Contação de Histórias Para, Com, e Por Crianças na Escola da Infância
Authors: Vieira Débora Cristina Sales da Cruz
Published: October 2022

Neste artigo proponho a análise de performances narrativas de crianças pequenas produzidas na oficina lúdica Caixinha de guardar o tempo, realizada presencialmente em dezembro de 2021, em quatro instituições públicas de Educação Infantil localizadas em regiões periféricas do Distrito Federal. Estabeleço um diálogo entre saberes da Teoria Histórico-Cultural, dos Estudos Sociais da Infância e dos Estudos da Performance como aporte teórico, para discutir a potência da contação de histórias por crianças pequenas na escola da infância, em uma perspectiva de partilha dialógica. O percurso metodológico foi trilhado a partir da etnografia performativa com práticas artístico-pedagógicas de mediação de leitura e contação de histórias, abrindo espaço e tempo para a criação e materialização das performances narrativas das crianças pequenas, com a gravação em áudio, transcrição e produção da obra Crianças Narradoras. Destaco a compreensão das formas singulares como crianças pequenas criam e (re)criam, com autoria, as histórias narradas em contextos educativos, que se evidenciam como prática performativa de produção de culturas nas infâncias.
Comunidade Narrativa e Performance
Authors: Dalla-Bona Elisa Maria , Leal Selma Soczecki , Vaz Adriana
Published: October 2022

Neste artigo é apresentada uma coletividade que foi edificada pelas trocas de saberes durante os trajetos autoformativos de uma professora e uma comunidade de crianças narradoras, cujos laços e nós foram tecidos e entrelaçados nas várias edições do curso “Arte de contar histórias”, desenvolvido num Centro Municipal de Educação Cultural, no Município de Araucária, sul do Brasil. As principais reflexões teóricas versam sobre a instauração da performance lúdica, sobre o processo simbiótico entre quem narra uma história e quem lhe escuta, sobre o protagonismo da criança que no exercício de contar e ouvir histórias constrói saberes, alimenta sua imaginação e desenvolve sua criatividade, e sobre as vantagens da horizontalidade da relação entre crianças e adultos que passam a se constituir como autores mais conscientes das suas histórias de vida. Três experiências vividas durante o curso são relatadas, rememorando as histórias que versaram sobre temas difíceis como a morte, a condição da mulher na sociedade, o racismo, além do detalhamento das atividades implementadas que viabilizaram a formação de crianças contadoras de histórias.

Authors: Portela Cláudia Paranhos , Costa Livia Alessandra Fialho
Published: October 2022

O artigo é resultado de uma pesquisa, de natureza qualitativa, desenvolvida em Salvador, no ano de 2014, e cujo tema foi o percurso de cuidado e educação das pessoas com deficiência. Mais especificamente, perguntamos às famílias sobre a formação e atuação das redes de apoio parental e social no cuidado e educação da pessoa com deficiência intelectual. Analisamos, assim, as estratégias de cuidado elaboradas e experienciadas pelas famílias diante da necessidade de cuidar, educar e socializar filhos(as) com deficiência intelectual. A pesquisa foi baseada em entrevistas semiestruturadas com dezesseis famílias de pessoas com deficiência intelectual, adultas, moradoras de Salvador, Bahia. Os resultados obtidos na investigação revelaram uma realidade familiar em que as mães aparecem como as principais cuidadoras dos(as) filhos(as). Evidenciou-se também que o apoio fornecido pelas redes parental e social se revelam como fatores determinantes no processo de cuidado, educação e socialização do(a) filho(a) com deficiência intelectual, tendo em vista que, quanto maior é o apoio recebido, mais qualidade de vida se garante às pessoas com deficiência e às suas famílias. A pesquisa aponta a necessidade de novos estudos comparativos que estabeleçam a relação entre a influência das redes de solidariedade familiar e social no desenvolvimento da pessoa com deficiência intelectual
A Preparação do Conto e do Contador de Histórias
Authors: Santos Luciene Souza , Arapiraca Mary de Andrade , Carvalho Luciane Maria Ávila
Published: October 2022

O estudo aqui apresentado defende a ideia de que existe um portador de memórias em cada pessoa, que pode se revelar e se constituir em contador ou contadora de histórias, se dessa forma se descobrir. Tomando a Faculdade de Educação da [UNIVERSIDADE] como lócus da investigação, de inspiração etnográfica, e estudantes de Pedagogia como sujeitos da pesquisa, o estudo desenvolveu-se seguindo uma combinação de procedimentos e dispositivos de produção e coleta de dados e informações, o que compreendeu uma necessária pesquisa bibliográfica e a criação e implementação de uma oficina de contação de histórias para os sujeitos da pesquisa com realização de um grupo focal ao final das atividades. A discussão aqui posta é resultado do percurso de contação e escuta de muitas histórias que nasceu a partir da questão norteadora desse estudo: Que caminhos podem ser percorridos para a formação de sujeitos contadores de histórias? Tal questão foi respondida ou, por vezes, desdobrada em muitas outras. As reflexões que o estudo produziu a partir da interação com os jovens estudantes, autorizam as autoras a reafirmar: o contador de histórias aprende a contar a partir da rememoração das suas histórias fundantes – memória afetiva –, e é contando, muitas e muitas vezes, que ele se forma na arte de contar.

