POLÍTICAS CURRICULARES DE EDUCAÇÃO BÁSICA
Authors: Thiesen Juares da Silva
Published: August 2021

No texto, apresenta-se a sistematização da fala do autor em mesa de trabalho no IX Colóquio de Currículo e Práticas Curriculares promovido pelo Grupo de Estudos e Pesquisa em Políticas Curriculares (GEPPC) da Faculdade de Educação da Universidade Federal da Paraíba em novembro de 2020. O tema da intervenção foi a implantação da Base Nacional Comum Curricular – BNCC em Santa Catarina - movimento que no estado está sendo denominado Implantação do Currículo Base do Território Catarinense. Os pontos de destaque e que orientam a organização do presente artigo são respectivamente: uma breve análise da política curricular brasileira e catarinense, ambas vistas como alinhadas aos discursos internacionalizantes de uma agenda transnacional reformista; a mobilização do pensamento internacional privatista na produção da BNCC no Brasil, e finalmente aspectos da recontextualização dos textos da BNCC no território catarinense. Afirma-se que Santa Catarina faz eficientemente sua tarefa institucional/normativa, acolhendo a lógica da política curricular nacional, com alguma manifestação de crítica e resistência oriundas especialmente dos espaços da academia e sindical.
QUE SE DISPUTA NA/COM A BASE NACIONAL COMUM CURRICULAR?
Authors: Frangella Rita
Published: August 2021

Este artigo examina o contexto de produção da Base Nacional Comum Curricular pondo em discussão elementos destacados como marcos simbólicos das mudanças que a BNCC traz para educação. A eleição desses elementos para análise tem por mote uma peça publicitária veiculada na mídia pelo Ministério da Educação logo após a promulgação da BNCC pelo Conselho Federal de Educação. A narrativa construída assume um tom de acordo consensual que oblitera as disputas em torno dos pontos postos em destaque. Evidenciar essas disputas é objetivo desse texto, argumentando, a partir de uma perspectiva discursiva pós-estruturalista, que essas disputas não cessaram, no entendimento da política como processo de significação contingente, o que implica em lê-la como fechamento provisório, abertura à negociação.
TEORIA ETNOCONSTITUTIVA DE CURRÍCULO E A CONSTRUÇÃO POR PROFESSORES MUNICIPAIS DO “REFERENCIAL CURRICULAR FRANCISCANO”
Authors: Macedo Roberto Sidnei , Dos Santos Cristiana Ferreira
Published: August 2021

O artigo em pauta apresenta o processo pelo qual foi concebido e está sendo implementado pelos(as) professores(as) do município de São Francisco do Conde-BA, o Referencial Curricular Franciscano (RCF), no conjunto das iniciativas municipais do Estado da Bahia, a partir das orientações da Base Nacional Comum Curricular (BNCC) e do Documento Curricular  Referencial da Bahia (DCRB). A singularidade da referida concepção e implementação de política de currículo municipal dá-se pela ampla mobilização dos(as) docentes do município e pelo acolhimento intercrítico desses professores, da Teoria Etnoconstitutiva de Currículo (Citação suprimida), constituída no âmbito do Grupo de Pesquisa FORMACCE PPGE FACED-UFBA. Os dispositivos conceituais acolhidos que operam fundamentalmente em todo processo de configuração da construção do RCF, pautam-se, principalmente, nas concepções de atos de currículo, autorização curriculante, com-versações curriculantes, mediação curricular intercrítica e instituintes culturais da formação, debatidas e ressignificadas pelo coletivo de professores(as) municipais. Ademais, três categorias pautaram de forma transversal os atos de currículo produzidos no processo de concepção, construção e implementação do referido Referencial: política de currículo, trabalho e formação docente.
REDES POLÍTICAS QUE INFLUENCIARAM A ELABORAÇÃO DA BNCC PARA O ENSINO MÉDIO
Authors: Sena Anne Karoline Cantalice , Albino Angela Cristina Alves , Rodrigues Ana Cláudia da Silva
Published: August 2021

