O português do(a) surdo(a) no rizoma das línguas brasileiras
Authors: Lima Hildomar José , Rezende Tânia Ferreira 
Published: March 2020

A concepção de português brasileiro está vinculada à racionalidade cientifica eurocêntrica que mantém a geopolítica das línguas brasileiras com base no poder político da língua imperial, do colonizador e da colonização. Esse pensamento ocidental determina a importância política tanto da escrita sobre a oralidade quanto da língua oral falada por uma minoria de brasileiros(as) em relação ao português como língua de tantas outras comunidades linguísticas e estabelece uma lógica de organização hierárquica vertical das línguas brasileiras. Essa forma de estratificação política das línguas opera para a manutenção da colonialidade do poder, do saber e da linguagem sobre povos historicamente subalternizados. Com base nas noções de “árvore-raiz” e de “raiz-fasciculada” (DELEUZE; GUATTARI, 2011), busca-se refletir sobre a construção ideológica do monolinguismo brasileiro a partir de posturas políticas que instituem o poder imperial do português brasileiro numa organização sociolinguística pluri/multilíngue. A partir dessa reflexão, propõe-se uma ampliação teórica da noção de “rizoma” (DELEUZE; GUATTARI, 2011) para o contexto da política linguística como alternativa à supervalorização de uma língua em detrimentos de outras que coexistem num mesmo território. Na perspectiva rizomática de língua, o português do(a) surdo(a), bem como o português de outras comunidades linguísticas historicamente subalternizadas, se insere no rizoma linguístico brasileiro para desestabiliza a hegemonia e a colonialidade linguística e dar visibilidade para uma nova geopolítica das línguas brasileiras.

O letramento literário presente na escola estaria ligado principalmente a um processo de apropriação dos textos em vários níveis, como histórico, poético, estético, teórico, crítico, humanizador, de vivência de alteridades pela leitura. Pensando nesse processo de apropriação, este texto discute o letramento literário relacionado às representações étnico-raciais. Busca, com isso, refletir sobre a importância de tal letramento em um país como o Brasil, em que negros, por exemplo, sofrem ainda as consequências desastrosas de um processo de escravidão, que atualmente se transveste em níveis de violência e mortes vergonhosos. A literatura não se exime de pensar esse processo, e no Brasil há ficcionistas que produzem textos capazes de provocar forte reflexão em sala de aula, por meio de um trabalho de letramento literário. A partir das obras Becos da memória, de Conceição Evaristo, e Um defeito de cor, de Ana Maria Gonçalves, pensaremos a necessidade e a possibilidade de um letramento literário ligado às questões étnico-raciais. Em relação ao letramento literário e ao ensino de literatura, usamos o aporte teórico de Roberto Belo (2016), Antonio Candido (2004), Rildo Cosson (2006), Mary Kato (1986), Magda Soares (2009). Quanto às questões étnico-raciais, nos embasamos em Catharine Walsh (2004), Nilma Lino Gomes (2017) e Bell Hooks (1995, 2013 [1994]).
Integration of AHP and Regression Analysis in Forecasting Attendance in a Movie Theater
Authors: Jamshidi Hossein 
Published: March 2020

Forecasting the number of attendees in a motion picture has often been considered a wild guess since there are many factors or variables involved in forecasting the numbers. There are many contributing factors to consider when attempting forecasting theatre attendance. Among many possible variables the ones with the most significant impact that are considered in this study are; the day that movie is playing, the time of day that movie plays, the ranking of the movie, the genre of movie, the length of time that the movie has been released and finally whether school is in or out. For the most part, these are quantifiable measures and thus should be able to derive an accurate forecasting module. At first, the aim of this study is to compare all the variables by the decision maker based on the Analytical Hierarchy Process (AHP) and to rank the variables based on the importance according to the AHP process. Once the variables are set, the regression analysis is applied to forecast attendance in a movie theater. Multiple regression analysis is used in this study based on a sample of 711 observations. Using SPSS statistical software, a model is developed to forecast the number of attendees and the model provides R2 = 0.760, which is a strong predictor. Finally, the hypothesis test is conducted to verify the accuracy of the regression model with the actual data and even with a = 0.10 the null hypothesis could not be rejected.
Ortega en búsqueda de la circunstancia liberal (1936-1955)
Authors: Bagur Taltavull Juan 
Published: March 2020

