identify volcanic gases as related to high Tcveg.

The Advanced Himawari Imager (AHI) is the sensor aboard the remote-sensing satellite Himawari-8 which records the Earth’s weather and land conditions every 10 minutes from a geostationary orbit. The imagery produced known as Himawari-8 has 16 bands which cover visible, near infrared, middle infrared and thermal infrared wavelength potentials to monitor forestry phenomena. One of these is forest/land fires, which frequently occur in Indonesia in the dry season. Himawari-8 can detect hotspots in thermal bands 5 and band 7 using absolute fire pixel (AFP) and possible fire pixel (PFP) algorithms. However, validation has not yet been conducted to assess the accuracy of this information. This study aims to validate hotspots identified from Himawari images based on information from Landsat 8 images, field surveys and burnout data. The methodology used to validate hotspots comprises AFP and PFP extraction, determining firespots from Landsat 8, buffering at 2 km from firespots, field surveys, burnout data, and calculation of accuracy. AFP and PFP hotspot validation of firespots from Landsat-8 is found to have higher accuracy than the other options. In using Himawari-8 hotspots to detect land/forest fires in Central Kalimantan, the AFP algorithm with 2km radius has accuracy of 51.33% while the PFP algorithm has accuracy of 27.62%.

On the basis of the two-channel remote measurement method previously developed at the Department of PES KGEU, a set of characteristics of the PD with the simultaneous use of electromagnetic and acoustic sensors, which allows you to remotely measure and evaluate the technical condition of high-voltage insulators (HVI). The article presents the results of developments in the development of the previously proposed method, which allowed to determine not only the type and location of the defect, but also its size and the degree of influence on the working condition of the VI. Particular attention is paid to the evolution of defects under the influence of overvoltage and other electrophysical processes in operating conditions. In particular, the generation of ultra-large PDs that can create erosion of the dielectric surfaces of defects was recently discovered, and the technical condition of highvoltage polymer insulators was examined. All measurements were performed on an experimental bench by non-contact receiving pulse signals of the PD by an electromagnetic tunable receiver in the range of 50-600 MHz. Their indication and computer processing were carried out in order to determine in each of the discrete intervals of the phase voltage the average values of the number and intensity of PD pulses, which either do not exceed the allowable threshold for the occurrence of defects and their development, in comparison with the reference HVI, or exceed it. Based on the results of preliminary bench tests on model specimens and real HVIs under operating conditions, and the obtained set of PD parameters, diagnostic signs were established that made it possible to determine the type, location of the most dangerous defects and the degree of their influence on the HVI working capacity. At the same time, the presence of the most dangerous defects is determined by the expansion of the phase intervals of PD radiation, a sharp increase in PD in negative half-periods of high voltage compared with positive half-periods, and also by a significant difference in the width and shape of single PD pulses.

The ACS150 frequency Converter was chosen as the object for experimental research. On the basis of the measurements it is concluded that in the spectral composition of current drawn by the frequency Converter, in addition to currents the main harmonic component is dominated by currents 5, 7, 11, 13, and 17th harmonics, i.e. harmonic components of odd non-multiple of three. Currents 3, 9 and 15 th harmonic components are also present in the spectral composition, but their value is much smaller. Also, based on the data obtained, it can be argued that with a decrease in the frequency of motor speed control and the load value of the frequency Converter, the number of pulsations on the current waveform increases, as a result, there is an increase in the values of the higher harmonic components and an increase in the value of the total harmonic components of the current. The main contribution to the increase in the index of the total harmonic components of the amperage with a decrease in the load of the frequency Converter and the output frequency of the motor speed control is made by odd harmonic components of the amperage multiple of three, at the same time harmonic components of the amperage non-multiple of three, namely the 5th and 7th order, are not subject to change. A brief review of technical solutions aimed at improving the electromagnetic compatibility of asynchronous frequency-controlled drive is given. In particular, such solutions as increasing the number of semiconductor switches used in inverters, improving control modes, the use of special separation transformers, passive (resonant) and active filters are noted.
