Relationship between time perspective and proactive coping behavior in future dialectologists
Authors: Bekhter Anna A. , Skoreva Anastasia N.
Published: September 2023

The relevance of this study is due to the problem of professional training of future dialectologists in the context of distance learning over the past two years. Taking into account the special requirements for the personal qualities of the future dialectologist, the question arises of proactive skills for coping with a difficult situation and a clearly built time perspective in today's situation of uncertainty. The purpose of the study is to determine the relationship between the time perspective and proactive coping behavior in future speech pathologists of different areas of training. The results of an empirical study of 80 students studying in the direction of «Special Psychology and «Speech Therapy» aged 18 to 43 years (M = 22.5; SD = 6.394) are presented. The following methods were used in the study: Proactive Coping Inventory (PCI) in adaptation by E.P. Belinskaya et al., R. Schwarzer's scale «Proactive attitudes» (adapted by A.A. Bekhter), Time Perspective Inventory by Philip George Zimbardo in adaptation by A. Sircova et al. An analysis of correlations showed that proactive coping in future dialectologists is positively associated with a positive past and the search for emotional support. In special psychologists, links have been found between negative past and preventive coping, which distinguishes them from future speech therapists, who have found positive links between seeking instrumental support and a positive past. Differences were also established between future special psychologists and speech therapists in terms of the hedonistic present, future and positive past. The results of the study allow us to expand the scientific understanding of the relationship between the time perspective and proactive coping behavior in future speech pathologists.
STUDY OF THE ANTISTATIC PROPERTIES OF MATERIALS TREATED WITH COLLOIDAL COMPOSITIONS BASED ON METAL NANOPARTICLES
Authors: Antonova Marina V.
Published: September 2023

The article provides a short overview of the application of metal nanoparticles in the textile indus- try, describes their properties and application`s fields. The definitions of electrification, electrostatic field, electric charge density are given. The application of processing of fabrics by polyurethane dispersion and metal nanoparticles in technological processes of textile materials finishing is justified. The objects of the study are cotton fabric`s samples with addition of synthetic fibres, colloidal solutions of silver and copper nanoparticles, aqueous polyurethane dispersion. The antistatic properties of the fabrics have been studied. The electrostatic field intensity of the samples was measured on the device ST-01, with the density of the electric charge calculating according to the intensity values. It has been experimentally established, that the processing of fabrics by solutions of nanoparticles of metals contributes to reduction of intensity of their electrostatic field to 65 %, compared with the initial samples. It is noted that treatment of fabrics by polyure- thane dispersion in combination with copper nanoparticles gives no clear antistatic properties to the blended fabrics.

Authors: Rudovskiy Pavel N. , Belova Irina S. , Sakharova Nina S.
Published: September 2023

The strength of spinning products formed by the wet finning method is determined by the adhesion forces that arise between the contacting fibers. To predict the strength of yarn and roving obtained in this way, it is necessary to know the number of fiber contacts in the cross section of the product. Studies of the distribution of fibers in the section of linen roving have been carried out and a method for determining the number of fiber contacts has been proposed. The initial data are digitized images of roving sections obtained using a digital microscope. After threshold processing of the image, the perimeters and areas of continuous sections occupied by fiber sections were calculated. The area of a single fiber is defined as the average area of the five smallest sections in the section. Based on the analysis of these data, a mathematical model of the dependence of the number of contacts between fibers on the perimeter of the section of the spinning product was constructed.

Published: September 2023

The article considers the problem of predicting the moisture exchange of textile materials in a wet state using the example of knitted fabrics for underwear. Based on the thermodynamic analogy of heat and moisture transfer processes, an experimental scale of the moisture transfer potential of a reference body was constructed. As a result of the study of the mass transfer system “sample – reference body”, the mass transfer characteristics of several knitted fabrics were obtained. Thermodynamic relations are obtained for calculating the intensity of moisture transfer of textile materials in a bag of clothes. The results of calculations are given on the example of the selected samples. The results of the calculations made it possible to establish the relation- ship between the moisture flux density from the sample and the value of the moisture transfer potential. Signifi- cant differences between these flows have been established. The data obtained make it possible to make a fore- cast about the operational efficiency of clothing with various options for the material of the linen layer.

