Published: October 2022

This study provides a comprehensive description of the deposition of meteor-ablated metals in the upper atmosphere of Mars, accounting for the temporal, vertical, latitudinal, and seasonal distribution. For this purpose, the Leeds Chemical Ablation Model is combined with a meteoroid input function to characterize the size and velocity distributions of three distinctive meteoroid populations around Mars—the Jupiter-family comets (JFCs), main-belt asteroids, and Halley-type comets (HTCs). These modeling results show a significant midnight-to-noon enhancement of the total mass influx because of the orbital dynamics of Mars, with meteoroid impacts preferentially distributed around the equator for particles with diameters below 2000 μm. The maximum total mass input occurs between the northern winter and the first crossing of the ecliptic plane with 2.30 tons sol−1, with the JFCs being the main contributor to the overall influx with up to 56% around Mars’ equator. Similarly, total ablated atoms mainly arise from the HTCs with a maximum injection rate of 0.71 tons sol−1 spanning from perihelion to the northern winter. In contrast, the minimum mass and ablated inputs occur between the maximum vertical distance above the ecliptic plane and aphelion with 1.50 and 0.42 tons sol−1, respectively. Meteoric ablation occurs approximately in the range altitude between 100 and 60 km with a strong midnight-to-noon enhancement at equatorial latitudes. The eccentricity and the inclination of Mars’ orbit produces a significant shift of the ablation peak altitude at high latitudes as Mars moves toward, or away, from the northern/southern solstices.
Multi-Disciplinary Access in Conceptual Design for Advertising of The Public Space
Authors: Chaloska Ivana
Published: October 2022

This master's thesis is a qualitative empirical research for multidisciplinary conceptualization of an urban public space, with emphasis on development processes for affirmation of ecological and social sustainability, and structuring of socio-spatial relations. The research includes an inter-contextual analysis of a comprehensive theoretical context and a specific case study that highlights urban community gardens as potential initiatives for spatial and social reshaping. The findings of the research support a conceptual design of public space that popularly does not result in a tangible product, but can also be activism for rethinking what exists or a continuous process of socio-spatial relations. The research complements the theoretical framework of the design methodology with conceptual analysis of the design as a process of continuous integration of several disciplines.
Bosnian Chardaklia House: Mara Popovic's House in Gracanica
Authors: Hadrovic Ahmet
Published: October 2022

Mara Popovic's house in Gracanica, although built in an urban setting, seems to belong to the classic solution of a three-tract bosnian house chardaklia. The house was built in the city district named Varos on a gently sloping terrain with southern exposure.
The house was erected (1840) by a father-in-law, Mara Popovic, who lived in this house until her death, after which the property changed several owners.
Today, this house is owned by the Municipality of Gracanica, and is used by the well-known association “Gracanicko keranje”, which nurtures the tradition of making indigenous handicrafts from the Gracanica area – “keranje”. Due to its exceptional architectural, historical and environmental values, this house is included in the list of national monuments of Bosnia and Herzegovina.
According to its spatial concept, construction and materialization, long-term use and its present purpose, the house is an example of traditional and bioclimatic architecture of Bosnia and Herzegovina.

Authors: Santana Eurivalda Ribeiro dos Santos , Lautert Síntria Labres , Filho José Aires De Castro , Nunes Célia Barros , Santos Ernani Martins dos
Published: October 2022

