Authors: Gidayatova Margarita O. , Martynov Ilya D. , Yamshchikova Anastasia V. , Fleishman Arnold N.
Published: July 2021

Introduction. Polyneuropathy is the most common occupational neurological pathology. Violation of the activity of the central links of autonomic regulation due to excessive afferent impulses from the receptors of the skin and other tissues of the extremities leads to sympathetic activation and angiospasm, the progression of polyneuropathy. A decrease in the parasympathetic influence is the cause of systemic trophic disturbances. The possibility of transcranial magnetic stimulation of the prefrontal cortex opens up new therapeutic opportunities to correct the autonomic disorders in occupationally caused polyneuropathy. The aim of the study was to evaluate the effect of transcranial magnetic stimulation of the dorsolateral zone in the prefrontal cortex of the right hemisphere for the correction of neuroautonomic disorders in miners with polyneuropathy. Material and methods. Forty-two miners of the Kuzbass coal mines with a proven diagnosis of upper extremity polyneuropathy were examined. To identify autonomic dysregulation, the “Questionnaire for revealing the signs of autonomic changes”, spectral and nonlinear indices of cardio rhythm were used. Low-frequency (1 Hz) transcranial magnetic stimulation of the dorsolateral zone of the prefrontal cortex of the right hemisphere was performed in the course of 5 procedures according to a specially elaborated methodology. Results. In the examined miners, a decrease in the nonlinear and spectral indices of heart rate variability was initially determined, which indicated reducing adaptive capabilities, an increase in sympathetic influence. After the magnetic stimulation course, there was an improvement in general well-being and normalization of autonomous regulation according to the questionnaire. An increase in the spectral indices of the heart rate variability, more pronounced in the range of very low frequencies, indicated the activation of suprasegmental autonomic centers and an increase in parasympathetic influence. Conclusions. Transcranial magnetic stimulation of the prefrontal cortex effectively corrects autonomic disorders in miners with polyneuropathy and promotes an increase in adaptive capabilities due to the activation of suprasegmental autonomic centres.

Published: July 2021

Introduction. Working conditions at workplaces of coal industry enterprises are characterized by harmful factors exceeding the maximum permissible levels. These include coal-rock dust, noise, vibration, sudden temperature changes, etc. Conversely, unfavourable working conditions increase the risk of developing not only occupational but also work-related diseases. The objective of the study was to study the influence of industrial and common risk factors for cardiovascular diseases on structural and functional changes in the heart in coal industry workers. Material and methods. The study included 130 workers in coal mines in the South of Kuzbass and 78 workers in open coal pits, ranging from 40 to 55 years. The exclusion criteria from the study were the presence of any somatic pathology that could lead to structural and functional changes in the heart. In addition, all subjects underwent echocardiography to determine the structural and functional indices of the heart. Results. Lower values of ejection fraction and longitudinal deformation of the left ventricle were found among the workers in underground coal mining. At the same time, a decrease in the latter was revealed in 19.3% of the miners versus 7.6% of the workers in open coal pits (p=0.025). There was no association between reducing left ventricular longitudinal deformation and common risk factors in coal mine workers, in contrast, to open coal pit workers. The initial manifestations of diastolic dysfunction of the right ventricle in the group of workers of underground coal mining were revealed, which in the correlation analysis had a relationship with the indices of external respiration function. Conclusion. The decrease in the global longitudinal left ventricular myocardial deformation among miners is not associated with the studied common cardiovascular risk factors. Still, it is related to the influence of a complex of unfavourable production factors. Reduced indices of external respiration function affect the initial manifestations of diastolic dysfunction of the right ventricle in the workers of underground coal mining.

Published: July 2021

Introduction. Vibration disease is characterized by the early development of sensory polyneuropathy. Sensitive disorders significantly worsen the quality of life and increase the duration of the unemployable period of miners, which requires the search for new modern methods of correction and rehabilitation. Ischemic preconditioning is a promising direction in the treatment of occupationally caused polyneuropathies. However, its potential neuroprotective effect has not been sufficiently studied. The aim of the study was to evaluate the effectiveness of ischemic preconditioning of the upper extremities for the correction of sensory polyneuropathy manifestations in miners with vibration disease. Material and methods. Seventy-eight persons with a proven diagnosis of vibration disease were examined. According to a specially elaborated technique, the ischemic preconditioning of the upper extremities was performed in 46 patients who were included in the leading group; 32 patients made up the control group. The clinical and electroneuromyographic examination was carried out before the ischemic preconditioning procedure and on the 5th day of the study. Results. The initial clinical and neurophysiological indices in both groups did not differ statistically significant and indicated sensory polyneuropathy. After ischemic preconditioning, the subjects of the leading group showed an improvement in clinical and functional indices (reduction of numbness and paresthesia, improvement of vibration sensitivity, an increase in the sensory conduction velocity of impulse and the amplitudes of sensory responses) of the peripheral nerves of the upper extremities. In contrast, in the control group, there was no statistically significant change in objective indices. Conclusion. Ischemic preconditioning of the upper extremities is effective in the rehabilitation of miners with vibration disease, helps to reduce the manifestations of sensory polyneuropathy, sensitive disorders and normalize neurophysiological indices.