Authors: Mamedova Irina Yu. , Churin Alexey S. , Оranskaya Irina A.
Published: September 2023

This article examines in detail the current issue of originality of design objects created using neur- al networks, and denotes that the degree of originality of the result depends on various factors, such as the complexity of the query, the degree of transformation of the original visual image, and the use of various non-neural network models. The article focuses on the importance of understanding artistic originality and plagiarism in design, which helps define the boundaries between unique and borrowed creativity. A careful analysis of the findings led to the conclusion that there is a significant correlation between the formulation of the query and the originality of the resulting image. Thus, in order to achieve the most unique and creative results, it is necessary to carefully approach the formulation of initial queries and the choice of neural net- work parameters.

Published: September 2023

The article describes the basic concepts of topology, which are fundamental for specialists in the field of three-dimensional design. All polygons can be divided into triangles, squares and n-gons, and of these polygons are the most undesirable. To consider this statement, a number of models of varying complex- ity have been developed and transferred to the UNITY game engine in two forms obj and fbx. Both formats are the most commonly used in game design, character design, locations, or object modeling, but they con- vert the polygonal grid of an object in different ways, which is why the shape of the model itself will change in the presence of n-gons.

Authors: Tafirenyika Nancy , Van den Berg Geesje
Published: September 2023

Distance learning in South Africa has been experiencing the unfortunate occurrences of low student throughput and retention. Therefore, the purpose of this paper was to determine possible strategies for sustained learning. Framed by Ubuntu as its theoretical perspective, the researchers discovered valuable insights through a methodological literature review and an empirical inquiry. Eight undergraduate students reflected on their distance learning experiences and challenges and suggested strategies for sustained learning. From an interpretivist research paradigm supported by a qualitative research approach, the study used a case study to conduct semi-structured interviews to gather data at an open distance learning institution in South Africa. The findings indicate that distance education institutions should provide sufficient learning support; conduct surveys to determine student challenges and needs; improve communication with students; develop a hotline; use open education resources and provide financial aid to all disadvantaged students. The study argues that the values of Ubuntu as set out in this paper, should be considered when drafting policy and implementing strategies to support students
Using ICT-based pedagogy to teach English First Additional Language during the COVID-19 pandemic: A rural case study
Authors: Maja Margaret
Published: September 2023

During the COVID-19 pandemic, face-to-face teaching was suspended and teachers were forced to transition to online teaching supported by information and communication technology (ICT)-based pedagogy. This study explored how teachers used ICT-based pedagogy to facilitate EFAL learning during COVID-19 in a rural area of Limpopo, South Africa. A qualitative descriptive case study was grounded in interpretivism and informed by teacher self-efficacy (TSE). Nine purposefully sampled EFAL teachers (four male and five female) were interviewed. Data were analysed using thematic analysis. The findings indicate that only two of the nine teachers employed ICT in online teaching and learning using social media platforms like WhatsApp and YouTube. Challenges such as the lack of teachers’ ICT knowledge and skill, lack of data bundles for internet connection and learners’ lack of digital devices emerged. The two teachers were unable to effectively provide online teaching to the learners due to a lack of adult support. It was concluded that only a few EFAL teachers were ready to apply ICT in their teaching on a permanent basis. This study recommends that in-service teachers’ training in the integration of ICT in the teaching and learning process is needed.
Assessing Student Support Services in Open and Distance Learning: The Case of Botswana Open University
Authors: Majaule Fidzani Agnes
Published: September 2023

ABSTRACT
To ensure that all students studying through the open and distance learning (ODL) system have enduring learning experience and success, there is a need for a practical and effective student support system. Research in the United Kingdom and elsewhere has shown that the rate of attrition is higher in ODL when compared to the conventional systems. In an ODL environment, student support services entail academic, psychosocial, and administrative support. Botswana Open University (BOU) is no exception to having pitfalls considering the queries raised by students. This study assessed the effectiveness of student support services in an ODL institution like BOU. The researchers adopted Tinto’s Student Integration Model as their theoretical benchmark. The model states that students are more likely to remain enrolled in an institution if they become connected to the social and academic life of that institution. A qualitative design involving interviewing tutors, students, heads of departments, tutor coordinators, and the student counsellor allowed for collection of data that was thematically analysed. The findings identified challenges related to administrative, academic and psychosocial support. Based on these findings, recommendations were made to improve student support services at BOU.

