El mapa morfogenético del estado de Sonora a escala 1:750,000, comprende una superficie aproximada de 180,027 km2 y el objetivo de esta cartografía es relacionar la litología con el arreglo geomorfológico a través de la interpretación de la génesis del terreno. Los 44 sistemas de terreno morfogenético que componen el mapa fueron interpretados a partir de imágenes Landsat-7 con apoyo de información topográfica y litológica editadas en varios años. Pese a que la principal limitante de esta investigación es la gran cantidad de superficie por confirmar, la corroboración general se ha llevado a cabo en diversas campañas de trabajo de campo. La clasificación de sistemas morfogenéticos desde una perspectiva geológica-geomorfológica puede resultar interesante para una mayor cantidad de usuarios, pues simplifica en ella el origen, el tipo de materiales y el relieve. Este mapa morfogenético puede utilizarse como apoyo para estudiantes y profesionistas en el análisis y estudio del paisaje.

Published: May 2022

Abstract: Wind Energy Conversion Systems (WECS) show variability in their output power as a result of changing their main engines (wind speed). This introduces a new grid uncertainty factor and poses many challenges to electricity system designers and utilities in terms of grid network integrity, ie power system security, power system stability and power quality. This paper discusses the various challenges of wind energy when integrated into the grid and identifies different mitigation strategies for its smooth integration. Keywords: wind energy system, Power quality, Power filters, Reactive Power, controllers

Abstract: Structural materials are used in a machine tool have a key role in defining the productivity, accuracy and Size proportions of the part manufactured by machine tool. The conventional structural materials like cast iron and Stainless or carbon steel at high operating speeds but used in precision machine tools grow positional errors due to the vibrations transferred into the Machine tool structure. Faster cutting speeds can be achieve only by structure which has good damping characteristics and high stiffness. Clearly the life of a machine tool is proportional to the levels of vibration Produce by machine. The further Work is carried out to Study the deformation and natural frequency using Static analysis and Modal analysis respectively. The bed in machine tool Took Major role in the precision in components. It is one of the greatest vital tool structures which is absorb the vibrations resultant from the cutting operation. To analyse the bed for possible material changes and Structure changes that could increase stiffness, decrease weight, expand damping characteristics and segregate natural frequency at the operating range. So main enthusiasm behind the impression to go for a composite Material in model involving ultra-High Modulus Carbon Fibre Reinforced Polymer Composite Material (UHM CFRP). In a carbon has good stiffness and strength properties but its absences in damping requirements. On the other hand, polymers, though its deficiencies in strength but, good damping in characteristics and it is easily holding the carbon fibres. So, this is makes greatest combination of materials in an appropriate manner. In this work, a machine tool’s bed is selected for the analysis static loads. Then study is carried out to decrease the weight of the machine tool’s bed without affecting its structural rigidity. The 3D CAD model of the bed has been created by using commercial 3D modelling software and analyses were carried out using ANSYS 2021 R2. Keywords: Composite material, hybrid structures, Milling machine bed, UHM CFRP.

Crimped-type steel fibers are used. Fly ash and Alccofine have been used as mineral admixtures to fulfil the power requirement. Chemical admixture has also been used for workability. The test results of plain and fibrous HSSC concrete indicated that steel fiber increases the tensile strength and makes concrete more durable and impermeable Keywords: HSSCC, alccofine, tensile strength, durability
Women in Indian Freedom Struggle
Authors: Kaur Gurjeet
Published: May 2022

Abstract: The history of the struggle of Independence of India would be incomplete without describing the contribution of women. What the women of India have done is priceless. The history of the Indian freedom struggle is full of stories of women's sacrifice, altruism and valor. Very few of us know that there were hundreds of women who fought side by side with their male counterparts. They fought with true spirit and indomitable courage. Indian women broke away from various restrictions and left their traditional domestic roles and responsibilities. Therefore, the participation of women in the struggle for freedom and national awakening is incredible and commendable. However, it is not easy for women to fight as warriors in a male-dominated society. Even if women tried to change the perception of people so conservative who thought women are just there to do housework. Furthermore, women not only sacrifice their lives but also struggle with these issues. Rani Laxmi Bhai was one of those women who fought against the British. This paper is n attempt to highlight this legacy of women in history. Keywords: Indian, Women, Freedom movement, Role, Society

