Diante da crescente consciência ambiental relacionada à limitação dos recursos naturais e da necessidade de gerir resíduos produzidos pela atividade da construção civil, se faz necessário elencar novas alternativas para minimização de impactos gerados. Esse trabalho apresenta uma revisão narrativa sobre o uso de resíduos na fabricação de materiais alternativos para construção civil. Foram realizadas buscas em base de dados, como: SciELO e no portal Google Acadêmico, com os termos resíduos da construção, reaproveitamento e sustentabilidade no período compreendido entre 2017 e 2023. Os resultados mostraram que o setor da construção civil apresenta atividades com potencial de reaproveitamento de resíduos oriundos do ciclo e, sobretudo, na utilização de novos materiais. Conclui-se que a incorporação de resíduos da construção é uma solução técnica possível, com grande capacidade de expansão e aplicabilidade em materiais.

Authors: Souza TO , Oliveira CO , Santos CC , Batalha EMSS
Published: May 2023

Introdução: Os acidentes de trabalho com exposição a material biológico ocorrem devido a um conjunto de fatores, sejam eles organizacionais, ambientais ou individuais. Esse tipo de acidente pode trazer uma mudança súbita na vida dos profissionais acometidos, bem como, em casos mais extremos, a evolução à óbito. Objetivo: Analisar o perfil dos acidentes de trabalho com exposição a material biológico em profissionais de saúde notificados para a Diretoria de Vigilância e Atenção à Saúde do Trabalhador do Estado da Bahia (DIVAST- BA), no período de 2012 a 2021. Método: Trata-se de um estudo quantitativo, descritivo, com dados secundários. A coleta de dados e análise dos dados ocorreu entre outubro de 2021 a fevereiro de 2022 através da plataforma SINAN NET. Foram extraídas as informações acerca das características sociodemográficas e laborais dos profissionais de saúde acometidos pelos acidentes, bem como os principais tipos de acidentes, as macrorregiões notificadoras, as circunstâncias e a evolução dos casos. Resultados: Foram analisados 17.341 notificações, a maioria dos profissionais que sofreram acidente com exposição a material biológico eram do sexo feminino (84,40%), na faixa etária de 30 a 39 anos (38,53%), declararam – se como pardas (54,60%). Os técnicos de enfermagem foram os profissionais de saúde que mais sofreram esse tipo de acidente (63,78%). O sangue foi o principal material biológico envolvido nos acidentes (23,09%) e a administração medicamentosa foi o principal procedimento em que houve exposição a material biológico. Os tipos de exposição mais frequentes foram os percutâneos (70,91%) e em pele não íntegra (72,55%). A macrorregião de saúde que mais notificou foi a Leste (37,4%). A maior parte das notificações de evolução estavam ignoradas ou em branco (52,64%); seguida pelos profissionais que evoluíram com alta do paciente fonte negativo (30,49%) e alta sem conversão sorológica (12,06%). Considerações finais: Através dos resultados obtidos neste estudo, pode-se verificar importância do risco biológico para os profissionais de saúde, uma vez que os acidentes com exposição a material biológico ainda se constituem um problema de saúde pública. Ações diretivas da saúde devem ser pautadas no treinamento, capacitação e sensibilização dos profissionais de saúde e os riscos e fatores devem ser identificados a fim de reduzi-los. Esses resultados poderão fomentar ações que estimulem e ampliem a atuação da vigilância e da assistência à saúde do trabalhador, especialmente voltadas para os profissionais mais atingidos pelos acidentes e para as circunstâncias de maior risco.

No campo da saúde pública, o planejamento estratégico apoia-se nas teorias da situação, da produção social e da ação interativa, com as principais características de ser flexível e interativo. Uma gestão eficiente potencializa o cumprimento de sua missão. A partir do reconhecimento dos problemas e dos fatores que interferem na situação que se deseja alterar, é necessário estabelecer quais serão os caminhos a serem seguidos para solução de problemas e como monitorá-los ao longo do tempo. Nos últimos anos, estudos registaram progressos significativos na realização de intervenções, na comunidade, destinadas a atingir objetivos relacionados com a melhoria da saúde. Portanto, o papel dos instrumentos de planejamento como ferramenta de apoio à gestão e também como instrumento para comunicação das ações desenvolvidas são essenciais para a efetividade e qualidade de uma atividade/ projeto.