Analisis Komparatif Pemikiran Muhammad Syahrur dan Peraturan Perkawinan Irak Pasal 3 Ayat 4-5 Tahun 1963
Authors: Arisman Arisman , Harmanto Adi , Ariyadi Ariyadi
Published: September 2023

Ulama klasik dan konvensional tidak mensyaratkan perempuan janda yang memiliki anak yatim sebagai syarat mutlak keabsahan berpoligami. Pandangan tersebut berbeda dengan pandangan Muhammad Syahrur, ulama kontemporer, yang menyebutkan bahwa poligami hanya dapat dilakukan dengan perempuan janda yang memiliki anak yatim. Pendapat Syahrur ini, jika dilihat selayang pandang, menemukan implementasinya dalam Peraturan Perkawinan Irak yang masih berlaku hingga dewasa ini. Sejauh mana konsep poligami Syahrur terimplementasi dalam tubuh Peraturan Perkawinan Irak dan bagaimana ushul fikih memandang keakuratan konsep poligami Syahrur tersebut merupakan persoalan yang hendak dijawab dalam penelitian ini. Dengan penelitian berjenis library research dan metode deskriptif-analitis serta ditambah dengan pendekatan ushul fikih, penelitian ini menemukan bahwa konsep poligami Syahrur, walau belum seutuhnya, telah terimplementasi dalam Peraturan Perkawinan Irak. Hanya saja, dalam Peraturan Perkawinan Irak tidak disebutkan secara jelas apakah perempuan janda tersebut harus memiliki anak yatim atau tidak, Peraturan Perkawinan Irak juga terlihat begitu longgar, karena tidak memberlakukan syarat-syarat poligami umumnya terhadap perempuan janda, seperti keadilan sebagaimana Syahrur. Konsep poligami Syahrur, dalam lensa ushul fikih mengandung kelemahan dan kesesuaian. Kelemahannya adalah absennya teks-teks Hadis dalam ijtihad Syahrur yang merupakan sumber hukum penting dalam ushul fikih. Sedangkan kesesuaiannya adalah pengetatan pemberlakuan poligami Syahrur selaras dengan cita ushul fikih.

Published: September 2023

For Service Oriented Infrastructures (SOI) and Cloud services, monitoring and metering are crucial tasks. For the proper execution of cloud applications & the monitoring of SLA compliance, the data gathered through monitoring is required. The motivations for and challenges in monitoring and metering cloud systems are discussed. The methods for monitoring the network and execution environment on virtualized infrastructures will be discussed together with the monitoring tools that are now available on various commercial and research platforms. Every distributed computing system has a basic feature that includes monitoring chores. Every service should be watched over in order to evaluate its effectiveness and enable remedial measures in the event of failure. A functional snapshot of the system's behaviour along the time axis is what monitoring data reflects. Such information is essential for pinpointing the source of issues or for fine-tuning various system components. For example, failure detection and recovery procedures require a monitoring component to determine whether to restart a specific server or subsystem based on the data gathered by the monitoring system.
Zigbee based Wireless Sensor Network for Smart Energy Meter
Authors:   Department of Electronics Engineering Aligarh Muslim University, Aligarh (U.P) India,, Sharma Pratham
Published: September 2023

Wireless sensor networks are expanding across a wide range of application scenarios. The most widely used transmitter is "ZigBee," which is used in wireless sensor networks. Based on the IEEE standard known as IEEE 802.15.4, ZigBee is an enabling low-cost technology that offers minimal energy consumption and a low data rate. It is used for remote control, medical aid, home automation, industry control, and other wireless sensor applications, in addition to wireless sensor networks and personal area network applications. This paper aims to develop a wireless sensor network and a protocol for smart energy meter applications. Our proposed system comprises a digital energy meter, a ZigBee coordinator, and a management application. A terminal alert and a cover alarm can be automatically sent to the management software by the wireless meter reading system once it has read the unit. Mistakes from Errors in leakage metering reading to manual meter reading can be avoided. This proposed system will improve efficiency by reducing labor intensity to liberate labor and force. The system setup can accommodate a large number of energy meters with sufficient hop network depth to detect a new energy meter automatically. The technology can be widely used in wireless monitoring and control applications because of its low cost, low power consumption, extended battery life, and mesh networking's ability to extend high reliability to a broader range. To connect a variety of low-power devices wirelessly, ZigBee will satisfy the rising demand. For the future generation of industrial technologies, ZigBee will be deployed.