Published: May 2022

With advancements being accelerated in fields of Machine learning (ML), Deep Learning (DL), and the Internet of Medical Devices (IoMD), Artificial Intelligence (AI) has significantly evolved over the last decade. This transformation has opened doors for new possibilities of fostering AI in Medical Devices (AIMD) for applications that have not been explored before. With the current advancements in the computational capabilities, there has been a wide range of Medical Devices released in the global market, which are either supported by or driven by software to deliver its intended purpose. But with the advent of AI, software though built upon a string of codes has no restriction on the choices that it could make, since its essence lies on the deducing a decision based on a predictive analysis. This has called for rethinking our conventional approach towards the usage of Software in Medical Devices. Coupling with the rapid growth rate of these devices and their focus on delivering impeccable assistance to the facilitators who were doing things all by themselves previously, it also calls for a proper set of guidelines to regulate the usage of AIMD, considering its massive scalability and the gargantuan amounts of data that it brings along with it. This paper focuses on extrapolating the growth factors of AIMD along with the prerequisites that ought to be met by the organizations to prepare themselves for transforming and adopting this new technology. It also covers the aspects that are to be emphasized in regulating it in the forthcoming years.
Current situation and prospects of cooperation in the field of agriculture in the Chinese province of Heilongjiang and Russia
Authors:   Тhe Institute of Russia of the Heilongjiang Academy of Social Sciences, Zhang Mei
Published: May 2022

The Heilongjiang Province is the province of China that pioneered agricultural cooperation with Russia. After many years of development in the field of agriculture between the Heilongjiang Province and Russia, great results have been achieved, such as diversification of economic entities, diversification of forms of cooperation, constant and continuous expansion of areas of cooperation, etc. However, there are also the following problems: the first is the limited transit of labor and technical personnel; the second is the high cost of transit of agricultural machinery and auxiliary agricultural implements; the third is the difficult obtaining of financing for Chinese enterprises for the development of agriculture in Russia. Agricultural cooperation between the Heilongjiang Province and Russia has been hit hard since the start of the global epidemic of coronavirus pneumonia. However, against the backdrop of joint construction by Russia and China of the «Belt and Road» cooperation between two countries is a general trend, cooperation in the field of agriculture is still important for two countries to achieve mutual benefits and win-win results, and the field of action and prospects are very broad.
A voz oracular de Francisco Carvalho
Authors: Suttana Renato Nésio
Published: May 2022

Neste artigo, a poesia do poeta brasileiro Francisco Carvalho é estudada sob a perspectiva das suas aquisições formais, considerando-se o seu desenvolvimento temporal ao longo de seis décadas, e das características do imaginário que a perpassa. Partindo da ideia de que nela se realiza um encontro de tradições – no qual os ecos do Classicismo português se mesclam a uma linguagem francamente moderna ou derivada dos códigos da escrita modernista, amalgamados pela dicção própria do poeta, em que o diálogo entre tais elementos se afirma como vetor predominante, buscamos compreender o modo como certas imagens da vida empiricamente vivida, com suas determinações de tempo e lugar,  encontram na palavra poética do autor o seu contorno e o seu acabamento. A vida, nessas condições, não termina, mas também não começa, pois a abertura da obra no âmbito do imaginário a expande em todas as direções. Instaura-se assim um tempo de exílio que será tanto o tempo do mito e do imaginário, quanto o tempo daquilo que chamamos aqui de uma fala profética ou oracular, que não se deixa aprisionar pelas compartimentações da razão ou da memória. O voo da palavra escapa, sempre, para uma outra dimensão, onde todo evento de enunciação se converte imediatamente numa abertura ou numa ultrapassagem. Objetiva-se, no estudo, a partir da análise e do comentário da trajetória poética de Francisco Carvalho, compreender essas relações e interrogar o seu sentido.
Perdoar, a propósito de Derrida
Authors: Siscar Marcos
Published: May 2022

