Interleukin-1 (IL-1) signaling is essential for controlling virulent Mycobacterium tuberculosis (Mtb) infection since antagonism of this pathway leads to exacerbated pathology and increased susceptibility. In contrast, the triggering of type I interferon (IFN) signaling is associated with the progression of tuberculosis (TB) disease and linked with negative regulation of IL-1 signaling. However, mice lacking IL-1 signaling can control Mtb infection if infected with an Mtb strain carrying the rifampin-resistance conferring mutation H445Y in its RNA polymerase β subunit (rpoB-H445Y Mtb). The mechanisms that govern protection in the absence of IL-1 signaling during rpoB-H445Y Mtb infection are unknown. In this study, we show that in the absence of IL-1 signaling, type I IFN signaling controls rpoB-H445Y Mtb replication, lung pathology, and excessive myeloid cell infiltration. Additionally, type I IFN is produced predominantly by monocytes and recruited macrophages and acts on LysM-expressing cells to drive protection through nitric oxide (NO) production to restrict intracellular rpoB-H445Y Mtb. These findings reveal an unexpected protective role for type I IFN signaling in compensating for deficiencies in IL-1 pathways during rpoB-H445Y Mtb infection.

Este artículo presenta los resultados obtenidos en la investigación acerca del desarrollo de la competencia informacional en los estudiantes de primer año de la Facultad de Ingeniería de la Universidad de Santiago de Chile. La perspectiva desde la que abordamos el estudio de la competencia informacional de los estudiantes parte de la idea de que esta competencia forma parte esencial de la competencia profesional de los futuros ingenieros(as). Mostramos los resultados del comportamiento de la Competencia Informacional Auto-percibida (CIA) y Competencia Informacional Observada (CIO) en las cuatro sub-competencias de la competencia informacional. Se aplicaron para ello técnicas de análisis factorial para la reducción de dimensiones, con el propósito de eliminar la redundancia entre las variables originales; con dicha reducción se identificaron cinco componentes claves. También, se detectaron sub-interrelaciones entre las sub-competencias de la competencia informacional que pueden generar sinergias locales al interior de la competencia. Se destaca que de las cuatro sub-competencias, la búsqueda de información es la que presenta mayores dificultades en la autopercepción como en la competencia observada; mientras que la competencia observada de comunicación de información fue la mejor evaluada. No se encontraron diferencias estadísticamente significativas entre las variables demográficas y los niveles de desarrollo de la competencia informacional.

Published: April 2024

Water stress significantly affects on rice yield and quality. Eight Japonica varieties from the first and second accumulated temperature zones of Heilongjiang Province were used as materials and four moisture gradients (0, −10, −25 and −40 kPa) were conducted at the grain-filling stage to clarify the effect of water stress on the rice yield and quality in cold regions. The results showed that the rice yield was reduced due to the decrease in the seed setting rate. Rice chalkiness was significantly increased by drought stress, especially under −10 kPa. The protein content of most varieties was significantly reduced and taste quality was increased under −25 to −40 kPa. The effect on protein components increased with increasing drought stress. The gel consistency decreased and the average chain length of amylopectin was less affected by drought. With an increase in moisture deficit, the rapid viscosity analyzer characteristics and chain length distribution of amylopectin showed a trend of first increasing and then decreasing or decreasing and then increasing. The response of starch to mild and severe drought varied. Our study provides a theoretical basis for the efficient utilization of water and high quality and yield of Japonica rice.

Published: April 2024

This work presents an adaptive model predictive control (MPC) strategy to suppress the vibration in a laminated composite beam. The control method incorporates a system identification algorithm to estimate the system parameters online, which provides a precise simulation of system dynamics. A fixed-free cantilever composite beam equipped with piezoelectric actuators was used to evaluate the efficacy of the control method. The sensors and actuators are securely bonded to the upper and lower surfaces at arbitrary locations along the beam’s length. A unified mechanical displacement field is applied to all layers, while displacements are considered independently for each layer. The beam is composed of eight layers of material, each with a thickness of 0.2 mm and orientations specified as (90°/0°/90°/0°). To achieve the best performance, the parameters of the MPC were adjusted numerically. The numerical analysis revealed that placing the actuator near the clamped end at the fixed end resulted in superior control outcomes, with a settling time of approximately 1.8 s. Conversely, the longest settling time occurred when the actuator was positioned at the free end, taking around 4 s. This model could potentially be expanded to address vibration in more intricate beams exhibiting nonlinear characteristics. The deflection readings measured at the end of the beam have been utilized as feedback control signals for predicting future behavior over a predetermined control horizon. The subsequent cost function is minimized through a quadratic equation to determine the sequence of optimal yet constrained control inputs. The suggested active vibration control system is then implemented and assessed numerically to examine the effectiveness of the control method.