Published: September 2023

People with transtibial limb loss suffer from reduced mobility. Intelligent ankle-foot prostheses have the potential to improve quality of life in people with limb loss, but there are scientific, clinical, and commercial barriers that prevent widespread impact. Further research tools and experiments are needed to expand our understanding of how to design and control intelligent prosthetic limbs. We designed and built a robotic ankle-foot prosthesis with off-board actuation and control to serve as a platform for biomechanical lower limb loss research. Our prosthesis fits inside of a shoe during walking, and attaches to standard clinical prosthesis componentry, including carbon fiber prosthetic footplates and pyramid adapters. Our novel mechanical architecture implements a custom torsion spring in parallel with the ankle joint to allow for dorsiflexion and plantarflexion torque control with a single off-board actuator. Benchtop tests show that our prosthesis has peak plantarflexion torques greater than 175 Nm and a torque control bandwidth of 6.1 Hz. Walking experiments with two participants with lower limb loss indicate that the prosthesis can achieve low torque tracking errors and push-off power greater than the biological ankle during walking. This device will enable future experiments on amputee gait biomechanics, human-robot interaction, and prosthesis control.
Multihop MIMO Full-Duplex Relay Networks with Short-Packet URLLCs
Authors: Ngo Hoang Tu , Lee Kyungchun
Published: September 2023

In this study, we investigate multihop multipleinput multiple-output (MIMO) full-duplex relay (FDR) networks with short-packet ultra-reliability and low-latency communications (uRLLCs), where transmit-antenna selection/maximumratio combining and transmit-antenna selection/selection combining are leveraged as diversity techniques. Under quasistatic Rayleigh-fading channels and the finite-blocklength theory, the end-to-end block-error rate (BLER) performance of the considered FDR is analyzed and compared with that of halfduplex relaying systems, from which the effective throughput (ETP), energy efficiency (EE), reliability, and latency are also investigated. To analyze the diversity order and gain further insights into the system design, an asymptotic BLER analysis in the high signal-to-noise ratio regime is provided. However, the derived analytical expressions contain non-elementary functions, making them intricate for practical implementations, particularly in real-time configurations. Therefore, we have introduced a deep multiple-output neural network with short execution time, low computational complexity, and highly accurate estimation to overcome this hurdle. This network can serve as an efficient tool to rapidly respond to the necessary system parameters, such as transmit power and blocklength, when the services request specific ETP, EE, reliability, and latency. To corroborate the correctness of the theoretical analysis, extensive simulation results are provided under varying impacts of system parameters.

Authors: Onal Beyza , Kabaoglu Nihat
Published: September 2023

The tremendous advances in communication technologies require next-generation communication systems to be optimally designed in terms of speed, reliability, cost, energy consumption, spectral efficiency, ecosystem compatibility, and sustainability. With these requirements in mind, this paper discusses downlink millimeter wave communication for a large-scale multiple-input multiple-output system equipped with a group of intelligent reconfigurable surfaces, one of the potential candidates for 6G wireless networks, considering 5G physical mmWave channel models. In addition to the precoder, beamformer, and combiner design of the proposed system  model, the theoretical average pairwise error probability and achievable rate expressions are derived. Furthermore, an upper bound for the achievable rate is derived. Simulation results clearly show that the performance of the proposed model is close to the theoretical bounds of the performance metrics and clearly demonstrates its superiority compared to a similar model based on index modulation.

Objective. Individuals with Amyotrophic lateral sclerosis (ALS) progressively lose muscle functionality and therefore experience both an increased need for assistive robot technologies and a reduced ability to control such robots. While these individuals may use high-performing control systems, such as tongue control, at the beginning of their disease progression, they will eventually be restricted to a lower-performing control system, such as brain control. However, an adaptive multimodal control interface framework consisting of combinations of tongue control and noninvasive brain control can utilize the residual tongue functionality to optimize the control performance throughout the disease progression.