O processo de humanização é possibilitado pelo acesso, compreensão e transformação do conhecimento já acumulado pela humanidade, nesse sentido, a cultura escrita é compreendida como importante instrumento mediador do sujeito em formação com esse conhecimento, entretanto, o senso comum insiste na ideia de que o brasileiro têm lido menos nos últimos tempos. Mediante tais processos, o presente artigo visa possibilitar algumas reflexões com base em dados quantificados de aquisição de livros na atualidade e apresentar o processo de virtualização da cultura escrita, o que possibilita maior democratização e socialização dos conhecimentos, mas também permite a criação de redes de compartilhamento de notícias falsas.
DA RETÓRICA E DA PROVA NA HISTORIOGRAFIA CONTEMPORÂNEA: EMBATES
Authors: Aranha Gervácio Batista
Published: May 2023

O objetivo deste trabalho é demonstrar que a escrita da história, em seu vínculo com os chamados paradigmas emergentes desde os acertos de contas epistemológicos, políticos e/ou éticos de maio de 68 e anos subsequentes, há sido marcada por profundas tensões no tocante aos modelos miméticos que podem lhes servir de referência, na esteira dos quais vieram à tona concepções de história orientadas por descontinuidades tão somente e concepções de história para quem descontinuidades e continuidades se apresentam como faces de uma mesma moeda. Com isto, a escrita da história vem sendo informada, de um lado, pelos que, assumindo posturas antimiméticas, apostam alto no esvaziamento do referente e, do outro, pelos que continuam alinhados com o campo da mímesis, o qual se caracteriza por vínculos indissolúveis entre linguagem e mundo vivido. O pressuposto aqui é que nenhuma escrita da história é capaz de vingar caso não esteja ancorada em sólidas evidências empíricas com vistas ao estudo de referentes passados ou presentes.

O ambiente escolar é um local com grande número de circulação de pessoas, sendo esse local alvo do monitoramento e controle pela Vigilância Sanitária Ambiental para o consumo humano de água. Essa água precisa estar dentro dos padrões de potabilidade seguindo a legislação vigente e livre de contaminantes físicos, químicos e/ou biológicos. Mesmo com o tratamento adequado, a água pode apresentar riscos durante sua distribuição. Ness contexto o objetivo do presente trabalho foi avaliar a qualidade da água para consumo humano em escolas públicas, localizadas no município de São Luís. Para tanto foram amostradas sete escolas públicas do ensino médio, com coleta de água para análise laboratorial e observações in loco. Os parâmetros analisados foram pH, cloreto, temperatura, condutividade, dureza total, coliformes totais e Eschirichia coli. As análises de pH, temperatura e condutividade foram determinados in situ com o uso de equipamentos portáteis enquanto os demais parâmetros foram determinados no Laboratório Central de Saúde Pública do Maranhão. Os resultados demonstraram que a água que abastece cinco (71,2%) das sete escolas amostradas estão de acordo com a legislação vigente brasileira, enquadrando-se dentro do padrão de potabilidade preconizado pela Portaria do Ministério da Saúde nº 888/21.
DISFUNÇÃO NEUROBIOLÓGICA OU DEFICIÊNCIA INTELECTUAL: DO QUE ESTAMOS FALANDO?
Authors: Martins Carlos Eduardo , Nogueira Martins Vanessa de Cássia
Published: May 2023

Apesar de alguns avanços e aprimoramentos na área da educação, acerca de metodologias, conteúdos e práticas, ainda é possível perceber o desconhecimento das várias diferenças existentes entre algumas dificuldades de aprendizagem e como (e porque) elas ocorrem. Esta desinformação, em muitos casos, conduzem o aluno à uma metodologia diferente e inadequada, o que lhe poderá lhe causar consequências desagradáveis ao seu aprendizado. Também se percebe que nas formações acadêmicas, a carga horária da disciplina que tratará a respeito do assunto é ínfima, para um conteúdo tão relevante, complexo e robusto. A diversidade de alunos obriga o professor a estar em constante aprimoramento e atualização de suas informações, no entanto, tal profissional também esbarra em alguns problemas de gestão escolar (falta de oferta em cursos de capacitação, aperfeiçoamento, especialização, carga horária exaustiva, número desproporcional de alunos por turma, currículos por vezes desatualizado, livros com edições antigas). Por conta desse desconhecimento acadêmico, alunos com deficiência intelectual são atendidos de maneira incorreta como se tivessem uma disfunção neurobiológica, e vice-versa.
Improvement of Plate-Fin Heat Exchanger Performance with Assistance of Various Types of Vortex Generator
Authors: Ali Sabri Abbas  , Ayad Ali Mohammed
Published: May 2023