A partir de uma circunstância específica de enunciação, o texto aborda a relação de Derrida com a literatura e, em especial, com a poesia. Derrida se distancia das divisões e hierarquias internas do pensamento sobre os gêneros. Por outro lado, há diferenças perceptíveis no tratamento desses discursos, o que permite concluir que a divisão de gêneros é negada e reafirmada, ao mesmo tempo. Derrida valoriza o diálogo com obras poéticas, mas evita o conteúdo mundano e “disciplinar” associado à poesia, os elementos paratextuais que abririam a possibilidade de pensar algo como uma passagem ao sentido.
Hilda Machado e a poesia em movimentos nublados
Authors: Maia Terra de Faria Alessandra , Britto Paulo Henriques
Published: May 2022

O presente artigo analisa o poema “Cabo Frio” do premiado livro póstumo Nuvens, de Hilda Machado. Sua imagética é escrutinada segundo três ênfases distintas: a primeira, na relação paisagem-natureza em sua poesia; a segunda, na relação entre a espacialização dos sentimentos e a fluidez de um objeto fundamental — a nuvem — que nela se expõem; e a terceira, na relação entre a representação da própria figura da mulher no teatro grego, na poesia e na atualidade. No sentido de contextualizar o poema em relação ao conjunto da obra da poeta, serão tecidos comentários relacionando-o com passagens de alguns dos demais poemas. O artigo apresenta como resultado alusões implícitas à política, à situação da mulher e à rivalidade dos poetas, e suas interseções na filosofia, política e teatro, a partir da obra analisada.
A resposta de Fabio Durão à crise da teoria literária em Metodologia de pesquisa em literatura
Authors: Rocha Pinezi Gabriel Victor
Published: May 2022

Em seu mais recente livro, Fábio Ackcelrud Durão parte da premissa de que a pesquisa em letras no Brasil é indissociável do aparato institucional e político que a legitima, propondo assim uma investigação crítica das práticas de pesquisa da universidade brasileira. Para o autor, a sobrevivência dos estudos literários à atual crise institucional depende de metodologias de pesquisa e práticas capazes de desacelerar o produtivismo acadêmico, possibilitando um debate mais sólido e de maior impacto entre os pares. Isso seria possível a partir da delimitação de um certo campo de objetividade comum, no qual a interpretação de textos e o close reading sejam privilegiados em detrimento de interpretações normativas. Nesta resenha, discuto os argumentos de Durão, questionando a hipótese de que uma melhor regulação do campo se daria pelo estabelecimento de um objeto comum. A partir de uma comparação entre as metodologias das ciências empíricas e as dos estudos literários, proponho que o problema no Brasil não é tanto a falta de uma compreensão comum de seu objeto (isto é, a literatura), mas mais um uso não-científico da teoria. Defendo, portanto, que os pesquisadores de literatura tenham como horizonte o falseamento das premissas teóricas aceitas pela comunidade, tal como no campo das ciências experimentais, e não simplesmente a aplicação de diferentes teorias com vistas à interpretação textual.
Paradoxos e promessas da natureza-morta em poesia: notas de leitura sobre Lu Menezes e Suzanne Doppelt
Authors: Glenadel Paula
Published: May 2022