El artículo sostiene que la actitud de Ortega entre la Guerra Civil y el Franquismo se explica desde su defensa del liberalismo reformista y el rechazo del comunismo utópico. Esto le llevó a aposar por Franco como un mal menor, identificando al bando republicano con el comunismo. Pero después de la derrota del fascismo en 1945, disminuyó su aceptación del bando vencedor en España, al quedar liberalismo y comunismo enfrentados en el Mundo. La situación excepcional de la circunstancia, le llevó a buscar “espacios de libertad” en España, al tiempo que se comprometía con proyectos europeístas y atlantistas.
The article argues that Ortega´s attitude towards the Spanish Civil War and the Francoism, is based on his defense of the reformist Liberalism and the rejection of the utopian Communism. This led him to support Franco as the lesser evil, identifying the Republicans with the Communists. But, after the defeat of Fascism in 1945, his acceptance of the Dictatorship diminished, due to the confrontation of Liberalism and Communism in the World. The exceptional situation of the circumstance led him to look for “spaces of freedom” in Spain, as the same time as he was committed to pro-European and Atlanticist projects.

The Relationship of Some Kinematic Variables of the Fixed Foot and Body and the Accuracy of Scoring While Performing Penalty by Futsal Players
Authors: Qadr Nihad Ayub 
Published: March 2020

There is a difference in terms of the views of coaches and specialists regarding the fixed foot and position of the body. No study has been noted on futsal in which the variables of the kinematics of the fixed foot and body were analyzed. These variables have a significant importance in terms of the angle of fixed foot and body and their direction and distance. They are important in order to be accurate in scoring and specifically in the fixed balls. The objective of the study was to identify the relationship of some kinematic variables of the fixed foot and body to the accuracy of scoring when performing penalty by futsal players. The research participants were the team of the University of Koya for the academic year 2016-2017. The researcher chose the sample by deliberate method and reached 13 players. Each player has played for at least four years, and all players use the right foot, while the the average age of sample is 23.4 years, body mass 67.37 kg, body height 171 cm, and leg length 93.76 cm. The conclusions of the researcher are that the fixed foot as other parts of the body have an effective role during the scoring of a fixed ball in the game of futsal. The direction angle of the fixed foot has an impact on the mechanical axis of the body and is reflected on the accuracy of the scoring in fixed balls in futsal.
Effect of Salts and Organic Osmolytes is Due to Conservative Forces
Authors: Udema Ikechukwu I. 
Published: March 2020

Background: The impression given in the literature was that the net interaction potential energy, V is the difference between columbic-columbic and total weaker interaction energies. It is proposed however, that in aqueous solution all particles with full formal charges and partial charge (dipoles) contribute to the total interaction as applicable to conservative field but not to the exclusion of hydrophobic interaction if applicable.
Objectives: The objectives are 1) To theoretically elucidate the basis of the intermolecular interaction, 2) To show that effectiveness of an osmolyte which may include inorganic ion to force macromolecular, (un)folding, the m-value, is a function of the implicit mobility (or translational velocity) of the cosolute, 3) To link the m-value to conservative forces (or potential energies, V) and 4) Quantitate the values of V.
Methods: A major theoretical investigation and experimentation using Bernfeld method.
Results and Discussion: There were higher velocities of amylolysis with salt than without it in the presence of ethanol. The magnitude of the calculated V and energy equivalent of the entropic term were higher with higher concentration of ethanol unlike was the case with graphically determined values which were generally higher in magnitude than calculated values. The values of the calculated V and intermolecular distance were respectively higher in magnitude and longer with higher concentration of the salt.
Conclusion: The attractive interaction between a macromolecule and a cationic counter ion is due to long ranged ion-ion interaction which ultimately enhances the effect of short ranged interaction. Higher salt concentration promotes long ranged interaction. The translational velocity of the solvent and cosolute has a role in the quantification of intermolecular distance. A mathematical relationship exists between m-value and - V (or 2 K.E.). The values of V can be calculated based on the derived equations.
Hypophosphatemia in Refeeding Syndrome in Intrauterine Growth Restricted IUGR Neonates Who are Receiving Nutrition: A Prospective Observational Study
Authors: Chaudhary Varunashree , Gohil Jayendra R. , Patel Shreya A. 
Published: March 2020