A 3-dimensional incompressible laminar flow and heat-transfer in a plate-fin heat exchanger (PFHE) where investigated numerically in this article. The influence of mounting a longitudinal vortex generator (LVG) on the offset rectangular-triangular fin (ORT) in the PFHE, on thermal and hydro-dynamic fields are presented. The novelty of this study is by attaching a LVG to an offset strip fin (OSF) surface. The cases of study for the PFHE are established, by using a built-in rectangular winglet pair type RWP longitudinal vortex generator carried out and fitted on this fin to improve the convective heat transfer of the (ORT) fin while minimizing pressure loss. The upper and lower plates are exposed to constant heat flux and the working fluid is air where chosen under a laminar range of RE (600 to 1400). The laminar flow and heat-transfer are governed by continuity, momentum and energy equations. ANSYS FLUENT (2021 R1) is used to get the numerical results, based on the finite volume method. The performance of the VG is assessed for an optimum winglet attack angle (45°), as well as by modifying the geometrical size parameters, namely the height and placement (L) of the RWP LVG. The result shows that the Nusselt number reaches its optimum enhancement values by using a common flow up CFU built-in rectangular winglet pair type RWP VG with a height and entrance length of (h=1.25mm, L=0.5mm), by 22.23% as compared with base case configuration (ORT). Finally, a two more LVG are tested with the optimum conditions of the RWP, which they are a delta winglet pair (DWP) and trapezoidal winglet pair (TWP). In addition, the temperature fields for the primary and secondary flows were shown in contour and streamline diagrams
Study on the Effects of Individual Pitot Tube Inlet of a Bladeless Tesla Microturbine using Numerical Analysis

Published: May 2023

In this paper, a comprehensive numerical analysis of a bladeless Tesla microturbine is presented. Various studies on the effects of Tesla design parameters have shown promising results. However, the limitations associated with the inherent nozzle design have often highlighted the low efficiency of the turbine. Therefore, the study was carried out using computational fluid dynamics (CFD) to demonstrate the efficiency of the turbine as a function of the performance of different openings of the inlet nozzles, i.e., as 1-opening and individual pitot tube opening. In this work, a validation study was performed with the existing manuscript before further investigating the effects of the different openings of the inlet nozzles. The results show that the configuration of 4 inlets with 4 openings (4i4o) results in higher velocity and pressure distribution compared to 4 inlets with 1 opening (4i1o). Consequently, 4i4o obtained a higher torque value compared to 4i1o with a difference of 10%. Hence, the thrust and efficiency values for the 4i40 were 33.69% and 34.30%, respectively, higher compared to the 4i1o. The performance of the Tesla turbine with the specified optimal configuration increased very significantly compared to the previous research studies. It can be concluded that the introduction of the functional theory of the ‘pitot-tube’, which considers the gaps individually by having a separate inlet for each of them, had a great impact on the performance of Tesla turbine.

At the end of 2019, the COVID-19 virus began to appear and quickly spread throughout the world. It transmits the infection to the respiratory tract by the transmission of pathogens within bioaerosols during speaking, coughing, and sneezing. Therefore, understanding the dynamics of aerosols plays an important role in developing mitigation strategies against droplet infections. Computational modeling, using fluid and computational dynamics, has become a useful feature in studying and visualizing the diffusion of micro-droplets that are difficult to reach using experimental methods. Through this study, the effects of using cloth face masks and social distancing, both recommended by the World Health Organization to the general public to avoid rapid transmission of COVID-19, were determined. This study made a comparison between different structural masks and the difference between social distancing with different porous masks at the droplet diameter during breathing from 0.5 µm to 2.5 µm. The results showed the effectiveness of wearing masks in reducing the risk of infection transmission. Also, with lower mask porosity, lower air permeability means higher filtration efficiency, trapping airborne particles more effectively, especially for small infection-carrying particle sizes, and, therefore, lowering the required social distancing. From the comparison, it is concluded that sample 6 has the highest efficiency of 82.9% compared to other samples (1, 2, 3, 4, and 5), which have efficiencies of 77.1%, 77.1%, 74.3%, 80.0%, and 65.7%, respectively