Este artigo tem por objetivo principal problematizar o desenvolvimento profissional de professores que ensinam matemática ao participarem de um processo formativo on-line, realizado no âmbito de uma comunidade profissional de aprendizagem, que visa abordar a equidade no ensino de conceitos estatísticos. A pesquisa é aportada em referenciais teóricos de Desenvolvimento Profissional, princípios e dimensões de equidade para a aprendizagem em matemática e características de uma comunidade profissional de aprendizagem. A pesquisa foi desenvolvida pela Rede Educação Matemática Nordeste (REM-NE), que é composta por oito universidades situadas em quatro estados do Nordeste brasileiro e uma no Sudeste.  O processo formativo aconteceu em 2020, com a participação de 51 professores de oito escolas do ensino fundamental, parceiras da REM-NE, durante a pandemia da COVID-19, e concluído por 38 professores. A espiral RePARe (reflexão-planejamento-ação-reflexão) deu sustentabilidade para as ações formativas, distribuídas em Grupo Grande, com todos os professores e pesquisadores, e em Grupos Pequenos, formados por um quantitativo de, no máximo, seis professores e um pesquisador (formador). Todo o processo ocorreu de maneira on-line, fazendo uso do Telegram, do WhatsApp e das aplicações do pacote G-suite: Google Classroom, Drive, Meet e Google Forms. Para alcançar o objetivo deste artigo, analisamos dados coletados nos encontros do Grupo Grande: gravações; diários de bordo de nove encontros formativos; instrumento de perfil; diagnóstico do conhecimento específico; questionário sobre a perspectiva a respeito da equidade, além de diários de bordo dos encontros dos Grupos pequenos. Os protocolos de pesquisa foram analisados, e os resultados indicam que as formações de professores precisam valorizar e potencializar o desenvolvimento profissional de professores, no sentido de abordar: conhecimentos específicos (nesta pesquisa, conceitos da estatística); conhecimentos sobre práticas de ensino que possibilitem o trabalho com o estudante. Além disso, envolver a comunidade escolar abordando temáticas, dificuldades e fenômenos inerentes à própria noosfera em que está inserido o professor; ter a participação da universidade nos processos formativos, constituindo comunidades profissionais de aprendizagem; ter a educação crítica como cenário formativo e valorizar o trabalho com equidade; proporcionar o uso de ferramentas tecnológicas; dar valor aos processos de reflexão e planejamentos colaborativos. Os resultados indicam que esses são pontos inerentes e necessários a serem considerados em um processo formativo que vise ao desenvolvimento profissional.

Published: October 2022

O isolamento social decorrente da pandemia de COVID-19 suspendeu as aulas desde março de 2020 na maior parte das cidades do país e passou a exigir dos educadores uma postura crítica e criativa, capaz de gerar alternativas diante do imprevisível que se presentificou em nossas vidas. Nesse contexto, o trabalho desse artigo, que se integra à pesquisa mais ampla, propõe compreender processos da formação docente como parte da multidimensionalidade do funcionamento de um sistema municipal de Educação Infantil, por meio da compreensão de como professoras subjetivam uma vivência formativa. Com base na Teoria da Subjetividade e na correspondente Epistemologia Qualitativa de González Rey, abordam-se sentidos subjetivos produzidos pelas professoras como grupo social e a forma como essa produção se configurou, nesse contexto de exceção, como resposta possível à formação profissional e à imposição da tecnologia em suas práticas cotidianas. Para além de aspectos que singularizam a experiência desse grupo social, a construção-interpretativa traz, também, a produção particular da subjetividade individual de uma dessas docentes, considerando que a experiência formativa se constituiu para a professora como contexto favorecedor de aprendizagem sobre a função e os processos da educação escolar na primeira infância em relação à sua trajetória docente.

Dénoncer les abus des GAFA pour encourager la réflexivité ou pour réhabiliter la théorie des effets puissants des médias ?
Authors: Jehel Sophie
Published: October 2022

Le docudrame The Social Dilemma, diffusé sur Netflix, est un objet intéressant au regard de la question de la réflexivité numérique et de son lien avec une écriture hybride documentaire et fictionnelle. Le producteur en accompagne la promotion par des déclarations d’intentions éducatives et des mises en garde quant aux dangers des réseaux socio-numériques pour les démocraties. L’article analyse dans un premier temps le discours pamphlétaire et messianique du docudrame et l’usage qu’il fait lui-même de techniques de captation de l’attention. Il donne dans un second temps les résultats d’une enquête exploratoire auprès de lycéens de 16 à 18 ans. Le docudrame suscite peu de réflexivité numérique, il offre un prêt-à-penser facile, celui de la thèse des effets puissants des médias sociaux. Des espaces de discussion organisés sont nécessaires pour permettre aux jeunes de renforcer des postures autonomes et des questionnements favorables au développement de formes d’esprit critique.
On a coupled system of fractional $ (p, q) $-differential equation with Lipschitzian matrix in generalized metric space
Authors: Boutiara Abdellatif , Alzabut Jehad , Ghaderi Mehran , Rezapour Shahram
Published: October 2022