O gênero pictórico chamado de “natureza-morta” está envolvido por uma ambivalência fundamental, que se manifesta em diferentes níveis. Neste artigo, proponho abordar a ambivalência do gênero em dois desses níveis, que me parecem ser os mais importantes e os mais produtivos em termos de um pensamento poético sobre a relação entre homem, linguagem e mundo. O primeiro é o nível da história das transformações das formas artísticas; o segundo é o nível de uma filosofia da imagem em sua oscilação entre uma pulsão que se poderia chamar de ritmo-plástica e uma pulsão representativa. Modulando essas ambivalências, a apropriação da natureza-morta em poesia (poemas que se referem a cenas de natureza-morta ou que interpretam com meios verbais o universo pictórico característico da natureza-morta) permite pensar a potência e os limites da arte em relação à experiência. É o que se procurará demonstrar através da leitura de textos poéticos de Lu Menezes e de Suzanne Doppelt.
Discutindo níveis de generalização na gramática de construções baseada no uso: a rede construcional [(x) chegar sn]foc no PB
Authors: De Freitas Junior Roberto , Da Silva Nascimento João Paulo , Mouta Marques Priscilla , Gonçalves Albernaz Isabela Maria
Published: May 2022

RESUMO: O artigo apresenta um estudo sobre a rede taxonômica [(X) CHEGAR SN]FOC no Português do Brasil (PB) e as relações de herança mantidas entre o esquema [(X)VSN]FOC, o subesquema [(X) CHEGAR SN]FOC e microconstruções [(X) CHEGAR SN]FOC com propriedades próprias de forma e sentido. O trabalho se desenvolve a partir do modelo da Gramática de Construções Baseada no Uso (GCBU), associado à Linguística Cognitivo-Funcional, que defende a emergência da gramática como processo resultante da experiência com o uso da língua e da atuação dos Processos Cognitivos de Domínio Geral.  Argumentamos a favor de uma representação em rede de microconstruções [(X) CHEGAR SN]FOC - de sentido apresentacional de tempo, evento e referentes inespecíficos -, ligadas ao esquema [(X) CHEGAR SN]FOC  - de sentido introdutório/apresentacional -, por sua vez, ligado ao padrão mais abstrato [(X)VSN]FOC - de natureza pragmática fortemente associada à informatividade, em particular à focalização. Assim, o artigo discute limites e possibilidades para a representação cognitiva da gramática, em uma perspectiva bottom-up de aquisição da linguagem, pautando-se no compromisso com o realismo psicológico e os limites da categorização. Ainda, a discussão tangencia os pressupostos apresentados em Perek (2015) acerca da hipótese da valência verbal baseada no uso e da emergência de novas representações de maior grau de emancipação e acessibilidade cognitiva.

Este artigo discute o trabalho feminino agrícola e não agrícola no estado do Rio Grande do Sul. Foram entrevistadas mulheres que trabalham com a produção de leite (atividade agrícola) e mulheres que trabalham em agroindústrias como assalariadas e com atividades autônomas (atividades não agrícolas). Os resultados apontam dinâmicas distintas de trabalho, gestão da atividade e renda das mulheres, conforme cada grupo. O trabalho não agrícola é visto por elas como autonomia, enquanto para as mulheres a produção agrícola é uma tradição na propriedade. O gerenciamento da atividade e da renda é, majoritariamente, feito pelas mulheres e seu cônjuge nas atividades agrícolas e, nas não agrícolas, somente pela mulher.

Authors:   National Council for Scientific Research, P.O.Box 118281, Beirut, Lebanon Faculty of Science, Lebanese University, Hadath, Lebanon, Ramadan-Jaradi Ghassan
Published: May 2022

