Numerical Prediction and Reduction of Pressure Loss of Air Flow Inside a Sharp 90˚ Elbow Using Turning Vanes
Authors: Langwane Kahuma , Subaschandar N.
Published: July 2021

The aim of this study is to calculate the pressure loss and the effect of turning vanes on the pressure loss incurred by the flow in a duct with a 90˚ sharp elbow using numerical fluid mechanics. The main focus this study was to calculate the effects of the number of turning vanes and the length of the turning vanes on the pressure loss. Computational Fluid Dynamics calculations have been carried out using ANSYS Workbench software. Two turbulence models have been used in these calculations. They are the standard k- and the k- turbulence models. The number and length of the vanes were changed in the study to calculate their effects on pressure loss. The length of the vanes was varied from 0mm to 400mm in steps of 100mm on both sides of the bend and the number of vanes was changed from 0 to 3. It was found that a single curved turning vane can reduce the pressure loss significantly. The pressure loss does not reduce further when the length of the vanes was extended. As the number of turning vanes increased beyond one, the predicted pressure loss starts increasing. The turning vanes in duct systems can be used in industries and factories to reduce the pressure loss.

Authors: Umemoto Teruo , Yang Yuhao , Hammond Gerald B
Published: July 2021

This review deals with the historical development of all N-F fluorinating agents developed so far. The unique properties of fluorine make fluorinated organic compounds attractive in many research areas and therefore fluorinating agents are important. N-F agents have proven useful by virtue of their easy handling. This reagent class includes many types of N-F compounds: perfluoro-N-fluoropiperidine, N-fluoro-2-pyridone, N-fluoro-N-alkylarenesulfonamides, N-fluoropyridinium salts and derivatives, N-fluoroquinuclidium salts, N-fluoro-trifluoromethanesulfonimide, N-fluoro-sultams, N-fluoro-benzothiazole dioxides, N-fluoro-lactams, N-fluoro-o-benzenedisulfonimide, N-fluoro-benzenesulfonimide, 1-alkyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane salts, N-fluoropyridinium-2-sulfonate derivatives, 1-fluoro-4-hydroxy-1,4-diazoniabicyclo[2.2.2]octane salts, N-fluorodinitroimidazole, N-fluoro-trichloro-1,3,5-triazinium salt, N-F ethano-Tröger’s base derivatives, N-fluoro-methanesulfonimide, N-fluoro-N-arylarenesulfonamides, bisN-F salts such as N,N’-difluorobipyridinium salts and N,N’-difluoro-1,4-diazoniabicyclo[2.2.2]octane salts, and their many derivatives and analogs, including chiral N-F reagents such as optically active N-fluoro-sultam derivatives, N-fluoro-alkaloid derivatives, DABCO-based N-F derivatives, and N-F binaphthyldisulfonimides. The synthesis and reactions of these reagents are described chronologically and the review also discusses the relative fluorination power of each reagent and their mechanisms chronicling developments from a historical perspective.
DISTRIBUTION OF ETHEREUM BLOCKCHAIN ADDRESSES
Authors: Seitenov A. , Smagulova G.
Published: July 2021

Abstract: In the contemporary world, Ethereum is a very reliable financial saving among cryptocurrencies. It is also well known as a blockchain platform for creating and launching its own cryptocurrency. The applications run on Ethereum executed by a platform-specific cryptographic token, ether. During 2014, Ethereum had launched a pre-sale for ether, which had received an overwhelming response. Ether is used broadly for two purposes: it is traded as a digital currency exchange like other cryptocurrencies, and it is used inside Ethereum to run applications and even to monetize work. It should be noticed that the smart contract has brought a significant share of the success to Ethereum. The smart contract is a computer programme that independently performs assigned tasks between network participants without the participation of a third trusted party. Smart contracts and their intranet transactions have facilitated the rapid expansion of the Ethereum network. Smart contracts are widely represented on the market, either as electronic transaction payments or as applications for the implementation of logistics supplies, gambling, and other sectors. These transactions are irreversible and fully tracked online. Whereas the electronic records are available in a public distributed ledger and include data about user addresses, whereas the real names are hidden. The article explains the usage of decentralized accounts and their electronic transactions in the Ethereum network. The results are presented through different application sectors. Additionally, a new method for extracting blockchain records through node cluster via IPFS path is implemented in the research.