Published: July 2021

Introduction. Patients with vibration disease (VD) often have obesity and metabolic syndrome (MS), which increase the risk of developing type 2 diabetes, hypertension, and other conditions predisposing to a decrease in the quality and longevity of life. Genetic predisposition, overnutrition, environmental factors, including industrial ones, and others are factors influencing the formation of MS. The aim of the study is to identify associations between polymorphisms of the LEPR, PPARG and PPARGC1A genes, metabolic syndrome and obesity in VD patients caused by exposure to local vibration and the combined effects of local and general vibration. Material and methods. We examined 248 VD male patients exposed to local vibration and the combined impact of the local and general vibration. We have identified a subgroup of MS and obesity cases. The distribution of genotypes of the LEPR, PPARG and PPARGC1A genes in groups was studied. Results. In the group of VD and MS patients exposed to the combined effect of local and general vibration, the Gln/Gln genotype of the Arg223Gln polymorphic locus of the LEPR gene was less common, and the Arg / Gln genotype in MS cases was detected more often than in patients without it. Among patients with VD caused by exposure to local vibration with a waist circumference of more than 102 cm, the Gly / Ser genotype of the Gly482Ser polymorphism of the PPARGC1A gene was more common than among those with lower values of this indicator. Conclusion. In patients with VD caused by combined exposure to local and general vibration, the Gln/Gln genotype carrier of the Arg223Gln polymorphism of the LEPR gene may play a protective role in the formation of MS. Among individuals with VD caused by exposure to local vibration, carriers of the heterozygous genotype of the Gly482Ser polymorphism of the PPARGC1A gene may have a predisposition to the development of obesity. The obtained results are preliminary and require further research.

Introduction. Dried fruits are a valuable source of dietary fibre, many vitamins and minerals in the population’s diet. However, the high content of readily available carbohydrates makes this type of product vulnerable to mould contamination. The greatest danger among which are toxigenic species. But there is practically no scientific information about the contamination presented on the Russian market dried fruits with moulds producing mycotoxins. That does not allow judging about this aspect of food safety. Materials and methods. Contamination with moulds and bacteria of 57 samples of dried fruits of 7 species popular in Russia was studied using cultural methods of analysis. Monospore isolates of moulds were isolated from dried fruits; in vitro mycotoxins production studied; by UHPLC-MS / MS analyzed mycotoxins in the multidetection mode. Results and discussion. In general, the microbial contamination of dried fruits was low: 87.7% of the samples met the established microbiological standards, in most cases, moulds caused it. At the same time, the highest frequency and levels of contamination were found in dates. Aspergillus sp. dominated in the micoflora of all types of dried fruits. Among the isolated 33 strains of moulds, 45.5% turned out to be toxigenic and, in vitro, were capable of biosynthesis of significant amounts of several types of mycotoxins, including emergent mycotoxins. Fumonisin- and ochratoxin-producing activities have been found in Aspergillus strains of the Nigri section. In model experiments, the accumulation of mycotoxins in individual strains exceeded the level normalized in grain products, including (in μg/kg): for aflatoxins B1 - more than 32000 and B2 - 3230; fumonisin B2 - more than 3100; ochratoxin A up to 4.3; for emergent accumulation reached: sterigmatocystin up to 6218220 and citreoviridine - 153. Conclusion. Moulds are the main type of microflora that contaminates dried fruits. The ability of mould isolates from dried fruits to form mycotoxins has been established, among which highly toxigenic strains have been identified. This indicates the presence of a potential risk of contamination of this type of food with unregulated mycotoxins and a possible increase in their content in the diets of consumers. The results obtained substantiate the need for extensive monitoring of mycotoxin producers in dried fruits. This is important for predicting the risk of toxin formation and identifying the relationship of specific mycotoxins with certain types of dried fruits. The presence of toxigenic activity of moulds isolated from dried fruits has been shown in Russia for the first time.