The study of marine birds in the northern part of Lebanon recorded 2681 individuals, distributed over 86 species. Among them 35 are foreshore species, 18 coastal, 6 maritime, 9 ducks, 6 herons, 9 various saltwater related species and 3 terrestrial. The highest density is shown by the yellow-legged Gull Larus michahellis and common blackheaded gull Chroicocephalus ridibundus. The globally vulnerable yelkouan shearwater Puffinus yelkouan, an endemic species to the Mediterranean, appears on the 9th rank in the classification of seabird species from the more to the least abundant, highlighting as such, beside other 6 globally near threatened species, the role that Lebanon can play in improving the conservation status of these species. Regarding the phenological status of species, 48 are passage migrant/winter visitors, 31 passage migrants, 5 winter visitors and 2 vagrant species. The surveys revealed that three coastal seabird species (Armenian gull Larus armenicus, slender-billed gull Chroicocephalus genei and sandwich tern Thalasseus sandvicensis) and one ubiquist species (Eurasian Golden Plover Pluvialis apricaria) are not rare as it was believed in previous papers but fairly common winter visitors. The study identified the yellow-legged gull breeding population to be 160 couples, and confirmed the second and third breeding records of the little ringed plover Charadrius dubius.

Insects often intervene in the process of dieback, either as a primary factor triggering the phenomenon or as a secondary factor accentuating and amplifying the process over time. Among the listed insects, xylophages, particularly Scolytidae, Cerambycidae and Buprestidae, which appear to play an important role in the cypress dieback in the studied area. These xylophages are predominantly composed of palaearctic dominant species. Four species caused most of the damage inflicted on Cypress: Scolytus sp, Pityokteins curvidens, Pissodes sp and Anthaxia sp.

Even one can make a difference — Female board representation and capital structure: Evidence from Taiwan
Authors: Chen Chia-Wei , Yi Bingsheng , Zhao Meng , Zheng Qiancheng
Published: May 2022

This paper investigates whether and how female board representation will affect firms’ capital structure using a sample of 16,477 firm-year observations during the period from 2006 to 2017 obtained from Taiwan Economic Journal (TEJ). While 67% of Taiwanese firms have female directors, most firms have only one female director. We find that firms with female directors use more debt financing, particularly, more short-term debt. Our results support the notion that female board representation is associated with increased monitoring through increased use of debt, particularly short-term debt. Our results remain consistent with various robustness tests using alternative samples, measures, and methodologies.
Intra and inter-observer reliability and agreement on defining tachypnea in infants: A methodological comparison
Authors: Ihyauddin Zulfikar , Putri Dwi Astuti Dharma , Kejora Elsa , Oktaria Vicka
Published: May 2022

Background: Measurement of respiratory rates (RR) in children
often showed disagreement. We aimed to determine the reliability of RR
measurement within and between observer(s) (intra- and inter-observers
agreement), and to compare the reliability of different methods of RR
measurement (visual versus using stethoscopes). Methods: Two
observers performed RR measurements in infants whom reported to have
Acute Respiratory Infections (ARI), by visual method and with
stethoscope during home visit. Intra- and inter-observers and between
method agreements were determined using Pearson correlation test and
Bland-Altman plot. Kappa test was used to measure agreements in defining
tachypnea. Results: During the study, there were 196 visits
from 130 participants documented. The Pearson’s rho correlations were
above 0.80 for all measurements. RR measurement with a stethoscope
demonstrated a higher mean of 1.39 breaths per minute in observer 1
(limits of agreement -12.55 to 9.78) and 1.39 breaths per minute in
observer 2 (limit of agreement -11.97 to 9.18), compared to the visual
method. For tachypnea, the Kappa-agreements for intra-observer using
visual count were 0.68 and 0.72, while for auscultation were 0.59 and
0.79, for observer 1 and 2, respectively. Inter-observer kappa
agreements were 0.78 (visual count) and 0.79 (auscultation), while the
between-method kappa agreement were 0.64 and 0.73. Conclusion:
Although good agreements were obtained, the limits of agreements for all
parameters were wide. When restricted to determine tachypnea, all
agreements were weakened. This finding emphasises the need to review the
current method in determining tachypnea to minimise under and over
diagnosis of pneumonia in children. Keywords: respiratory rate;

Inspiratory muscle training in children and adolescents with neuromuscular disorders: a cross-over randomized controlled trial
Authors: Human Anri , Corten Lieselotte , Lozano-Ray Eleonora , Morrow Brenda
Published: May 2022