This work is concerned with the study of the existing solution for the fractional $ (p, q) $-difference equation under first order $ (p, q) $-difference boundary conditions in generalized metric space. To achieve the solution, we combine some contraction techniques in fixed point theory with the numerical techniques of the Lipschitz matrix and vector norms. To do this, we first associate a matrix to a desired boundary value problem. Then we present sufficient conditions for the convergence of this matrix to zero. Also, we design some algorithms to use the computer for calculate the eigenvalues of such matrices and different values of $ (p, q) $-Gamma function. Finally, by presenting two numerical examples, we examine the performance and correctness of the proposed method. Some tables and figures are provided to better understand the issues.
Applied machine learning for blood pressure estimation using a small, real-world electrocardiogram and photoplethysmogram dataset
Authors: Wong Mark Kei Fong , Hei Hao , Lim Si Zhou , Ng Eddie Yin-Kwee
Published: October 2022

Applying machine learning techniques to electrocardiography and photoplethysmography signals and their multivariate-derived waveforms is an ongoing effort to estimate non-occlusive blood pressure. Unfortunately, real ambulatory electrocardiography and photoplethysmography waveforms are inevitably affected by motion and noise artifacts, so established machine learning architectures perform poorly when trained on data of the Multiparameter Intelligent Monitoring in Intensive Care II type, a publicly available ICU database. Our study addresses this problem by applying four well-established machine learning methods, i.e., random forest regression, support vector regression, Adaboost regression and artificial neural networks, to a small, self-sampled electrocardiography-photoplethysmography dataset (n = 54) to improve the robustness of machine learning to real-world BP estimates. We evaluated the performance using a selection of optimal feature morphologies of waveforms by using pulse arrival time, morphological and frequency photoplethysmography parameters and heart rate variability as characterization data. On the basis of the root mean square error and mean absolute error, our study showed that support vector regression gave the best performance for blood pressure estimation from noisy data, achieving an mean absolute error of 6.97 mmHg, which meets the level C criteria set by the British Hypertension Society. We demonstrate that ambulatory electrocardiography- photoplethysmography signals acquired by mobile discrete devices can be used to estimate blood pressure.
Ethical Publishing: How Do We Get There?
Authors: Racimo Fernando , Galtier Nicolas , De Herde Véronique , Bonn Noémie Aubert , Phillips Ben , Guillemaud Thomas , Bourget Denis
Published: October 2022

The academic journal publishing model is deeply unethical: today, a few major, for-profit conglomerates control more than 50% of all articles in the natural sciences and social sciences, driving subscription and open-access publishing fees above levels that can be sustainably maintained by publicly funded universities, libraries, and research institutions worldwide. About a third of the costs paid for publishing papers is profit for these dominant publishers' shareholders, and about half of them covers costs to keep the system running, including lobbying, marketing fees, and paywalls. The paywalls in turn restrict access of scientific outputs, preventing them from being freely shared with the public and other researchers. Thus, money that the public is told goes into science is actually being funneled away from it, or used to limit access to it. Alternatives to this model exist and have increased in popularity in recent years, including diamond open-access journals and community-driven recommendation models. These are free of charge for authors and minimize costs for institutions and agencies, while making peer-reviewed scientific results publicly accessible. However, for-profit publishing agents have made change difficult, by co-opting open-access schemes and creating journal-driven incentives that prevent an effective collective transition away from profiteering. Here, we give a brief overview of the current state of the academic publishing system, including its most important systemic problems. We then describe alternative systems. We explain the reasons why the move toward them can be perceived as costly to individual researchers, and we demystify common roadblocks to change. Finally, in view of the above, we provide a set of guidelines and recommendations that academics at all levels can implement, in order to enable a more rapid and effective transition toward ethical publishing.
Process-Sensitive Naming: Trait Descriptors and the Shifting Semantics of Plant (Data) Science
Authors: Leonelli Sabina
Published: October 2022

