METHOD FOR MANUFACTURING THIN FILMS OF CUBI2O4 FOR PHOTOELECTROCHEMICAL APPLICATIONS
Authors: Puzikova D.S. , Dergacheva M.B. , Khussurova G.M.
Published: April 2020

A method has been developed for producing thin semiconductor films of a complex copper-bismuth system (CuBi2O4) with reduced roughness and increased photoactivity.
The application process is carried out under standard laboratory conditions from aqueous solutions of salts, takes advantage of centrifugation to evenly distribute the coating over the surface, is characterized by low material consumption, and allows the thin nanocrystalline layers formation with a given thickness. Polyethylene glycol (PEG) is used to improve the spraying of solution droplets over the entire surface of the CuBi2O4 film, which allows the dense uniform films deposition.
Scanning electron and atomic force microscopy data demonstrate the ordering of the growth of CuBi2O4 particles (size ≈200 nm) and a 1.5-fold decrease in the roughness of the relief when polyethylene glycol is added to the solution. Micrographs show the growth of uniformly sized rounded crystallites.
In a comparative analysis of the XRD diagram of the samples, an increase in the number and intensity of peaks corresponding to the crystalline phase of Kusachiite (CuBi2O4) with the introduction of PEG into the initial solution is observed.
Based on the photoelectrochemical measurements results, it was found that the addition of polyethylene glycol to the electrolyte helps to increase the photoactivity of the samples by 2 times.
The obtained thin polycrystalline CuBi2O4 films are promising for use in photoelectrochemical converters.
Keywords: Solar energy material, spin coating, CuBi2O4, polyethylene glycol.

Published: April 2020

In the article we propose the method of calculation of parameters of stress state and rigidity of screw blade at bending in one plane, screw-piston press of BТ-3М grade for production of coal briquettes is simultaneously mixing, transporting and pressing unit. The blade is regarded as a thin axially endless helicoid shell rigidly attached to the shaft along an internal helical boundary. Considering that the presence of the blade does not affect the deformation of the constant-section shaft during bending, we examine the effect of the presence of the blade on the bending stiffness of the screw. Invention covers the problem of screw blade deformations at preset displacements at inner boundary caused by shaft bending considering that its axis has curvature.
In the second stage of calculation we construct a compensating solution, which eliminates inconsistencies in differential equilibrium equations and static boundary conditions, and on the inner contour of the shell we set conditions of rigid pinching. As a result, the screw was calculated using the developed method. Blade is calculated with parameters r1 = 0.04 m, r2 = 0.1 m, r3 = 0.03 m, screw blade thickness d = 0.005 m, L = 0.2 m, total length of hollow shaft 1, 2 m. Calculations have shown that at such screw parameters and created specific pressure of material on the screw Ore = 8.5 · 105 Pa, the rigidity of the blade is the stiffness 11% of the tubular shaft.

Filosofia no ensino fundamental: formando cidadãos críticos?
Authors: Sanchez Liliane Barreira , Motta Jaqueline da Cunha
Published: April 2020

Este artigo apresenta os principais pontos do programa “Filosofia para Crianças”, criado pelo filósofo norte-americano Matthew Lipman na década de 1960, que propõe a introdução da disciplina filosofia no ensino fundamental e na educação infantil, expondo seus fundamentos e métodos. Explica alguns conceitos-chave do programa, tais como o ideal de democracia e de “comunidade de investigação”, analisando sua relação com o sistema escolar e a sociedade instituída. Realiza críticas a alguns aspectos desse programa e questiona a coerência e a pertinência de sua pretensão filosófica e de formação crítica, contrapondo o seu modelo antropológico ideal, baseado na valorização do potencial racional do humano, a uma visão antropológica menos definida e delimitada.

Ensino de filosofia na era da pós-verdade
Authors: Ceppas Filipe , Rocha Raquel Rodrigues
Published: April 2020

Neste texto, procuramos situar o ensino de filosofia em meio ao panorama da pós-verdade, enquanto novo horizonte de comunicação hegemônico de nossa época. Apresentamos algumas características centrais e nefastas da pós-verdade, como a polarização comunicativa das bolhas digitais e a natureza viral das fakenews, como decorrentes, sobretudo, da ampliação do controle de dados na internet. Ao longo desta apresentação, nos perguntamos sobre as relações que esses fenômenos guardam com a filosofia: a relação que a pós-verdade guarda com a verdade; como situar o problema numa compreensão filosófica mais ampla acerca da contemporaneidade; e como pensar a potência dos regimes de verdade construídos pela filosofia enquanto uma estratégia pedagógica imunitária frente ao caos da “era da pós-verdade”.