Published: May 2023

Purpose – find differences in the core principles of implementation of CSR (Corporate Social Responsibility) practices in subsidiaries of foreign multinationals in Slovak and Czech Republic, two similar yet different countries. Research methodology – the questionnaire was distributed to local daughter companies of foreign multinational enterprises selected on the basis of stratified randomization. The sample: 360 enterprises (180 from each country). Mann‐Whitney U Test was used for the analysis (non-normally distributed data) of the differences between Slovak and Czech companies in their CSR implementation. Findings – differences among the two countries in the implementation of CSR exist in few factors due to their joint history. Research limitations – the representativeness of companies connected with foreign mother companies in the two countries cannot be computed: no data are available. To overcome this issue, the same number of monitored entities was analysed to so as to make further statistical analysis possible. Practical implications – the results can be used by business entities, which may benefit from comparing themselves against other players on the market or against the average situation on the monitored markets. Moreover, teaching future managers and promoters CSR is of significant importance. Originality/Value – the work sheds lights on CSR practices in Czechia and Slovakia, two countries in which there is a lack of studies on the topic of CSR.
Vibrational, Rotational, and Electronic Spectroscopy for Possible Interstellar Detection of AlNH2 and HAlNH
Authors: Trabelsi Tarek , Esposito Vincent J. , Francisco Joseph S.
Published: May 2023

We obtained accurate vibrational frequencies, rotational constants, and vertical transition energy for AlNH2(X1A1) and HAlNH(X1A′) isomers using ab initio calculations at various levels of theory. These two isomers are potential candidates for astronomical observation. AlNH2 and HAlNH are thermodynamically stable, with Al-NH2 and HAl-NH bond dissociation energies predicted to be 4.39 and 3.60 eV, respectively. The two isomers are characterized by sizable dipole moments of 1.211 and 3.64 D, respectively. The anharmonic frequencies and spectroscopic constants reported for the two isomers should facilitate their experimental differentiation. In addition, we evaluated the evolution of the low-lying electronic states along the stretching coordinates, as well as the absorption cross sections. AlNH2 absorbs strongly around 287, 249, and 200 nm, whereas the HAlNH absorption is centered around 370 and 233 nm.

Published: May 2023

Samples from the Genesis Solar Wind Sample Return (NASA Discovery 5) are a unique opportunity to study the initial stages of space weathering, i.e., the physical and chemical effects of solar-wind irradiation. Arrays of collectors containing multiple materials were each exposed to a different solar-wind regime (fast, slow, bulk, or coronal mass ejection) at the L1 point for long durations (years). Materials exposed to the solar wind included metals, semiconductors, and insulators. Although the time of exposure was obviously short relative to samples having extraterrestrial origins, optical properties, surface chemical properties, and matrix structure have changed in many collectors due to exposure to solar wind. The thickness of amorphous zones, where present, appears to correspond with the depth of the peak of the solar-wind H distribution in each regime. Damage from high-energy particles was negligible because the collectors were 700 μm or less in thickness and shielded from the back by the spacecraft. Micrometeorite impacts and sputtering were also negligible because of the short exposure times. Our current results are preliminary: We hope future workers will extend this study both to support Genesis characterization efforts and to further understand space-weathering processes on a geologic timescale.

Published: May 2023

United and coordinated efforts of biodiversity data infrastructures are needed to bring together various data forms from many different scientific areas. Biodiversity data are considered of great importance and use when they form a network of knowledge that can be seamlessly integrated and presented to various audiences, promoting both research and education. The Biodiversity Community Integrated Knowledge Library (BiCIKL) project seeks to maximise the potential of integrated data sources by striving to connect fragmented data derived from biological, paleontological, and geological specimens and collections, as well as all derived information such as literature in the form of taxonomic treatments, research papers etc., taxonomic information and molecular sequences provided by these infrastructures, under the umbrella of common digital practices and policies in curation, data sharing and open data access over different scientific fields. One of the main goals of BiCIKL is to create bi-directional links between various data types, a process enabled by: a) the adoption of globally unique and persistent identifiers upon agreement among all stakeholders, that link to digital specimen objects, collections, taxonomic treatments, people, sequence data and taxa, and b) implementation of the best practices for the generation, management and curation of interlinked data by the host infrastructures. At the same time, infrastructures should be readily discoverable and accessible by end users, providing data that enable re-usability. In this manual we give an overview of the best practices and their associated recommendations for infrastructures on making the most out of their services and data, for establishing a network of knowledge with other infrastructures, for servicing researchers, data providers and other end users. These guidelines have been developed in collaboration with the infrastructures through Technical RI Forum meetings organised in the context of the BiCIKL project. Practices and recommendations were divided into six categories: 1) modalities of access, 2) building communities and trust, 3) technology and standards, 4) versioning of APIs and their data, 5) bi-directional linking between infrastructures and 6) API design patterns and naming conventions. A second division into three user groups (Infrastructures, Data providers, Users e.g. Researchers, Developers and Citizen scientists) is presented in Appendix I.

