Introduction. The problems of the impact of endocrine disruptors on human health and the environment are of serious concern today at the international, regional and national levels. Although the first mention about an ability of a substance to harm the endocrine system back in the 60 th of the XX century, the issues of substantiating the criteria for classifying it as endocrine disruptors, identifying potential disruptors of the endocrine system, assessing and classifying their danger to health and the environment with the purpose of further regulation. The aim of the study. To study of world experience in classifying chemical compounds as endocrine disruptors; creating a list of chemicals circulating on the territory of the Russian Federation that can potentially affect the endocrine system; selection of criteria for their classification according to the degree of hazard. The material for the analysis was literature sources from the bibliographic databases Web of Science, MedLine, EMBASE, Global Health, PubMed, Scopus, RSCI. The documents of international organizations, the European Union, the USA, Canada, Japan, India and other states on the hazard assessment, classification and regulation of endocrine disruptors have been studied and analyzed. Considering international experience, the criteria for classifying chemical compounds as endocrine disruptors have been substantiated, including three main components: an adverse effect on the body, an endocrine mechanism of action, and a biological relationship between endocrine activity and an adverse effect. A comparative analysis of the hazard classifications of endocrine disruptors developed by the EU and India showed to be based on the principles of the Globally Harmonized System of Classification and Labeling of Hazards of Chemicals and Mixtures. Considering the limited scientific knowledge about substances capable of destroying the endocrine system, it is advisable to introduce class 3 for substances with limited data obtained in “in vitro” experiments in invertebrates tests. Conclusion. International approaches to the selection, assessment and classification of chemicals that have a potential impact on the endocrine system will allow for the first time in the Russian Federation to form a national list of endocrine disruptors, to identify substances that are the priority in terms of hazard and degree of risk for making relevant management decisions.

Published: January 2022

Introduction. Vibration is one of the leading unfavourable physical factors of the working environment and leads to vibration disease (VD) development. The study of metabolic profiles of markers of fatty acids (FA) metabolism is one of the directions in the early diagnosis of vascular diseases and metabolic syndrome (MS), caused, among other things, by exposure to vibration. The aim of this work is to study the spectrum of esterified fatty acids of the omega-3 and omega-6 families in the blood of patients with vibration disease (VD) and combination with metabolic syndrome (MS). Materials and methods. The study involved 66 people, divided into two groups: Group I - 34 patients with an established diagnosis of VD; Group II - 32 patients with an established diagnosis of VD in combination with metabolic syndrome (MS). The levels of esterified forms (EF) of polyunsaturated fatty acids (PUFA) of the ω-3 and ω-6 families in blood plasma samples were determined using the method of gas chromatography-mass spectrometry on an Agilent 7890A gas chromatograph with an Agilent 5975C mass selective detector. Results. The distribution of quantitative indices of PUFA of the ω-3 and ω-6 families in the examined groups was studied. In VD patients with MS, compared with VD patients, there was a statistically significant increase in the level of eicosapentaenoic, α-linolenic acids of the ω-3 family, the sum of ω-3 PUFAs, γ-linolenic and linoleic acids of the ω-6 family. Conclusion. The study of the quantitative indices of EF of the families ω-3 and ω-6 in the blood plasma of VD patients with MS showed the levels of ω-6 to be 4.5-5.4 times statistically higher than the levels of ω-3 fatty acids.

Authors: Leshchenko Yaroslav A. , Lisovtsov Aleksandr A.
Published: January 2022

Introduction. The concepts of the epidemiological transition and types of population health are applied to analyzing and evaluating the sanitary and epidemiological status of the population. Materials and methods. For many years of mortality, the dynamics of the male population of the Irkutsk region standardized indicators were used (European age standard). For identifying trends of changing mortality rates, an analytical alignment of the time series was used. It was a linear model by EXCEL’s standard tools (Microsoft Office 2007). The significance of the trend equation was calculated using F-test in IBM SPSS Statistics 23 (p < 0,05). Results. It has been established that the formation of various types of pathology and caused by this pathology mortality occurred under the influence of factors of different nature in the process of changes in social, environmental, epidemiological situations in the region. In the 1990 th and the first half of the 2000 th, high mortality rates in the class of diseases of the circulatory system and the class of external causes of morbidity and mortality were determined mainly by psychosocial disadvantage factors. By the class of Diseases of the respiratory system, there was noted a steady decrease in mortality rate from chronic diseases of the lower respiratory tract and pneumonia. It was probably due to an increase in the level and quality of medical care. A steady tendency to increase intensive and extensive mortality rates by class of Certain infectious and parasitic diseases was seen. That was caused by negative changes in infectious and epidemic processes under the influence of man-made pollution was noted. During 2005 - 2015 the digestive system’s share of the class of Diseases in the mortality structure increased. That is due to the prevalence of alcoholic liver disease, chronic alcoholic pancreatitis, complications of the ulcer of the stomach and duodenum. Conclusion. The combination of the identified patterns of the formation of intensive and extensive mortality rates determined by exogenous and endogenous factors made it possible to characterize the situation in the Irkutsk region as a relative sanitary and epidemiological disadvantage of the population.

