The aim of this research was to assess whether the administration of melatonin during pregnancy and lactation can mitigate alcohol-induced liver and kidney damage in the offspring. Three groups were formed with the offspring of 30 albino Wistar rats from the UFRPE bioterium: control group – Offspring of rats that did not consume alcohol; alcohol group – Offspring of rats that consumed alcohol; alcohol+mel group – Offspring of rats that consumed alcohol and received melatonin. The female rats received 3 g/Kg of alcohol and 0.8 mg/Kg of melatonin during the gestational and lactation period. The rat pups were euthanized at 30 days of age. The collected organs underwent histological procedures for morphometric, histopathological and statistical analyses. In the liver of the alcohol group, congestion in the portal and centrolobular veins, steatosis, and alterations in the sizes of hepatic parenchyma were observed, which were not present in the alcohol+mel and control groups. In the alcohol group, the kidneys also showed congestion in the cortical area, without the subcapsular space and with altered glomerulus size, on the other hand, the group treated with melatonin did not present alterations in these organs. The statistical analyses of the weights and lengths of the alcohol+mel group also did not reveal any significant alterations when compared to the group exposed only to alcohol. Thus, melatonin acted positively, interfering and mitigating the harmful effects that ethanol had on the liver, kidneys, weight and length of offspring whose mothers were subjected to chronic alcohol consumption.

Published: August 2023

The article examines the prerequisites for the formation of deposit deposits of the population in banking institutions. The structure of deposit deposits of individuals for 2016-2020 is disclosed. It has been proven that the largest resource for forming an acceptable amount of financial investments is the resources of individuals, that is, household savings. Savings of individuals are formed at the expense of incomes and expenses received by households, as well as financial proposals for investments offered by the banking system or financial institutions. The size and dynamics of changes in the income of the population of Ukraine for 2016-2020 have been analyzed. It was established that the largest increase in aggregate resources - income of citizens during the researched period (2016-2020 years) occurred at the expense of such resources as wages. At the same time, if we compare the incomes of the population in foreign countries, the share of cash income from wages is consistently high and is on average 65-70% of all incomes. The structure of expenditures of the population of Ukraine for 2016-2020 per family was analyzed. It has been established that more than 50% of citizens' expenses are expenses for food products. Having analyzed the dynamics of incomes and expenses of Ukrainian households during 2016-2020, we note that those funds that remained unused can be directed to the formation of savings of the population with further investment.

Objective: To evaluate the quality of a Cambisol at different times of agricultural use in the Los Ríos region (RR), Tabasco, Mexico.
Design/Methodology/Approach: Four agricultural uses were selected on a Cambisol (CM): rainfed crop (RC), annual crop (AC), pasture (Pa), and secondary vegetation (SV). These were established at three different times (1984, 2000, and 2019) with four replications. Soil was collected using an auger at a depth of 0-30 cm. The physicochemical properties of the soil—such as texture (T), bulk density (BD), aggregate stability (AS), pH, electrical conductivity (EC), organic matter (OM), total nitrogen (N), phosphorus (P), and potassium (K)—were determined. A factorial analysis of variance was performed (significance level p=0.05). Variables that showed a statistically significant effect were subjected to Tukey's multiple comparison test (significance level p=0.05).
Results: Statistically significant differences (p≤0.05) were obtained for OM, P, K, and BD contents. The high OM content present in CM with SV in all years shows a better soil quality compared to CM with RC and AC. The high BD recorded in CM with Pa since 1984 shows soil quality degradation by compaction resulting from grazing due to extensive livestock farming.
Study limitations/Implications: Sustainable management practices are required to recover degraded CM.
Findings/Conclusions: OM and BD contents were the best quality indicators for the CM affected by the change in agricultural use and time of use in RR, Tabasco.

ABSTRACT
History is always dynamic in nature just like any other disciplines. Although it is conservatively portrayed that "history is for the winner," but it is actually a reflection of the  life of contemporary society. The field of history evolved into a discipline that analyzes human nature and society on its own track of knowledge. This field has been significantly affected by the development of science that dominates the disciplines of humanities and social science. The 20th century has once again seeing a transformation within the field of history, when it was integrated into other areas of social sciences and transformed from pure history to the new approach known as ‘Applied History’. This paper aims to discuss the development of history disciplines that led to the emergence of the ‘Applied History’ in Malaysia. Overall, the emergence of ‘Applied History’ within the historical discipline in Malaysia is in line with the developments which revolving around the world, particularly in Europe and United States of America. The transformation of the new approach in the domain of history is seen as a two-pronged advantages of the fundamental role in the nation building development while ensuring the survival of history disciplines remain relevant just like other disciplines in the mainstream of the national education system.