Este artigo tem o objetivo de investigar como as redes políticas influenciaram a elaboração, a aprovação e a atuação da BNCC para o Ensino Médio. A abordagem metodológica escolhida foi a qualitativa de cunho exploratório, e o método utilizado foi o estudo de caso (YIN, 2010). Os achados da pesquisa foram organizados considerando-se os dois primeiros contextos do ‘ciclo de políticas’ proposto por Stephen Ball (1994ª) e a técnica de análise de discurso crítico de Fairclough (2016). Considerando os resultados das análises, compreendemos que os contextos de elaboração, aprovação e efetivação da BNCC do Ensino Médio foram permeados por discursos neoliberais com forte apelo filantrópico e mercadológico, provenientes das agências nacionais e internacionais que utilizam mecanismos para manter sua atuação, como seminários e congressos anuais, em que se discute sobre as ações para a educação do país e as direcionam. Como consequência, depois de aprovada a BNCC, outras políticas estão sendo elaboradas com o intuito de direcionar a Formação Inicial e continuada de professores para a Educação Básica e os Projetos Pedagógicos dos cursos de licenciatura, cuja orientação é para considerar, a priori, as determinações dos documentos que vincularam diretamente a formação docente às exigências políticas neoliberais da BNCC, promovendo, inevitavelmente, uma concepção neotecnicista e empresarial no sistema de ensino público.

O trabalho aborda a luta política no âmbito curricular empenhada pelas Escolas de Assentamentos e Acampamentos do MST organizadas em Ciclos de Formação Humana com Complexos de Estudo contra a imposição da padronização curricular representada pela BNCC e pelo CREP. É resultado de pesquisa bibliográfica, legal (marcos regulatórios) e documental, assim como de vivência prática dos autores no trabalho com as escolas. Trazemos a concepção de Educação do Campo e a materialidade de sua origem e vínculo, a concepção de currículo e a incidência da Pedagogia do Capital na elaboração e definição da BNCC e do CREP como expressão do mercado. Discorremos sobre elementos da trajetória de elaboração curricular da educação do MST, explicitando dimensões da organização curricular por Ciclos de Formação Humana com Complexos de Estudo. Refletimos sobre os impactos iniciais na organização curricular traduzida pela imposição do CREP e como os coletivos escolares têm se movimentado coletivamente para fazer a resistência ativa. Destacamos que a experiência, evidencia por meio da articulação das diferentes dimensões curriculares a amplitude estruturante para a prática curricular que transcendem ao ensino livresco e verbalista, por meio da relação do uso de conceitos, categorias e procedimentos das diferentes ciências e artes na relação com a realidade e conectada as matrizes pedagógicas do trabalho, da cultura, da organização coletiva, da história e da luta social para constituir pilares de resistência ativa contra a ingerência das políticas curriculares hegemônicas.
DIREITO À EDUCAÇÃO NA PANDEMIA
Authors: Hage Salomão Antônio , Sena Ivânia Paula Freitas de Souza
Published: August 2021

As orientações dos órgãos de gestão pública e de controle social das políticas educacionais para o período emergencial da pandemia, tem apresentado soluções burocráticas e padronizadas para dar seguimento ao ano letivo e ao currículo nas redes e sistemas de educação. O presente artigo traz uma análise do cenário da educação com base nas reflexões de coletivos da Educação e do Campo, objetivando colocar em debate como o Estado brasileiro vem negligenciando o direito à educação, tendo em vista a centralidade dada à BNCC e a legitimação do ensino remoto, que enfraquecem a formação humana integral dos estudantes e colaboram, de forma expressiva, para a desresponsabilização do Estado para com as políticas estruturantes que viabilizam a oferta da educação com qualidade, durante e depois da pandemia. Conclui-se que para superar tais contradições, é fundamental que o Estado brasileiro e órgãos de controle social, aprofundem a análise sobre as condições efetivas da ofertada da educação na pandemia e ampliem os canais de diálogos com as comunidades e escolas, visando conhecer as diferentes realidades e, assim, construir saídas concretas que assegurem o direito à educação para todos e todas.

História externa da Língua portuguesa
Authors: Melo Pedro Antonio Gomes de
Published: August 2021

Afirmar que a língua portuguesa tem a sua origem no latim falado na Península Ibérica pelos povos romanizados é repetir o óbvio; no entanto, deve-se advertir que o termo latim, não é unívoco, já que existem variedades do idioma dos romanos como: sermo urbanus – linguagem do estrato social mais culto e o sermo plebeius – linguagem da massa popular inculta: rusticus (camponeses), castrenses (militares) e peregrinus (estrangeiros). Em razão disso, busca-se, neste texto, enfatizar que a língua portuguesa é uma continuação do latim popular, com suas diversas variedades sociais, que se prolongou no romance galego-português, uma variante do latim que constitui um estágio intermediário entre o latim vulgar e as línguas românicas modernas - atualizando-se, em sua evolução no tempo e no espaço, no atual Português usado no Brasil.
aparecimento do inseto como instante poético e reflexivo em "Uma esperança", de Clarice Lispector
Authors: Costa Fabrício Lemos da , Holanda Sílvio Augusto de Oliveira
Published: August 2021