Aspects éthiques des soins crustatifs
Authors: Moureau Loïc , Liégeois Axel
Published: May 2023

Les soins crustatifs sont un modèle de soins développé pour les personnes souffrant de troubles psychiatriques sévères et persistants (TPSP). Nous présentons le modèle de soins crustatifs et l’illustrons par une étude de cas. Le modèle intègre des éléments de l’approche du rétablissement et de la philosophie palliative. En raison de leur vulnérabilité, la prise en charge des personnes atteintes de TPSP pose de nombreux défis éthiques : préconiser une approche holistique de la personne humaine, rechercher un équilibre entre autonomie, soins et protection, évaluer la capacité de décision, poursuivre une prise de décision partagée, rechercher une allocation équitable et durable des ressources, organiser une délibération morale et adopter des vertus éthiques.

La Société d’étude du féodalisme : documents, témoignages, perspectives
Authors: Abélès Solal
Published: May 2023

La Société d’étude du féodalisme, fondée en 1975, fut, sinon juridiquement dissoute, au moins définitivement mise en sommeil sans doute au plus tard au cours de l’année 1983. Guère citée dans la littérature scientifique contemporaine, peu évoquée ultérieurement par celles et ceux qui l’ont fréquentée et par conséquent quasiment oubliée aujourd’hui, elle a pourtant constitué l’un des lieux d’échange intellectuels les plus féconds de son époque en attirant plusieurs dizaines de participants réguliers, médiévistes et modernistes pour la plupart. En s’appuyant sur les documents produits en son sein et désormais constitués en archives ainsi que sur une série de témoignages rétrospectifs de cinq de ses principaux membres, le présent article se propose de poser les jalons de l’histoire de la société qui les a produits et d’ouvrir quelques pistes de réflexion à partir des pratiques de recherche dont elle témoigne.
Spectres marxistes du féodalisme : le passé d’une interprétation ? - 2ème partie
Authors: Dufal Blaise
Published: May 2023

La place du marxisme dans l’historiographie française du xxe siècle et particulièrement dans la médiévistique est assez tenue voire refoulée. Cette étude décrit les différentes formes de pénétration, de dialogue, d’usage ainsi que de refus et d’opposition vis à avis du marxisme de la part des médiévistes français. Ce panorama permet de saisir la singularité d’un moment marxiste particulier qui s’articule autour de la notion de féodalisme à partir de 1963 notamment autour du Centre d’Étude et de Recherche Marxiste. Le travail historique autour de cette notion marxiste est continué par la Société d’Étude du Féodalisme à partir de 1976, notamment par Guy Bois, Alain Guerreau, Jean-Claude Schmitt et Daniel Tollet et déploie de multiples aspects intellectuels, ouvrant à d’importants tournants scientifiques. Cette aventure marxiste marginale dans la médiévistique française se clôt de manière assez abrupte, pour sombrer ensuite dans l’oubli dès la seconde partie des années 1980.

O absurdo no existencialismo de Thomas Nagel
Authors: Ferreira Curcio Rafael
Published: May 2023

O presente artigo argumenta que a noção de absurdo desenvolvida por Thomas Nagel, em seu The Absurd, está longe de representar apenas a aventura de um filósofo analítico pelo território da filosofia continental. Isso porque a noção nageliana de absurdo se conecta com a questão central do seu pensamento, qual seja, o problema de como conciliar uma visão objetiva do mundo com uma visão subjetiva de uma pessoa dentro do mesmo mundo, tal como trabalhado em seu livro The View from Nowhere. Como o artigo esclarece, o absurdo concebido como uma discrepância inevitável entre a seriedade com que encaramos nossas vidas e a possibilidade de considerar tudo com o que nos importamos como arbitrário é a forma que o conflito entre a perspectiva objetiva e subjetiva assume no que diz respeito ao sentido da vida. Dessa maneira, o artigo enfatiza que a absurdidade, por ser uma consequência da capacidade humana de se desprender do ponto de vista particular, compartilha com outros problemas filosóficos analisados pelo filósofo, sobretudo, o ceticismo, a origem no conflito entre o ponto de vista objetivo e o ponto de vista subjetivo. Com a exposição da sua noção de absurdo, bem como da sua abordagem do problema geral entre a perspectiva objetiva e a subjetiva, o artigo procura mostrar como as suas reflexões de cunho existencialista estão integradas e são coerentes com o seu pensamento mais amplo.
Da crítica do ceticismo à construção de uma fenomenologia pura
Authors: Carvalho Guilherme Felipe
Published: May 2023