Introduction. Over the past two decades, a large amount of data has been accumulated that show the significant impact of social factors on the health of the population. The Republic of Bashkortostan is a large industrial centre and one of the most promising subjects of the Russian Federation. Purpose of the study. Ranking the territories of the Republic of Bashkortostan by priority socioeconomic indices, as well as determining their impact on the health of the child population. Material and methods. As the initial data, the materials of the socioeconomic state of the Republic of Bashkortostan, data on the number and morbidity of the child population for the period 2014-2018 were used. Correlation-regression analysis was carried out, and qualitative assessments of the results obtained were given. The principle of dividing the territory into seven socio-economic zones, taking into account climatic and geographical features, the development of industrial potential and the existing socio-economic ties, was chosen as the basis for the study. Results. The ranking of territories by socio-economic indices in the Republic of Bashkortostan showed that most of the municipalities (over 60%) have a low level of socio-economic development. The most favourable conditions in terms of social comfort for children were found in the southern, central and northwestern economic zones. So, as socio-economic indices improve by 2018, the incidence of the population tends to decrease. Conclusion. Thanks to the data obtained, a number of the most disadvantaged areas in socio-economic development and morbidity in the child population have been identified. In these territories, it is recommended to develop a set of measures to improve and stabilise socio-economic indices.

Published: January 2022

A review of the available domestic and foreign literary sources is presented concerning factors affecting the working capacity of persons after coronary artery bypass grafting. It was found that in Russia, after surgical treatment of coronary heart disease, there is an increase in the number of disabled people compared to foreign data. In recent years, there has been an increase in patients undergoing coronary bypass surgery. However, this did not reduce the increasing number of disabled people after coronary artery bypass grafting, which does not correspond to the initial expectations about the cost-effectiveness of this type of surgery. According to Russian researchers, the proportion of persons with disabilities referred for surgical myocardial revascularization was 39.0-42.5%. Subsequently, this indicator increased to 64.0%. In other countries, the dynamics are different. Among patients under 60 years of age who underwent surgical treatment of coronary artery disease, more than half returned to work. In general, labour activity was restored by 67.5%, and the number of disabled persons decreased from 56.0 to 42.0%. Social and medical factors were assessed to establish the causes of disability after coronary artery bypass grafting. World experience testifies to the critical role of state social support in preserving the labour status of patients, which ultimately justifies the economic costs of surgical treatment. To assess the degree of disability after coronary artery bypass grafting, social status before surgical treatment of coronary heart disease, and the severity of comorbid pathology. To increase the economic efficiency of coronary bypass surgery, it is necessary to organize an affordable and effective rehabilitation program, uniform criteria for referring patients to medical and social expertise.

THE SOCIAL VALUES ATTACHED TO THE TIKTOK SOCIAL PLATFORM OF THE AGE CATEGORY 50+. A SOCIOLOGICAL PERSPECTIVE
Authors: ȚĂRUȘ LORENA
Published: January 2022

This paper analyzes the social values through which users over the age of 50 identify with the new TikTok social platform. Although the other online social networks are mainly aimed at a young audience, the TikTok application has overcome this barrier and included the age segment of over 50 years in the categories targeted by it. The ease with which one can make their proper creations and the intuitiveness of the application has made that two years after the launch of the new social platform a quarter of its users are in a more tangible age category of novelty and online interaction. The reality shows that a social application does not contradict people from early youth at all, and if you provide them with sufficiently clear tools to express themselves, they will take advantage of them and make their genuine creations.