Objective: Electrolyte dysregulations particularly hypophosphatemia and hypokalemia following feeds in a starved person is known as refeeding syndrome, which may lead to life-threatening conditions like arrhythmias, heart failure, respiratory and neuromuscular compromise. To evaluate electrolyte dyscrasias following enteral or parenteral feeding, among intrauterine growth retardation (IUGR) neonates ie those who were starved in-utero, compared to non-IUGR neonates this study was planned.
Methodology: From March to August 2015, 60 IUGR and non-IUGR neonates who were admitted at birth before starting of nutrition, either by breast milk or electrolyte-free intravenous fluid. An infant was classified as IUGR when his birth weight was <10th percentile according to Fenton or Lubchenco growth charts. Venous blood was collected from intramural babies at zero hours of life or just before starting feeds to determine the basal level of serum electrolytes – phosphorus, magnesium and potassium, and was repeated in the following 48 and 72 hours.
Results: There was no significant difference between the two groups based on sex, history of maternal pre-eclampsia and oligohydramnios. At 72 hours after the start of feeding, Hypophosphatemia was significantly more prevalent, in 33.33% of IUGR vs. 2% of the non-IUGR group, [RR-5, p = 0.010]. Hypokalemia 20% IUGR; 1% non-IUGR group, [RR-6, p = 0.103]. Hypomagnesemia 3% IUGR; 2% non-IUGR group, [RR-1.5, p = 0.640]. Combined electrolyte– hypophosphatemia with hypokalemia (6.6%) and hypophosphatemia with Hypomagnesemia (13.3%), were present only in the IUGR group. Hyperglycemia was not present in any neonate.
Conclusions: IUGR neonates are more likely to develop Refeeding syndrome when compared to non-IUGR babies, manifesting as decreased phosphorus, potassium and magnesium levels. Phosphorous should be a part of feeding nutrition in IUGR babies.

Authors: Maheswaranathan S. 
Published: March 2020

Purpose: This paper investigates the long run relationship between electricity consumption, foreign direct investment and economic growth in Sri Lanka.
Design/Methodology/Approach: The annual time series data over the period 1970–2017 is considered to this study. Augmented Dickey–Fuller (ADF) unit root analysis is employed for examining the stationary properties of the variables. Consequently, Autoregressive Distributed Lag (ARDL) analysis is employed to examining the short- run and long-run relationship between electricity consumption, foreign direct investment and economic growth in Sri Lanka. Further, this study used the diagnostic tests such as the residual normality test, heteroskedasticity and serial autocorrelation tests for misspecification to validate the parameter estimation outcomes achieved by the estimated model. CUSUM test is applied to test the stability of the model. Collected data were analyzed using STATA version 15.
Findings: The findings of the bound test confirm that the variables are cointegrated. Further the results reveal that there is a statistically positive significant relationship between electricity consumption, foreign direct investment and economic growth in Sri Lanka in the long run and short term. The empirical finding reveals that one percent increase in electricity consumption and foreign direct investment increases the GDP by 1.5 percent and 12.9 percent in the long run respectively.
Black Women in Television, a Short History
Authors: Cheers Imani M. 
Published: March 2020