Approach. To investigate this concept, a new adaptive tongue-brain multimodal control framework for manual and continuous control of a 7-degree-of-freedom robot arm is developed, based on a prior validation study. The new framework focuses on improved visual feedback, as individuals with ALS specifically requested this in a previous validation study, and consists of four subsystems: the first uses full tongue control; the second and third use hybrid tongue and noninvasive brain control, with a decreasing need for tongue functionality; and the fourth uses noninvasive brain control only. The framework was evaluated with three participants with ALS.

Main results. All participants were succesful with all subsystems. One user could no longer efficiently use the full tongue control interface but achieved good results with the third and fourth subsystems. The second participant achieved significantly better results with the subsystems that included some tongue control, thereby showing the advantage of including some tongue control. The third participant performed well with all subsystems showing the ideal performance progression between each subsystem. Moreover, all participants, including the two with good tongue control, chose a multimodal control interface as their favorite.

Significance. The results indicate that individuals with ALS prefer interfaces that combine multiple control modalities.
Incompletely Polarized MIMO Radar for Target Direction Estimation
Authors: Shu Ting , He Jin , Wen Fangqing , Truong Trieu-Kien
Published: September 2023

MIMO radars with electromagnetic vector sensor (EMVS) antennas (also known as EMVS-MIMO radars) have been investigated intensively for target direction estimation in recent years. Many existing works on this topic are based on an unrealistic assumption that each EMVS antenna transmits six identically polarized and mutually orthogonal waveforms. Furthermore, target-fluctuation induced non-coherent backscattering in polarization has been entirely overlooked. This paper aims to develop a general transmit-receive signal model for EMVS-MIMO radar direction estimation. Specifically, by taking transmit polarization agility and/or polarization non-coherent backscattering into account, the collected pulse signals are no longer of complete polarization, but of incomplete polarization. By regarding an incomplete polarized (IP) signal as two incoherent completely polarized (CP) signals with the same azimuth-elevation directions and drawing upon the idea of ESPRIT, a new azimuth-elevation direction estimation algorithm is thus derived. The advantage of the new algorithm is that it can provide closed-form, automatically paired azimuth-elevation direction estimates and require no information on the location/displacement of the transmit-receive antennas. Finally, simulations are conducted to demonstrate the effectiveness of the proposed algorithm.

Among the available scientific literature, there are no publications addressing processes of self-regulation in the parasite-host population systems with reference to chronic infections, including the infection caused by the EpsteinBarr virus (EBV infection). The aim of the study is to assess manifestations of the epidemic process of chronic EBV infection through the lens of the basic tenets of the theory of self-regulation of parasitic systems. Materials and methods. The study was performed using data from scientific publications selected from such database sources as Scopus, Web of Science, Cochrane Library, PubMed, CyberLeninka, RSCI, etc. The list of analyzed publications included published articles of the authors of this study, reporting the results of the retrospective epidemiological analysis of the incidence of infectious mononucleosis in Russia in general and in Moscow in particular, as well as the results of the laboratory tests regarding the detection frequency of specific antibodies to EBV proteins. Results. The chronic course of EBV infection promotes a close long-term interaction between the pathogen and the host. The genetic variability of the pathogen and the functions of specific and nonspecific human immune defense systems play a key role in the interaction between two heterogeneous populations and underlie their phasal self-transformation. A variety of social and natural factors (adverse chemical, physical, biological, climatic impacts, etc.) trigger the reactivation of chronic EBV infection, thus providing the continuous existence of additional sources of infection in the host population. Conclusion. The analysis of the manifestations of chronic EBV infection in the context of the theory of self-regulation of parasitic systems promotes the understanding of the factors underlying the unevenness of its epidemic process. The obtained data can be adjusted for other infections having similar transmission mechanisms and virus life cycles (including other herpes infections) to map out strategies to control the epidemic process of chronic infections spread by aerosol transmission of the pathogen.