Published: August 2023

Owning a house is among the significant aspects of a productive lifestyle. However, the persistent rise in house prices has affected homeownership for low-income young adults. Due to the poor financial literacy among employed young adults in Malaysia, it is more difficult for them to own a home due to financial constraints. Therefore, this study intends to investigate the factors contributing to financial literacy and the potential risk associated with its absence among working young adults. The methodologies used in this study were the factor analysis approach and decision tree analysis. Note that this study investigates financial literacy among young adults. A questionnaire was utilized for gathering the data, and a convenient sampling technique was adopted for data collection. According to the findings, four variables influence financial literacy among working youths: financial knowledge, financial behavior, financial education, and financial attitude. Consequently, the factors listed in exploratory data analysis in these four variables have been summarized to examine the perceived risk of financial literacy among adolescents in terms of purchasing a home. Finally, this study contributes as a guideline for policymakers in offering structured awareness programmes to improve financial literacy as well as homeownership knowledge among working youths for their future financial resilience.
Water Use and Water Saving Strategies in Dialysis, Room for Improvement?
Authors:   Inuvai, Fresenius Medical Care, Germany, Lucena Rui
Published: August 2023

Dialysis treatment consumes a significant amount of water and energy, which entails an important waste management effort. Those variables play a relevant role on the total cost of a dialysis session. Strict dialysis water and ultrapure dialysis fluids standards were established as a pre-requisite for online convective therapies (e.g., hemodiafiltration), improving biocompatibility of the dialysis system, reducing inflammation profile of the dialysis patients, enhancing the responsiveness to erythropoiesis-stimulating agents and thus having the potential for improved survival. The main purification step of a dialysis water treatment system is the reverse osmosis. Fouling of reverse osmosis membranes remains a major issue and all effort should be made to reduce it, to ensure a constant output. Naturally occurring waterborne filamentous fungi, yeasts, bacteria and fragments may contaminate dialysis water and, consequently, dialysis fluids. To maintain the dialysis water treatment system under proper conditions and fulfilling the dialysis fluids quality standards there is a need of a significant effort, namely in terms of cleaning and disinfection procedures of the reverse osmosis, distribution systems and dialysis machines. Improving the reverse osmosis inlet water quality profile by installing an Ultrafiltration system as a pre-treatment, could have an impact in terms of dialysis water quality outcomes, water and energy consumption, and disinfection frequency. The water treatment system efficiency is strongly influenced by the system design and reverse osmosis setup. System design (i.e., not over dimensioned) with a clear focus on increasing efficiency is mandatory if one wants to decrease the carbon footprint. Dialysis prescription (namely dialysis fluid flow rates) plays an important role in the dialysis fluid consumption and consequently the water consumption. A more environmentally friendly dialysis can be influenced by optimization of the current technology and development of innovative technology, and by the adoption of a conscious and coherent behavior of all persons involved in the daily routine of a dialysis unit.

Published: August 2023

Strengthening character in the development of global culture is needed to deal with the moral crisis that occurs in the younger generation, which is mainly eroded by the life of hedonism. Global culture has a lot of influence on changes to local culture, which is in line with moral decadence. The purpose of this paper is to tie the two dimensions that have been running for a long time in Malay society; on the one hand, they are very important and cannot be separated. The Tunjuk Ajar Malay culture and the Sirah Nabawiyah become a means of integration and implementation of characters that can organise a harmonious life. This research uses a qualitative literature method with data sources of observation, literature review and content analysis of the stanzas of Tunjuk Ajar Malay culture and lessons contained in Sirah Nabawiyah with descriptive character implementation in the community. The integration of Tunjuk Ajar Malay culture and Sirah Nabawiyah in the implementation of character is an acculturation of religious and cultural norms that reflect religiosity. In the practice of behaviour related to character, the realisation of an integration arranges the character of the younger generation in the development of global culture.