Authors: Stetsenko S , Sorokina L , Goiko A , Tsyfra T , Bolila N
Published: July 2021

Abstract: This paper considers the peculiarities of the formation of economic immunity of construction companies. A system has been proposed to improve the mechanisms of preventive protection and securement of enterprises from loss of viability and subsequent self-liquidation or bankruptcy, which allows effectively identifying existing risks and threats from micro-, meso- and macro-environments and responding to them with the preventive means through economic immunity. A new definition for the term «economic immunity» of the enterprise is proposed, which includes subsystems of monitoring, early detection of internal and external threats, assessment of the degree of danger (risks), diffusion, elimination or neutralization, and formation of «memory» of the threat through a system of indicators. The differences of economic indicators of construction enterprises, which are characterized by different levels of the anti-crisis potential use, are studied, the five most significant indicators of the use of the anti-crisis potential are identified. The rules-conditions for determining the level of activation of anti-crisis opportunities and vulnerability of enterprises to threats for economic security are formulated. Methods of identification and control of the level of anticrisis potential use of the construction enterprise in the context of digital transformation which allows estimating quality and expediency of administrative actions are developed.
The formation mechanism of the anti-crisis potential of the construction enterprise is developed. Its structure is defined, conceptual foundations of the integrated information system creation of the construction enterprise that should provide the possibility of interaction of various subsystems within the enterprise and the analysis of threats from interaction with various stakeholders are substantiated.

Such patterns allowed the authors to identify bottlenecks in the application of agile project management methodologies in the context of the development of innovative products of innovation systems.
Statistical analysis of random walks on network
Authors: Kalikova A.
Published: July 2021

This paper describes an investigation of analytical formulas for parameters in random walks. Random walks are used to model situations in which an object moves in a sequence of steps in randomly chosen directions. Given a graph and a starting point, we select a neighbor of it at random, and move to this neighbor; then we select a neighbor of this point at random, and move to it etc. It is a fundamental dynamic process that arise in many models in mathematics, physics, informatics and can be used to model random processes inherent to many important applications. Different aspects of the theory of random walks on graphs are surveyed. In particular, estimates on the important parameters of hitting time, commute time, cover time are discussed in various works. In some papers, authors have derived an analytical expression for the distribution of the cover time for a random walk over an arbitrary graph that was tested for small values of n. However, this work will show the simplified analytical expressions for distribution of hitting time, commute time, cover time for bigger values of n. Moreover, this work will present the probability mass function and the cumulative distribution function for hitting time, commute time.

Published: July 2021

Proper research and analysis of mortality dynamics is essential to provide reliable economic information about any country. This paper deals with the historical comparative time series analysis of the mortality rate dynamics in the BRICS countries to determine their economic performances over the years. This article presents stochastic models based on autoregressive integrated moving average (ARIMA (p, d, q)) models of various orders with a view to identifying the optimal and comparative model for the crude death rate (CDR) in the BRICS countries. The ARIMA (p, d, q) models were formulated for the crude death rates in the BRICS countries and the overall annual crude death rate for the period 1960–2018. The optimal choice of ARIMA models of order p and q was selected for each of the series. The results indicate that the ARIMA (2, 2, 0) model was the optimal model for predicting mortality dynamics in the overall BRICS data. In addition, there was a significant decrease in trends (p-value < 2.22e-16) during the study period from 1960 to 2018. In addition, the crude death rate’s data for the BRICS countries proved to be mostly non-linear, non-seasonal and without structural breaks. Finally, the findings of this study were discussed and recognized as having relevant policy implications for forecasting, insurance planning, as well as for disaster or risk reduction in the context of unprecedented global happenings in the post-pandemic era.

We present a method of selecting quasars up to redshift ≈6 with random forests, a supervised machine-learning method, applied to Pan-STARRS1 and WISE data. We find that, thanks to the increasing set of known quasars, we can assemble a training set that enables supervised machine-learning algorithms to become a competitive alternative to other methods up to this redshift. We present a candidate set for the redshift range 4.8–6.3, which includes the region around z = 5.5 where selecting quasars is difficult due to their photometric similarity to red and brown dwarfs. We demonstrate that, under our survey restrictions, we can reach a high completeness (66% ± 7% below redshift 5.6/

These observations are consistent with our predictions on efficiency. We argue that random forests can lead to higher completeness because our candidate set contains a number of objects that would be rejected by common color cuts, including one of the newly discovered redshift 5.7 quasars.