The present approach is based on existing data about the application in question and focuses on illustrating some values that emerge from the case study on TikTok.
Objective method for analysis of mineral resources supply
on the example of Russia
Authors: Egorova Irina , Mikhailov Boris
Published: January 2022

A forecast of nonfuel mineral production in Russia is

considered, based on the integration of the expected life

of specific deposits currently exploited and developed. It

is shown that mineral safety is fully ensured for copper,

nickel, lead, tungsten and tin, whose reserves are sufficient

for their extraction, at least at the current level, for

40–50 years and there are real prospects for its significant

growth. The sufficiency of other minerals is much

lower: for molybdenum and chromium, it is limited to

about 30 years, and the extraction of zinc and uranium

in Russia may significantly decrease in 20 years. The situation

is more difficult with the most liquid solid minerals,

like gold and diamonds. The commissioning of mining

enterprises at the developed gold deposits can ensure

a rapid growth in the production of the precious

metal in the coming years. However, at the beginning of

the next decade, the resource base depletion of the Olimpiada

field and a number of other exploited deposits is

predicted. The projects currently implemented for the

development of new fields do not compensate for the lost

capacity. This may account for a long-term (until the beginning

of the 2050s) decline in the Russian gold production,

which may be halved against the current level by

the end of this period. Such a scenario can only be avoided

with the intensification of geological exploration in

the coming years. The earlier decrease in the number of

diamonds mined in Russia, associated with the depletion

of reserves of exploited pipes, is predicted (since 2025).

Unless new deposits are discovered and developed, the

domestic production of precious stones will steadily decline

and, in the 2040s, may be reduced fourfold.

Published: January 2022

This paper proposes a novel compact, single structure, multi-band antenna along with tested results for wireless local area networks (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications. In this work, modified complementary split-ring resonators (CSRR) were incorporated in the ground layer of the patch to achieve permeable bands to accommodate multi-resonance frequencies in a single device. The proposed antenna design supported the upgraded performance and led to desirable size reduction. Open stubs were incorporated at the edges of the triangle batch to get the improved reflection coefficient responses. It resulted in specific band spectra of 2.4 / 3.4 / 5.1 / 5.8GHz for WLAN/WiMAX applications. For constructive antenna design, CST microwave studio simulation software was utilized. S11 parameter was observed as -24dB at 2.4GHZ, -32dB at 3.4GHz. -15dB at 5.1GHz and -22dB at 5.8GHz bands. Field patterns of each band were observed. The parametric study of the arrangement and positioning of the CSRR unit cell was examined. Excellent consistency between the experimental and simulated results revealed the capability of the projected structure to perform with improved gain.
Sliding Window and Parallel LSTM with Attention and CNN for Sentence Alignment on Low-Resource Languages
Authors: Tan Tien-Ping , Lim Chai Kim , Abdul Rahman Wan Rose Eliza
Published: January 2022

A parallel text corpus is an important resource for building a machine translation (MT) system. Existing resources such as translated documents, bilingual dictionaries, and translated subtitles are excellent resources for constructing parallel text corpus. A sentence alignment algorithm automatically aligns source sentences and target sentences because manual sentence alignment is resource-intensive. Over the years, sentence alignment approaches have improved from sentence length heuristics to statistical lexical models to deep neural networks. Solving the alignment problem as a classification problem is interesting as classification is the core of machine learning. This paper proposes a parallel long-short-term memory with attention and convolutional neural network (parallel LSTM+Attention+CNN) for classifying two sentences as parallel or non-parallel sentences. A sliding window approach is also proposed with the classifier to align sentences in the source and target languages. The proposed approach was compared with three classifiers, namely the feedforward neural network, CNN, and bi-directional LSTM. It is also compared with the BleuAlign sentence alignment system. The classification accuracy of these models was evaluated using Malay-English parallel text corpus and UN French-English parallel text corpus. The Malay-English sentence alignment performance was then evaluated using research documents and the very challenging Classical Malay-English document. The proposed classifier obtained more than 80% accuracy in categorizing parallel/non-parallel sentences with a model built using only five thousand training parallel sentences. It has a higher sentence alignment accuracy than other baseline systems.

Published: January 2022

Having a system to process and store information securely is crucial for an e-learning environment in a higher learning institute. Data recorded manually is deemed unsuitable as it may lead to mishandling of documents, poor record of documents movements, and even missing documents. A final year project (FYP) subject for a particular university’s course would need a specific management system to alleviate the work processes of supervision and monitor student progress. This system would reduce cost, paperwork, staffing and even simplify the workflow process. Therefore, introducing a student dashboard-based system for the FYP course is proposed in this study. This paper presents a smart system utilizing data analytics and a dashboard that enables the students to self-monitor, track progress and manage important information related to their FYP. The system development followed stepwise Rapid Application Development (RAD) methodology in developing the system. The developed system has been designed, developed, and tested by university students taking FYP courses. A Technology Acceptance Model (TAM) was adopted in the testing phase to examine the system acceptance and user behavior intention in using the proposed system. The results showed a significant effect on a positive implementation in the faculty’s course management and monitoring the student’s FYP progress. For the dashboard-based system to reach its full potential, it is highly recommended to implement the system in its course management fully.

