Authors:   Azerbaijan State Oil and Industry University, Shirinova D.B. , Bayramova A.S. ,   Azerbaijan State Oil and Industry University
Published: March 2023

The process was carried out on an environmentally clean separator device of a new type-a classifier. The technological parameters of the process, the geometric parameters of the installation are determined and the influence of changes in these parameters on the course of the technological process is studied. It is established that in a pneumatic classifier with a multistage, cylindrical separation section having steps of increased diameter and equipped with tips adjustable by an angle from 00 to 900 in the horizontal plane, it is possible to obtain fractions of the required quantity and size. By doubling the diameter of the next stage compared to the previous one, it was possible to create a pressure drop and separate the polydisperse material by changing the particle velocity. The ecological advantage of the processed technology is noted, since during the separation of dispersed particles, part of the dust contained in the powdery mixture leaving the unit with the flow of air (gas) is retained in a dry holder, and the rest is in water (absorber)

Due to the development of nanotechnology and changing customer demands for food safety and hygiene, the food packaging industry is growing significantly. In today's worldwide market, active packaging offers a number of advantages over traditional wrapping because of its capacity to absorb or release substances to improve the shelf life of food. Traditional food packaging materials are difficult to recycle and are made from nonrenewable fossil fuels. Development of Biodegradable films using Nano cellulose can be a good replacement for synthetic plastic packaging materials and can be a good solution for this problem. Other than that it has multiple advantages regarding tensile and physical properties, also in reducing health hazards. Tensile and physical characteristics are improved and water vapor permeability is decreased with the addition of cellulose nanoparticles to the biodegradable films/biodegradable composite films. The production of biodegradable materials employing Nano cellulose has been covered in this review study in four different ways, including extracts from agricultural waste, rice husk, various plant extracts, and biopolymer composite material in food packaging. The reason for using Nano cellulose based Biodegradable films in food packaging are also reviewed in this article. The key points for the future research in overcoming the problems related to Nano cellulose, biodegradable films are also predicted in the paper

In the presented research work, zinc and aluminum containing layered double hydroxides on the polyvinyl alcohol matrix (ZnAl LDH/PVA) were prepared by the co-formation technique and characterized by X-ray diffractometer, Brunauer-Emmett-Teller (BET) and Ultraviolet-visible (UV-Vis) spectroscopy. Both low and high pH is determined as optimal pH for Patent Blue V (PBV) adsorption on the ZnAl LDH/PVA nanocomposite and it is explained by the fact that the dye molecule is zwitterionic. Sorption of Patent Blue V food additive (E 131) on the obtained nanocomposite was studied by Temkin, Freundlich, Langmuir, and Dubinin-Radushkevich (D-R) isotherm models. Based on the obtained isotherm curves, the adsorption of PBV more closely matches Temkin model. The regenerated nanocomposite shows higher adsorption because the specific surface area increased from 5m2 g-1 to 8.94 m2 g-1 by BET analysis

Three types of gums of plant origin taken from young trunks of fir, cherry and acacia trees were used in the presented research. The collected plant origin gums were dissolved separately for 24 h with continuous stirring, filtered and redried and grinded into powder and their solutions with concentrations of 250, 500, 1000 and 2000 mg/L were prepared. The viscosities of gum of plant origin in fresh water and in the presence of salt and surfactant, as well as the dependence of these viscosities on the amount of plant origin gum and temperature, were studied. It was determined that it is impossible to achieve a viscosity of 80 mPa×s when the density of cherry gum is lower than 5 g/L. At concentrations of 3.5 g/L and 2.0 g/L, acacia and fir gums give the solution a viscosity of ~80 mPa×s. It has been shown that all three biopolymers retain their physico-chemical properties up to 2400C, and solutions made from gums can be used for compression of oil even in high-temperature wells

Authors:   Institute of Polymer Materials, Ministry of Science and Education of the Republic of Azerbaijan, Aslanova E.T.
Published: March 2023