Published: July 2021

We present temperature maps of RS CVn star λ Andromedae, reconstructed from interferometric data acquired in 2010 and 2011 by the Michigan Infra-Red Combiner instrument at the Center for High Angular Resolution Astronomy Array. To constrain the stellar parameters required for this imaging task, we first modeled the star using our GPU-accelerated code SImulation and Modeling Tool for Optical Interferometry. The stellar surface was then imaged using our open source interferometric imaging code ROTational Image Reconstruction, in the process further refining the estimation of stellar parameters. We report that the measured angular diameter is 2.742 ± 0.010 mas with a limb-darkening coefficient of 0.231 ± 0.024. While our images are consistent with those of prior works, we provide updated physical parameters for λ Andromedae (R

Can Stochastic Resonance Explain Recurrence of Grand Minima?
Authors: Albert Carlo , Ferriz-Mas Antonio , Gaia Filippo , Ulzega Simone
Published: July 2021

The amplitude of the 11 yr solar cycle is well known to be subject to long-term modulation, including sustained periods of very low activity known as Grand Minima. Stable long-period cycles found in proxies of solar activity have given new momentum to the debate about a possible influence of the tiny planetary tidal forcing. Here, we study the solar cycle by means of a simple zero-dimensional dynamo model, which includes a delay caused by meridional circulation as well as a quenching of the α-effect at toroidal magnetic fields exceeding an upper threshold. Fitting this model to the sunspot record, we find a set of parameters close to the bifurcation point at which two stable oscillatory modes emerge. One mode is a limit cycle resembling normal solar activity including a characteristic kink in the decaying limb of the cycle. The other mode is a weak sub-threshold cycle that could be interpreted as Grand Minimum activity. Adding noise to the model, we show that it exhibits Stochastic Resonance, which means that a weak external modulation can toss the dynamo back and forth between these two modes, whereby the periodicities of the modulation get strongly amplified.
A new species and new recorded species of Orbiniidae Hartman, 1942 (Annedia: Polychaeta) from China
Authors: Sun Yue , Yu Lei , Li Xinzheng
Published: July 2021

A new species of the orbiniid genus Phylo, P. heterochaetus sp. n., is described based on material collected from northern Yellow Sea, China. This is the thirteenth species in Phylo Kinberg, 1866. The new species can be easily identified by the combination of the following characters: anterior thorax with 13 setigers, interramal cirri absent, anterior thoracic neuropodia with 4–5 rows of uncini, intermixed with few subuluncini in the first 1–2 rows, ventral fringe of numerous of stomach papillae present on setigers 12–24. We also described and illustrated P. fimbriata, which is recorded for the first time from China seas.

Authors: Liu Yingxun , Pu Yingting , Wang Xuming , Wang Xin , Liao Rui , Tang Keyi , Shunde Chen , Yue Bisong , Shaoying Liu
Published: July 2021

The missing-toothed pygmy weasel, Mustela aistoodonnivalis Wu and Kao, 1991, was originally described from Zhouzhi and Zhashui in the Qingling Mountains in Shaanxi province, China. Subsequently it was considered a subspecies of M. nivalis. During a faunal survey of northwest Sichuan, some specimens of M. aistoodonnivalis were collected. Molecular phylogenetic studies showed that M. aistoodonnivalis formed a distinct clade that was sister to M. eriminea based on one mitochondrial gene and six nuclear genes. Morphologically, there was an obvious difference between M. aistoodonnivalis and M. nivalis, especially the lack of the second lower molar. Geometric morphology studies and species delimitation analysis revealed the valid species status of M. aistoodonnivalis. In summary, we confirm that M. aistoodonnivalis is an independent species rather than a subspecies of M. nivalis, and that it is more closely related to Mustela eriminea.

Habitat mapping is nеcessary for the efficient conservation and protection of marine ecosystems. In addition, it is a requirement for EU Member States as stated in the European Union (EU) Habitats Directive (92/43/EEC), as well as necessary for the achievement and maintenance of 'good environmental status (GES)' of benthic marine habitats in the framework of the EU Marine Strategy Framework Directive (2008/56/EC).