Published: August 2023

The present study scrutinizes aggression as an influential social phenomenon in five American animation movies. Animation movies are often regarded as the finest form of entertainment, and children can learn a lot from them. However, they contain a huge number of aggressive scenes. Aggression and its social impacts have been examined from different perspectives. However, investigating aggression in American animation movies has not been conducted particularly from a pragmatic viewpoint. Thus, the present study attempts to bridge this gap by identifying types and causes of aggression pragmatically. The major goal of the study is to determine the types and causes of aggression performed by aggressors by looking at how speech acts are utilized to express each type and cause of aggression in the data that is being examined. To achieve the aim of the study, Searle’s (1969) classification of speech acts is adopted. The main conclusion of the study is that expressive speech acts are used in all types of aggression, with the highest frequency and percentages. Moreover, expressive speech acts are most frequently linked with the failure factor and the social learning factor as causes of aggression.

Analysis and Design of Voltage-controller Based on Single-state Feedback Active Damping for Grid-forming Converters
Authors: Abdoune Fateh , Abadlia Issam , Beddar Antar , Hassaine Linda , Bengourina Mohamed Reda
Published: August 2023

This paper investigates the analysis and design of digital single-loop voltage-controller for grid-forming voltage source converters with LC-filters. Inspired by the structure diagram of the passive damping method, the virtual resistance concept based on only capacitor voltage feedback is used to realize active damping without the need of any current sensor, reducing thus the system costs. It is revealed from the controller closed-loop analysis that the insertion of an integrator in series with a proportional and resonant controller can significantly improve stability margin and dynamic performance of the system, then only the proportional controller need to be determined for system stability and the resonant controller is merely used for zero steady-state tracking error, which facilitates the controller parameter tuning. A systematic design based on the root contours in the discrete z-domain is proposed to optimize the parameters of the controller. The largest distance between the poles of the closed-loop system and the unit circle is achieved, which indicates the fastest dynamic performance under desired stability margins. Meanwhile, a simple differentiator constructed by backward-Euler plus lead-compensator is used to replace the noise-sensitive derivative term. In order to evaluate the proposed control approach performance, the system is tested in laboratory setup under different load conditions. The obtained results verify the effectiveness of the proposed design method and validate the analysis.

Aluminosilicatehalloysite nanotubes as a tool of modern nanocomposites for food safety
Authors: Haiuk N. , Tsekhmistrenko O. , Seleznyova A.
Published: August 2023

Nanoscale natural clay minerals, which include Si, O, Al, and Mg, are a class of environmentally safe inorganic materials with unique structures and diverse morphologies, including nanorods, nanofibers, and nanotubes. Aluminosilicatehallusite nanotubes (HNTs) are relatively new objects of research in materials science, they have a number of environmental and economic advantages compared to carbon nanotubes (CNTs), as well as fullerene and graphene. Natural halloysites are an order of magnitude cheaper than their synthetic counterparts. The location of halloysite is quite common, for example, in the KryvyiRih region and other places in other countries. Due to their high environmental friendliness and bioavailability, HNTs can be used in medicine, including as drug carriers with controlled release. HNTs can also exhibit (photo) catalytic properties, have high adsorption properties in relation to heavy metals Cu(II), Pb(II), Cd(II), Zn(II), Cr(IV) and Co(II) and solutions, containing dyes, pesticides and some other organic pollutants, as well as toxic gases (ammonia, hydrogen sulfide). HNTs in combination with other metals, such as Mn, Ti, acquire various practical applications. HNTs were introduced to ensure better functional photo(electro)catalytic properties of composites that can be a substrate, especially in the case of nanotube oxide decoration. For example, titanium, a white pigment, non-toxic, is included in the list of food additives and is designated as E171. Contained in food products: candies, cookies, cakes, chicken fillet, crab sticks, chewing gum, chocolate products. Although the addition of titanium dioxide in food products is permitted by many official documents, there is insufficient data in the scientific literature regarding the potential danger of titanium dioxide to the human body. Increased interest in TiO 2 is due to its high photocatalytic activity, which allows to realize processes of destruction of organic compounds, including ecotoxicants, into safe products. HNTs, or materials based on them, have found many useful applications in the treatment of drinking water and industrial wastewater. The structural features of HNTs make it possible to obtain new composite materials based on them, such as, for example, imohalite nanotubes (INTs) of a wide functional purpose and to determine the physicochemical patterns of their formation. Therefore, the relevance of the work lies in the combination of hallusite nanotubes and titanium dioxide as composite materials using electrosynthesis, and the analysis of the influence of the phase composition, photocatalytic activity of the composite material on the safety of its practical use, including in the food industry.