This paper examines classification practices in the domain of plant data semantics, and particularly methods used to label plant traits to foster the collection, management, linkage and analysis of data about crops across locations—which crucially inform research and interventions on plants and agriculture. The efforts required to share data place in sharp relief the forms of diversity characterizing the systems used to capture the biological and environmental characteristics of plant variants: particularly the biological, cultural, scientific and semantic diversity affecting the identification and description of plant traits, the methods used to generate and process data, and the goals and skills of those with relevant expertise—including farmers and breeders. Through a study of the Crop Ontology (which explicitly recognizes and negotiates diversity) and its application to cassava breeding, I argue for a process-sensitive approach to the naming of plant traits that focuses on documenting environmental processes instead of biological products. I claim that this approach can foster reliable linkage and robust re-use of plant data, while at the same time facilitating dialogue between data scientists, plant researchers, breeders, and other relevant experts in ways that crucially inform agricultural interventions. I conclude that the study of data semantics and related descriptors constitutes a productive and underexplored way to think about the epistemic import of naming traits within plant science. The effort to articulate semantic differences among plant varieties and methods of data processing can generate newly inclusive ways to develop and communicate biological knowledge. In turn, such practices have the potential to defy existing understandings of systematisation and hierarchies of expertise in biology, thus bolstering the extent to which plant science can support biodiversity and sustainable agriculture.
L’État, l’argent et les cultes de 1958 à 1987
Authors: Moisset Jean-Pierre
Published: October 2022

Entre 1958 et 1987, le droit français s’est enrichi de mesures favorables aux intérêts des cultes : exonérations fiscales, garantie publique des emprunts, etc. Quelle histoire se cache derrière ces nouvelles dispositions légales ? Comment la Ve République a-t-elle construit un cadre qui sert les intérêts des cultes tout en respectant l’interdiction de leur financement public posée en 1905 ?

Le présent ouvrage montre que des responsables catholiques ont su trouver une oreille attentive auprès de décideurs politiques appartenant aux différentes familles de la droite. Dans les années 1960, leurs demandes visaient à abaisser le coût de construction des églises. Au cœur des années 1970, l’enjeu était l’intégration à moindres frais des prêtres, religieux et religieuses à la Sécurité sociale. Une décennie plus tard, il s’agissait de relancer le denier du culte en autorisant sa déductibilité fiscale.

Chemin faisant, le rapprochement de l’État et des religions organisé par la loi Debré (1959) sur le terrain scolaire a été complété sur le plan cultuel par une série de dispositifs qui restent d’actualité.

Authors: Martins Teresa Alves , Nunes João Arriscado , Dias Isabel , Menezes Isabel
Published: October 2022

A pandemia trouxe ruturas significativas em várias dimensões da vida, implicando adaptações intensas e visibilizando velhas e novas desigualdades e exclusões, como as associadas ao idadismo. Através de uma etnografia online analisamos as estratégias desenvolvidas por uma associação portuguesa constituída por pessoas reformadas em resposta às limitações à sua ação trazidas pela COVID-19. A maioria da comunicação organizacional passou a ser online e a associação desenvolveu novas iniciativas para a prossecução da sua missão. As publicações na página pública de Facebook refletiram tensões com as quais as pessoas mais velhas foram confrontadas, recorrentemente associadas a fenómenos de idadismo, denunciados e problematizados pela associação. Neste estudo constatamos que também em organizações de pessoas adultas mais velhas houve transição para ferramentas online durante a pandemia, com a utilização do Facebook como plataforma de comunicação e como recurso para a ação política.
Critical Literacy
Authors: Castillo Paula Renata
Published: October 2022

This chapter reviews the definition of critical literacy education as well as the benefits of applying this approach. It analyzes the statement that literacy is not a technical skill, but in fact, it is always embedded in socially constructed epistemological notions and power relations in society. The author includes a reflection on how texts are not neutral and the need to encourage children to interrogate what they read and to use language as a way to question inequalities and oppression. The chapter analyzes why this approach has been rarely implemented in early childhood classroom. The author proposes the need for educators to reflect about how their beliefs regarding literacy influence their teaching practices. It argues that children's literature can be a resource to dialogue about identity, culture, diversity, and power relations in society. Finally, it analyzes the importance to build a curriculum based on children´s interests and needs as well as to create spaces for critical literacy in early childhood classrooms.
Crafting Stories of Voice and Influence
Authors: Salmon Angela K.
Published: October 2022