O presente artigo almeja demonstrar que em Einleitung in die Logik und Erkenntnistheorie, de 1906/07, por meio de uma crítica ao ceticismo, Husserl promove uma mudança que será significativa no desenvolvimento posterior de sua filosofia: a introdução da εποχή. Ao contrário do ceticismo grego, tal conceito em Husserl, ao suspender o juízo, busca um dado indubitável: o ego. Isso proporciona com que Husserl supere o ceticismo, tanto em sua face dogmática (negação de possibilidade de todo o conhecimento), quanto crítica (suspensão do juízo perante o alcance do conhecimento). Com isso, pode-se perceber que ao retomar um conceito cético da filosofia antiga, e opor-se ao relativismo, Husserl inaugura o seu primeiro esboço de uma filosofia pura, que adiante será concretizada, em sua última fase, como idealismo fenomenológico-transcendental.
O reconhecimento na teoria da eticidade formal de Honneth e a crítica de Michael Thompson:
Authors: De Lima Francisco Jozivan Guedes
Published: May 2023

Este artigo pretende revisitar o tema do reconhecimento em Honneth a partir de duas perspectivas: num primeiro momento aborda as esferas do reconhecimento mediante a proposta de eticidade formal que contém os aspectos normativo-universais e os aspectos contextuais inerentes aos processos de autorrealização. Num segundo momento apresenta a crítica de Thompson a Honneth segundo a qual a teoria do reconhecimento é falha por dois motivos fundamentais: (i) ela é incapaz de lidar com as dinâmicas e efeitos do poder social, isto é, ela prescinde de uma análise ontológica do “poder constitutivo” e da “dominação constitutiva”; (ii) ela se centra nas práticas intersubjetivas de reconhecimento e esquece de enfocar as estruturas e sistemas normativos de integração funcional.
A individuação dos seres incorpóreos no Liber de Causis
Authors: Sousa Meline Costa
Published: May 2023

Este artigo trata da individuação dos seres incorpóreos no Kalām fī maḥḍ al-ẖayr ou Liber de Causis (LdC). Tendo isso em vista, apresentarei a hierarquia dos seres, em especial, a distinção entre o intelecto e a alma. Após uma breve comparação entre os princípios no LdC (causa primeira, intelecto e alma) e nos Elementos de Teologia de Proclo (Uno, limite-ilimitado, henádes, intelecto e alma), discutirei a ausência das henádes divinas no LdC e as dificuldades encontradas pelo autor anônimo frente às mudanças realizadas na estrutura metafísica procliana. Riggs (2017) entende que o autor do LdC desenvolveu uma nova teoria para explicar a individuação, sem a mediação das henádes, baseada na distinção entre dois tipos de atividade: a criação realizada pela causa primeira e a doação de forma realizada pelo primeiro intelecto criado. Contudo, como discutirei, essas duas atividades não são capazes de justificar alguns aspectos do processo de individuação já que cada uma delas é um ato único realizado por um tipo de princípio externo, não por um princípio imanente ao próprio ser individuado. Uma interpretação alternativa para a teoria da individuação presente no LdC será proposta a partir de dois critérios: o princípio da semelhança (LdC X) e o princípio da proporcionalidade (LdC IX, XI).