Authors: Khmelnychyi L. , Samokhina E. , Khmelnychyi S. , Karpenko B.
Published: August 2023

The researches were conducted in the aspect of studying the problem of dairy cows lifetime depending on the linear traits assessment of the conformation type. By the linear classification method were estimated firstborn cows of the Ukrainian Black-and-White dairy (UBWD) and Holstein (H) breeds. Descriptive traits of the conformation that characterize the overall body structure were studied: chest width, body depth, angularity, body condition, rear width and position. According to the research results, the relative variability of the descriptive type traits assessment with cow's lifetime was determined. The relative variability of chest width and cow's lifetime was curvilinear. Cows for chest width assessment of 4–7 score had a higher lifespan with a variability of 2704–2844 (UBWD) and 2688–2789 (H) days. The highest lifetime was in animals with an assessment for body depth development of 6-9 score with an unreliable predominance of Ukrainian Black-and-White dairy breed cows, with the highest grades of both breeds 2824 (UBWD) and 2802 (H) days with an assessment of 9 score. Animals with an optimal angularity estimation of 5 score differed, lived the longest – 2842 (UBWD) and 2828 (H) days, while with increasing and decreasing score for this trait, the number of lifetime days of cows declined. According to the rump width assessment, lifespan was highest in cows with a 9 score – 2766 days (UBWD) and 2832 days (H). Cows of UBWD with the highest assessment for this body part development of 9 score were used on 592 (P <0.001), and Holstein on 708 (P <0.001) days longer compared to animals with 1 score. The maximum lifetime of animals with an average assessment for body condition of 5 score was 2842 (UBWD) and 2774 (H) days. Cows with body condition score below average lived and were used in the herd much longer than with a higher one. The degree of relationship variability between the assessment of these traits and the lifetime of animals depended on the specific body part.

Biological value of green amaranth mass and its use in composition of combined silos for young pigs
Authors: Kryvyi M. , Horchanok A. , Kuzmenko O. , Vasiliev R. , Dikhtyar O.
Published: August 2023

Every year in Ukraine and around the world, the demand for grain products increases, which leads to increased competition between humans and animals. The increase in global grain prices makes livestock production more expensive and less profitable. In turn, the change in natural climatic conditions, the shortage of energy resources prompts scientists to search for fodder crops that would be high-yielding, cheap, biologically complete, ecologically clean, able to effectively influence the productivity of animals and replace part of grain fodder. Today, the climatic conditions of the Polissia region, selection and advanced technologies ensure the growth of the cultivation of rare fodder crops. In addition, there is growing interest in introduced plants and the introduction process itself. These are high-yielding plants with a high content of biologically complete protein, capable of forming powerful biomass in a short growing season and being resistant to adverse environmental factors. Studying the results of research on the use of nontraditional crops, which include the amaranth family (Amaranthus L), in our opinion, the issue of finding scientifically based types of pig feeding using cheap and highly nutritious juicy fodder is of great importance. In order to realize this goal, the following tasks were set: to investigate the phenological parameters, yield and chemical composition of the green mass of amaranth according to the phases of growth and development; develop silage recipes and determine the optimal amount of amaranth green mass in the composition of combined silages for fattening young pigs. When developing recipes for combined silages, we followed the following requirements: combined silage should have a high energy value of about 4 MJ in one kilogram of feed; the content of digestible protein per feed unit is 80-100 g and the optimal amount of organic acids. It was established that the maximum yield of amaranth green mass (245.5 t/ha) and the yield of dry matter (62.5 t/ha) was obtained in the phase of wax maturity. It is advisable to include 20-26% of the green mass of amaranth in the composition of combined silos in the conditions of the Polissia of Ukraine and feed it to pigs for fattening from 55% to 75% in terms of total nutrition.