The interplay between language, cognition, and the effects of emotions promote language and literacy development. Children have a natural inclination to build on other children's stories, which is the origin of the collective stories of voice and influence discussion. Stories are empowering venues that give children a voice and simultaneously open windows for them to step inside someone else's shoes, make connections, take perspective, and construct meaning. Stories make us human; children become aware of the world around them by listening and sharing stories. This action research project reports the process of children listening to stories and tailoring the telling of a story to a specific audience. Children were cognitively and emotionally engaged in interpreting stories and transmitting their messages through dialogic thinking and boundary objects. The children made their stories visible using a pedagogy of multiliteracies to tell stories in a natural, playful, safe, and engaging way.
Development of Language and Identity Through Author's Chair and Draw and Tell in the Context of Storytelling in Early Childhood Classrooms
Authors: Xu Jiamin , Najera Kenia
Published: October 2022

Storytelling is powerful. Young children use stories to share experiences, cultural beliefs, and thoughts in their early years. This chapter aims to examine the impact of traditional and digital storytelling on language development and identity among young immigrant children. In a study conducted with young children, they were encouraged to tell and share their personal stories with their classmates in a comfortable and engaging environment created by the author's chair and the draw and tell technique. The authors observed and analyzed the children's work in the after-school program over time and saw that they developed social skills and became confident communicating in their newly acquired language by sharing their own stories. The power of language and culture immersion intertwines with stories that encourage young children to freely communicate and share in a safe space, which fosters children's identity and language development.

Authors: Trigos-Carrillo Lina , Calle-Díaz Luzkarime , Guerra-Lyons Jesús
Published: October 2022

The effects of the pandemic, natural disasters, wars, and economic distress at the turn of the second decade of the 20th century are a call to strengthen peace education around the world. In this chapter, the authors argue that intentional social practices of critical literacies offer opportunities for peacebuilding, understood as a dynamic process which includes the development of harmony in different life dimensions. After providing an overview of peace research and peace education in the Colombian context, the authors provide a conceptualization of critical literacy and its relation to peacebuilding. Finally, the chapter offers a set of practical strategies to promote peacebuilding through critical literacies based on research experiences across the Americas. The strategies include the use of children's literature to understand social reality and to develop empathy, critical literacies to develop critical intercultural awareness, and connecting with families and communities through literacy practices to make peace.
Economic Downturn and Implications
Authors: Mandal Pratap Chandra
Published: October 2022

Companies and businesses operate in an uncertain business environment. The environment is more turbulent during a recession or an economic downturn. Investments done by firms are directly affected by such uncertainties. Recession and economic downturn make it uncertain and risky for firms. Firms worry that the returns will not be commensurate with the investments done. Nevertheless, there are firms which develop strategies, undertake initiatives, and invest during such tough times. Various strategies and initiatives adopted by companies and businesses to survive and even to excel during such tough times are discussed. The advantages and disadvantages of adopting those strategies and initiatives are discussed. The study focuses on firms which implemented strategies to overcome recession and established themselves in the minds of customers. Firms and practitioners will benefit from the study and will be able to identify the most effective strategies and initiatives to be adopted to achieve excellence during an economic downturn.
The Role of Machine Learning in Creating and Capturing Value
Authors: Costa-Climent Ricardo
Published: October 2022

The use of machine learning technologies by the world's most profitable companies to personalise their offerings is commonplace. However, not all companies using machine learning technologies succeed in creating and capturing value. Academic research has studied value creation through the use of information technologies, but this field of research tends to consider information technology as a homogeneous phenomenon, not considering the unique characteristics of machine learning technologies. This literature review aims to study the extent to which value creation and value capture through machine learning technologies are being investigated in the field of information systems. Evidence is found of a paucity of publications focusing on value creation through the use of ML in the enterprise, and none on value capture. This study's contribution is to provide a better understanding of the use of machine learning technologies in information systems as a social and business practice.

Authors: Rathore Nitin , Rajavat Anand
Published: October 2022

The growing number of connected IoT devices and their continuous data collection will generate huge amounts of data in the near future. Edge computing has emerged as a new paradigm in recent years for reducing network congestion and offering real-time IoT applications. Processing the large amount of data generated by such IoT devices requires the development of a scalable edge computing environment. Accordingly, applications deployed in an edge computing environment need to be scalable enough to handle the enormous amount of data generated by IoT devices. The performance of MSA and monolithic architecture is analyzed and compared to develop a scalable edge computing environment. An auto-scaling approach is described to handle multiple concurrent requests at runtime. Minikube is used to perform auto-scaling operation of containerized microservices on resource constraint edge node. Considering performance of both the architecture and according to the results and discussions, MSA is a better choice for building scalable edge computing environment.