African Americans have been depicted in mass media (film, radio, television) since the turn of the 20th century. When television became the new popular medium for news and entertainment in the late 1940s, the same stereotypes depicted on radio programs and in films migrated to the small screen. Black women have been depicted as maternal mammies and mainstream matriarchs for much of their television representation. These stereotypes have evolved since 1968 in part as a direct result the increase in Black women behind the scenes in creative roles, namely media owners, writers, directors, and showrunners.Mass media conglomerates have historically been under the ownership of White men. Three Black women defied the norm and risen to become media moguls. Catherine L. Hughes (Radio/TV One), Debra L. Lee (BET Networks), and Oprah Winfrey (Oprah Winfrey Network/OWN) have shattered glass ceilings and ascended to a level previously considered unattainable for women in general and Black women specifically.As representation of Black women continues to shift and evolve, so do the labels associated with them. From mammies, sapphires, and jezebels at the turn of the 20th century to Black ladies, matriarchs, and mistress during the 21st century, these shifts are directly related to the increase in media ownership and creative control obtained by Black women.
Adaptive neural prescribed performance output feedback control of pure feedback nonlinear systems using disturbance observer
Authors: Chen Longsheng , Yang Hui 
Published: March 2020

SummaryIn this study, an adaptive output feedback control with prescribed performance is proposed for unknown pure feedback nonlinear systems with external disturbances and unmeasured states. A novel prescribed performance function is developed and incorporated into an output error transformation to achieve tracking control with prescribed performance. To handle the unknown non‐affine nonlinearities and avoid the algebraic loop problem, the radial basis function neural network (RBFNN) is adopted to approximate the unknown non‐affine nonlinearities with the help of Butterworth low‐pass filter. Based on the output of the RBFNN, the coupled design between sate observer and disturbance observer is presented to estimate the unmeasured states and compounded disturbances. Then, the adaptive output feedback control scheme is proposed for unknown pure feedback nonlinear systems, where a first‐order filter is introduced to tackle with the issue of “explosion of complexity” in the traditional back‐stepping approach. The boundedness and convergence of the closed‐loop system are proved rigorously by utilizing the Lyapunov stability theorem. Finally, simulation studies are worked out to demonstrate the effectiveness of the proposed scheme.
Porous Single‐Crystal‐Based Inorganic Semiconductor Photocatalysts for Energy Production and Environmental Remediation: Preparation, Modification, and Applications
Authors: Niu Jinan , Albero Josep , Atienzar Pedro , García Hermenegildo 
Published: March 2020

AbstractSemiconductor photocatalytic and photovoltaic performance depends on crystallinity and surface area to a large extent. One strategy that has recently emergyed to improve semiconductor photoresponse efficiency is their synthesis as porous single crystals (PSCs), therefore providing simultaneously high crystallinity, minimization of grain boundaries, and large specific surface area. Other factors, such as high density of active sites, and enhanced light absorption, also contribute to increased PSC photoresponse with respect to analogous bulk or amorphous materials. This review initially presents the concept and main properties of PSCs. Then, the synthetic routes and the applications as photocatalysts and as photovoltaic devices, mainly in sunlight applications, are summarized. The synthetic procedures have been classified according to the mechanism of pore generation. Applications cover photocatalysis for environmental remediation, solar fuels production, selective photooxidation of organic compounds, and photovoltaic devices. Finally, a summary and views on future developments are provided. The purpose of this review is to show how the use of PSCs is a powerful general methodology applicable beyond metal oxides and can ultimately lead to sufficient photoresponse efficiency, bringing these processes close to commercial application.
Grafting of 3D Bioprinting to In Vitro Drug Screening: A Review
Authors: Nie Jing , Gao Qing , Fu Jianzhong , He Yong 
Published: March 2020