Wire bonding is the preferred interconnection in the IC packaging. Understanding the electrical performance of bonding wire as transmission line is utmost important. To date, there is very limited studies on the transmission performance of fine pitch bare bonding wire especially the insulated wires. This paper investigated the transmission performance of single bare bonding wires and insulated bonding wires with different wire material, wire diameter, bonding height, insulation thickness at high frequency. The simulation analysis shows that when the frequency increases above 15Ghz, the effect of the geometric parameters has no significant different to the transmission performance. The thickness of the insulation between 0.1μm to 0.3μm reacted similar performance for return loss and insertion loss across all frequency

This paper investigates performance of ZnO/SnO2nanorods structure thin film deposited at two different ZnO seed layer (ZnO seed A and ZnO seed B) for humidity sensor application. ZnO seed A and ZnO seed B were deposited using two different method which were sputtering method and spin coating method respectively. ZnO/SnO2nanorods structure thin film that has been prepared on ZnO seed A and ZnO seed B using thermal chemical vapor deposition (CVD). The structural properties have been characterized using field emission scanning electron microscopy (FESEM) (JEOL JSM 6701F). Base on the FESEM image the size of ZnO seed A and ZnO seed B were ranging around 75 to 85 nm and 17 to 21 nm respectively. The results analyzed were for ZnO/SnO2composite nanorods structure size on ZnO seed A and ZnO seed B were averagely around 18 nm to 29 nm. The sensor properties were characterized by using current-voltage (I-V) measurement (Keithley 2400). ZnO/SnO2nanorods structure thin film deposited on ZnO Seed A performed highest sensitivity with 265 ratio compare to ZnO/SnO2nanorods structure thin film deposited on ZnO Seed B with 75 ratio of sensitivity.

SiC sputtered and e-beam evaporated layers have been deposited on 4H-SiC substrates. High temperature annealing with two plateaus at 1400°C and 1700°C is performed to recrystallize the layers. The crystallinity was investigated by Raman spectroscopy with laser lines of 785, 405 and 325nm. To determine the electrical conductivity of the layers, electrical measurements are made. Only the electron beam evaporated layers presents a recrystallization close to homoepitaxial quality but, contrary to sputtered layers, they don’t have an electrical conductivity.

Due to high growth temperatures during the physical vapor transport (PVT) it is still almost impossible to gain proper insight into the actual growth conditions. Therefore, computer tomography (CT) is used as an in-situ monitoring during the crystal growth process. With the help of this technique, it is possible to observe the nucleation centers during the initial stage of growth (CT after 0h) of a 4H-SiC single crystal. These growth islands are likely built before the actual growth conditions are reached. Raman investigations of the area around a growth island located directly on the interface between seed and grown crystal is used to support this assumption. In addition, optical analysis after KOH etching were made to reveal the defects around the growth island. The island exhibits a rough doping concentration in comparison to the surrounding grown crystal.

Published: May 2023

The present study aimed to investigate the effects of 8-week of coenzyme Q10 (CoQ10) supplementation alone or combined with concurrent training (CT) on functional capacity, serum brain derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in multiple sclerosis (MS) patients. Our hypothesis is that CT promotes improvements in the studied outcomes with higher results for the combination of CT and CoQ10. Randomized placebo-controlled trial. Twenty-eight patients with MS were randomly divided into 4 groups: CT+placebo, CT+CoQ10, CoQ10 and placebo. CT involved two resistance training sessions and one aerobic training session per week. CoQ10 was supplemented with 200 mg daily. Serum levels of BDNF, NGF and functional tests [timed up and go (TUG), 6-min walk (6MW), chest press, lateral pull down, leg extension, and lying leg curls one repetition maximum] were measured before and after the intervention period. CT+placebo and CT+CoQ10 significantly improved performance in TUG, 6MW, chest press, lateral pull down, leg extension, and lying leg curls, with superior results to both CoQ10 and placebo groups. Changes in TUG for CT+placebo were significantly higher than CT+CoQ10 (p<0.05). There were no significant differences in NGF and BDNF among the four groups (p >0.05). CT improves physical abilities in patient with MS, regardless CoQ10 supplementation. CT should be recommended for MS patients to increase functional capacity, but there seems to be no benefit in supplementing CoQ10.
“Our bodies are not strong anymore”: a focus group study on health risk perceptions of ambient air pollution near a petrochemical industry
Authors: Okoye Ogochukwu , Carnegie Elaine , Mora Luca
Published: May 2023