Published: July 2021

Introduction. The bacterial reverse gene mutations test (the Ames test) is widely used to assess chemicals’ mutagenic activity. The spontaneous mutation level of test strains is a mandatory characteristic that has to be monitored in a laboratory performing mutagenicity studies using the Ames test. In this regard, it is important to assess the factors affecting the spontaneous mutation level in the experiment and, therefore, on the general conclusion on the test item mutagenicity. Material and methods. A plate incorporation test version was used both in the presence and absence of a metabolic activation system. Results. We summarized the historical control data obtained in the laboratory in 2016-2020, determine the fluctuation limits in the number of revertant colonies for each strain, and identify the factors affecting the negative control variability. No significant differences were found in the spontaneous background of test strains when using DMSO or water as solvents, polypropylene or polystyrene tubes, as well as Petri dishes of different types. In the case of the TA1535, TA102 and TA100 cultures, no influence of the presence of the S9 mixture on the spontaneous reversion range was revealed (p≤0.05). Statistically significant differences in the number of spontaneous revertants (at + S9 or -S9) were found for the strains that allow detecting frameshift mutations, TA97 and TA98. It has been shown that the volume of the selective medium and the brand of gelling agent in its composition are important factors leading to the variability of the historical negative control. Conclusion. To ensure the quality of experiments according to the principles of good laboratory practice and the reliability of the data obtained using the bacterial reverse mutation method, it is necessary to standardize the operations in advance of experiments.

INVENTORY DECISION IN VUCA WORLD USING ECONOMIC LOGIC QUANTITY
Authors: Vesa Lidia , Bolos Marcel Ioan , Sabău-Popa Claudia Diana
Published: July 2021

If ever the concept “VUCA” (Volatility, Uncertainty, Complexity, and Ambiguity) seemed appropriate to use, it is now. National and global companies experience the highest level of instability due to the Covid-19 pandemic, which is the classic example of a highly volatile, uncertain, complex, and ambiguous world. In this world, decision-makers have to face more challenges appealing to the VUCA Prime leadership approach: vision against volatility, understanding against uncertainty, clarity against complexity, and agility against ambiguity. Some of the ways through which managers can overcome the VUCA characteristics include: providing a shared vision as a criterion for all decisions to be made, identifying the reason for the decision problems and sharing the idea with the followers, going through the entire decision process, following steps in proper order, and developing quick solutions. In an inventory decision taken in a VUCA context, the above ways are possible if using fuzzy inventory methods dealing with volatility, uncertainty, complexity, and ambiguity. This paper aims to adapt a traditional inventory method, Economic Production Quantity (EPQ), to the challenges of the VUCA world, through the fuzzy logic system (FLS). To achieve the best solution for the decision problem in the shortest time possible, the managers can employ a conversion by using the computing platform MATLAB. There are some advantages of this conversion for these two methods, EPQ and FLS. Firstly, the transformation of EPQ in ELQ (Economic Logic Quantity) allows managers to formulate the decision problem, even if they cannot identify and measure precisely the EPQ parameters. Secondly, using FLS to solve ELQ provides the possibility to simulate more alternatives and generate the solution in the shortest amount of time. Thirdly, it allows the decision-makers to evaluate the impact of the solution provided by each simulation on the company’s performance. Using these methods has the following primary limit: the problem formulation step depends on the managers’ understanding ability and managing a large volume of information. Therefore, there may be a risk of obtaining a relevant solution for a decision problem if the decision-makers do not understand the cause of the problem or do not know how to organize and manage a large volume of information. This limit could be overcome by using AHP (Analytic Hierarchy Process), but this is the topic of further research.
CONSUMPTION EXPENDITURE OF THE ELDERLY IN THE EUROPEAN UNION: CONVERGENCE AND IMPACT ON GDP
Authors: Anca Sanda
Published: July 2021

In the context of an ageing population, the aim of this study is to analyze how the consumption expenditure of the age group 50 plus affected the GDP growth rate during the period 2005-2019, at the level of the European Union countries. Using spatial econometrics, we study the convergence process of both the consumption expenditure of the 50 plus age group and the GDP. Furthermore, we analyze the relationship between the two variables and its evolution in time. We conclude that there is a bidirectional relationship between the studied variables: an increase in the growth rate of the 50 plus age consumption significantly and positively impacts the GDP growth rate and vice versa. At the level of Western European states where the share of 50 plus population is the highest, the impact on GDP growth rate is stronger. The results are relevant for further identifying possible economic opportunities created by the ageing population while supporting the European Union cohesion policy through the convergence process aimed at reaching an overall harmonious development within the member states and regions.