Authors: Bezruchko K. A , Prykchodchenko V. F , Prykchodchenko O. V , Hladka M. O
Published: August 2023

Purpose. To predict zones of increased water inflows based on geological exploration and mining-geological data in the real conditions of an operating coal mine using the method of predictive evaluation of prospects of local structures for the presence of gas accumulations. Methodology. The research was carried out by constructing a map of local structures using trend analysis. The synclinal fold is allocated in the plan and its main parameters – amplitude and width – are determined. Based on these parameters of the structure, the authors performed calculations of relative linear deformations and relative volume deformation of the studied fold. Findings. According to the deviation of the hyposometry of layer (“Samarska” mine) from the approximating surface, a local synclinal structure is allocated on the map. Based on calculated data on the volumetric deformation of rocks (siltstones and sandstones) and average values of open porosity, fracture porosity and absolute permeability were calculated. The obtained data indicate the formation of a fractured zone with improved filtration and capacity properties of rocks within the studied area. According to the actual mining and geological data, within the defined area, there are increased water inflows into the mine workings, which further confirms the results of the prediction. Originality. For the first time, the algorithm of predictive evaluation of the prospects of local anticlinal structures for the presence of gas accumulations was used to predict areas of increased water inflows. Practical values. In the real conditions of an operating mine, in the area of mining operations, the method for predicting zones of increased water inflows was tested according to a predictive evaluation of the prospects of local folds for the presence of gas accumulations.
Tectonics and gravity field structure of Central Kazakhstan
Authors: Abetov A. E , Uzbekov A. N
Published: August 2023

Purpose. Identification of the nature of the manifestation of tectonic elements of different ages in Central Kazakhstan in gravitational fields based on the results of the calculation of regional, intra-crustal and local transformants. Methodology. Synthesis and analysis of the data on integrated interpretation and modeling of gravitational, geomagnetic, geothermal fields, the latest movements of the Earth’s crust and parameters of the seismic regime, tectonics and stratigraphy of rocks. Findings. Regional, intra-crustal and local heterogeneities in the lithosphere manifest themselves differently in blocks of Precambrian rocks, Early and Late Caledonides, Early and Late Hercynides. They may be associated with the processes of Paleozoic intracontinental rifting, with the rise of mantle matter and its emplacement into the Earth’s crust, followed by the manifestation of Late Paleozoic orogenesis, doubling of the thickness of the Earth’s crust, outpourings of magmatic formations. Originality. It is established that large gravitational minima are distinguished in areas with Hercynian folding, characterized by abnormally high amplitudes in the movement of the Earth’s crust. In the regions of the Caledonian folding, the values of gravity field anomalies of intermediate intensity and increased amplitudes of the latest movements of the Earth’s crust are manifested. Areas with Pre-Paleozoic folding have relative maxima of gravitational anomalies and minimum values of the latest movements of the Earth’s crust. Earthquake sources are concentrated in the consolidated crust at the junction of areas with different ages of basement consolidation, in gradient zones of geothermal, geomagnetic and gravitational anomalies. According to the variations of the intra-crustal transformant, it was found that a wide range of changes in the values of the gravitational field corresponds to areas with minimal temperature values, whereas in areas with increased temperature values, the range of changes in the values of gravity anomalies is reduced. The distribution of the local transformant of the gravitational field indicates the existence of highly variable anomalies, which reflects the high-frequency gravitational effect of near-surface objects of the Earth’s crust. Practical value. The distribution of inhomogeneities in the lithosphere with various density, geomagnetic and geothermal anomalies of geophysical fields, the nature of the seismic regime and the latest movements of the Earth’s crust predetermined the formation of geostructures with different types of mineralization, each of which is recommended to be searched and explored by a specific rational set of geophysical methods.

Purpose. To combine the stereophotogrammetric method for processing fracture surface images at the micro level with the results of a series of mechanical and metal fractographic studies with precision methods for scanning electron microscopy (SEM) and energy dispersive analysis (EDX) in order to determine the peculiarities and general laws of the fracture process of Al-Cu-Mg test samples. Methodology. In this work, the mechanical properties of Al-Cu-Mg samples after mild (recrystallization) annealing and subsequent natural aging and a sample without heat treatment were experimentally determined. At the next stage, SEM-stereomicrofractographic research on fractures and their three-dimensional reconstruction from the obtained stereo images were performed. EDX studies have been performed on various parts of the samples to determine the distribution of mass percentages of elements in the study areas. A comprehensive methodology for experimental studies of Al-Cu-Mg alloys was used in this work to obtain qualitative and quantitative information on the microstructure of fractures, which consisted of the following steps: determination of the mechanical properties of samples by traditional methods of macro- and microanalysis; study on stereopairs of the microstructure of fractures by the stereophotogrammetric method; identification of the chemical composition and structure of matrix precipitation particles by energy dispersive X-ray spectroscopy (EDX analysis). Findings. Our experiments have shown that with an increase in the time of natural aging, the hardness increases slowly and reaches a maximum hardness of 127 Hv30 after 97 hours, which does not decrease subsequently. After natural hardening, the average fracture strength increases to Rm 440.3 with a relative elongation of 21.8 %. Mechanical tests have shown that the tensile strength increases with the hardness value and, in contrast, the toughness decreases. The energy required to fracture the sample is 16 J, followed by transcrystalline cellular fracture. The precipitates have a diameter of approximately 2.5–3 microns. Originality. Comparing the results of mechanical and metallographic studies, it can be argued that the desired properties of Al-Cu-Mg samples appear after dispersion hardening, which confirms the optimal hardening conditions. The results of the photogrammetric evaluation of samples in the micro range demonstrate the flexibility and accuracy potential of photogrammetric measurement methods and their subsequent processing, interpretation, and integration with EDX analysis to select optimal study sites. Practical value. An integrated approach to the analysis of materials using the SEM stereomicrophotogrammetric method, mechanical and metallographic studies, and EDX analysis was tested in this work.