O presente estudo tem objetivo de analisar o aparecimento de um inseto como motivo poético e reflexivo em “Uma esperança”, décimo quatorze texto do livro Felicidade Clandestina (1998), de Clarice Lispector (1920-1977). Trata-se de um breve flagrante do pequeno vivente no cotidiano de uma família, transformado em matéria de ficcionalização. Assim, neste trabalho, desenvolveremos uma abordagem que considera o inseto como parte de um projeto literário desta escritora, que vê em miúdos animais uma oportunidade de capturar a “beleza” do instante em simplicidade e subjetividade. Para a nossa interpretação, recorremos aos estudos de Giorgi (2016), Maciel (2016), Nascimento (2012), Mendes (2000) e Santiago (2006).
Deus e o nada
Authors: Ribeiro Merissa Ferreira , Ferraz Antonio Maximo von Sohsten Gomes
Published: August 2021

O presente artigo tem como objetivo apresentar como a figura de Deus manifesta a natureza (physis) em “Perdoando Deus”, de Clarice Lispector, e nos versos de “Poemas Malditos Gozosos e Devotos”, de Hilda Hilst. Os dois escritos dialogam ao subverterem a palavra em seu sentido funcional, trivial, o qual não permite a instauração do Nada – termo tão caro às obras destas autoras. O Nada, tanto em Clarice quanto em Hilda, não tem a ver com niilismo, ao contrário: diz sobre o ato criador, que só vem à luz quando se abre um espaço (vazio) capaz de recolocar a linguagem em seu silêncio. É por este motivo que a figura de Deus se faz presente nos dois textos sobre os quais explanaremos, evocando a plenitude do ato criativo, que só é possível quando o Nada está em cena. Deus é este ser que cria e destrói, mas tal destruição também é criadora, pois abriga possibilidades. Utilizamos, para discorrer sobre tais aspectos, o método hermenêutico, que desemboca em um movimento cíclico o qual permite ao intérprete, ao questionar a obra, também se perceber, ele próprio, como questão. Para dialogar com as obras explanadas, consideramos os apontamentos de Martin Heidegger acerca da verdade.

Comparison of Students’ Learning and Attitudes in Physical versus Virtual Manipulatives using Inquiry-Based Instruction
Authors: Oymak Onur , Ogan-Bekiroglu Feral
Published: August 2021

This research aimed to determine whether implementation of virtual technology or implementation of physical materials in a learning environment is more efficient in understanding physics concepts and developing positive attitudes at the high school level. The theory that framed this study is the model of learning as dynamic transfer. Participants were 96 ninth grade students (n = 96) distributed randomly to the virtual or physical group. Inquiry-based instruction continued during teaching of kinematics and dynamics, which lasted for eight weeks for both groups. Data from the Force and Motion Achievement Instrument (FMAI), student worksheets, the Attitude Towards Physics Scale (APCS), and anecdotal observations were collected. This study concluded that the use of physical and virtual manipulatives in inquiry-based instruction had the same effect on students’ conceptual and procedural knowledge, as well as their attitudes towards physics. However, students who dealt with physical experimentation had lower learning than their peers who experienced virtual experimentation due to measurement errors made by students. Furthermore, physical investigations left students with some irrelevant knowledge. Therefore, it is reasonable to assume that implementing virtual manipulatives is more advantageous for learning in some conditions. The final conclusion is that attitude and learning may be developed in a parallel manner.
Five Tips from Filmmakers: An Online Instructional Module for Documentary Film Research
Authors: Iwasaki Patsy Y.
Published: August 2021

Information about the overall documentary filmmaking process is available; however, there is a lack of literature and educational resources about how to conduct subject research and data collection. As documentary filmmaking becomes an increasingly democratic endeavor due to technology, and information distribution and education use increases, there is a corresponding need for quality resources to support this essential step. In this study, a content-rich, technology-enhanced, online instructional module that was designed and developed in another study to guide and assist beginner documentary filmmakers with subject research and data collection, was implemented and evaluated by the target audience. This module featured five filmmaking tips summarizing professional documentary filmmakers’ wisdom and expertise with subject research and data collection. Motivational and instructional models served as frameworks to inform and guide the study’s learning design process. The quantitative and qualitative findings, field notes and observations provided data triangulation. After analysis and interpretation were completed, the results significantly confirmed the module had a positive, educational impact on the target audience and accomplished its purpose. This module addressed the lack of resources and utilized consultation of experts in content design and development to improve the creativity and production of beginner documentary filmmakers. This project successfully merged learning sciences theory and instructional design with humanities and arts research. It will contribute to the literature of documentary film research studies, the fields of instructional design and education, and the humanities. It has significant potential to influence and impact the broad possibilities of innovative, interdisciplinary research design and collaboration.