Introdução do Editor

Nesta edição da O que nos faz pensar dedicada ao ensino de filosofia, aproveitamos para publicar, como um documento que dá testemunho histórico a respeito da educação, um texto de 1988 de Therezinha Gonzaga Ferreira Lessa. Therezinha formou-se em Pedagogia e fez Mestrado em Educação na UFRJ. No entanto, a sua trajetória foi marcada sobretudo pela relação com o CEAT – Centro Educacional Anísio Teixeira. Fundado em 1969, ainda como filial da Escola Pueri Domus de São Paulo, o colégio ganhou identidade muito específica a partir de 1984, ano de instauração do Ensino Médio e no qual, com a orientação de Therezinha, tornou-se uma sociedade sem fins lucrativos gerida por seus funcionários.

No texto aqui publicado, Therezinha discute a educação no Brasil, tendo em vista o contexto social, histórico e político do país. Se, por um lado, o texto é datado, na medida em que lida com os problemas de sua própria época, por outro lado também pode ajudar a perceber as permanências que certas discussões têm quando pensamos a educação no Brasil – e os entraves que se colocam para o seu avanço ontem e ainda hoje. Fica aqui o agradecimento à família de Therezinha, em especial à sua filha Bia Lessa, que nos cedeu o original aqui publicado.

Stress Corrosion Cracks in Pipeline Steels
Authors: Mohtadi Bonab Mohammad Ali
Published: April 2020

The demand for pipeline steels has increased in the last several decades since they were able to provide an immune and economical way to carry oil and natural gas over long distances. There are two important damage modes in pipeline steels including stress corrosion cracking (SCC) and hydrogen induced cracking (HIC). The SCC cracks are those cracks which are induced due to the combined effects of a corrosive environment and sustained tensile stress. The present review article is an attempt to highlight important factors affecting the SCC in pipeline steels. Based on a literature survey, it is concluded that many factors, such as microstructure of steel, residual stresses, chemical Composition of steel, applied load, alternating current (AC) current and texture, and grain boundary character affect the SCC crack initiation and propagation in pipeline steels. It is also found that crystallographic texture plays a key role in crack propagation. Grain boundaries associated with {111}//rolling plane, {110}//rolling plane, coincidence site lattice boundaries and low angle grain boundaries are recognized as crack resistant paths while grains with high angle grain boundaries provide easy path for the SCC intergranular crack propagation. Finally, the SCC resistance in pipeline steels is improved by modifying the microstructure of steel or controlling the texture and grain boundary character.

FORMULATION AND EVALUATION OF FLOATING PELLETS OF OMEPRAZOLE BY EXTRUSION SPHERONIZATION METHOD
Authors: Anusha M  , S T Bhagawati  , K Manjunath
Published: April 2020

Objective: The aim of the present study was design, develop and to evaluate a model of floating sustained release pellets formulations for Omeprazole by extrusion and spheronization technique.

Methods: Omeprazole at different drug to polymer ratios were prepared by extrusion and spheronization technique and the release rate of the drug from the pellets was studied. Further, the in-vitro release studies of pellets were carried out in 0.1N HCL for 12 hours. Prepared pellets were subjected to characterization by different techniques such as loose bulk density, tapped bulk density, compressibility index and angle of repose. To optimize the formulation on the basis of acceptable pellet properties friability, drug content, moisture content, and loss on drying and in-vitro drug release tests were done. In addition, the compatibility studies were performed by using FTIR and DSC.

Results: These above studies indicated that the drug release can be modulated by varying the concentration of the polymer. The resulting formulation produced robust pellets with acceptable drug content and low friability. Further, release data was fitted to various mathematical models such as, Higuchi, Korsmeyer-Peppas, First-order, and Zero-order to evaluate the kinetics and mechanism of the drug release. Kinetic modeling of in-vitro dissolution profiles revealed the release mechanism ranges from Quasi-Fickian transport to Anomalous (non-Fickian transport), which was only dependent on the type and amount of polymer used. The drug release of the optimized formulation (F5) follows Zero order kinetics and the mechanism was found to be diffusion controlled. The FTIR and DSC studies reveal that there is no interaction between the drug and the polymer/excipients mixture.

