RESISTÊNCIA A CORROSÃO EM DIFERENTES TRATAMENTOS DE SUPERFÍCIE SOBRE LIGAS DE ZINCO UTILIZADOS EM METAIS SANITÁRIOS
Authors: Arnold Suzan , Kunst Sandra Raquel , Fuhr Luciane Taís , Oliveira Cláudia Trindade
Published: December 2019

Entre as ligas não ferrosas, as ligas de zamac são as mais utilizadas para a fundição e vêm sendo aplicadas na substituição de peças de latão, utilizadas industrialmente em metais sanitários. O zamac apresenta propriedades mecânicas semelhantes às do latão, porém com custo inferior. Entretanto, a alta porosidade destas ligas, impede que tratamentos superficiais garantam bom acabamento e resistência à corrosão. Visando melhorar o desempenho, frente à corrosão de peças de zamac, o objetivo do presente trabalho é avaliar o processo de diferentes tratamentos de superfície dos metais sanitários produzidos em zamac. As amostras foram injetadas sobre pressão e submetidas a diferentes tratamentos superficiais (tratamento mecânico, tratamento químico, cobre alcalino, cobre ácido, níquel, cromo). Os corpos de prova foram expostos a um meio agressivo, por meio de nevoa salina a fim de analisar a resistência à corrosão das peças, além de análises de polarização, metalografia e microdureza. Observou-se que a maior incidência de corrosão ocorreu nas partes de injeção e solda da peça, as amostras tratadas com níquel e cromo demonstraram o melhor desemprenho frente a resistência a corrosão.Palavras-chave: Zamac. Metais sanitários. Corrosão.ABSTRACTAmong the non ferrous alloys, zamak are the most used for casting and have been applied to substitute brass parts, industrially utilized in sanitary metals. The zamak presents mechanical properties similar to brass, however with lower cost. Meanwhile, the high porosity of these alloys hinders the superficial treatments ensure good finishing and corrosion resistance. Aiming to improve the performance against corrosion of zamak parts, this work evaluates the process of different superficial treatments of sanitary metals produced with zamak. The samples were injected under pressure and submitted to different superficial treatments (mechanical, chemical, alkaline copper, acid copper, nickel and chromium). The specimens were exposed to an aggressive medium through salt spray test to evaluate the corrosion resistance, and the following analysis: polarization, metallography and microhardness. It was observed that the higher corrosion incidence occurred on the injection and weld regions. The samples treated with nickel and chromium demonstrated better performance of corrosion resistance.

O desenvolvimento sustentável e a erradicação da pobreza são apontados pela Organização das Nações Unidas como problemas a serem superados até 2030, sendo elencados 17 objetivos visando o desenvolvimento sustentável. Nesse artigo destaca-se o terceiro Objetivo do Desenvolvimento Sustentável (ODS), voltado para a saúde e a promoção do bem-estar para todos, em todas as idades, tendo como prioridade reduzir a taxa de mortalidade neonatal, infantil e materna, bem como as mortes por causas evitáveis de 0 a 75 anos. Os dados analisados mostram-se na contramão aos ODS 3 - saúde, visto que têm aumentado o número de mortes nos anos avaliados, sendo que em 2016 alcançaram os maiores índices do período analisado. Os desafios propostos pelos ODS vão além de contemplar questões que afetam as pessoas, o planeta, a prosperidade e a paz. Os ODS reconhecem que acabar com a pobreza deve acompanhar as estratégias que criam o crescimento econômico e abordam uma série de necessidades sociais, incluindo educação, saúde, proteção social e oportunidades de emprego. Essas ações colocam o Enfermeiro diante de desafios práticos que ultrapassa os âmbitos do hospital e da Unidade Básica de Saúde, exercendo um papel que permita participar das decisões políticas e de gestão dos sistemas de saúde, chamando-os para um papel de liderança e de ações intersetoriais.

A busca por um sorriso harmônico é o desejo da maior parte da população. A estética encontra-se atualmente frequente e comum na prática clínica diária. As principais alterações são forma dental, tamanho, cor e posição. Com o desenvolvimento da odontologia adesiva e dos materiais estéticos, a restauração direta com compósito, através da mínima invasão dos tecidos dentários hígidos vem sendo utilizada. O objetivo desse trabalho é apresentar um caso clínico em que se optou, como plano de tratamento, pelo clareamento dental de consultório, seguido da confecção de encerramento para planejamento do caso, com mock-up motivacional e fechamento de diastemas com restaurações em resina composta direta, seguindo a proporção áurea. A realização do clareamento dental possibilitou a homogeneização de cor do esmalte dental e das manchas de fluorose. O fechamento de diastemas utilizando o enceramento diagnóstico e a grade de Levin facilitou a reprodução do planejamento durante a execução das restaurações. As restaurações diretas são uma alternativa viável para reanatomização dental, pois torna o tratamento de resultados rápidos, de baixo custo e de estética satisfatória.