The energy bound-state solutions of the spinless Salpeter equation (SSE) have been obtained under a spin-dependent Cornell potential function via the Wentzel–Kramers–Brillouin approximation. The energy levels were applied to predict the mass spectra for the charmonium, bottomonium, and bottom-charmed mesons. The relativistic corrections for the angular momentum quantum number

, and the radial quantum numbers n = 1–4 improve the mass spectra. The results agree fairly with experimental data and theoretic results reported in existing works, where the authors utilized different forms of the inter-quark potentials and methods. The deviation of the obtained masses for the charmonium and bottomonium from the observed data yields a total percentage error of 3.32 and 1.11%, respectively. The results indicate that the accuracy of the masses is correlated with the magnitude of masses for the charm and bottom quarks. The SSE together with the phenomenological spin-dependent Cornell potential provides an adequate account of the mass spectroscopy for the heavy mesons and may be used to predict other spectroscopic parameters.
Mechanical testing and engineering applicability analysis of SAP concrete used in buffer layer design for tunnels in active fault zones
Authors: Jun Cao , Zheshu Wu , Zhen Cui , Xiancheng Mei
Published: April 2024

To tackle the challenge of dislocation damage when tunnels traverse active fault zones, this study introduces the concept of using brittle buffer materials for anti-dislocation. Building on this concept, we propose a novel concrete buffer material utilizing large-sized spherical super absorbent polymers (SAP) as a porogen, aimed at ensuring the safety of tunnel structures during active fault dislocations. To investigate the feasibility and superiority of SAP concrete as a buffer material compared to other similar materials, we prepared samples with three different SAP concrete proportions and conducted a series of physical and mechanical tests. The results show that SAP pre-hydrated with 0.2 mol·L−1 sodium carbonate solution exhibits a slower rate of moisture loss in the cement slurry, aiding the hydration reaction of concrete. The permeability coefficient of SAP concrete is approximately 10−7 cm·s−1, slightly lower than foam concrete of the same density level. SAP concrete buffer material demonstrates significant brittleness, in contrast to the mostly ductile nature of other buffers such as foam concrete and rubberized concrete. Utilizing the brittle nature of SAP concrete materials, when applied to tunnels affected by stick–slip active fault dislocations, its instantaneous loss of compressive capacity provides excellent yield performance, thus protecting the tunnel lining from damage. However, under certain circumferential pressure conditions, both the peak and residual strength of SAP concrete significantly increase. High peak and residual strengths do not favor the effective buffering effect of SAP concrete; therefore, an approach involving the intermittent arrangement of precast buffer blocks has been proposed for application.
The ACE2/Ang-(1-7)/MasR axis alleviates brain injury after cardiopulmonary resuscitation in rabbits by activating PI3K/Akt signaling
Authors: Cheng Jing , Yang Hong , Chen Fang , Qiu Li , Chen Fang , Du Yanhua , Meng Xiangping
Published: April 2024

Background

Death among resuscitated patients is mainly caused by brain injury after cardiac arrest/cardiopulmonary resuscitation (CA/CPR). The angiotensin converting enzyme 2 (ACE2)/angiotensin (Ang)-(1-7)/Mas receptor (MasR) axis has beneficial effects on brain injury. Therefore, we examined the roles of the ACE2/Ang-(1-7)/MasR axis in brain injury after CA/CPR.

Method

We used a total of 76 male New Zealand rabbits, among which 10 rabbits underwent sham operation and 66 rabbits received CA/CPR. Neurological functions were determined by assessing serum levels of neuron-specific enolase and S100 calcium-binding protein B and neurological deficit scores. Brain water content was estimated. Neuronal apoptosis in the hippocampus was assessed by terminal deoxynucleotidyl transferase dUTP nick end labeling assays. The expression levels of various genes were measured by enzyme-linked immunosorbent assay and western blotting.