This study provides baseline information on the marine benthic habitats of Sozopol Bay (Black Sea) and Karpathos and Saria islands (Mediterranean Sea). These two Natura 2000 sites were selected as study sites of the RECONNECT project, which aimed at creating a transnational cooperative network to confront the environmental threats of ecosystems with a high natural and cultural interest, by the establishment of common practices and a joint regional strategy. The specific objective was to map the marine habitats using a defined a priori classification (EUNIS), with the ultimate purpose of supporting government marine spatial planning, management and decision-making processes through the development of a Decision Support System.
Preparing Nurses for Roles in Telehealth: Now is the Time!
Authors: Rutledge Carolyn , Gustin Tina
Published: July 2021

With the COVID-19 pandemic, the method for delivering healthcare changed overnight. Telehealth became a primary method of delivering care. Suddenly, nurses were expected to utilize technology with very little, if any, training in telehealth. All evidence suggests that telehealth is here to stay. As such, it is now time for healthcare providers to reflect on best practices for telehealth, and for nurse educators to ensure that graduates are prepared to function in the new telehealth arena. This article provides an introductory overview of the history of telehealth nursing; uses for telehealth with the COVID-19 pandemic; new awareness of telehealth challenges, and nursing roles. We also discuss sites that require a telehealth nurse and the Four P’s framework for telehealth education.
Social Upheaval and a Dean’s Vision for Professional Nursing: The Work of Dorothy M. Smith
Authors: Curry Kim
Published: July 2021

Dorothy Mary Smith (1913–1997) was a visionary leader and innovator in nursing education. She was the founding dean of the University of Florida College of Nursing and played a key role in the design of an early academic medical center model. This article will discuss her education and early years, and the formation of Smith’s perspective on nursing education, exemplified by the implementation of her unification model of nursing, which was later adopted by numerous other academic nursing programs. During her deanship, significant events included the intrusion of the Johns Committee, an offshoot of the McCarthy investigations. The changing tides and times, such as the civil rights movement, also brought controversy and struggle to southern universities. In the end, financial downturns in state funding brought an end to the vision of Smith and her colleagues, leading her to ponder the outcome “if I had stayed.” Smith was an innovative leader whose legacy inspired graduates and faculty long after her academic career ended.
Smooth augmented Lagrangian method for twin bounded support vector machine
Authors: Bazikar Fatemeh , Ketabchi Saeed , Moosaei Hossein
Published: July 2021

In this paper, we propose a method for solving the twin bounded support vector machine (TBSVM) for the binary classification. To do so, we use the augmented Lagrangian (AL) optimization method and smoothing technique, to obtain new unconstrained smooth minimization problems for TBSVM classifiers. At first, the augmented Lagrangian method is recruited to convert TBSVM into unconstrained minimization programming problems called as AL-TBSVM. We attempt to solve the primal programming problems of AL-TBSVM by converting them into smooth unconstrained minimization problems. Then, the smooth reformulations of AL-TBSVM, which we called AL-STBSVM, are solved by the well-known Newton's algorithm. Finally, experimental results on artificial and several University of California Irvine (UCI) benchmark data sets are provided along with the statistical analysis to show the superior performance of our method in terms of classification accuracy and learning speed.
“La cocina de la esclava y la fama para su ama”. Intercambios rituales y paradojas de la esclavitud en Tetuán
Authors: Mateo Dieste Josep Lluís
Published: July 2021

En algunas situaciones de desigualdad los grupos dominantes establecen intercambios y obligaciones clientelares con los grupos subalternos y les atribuyen contrapoderes y amenazas diversas para el orden social. En este artículo desarrollaré esta hipótesis a partir de un estudio de las domésticas de origen esclavo en Tetuán (Marruecos), desde finales del siglo XIX hasta la primera mitad del XX, y su relación con las familias de medio y alto rango para las que trabajaban, a partir de fuentes orales y de archivo. Sujetas a una situación de dominación, aquellas mujeres devinieron representantes del prestigio del grupo propietario a través de sus labores gastronómicas, como signo de distinción. Y muchas de ellas ejercieron funciones de curación y protección, como mediadoras con santuarios y entidades no humanas o vinculadas a cofradías como los gnawa. De hecho, todos estos procesos de intercambio se generaban y transformaban a través de mecanismos y escenarios rituales. Y en estos procesos simbólicos, los cuerpos de esclavos y libertos devinieron agentes de aquellas relaciones clientelares, en los que se proyectaban paradójicos poderes tanto para provocar el mal como para protegerse de él.
La ciudad en bicicleta. Ocupación del espacio público e higienización social en Mérida, México
Authors: Lisbona Guillén Miguel , Sánchez Martín Ricardo
Published: July 2021