Objetivo: conhecer a percepção de enfermeiros em relação à atenção às pessoas com hipertensão e/ou diabetes na Atenção Primária a Saúde (APS). Método: trata-se de pesquisa qualitativa, descritiva e exploratória, desenvolvida com 14 enfermeiros vinculados a municípios de uma regional de saúde do Paraná/BR. A coleta dos dados ocorreu no mês de setembro de 2021 por meio da técnica participativa intitulada Painel Integrado, a partir de quatro questões norteadoras, mediadas por três docentes e quatro discentes. Os dados foram transcritos e submetidos a análise interpretativa. Resultados: foram identificados seis tópicos de interesse: Estratégias de atendimento; Organização das consultas de enfermagem; Desafios para a realização da consulta de enfermagem; Potencialidades para a realização da consulta de enfermagem; Desafios da Rede de Atenção as Condições Crônicas; e Potencialidades da Rede de Atenção as Condições Crônicas. Considerações finais:  a percepção dos enfermeiros sobre o atendimento às pessoas hipertensas e diabéticas se dá por ações programadas e espontâneas que visam ao controle glicêmico e pressórico. As consultas de enfermagem usualmente ocorrem previamente à consulta médica e sem sistematização. Desvelou-se também que os enfermeiros reconhecem sua importância nesse contexto, porém a rotina e a alta demanda se constituem como desafios a serem vencidos a sim de melhorar a prática exercida.

Patterns of aerial photo weather in Canada
Authors: Fleming J
Published: October 2022

Weather suitable for high altitude aerial survey photography is defined in terms of cloud cover, horizontal visibility, and solar altitude. With these criteria established, relevant weather observation data stored in the electronic archive of the Meteorological
Service of Canada were isolated and used to compute a single figure value for each observation station, each month, for each of two minimum solar altitudes. Isopleths were then plotted on suitable base maps to depict the mean frequency of occurrence of observations meeting the criteria over a
10-year period. During the study of the accumulated data, it became apparent that four major areas which exhibit distinctive zonal photo weather patterns are to be found in Canada. Possible reasons for the existence of these zonal distributions are discussed in terms of their regional and local,
geographical and meteorological characteristics. The information presented in this report is statistical and standard deviations from mean values in the data were not possible. This and other limitations on the application of the data to specific cases is discussed.

Antioxidant and genoprotective effects of osthole against cadmium-induced DNA damage
Authors: Vahidifar Ehsan , Sajjadi Seyed Ebrahim , Etebari Mahmoud
Published: October 2022

Background and purpose:

Osthole, a plant-derived coumarin, has shown numerous pharmacological effects. However, its genoprotective effects against cadmium-induced DNA damage have not been determined yet. Therefore, this project aimed to assess the effectiveness of osthole against genotoxicity caused by cadmium.

Experimental approach:

For this purpose, human umbilical vein endothelial cells (HUVECs) were incubated with various concentrations of osthole (40, 60, 80, and 120 µM) 24 h before cadmium chloride (CdCl2) treatment (40 µM), and then DNA damage was evaluated by comet assay. Furthermore, DPPH and free thiol group assays were applied to evaluate reactive oxygen species scavenger and antioxidant capacities of osthole.

Findings / Results:

In the present study, all concentrations of osthole significantly decreased CdCl2-induced DNA damage. Furthermore, the antioxidant properties of the osthole were confirmed by DPPH and free thiol assays.

Conclusion and implications:

Overall, the findings of this project revealed that osthole could ameliorate cadmium-induced genotoxicity probably by its antioxidant activity.

Published: October 2022

Background and purpose:

Plantago major has been applied as a herbal remedy for centuries. However, studies on anti-inflammatory activities and their chemical ingredients are limited. The objective of this study was to investigate the anti-inflammatory properties of P. major in three animal models and its phytochemical contents.