Published: August 2021

The main protease of SARS-CoV-2 (called Mpro or 3CLpro) is essential for
processing polyproteins encoded by viral RNA. Macromolecules adopt
several favored conformations in solution depending on their structure
and shape, determining their dynamics and function. Integrated methods
combining the lowest-frequency movements obtained by Normal Mode
Analysis (NMA), and the faster movements from Molecular Dynamics (MD),
and data from biophysical techniques, are necessary to establish the
correlation between complex structural dynamics of macromolecules and
their function. In this article, we used a hybrid simulation method to
sample the conformational space to characterize the structural dynamics
and global motions of WT SARS-CoV-2 Mpro and 48 mutants, including
several mutations that appear in P.1, B.1.1.7, B.1.351, B.1.525 and
B.1.429+B.1.427 variants. Integrated Hybrid methods combining NMA and MD
have been useful to study the correlation between the complex structural
dynamics of macromolecules and their functioning mechanisms. Here, we
applied this hybrid approach to elucidate the effects of mutation in the
structural dynamics of SARS-CoV-2 Mpro, considering their flexibility,
solvent accessible surface area analyses, global movements, and
catalytic dyad distance. Furthermore, some mutants showed significant
changes in their structural dynamics and conformation, which could lead
to distinct functional properties.

Published: August 2021

Introduction/Objective. Pancreatic cancer may be accompanied by infections caused by various microorganisms. It is uncertain wheatear pancreatic infection precedes the development of cancer or vice versa. The aim of this study is to analyze routes of infections from the duodenum through the pancreatic duct to determine what types of microorganisms can get through this duct into the pancreas and nearby tissue. Methods. In patients subjected to cephalic duodenopancreatectomy (Whipple procedure) due to adenocarcinoma of the ampulla of Vater, the duodenum or head of the pancreas, swabs from duodenal mucosa, pancreatic duct, and pancreatic tissue at the line of the resection were taken. Microscopic slides were prepared directly from the patients? specimens as well as from colonies on culture plates, and both were Gram stained. Results. Candida was present in all three types of swabs (duodenum, pancreatic duct, and tissue), while bacteria, depending on the species (Pseudomonas aeruginosa, ?-hemolytic Streptococcus, coagulasenegative Staphylococcus, Enterococcus spp., Serratia spp.), were present in pancreatic duct or tissue, but not in the duodenum. Conclusion. There is a connection between the presence of microorganisms and pathology of the pancreatic adenocarcinoma. Results show that Candida infection originates from the duodenum, while bacterial infections originate directly from blood or tissue injuries.
Dietary intake of linoleic acid, its concentrations and the risk of type 2 diabetes: a systematic review and dose-response meta-analysis of prospective cohort studies
Authors: Mousavi Seyed Mohammad , Jalilpiran Yahya , Karimi Elmira , Aune Dagfinn , Larijani Bagher , Mozaffarian Dariush , Willett Walter C. , Esmaillzadeh Ahmad
Published: August 2021

Background: Earlier evidence on the association
between dietary PUFAs and risk of diabetes has been conflicting.

Purpose: To quantitatively summarize previous studies on the
association between dietary LA intake, its biomarkers, and the risk of type 2
diabetes mellitus (T2DM) in the general population.

Data source: PubMed/Medline, Scopus, and ISI
Web of Science until 24 October 2020, and reference lists of all related
articles, and key journals.

Study selection: Prospective cohort studies that
examined the associations of LA with the risk of T2DM in adults.

Data synthesis: The inverse variance method was
applied to calculate summary relative risk (RR) of LA intake and its
biomarkers, and dose-response associations was modeled using restricted cubic
splines. Twenty-three publications,
covering a total of 31 prospective cohorts, were included; these studies
included 297,685 participants (22,639 incident diabetes cases) with dietary
intake assessment and 84,171 participants (18,458 incident diabetes cases) with
biomarker measurements. High
intake of LA was associated with a 6% lower risk of T2DM (summary relative risk
(RR): 0.94, 95% confidence interval (CI): 0.90, 0.99; I2=48.5%). In the dose-response analysis, each
5% increment in energy from LA intake was associated with a 10% lower risk of
T2DM. There was also evidence of a linear association between LA intake
and diabetes, with the lowest risk at highest intakes. The summary RR for
diabetes per SD increment in LA concentrations in adipose tissue/blood
compartments was 0.85 (95%CI:
0.80, 0.90; I2=66.2%). The certainty of the evidence was assessed
as moderate.