Considering the relevance of listening and telling stories for your human and reading formation, this article aims at showing the importance of planning the moments of storytelling, thinking carefully about the text and the techniques,elements and gestures that will be used in the narrative, so that the listener has a pleasurable experience with history and literature, also, possibilities of reading aloud relating text and image. For this, bibliographic studies were carried out from Busatto (2003), Sisto and Motoyama (2016), Silva (1986) and others, besides an experience report at Center for Studies in Reading and Children’s and Youth Literature CELLIJ of UNESP in Presidente Prudente and in the school library Wickliffe Progressive Community School, both spaces that seek ways to offer a humanizing experience with the literary text. Hence, with the studies and experiences described, it is possible to conclude that this millennial practice of storytelling must continue to be part of the experience of the new generations.
A Perspective on Using Virtual Reality to Incorporate the Affective Context of Everyday Falls Into Fall Prevention
Authors: Raffegeau Tiphanie E , Young William R , Fino Peter C , Williams A Mark
Published: October 2022

Virtual reality (VR) is a promising and cost-effective tool that has the potential to reduce the prevalence of falls and locomotor impairments in older adults. However, we believe that existing VR-based approaches to prevent falls do not mimic the full breadth of perceptual, cognitive, and motor demands that older adults encounter in daily life. Researchers have not yet fully leveraged VR to address affective factors related to fall risk, and how stressors such as anxiety influence older adult balance and real-world falls. In this perspective paper, we propose developing VR-based tools that replicate the affective demands of real-world falls (eg, crossing the street) to enhance fall prevention diagnostics and interventions by capturing the underlying processes that influence everyday mobility. An effort to replicate realistic scenarios that precipitate falls in VR environments will inform evidence-based diagnostics and individualize interventions in a way that could reduce falls in older adults in daily life.

Published: October 2022

Apendisitis merupakan salah satu penyakit tidak menular tertinggi di Indonesia pada rawat inap di rumah sakit. Sehingga pengobatan apendisitis perlu dikontrol, salah satunya dengan penggunaan Clinical Pathway (CP). Clinical pathway (CP) merupakan salah satu strategi untuk meminimalkan pemakaian sumberdaya. Untuk itu, diperlukan penelitian untuk menganalisis biaya penggunaan antibiotik pada pasien apendisitis yang sesuai clinical pathway pada pasien apendisitis di RS PKU Muhammadiyah Yogyakarta. Rancangan penelitian ini adalah cohort retrospektif dengan metode penelitian Cost Consequence Analysis (CCA) pada pasien rawat inap apendisitis dengan perspektif Rumah Sakit. Sampel pada penelitian ini dibagi menjadi dua kelompok yaitu sesuai clinical pathway dan tidak sesuai dengan clinical pathway. Data yang diambil adalah data biaya medis langsung pasien apendisitis, kesesuaian clinical pathway dan LOS pada periode Januari-Desember 2019. Data tersebut dianalisis kesesuaian penerapan clinical pathway-nya kemudian dilihat konsekuensinya berupa LOS dan biaya medis langsung. Hasil penelitian akan ditampilkan dalam bentuk tabel dan dianalisis secara deskriptif. Terdapat 73 pasien yang masuk dalam subyek penelitian. Jumlah pasien yang sesuai clinical pathway 55 pasien (75,3 %) dan yang tidak sesuai clinical pathway 18 pasien (24,7 %). Kesesuaian peresepan antibiotik sesuai CP sebesar 73,97%. 2. Biaya medis langsung total kelompok sesuai CP (ceftriaxone) adalah Rp 7.681.672 dengan rincian biaya obat sebesar 2.528.560 dan biaya jasa Rp 5.153.112. Sedangkan kelompok tidak sesuai CP adalah Rp 8.489.481 dengan rincian biaya obat sebesar Rp 3.016.539 biaya jasa Rp 5.603.342. LOS kelompok sesuai CP adalah 3,18 hari sedangkan kelompok tidak sesuai CP adalah 4,33 hari. Perbedaan biaya medis langsung dari kelompok sesuai CP dan tidak sesuai CP dengan INA-CBG’s adalah Rp 431.304 dan Rp 985.227. Berdasarkan uji chi square terdapat hubungan yang signifikan antara kesesuaian CP dengan lama rawat inap dengan RR 1,517 dan p value 0,03. Kesimpulan bahwa penerapan clinical pathway pasien apendisitis di Rumah Sakit dapat memperpendek LOS dan menghemat biaya medis langsung.
Biodiversity is not declining in fiction
Authors: Piper Andrew
Published: October 2022