A hydraulic press is a device (see machine press) using a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. A hydraulic press is a machine using a hydraulic cylinder to generate a compressive force. Frame, hydraulic cylinder and press table are the main components of the hydraulic press. Hence a hydraulic press is a machine that makes use of the pressure exerted on the fluids to crush, straighten or mould. The concept of the hydraulic press is based on Pascal's theory, which states that when pressure is applied on fluids in an enclosed system, the pressure throughout the system always remains constant. In hydraulic press, the force generation, transmission and amplification are achieved using fluid under pressure. The liquid system exhibits the characteristics of a solid and provides a very positive and rigid medium of power transmission and amplification. In a simple application, a smaller piston transfers fluid under high pressure to a cylinder having a larger piston area, thus amplifying the force. There is easy transmissibility of large amount of energy with practically unlimited force amplification.

In Numerical Analysis and various uses, including operation testing and processing, Newton’s method may be a fundamental technique. We research the history of the methodology, its core theories, the outcomes of integration, changes, they’re worldwide actions. We consider process implementations for various groups of optimization issues, like unrestrained optimization, problems limited by equality, convex programming, and methods for interior points. Some extensions are quickly addressed (non-smooth concerns, continuous analogue, Smale’s effect, etc.), whereas some others are presented in additional depth (e.g., variations of the worldwide convergence method). The numerical analysis highlights the quicker convergence of Newton’s approach obtained with this update. This updated sort of Newton-Raphson is comparatively straightforward and reliable; it’d be more probable to converge into an answer than either the upper order strategies (4th and 6th degree) or the tactic of Newton itself. Our dissertation could be about the Convergence of the Newton-Raphson Method which is a way to quickly find an honest approximation for the basis of a real-valued function g(m) = 0. The derivation of the Newton Raphson formula, examples, uses, advantages, and downwards of the Newton Raphson Method has also been discussed during this dissertation.

Water is resuscitative to the life cycle and the provision of drinking water; it can hardly be overcome in the current years. The defiance for human beings currently faces filtered water and the lack of renewable energy. Solar energy is an undesirable way of converting palpable water into freshwater using extraordinary energy sources that are readily obtainable on marl. The main problem with the conventional basin is still that the production is very insignificant. The most notable design parameters that influence productivity are the optimization of solar radiation, evaporation area, and water temperature. This paper intentions to give a comprehensive review about that the coalition of appropriate solar stills or improved designs that can favor the solar energy heat gain improves the overall performance of the system. Constructed on the current approach, a perspective conclusion has been made after the rich discussion with the help of distinctive information about the systems.

Spice oils are known to exhibit antifungal activity and therefore have the potential to control mycotoxin production. There is a need in the food industry to find measures to control mycotoxins that are frequently associated with grains that form the staple diet of the majority of the population in South Africa. Clove, cinnamon, oregano, tumeric, eucalyptus, neem, aniseed, mace and nutmeg oils were tested to determine their inhibitory potential against growth of Aspergillus parasiticus and Fusarium moniliforme using the agar overlay technique. Varying concentrations of the spice oils, ranging from 0.1 ppm to 2.0 ppm, were incorporated into broth cultures of A. parasiticus and maize patty cultures ofF. moniliforme. Levels of production of aflatoxins and fumonisin were determined using standard thin layer chromatography and highpressure liquid chromatography methods. In addition, the active component of the spice oils were isolated, characterised and tested. The inhibitory potential of these compounds for field use was tested by incorporating clove oil, whole cloves and ground cloves in samp

Information Technology is so widespread and moving at such a rapid speed that it has influenced the education sector at a fast and pressurised pace. This influence has placed focus on the new terminology education technology and blended learning. In order to introduce and implement education technology, Higher Education Institutions (HEIs) worldwide have been introducing Learning Management Systems (LMSs) to support the charges in pedagogy to improve the collaboration learners themselves and between learners and educators. The implementation of LMSs at South African HEIs are still lagging behind in comparison to first world countries. Nonetheless, changes and advances in education technology have been taking place. These changes have to some degree brought about resistance towards the use of technology (software) to change teaching technique. Mixed methods research (quantitative and qualitative) was used to conduct a case study analysis at the Durban University of Technology (the case of DUT academic staff using a LMS). The case study allowed the analysis of perceived ease of use (PEOU) of LMSs at this HEI. The perceptions of the academic staff was analysed by executing a survey and by conducting interviews. The study identified additional factors that have a significant influence on PEOU on the Technology Acceptance Model 3 (TAM) (Venkatesh and Bala 2008). Literature, information from the interviews and the themes that emerged from the qualitative results was used to propose a theoretical tiered pedagogical framework that could be adopted by other HEIs planning to adopt a LMS.