Results

Ang-(1-7) (MasR activator) alleviated CA/CPR-induced neurological deficits, brain edema, and neuronal damage, and A779 (MasR antagonist) had the opposite functions. The stimulation of ACE2/Ang-(1-7)/MasR inactivated the ACE/Ang II/AT1R axis and activated PI3K/Akt signaling. Inhibiting PI3K/Akt signaling inhibited Ang-(1-7)-mediated protection against brain damage after CA/CPR.

Conclusion

Collectively, the ACE2/Ang-(1-7)/MasR axis alleviates CA/CPR-induced brain injury through attenuating hippocampal neuronal apoptosis by activating PI3K/Akt signaling.

Published: April 2024

The autonomic nervous system (ANS) regulates the body's physiology, including cardiovascular function. As the ANS develops during the second to third trimester, fetal heart rate variability (HRV) increases while fetal heart rate (HR) decreases. In this way, fetal HR and HRV provide an index of fetal ANS development and future neurobehavioral regulation. Fetal HR and HRV have been associated with child language ability and psychomotor development behavior in toddlerhood. However, their associations with postbirth autonomic brain systems, such as the brainstem, hypothalamus, and dorsal anterior cingulate cortex (dACC), have yet to be investigated even though brain pathways involved in autonomic regulation are well established in older individuals. We assessed whether fetal HR and HRV were associated with the brainstem, hypothalamic, and dACC functional connectivity in newborns. Data were obtained from 60 pregnant individuals (ages 14–42) at 24–27 and 34–37 weeks of gestation using a fetal actocardiograph to generate fetal HR and HRV. During natural sleep, their infants (38 males and 22 females) underwent a fMRI scan between 40 and 46 weeks of postmenstrual age. Our findings relate fetal heart indices to brainstem, hypothalamic, and dACC connectivity and reveal connections with widespread brain regions that may support behavioral and emotional regulation. We demonstrated the basic physiologic association between fetal HR indices and lower- and higher-order brain regions involved in regulatory processes. This work provides the foundation for future behavioral or physiological regulation research in fetuses and infants.

This research aimed to know the perspective of high school students regarding the preparation of research reports and all those aspects related to format, resources and participation in projects and activities carried out at the national level in the country’s technical high schools, which seek educational and professional growth through research and the creation of proposals. The research was conducted under a qualitative approach of an exploratory and descriptive type, with the participation of 98 students from three technical high schools, who study the specialties of Executive Secretariat, Accounting, and Tourism. Aspects such as the frequency with which they carry out research, the format, topics of interest, obstacles, and frequent errors when carrying out research, as well as the educational and personal resources they have were consulted. The result was that, for the students, it is important to investigate and they project themselves as technological researchers who take advantage of the applications and the ease of searching for instant and free information, who are knowledgeable about the format and writing regulations but face obstacles such as little intrinsic and extrinsic motivation, the lack of soft skills necessary to work as a team, and the lack of knowledge in the research process.
La calidad estética como objeto de investigación en contextos educativos. Un ensayo sobre la normatividad de lo pedagógico y lo estético
Authors: Willatt Carlos , Castro-Sosa Daniela , Salinas-Trujillo Romina , Vásquez-Orrego Valentina
Published: April 2024

The notion of aesthetic quality addresses a dimension of educational processes that is still scarcely explored and linked to various modes of sensitive perception in pedagogical times and spaces. Regarding aesthetics as a constitutive dimension of educational quality in general, we examine two critical aspects for its research: 1) the normative implications of the notion of quality; 2) the normative distinctions that operate implicitly or explicitly in the pedagogical and aesthetic realm. The essay is developed in four moments. First, we present the state of the art of the research on aesthetic quality in Chile drawing on the example of research on school environment. Second, we analyze the difficulties posed by this notion in pedagogical and aesthetic terms. Third, we distinguish three types of normativity in this kind of research (perceptual, aesthetic and pedagogical). Finally, we offer some reflections on the scope and limits of researching this notion.

Published: April 2024

This qualitative research paper explores the reality that freshman students lived in the Bachelor’s Degree in English Teaching at Universidad Nacional, Coto Campus, Brunca Region, during remote-teaching classes in 2021 with regard to accessibility, competence, and the importance of Information and Communication Technologies (ICTs) and Learning and Knowledge Technologies (LKTs). The information gathered shows that the competence in using these tools was very poor due to the students’ not having enough knowledge at the beginning of the semester. Also, the access to ICTs and LKTs was limited because of different factors that tend to happen in rural areas; therefore, it is necessary to work on trainings and the accessibility to these devices in the Brunca Region. However, the ICTs and LKTs were important to the learning and teaching process of these students because the results show that without these tools, the access to the lessons would not have been possible nor the development of the four linguistic skills of the English language.