By polycondensation of triglyceride of saccharin-6-carboxylic acid with some aliphatic diamines, the thermal-stable super-branched polyestersulfoimides – polyglycerides of saccharin-6-carboxylic acid have been obtained. The structures of the synthesized compounds have been confirmed by data of the IR spectroscopy. The yield of the purposeful product was 80–83%. It has been found that the synthesized polyglycerides are well dissolved in polar aprotonic solvents. The thermal stability of the obtained compounds was studied by a method of differential-thermal analysis on derivatograph of system ʺPaulik-Paulik-Erdeyʺ. The derivatographic investigations showed that the synthesized polyglycerides have high thermal stability, decreasing with the growth of length of the aliphatic fragment in their composition. For comparative estimation of the thermal and physical-mechanical indices of the synthesized polyglycerides, the corresponding indices of the industrial polyesterimide Zellamid 1000 have been also given. It has been found that the obtained polyglycerides do not concede to industrial polyesterimides on physical-mechanical indices, but exceed them on thermal stability

One of the smart methods of controlling the increasing demand for raw materials and environmental pollution is the recycling of waste. In this study, optimum conditions were determined for the conversion of wastes that will not be reused in the textile industry into functional activated carbon. For this, raw and Fe, H2SO4, H3PO4 impregnated textile wastes were carbonized at different temperatures for varying times. The molecular structure and crystal lattice of the prepared activated carbons were investigated by FT-IR and XRD analyzes, respectively. SEM and BET analyzes were used to examine the morphology and surface properties of the samples. The existence of C=C, C=O, and C–O–C functional groups was recognized by the vibrations at around 1300-1700 cm-1. A well-crystalline and porous structure was formed as a result of the carbonization of the Fe and H3PO4 pretreated samples, while the process was conducted at a lower temperature due to the catalytic effect. 25–85 mg/g methyl orange (MO) and industrial textile water (ITW) removal capacity were recorded for all samples. Efficient biochars were obtained by carbonization of waste materials while protecting the environment. Such a specific approach could be developed for each waste material for environmental and economic production

Authors: Lopes Rivanaldo Martins
Published: March 2023

O estudo de análise combinatória no ensino médio tem-se apresentado como um dos assuntos mais difíceis de ser ensinado e aprendido por parte dos professores e estudantes. Nesse contexto, o presente trabalho objetiva mapear, em produções escritas, as principais estratégias utilizadas por professores para ensinarem esse componente curricular de matemática, bem como o nível de dificuldade para a assimilação desse conteúdo por parte de estudantes do ensino médio. Para atingir os objetivos propostos neste trabalho, foi realizado um levantamento bibliográfico do assunto nas bases de dados do Scielo e Google Acadêmico, compreendendo uma janela literária de 2013 a 2022. Como descritores, utilizaram-se as palavras análise combinatória no ensino médio, estratégias didáticas de análise combinatória e análise combinatória na contemporaneidade. Após o levantamento dos artigos, estes foram agrupados conforme a pertinência do assunto. De acordo com a análise dos artigos selecionados para a revisão integrada, constatou-se que a utilização de ações que trabalham os conteúdos interdisciplinares possibilita aos estudantes maior aproveitamento dos conteúdos vistos em sala de aula, principalmente as definições e aplicações dos conceitos de análise combinatória na educação básica. Na dinâmica de ensino-aprendizagem de análises combinatórias, têm-se utilizado diversas estratégias de ensino, como o fluxograma, que não deve ser entendido, de maneira alguma, como um método que dará a resposta dos problemas de análise combinatória, e sim como um guia sobre quais questionamentos devem ser feitos, após ter consciência das regras estabelecidas nas situações de contagem, a fim de decidir que recursos deverão ser empregados para realizar as contagens de forma eficaz. Outra forma de se trabalhar análise combinatória tem sido o uso da modelagem matemática. Além da modelagem, a exploração, resolução e proposição de problemas no ensino médio para o aprendizado de análise combinatória têm sido objetos de estudo.
DIAGNOSTICS OF THE SOCIO-ECONOMIC CONSEQUENCES OF ECONOMIC CRIME, IDENTIFYING THE SYMPTOMS OF THE PROBLEM OF ENSURING ECONOMIC SECURITY
Authors:   Zhytomyr Polytechnic State University, Dykyi Anatolii
Published: March 2023