Background. Ambient air pollution has persisted in lessendowed communities, resulting in exposure to unhealthy pollutants. Epidemiological studies on air pollution have been mainly quantitative, with a dearth of information on community health risk perception, a key component of risk management.Objectives. The aim of this focus group study was to highlight the health risk perception of ambient air pollution among people residing near a petrochemical industry and to determine their perceptions of the existing control measures and ideas for more effective control.Methods. Participants were purposefully selected based on age, sex, long-term residence near a petroleum refinery, and occupation. Three 90-minute face-to-face focus groups and one individual interview were conducted. The moderator guided discussions using a pre-formed topic guide. Discussions were audio-recorded, transcribed manually, and coded using NVivo software. The data analysis was conducted using reflexive thematic analysis.Results. Six themes were generated: negative perception of the environment; the refinery is to blame; air pollution is seen or smelled; air pollution is associated with health and non-health risks; poor response to air pollution- everyone is to blame and the government is primarily responsible for healthy air quality. The participants were not aware of the extent of air pollution’s health risks. Suggestions for air pollution control included regulating gas flaring, environmental health education, and incentives for community members.Conclusion. Participants perceived that their ambient air was unhealthy. However, concerns about the health risks were shaped by contextual factors. The key barriers to effective mitigation were poor environmental health literacy and political factors.
Un obiettivo per il futuro

Questo editoriale doveva intitolarsi Verso una nuova normalità, ma il giorno in cui SCENARIO  è stato chiuso in tipografia, è uscito un focus sulla rivista L'Infermiere dal titolo similare Tornare alla normalit. Quale normalità (https://www.infermiere- online.org/2021/03/26/tornare-alla-normalita/).
La nostra prima reazione è stata quella di modificare completamente l'articolo di apertura, pensando che di fronte a titoli così simili si creasse confusione tra i lettori. Dopo esserci confrontati con alcuni infermieri, ed esperti del settore, abbiamo però deciso di mantenere il testo. La motivazione di pubblicare ugualmente il nostro editoriale solamente con l'aggiunta di questo preambolo iniziale e cambiando il titolo, nasce dalla considerazione che se due redazioni hanno la stessa idea nello stesso momento – senza essersi interfacciati nei giorni precedenti – significa che questo è un tema importante e dibattuto nella comunità professionale. Questo tema, come leggerete nel nostro articolo, è stato trattato anche da altre riviste, che hanno scelto la ricerca della normalità come obiettivo per il prossimo futuro.

Vaginal atrophy is a commonly encountered problem among young cancer survivors. Patients suffer from vaginal dryness, irritation, and dyspareunia secondary to oestrogen deficiency. Oestrogenbased hormone replacement therapy is effective, but unfortunately health concerns or contraindications in cancer survivors frequently limit its use. A 35-year-old female patient with dyspareunia that markedly affected her sexual relationship was referred to the gynaecology clinic. Treatment using topical oestrogen cream and sexual counselling were not successful. We treated her using two submucosal injections of PRP-non-cross-linked hyaluronic acid injections into the vestibule and lower third of the anterior vaginal wall mucosa, spaced a month apart. The patient reported marked reduction of dyspareunia and demonstrated an improvement of FSFI total score 1 month after the second injection. Both the patient and her husband showed an improvement of the index of sexual satisfaction score one month after the second injection compared to their pretreatment scores. Examination of the vaginal mucosa showed improvement of thickness and integrity of the mucosa and increased lubrication. PRP-non-cross-linked hyaluronic acid submucosal injections can be effective for cancer therapy-related vaginal atrophy, coitus-related pain, and sexual satisfaction.

Published: May 2023

Introduction:

Total body irradiation (TBI) plays a prominent role in the form of myeloablative conditioning before hematopoietic stem cell transplantation (HSCT). The primary indications for allogeneic HSCT are acute myeloid leukemia or acute lymphoid leukemia including patients in first remission with intermediate to high-risk features, induction failure, relapse, or second remission or beyond.

Context:

The utility of allogeneic HSCT is significantly restricted in resource-limited settings. The use of TBI as a preparative regimen before haploidentical transplant has been associated with a fast and improved engraftment. The present study was performed to build local capacity for delivering TBI.

Aims:

Establishment of an institutional protocol to deliver both low-dose and myeloablative TBI utilizing the available linear accelerator and facilities.

Subjects and Methods:

Implementation of TBI using a basic linear accelerator with single energy 6-MV photons without altering the room layout where space is a constraint. Measures were taken to achieve dose homogeneity within 10% variation and critical organs shielded with multileaf collimator using island-shielding technique.

Results:

The variation between dose prescribed and dose delivered was well within ± 10%. Phantom versus treatment planning system dose profiles were within ± 3% variation.

Conclusions:

The technique designed by our team enables us to attain homogeneous whole-body dose distribution with the standard protocol. This technique achieved better sparing of organs at risk with manageable side effects. It is economical and can be implemented readily. This could guide many centers to build local capacity, particularly working with resource constraints to improve their services further.