Introduction. The mouse-specific orthopoxvirus, ectromelia virus, is one of the best models that can be used to study key issues of pathogenesis, prevention, and treatment of smallpox, and to develop measures to increase virulence, transmissibility, or the ability to overcome vaccine immunity.
The aim of the work is to screen the antiviral activity of samples from Inonotus obliquus chaga and humic acid from brown coal in vitro against ectromelia virus.
Materials and methods. We used ectromelia virus, strain K-1 (reg. No V-142), obtained from the State Collection of Pathogens of Viral Infections and Rickettsioses of the State Scientific Center of Virology and Biotechnology Vector; Vero Е6 cell culture (No 70) from the Collection of cell cultures of the State Scientific Center of Virology and Biotechnology Vector. Nine samples from chaga I. obliquus and humic acid from brown coal were used to evaluate the changes in the infectivity of the ectromelia virus on cell culture using 2 schemes of application of drugs and virus (preventive and therapeutic schemes), and to assess their cytotoxicity and antiviral activity.
Results. 50% cytotoxic concentration, 50% virus-inhibiting concentrations and selectivity index were determined for all samples. The studied samples were shown to be non-toxic to the monolayer of Vero cell culture in a dilution of 300 and more micrograms/ml, while demonstrated high antiviral activity against strain K-1 of ectromelia virus in two application schemes preventive and curative.
Conclusion. All samples tested for ectromelia virus in vitro can be considered promising for further development of drugs against diseases caused by orthopoxviruses.

Introduction. African swine fever virus (ASF) is a large, enveloped virus with an icosahedral capsid morphology and a double-stranded DNA genome ranging in size from 170 to 190 kb. The replication cycle proceeds in two phases, the early phase lasting 46 hours and the late 820 hours after infection. The adaptation of the ASF virus to growth in continuous cell lines makes efficient and reliable genetic analysis and more accurate interpretation of its results.
Objective. Adaptation of a new isolate of the ASF virus to growth in a continuous cell line by the method of accelerated passages and preliminary genetic analysis of the resulting strain.
Materials and methods. For virus isolation and passaging of the ASF virus, a porcine leukocyte cell culture (PL) and continuous cell cultures of porcine origin (ST, PK, PPK-66b) were used with Eagle MEM and HLA essential media with 10% porcine or fetal serum.
Results. The article presents data on the isolation and analysis of the changes in the reproductive properties of a new African swine fever (ASF) virus isolate in the process of adaptation to growth in a continuous piglet kidney cell culture clone b (PPK-66b). The current state of the problem of cultivation of the ASF virus, the features of its reproduction, and the basis of the genetic differentiation of its isolates are described in detail. Understanding the uniqueness of the nature of the ASF virus determined the approaches to the processes of its cultivation and adaptation. In this regard, the results of studies of cultural properties, and analysis of the nucleotide sequence of 6 genes of the new isolate, as well as phylogenetic analysis of these genes with already known strains and isolates of the ASF virus are presented.
Conclusion. A new strain obtained in the process of cell adaptation of ASVF/Znaury/PPK-23 ASF virus by the accelerated passaging method reaches a high level of reproduction in 72 hours with an accumulation titer of 7.07 lg HAdE50/cm3. Primary genetic analysis allowed to establish the main phylogenetic relationships of the newly isolated strain with previously known variants of the current ASF panzootic.

A violência contra a mulher, o distanciamento masculino do cuidado em saúde primário e a discriminação contra as pessoas LGBTQIA+, lésbicas, gays, bissexuais, transgênero, queer, intersexo, assexual, são expressões do construto social de gênero que estão postas como desafios aos profissionais de saúde, que devem    desenvolver estratégias de enfrentamento a essas iniquidades sociais em saúde. Por outro lado, a ordem societária pautada na desigualdade de gênero cria barreiras de acesso aos serviços de saúde e consecutivamente aumentam as disparidades sociais. Este estudo objetivou identificar, na literatura, os fatores que contribuíram para a (re) produção da desigualdade de gênero no âmbito da Atenção Primária à Saúde brasileira. Para isso, foi realizada uma revisão integrativa da literatura, cuja amostra final foi composta por 40 artigos. A coleta de dados foi realizada nas bases de dados: Scientific Eletronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Os estudos foram selecionados por meio dos descritores controlados combinados com operadores booleanos: (Gender and Health OR Género y Salud OR Gênero e Saúde) AND (Primary Health Care OR Atención Primaria de Salud OR Atenção Primária à Saúde).  No corpus de analise, destacou-se a prevalência dos estudos qualitativos. Os estudos evidenciaram que, nos serviços de atenção primária, a concepção de gênero é orientado por preceitos biologizantes, frutos de um modelo de atenção em saúde biomédico que além de fragmentar as ações dos profissionais de saúde, impede que haja uma abordagem sociocultural de emancipação, corroborando assim para efetivação e naturalização da desigualdade de gênero.