Limitation: Observational design of studies
included in the analyses.

Conclusions: We found that a high intake of dietary LA and elevated concentrations of LA in the
body were both significantly associated with a lower risk of T2DM. These findings support dietary recommendations
to consume dietary LA.

Stem cell derived beta-like cells (sBC) carry
the promise of providing an abundant source of insulin-producing cells for use
in cell replacement therapy for patients with diabetes, potentially allowing
widespread implementation of a practical cure. To achieve their clinical
promise, sBC need to function comparably to mature adult beta cells, but as yet
they display varying degrees of maturity. Indeed, detailed knowledge of the
events resulting in human beta cell maturation remains obscure. Here we show
that sBC spontaneously self-enrich into discreet islet-like cap structures
within in vitro cultures, independent
of exogenous maturation conditions. Multiple complementary assays demonstrate
that this process is accompanied by functional maturation of the self-enriched
sBC (seBC); however, the seBC still contain distinct subpopulations displaying
different maturation levels. Interestingly, the surface protein ENTPD3 (also
known as nucleoside triphosphate diphosphohydrolase-3 (NDPTase3)) is a specific
marker of the most mature seBC population and can be used for mature seBC identification
and sorting. Our results illuminate critical aspects of in vitro sBC maturation and provide important insights towards
developing functionally mature sBC for diabetes cell replacement therapy.
Optimisation of hybrid renewable energy systems on islands: A review
Authors: Morales Lassalle James , Figueroa Martínez Dante
Published: August 2021

Access to energy services is recognised as a fundamental aspect of economic and social development. This is particularly important for isolated areas, where electrical supply is not guaranteed. Because of their inherent geographic characteristics, islands are prominent cases of isolated areas that must import and burn fossil fuels, with environmental and economic consequences. In this context, Hybrid Renewable Energy Systems (HRES) emerge as an alternative to traditional generation to reduce energy costs and environmental issues. This study aims to demonstrate the feasibility of implementing HRES on islands, based on energy optimisation. We present an extensive review of HRES optimisations across 73 island cases, collecting information about energy demand, energy system sizes, and optimisation methodologies. The most commonly proposed HRES components are identified, and a significant power relationship is found between population and annual energy demand on islands. Further, we identify islands with higher-than-expected and lower-than-expected consumption and the underlying causes. The main limitations of the reviewed studies are discussed, particularly with regards to availability and quality of hourly demand data and/or meteorological data required for renewable energy assessments. Several approaches to fill these gaps in information are reviewed here, concluding with a discussion of emergent methods and technologies.
(Un)Making smallness: Islands, spatial ascription processes and (im)mobility
Authors: Nimführ Sarah , Otto Laura
Published: August 2021

Official categorization systems classify some states, including island-states, as small. Malta, located in the Mediterranean Sea, is one of six European microstates and the European Union’s smallest member state. Smallness, however, refers to more than fixed geographic scales. The understanding of smallness developed in this article, in contrast, moves beyond geographic features and argues instead that smallness is related to perceptions, experiences, and ascriptions. We challenge universal understandings of smallness against the backdrop of ethnographic research carried out in Malta (2013–2018) by exploring how island-related smallness is produced and used situationally in the context of (im)mobility. By focusing on narratives of smallness by various actors with whom we engaged during fieldwork, we demonstrate how smallness, islandness, and (im)mobilizing policies intersect at the EU’s external border. In addition, and in order to contribute to decolonial perspectives within Island Studies, we reflect on our role in (un)making smallness. We discuss our understandings of smallness against the backdrop of our empirical material and scholarly debates, and, in so doing, avoid the reproduction of universal understandings. In this vein, we argue for the deconstruction of simplified interpretations of smallness and claim that smallness must be viewed as a relational concept.

Published: August 2021

Abstract—Indonesia located in the equatorial region which has potential to have a major impact on atmospheric physical conditions during extreme weather events such as the Mesoscale Convective Complex (MCC). MCC is a phenomenon that was first discovered by (Maddox, 1980) where this phenomenon is characterized by the presence of a quasi-circular (almost circular) cloud shield with an eccentricity of 0.7 with a cloud cover area of 100,000 km², the cloud core area covers 50,000 km² and cloud top temperature IR1 -52 ℃. These cloud conditions last for a minimum of 6 hours and cause severe weather and extreme rain. This study aims to identify the MCC phenomenon in the Karimata Strait on 19-20 September 2020 which caused heavy rains in parts of the West coast of Kalimantan and Bangka Island using Himawari-8 Satellite imagery data and the MATLAB application. The results showed that on September 19, MCC was identified at 09.00-19.00 UTC, then on September 20, MCC was identified at 16.00-23.00 UTC. At the time of the MCC event, Bangka and Pontianak regions experienced extreme rains recorded on AWS Digi Stamet Pontianak with rainfall reaching 43.4 mm/hour and ARG Lubuk Besar Bangka Tengah with rainfall reaching 16.8 mm/hour.

