Abstract
We present an improved methodology to obtain absolute position and velocity of meteor head echoes, which can yield orbital information, generally limited to the use of High-Power, Large-Aperture radars, using an advanced-designed specular meteor radar. The observations, which were performed during a period when an outburst of the β-Taurid meteor shower was expected, were performed with the Southern Argentine Agile MEteor Radar. Three different methodologies are utilized to confirm our results: an improved interferometric solver building on previous work, and two different target localization techniques using remote receiving stations. In addition, we performed simultaneous optical observations during the meteor shower period. Overall, 71 radar head echo events were detected and analyzed using interferometry, while 12 of those events have detected signals strong enough to be analyzed using localization methods at the remote sites. Due to poor weather, however, the optical cameras only observed two events simultaneously with the radar. Results from these events are in agreement with the radar results. We find that interferometry methods from both radar and optical data resulted in the most accurate estimation of meteor properties, while target localization techniques derived similar results, albeit with larger uncertainty. We also computed heliocentric meteoroid orbits, and while a fraction was hyperbolic, we believe these to be due to uncertainty. Two events are suspected to be β-Taurid shower members.
La pédagogie comme lieu d’interactions entre savoirs, recherches et pratiques
Authors: Vellas Etiennette 
Published: September 2021

Ce texte est une entrée dans l’espace intermédiaire que représente la pédagogie conçue comme élaboration d’une « théorie pratique ». Il rappelle que le pédagogue réalise, à partir de sa propre expérience éducative, une recherche spécifique de cohérence entre finalités, savoirs et pratiques de l’éducation. Après une contextualisation de la recherche pédagogique dans l'avènement des sciences de l'éducation, puis la définition de la pédagogie d’une personne et de celle d’un groupe, le texte se focalise sur le type de travail opéré par les pédagogues avec et sur leurs savoirs de référence. Trois processus sont mis en évidence dans ce travail pédagogique dont le but est d’agir et faire agir (au) mieux sur le terrain de l’éducation : une utilisation prévisible des savoirs de référence ; un travail plus aléatoire et créateur d’autres savoirs (les concepts de créolisation et de sérendipité sont appelés pour l’expliquer) ; un travail de sélection, laissant des savoirs issus de la recherche sur la touche des terrains éducatifs. Théoriciens de leurs propres actions éducatives, le pédagogue et le groupe de pédagogues apparaissent comme des créateurs de savoirs singuliers qu’ils transmettent, en entraînant dans cette diffusion des savoirs des sciences humaines.

Published: September 2021

Background:
Numerous studies have assessed the effect of photodynamic therapy (PDT) both as a primary mode of treatment and as an adjunct to scaling and root planing in the treatment of periodontitis. Some results were nondefinitive and, in part, inconsistent with respect to the clinical and biochemical effects. Hence, the aim of this study was to evaluate the effect of PDT as an adjunct to nonsurgical periodontal therapy (NSPT) on the gingival crevicular fluid (GCF) interleukin-6 (IL-6), IL-8, and IL-10 levels in the treatment of chronic periodontitis (CP).

Materials and Methods:
In 21 patients with CP, two contralateral sites (premolar and molar) were randomly divided into: control sites (treated with NSPT only) and test sites (treated with NSPT + PDT). Clinical parameters including bleeding on probing (BOP), probing pocket depth, clinical attachment level were evaluated at baseline, 1- and 3 months and biochemical parameters of GCF levels of IL-6, IL-8, and IL-10 were evaluated at baseline and 3-month post-therapy through enzyme-linked immunosorbant assay.

Results:
A greater improvement in BOP score at 1 month (41.10% ± 3.58%) and 3-months (38.00% ± 3.62%) posttherapy was found in the test site as compared to control site. Regarding cytokines, test sites exhibited significant reductions in IL-6 (4.29 ± 0.67 pg/ml) and IL-8 (308.16 ± 36.04 pg/ml) levels and increase in IL-10 (14.25 ± 0.83 pg/ml) level at 3 months (P < 0.0001).