AbstractThe inadequacy of conventional cell‐monolayer planar cultures and animal experiments in predicting the toxicity and clinical efficacy of drug candidates has led to an imminent need for in vitro methods with the ability to better represent in vivo conditions and facilitate the systematic investigation of drug candidates. Recent advances in 3D bioprinting have prompted the precise manipulation of cells and biomaterials, rendering it a promising technology for the construction of in vitro tissue/organ models and drug screening devices. This review presents state‐of‐the‐art in vitro methods used for preclinical drug screening and discusses the limitations of these methods. In particular, the significance of constructing 3D in vitro tissue/organ models and microfluidic analysis devices for drug screening is emphasized, and a focus is placed on the grafting process of 3D bioprinting technology to the construction of such models and devices. The in vitro methods for drug screening are generalized into three types: mini‐tissue, organ‐on‐a‐chip, and tissue/organ construct. The revolutionary process of the in vitro methods is demonstrated in detail, and relevant studies are listed as examples. Specifically, the tumor model is adopted as a precedent to illustrate the possible grafting of 3D bioprinting to antitumor drug screening.

Published: March 2020

AbstractSulfonium salts are playing an increasingly significant role in contemporary organic synthesis. In particular, the generation of radicals from sulfonium salts is a fundamental process in Nature and has been the subject of investigation for over 50 years. However, general synthetic methods that use sulfonium salts as radical precursors are rare. The advent of photoredox catalysis has triggered an upsurge of interest in the radical chemistry of sulfonium salts and this review surveys recent applications of aryl‐ and alkylsulfonium salts in light‐mediated, radical C−C bond formation.magnified image
From Sequence‐Defined Macromolecules to Macromolecular Pin Codes
Authors: Holloway Joshua O. , Van Lijsebetten Filip , Badi Nezha , Houck Hannes A. , Du Prez Filip E. 
Published: March 2020

AbstractDynamic sequence‐defined oligomers carrying a chemically written pin code are obtained through a strategy combining multicomponent reactions with the thermoreversible addition of 1,2,4‐triazoline‐3,5‐diones (TADs) to indole substrates. The precision oligomers are specifically designed to be encrypted upon heating as a result of the random reshuffling of the TAD‐indole covalent bonds within the backbone, thereby resulting in the scrambling of the encoded information. The encrypted pin code can eventually be decrypted following a second heating step that enables the macromolecular pin code to be deciphered using 1D electrospray ionization‐mass spectrometry (ESI‐MS). The herein introduced concept of encryption/decryption represents a key advancement compared with current strategies that typically use uncontrolled degradation to erase and tandem mass spectrometry (MS/MS) to analyze, decipher, and read‐out chemically encrypted information. Additionally, the synthesized macromolecules are coated onto a high‐value polymer material, which demonstrates their potential application as coded product tags for anti‐counterfeiting purposes.
Input/output linearizing controller with Taylor series expansion for a nonminimum phase process by hardware‐in‐the‐loop approach
Authors: Panjapornpon Chanin , Kajornrungsilp Issarush , Rochpuang Chutithep 
Published: March 2020

AbstractInput/output (I/O) linearization is a model‐based control method that receives much attention for many research studies in chemical industries. Despite many advances in control theory, the I/O linearization is not widespread for a real‐time implementation when compared with other model‐based techniques. It requires differentiation and inversion of the process model—which becomes cumbersome as the complexity of the model increases. Thus, this work presents the development and experiment of an embedded I/O feedback control device with a pilot process that emulates an exothermic reactor with nonminimum phase behavior. Algorithms of an approximate I/O linearization control system is truncated by using Taylor series expansion, and it is embedded into a field‐programmable gate array control device. The effectiveness of the embedded approximate I/O controller is compared with a digital proportional‐integral (PI) controller for a test with the pilot process with a hardware‐in‐the‐loop concept. The results show that the embedded model‐based controller provides high performance for the servo problem and disturbance rejection, compared with the PI controller. The proposed embedded model‐based controller shows the application to apply the advance control method into the field‐programmable gate array hardware as a stand‐alone control device, and it can perform the computation of a complex algorithm.