Iron removal from ground water using Egyptian cost-effective clay minerals
Authors: Abdel-Ghafar Hamdy Maamoun , Abdel-Aal ElSayed , El_anadouli Bahgat
Published: August 2021

Glauconite and kaolin are used as adsorbent materials for iron removal from synthetic solutions. Different concentrations of iron solutions have been prepared (10, 20 and 30 mg/L). Different dose of glauconite and kaolin were added (0.1, 0.55 and 1.0 g). Statistical design was used to determine the optimum conditions of iron adsorption on glauconite and kaolin. It is shown that glauconite has high adsorption for iron reaching to 95% while kaolin has lower adsorption for iron. Physical and chemical characterization of glauconite and kaolin was tested. High surface area of glauconite (19.8 m2/g) compared to kaolin (5.4 m2/g) explains its high removal efficiency.
Kinetics of dechlorination of atrazine using tin (SnII) at neutral pH conditions
Authors: Kumar Vijay , Singh Simranjeet
Published: August 2021

Atrazine is a broad spectrum herbicide of triazine family. It is a chlorine-containing molecule and it can persist in environment. Chemical and biochemical techniques are the main techniques used to decompose the chemicals. In pre-sent study, the dechlorination of atrazine (Atr) via reaction with Sn(II) ion under aqueous media at neutral pH condi-tions was studied. The observed dechlorinated metabolite was 4-Ethylamino-6-isopropylamino-[1,3,5]triazin-2-ol. Identification of dechlorinated product of Atr was performed by using spectroscopic (FTIR) and mass (ESI-MS) spectrometric analysis. The kinetics of the dechlorination of Atr was measured by using pseudo-first order kinetics. The observed reaction constants was, kobs = 6.11x10-2 (at 430 mg/ L of Atr), and kobs = 6.14 x10-2 (at 215 mg/ L of Atr). The calculated half-life (t1/2) period was, t1/2 = 0.204 d (at 430 mg/ L of Atr), and t1/2 = 0.205 d (at 215 mg/ L of Atr).

Published: August 2021

This study investigated elimination of Cu+2 and Pb2+2 from prepared stock solutions using MgO, nanostructured MgO sorbents. The maximum cumulative values for copper and lead were 410, 200, 494.9, and 214.6 mg g-1, for nanostructured MgO, MgO, respectively. Freundlich and Langmuir models describe the sorption equilibrium isotherms. Freundlich model gives the best interpretation for experiment data for these ions.The most adequate model describing the kinetic with the experimental data using MgO, nanostructured MgO was a first-order kinetic model. Nanostructured MgO probably has an efficient way to remove metal ions due to its high capability to adsorb these ions.

Superoxide dismutase (SOD), catalase (CAT), Glutathione reductase (GR) and lipid peroxidation levels of leaves of Elodea canadensis which was exposed to different concentrations of heavy metals (Cd: 2, 5, 10, 15, 25 ppb; Cu: 200, 500, 1000, 2500 ppb and Cr: 1, 3, 10, 15, 25 ppb) in a hydroponic culture were determined spectrophotometrically. The highest induction in SOD and CAT activities were determined at highest concentration of heavy metals. The Random Amplified Polymorphic DNA Polymerase Chain Reaction (RAPD-PCR) technique was used to investigate the variation of DNA banding patterns of samples that exposed to different concentrations of heavy metals. Changing in band intensity and the gain and loss of bands were demonstrated the genotoxic effect of heavy metals. Bioaccumulation, oxidative responses and DNA damages were shown that Elodea canadensis represents a useful bioindicator.

Published: August 2021

In recently few years, application of membrane technologies in sea water desalination is increased compared to other desalination technologies. Electrodialysis membrane technology is still limited in seawater desalination due to the high operation cost and its limitations for high salty water. Electrodialysis desalination cost is proportional to the amount of salt, which must be carried out through the membrane. Seawater desalination with high salt content of NaCl (42 g/L) was applied using IonTech electrodialysis unit. Partial desalination process was studied in two separate experiments, batch and continuous operation. Operation parameters like voltage applied, electrolyte concentration and time of desalination were studied under batch mode process. Continuous operation process was carried out to confirm the partial desalination process of electrodialysis. The limited current density is determined, 1.49 A/m2 and 1.15 A/m2 for theoretical and experimental, respectively. The specific energy consumption was calculated, 7.15 kWh/m3.