The greatest influence on the level of economic security of the state is exerted by the consequences of economic crime, manifested in the socio-economic sphere. The socio-economic consequences of economic crime are extremely important from the point of view of their elimination and prevention in the future, they are direct indicators of the level of economic security of the state. Thus, economic crime leads to the growth of the shadow sector and, as a result, a lack of budget revenues, which is reflected in the country’s public debt; a high level of economic crime affects the state’s competitiveness, because it determines the state of the economy and affects the effectiveness of the country’s government; lowers the level of the business environment and leads to a low level of infrastructure. Economic consequences lead to social consequences that affect the gap between the incomes of the population and their quality of life. The conducted research made it possible to identify a set of socio-economic consequences of economic crime, including: the formation of a package of debt obligations to external institutions to cover the deficit of own budget funds, which is caused, among other things, by various types of economic crimes, which leads to the emergence of threats in the national system security in general and economic security in particular; a decrease in the level of the country’s competitiveness as an international agent as a result of unsuccessful economic policy and government activity, which favors the emergence and development of destructive processes in the country’s economic security system; the differentiation of society according to the level of income and access to various social benefits, which determines the quality of life of the population, and therefore forms the level of the country's development, which is the basis for the formation of national security in general and economic security in particular.

Розкрито роль та значення фінансового планування діяльності підприємства у забезпеченні його фінансової стабільності. Зазначено, що за допомогою фінансового планування значно зменшується невизначеність ринкового середовища та його негативні наслідки для суб’єкта господарювання. Однак на практиці значення фінансового прогнозування і планування невиправдано занижене через ряд причин (високий рівень невизначеності у ринковому середовищі; нестабільність нормативно-правової бази підприємницької діяльності; недостатній обсяг фінансових ресурсів у підприємств, криза платежів та високі процентні ставки, що обумовлюють фактичну відсутність коштів для здійснення великих інвестиційних проєктів тощо). Виділено такі напрями удосконалення організації фінансового планування діяльності підприємства, як: впровадження бюджетування як інструменту оперативного контролінгу; впровадження фінансового контролінгу; впровадження стратегічного планування на підприємстві; мінімізація ризиків; зменшення дебіторської заборгованості та ін.
MODELING ECONOMIC GROWTH BY INTELLIGENT DATA ANALYSIS
Authors:   National Aviation University, Telnova Hanna , Popov Vadym ,   National Aviation University
Published: March 2023

The article substantiates the expediency of using intelligent data analysis in the study and forecasting of economic growth. Intelligent data analysis is a powerful tool that can help researchers and politicians understanding economic growth more deeply and making reasonable decisions by forming state policy. In addition, intelligent data analysis can be used to determine the potential areas of economic growth and investment opportunities. Attention is focused on using CART (predictive modeling tool, which has proved its high efficiency in understanding the non-obvious relationships between several variable statistical importance) and associative rules (intelligent data analysis, which can work with big data arrays and generate clear and effective conclusions, supported by statistical significance indicators). It is concluded that the methods of intelligent data analysis, such as CART and associative rules, are crucial for understanding the complex patterns that exist in large arrays of economic data. The advantages of these methods make them appropriate and effective tools for modeling and understanding of levers and tools of economic growth. Based on the analysis of data for 119 countries of the world for 2021 (the period of post-pandemic recovery), it was established that in order to promote economic growth, countries with low levels of export and import need to focus on the development of national industry. In addition, developing an economic policy aimed at promoting the recovery of the economy, it is necessary to increase the democratic status of the country. In general, countries that are less dependent on exports and imports tend to have more stable and self-sufficient economies. This can be explained by a number of factors, such as a strong domestic market, the development of national industry and less vulnerability to global economic shocks. In addition, a low level of imports may indicate that a country is able to produce and consume a significant portion of its own goods, which may contribute to further economic growth and development. It is important to note that these relationships are based on highlevel statistical correlations.

Published: March 2023

The conservation status of amphibian species was studied in the Region of Murcia, taking into consideration 10 variables concerning their biology and distribution. The results obtained show that the amphibian species exposed to the highest risk of extinction in the study area are those with long larval development and a restricted distribution range. According to this species classification, an index is proposed for assessing areas whose conservation is of the highest priority. In the Region of Murcia, most of these areas are located in the main mountain systems, primarily confined to the northwest. Regional Parks and proposed priority conservation areas overlap by only about 12%. The current isolation of these areas makes it necessary to undertake habitat restoration programmes to ensure their interconnection.