Published: April 2020

现代诗歌是一种特殊的文学样式,有其特有的文体特点,但在现行的语文课堂上,诗歌教学特别是现代诗歌的教学却往往走入一个个误区。很多时候诗歌教学就只停留在“诠释”和“释译”的层次上,甚至有时一首完整的诗歌被肢解得支离破碎,诗歌教学也成了阅读及解题技巧的指导,总给人以隔靴搔痒之感,根本达不到“真正的理解”。我认为,现代诗歌教学的关键还是要抓住诗歌的特点以及诗歌的表现手法,从诵读语言、品味意境、体验情感三方面入手,才能真正感受诗歌的魅力。

Actualmente el uso corriente de plantas medicinales para el tratamiento de las diferentes afecciones se ha incrementado y en la mayoría de los casos se comercializan sin previos estudios de toxicidad. M. oleifera es un árbol distribuido en zonas tropicales y subtropicales, muy utilizado en la medicina tradicional para tratar múltiples afecciones. En el marco del Proyecto de Investigación incentivado 16Q626 “Evaluación de la Genotoxicidad de Extractivos de Especies Medicinales de uso corriente para las afecciones más frecuentes en la Ciudad de Posadas Provincia de Misiones Argentina”, en esta instancia se propuso analizar la genotoxicidad de extractos acuosos de M. oleifera por medio del test de Allium cepa. El experimento consistió en dos etapas, donde además de determinar la concentración que detiene el crecimiento de las raíces un 50% en comparación con los controles y las anomalías macroscópicas, se buscaron los biomarcadores predeterminados de genotoxicidad (cromosomas rezagados, c-mitosis, anafase puente, etc) a concentraciones iguales o superiores a la concentración 50. Las concentraciones más elevadas probadas mostraron mayor inhibición de la mitosis con respecto a los controles, pero no se encontraron efectos genotóxicos, aunque las concentraciones utilizadas en el experimento, no son usuales de M. oleífera en la medicina tradicional.

Published: April 2020

O trabalho a seguir trata sobre a importância das normas relacionadas aos incêndios no Rio de Janeiro. Trata-se de um conhecimento específico aplicado aos projetos de prevenção e combate ao incêndio e pânico, enfatizando-se que, na comunicação de informações a respeito dele, deve-se incentivar o uso de Sprinklers, que, no momento, é o equipamento mais eficaz e seguro para o combate e prevenção de incêndios. O intuito deste artigo é demonstrar que a cultura prevencionista do Rio de Janeiro está paralisada e isso faz com que não alcancemos uma condição de segurança plena no combate ao incêndio e pânico. Por meio de um estudo de caso, será feita uma proposta de melhoria para a prevenção de incêndios no Bloco A da Estácio de Sá (Niterói), reiterando, para tanto, que é necessária a inclusão dessa proposta no projeto do sistema de Sprinklers, colocando, para isso, como prioridade, a segurança dos alunos, funcionários e a integridade do prédio em estudo. No Rio de Janeiro existem diversas orientações a respeito do assunto, mas poucas são conhecidas e divulgadas. Assim, verificamos a defasagem das informações, normas e, também, de projetos. Neste trabalho mostraremos aspectos a respeito do órgão responsável pela aprovação dos projetos de prevenção a incêndios e combate ao pânico no Rio de Janeiro.

Dieser Artikel zielt darauf ab, eine historische Rekonstitution zu erarbeiten, aus der Langzeitserie, der Bildung der brasilianischen Mittelschicht und auch ihrem Archetyp us-Klassenvorurteile. Wir nutzten als Ausgangspunkt für unsere Reflexion die Tatsache, dass Brasilien mehr als dreihundert Jahre Sklaverei lebte, die die Fülle eines rassistischen Imaginären vermachte, was zu voreingenommenen Praktiken führte und zu afronachkommenden Bevölkerungsgruppen eingebürgert wurde, abgesehen davon, dass es sich auf den armen Bürger im Allgemeinen ausgedehnt hatte. Wir versuchen, die untersuchten Objekte auf historistische Weise mit den soziologischen Konzepten der Sozialisation in Beziehung zu setzen, neben der Charakterisierung der bürgerlichen Ideen der Mittelschicht und der brasilianischen Eliten aus der Geschichte der Mentalitäten. Wir beabsichtigen, zu einem besseren Verständnis der Hindernisse beizutragen, die durch das Fehlen von Andersseinpraktiken in den täglichen sozialen Beziehungen entstehen.