PT. Este artigo busca abordar os modos como o medo do outro e um desejo de exclusão se articulam no âmbito da atividade jornalística. Tendo como base teórica as discussões sobre o medo (Delumeau, 1996; Matheus, 2011) e o outro, este último a partir da perspectiva da alteridade (Levinas, 1982, 2005), o objetivo desse texto é tensionar as formas como um medo que decai sobre sujeitos os transforma em corpos a serem exterminados. Para tanto, propomos uma leitura de matérias que tratam de assassinatos de travestis e transexuais no estado brasileiro de Minas Gerais, na procura de pistas que contribuam para a compreensão da forma como o medo presente nessas produções e em articulação com a vida social movimentam sentidos acerca de um desejo de exclusão desse outro.

Starting from a theoretical discussion about fear (Delumeau, 1996; Matheus, 2011) and the other, from the perspective of otherness (Levinas, 1982, 2005), the purpose of this text is to problematize the ways in which fear that debases others turns them into bodies to be exterminated. In order to do so, we propose a reading of news that deals with murders of trans people in Minas Gerais, in search of clues to help understand how the fear present in these journalistic productions and its relationship with social life can shape the desire to exclude the other.

Avoiding faradaic side reactions during the operation of electrochemical devices is important to enhance the device stability, to achieve low power consumption, and to prevent the formation of reactive side‑products. This is particularly important for bioelectronic devices which are designed to operate in biological systems. While redox‑active materials based on conducting and semiconducting polymers represent an exciting class of materials for bioelectronic devices, they are susceptible to electrochemical side‑reactions with molecular oxygen during device operation. We show that this electrochemical side reaction yields hydrogen peroxide (H2O2), a reactive side‑product, which may be harmful to the local biological environment and may also accelerate device degradation. We report a design strategy for the development of redox-active organic semiconductors based on donor-acceptor copolymers that prevent the formation of H2O2 during device operation. This study elucidates the previously overlooked side-reactions between redox-active conjugated polymers and molecular oxygen in electrochemical devices for bioelectronics, which is critical for the operation of electrolyte‑gated devices in application-relevant environments.
What Makes an Explosion Happen?
Authors: Sun Chang
Published: December 2019

The combination of intermolecular hydrogen bond (X:H–Y) tension and the anti-HB (H↔H) or super-HB (X⇔Y) compression not only stabilizes the structure but also stores energy by shortening the intramolecular covalent bonds. The X:H tension constrains and the X⇔Y compression fosters explosion.
Efficient Multi-Configurational Wavefunction Method with Dynamical Correlation Using Non-Orthogonal Configuration Interaction Singles and Doubles (NOCISD)
Authors: Nite Jacob , Jimenez-Hoyos Carlos A.
Published: December 2019

It is well known that inclusion of dynamical correlation is needed in order to reach quantitative agreement with experiment for molecular systems with multi-reference character. In this work, we start from a non-orthogonal configuration interaction (NOCI) framework that accounts for the static correlation and incorporate dynamical correlation by including singles and doubles excitations out of each reference determinant resulting in a NOCISD wavefunction. The equations defining the NOCISD wavefunction commonly require the solution a poorly condition generalized eigenvalue problem, which we avoid by projecting the equations to a small dimension space defined by the CISD eigenvectors of each reference determinant. We show that NOCISD results are in good qualitative agreement with other state-of-the-art method for challenging problems such as the electron transfer in the ethylene dimer radical cation and LiF, as well as the description of the Jahn-Teller distortion in the cyclopentadienyl and nitrogen trioxide radicals.
Effective Plasmonic Coupling and Propagation Facilitates Ultrasensitive and Remote Sensing Using Surface Enhanced Raman Spectroscopy