Parataxonomy: a test case using beetles
Authors:   Nova Scotia Museum of Natural History, Halifax, Canada, Majka C. , Bondrup-Nielsen S. ,   Acadia Univ., Wolfville, Canada
Published: March 2023

The present study examines the utility of parataxonomic sorting (groupings of similar individuals, categorized by non-experts, relying on features of external morphology) using data from a study of beetle communities in four forest habitats in Nova Scotia, Canada. Alpha diversity and the Shannon-Weaver, Simpson, Berger-Parker, and Brillouin indices of diversity, derived from both taxonomic species and parataxonomic units, are compared and yield identical habitat rankings. Beta diversity rankings derived from both data sets do not differ although they produce slightly different rankings. The Elateridae, Curculionidae, Cantharidae, and Staphylinidae had particularly large numbers of “lumping” and “splitting” errors. Although the overall gross sorting error was only 14%, individual families of beetles had errors between 0% and 200% with an average error of 38%. The limitations of the parataxonomic approach are discussed; both in regard to the practical application of the concept, as well its theoretical basis. We note the spillover of this discourse to the subject of what constitutes a species and observe that this discussion has been misplaced due to the unfortunate confusion of the two usages of the term “morphospecies”.
Temporal variability of spawning site selection in the frog Rana dalmatina: consequences for habitat management

Published: March 2023

We evaluated whether R. dalmatina females laid their eggs randomly within a pond or preferred particular microhabitats. The same measures were performed in the same area in two consecutive years to determine whether the pattern remained constant over time. In 2003, we observed a significant selection for areas with more submerged deadwood and vegetation, presence of emergent ground and low water depth. However, these results were not confirmed in the subsequent year when none of the microhabitat features measured had a significant effect. Although microhabitat features can strongly influence tadpoles, the temporal variability of habitat at this spatial scale suggests that habitat management could be more effective if focused on a a wider spatial scale.

Objective: To determine the reason for the low response to the exclusive use of prostaglandin in synchronization programs in cows under tropical grazing compared with the use of progesterone (CIDR).
Design/Methodology: Thirty-five cows with CL were randomly distributed in two groups. The first group (GPG; n=23) was synchronized using two doses of PGF2α (25 mg of Dinoprost®) with a 12-day interval. The second group (GCIDR; n=12) was synchronized with an intravaginal device (1.9 g of progesterone, 2 mg of estradiol benzoate, and 50 mg of progesterone); a PGF2α (pm) dose was applied on day 7, before removing the CIDR (am) on day 8. CL regression, luteolytic failure, progesterone concentration, and CL size were determined. Data was subjected to a normality test, followed by the Mann-Whitney U test or independent Student's t-test and chi-square test.
Results: Only 82.6 % (19 out of 23) of the GPG cows that received the second dose of prostaglandins have a functional CL (<1 ng mL-1 of progesterone). The CL recorded a regression only in 43.5% of the cows in GPG vs. 91.7% in GCIDR (P=0.0001). In addition, GPG cows showed a luteolytic failure of 39.1% and an asynchrony of 17.4%.
Conclusions: The low effectiveness of prostaglandin on the synchrony and regression of the CL (luteolytic failure) in cows fed under tropical grazing can be attributed to the low efficiency of the synchronization programs.

Design/methodology/approach: Sowing ratios of 4:2 and 6:2 were studied to observe their effect on the genotypes, as well as their quality and response in seed production; this was done by evaluating the following variables: days to male and female flowering, plant and ear height, percentage of ear and seed in cobs, commercial seed yield, thousand seed weight, number of seeds per kilogram, standard germination and hectoliter weight of the seed. An analysis of variance was carried out using a completely randomized design with factorial arrangement and four replications, the experimental unit being furrows of 20 linear meters.
Results: Significant differences were detected in the hybrids with respect to the variables and sowing ratios, which specifically influences the weight, size and number of seeds; the hybrid H-386A had the best response to the environment and ratios, exceeding the rest of the hybrids evaluated by 72.92 %.
Limitations on study/implications: The interaction of genotype and environment are factors that limit seed production; however, performing evaluations in different environments allows finding stable hybrids with high yields.
Findings/conclusions: The generation of knowledge allows us to make decisions regarding crop establishment and quality in seed production lots, being a recommended environment in CIRPAC’s area of influence