Nous essayons de relier d’une manière historiciste les objets étudiés aux concepts sociologiques de la socialisation, en plus de caractériser les idées bourgeoises de la classe moyenne et les élites brésiliennes de l’histoire des mentalités. Nous avons l’intention de contribuer à une meilleure compréhension des obstacles créés par le manque de pratiques d’altérité dans les relations sociales quotidiennes.

Published: April 2020

Ao longo da evolução das relações de trabalho é notável a alteração significativa do papel da mulher no mercado, seja ele formal ou informal. Atualmente, a presença da figura feminina no ambiente de trabalho é de suma importância e o reconhecimento deste fato é o que tem levado a mulher à conquista de seu espaço, mesmo que isso seja de forma gradativa. Embora o número de mulheres nas empresas tenha crescido em grande escala desde o início da inserção da mulher no mercado, no século XIX após a revolução industrial, ainda se enfrenta obstáculos e paradigmas que serão ressaltados neste texto.

Authors: Viola José Raphael , Scatolin Henrique Guilherme
Published: April 2020

O presente trabalho tem por objetivo pesquisar sobre os elementos geradores de satisfação e insatisfação no âmbito do trabalho público, para desta forma identificar os elementos que levam os servidores a atingir tais estados emocionais. Desta forma pretende-se evidenciar se é possível obter satisfação trabalhando em órgãos públicos, ou se estes são geradores de insatisfação devido aos seus métodos organizacionais. Este trabalho possui os servidores públicos como foco de pesquisa, pois estes trabalhadores não partilham dos mesmos elementos funcionais da iniciativa privada. Para a realização da pesquisa foi utilizado o método de revisão bibliográfica, qualitativa e exploratória, buscando dados em artigos publicados na base de dados online, Scielo, com os descritores “trabalho e satisfação” e “trabalho e insatisfação”, sendo atribuídos como fatores de inclusão os artigos com menos de cinco anos de publicação e disponíveis na integra em português. Com este método se teve o intuito de compreender o que vem sendo publicado sobre satisfação e insatisfação e, utilizar estas informações buscando atingir a problemática desta pesquisa, de forma a desenvolver a aproximação com o tema proposto e facilitar a reflexão sobre as instituições públicas e, o como estas afetam a vida laboral de seus servidores. Sendo, por fim, possível concluir que a satisfação e insatisfação são elementos subjetivos que podem se apresentar por diferentes fatores em diferentes indivíduos, porém se demonstra como principal fator de satisfação o reconhecimentos e de insatisfação o salário e falta de condições favoráveis para a realização do trabalho.

La classe media brasiliana e l’archetipo del pregiudizio di classe
Authors: Giesbrecht Daniel Florence
Published: April 2020

Questo articolo ha lo scopo di elaborare una ricostituzione storica, dal seriale a lungo termine, la formazione della classe media brasiliana e anche il suo archetipo di pregiudizio di classe. Abbiamo usato come punto di partenza per la nostra riflessione il fatto che il Brasile ha vissuto più di trecento anni di schiavitù, che ha fatto la profusione di un immaginario razzista, con conseguente pregiudizio e naturalizzato alle popolazioni afrodiscendenti, oltre ad essersi esteso al povero cittadino, in generale. Cerchiamo di mettere in relazione in modo storicista gli oggetti studiati ai concetti sociologici della socializzazione, oltre a caratterizzare le idee borghesi della classe media e delle élite brasiliane dalla storia delle mentalità. Intendiamo contribuire a una migliore comprensione degli ostacoli creati dalla mancanza di pratiche di alterità nelle relazioni sociali quotidiane.

Parole chiave: Classe sociale, pregiudizio, schiavitù, esclusione sociale, alterità.