Conclusion:
Additional application of PDT, adjunctive to NSPT, resulted in a significant reduction in BOP score as well as GCF pro-inflammatory cytokine levels along with an increase in anti-inflammatory cytokine levels, compared to NSPT alone.
Food Hygiene Practices of Rural Women and Microbial Risk for Children: Formative Research in Nepal
Authors: Gautam Om Prasad , Curtis Valerie 
Published: September 2021

ABSTRACT.
Formative research was conducted in a rural hill setting in Nepal during April–June 2012 to inform the design of an intervention to promote safe food hygiene practices. A variety of methods underpinned by Behavior Centered Design theory and Hazard Analysis Critical Control Points was used to pinpoint key risk behaviors and their environmental and psychological determinants in 68 households with a mother having a child aged 6–59 months. These included video recordings, observation of daily routine, teach-the-researcher sessions, in-depth interviews, observations of actual behaviors, focus group discussions, motive mapping, microbiological assessment, and identification of critical control points. Physical settings, especially the kitchen, form a challenging environment for mothers, including family members in rural hill settings of Nepal to practice adequate food hygiene behaviors. Prevalent food hygiene practices of mothers were inadequate, leading to frequent exposure of young children to highly contaminated food, water, and milk. We identified six critical control points; of these, five needed improving. Determinants of these behaviors included physical and social environment as well as psychological brief and individual motives. Five key food hygiene risk behaviors are suggested for prioritization. While designing a food hygiene intervention package, consideration should be given to the physical, biological, and social environment, and immediate motives behind each practice should be taken into consideration while framing key messages. Creative and engaging activities should be designed around the motives of nurture, disgust, affiliation, and social status/respect.
Case Report: HTLV-1–Induced Adult T-Cell Leukemia and Tropical Spastic Paresis

Published: September 2021

ABSTRACT.
Human T-lymphotropic virus type 1 (HTLV-1) is a retrovirus endemic in many areas around the world. HTLV-1 can induce the development of adult T-cell leukemia (ATL) or myelopathy/tropical spastic paraparesis (HAM/TSP). We report a patient who presented to our outpatient clinic with massive splenomegaly, weight loss, urinary retention, and lower extremity weakness for the previous 3 years. The patient was found to have positive HTLV-1 by ELISA and Western blot from peripheral blood. Evaluation of the spleen demonstrated T-cell large granular lymphocyte leukemia consistent with ATL. In addition to progressive lower extremity weakness, hyperreflexia and clonus, cerebral spinal fluid was positive for HTLV-1 by ELISA and had a reversed CD4-to-CD8 ratio consistent with HAM/TSP. These findings suggest HTLV-1 induced ATL and HAM/TSP presenting simultaneously in the same patient.

Published: September 2021

The advent of COVID-19 and its implication on university education has been the bone of contention in recent times. The COVID-19 emergency has led to a change in knowledge inputs, processes, and outputs. This trajectory has demotivated student approaches to their learning. In response to this revolution, this study provides motivational strategies through students' perspectives to respond to the underside of new normal among South African university students. Ubuntu underpins the study within the Transformative Paradigm lens and Participatory Research as a research design. Ten students of a particular module in a selected university in South Africa were chosen to participate in the study. They were selected using the snowballing sampling technique because the participants were under level 3 lockdown with little or no access to campus at the time of the study. Online interview via phone calls, email and WhatsApp, was conducted with the students, and the data were analysed using Thematic Analysis. The study revealed a lack of visualised physical engagement between students and their lecturers and unstable internet access and lack of the internet as the major challenges. The study, therefore, recommends solutions that there should be adequate provision of effective online audio-visual sessions with enough space for student-lecturer’s interactions and low-tech online sessions and content deliveries.
A journey through digital storytelling during COVID-19 Students preparedness to use technology for learning in the language classroom
Authors: Marais Elma 
Published: September 2021

The COVID-19 pandemic has forced lecturers at South African universities to reconceptualise their teaching and learning activities. Universities had to embark on remote teaching to salvage the 2020 academic year. This created the opportunity to draw on students’ creative and digital skills to promote digital storytelling as a way of enhancing their learning experience. This article describes the journey of a teacher educator and a group of students registered for a language didactics module in an initial teacher education programme. Film study was traditionally presented through lively conversations in a contact session where students could exchange their perceptions and opinions regarding various aspects of film. Because of the COVID-19 lockdown this approach had to be reviewed. The lecturer in question employed digital learning competencies to transform learning through the innovative use of digital tools and resources to rethink student engagement with film. Students were invited to create digital stories. The outcome of the process not only improved their understanding of teaching film but also promoted their digital competencies and empowered them to create resources they could use in their careers.