Objective: To evaluate some reproductive aspects of D. latifrons and the nutritional quality of its eggs.
Design/methods/approach: Eighty-two fish were randomly collected (August 2021), and their sex, length, weight, somatic indices, Fulton condition index (K), proximate composition, and amino acid and lipid composition (fatty acids) of the gonads were determined.
Results: Of the total specimens collected, 62% were females; length and weight values were higher in males, but their gonadosomatic index (GSI) was lower than in females. Somatic indices did not show differences between different weight ranges. In the roe of D. latifrons, the average proximate composition was 24.3% protein and 8.5% lipids. The most abundant essential amino acids were leucine and lysine. Linoleic acid (C18:2n6) was the fatty acid with the highest concentration.
Limitations/implications: It is necessary to complement the analysis of the amino acid and fatty acid profile of the roe in wild organisms to relate the changes caused by balanced feed.
Findings/conclusions: This study shows that the D. latifrons roe is a good source of amino acids and PUFA.
Keywords: proximate composition, fatty acids, essential amino acids

Objective: To examine how priming radish (Raphanus sativus L.) sprouts with zinc oxide nanoparticles (NPs-ZnO) affects their germination, photosynthetic pigments, phenolic compounds, and zinc content.
Design/methodology/approach: We evaluated five NPs-ZnO treatments and a control sample with four replications under a completely randomized design.
Results: Sprouts treated with NPs-ZnO showed increased germination variables, photosynthetic pigments, phenolic compounds, and zinc content as compared to untreated radish sprouts.
Study limitations/implications: It is hard to establish a response model for the effects of NPs since their shape, size, surface charge, chemical composition, and concentration may have a differentiated impact on seed germination.
Findings/conclusions: Using NPs-ZnO could be an effective way to enrich crops, since the passage of Zn through plant tissues will cause an accumulation of this micronutrient.

The current study was to estimation the post-harvest loss of avocado at the producer level using cross-sectional data obtained from 385 proportionately sampled respondents from Wolaita and Kembata Tembaro Zones, the SNNPR of Ethiopia. Descriptive and multiple regression analysis were used to estimate the amount and determinant of post harvest loss. The average post-harvest loss of avocado at the producer level was estimated at 24.1 per cent, of which 5.7 per cent was due to poor harvesting practices and 4.9 per cent to poor storage practices. Sex, education, income, training, contact with extension agents, distance from the nearest road, and off-farm income were found to be negative determinants, whereas storage accessibility and avocado harvest techniques were found to be positive determinants of post-harvest loss of avocado fruits. Post-harvest losses contribute significantly to food insecurity and create a problem for the income source of individuals and the economy of the country.

This study analyzed the attitudes of university students towards digital citizenship to improve practices when using technologies. The methodological design was mixed with a qualitative phenomenological approach and the quantitative part was correlational-causal with a non-experimental cross-sectional design. 84 students participated, of which 45 were studying engineering and 39 undergraduates. To obtain data, a semi-structured survey was applied individually to 72 participants, a focus group of three key informants and nine in an interview. The findings show that the process of appropriation of digital citizenship in university students still has a long way to go, given the limited acquisition of behaviors inherent to the proper exercise of digital citizenship. In this sense, the results are expressed in two aspects; on the one hand, the positive attitude where technology is expressed as an important part of society and its development, on the other hand, there is the negative attitude that perceives technology as a mere expendable tool. Finally, it is concluded that students must still improve the use of technologies since this use can negatively affect their training process.

Published: March 2023

Digital knowledge constitutes knowledge, skills and attitudes related to the use of Information and Communication Technologies (ICT) in the educational field. The training of normalist teachers requires, as a graduation profile, to strengthen the development of digital knowledge that allows them to enrich the design, development and implementation of didactic situations and sequences with the use of ICT, not only from an instrumental level, but also from a didactic perspective. This research presents the results of a quantitative, non-experimental, descriptive study, whose objective was to diagnose the appropriation of digital knowledge in the formation of Mexican normalist students. The sample consisted of 505 Mexican normal students from the states of Chihuahua, Hidalgo and Tamaulipas, who were administered a questionnaire with a Likert-type scale with 36 items distributed in 7 dimensions. Among the main findings, digital knowledge was identified with a higher score for the use of messaging services, as well as the management of different types of sizes and fonts; the lowest scores were recorded in data analysis with specialized software and the development of blogs to communicate information.