Published: August 2021

In the current research, the vegetable oil based polyurethane nanocomposite (PUNC) adhesive was prepared using transesterified castor oil (CO) based polyol, partially biobased aliphatic isocyanate (PBAI) and organically modified montmorillonite nanoclay (Closite 30B). The transesterified CO was synthesized by reacting CO with ethylene glycol, which was confirmed using proton nuclear magnetic resonance (1HNMR) analysis. Further, the prepared polyurethane (PU) and its nanocomposite adhesive with specific NCO: OH molar ratio 1.3:1 was confirmed by Fourier transform infrared spectroscopy (FTIR) analysis. The increasing of wt% of nanoclay loading level up to 3% into PU matrix increased the lap shear strength of the adhesive systems. Subsequently, the effect of polyurethane nanocomposite adhesives on the bonding strength of wood-to-wood and aluminum-to-aluminum substrate was studied using lap shear strength test. The nanoclay was observed to effectively intercalate into the polymer matrix. Moreover, the phase separation in PU and PUNC adhesive was studied using atomic force microscope (AFM) and differential scanning calorimetry (DSC) analysis.

Authors: Khan Mahfoozurrahman , Mohammad Ali , Ullah Qasim , Mohammad Faiz
Published: August 2021

This article studies a new green eco-friendly TLC (thin layer chromatography) using silica gel and polyaniline modified silica gel as stationary phase in combination with ethyl acetate (EA), n-butyl acetate (BA) and butane-1-ol (BO) solutions as mobile phase for the comparative study of migration behaviour of organic dyes to identify the most suitable thin layer chromatographic system for the resolution of co-existing dyes. Better separation efficiency was observed by modifying silica gel with polyaniline as compared to pure silica stationary phase. Densitogrpahic presentation of separations achieved on polyaniline modified silica gel Pani@SG-EB1 was also presented. The thin layer chromatographic system comprising of polyaniline modified silica gel Pani@SG-EB1 as stationary phase and n-butyl acetate:DDW, 5:5 as green mobile phase was observed to be the most favourable for the separation of various combinations of three or four-component mixtures of organic dyes viz. methyl thymol blue, tartrazine, carmoisine, rose bengal, amidoblack 10B, bromopyrogallol red and 4-nitrobenzene dizonium tetrafluoroborate. The effect of presence of cations and anions on separation trend was also examined and the limits of detection of the separated organic dyes were estimated. Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron micrograph (TEM) studies were undertaken to characterize silica gel and modified silica gel (stationary phase). The developed method has been successfully applied for the identification of carmoisine in Solvin cold DS syrup and tartrazine in MefastTM syrup.
An integrative review of lateral line depigmentation in marine and freshwater fish
Authors: Dannemiller Nicholas G. , O'Connor Matthew R. , Bonn William G. Van
Published: August 2021

OBJECTIVE

To qualitatively review reports on lateral line depigmentation (LLD) in marine and freshwater fish.

SAMPLE

English-language publications concerning LLD published before March 1, 2020.

PROCEDURES

Electronic searches of CAB abstracts, PubMed, and Web of Science databases and the proceedings of the International Association of Aquatic Animal Medicine were performed. Records were systematically screened and selected for inclusion in an integrative review. Bibliographies of records included in the review were examined to identify other records to be screened. Included records were qualitatively reviewed. Evidence level and quality were graded according to previously described criteria. Information pertinent to epidemiological factors, etiopathogenesis, clinical and histopathologic findings, treatment, and prevention of LLD was collected.

RESULTS

401 records were screened, and 24 unique publications (16 peer-reviewed articles, 1 textbook, and 7 abstracts) were included in the study; 12 (50%), 1 (4%), 6 (25%), and 5 (21%) were classified as evidence level I (experimental), II (quasi-experimental), III (nonexperimental), and V (clinical reports or clinician experience), respectively. Seventeen (71%) and 7 (29%) reports were classified as high quality and good quality, respectively.

CONCLUSIONS AND CLINICAL RELEVANCE

LLD should be considered a clinical observation indicative of a dermato-logic response of fish to suboptimal conditions; LLD should continue to be adopted as the preferred term to describe the classic signs. Whereas gross findings are similar among species, histologic findings can vary. Evidence-based treatment of LLD for individual fish consists of source control (changing tanks or systems), topical treatment with 0.01% becaplermin gel, supportive care, and antimicrobial treatment when warranted. For schools of fish, treatment and prevention of LLD should be focused on improving suboptimal environmental and physiologic conditions. (J Am Vet Med Assoc 2021;259:617–625)

Published: August 2021

OBJECTIVE

To evaluate the utility of an automated insulated isothermal PCR (iiPCR) system for rapid and reliable on-site detection of African swine fever virus (ASFV) in swine biological samples.