Published: December 2019

Surface-enhanced Raman spectroscopy (SERS) is a sensitive technique for the detection of analytes through light scattering that is enhanced by chemical and electromagnetic effects through interactions on surfaces, particularly in nano-gaps. Herein we show that dissolved oxygen is the strongest attenuator of the SERS response in aqueous solution and its removal by chemical means can lower the detection limit by 109–1010 times, to achieve unprecedented sensitivity, i.e., detection of a single molecule in ~300 µL of sample solution. It also enables remote detection of the analyte outside of the field of view of the incident laser beam, e.g., over a distance of 1 m, which we propose is due to the coupling of the plasmonic field within and between nanoparticle aggregates, allowing for signal transmission throughout the sample volume.
Phase-Segregation and Photothermal Remixing of Mixed-Halide Lead Perovskites
Authors: Vicente Juvinch R. , Chen Jixin
Published: December 2019

Mixed-halide lead perovskites (MHPs) are promising materials for photovoltaics and optoelectronics due to their highly tunable bandgaps. However, they phase-segregate under continuous illumination and/or electric field, whose mechanism is still under debate. Herein, we systematically measure the phase-segregation behavior of CH3NH3Pb(BrxI1-x)3 MHPs as a function of excitation intensity and nominal halide ratio by in situ photoluminescence micro-spectroscopy. We encapsulate the MHPs with a layer of polystyrene polymer film to isolate them from the effects of the immediate atmosphere. Under this passivated condition, the phase segregation of the MHPs is very different from those without polymer passivation reported in the literature. The initial phase segregation to I-rich and Br-rich phase is observed followed by the formation of a new mixed-halide phase within several seconds that has not been reported before. We observe that the photothermal effect is amplified at the small-size I-rich domains which significantly changes the local phase segregation in the otherwise uniform film as early as milliseconds after illumination.
A Photoactivable Formaldehyde Donor with Fluorescence Monitoring Reveals Threshold to Arrest Cell Migration
Authors: Smaga Lukas P , Pino Nicholas W , Ibarra Gabriela E , Krishnamurthy Vishnu , Chan Jefferson
Published: December 2019

Controlled light-mediated delivery of biological analytes enables the investigation of highly reactivity molecules within cellular systems. As many biological effects are concentration dependent, it is critical to determine the location, time, and quantity of analyte donation. In this work, we have developed the first photoactivatable donor for formaldehyde (FA). Our optimized photoactivatable donor, photoFAD-3, is equipped with a fluorescence readout that enables monitoring of FA release with a concomitant 139-fold fluorescence enhancement. Tuning of photostability and cellular retention enabled quantification of intracellular FA release through cell lysate calibration. Application of photoFAD-3 uncovered the concentration range necessary for arresting wound healing in live cells. This marks the first report where a photoactivatable donor for any analyte has been used to quantify intracellular release.
Religious Symbols in Public Schools as Teachable Controversies in Religious Education
Authors: Moe Christian
Published: December 2019

This focus issue of CEPS Journal raises two topics usually treated separately, Religious Education and the use of religious symbols in public schools. Both involve the challenge of applying liberal democratic principles of secularism and pluralism in a school setting and refract policies on religion under conditions of globalisation, modernisation and migration. I take this situation as a teachable moment and argue that it illustrates the potential of a particular kind of Religious Education, based on the scientific Study of Religion, for making sense of current debates in Europe, including the debate on religious education itself. However, this requires maintaining a spirit of free, unbiased comparative enquiry that may clash with political attempts to instrumentalise the subject as a means of integrating minority students into a value system.

Published: December 2019

A Cota de Reserva Ambiental (CRA) visa cotizar o excedente legal de florestas e vegetações tuteladas juridicamente, para poder ser uma alternativa no procedimento de compensação ambiental para a regularização de propriedade rural. No entanto, a normatização desse instrumento no vigente Código Florestal possui críticas, que culminaram na apreciação pelo Supremo Tribunal Federal de forma (in)direta nas Ações Diretas de Inconstitucionalidade 4901, 4902, 4903 e 4937 e na Ação Declaratória de Constitucionalidade 42. Neste contexto, a CRA pode ser considerada um instrumento econômico e socioambiental promissor à proteção do meio ambiente saudável intergeracional, na atual configuração legislativa em que foi confirmada a sua constitucionalidade pelo Supremo Tribunal Federal? Com o objetivo precípuo de analisar as principais discussões atinentes à CRA nas ações diretas, o presente estudo traz como conclusão a necessidade de aprimoramento multidisciplinar ao instituto da CRA, para que realmente apresente resultados positivos à sociedade e ao meio ambiente ecológico.