Progressive respiratory muscle weakness and ineffective cough
contributes to morbidity and mortality in children with neuromuscular
disorders (NMD). Inspiratory muscle training (IMT) aims to preserve or
improve respiratory muscle strength and reduce respiratory morbidity.
This study intended to determine the safety and efficacy of IMT in
children with NMD. A randomized cross-over study compared three-month
intervention (IMT) with control periods (no IMT). Children diagnosed
with NMD (5-18 years) performed 30 breaths (at 30% of inspiratory
muscle strength (Pimax)) with an electronic threshold device, twice
daily. During the control period participants did not perform any IMT.
Twenty-three children (median (IQR) age of 12.33 (10.03-14.17) years),
mostly male (n=20) and non-ambulant (n=14) participated. No adverse
events related to IMT were reported. No difference in median patient
hospitalization and respiratory tract infection rates between control
and intervention periods (p=0.60; p=0.21) was found. During IMT, Pimax
and peak cough flow improved with a mean (SD) of 14.57 (±15.67) cmH
O and 32.27 (±36.60) L/min, compared to 3.04(±11.93)cmH
O (p=0.01) and -16.59 (±48.29) L/min (p = 0.0005)
during the control period. Spirometry, functional ability and total
health-related quality of life scores following intervention did not
show a significant change. Patient satisfaction with IMT was high
(median 8/10 (IQR 5-10)) and adherence was good. A three-month IMT
programme in children with NMD appears safe and well-tolerated, with
significant improvement in respiratory muscle strength and cough
efficacy. The use of IMT could be considered as an adjunct to
respiratory management in children with NMD.

Published: May 2022

Introduction/Objective. Dry eye is a multifactorial disease with incidence up to 50% in the general population. It is characterized by a loss of homeostasis of the tear film and accompanied by ocular symptoms. Ocular Surface Disease Index (OSDI) questionnaire is designed to provide a rapid assessment of the symptoms. The aim of this study was to evaluate the diagnostic capacity of OSDI. Methods. A prospective, randomized and observational study was conducted at the Clinic for Eye Disease, University Clinical Center of Serbia, between December 2018 and February 2019. The OSDI questionnaire was used to rate the severity of dry eye disease. Schirmer I test, tear break-up time test (TBUT), Rose Bengal test and lid-parallel conjunctival folds (LIPCOF) test were performed as a clinical proof of the symptoms. Results. A total of 27 patients, 15 male (55.4%) and 12 female (44.6%), with mean age of 60 ? 15 years were included in the study. The average value of OSDI score was 26.37 ? 23.98 (0?80). Schirmer I test and Rose Bengal test for the right and the left eye, as well as the TBUT test for the left eye were positively correlated with OSDI score (Spearman correlation coefficient). Conclusion. OSDI questionnaire is a fast, reliable, and inexpensive test. In our study we have found a correlation between the OSDI score and other clinical tests, except with LIPCOF test. At this moment, the questionnaire that could be the gold standard for dry eye disease diagnosis does not exist, therefore further studies concerning this topic are needed.

Published: May 2022

OBJECTIVE

Diabetes among individuals with low BMI (<19 kg/m2) has been recognized for >60 years as a prevalent entity in low- and middle-income countries (LMICs) and was formally classified as “malnutrition-related diabetes mellitus” by the World Health Organization (WHO) in 1985. Since the WHO withdrew this category in 1999, our objective was to define the metabolic characteristics of these individuals to establish that this is a distinct form of diabetes.

RESEARCH DESIGN AND METHODS

State-of-the-art metabolic studies were used to characterize Indian individuals with “low BMI diabetes” (LD) in whom all known forms of diabetes were excluded by immunogenetic analysis. They were compared with demographically matched groups: a group with type 1 diabetes (T1D), a group with type 2 diabetes (T2D), and a group without diabetes. Insulin secretion was assessed by C-peptide deconvolution. Hepatic and peripheral insulin sensitivity were analyzed with stepped hyperinsulinemic-euglycemic pancreatic clamp studies. Hepatic and myocellular lipid contents were assessed with 1H-nuclear magnetic resonance spectroscopy.