Published: April 2024

In this work, the effect of this microalga on the larval rearing of sea urchin Paracentrotus lividus was evaluated, and its use alone (D3) was compared with the application of multi-species diets (D1- Skeletonema costatum + Rhodomonas spp.+ P. tricornutum; D2- S. costatum + Rhodomonas spp.). To evaluate the success of the three diets, the development and survival of larvae fed the three diets was analyzed over 18 days. It was found that larvae fed the D3 diet grew and developed significantly faster than the other two diets (D1 and D2), but survival was significantly lower. To better understand the relationship between the larvae and their food, the fatty acid profile of the larvae fed the three diets was analyzed. The fatty acid profile of the three microalgae used was also analyzed. A correlation between the constitution of the larvae and their food was found, and the biosynthesis of some polyunsaturated acids, such as 20:5ω3 (EPA), 20:4ω6 (ARA), and 16:4ω3, was also verified. Despite the high nutritional value of P. tricornutum, it was found that this alga has a high EPA/ARA ratio, a ratio that may reduce larval survival. However, the association of this microalgal species with other species may contribute to improve the overall success of larval rearing.

Published: April 2024

The purpose of this study is to explore early childhood teachers' perceptions of borderline infants. To this end, seven early childhood teachers currently working at early childhood education institutions were analyzed using FGI (Focus Group Interview) to identify which infants are recognized as borderline infants, what difficulties they have in their relationship with borderline infants, and what they think are the ways to help borderline infants adjust to kindergarten smoothly.
As a result of the study, first, as implications for borderline infants, early childhood teachers considered ‘unbearable ambiguous infants’, ‘infants who cannot communicate at all’, and ‘infants who have difficulty establishing social relationships’ as borderline infants. Second, the necessary conditions for borderline infants were ‘the teacher's ungiving mind’, ‘communication and cooperation with guardians’, and ‘support systems inside and outside kindergartens’. The results of this study can be used as basic data to find ways to support young children's adaptation to kindergarten by understanding the meaning teachers experience in the process of guiding borderline infants in the kindergarten field.

Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea in a Young Child With Down Syndrome
Authors: Wasserman Isaac , Chieffe Douglas J. , Gipson Kevin S. , Skotko Brian G. , Hartnick Christopher J.
Published: April 2024

Obstructive sleep apnea (OSA) is common in children with Down syndrome (DS). Adenoidectomy and/or tonsillectomy are the usual first interventions employed to treat OSA in children with DS but sometimes do not achieve adequate resolution of clinical signs. Positive airway pressure treatment is often used next, but this treatment is poorly tolerated by this population. Persistent OSA can adversely affect a child’s health and cognitive development. Hypoglossal nerve stimulation (HGNS), previously shown to be safe and effective in adults with OSA, has been used in children as young as 10 years old with DS and has achieved measurable neurocognitive benefits. The US Food and Drug Administration recently lowered the age for HGNS implantation to 13 years for children with DS. However, questions remain regarding treatment of refractory OSA in younger children. Here, we report the case of a 4-year-old boy with DS and treatment–refractory OSA who underwent successful HGNS implantation. The decision to proceed with HGNS implantation in such a young child involved discussions about anatomic feasibility and potential neurocognitive benefits. The device was implanted without complication and with minimal postoperative bulk. This case suggests a possible treatment option that can be discussed in the course of shared decision-making between clinicians and families of young children with DS and treatment–refractory OSA.
Особливості сезонного розвитку Juglans regia L. у Правобережному Лісостепу України
Authors: Mahuran Volodymyr , Osadсhuk Leonid
Published: April 2024

Досліджено особливості сезонного розвитку горіха грецького (Juglans regia L.) у кліматичних умовах Правобережного Лісостепу України впродовж 2019-2021 рр. Встановлено, що в умовах регіону першими розпочинають вегетацію дерева горіха грецького у полезахисних і плантаційних насадженнях, а ці фенофази у лісових фітоценозах настають пізніше на 12-14 діб. Такий інтервал може бути зумовлений впливом агротехнічних умов, грунтовими і гідрологічними особливостями та іншими чинниками, які визначають розвиток рослин у різних екосистемах.