Como ha ocurrido en otras ciudades del mundo, en Mérida (México) miembros de la sociedad civil han impulsado el uso de la bicicleta como forma de ocupación del espacio público a través de un recorrido semanal nocturno. Hacer más apto tal espacio para los habitantes, alejados del uso del vehículo, también ha propiciado distintas iniciativas políticas, incluso con la colaboración entre el grupo denominado CicloTurixes, promotor de los paseos semanales y del uso de la bicicleta, e instancias de la administración pública, tanto del gobierno estatal de Yucatán como del municipal. Tales acciones han tendido a la higienización social del espacio público; es decir, su ocupación por parte de la ciudadanía, deseada por el grupo de ciclistas, no contradice de manera radical las políticas públicas de control de tal espacio en Mérida.

Cet article prend acte de nouvelles pratiques et de nouveaux usages liés aux réseaux sociaux numériques, alors que se développe la figure de l’influenceur. Nombre de plateformes adoptent une définition de l’engagement relativement éloignée de celle forgée en Sciences de l’Information et de la Communication (SIC), au travers du paradigme de la communication engageante, voire, de façon plus récente, de la communication numérique engageante. Il s’agit donc de décrire certaines innovations tout en les situant par rapport à la proposition robuste qu’est celle forgée en SIC. Se présente alors un fort enjeu d’interdisciplinarité et des questions de traduction ou de significations sont posées voire problématisées.

The pandemic, which is brought about by the SARS CoV-2 infection, has inundated the entire world and obliterated the economies of numerous nations. Hence, looking for treatment and prophylaxis of COVID-19, Quercetin, which is a flavonoid gotten from plants and different sources like grapes, onion, tomatoes, apple, and so forth and has various properties like calming property, cardioprotective, and neuroprotective properties, is inspected for its antiviral properties, so it tends to be considered as one of the adjuvant medicines alongside the pharmacological medicines like Remdesivir and plasma treatment. A survey of the antiviral property of Quercetin from distributed articles proposes that Quercetin has a solid antiviral movement towards SARS C0V-2 and other upper respiratory tract infections. It can be securely and financially used to battle COVID-19. For high-hazard populaces, this medication can be a brilliant decision of treatment. Here the authors give proof to the utilization of Quercetin in relationship with pharmacological treatments like Remdesivir or improving plasma treatment.

Published: July 2021

Sri Lanka is one of the global biodiversity hotspots that contain a large variety of fauna and flora. But nowadays Sri Lankan wildlife has faced many issues because of poor management and policies to protect wildlife. The lack of technical and research support leads many researchers to retreat to select wildlife as their domain of study. This study demonstrates a novel approach to data mining to find hidden keywords and automated labeling for past research work in this area. Then use those results to predict the trending topics of researches in the field of biodiversity. To model topics and extract the main keywords, the authors used the latent dirichlet allocation (LDA) algorithms. Using the topic modeling performance, an ontology model was also developed to describe the relationships between each keyword. They classified the research papers using the artificial neural network (ANN) using ontology instances to predict the future gaps for wildlife research papers. The automatic classification and labeling will lead many researchers to find their desired research papers accurately and quickly.

Benjamin Franklin foi um pensador americano que se tornou figura emblemática do imaginário estadunidense. Neste artigo, apresentam-se suas contribuições relativas à educação do corpo. Para se alcançar o intento, realizou-se uma pesquisa, tendo-se como fontes os escritos de Franklin que abordaram prescrições em relação à dieta e exercícios físicos. Demonstrou-se, pela análise das fontes, que uma moral de cunho religioso moldou os cuidados do corpo, apresentando elementos de quantificação, individualização, treinamento e moderação dos hábitos, com ênfase no papel da natação como atividade útil e saudável. Concluiu-se que uma moral protestante influenciou a visão de Franklin em relação à educação do corpo, por meio do utilitarismo vinculado ao ascetismo como estilo de vida.