RESULTS

The total insulin secretory response was lower in the LD group in comparison with the lean group without diabetes and the T2D group. Endogenous glucose production was significantly lower in the LD group than the T2D group (mean ± SEM 0.50 ± 0.1 vs. 0.84 ± 0.1 mg/kg · min, respectively; P < 0.05). Glucose uptake was significantly higher in the LD group in comparison with the T2D group (10.1 ± 0.7 vs. 4.2 ± 0.5 mg/kg · min; P < 0.001). Visceral adipose tissue and hepatocellular lipids were significantly lower in LD than in T2D.

CONCLUSIONS

These studies are the first to demonstrate that LD individuals in LMICs have a unique metabolic profile, suggesting that this is a distinct entity that warrants further investigation.

Acute adhesive intestinal obstruction is a complex and often unpredictable pathology. Therefore, the study of the pathomorphological component of this problem is important for the selection of adequate surgical and conservative therapy of the disease.The aim of the study is to research the pathomorphological changes in the peritoneum in patients with acute adhesive intestinal obstruction and determine the basic patterns of adhesions.Material and methods. The study covered 117 operated patients with various acute diseases of the peritoneal cavity of an inﬂ ammatory nature, which to varying degrees were accompanied by damage to the peritoneal mesothelium. Collection of material for morphological studies was performed according to standard requirements for the manufacture of histological specimens. Biopsies included areas of adhesive and peritoneal tissue.Results. Through the examination of peritoneal biopsy material in the event of local peritonitis was found that some mesotheliocytes developed pronounced dystrophic changes, in some cells with the transition to necrosis. The lumens of the vessels of the microcirculatory tract were moderately dilated, ﬁ lled with erythrocytes, and stasis developed in some of them. The main component of the inﬂ ammatory focus was the increase in catabolic processes that led to metabolic disorders in connective tissue, accumulation of breakdown products of fat and carbohydrate metabolism and the development of tissue acidosis.Summary. Adhesion disease is characterized by a great variety of pathomorphological picture, which is due to the phased development of inﬂ ammatory and hyperproliferative processes, and that is fundamental in the pathogenesis of adhesive disease.

Conducting densitometric studies aimed at objectifying and improving the accuracy of estimating the structural parameters of the bone become fundamental in the rehabilitation of patients to meet their functional, prosthetic and aesthetic needs. Today, the results of bone density analysis determine the priority in choosing a new method of direct implantation with immediate load or search for an alternative to existing ones that guarantee the predictability of the result concerning the physiological terms of osteogenesis, directed bone regeneration and other reconstructive surgical interventions. Based on 243 computed tomographic digital scans taken by the VaTech PaX-I 3D Green extraoral system, bone density was analyzed in conventional grayness units (CGU) in the projection of the missing 3.7, 3.6, 4.6, 4.7 teeth and 136 studies were selected as objects for this work, which provide proper information and signiﬁ cant cognitive importance. The maximum mineralization of bone tissue in the toothless distal areas of the lower jaw, both on the left and right sides, was established in individuals of the ﬁ rst study group (25-45 years) with values of pronounced density on sagittal sections of horizontal planes in the projection of 3.6 tooth M=1246.6±63.13 CGU and in projection 4.6 tooth, where M=1158.8±47.04 CGU. The lowest values of bone density were determined in individuals of the third study group (61-75 years) on sagittal sections of vertical planes in projections of 3.7 tooth, where M=736.8±42.63 CGU, and 4.7 tooth, where M=778.8±51.79 CGU. The result of the analysis of this work conﬁ rms the hypothesis of age-related dependence of changes in bone density on the time of tooth loss. It was found that early loss of the masticatory teeth leads to high indicators, with an increase in bone density towards distalization of the terminal defect of dentition. Conversely, the lack of functional action on bone tissue leads to a decrease in its density in the age aspect, and, accordingly, the exhaustion of the trabecular layer, which contributes to the progression of atrophic processes.