Published: March 2023

BACKGROUND. Post-COVID syndrome is a set of conditions that occur in patients after a coronavirus infection. To date, there remains great interest in identifying the relationships between the influence of concomitant diseases on the course of SARS-CoV-2 infection and the selection of a justified treatment regimen from the point of view of the pathogenesis of the formation of long-term consequences of the disease.

OBJECTIVE. To investigate the role of comorbidity in the development of Long-COVID, to study and analyze the results of treatment with a combination of Xavron, Tivorel and Xylate in patients with asthenic manifestations of Long-COVID.

MATERIALS AND METHODS. A clinical and neurological examination of 50 patients aged 47 to 76 years with a diagnosis of chronic cerebral ischemia and an asthenic syndrome that persisted for more than 3 months after a confirmed SARS-CoV-2 infection was carried out. All patients were treated according to a clinical protocol approved by the MOH of Ukraine. In addition to the main treatment, 20 patients received a 10-day course of infusions of a combination of the drugs Xavron in a dose of 30 mg No. 10, Tivorel 100.0 No. 5 and Xylate 200.0 No. 5 every other day. Efficacy was assessed before treatment, on the 5th and 10th day of treatment using the MMSE, DASS-21, FAS and MOND scales.

RESULTS AND DISCUSSION. A stable positive relationship was found between the number of CIRS-G comorbidity scores and the MOND score. A positive correlation coefficient between comorbidity and asthenic syndrome, assessed on the FAS scale, was also expressed – 0.699 (p<0.001). A somewhat weaker negative relationship was found between anxiety and the number of points on the CIRS-G scale – -0.474 (p=0.035). Assessment of depression and stress on the DASS-21 scale did not show a reliably significant correlation effect. After treatment, the severity of neurological symptoms, assessed by the MOND scale, decreased from 5.6±1.6 to 2.8±1 (p<0.01). Depression and anxiety scores on the DASS-21 scale decreased moderately from 4.9±3.6 to 2.8±1.5 (p<0.01) and from 6.3±2.3 to 4.3±1.5 (p<0.01), respectively. A more significant regression was observed on the stress scale – from 10.3±3.1 to 7.5±1.9 (p<0.01). The difference in the severity of fatigue from 28.8±4.1 to 20±1.2 was especially noticeable (p<0.01). CONCLUSIONS. Asthenic syndrome, which is prevalent in the Long-COVID, directly depends on the background of chronic diseases. The combination of Xavron, Tivorel and Xylate is pathogenetically justified and safe in the treatment of patients with Long-COVID. The use of this combination leads to a reduction of asthenic syndrome, which, in turn, has a positive effect on the reduction of cognitive manifestations of Long-COVID in the form of “brain fog”.

The high egg production and fast growth of the Japanese quail attracts a lot of attention to quail farming. This is ensured by the reproductive system of quails, which allows you to purposefully influence their productivity. However, the intensive feeding and rearing systems recently used in commercial quail farming are detrimental to the health of quails. The use of medicinal plants as effective natural growth stimulants can solve this problem, since this direction has found wide application in animal husbandry. This study is intended to determine the effect of an aqueous extract of chamomile on the reproductive organs of the Estonian Japanese quail breed (testes in males and ovaries in females). 40 Japanese quails (experiment-20 and control-20) took part in the experiment, the experimental group from the age of two weeks was fed this chamomile extract for four weeks (chamomile extract 3 ml/l together with drinking water). The results of the study showed that in the chamomile extract the total content of phenols is 108.92 µg/ml, the total content of flavonoids is 66.41 units. mol/ml, and the total antioxidant capacity is 1.77 ng/ml. Chamomile extract increased body weight, absolute and relative weight of reproductive organs, linear dimensions and shape index. Quail testes react especially effectively to chamomile extract, as for quail ovaries, no noticeable differences in their morphology were found.