Тривалість вегетаційного періоду плантаційних насаджень на території Правобережного Лісостепу становить у середньому 183 доби, а лісових деревостанів – 186 діб. Сорти горіха грецького 'Вебу 6' та 'Єфрем 1', вирощені на території Вінницької області, вегетують упродовж меншого періоду часу порівняно з місцевими, американськими та європейськими сортами й формами. Подібні особливості визначено також щодо термінів і темпів росту й розвитку – дослідні сорти горіха грецького починають розвиватися раніше й раніше завершують ріст, що характеризує їх як більш зимостійкі.

Отримані результати також вказують на істотну різницю між найбільш ранніми та найбільш пізніми датами настання фенологічних фаз горіха грецького на дослідних ділянках. Це свідчить про важливі генетичні особливості цього деревного виду, які визначають необхідний інтервал часу та суму ефективних температур для його нормального розвитку.

Кліматичні умови Правобережного Лісостепу сприятливі для широкого культивування сортів горіха грецького – 'Вебу 6' та 'Єфрем 1'. Їхній фенологічний ритм відповідає тривалості вегетаційного періоду на території Правобережного Лісостепу.   

Настання кожної фенологічної фази вегетації горіха грецького залежить від генетично зумовленого інтервалу часу, а сезонні ритми розвитку є виявом його пристосування до змін у навколишньому середовищі. Дати фенологічного розвитку сортів 'Вебу 6' та 'Єфрем 1' не виходять за межі сезонних ритмів в умовах Правобережного Лісостепу, тому ці сорти є перспективними для використання у цьому регіоні.

A wide range of climatic conditions in Ukraine causes significant regional differences in the vulnerability of forests to the current rapid climate change. The mitigation/adaptation strategy should be based on assessments of their vulnerability at the regional level.

Phytoindication model by Prof. Y.P. Didukh was used to assess forest vulnerability. The model provides a quantitative estimation of climate as one of the major environmental factors affecting the distribution, condition and productivity of vegetation on the base of climate-related indicators – continentality, humidity and frost. For these indicators climate suitability scales were calculated. The modeling was carried out for the main forest species: Pinus sylvestris L., Quercus robur L., Fagus sylvatica L., Picea abies (L.) H. Karst, Betula pendula Roth., Alnus glutinosa (L.) Gaertn. and Robinia pseudoacacia L. Climate projections based on the Euro CORDEX time series (up to 2100) and 2 scenarios of the Representative Concentration Pathways (RCP 4.5, RCP 8.5) were used. Using Q-GIS, the maps containing zones of suitability to climate for each of the studied species were created for current climate conditions and future time series.

The directions for strengthening the mitigation and adaptive capacity of forests are considered. The mainstream for nature-based solutions is adaptive sustainable forest management, which provides: 1) optimization of land use structure and increasing the forested area; 2) development and implementation of a national forestry program considering the priorities of climate change and low-carbon development; 3) using wood to substitute greenhouse gas intensive-materials and fossil fuels; 4) the best forestry practices through the introduction of modern Climate-Smart Forestry principles.
Russian Invasion: Rapid Assessment of Impact on Ukraine’s Forests

The War has had serious effects on Ukraine’s forests, in the form of direct damage and fires caused by various munitions. Important damage, though, includes extensive minefields, dud ordnance, and booby traps which are causing forests to be closed to all activities. A study using remotely sensed data reveals that in 2022, more than 70,000 ha of the forests suffered severe destruction and damage due to shelling, fires, and illegal logging by occupying forces. Substantial efforts and innovative strategies are needed to address reforestation and restoration in the face of future climate change. In much of the steppe region and adjacent areas, forests and shelterbelts have been under stress already. The loss of shelterbelts in these regions can compromise future harvests due to rising droughts, sandstorms, soil erosion, and other environmental challenges  Important damage, though, is not visible in drone images: extensive minefields, dud ordnance, and booby traps are causing forests to be closed to all activities. Simply completing damage  assessments and developing plans for addressing these issues will be an enormous task, involving all agencies, private groups, and local governments concerned with forests, and with international support.  Difficult decisions on priorities will be required. Planning is underway on an international basis for programs of demining, bolstering fire management systems, and initiating restoration programs. An overstressed forest fire control system will need to be redesigned to handle future challenges. Shelterbelts will in many instances recover naturally on their own as it will be too hazardous for active restoration measures until demining is done, a task that will take decades.  Full restoration of normal, safe activity in the rural areas and forests will only be achieved generations in the future. This paper presents a rapid assessment of the immediate issues and important longterm concerns.
Estableciendo Diferencias En Los Indicadores De Calidad Entre Las Universidades Regionales
Authors: Fernández Labra Jorge
Published: April 2024