Authors: Castellanos Samuel Luis Velázquez , Oliveira Wilson Raimundo de
Published: July 2021

Aborda-se o conjunto de práticas e representações culturais do Colégio Universitário da Universidade Federal do Maranhão (1980 a 1995), e a materialização da cultura escolar democrática via práticas escolares. Avaliam-se práticas educativas, pedagógicas e culturais que transformadas em rituais escolares denunciam a gramática escolar e sua identidade como Colégio de Aplicação. Utilizam-se pressupostos teórico-metodológicos da história cultural para cruzar dados extraídos de jornais, dispositivos legais, arquivo escolar e entrevistas. Concluiu-se que a integração política entre modos de conhecimento e exercício do poder mediada por táticas de apropriação na busca do sucesso escolar aponta o COLUN como instrumento de inserção/ascensão social num processo de emancipação contínua via educação
Fundamentação da história da educação brasileira
Authors: Briskievicz Danilo Arnaldo
Published: July 2021

O objetivo deste estudo é proporcionar o alargamento da concepção de narrativa histórica educacional, nesse caso, do Brasil Colônia, especialmente na transição entre os séculos XVII e XVIII em torno do conceito de gesto pedagógico colonial. Descrevemos este conceito e propomos sua confrontação com a realidade histórica da formação do território brasileiro, especificamente em torno do território mineiro, nas minas do Serro do Frio (Vila do Príncipe, capital da Comarca do Serro do Frio atual cidade do Serro/MG). Para isso, introduzimos a noção de documento como processos para consulta escritos em sagradas letras a fim de dizer os ausentes, responsável pela condução dos procedimentos de controle da Coroa portuguesa de seu reino e de suas colônias, a partir de alguns argumentos de António Manuel Hespanha, em especial dos Regimentos. A metodologia circunscreve-se em torno de pesquisa bibliográfica de documentos arquivísticos portugueses e brasileiros, bem como o diálogo de pensamento com historiadores. O resultado alcançado é a oferta de fundamentação para a narrativa histórica educacional, em especial, para a revelação do papel da educação – formal ou informal – na leitura e escrita da história colonial brasileira.

Authors: Cassani Juliana Martins , Carvalho Lucas Oliveira Rodrigues de , Ferreira Neto Amarílio
Published: July 2021

A pesquisa analisa os dispositivos utilizados pela imprensa periódica de ensino e de técnicas para constituir projetos formativos para a Educação Física fundamentados nas especificidades culturais latino-americanas. Possui como fonte a Revista Brasileira de Educação Física (1944-1952) e utiliza como pressuposto teórico-metodológico o conceito de análise pela materialidade. As fontes acenam para as estratégias editoriais que ampliaram a circulação do periódico internacionalmente, materializando-o como espaço de intercâmbio entre os articulistas dedicados às problemáticas do campo da atuação profissional. A publicação de orientações didáticas, divulgações de Congressos, cursos de formação e oferta de bolsas de estudos consolidou a campanha de cooperação entre o Brasil e os países vizinhos.
El curriculum “Maestros de Enseñanza Básica”
Authors: Mendez Jorgelina
Published: July 2021

Este artículo se inscribe en el marco de una investigación más amplia, analizando una reforma de formación docente -el curriculum Maestros de Enseñanza Básica- implementada en la transición democrática argentina (1983-1989) en la cual entran en diálogo la agenda educativa nacional y global a través de los organismos internacionales. La reconstrucción de la experiencia se fundamenta en el análisis documental (oficiales y de organismos internacionales) y de normativa relacionada a ella así como entrevistas a actores que participaron en su definición y trabajos académicos de sus protagonistas. Se observó que esta política articuló la aspiración del gobierno por democratizar las instituciones y las relaciones pedagógicas en oposición al autoritarismo vivido en la dictadura militar con los discursos internacionales que pugnaban por la jerarquización y profesionalización de la formación y práctica docente. Asimismo, adelantó cuestiones en relación con la duración y estructura del curriculum así como la organización de la práctica docente que estarán presentes hasta hoy en las discusiones sobre la formación. No obstante, lo breve de la experiencia (1987-1990) y las formas de implementación de la reforma impidieron que la misma sea recuperada como antecedente de esas discusiones.
A atuação dos poderes executivo e legislativo na expansão dos ginásios e colégios estaduais no estado de São Paulo (1963-1971)
Authors: Diniz Carlos Alberto
Published: July 2021