Published: January 2022

In this study, the biomass of banana peel was used to produce pectinase via optimization of solid-state fermentation conditions of the filamentous fungi Aspergillus nigeA. niger). The operating conditions of solid-state fermentation were optimized using the method of full factorial design with incubation temperature ranging between 25 °C and 35 °C, moisture content between 40% and 60%, and inoculum size between 1.6 x 106 spores/mL and 1.4 x 107 spores/mL. Optimizing the solid-state fermentation conditions appeared crucial to minimize the sample used in this experimental design and determine the significant correlation between the operating conditions. A relatively high maximal pectinase production of 27 UmL-1 was attained at 35° C of incubation, 60% of moisture content, and 1.6 x 106 spores/mL of inoculum size with a relatively low amount of substrate (5 g). Given that the production of pectinase with other substrates (e.g., pineapple waste, lemon peel, cassava waste, and wheat bran) generally ranges between 3 U/mL and 16 U/mL (Abdullah et al., 2018; Handa et al., 2016; Melnichuk et al., 2020; Thangaratham and Manimegalai, 2014; Salim et al., 2017), thus the yield of pectinase derived from the banana peel in this study (27 U/mL) was considered moderately high. The findings of this study indicated that the biomass of banana peel would be a potential substrate for pectinase production via the solid-state fermentation of A. niger.

Published: January 2022

Steel is extensively used in many applications that include construction because of its unique properties and the ease with which its properties can be enhancedfor improved performance. Due to its high malleability and strength, it can be easily machined and welded compared to other types of steel. However, the susceptibility to low performance has been associated with its low resistance to environmental degradation when exposed to corrosive or polluted environments. This study focuses on mild steel heat treatment quenched in four mediums of engine oil, water, palm oil, and air, along with its properties and corrosion susceptibility. The high temperature used for the procedure is 800 °C, 900 °C, and 1000 °C, respectively. After the heat treatment procedure, the test samples undergo corrosion testing in the sodium chloride solution for two weeks to observe the presence of corrosion products rust on its surface. The tensile machine was utilized to obtain the mechanical properties, including yield strength, tensile strength, and percentage elongation. The hardness values were obtained using the Rockwell hardness machine, and the optical microscope (OM) was used to observe the effect of the corrosion activity on the sample surface. The results obtained indicate an increase in the hardness, yield, and tensile strength, but the elongation reduces as the temperature increases.

Published: January 2022

Engineered Cementitious Composites (ECC) have become another alternative in the concrete industry due to their excellent strain capacity under uniaxial tension. Research and development for new ECC mix incorporating wastes remain open to fulfil the industrial needs to produce green and sustainable ECCs. This paper presents the experimental work on the tensile and cracking behaviour of ECCs utilising industrial waste, namely ground granulated blast-furnace slag (GGBS), to replace cement. A total of four slag-based ECC mixes containing 2%–2.5% of PVA fibres and 50%-60% GGBS were investigated under uniaxial compressive and tensile tests. Compressive strength, tensile strength and the crack behaviours of the slag-based ECCs were evaluated and compared with a control mix. The experimental results show that the slag-based ECCs can achieve tensile strain capacity 2.6 %–2.75 % and ultimate tensile strength 1.43 MPa–2.82 MPa at 28 days. It was also found that the ECCs with GGBS and fibres formed few hairline cracks at the gage of the dog bone compared to brittle fracture in the control specimens.

This study investigates CNT-doped Cu2O thin film deposited by spray pyrolysis technique at a substrate temperature of 100°C. The samples were annealed at temperatures of 200°C and 230°C for 30 minutes. The effect of CNT doping on certain optical properties, such as extinction and absorption coefficients, a refractive index of doped Cu2O thin films were examined. The absorbance of the doped samples increases within the visible range and decreases in the ultraviolet range of the electromagnetic spectrum (EM). Both absorbance and extinction coefficients increased with temperature making the samples a good candidate for use as absorbance layer in device fabrication. In addition, there was an increase in direct bandgap with the increase in CNT concentration of the thin films. The result of the study revealed that CNT doping has a significant effect on the properties of Cu2O.