Así, el estudio reciente de Carrillo-Punina confirma la relación entre las tipologías culturales orientadas a los resultados con al-gunas variables del desempeño financiero en el sector de cooperativas de ahorro y crédito ecuatoriano. De este modo, continuando con el estudio, se desarrolla la investigación de tipología cultural en una cooperativa de ahorro y crédito del mismo segmento que se caracteriza por la amplia cobertura geográfica. Se aplica el cuestionario de Felcman y Góngora a una muestra de 377 funcionarios de la cooperativa que representa el 76% de la población y fiabilidad Alpha de Cronbach de 0,978. Los resultados indican el predominio de la cultura exigente, seguido de la tipología apática; sin embargo, el sector presenta el dominio cultural exigente e integrativo lo que conduce al planteamiento de una nueva hipótesis de investigación: las cooperativas con fortaleza financiera tipo A presentan tipologías culturales exigentes e integrativas y, aquellas con fortaleza financiera tipo b, se identifican con tipologías exigentes o integrativas y apáticas.

El presente artículo define el constructo de pobreza y vulnerabilidad, las razones por las cuales la pobreza y la vul-nerabilidad se anidaron en latinoamérica y, desde luego, en México. Del mismo modo, la investigación evidencia los niveles de pobreza existentes en México en la actualidad, así como sus causas, particularmente en el municipio de Tekax, estado de Yucatán. Posteriormente, se hace una revisión y análisis sobre diferentes casos de éxito en combate a la pobreza, desarrollo económico y social por medio de estrategias de desarrollo de capital humano, intelectual y social, en países cuyas características socioeconómicas eran similares a las condiciones de vida en México y el estado de Yucatán. De esta manera, se busca comprender por qué otras economías (principalmente las del este asiático) han logrado tener grandes avances en materia de desarrollo económico y social, mientras que México, a pesar de su gran capacidad económica, no ha podido de alcanzar los mismos resultados en cuanto a reducción de pobreza y vulnerabilidad, desarrollo económico y social. Para finalizar, con conclusiones y recomen-daciones sobre directrices complementarias que la sociedad yucateca podría implementar, para mejorar los niveles de bienestar de la población en Tekax.

Purpose: This research aimed is to design a sociopreneurship (Social Entrepreneurship) business incubator system by integrating the Information Technology Infrastructure Library (ITIL) features as a supporting tool in managing business incubator. With the sociopreneurship business incubator design is expected to help overcome social problems that occur in the community.

Design/methodology/approach: This research is a qualitative research using the Human Centered Design (HCD) method. The stages in this HCD method are Hear, Create and Delivery. However, because the purpose of this study is to design, the stages that are passed are up to the Create stage.

Findings: Based on the research, business incubators design were produced with 7 business fields, 5 service fields, 2 phases, namely co worker space and event space with details: 5 programs and activities in the co worker space phase and 2 programs and activities in the event space phase. Business incubator system also designed by integrating the Information Technology Infrastructure Library (ITIL) features as a supporting tool in managing business incubator.

Research limitations/implications: This research is limited to the design so that the 3 stages of the HCD method are used only up to the second stage, namely the Create stage.

Practical implications: In this research, it seeks to accommodate the community's needs for a business field so that services and programs of business incubator can be obtained that are in accordance with the needs of the community. This study also seeks to present a business incubator that is tailored to the needs of the community so that the community does not only have economic independence but can be mutually transmitted and sustainable with other communities (sociopreneurship) and by utilizing information technology.

Originality/value: In this study the researchers collected, identified and interpreted the data that had been obtained. For this purpose, a literature review and approach to the HCD method are used through interview techniques by approaching the community and analyzing their needs in order to produce an analysis of results accordingly.

The purpose of this study is to determine the effect of promotion on sales at PT. 3M Indonesia Surabaya Branch. The sample used in this study amounted to 30 consumers. The analysis technique used is simple linear regression analysis and simple determination. In order to test the effect of partial and simultaneous of these independent variables, the researcher conducted a partial test (t test) and simultaneous test (F test). The variables used are  sales (Y) and promotion (X) and data analysis tool using simple regression formula, correlation coefficient and determination. The results of the study show that the regression equation is Y = 17,020 + 0,320 (x) with  Y value of 17,020 which means that if the promotion (X) value is 0, then sales (Y) is 17,020. And the promotion variable regression coefficient (X) is 0.320. This means that if promotion (X) increases by 1 unit, then an increase in sales (Y) will increase by 0.320. Based on the results of the correlation coefficient test shows a positive value, meaning that Ho is rejected and Ha is accepted, it can be concluded that there is a significant effect between promotion and sales at PT. 3 M Indonesia Surabaya Branch.
What makes students speak Japanese in immersion programs?
Authors: Katayama Kumiko , Hashimoto Kayoko
Published: December 2019