Este artigo discute a participação dos Poderes Executivo e Legislativo na expansão dos ginásios e colégios públicos estaduais no Estado de São Paulo entre 31 de janeiro de 1963 e 15 de março de 1971, período em que foram criadas aproximadamente 1.106 escolas de ensino médio. Para melhor compreensão da atuação dos deputados estaduais e dos governadores, recorremos ao arcabouço teórico da Nova História Política, além do trabalho de Pierre Bourdieu sobre a noção de campo. Mesmo com a ditadura militar, a expansão do ensino secundário público no Estado de São Paulo, capitaneada sobretudo pelo Poder Executivo, se manteve em ritmo acelerado a exemplo do que ocorreu no período de redemocratização (1945-1964).
História da educação da população negra no Brasil e a produção discente sobre educação e relações étnicorraciais (2003-2014)
Authors: Carvalho Marcelo Pagliosa
Published: July 2021

A categoria ‘História da Educação da População Negra’ da pesquisa Educação e relações étnico-raciais: o estado da arte (Silva, Regis, & Miranda, 2018) abrangeu a análise de teses e dissertações defendidas em programas de pós-graduação stricto sensu em educação entre 2003 e 2014. Neste artigo, examinaram-se os 18 trabalhos discentes que foram agrupados em três subcategorias. Realizou-se uma análise de conteúdo dos trabalhos, uma breve descrição dos dados estatísticos, temáticas em destaque, metodologias, recomendações e referenciais teóricos mais utilizados. Discutiram-se suas contribuições para o campo da história da educação. Sublinhou-se que o conjunto das pesquisas tem o mérito de debater histórias, memórias, lutas e trajetórias de vidas silenciadas na ciência brasileira.

Sleep Bruxism
Authors: Vasundhara V.
Published: July 2021

Activities of the masticatory system can be divided into functional, which includes chewing and speaking, as well as parafunctional, which includes clenching or grinding of the teeth. Sleep bruxism (SB) is the abnormal, nonfunctional contact of the teeth and if ignored leads to the breakdown of dentition and orofacial pain. Hence, early diagnosis and treatment are considered to be of utmost importance. SB has multifactorial causes that have to be identified and managed by various treatment modalities. As bruxism events bring about tooth and restoration damage, it is of major concern for the dentists.
Anterior esthetic rehabilitation using a casted palatal loop connector
Authors: Mukhopadhyay Pronoy , Khalikar Arun , Wankhade Sattyam , Deogade Suryakant
Published: July 2021

This article aims to demonstrate an esthetic rehabilitation of the anterior teeth region with increased prosthetic space with a fixed prosthesis without compromising esthetic proportions. In cases where excess pontic space is present, the use of a conventional prosthesis would jeopardize the esthetic proportions to maintain the integrity of the prosthesis. A loop connector, which is usually a spring cantilever connector system, can be advocated in such cases to re-establish form without obliterating preexisting spaces or diastema. This case report demonstrates prosthetic rehabilitation of a missing anterior tooth in a 37-year-old female patient with an increased pontic space using a loop connector system that takes bilateral support to better support the prosthesis functionally from the abutments and the palatal tissues that it is rested upon in close adaptation with. In situations that pose constraints in placing an isolated implant-supported prosthesis, a loop connector fixed prosthesis is warranted, to maintain spaces around the pontic that would not compromise with the esthetics and even mechanically sustain well.
A case of primary and secondary syphilis presenting together as immune reconstitution inflammatory syndrome

Published: July 2021

Immune reconstitution inflammatory syndrome (IRIS) is a condition during the clinical course of HIV infection in which there is paradoxical worsening and/or new onset of opportunistic infections in a HIV-positive patient who has recently been started on anti-retroviral therapy (ART). We present a case of AIDS with CD4 count of 20 cells/μl who presented within 6 weeks of starting ART with a CD4 count of 160 cells/μl and a painless solitary genital ulcer along with annular dark-colored plaques over soles. His screening test for syphilis was negative both during baseline evaluation, prior to initiation of ART, and during his clinical presentation. His disease was confirmed based on a positive treponema pallidum hemagglutination test report and a suggestive skin biopsy. He responded well to three doses of Benzathine Penicillin and continuation of ART. There are very few case reports of syphilis presenting as IRIS and this case is all the more unique as he had features of both primary and secondary syphilis occurring together within 6 weeks of starting ART. This report would reiterate the fact that syphilis and HIV co-infection can alter the natural course of both the diseases and a high index of suspicion is required for treating them.