SAMPLE

Lymph node, tissue homogenate, whole blood, serum, spleen, and tonsil samples collected from swine in North and South Vietnam.

PROCEDURES

Analytic sensitivity of the iiPCR system was determined by serial dilution and analysis of 2 samples (swine tissue homogenate and blood) predetermined to be positive for ASFV. Analytic specificity was assessed by analysis of 2 samples predetermined to be negative for ASFV and positive or negative for other swine pathogens (classical swine fever virus, porcine reproductive and respiratory syndrome virus, foot-and-mouth disease virus, and porcine circovirus type 2). Diagnostic performance of the iiPCR system for detection of ASFV was determined by analysis of the various tissue sample types. For all tests, a real-time PCR assay was used as the reference method.

RESULTS

The iiPCR system was able to detect ASFV in swine blood or tissue homogenate at dilutions up to 106, whereas the real-time PCR assay was able to detect dilutions of up to 105 or 106. The iiPCR system had high analytic specificity for detection of ASFV versus other swine pathogens. Between 97% and 100% agreement was found between results of the iiPCR system for the various tissue samples and results of real-time PCR assay.

CONCLUSIONS AND CLINICAL RELEVANCE

The evaluated iiPCR system was found to be a rapid, reliable, and sample-flexible method for ASFV detection and may be useful for disease surveil-lance and quarantine in national strategies for early ASF control.
CLT for single functional index quantile regression under dependence structure
Authors: Kadiri Nadia , Rabhi Abbes , Khardani Salah , Akkal Fatima
Published: August 2021

In this paper, we investigate the asymptotic properties of a nonparametric conditional quantile estimation in the single functional index model for dependent functional data and censored at random responses are observed. First of all, we establish asymptotic properties for a conditional distribution estimator from which we derive an central limit theorem (CLT) of the conditional quantile estimator. Simulation study is also presented to illustrate the validity and finite sample performance of the considered estimator. Finally, the estimation of the functional index via the pseudo-maximum likelihood method is discussed, but not tackled.

Published: August 2021

Objective

To explore the changes of proopiomelanocortin (POMC) and Agouti-Related Peptide (AgRP) expression in brain and kidney tissues under insulin intervention at different stages of diabetic nephropathy (DN) rats.

Methods

The male Sprague-Dawley (SD) rats of DN were treated with high-fat diet for 8 weeks and induced by intraperitoneally injection of streptozotocin (30 mg/kg) for one time. Then DN rats were also injected insulin subcutaneously at 2–5 U/(kg·24 h) from initiation of the streptozotocin. Kidney tissue, blood sample, and 24 h-urine were collected to detect the ratio of kidney/body weight, blood glucose and 24-h urinary albumin excretion rate at different stages (4, 8, 12, and 16 weeks). Immunohistochemistry assay was used to measure the expression of POMC and AgRP at different stages of DN rats.

Results

The DN rats were established successfully. With the progression of DN, blood glucose, 24-h urinary albumin excretion rate and kidney body weight ratio increased significantly, while decreased when insulin was injected. Immunohistochemistry showed that the expression levels of POMC were decreased gradually in brain and kidney tissues. Conversely, the expression of AgRP in kidney was highest at week 8 and then decreased gradually. The effect of insulin on normalizing POMC and AgRP expression in brain and renal tissues was also observed in DKD rats.

Conclusion

With the progression of DN, the expression of POMC and AgRP in kidney tissues was observed at different stages of disease, and their expressions were significantly normalized by insulin. The mechanism of in situ expression of POMC and AGRP in kidney to the progression of DN needs further investigations.
Simultaneous membranous nephropathy and diabetic nephropathy occurrence in a patient: A case report
Authors: Tian Binyao , Liu Nan , Xu Tianhua , Liu Xiaodan , Yao Li
Published: August 2021

Membranous nephropathy (MN) is the most common glomerular disease in adults and is constantly associated with the occurrence of nephrotic syndrome. While diabetic kidney disease (DKD) and diabetic nephropathy (DN), which often occur in diabetic patients, are considered as the major causes of end-stage kidney disease. Actually, MN often occurs in patients with diabetes mellitus (DM), but to obtain a clear differential diagnosis without a renal biopsy has become difficult. Here we report the case of a female diabetic patient who developed both MN and DN simultaneously.