Authors: Barros Natalia Nakamura , Ruschel Regina Coeli , Silva Vanessa Gomes da 
Published: September 2021

A Avaliação do Ciclo de Vida (ACV) investiga sistematicamente os impactos ambientais e encontra aplicações inclusive na indústria da construção. Tao et al. (2014) desenvolveram uma arquitetura de Internet of Things (IoT) e extração de materiais em BIM para o nível de produção de produto. Este artigo apresenta resultados parciais de uma pesquisa de doutorado desenvolvida com o método Design Science Research (DSR), e mantém seu foco na fase de sugestão do método. Propõe-se uma adaptação do arcabouço conceitual de Tao et al. (2014) para aplicação à etapa de uso do edifício. O esquema IoT + BIM para ACV de edificações permaneceu com as mesmas camadas da estrutura proposta por Tao et al. (2014), mas altera o seu conteúdo devido ao propósito e escopo da ACV: (i) as atividades da camada de percepção estão relacionadas ao uso da edificação; (ii) a camada de dados inclui o modelo BIM e os dados de monitoramento de uso do espaço; (iii) A camada de serviço é reordenada e incorpora algoritmos de IA; e (iv) A camada de aplicação inclui profissionais de Arquitetura, Engenharia e Construção (AEC). Uma arquitetura de IoT baseada em BIM com inteligência para ACV no estágio de uso de edifícios é muito promissora e inovadora ao permitir a coleta de dados ambientais em tempo real, e a sua transformação - de forma inteligente e dinâmica - em indicadores. Esta estrutura será subsequentemente avaliada em ambientes institucionais de laboratório durante uma fase de uso.

Viewing dark triad as a positive personality trait, the researchers intend to explore the constructive use of impression management with regard to career success based on structural holes theory, paying particular attention to social capital and network benefits as sequential mediators between impression management and career success. A systematic literature review was conducted comprising published research studies on the chosen variables of interest. The researchers made use of several websites and links, like Google Scholar, PsychINFO, ResearchGate, and Web of Science. The systematic research was conducted to identify the desired variables and review was summarized from 2000 to 2020. Considering the past literature, it was proposed that impression management improves social capital that further leads to network benefits, thus, contributing to career success, whereas the dark triad strengthens the relationship between impression management and social capital. In last section, potential areas for future research in the context of impression management and dark triad are identified and a research agenda is put forward for the potential researchers. In future, researchers may benefit from the proposed conceptual model and can conduct a longitudinal quantitative research study considering the variables studied.

A Low Noise High Input Impedance Chopper-Stabilized Biopotential Amplifier with Ripple Reduction Technique
Authors: ADESARA Ankit , NAIK Amisha 
Published: September 2021

Biopotential signals are created as a result of the electrochemical activity of the many cells that comprise the nervous system, and they represent both normal and pathological organ function. These signals must be identified with extreme caution because they are surrounded by a great deal of noise when detected by sensors. This article explores a novel biopotential amplifier that incorporates the chopper stabilization technique to increase noise performance and minimize offset. However, by introducing the chopper modulator into the proposed design, the amplifier's overall input impedance was lowered, which was then increased to greater than 200 MΩ by adding the forward auxiliary path to the input branch. Additionally, the output ripple, produced due to switching activity and up-sampling, was reduced by inclusion of the R-C ripple removing block at the output of the operational transconductance amplifier (OTA). The designed architecture had a mid-band gain of 40dB with a power consumption of 9 µW and an offset of 10µV and a CMRR of 82 dB. It generated a noise of 42nV/√Hz. Also, the obtained results were compared with a conventional amplifier. The proposed design was verified by carrying out simulations using 180nm technology parameters. Cadence Virtuoso (Schematic editor), Spectre (Simulator), Symica and Magic (Layout) tools were used to complete the implementation and simulation of the proposed design.

Published: September 2021

Objetivo: O propósito desse trabalho foi realizar uma revisão bibliográfica enfatizando a relevância do Sistema Músculo Aponeurótico Superficial (SMAS) e dos ligamentos retentores da face em procedimentos estéticos. Revisão Bibliográfica: É de extrema importância, para minimizar o risco de ocorrências e complicações, que o profissional ao realizar procedimentos invasivos na face, conheça os planos e as estruturas presentes em cada região facial. O SMAS conecta os músculos faciais à derme e tem como objetivo transmitir, distribuir e amplificar a atividade de todos os músculos faciais. Os ligamentos verdadeiros são estruturas facilmente identificáveis que conectam a pele ao periósteo subjacente (membrana que cobre a superfície externa do osso). E os ligamentos de retenção falsos são condensações mais difusas de tecido fibroso que conectam a fáscia superficial e profunda à pele. Conclusão: O sucesso dos procedimentos estéticos da face tem relação direta com o conhecimento anatômico do profissional que o executa. Ao realizar procedimentos invasivos na face, é indispensável conhecer quais são os planos e as estruturas presentes em cada região facial. Este domínio minimizará os riscos de ocorrência de complicações e proporcionará maior segurança aos pacientes