Language immersion programs, which are a form of bilingual education, are shaped by multiple factors, including the specific characteristics of the region, the language, the community and the learners, as well as national and regional policies on language education. While the underdeveloped production skills of immersion students have been identified as the product of teacher-centred and controlled learning environments, it is not known what role background or heritage language students play in the Australian one-way immersion context, where their presence itself potentially enhances the speaking environment. This paper, based on a project on developing speaking strategies for a Japanese immersion program in Australia, argues that the speaking performance of students in immersion classes is also determined by other factors, such as peer interactions with background students, whose treatment in education systems in Australia remains ambiguous, reflecting the history of separation between foreign language education in schools and the maintenance of mother tongues in the community. By applying Critical Discourse Analysis (CDA), this paper analyses language policy and educational documents and discusses how the language performance of individual learners could be influenced not only by the curriculum but also by policy makers’ improved understanding of individual learners with diverse linguistic backgrounds within schools.
The effect of cohesive features in integrated and independent L2 writing quality and text classification
Authors: Tywoniw Rurik , Crossley Scott
Published: December 2019

Cohesion features were calculated for a corpus of 960 essays by 480 test-takers from the Test of English as a Foreign Language (TOEFL) in order to examine differences in the use of cohesion devices between integrated (source-based) writing and independent writing samples. Cohesion indices were measured using an automated textual analysis tool, the Tool for the Automatic Assessment of Cohesion (TAACO). A discriminant function analysis correctly classified essays as either integrated or independent in 92.3 per cent of cases. Integrated writing was marked by higher use of specific connectives and greater lexical overlap of content words between textual units, whereas independent writing was marked by greater lexical overlap of function words, especially pronouns. Regression analyses found that cohesive indices which distinguish tasks predict writing quality judgments more strongly in independent writing. However, the strongest predictor of human judgments was the same for both tasks: lexical overlap of function words. The findings demonstrate that text cohesion is a multidimensional construct shaped by the writing task, yet the measures of cohesion which affect human judgments of writing quality are not entirely different across tasks. These analyses allow us to better understand cohesive features in writing tasks and implications for automated writing assessment.

The territorial waters of Jayapura City, especially the waters of North Jayapura and South Jayapura are the centers of capture fisheries activities of big pelagic species, namely tuna and skipjack tuna, which need to be utilized to provide welfare for the community, especially fishermen in a sustainable manner. For this reason, this study was conducted to analyze the level of utilization of big pelagic fisheries resources and analyze the welfare level of big pelagic fishermen households in Jayapura city waters. Primary data collection is done through interviews with respondents who are randomly selected. Utilization level analysis was carried out using multispecies bioeconomic analysis and analysis of fisherman welfare levels was carried out using the criteria of the poverty line set by the Central Bureau of Statistics. The results showed the actual utilization rates of tuna and skipjack fisheries resources in the waters of Jayapura City are still in the continuous production of MSY and MEY. Nevertheless, the utilization of these big pelagic fisheries resources needs to be supported by economic institutions that can better distribute their benefits, especially to fishermen. This is because based on the survey conducted; most of the household welfare of the big pelagic fishermen tuna and cakalang in the waters of Jayapura City are still classified as not prosperous.

The observation of smoke because of land and forest fires in some regions in Indonesia mostly use the composite image visually. This study aims to develop the detection model of forest and land fire smoke using a digital analysis, which will be faster in supporting spatial information on emergency response in monitoring forest and land fire smoke. The method used is multi-threshold method and compare it with the existing model that is by modification of method Li et al. (2015). The data used is Suomi NPP-VIIRS satellite imagery. The results concluded that the VIIRS image can be used to detect the smoke and smoke distribution of forest fire and digital smoke. The multi-threshold model uses reflectance data obtained from the M4 visible channel, and the brightness temperature data obtained from the LWIR VIIRS M14 channel, with an average accuracy of 82.2% with a Commision error of 9.8% and an Ommision error of 10%. While the model of modification Li is based only on reflectance of visible-channel data i.e. channel M1, M2, M3, and SWIR VIIRS M11 channel, which has an average accuracy of 72.3% with a Commision error of 0.3% and an Ommision error of 27.4%. The multi-threshold model is a model that has the potential to be applied to detect forest and land fire smoke.