Este trabajo tiene un carácter exploratorio y pretende aplicar un conjunto de indicadores duros y que se construyen en base a información pública para medir la calidad institucional de las universidades públicas regionales. Se pretende establecer la existencia de diferencias muy relevantes en cuanto a calidad, en este universo relativamente homogéneo de universidades que disponen de una cantidad similar de recursos financieros, están reguladas por el mismo cuerpo legal y tienen una estructura similar de gobierno. Si se encuentran diferencias apreciables, éstas podrían explicarse por la calidad de la gestión institucional. Un segundo objetivo consiste en comparar los resultados del instrumento aplicado, con los años de acreditación otorgados por la CNAP a cada institución, con el objeto de establecer si se da cierta correlación entre ambos estadísticos.
APRESENTAÇÃO - A IMPRENSA DO SÉCULO XIX: UM OLHAR HISTÓRICO-COMUNICACIONAL

Published: April 2024

Este capítulo tem como intenção apresentar e, ao mesmo tempo, refletir sobre questões centrais que atravessam todo o livro, cujo objetivo é a realização de uma história da imprensa brasileira no século XIX a partir da perspectiva histórico-comunicacional. Mas por que colocar em evidência um olhar que religa e relaciona a comunicação e a história? Não haveria já centenas de trabalhos que se ocuparam do século XIX e sua imprensa? O que estas reflexões aqui contidas diferem ou se aproximam das muitas interpretações já produzidas sobre a imprensa? E, sobretudo, o que estamos denominando um olhar histórico-comunicacional?
TEMPOS DE INDEPENDÊNCIA: CIRCUITOS COMUNICACIONAIS DA IMPRENSA NO SÉCULO XIX
Authors: Carlos Barbosa Marialva
Published: April 2024

Há uma espécie de consenso em reconhecer que a expansão de periódicos no território brasileiro desde as vésperas da independência se insere no movimento mais amplo de formação de uma opinião pública que fazia também dos impressos a possibilidade de ecoar opiniões em torno do momento político em que se vivia. Só no Rio de Janeiro, a cidade imperial, começam a circular, em 1821, dez jornais; e entre 1821 e 1822, surgiram 21 novos periódicos. Mas este movimento também se estenderia por muitas províncias em todo o extenso território.

Quando o primeiro jornal começou a circular na província de São Pedro do Rio Grande do Sul, em 1827, já havia imprensa no Brasil há quase duas décadas. Com o Diário de Porto Alegre, damos início a esse capítulo no qual percorremos cerca de 70 anos da história da imprensa no Rio Grande do Sul, com foco em alguns movimentos que marcaram esse período: as primeiras folhas noticiosas, os jornais revolucionários, os jornais literários, a imprensa das mulheres e a imprensa negra, os primeiros cronistas e o surgimento do Correio do Povo, já no final do século XIX para o século XX. Para isso, reunimos resultados de pesquisas encerradas e em andamento, realizadas no âmbito das diferentes instituições de ensino que abrigam os autores deste texto.
Mathematical Modeling of Elastically Deformed States of Thin Isotropic Plates Using Chebyshev Polynomials
Authors: Germider Oksana V. , Popov Vasily N.
Published: April 2024

Abstract. In this paper a method for solving an inhomogeneous biharmonic equation while modeling elastically deformed states of thin isotropic rectangular plates using a system of orthogonal Chebyshev polynomials of the first kind is proposed. The method is based on representation of a solution to the initial biharmonic equation as a finite sum of Chebyshev series by each independent variable in combination with matrix transformations and properties of Chebyshev polynomials. The problem is examined for the case when a transverse load acts on the plate, and the hinge fastening along the edges of the plate is taken as boundary conditions. Using the extremes and zeros of Chebyshev polynomials of the first kind as collocation points, the boundary value problem is reduced to a system of linear algebraic equations. Decomposition coefficients of desired function with respect to Chebyshev polynomials act as unknowns in this system. As the comparison showed, the results obtained by this method with a high degree of accuracy coincide with similar results derived using analytical approach that are given in the article. The paper also presents the results of calculations using the proposed method in the case when two opposite edges of the plate are pinched and two others are pivotally fixed. The comparison with similar results of modeling the stress-strain states of rectangular plates which are presented in the open sources is carried out.