Purpose. Study on the process of combining several methods for determining the quality indices of human-machine interaction, containing various configurations for determining the weight coefficients in an ensemble. Methodology. The process of diagnosing the quality of the interaction of a human-machine system with four elements of subsystems is studied using the example of the system “Operator–Machining Center – Control Program – Safe Environment”. The main hypothesis of the study is the combination of several methods for determining the quality indices of human-machine interaction, containing different configurations for determining the weight coefficients in the ensemble. A combined method for diagnosing the quality of interaction between human-machine systems based on ensemble models, which include non-ensemble ones, has been proposed. The ensemble index has been determined by averaging the non-ensemble indices. The defined ensemble indices and element scores of the four subsystems are used as input scores to a multiple regression model to generate prediction. Findings. Four combinations of ensemble indices have been developed and implemented in software, which are characterized by a minimum value of the standard deviation compared to the existing ones. According to the results of experimental verification, the proposed models demonstrate the value of the standard deviation of 0.1404; 0.1401; 0.1411; 0.1397, and the existing ones are 0.1532; 0.1535; 0.1532; 0.1532. Originality. The combined ensemble method for diagnosing the quality of interaction between elements of subsystems takes into account linear models with non-linear variables and different ways of determining weight coefficients. Practical value. The scenario for the practical use of the results obtained is a possible option for optimizing production, where, depending on the final result, specialists can adjust the value of a particular subsystem to achieve the desired result.

O presente estudo tem como objetivo a análise do fenômeno da exportação de resíduos, aqui denominado como tráfico internacional de resíduos, a fim de enquadrá-lo como delito transnacional, já que seus efeitos, a toda evidência, transpassam as fronteiras dos Estados, causando malefícios diretos e/ou indiretos a toda coletividade. A fim de atender ao objetivo proposto, essa apreciação seguiu a seguinte ordem: apresenta-se o tratamento jurídico nacional e internacional acerca dos resíduos; faz-se uma análise acerca da sustentabilidade frente à exportação destes resíduos para, ao final, caracterizar a exportação de resíduos como a prática de ilícito transnacional. Em sede de considerações finais, confirma-se a hipótese lançada, evidenciando que a remessa de resíduos para países que ficarão responsáveis pelo seu tratamento e processamento, de fato, configura-se como delito transnacional, pois afeta de forma evidente a sustentabilidade e compromete a manutenção do meio ambiente sadio. Quanto à metodologia, trata-se de uma pesquisa pura, qualitativa e descritiva. O método de abordagem foi o indutivo crítico, de interpretação lógico-gramatical e procedimento técnicos documentais.

ABSTRACT
The aim of this study is to analyze the phenomenon of waste exportation, here referred to as international waste trafficking, in order to classify it as a transnational crime, since its effects clearly cross the borders of states, causing direct and/or indirect harm to the whole community. In order to achieve the proposed objective, this assessment followed the following order: the national and international legal treatment of waste is presented; an analysis is made of the sustainability of the export of this waste in order to characterize the export of waste as a transnational illicit practice. In the light of final considerations, the hypothesis is confirmed, showing that the shipment of waste to countries that will be responsible for its treatment and processing, in fact, is a transnational crime, because it clearly affects sustainability and compromises the maintenance of the healthy environment. Regarding the methodology used, it is a pure, qualitative and descriptive research. The method of approach was the critical inductive, logical-grammatical interpretation and documentary technical procedure.