Experimental approach:

Dichloromethane extract (DCM) of P. major was fractionated with n-hexane to yield the soluble (SHF) and insoluble (IHF) fractions. The anti-inflammatory activities of DCM, SHF, and IHF were evaluated using rat’s paw edema induced by carrageenan, thioglycolate-induced leukocyte emigration in the mice, and rheumatoid arthritis (RA) induced by complete Freund’s adjuvants in rats. The chemical constituents were analyzed using a high-resolution mass spectrometer (HRMS).

Findings / Results:

The DCM, SHF, and IHF inhibited paw edema in the rats and reduced the leukocyte migration in the mice. At dose 560 mg/kg, the percentage of inhibitory was 47.33%, 55.51%, and 46.61% for the DCM, IHF, and SHF, respectively. In the RA animal model, IHF at 280 and 560 mg/kg reduced osteoclast formation and COX-2 expression compared to diclofenac. Some compounds namely oleic acid, linoleic acid, palmitic acid, and oleamide identified in the DCM, IHF, and SHF may be responsible for these activities.

Published: October 2022

Juvenile idiopathic arthritis (JIA), the most common chronic rheumatological disorder in children, can result in significant disability and poorer health-related quality of life. Rehabilitation aimed at pain management, optimizing musculoskeletal function, improving endurance and achieving independence in activities of daily living, and participation in age-appropriate activities, is a vital component in the comprehensive management of children with this condition. Rehabilitation strategies depend on the phase of the disease and focus on pain alleviation in the active phase and improving mobility and function in the inactive phase. Rehabilitation in JIA is multidisciplinary and includes exercise therapy, physical modalities, orthotic and assistive devices, and gait training. Exercise therapy has demonstrated improvement in muscle strength, bone mineral density, exercise capacity, and quality of life, without negative consequences of pain or exacerbation of arthritis. Common exercise interventions for children with JIA include mobilization, strengthening, aerobic exercises, Pilates-based exercises, aquatic therapy, and recreation. Physical modalities such as thermotherapy, cryotherapy, electrotherapy, ultrasound, and low-power laser therapy are commonly employed. Orthotic devices play an important role in joint protection, prevention and reduction of joint deformities, and assistance with function and gait. Assistive devices are prescribed to improve functional ability and independence in activities of daily living in children with disabilities. There have been recent advances in the field of rehabilitation with the advent of robotics, virtual reality, and telerehabilitation.

Background: Recent studies reported the relationship between genetic variations and TAS2R38, which is a bitter taste receptor expressed in the cilia of human sinonasal epithelial cells, among the predisposing factors playing role in immune response to upper respiratory tract bacterial infection. The present study aims to examine the relationship of TAS2R38 genotype with the active microorganism and the effect of genotype on the surgical outcomes among chronic rhinosinusitis patients. Methodology: 34 patients undergoing endoscopic sinus surgery (ESS) for chronic rhinosinusitis with or without polyps (23 CRSwNP, 11 CRSsNP) and 30 patients undergoing septoplasty surgery for isolated nasal septum deviation were included. All the patients were genotyped for TAS2R38. Scoring was made using endoscopic Modified Lund-Kennedy and radiological Lund-Mackay systems preoperatively. Sino-Nasal Outcome Test with 22 items (SNOT-22) was implemented preoperatively and postoperatively. Nasal swab culture samples were taken intraoperatively from CRS patients and the active microorganism were isolated. Results: In the TAS2R38 genotyping of the study group, PAV/PAV was found in 32.4% of patients, PAV/AVI in 47.1%, and AVI/AVI in 20.6%. In the control group, PAV/PAV was found in 26.7%, PAV/AVI in 36.7%, and AVI/AVI in 36.7%. In the study group, there was no statistically significant difference between the CRS and CRS subgroups in terms of TAS2R38 genotype distributions. The changes in patients' preoperative and postoperative SNOT-22 scores were similar between the genotypes. Proliferation was detected in culture in the whole AVI-AVI group, 81.8% of PAV-PAV group, and 56.3% of PAV-AVI group but the difference was not found to be statistically significant. The proliferation level of Staphylococcus epidermidis by TAS2R38 genotype was found to be statistically significantly higher among patients, who had AVI-AVI genotype, in CRSwNP. Conclusions: We did not find a statistically significant relationship between the TAS2R38 genotype and CRS subtype, sinonasal bacterial infection risk increase and surgical success rate in CRS patients. Long-term and large-scale studies are needed, which are to be carried out by individual genotyping and sequencing to provide more information on the effects of these genetic variants.