This paper proposes a dataset consisting of 34200 images of twelve different high medicinal value local perennial herbs in Malaysia. The images were captured under various imaging conditions, such as different scales, illuminations, and angles. It will enable larger interclass and intraclass variability, creating abundant opportunities for new findings in leaf classification. The complexity of the dataset is investigated through automatic classification using several high-performance deep learning algorithms. The experiment results showed that the dataset creates more opportunities for advanced classification research due to the complexity of the images.

Published: January 2022

A computational study was performed to analyze the airflow over bio-inspired corrugated wings. The bio-inspired corrugated wing profiles were derived from the mid-span section of the forewing of Aeshna Cyanea dragonfly species. Additionally, a hybrid non-corrugated profile was also created possessing geometric similarities with the corrugated airfoils to compare and visualize the effects of corrugation on the fluid flow. The computational analysis was conducted for 4,8-, and 12-degrees angles of attack. Streamlines obtained from the computational analysis results (carried out on ANSYS CFX) showed the formation of secondary flows or vortices that are trapped in the valleys of the corrugated wings which was not observed in the hybrid airfoil. This study also compares the effects of corrugation geometry on fluid flow behavior. It was also seen that the intensity and quantity of the secondary flows increased with the increase in the angle of attack.

This study investigates the viscous skin friction drag generation due to the three different vertical canard locations on the mid winger un-swept aircraft scaled-down model by using boundary layer measurements in the wind tunnel. The N22 airfoil was selected for the canard and the modified S1223 airfoil was selected for the wing. The laser cutting technique was employed for the fabrication of the wing, and canard airfoils, which gave sufficient dimensional accuracy to the model. The canard, wing, and fuselage were fabricated by balsa wood and strengthened by Aluminum stripes. The assembled model is tested in an open subsonic wind tunnel a fixed chord Reynolds number 3.8*106. The boundary layers were measured at 70% of the chord and at three different wingspan locations i.e. 30%, 60%, and 90% with 00 incidence angle. The canards were positioned at three vertical positions one at fuselage reference line (FRL) and the remaining two locations at ± 0.16 c from the FRL. The results were compared with wing-body alone and with three canard locations and found that the high canard configuration outperformed the other two configurations and also wing-body alone configuration as it provides half of the total drag. However, the high canard produces 15% more drag than the wing-body alone at the wing tip (90%).The aerodynamic performance of the high canard configuration was found to be significantly promising for the future use in drones and other small aircrafts.

Published: January 2022

The detection and identification of wood-rotting fungi in standing trees is crucial for the prediction of the severity and evolution of decay. In the case of very active root and butt rot fungi, an early identification method is important to establish the more appropriate failure risk classification. This work is aimed at reviewing the biomolecular methods recently developed to identify, directly from wood, some of the most important and widespread decay fungi. The whole method is based on the use of taxonspecific primers combined in five multiplex polymerase chain reactions (PCRs). Three multiplex PCRs allow identifying Armillaria, Ganoderma, Hericium, Inonotus, Laetiporus sulphureus, Perenniporia fraxinea, Phellinus, Pleurotus, Schizophyllum, Stereum, Trametes, and Ustulina deusta. The two remaining multiplex PCRs were developed for subgeneric identification of fungi belonging to Ganoderma, Inonotus, and Phellinus. In validation assays, multiplex PCRs allowed successfully detecting fungi in 83% of wood samples collected from decay-affected trees. Thus, the methods proved to be efficient and specific for the diagnosis and the early detection of decay fungi on standing trees.
Residual Strength of Carabiners Used by Tree Climbers
Authors: Kane Brian , Dennis Ryan H.
Published: January 2022

Tree climbers increasingly use carabiners and apply them in situations for which they are not designed. Because failure of carabiners can result in serious injury or death, the following study tested how well carabiners endure the stress to which climbers subject them. This study distributed carabiners of four types (all manufactured by Petzl) to climbers in Massachusetts and New York, USA, and collected them a year later. Then, carabiners were broken in a universal testing machine and measured the maximum load, as well as surface roughness. No carabiners broke below their rated strength; and used carabiners were, with one exception, as strong as new carabiners. Surface roughness was a weak, but significant, predictor of strength. Findings are discussed in light of climber safety and the importance of conducting long-term studies.