Influence of frequency and power control modes on the technical condition of hydraulic units of hydroelectric power plants
Authors: Baikov V. N. , Volkov A. V.
Published: May 2022

The features of the operation of hydroelectric power plants, which are used to regulate the frequency and power in the power system with a wide range of load variations and with varying degrees of intensity of operation mode variations, are considered. An approach is proposed to assess the impact on the reliability of hydraulic turbine equipment used in these modes. When examining the equipment of existing hydroelectric power plants, it has been revealed that the mode of automatic secondary regulation of frequency and power flows in the power system has the greatest impact on the technical condition of hydraulic turbines. Intense participation in regulation leads to an increase in dynamic loads on the hydraulic unit, loads on the friction pairs of the regulating elements of the turbine compared to the basic, semipeak and peak modes and leads to additional wear, reduced reliability and deterioration of the technical condition of the equipment. The operation in the automatic secondary regulation mode of hydraulic units at different HPPs differs depending on the function performed in the power system. To determine the loading of a hydraulic unit with transient load variation modes during operation in the mode of automatic secondary regulation of frequency and power flows, it is proposed to introduce a parameter characterizing the intensity of operation of hydraulic units of HPP in the aforesaid mode and to take it into account in order to accumulate data on the actual operating modes of hydraulic units and use it in assessing and predicting the technical condition of equipment.
Preheating of secondary superheated steam pipelines when starting steam turbines of SCР power units
Authors: Radin Yu. A.
Published: May 2022

Specific features of the technology of preheating hot legs of steam pipelines of intermediate steam overheating at the start-up of SCР power units with single-bypass thermal circuits are presented, with the advantages and disadvantages of various previously used methods of preheating steam pipelines after intermediate steam overheating at the startup of power units at supercritical pressure with a capacity of 250–300 MW considered. The analysis of the conditions for the completion of the heating of these steam pipelines using various process heating arrangements, as well as the heating steam consumption necessary for heating and its sources (special kindling steam by-passes, steam by-passes of own needs, kindling expander and combined heating technology at various intermediate rotational speeds of the turbine rotor) is carried out. The results of computational and experimental studies of the heating processes of steam pipelines during the start-up of SCР power units from various thermal states are presented, nomograms for determining the duration of preheating of mono and double steam pipelines with a capacity of 250–300 MW, developed on the basis of solving the inverse problem of thermal conductivity, are presented. The basis for determining the duration of heating of steam pipelines is the assumption of limited cooling of the medium pressure rotor of the steam turbine as steam is supplied to the same, as well as the temperature of the end section of the steam pipeline, which excludes the formation of condensate and thereby reduces the risk of its removal into the flow part when steam is supplied to the medium pressure cylinder. Two criteria for the termination of heating are determined in the form of an average integral temperature of the middle part of the steam pipeline and the temperature of its end section upstream the steam inlet elements of the medium pressure part.

This research is a development research (R & D). Informants from this study were English Language Tadris (TBI) students in the 5th semester of the 2019/2020 academic year, totaling 45 people. The informant selection technique is total sampling. The instrument used is a questionnaire to determine the analysis of student needs for the EPTIC writing test. The research procedure used is the ADDIE model, which is to analyze, design and develop an EPTIC writing test product based on Islamic values. Furthermore, to analyze the data, the researcher uses the theory of Miles and Huberman (1994) by reducing the data, presenting the data, and verifying the data and draw a conclusion. To validate the product, the researcher used a validation sheet from riduan theory (2007) which consisted of five categories, namely very valid, valid, less valid, invalid, and very invalid. The results showed that, 90.9% of students needed an EPTIC writing test based on Islamic values. After being validated by the validator, the EPTIC writing test based on Islamic values developed was very valid with a score of 93.13.