Heavy metal contamination of the ecosystem remains one of the severe global threats. Even in trace quantities, heavy metals and metalloids such as chromium, lead, mercury, cadmium, nickel, and cobalt are toxic and carcinogenic, posing a serious threat to human life. Certain microbes and plants have evolved detoxifying pathways to fight the harmful effects of these inorganic metals, paving the door for bioremediation. Because of its environmentally benign nature, economic viability, and low labor and effort requirements, bioremediation outperforms other approaches in eliminating heavy metals. This review highlights the potential of microbes on remediation of heavy metals in the context of environmental protection and also focuses on the critical tolerance mechanisms used by these microbes in combating heavy metal contaminations. Furthermore, the bioremediation potential of bacteria, fungus, algae, plants, biosurfactants, biofilms and genetically altered microorganisms for the removal of these heavy metals was reviewed in this study. Applying these techniques as a sustainable environmental technology in the near future has shown synergistic benefits with a many-fold increase in the removal of heavy metals.

Controlling the vector population in the environment may contribute to reducing the clinical dengue cases. This study aimed to evaluate the use of ovitraps to monitor the entomological indices of A. aegypti and verify if the traps contribute to reducing dengue cases in Ibirité, MG. The traps were made using a medium plant pot, a wooden pallet, a clip and Saccharomyces cerevisiae. It was installed one trap every 15 days and, over three years (2019, 2020, 2021), resulted in 32 traps, distributed in the houses of 12 districts of Ibirité. After seven days of permanence, they were collected for eggs counting. A total of 60.433 eggs of A. aegypti were included in the Municipality, with the highest number observed in the Durval de Barros neighborhood. In 2019, 13.455 eggs were captured from January and May and between September and December. The IPO in the neighborhoods ranged from 9% to 54%, with the IDO ranging from 2 to 45 eggs. In 2020, 17.301 eggs were recorded, mainly from January to March and between October and December. The IPO in the neighborhoods ranged from 36% to 90% with the IDO ranging from 19 to 107 eggs. In the year 2021, there were 29,677 eggs between January and November that year, with the highest capture between January and March. The IPO was or higher for the three years of validity (70 to 10%), allowing us to infer that the traps help in the fight against dengue.

O estudo da imaginação ocorreu no contexto de uma atividade investigativa e a partir da aprendizagem como uma produção subjetiva. Esboçamos o percurso do estudo cujo referencial teórico é a Teoria da Subjetividade de González Rey, sustentada na Epistemologia Qualitativa e na Metodologia Construtivo-Interpretativa, do mesmo autor. Refletimos sobre as condições geradas na pesquisa para estudar a imaginação de um estudante – Pietro, com destaque para uma atividade sobre a respiração dos fungos. Apresentamos os principais resultados, explicitando a construção de indicadores novos, a ampliação da hipótese do estudo e o avanço na compreensão da configuração subjetiva da ação de aprender de Pietro. Assim, a atividade proposta nos ajudam a investigar a imaginação do estudante no curso de uma ação, que demandou a criação de uma representação de um planejamento para o experimento sobre a respiração dos fungos. Primeiro, porque o espaço relacional dialógico se constituiu em uma estratégia pedagógica, para alcançar o pensamento do participante e envolve-lo afetivamente. Segundo, porque a atividade demandou a produção de ideias, resultando na construção de um modelo de conhecimento pelo estudante, e suas reflexões sobre se os resultados obtidos teriam capacidade para responder ao problema proposto. As interpretações geradas a partir dos indicadores formulados, com base nas expressões do participante, permitem compreender a hipótese de que participam de sua configuração subjetiva da ação de aprender, núcleos de sentidos subjetivos, associados: à participação dos pais nos seus estudos; a sua postura desinibida, participativa, curiosa, responsável, e que não teme se expressar; e ao seu desejo de ascender na vida. Estratégias pedagógicas como concebidas na perspectiva da Teoria da Subjetividade, com espaços de diálogo, confiança e afetividade, podem se constituir importantes para a emergência de sentidos subjetivos favoráveis ao processo de aprender.