This paper attempts to replicate the findings of the recent work, “The rise and fall of biodiversity in literature,” by Langer et al. (2021). Using a large corpus from Project Gutenberg (N = ~15,000) and a dictionary-matching method of over 240K biological taxa, Langer et al. find that the frequency and diversity of biological taxa have been declining steadily since the first half of the nineteenth century, echoing prior work in cultural analytics. This paper applies the original paper’s three primary measures to two additional data sets along with the original dataset and compares their dictionary-based method with an alternative supervised machine learning method. I find that the trajectory of biological tokens in fiction in the new data sets is directionally opposite to that shown by Langer et al. independent of the methods used (i.e. taxa rise rather than fall since the first half of the nineteenth century) but that their breakpoint estimation appears largely robust within +/- 15 years. Based on this analysis, I suggest that the discrepancy between our results is due to corpus construction rather than choice of method. I find that only conditioning on fiction in the original dataset generates results more similar to the two alternative datasets used here. In addition to emphasizing the importance of corpus construction for cultural analytics, these findings also raise larger questions about the difficulties of interpreting lexical items as indeces of social attitudes, pointing to a need for future work.

Экспонирование образца в герметичном контейнере с химическим маркером (спиртовой раствор пентабората цезия Cs[B5O7(OH)2] · 0.5H2O) в условиях переменного температурного режима (600 циклов нагрева / охлаждения) показало, что раствор цезия способен проникать вглубь образца через естественные коллекторы, сообщающиеся с поверхностью. Результаты маркирования скрытых микроколлекторов позволяют дифференцировать наложенные биогенные формы органического вещества, не связан ные с петрологической эволюцией эклогитов, от «первичных» эндогенных включений. В микровключениях органического вещества, в которых отсутствуют морфологические признаки бактериальной природы, обогащение цезием ниже предела обнаружения энергодисперсионного детектора в режиме пониженного вакуума сканирующего электронного микроскопа. Предположительно такие формы сингенетичны с эклогитами.
¿Qué impulsa a los docentes a participar en actividades científicas no formales?
Authors: Martín-García Jorge , Dies Álvarez María Eugenia
Published: October 2022

La enseñanza no formal proporciona cada vez más recursos con los que satisfacer las necesidades tanto de profesores como de alumnos. Sin embargo, la atención dirigida por la investigación a estos contextos ha sido reducida y, quizá por ello, su potencial no está del todo explotado. Por este motivo, es imprescindible conocer qué necesita el profesorado de estos espacios y qué espera de ellos.En el presente trabajo se ha indagado en las razones que llevan al profesorado de secundaria a participar en una actividad científica no formal como es el Concurso de Cristalización en la Escuela. El análisis de las respuestas ofrecidas por los docentes a un cuestionario de preguntas abiertas ha revelado la presencian de siete grandes categorías de respuesta que agrupan una gran variedad de motivos.Estos resultados amplían los recogidos en la bibliografía y además proporcionan un marco que permite interpretar las creencias del profesorado y comprender en mayor profundidad los motivos por los cuales deciden participar en actividades no formales. Por último, también remarcan las características del concurso mejor valoradas por los educadores permitiendo concluir que los docentes perciben el concurso como una experiencia muy enriquecedora y una herramienta formativa de lo más completa.

Authors: García González Mariel Anahí , Sánchez Mendonza Ernesto , Waksman Minsky Noemí Herminia , Saucedo Alma L
Published: October 2022

La Resonancia Magnética Nuclear (RMN) es una técnica espectroscópica utilizada en diversas áreas de las ciencias químicas, biológicas y de la salud. Es por ello, que la RMN forma parte esencial de la currícula de los programas educativos a nivel licenciatura en carreras afines a estas áreas. De acuerdo con nuestra experiencia docente, el primer abordaje de los estudiantes para aprender RMN se da a través de la lectura de bibliografía que comúnmente se encuentra  en idioma inglés, por lo que hemos detectado dificultades iniciales, ya que además de la problemática asociada al dominio de la lengua extrajera, los estudiantes también tienen que lidiar con el entendimiento de conceptos de química, física cuántica y matemáticas. En este sentido, el objetivo de este artículo de divulgación es proporcionar un material didáctico que facilite a estudiantes y profesores la introducción a  conceptos básicos de la teoría de RMN con ayuda de ejemplos y analogías. Este documento se recomienda como lectura previa a la impartición de la primera clase de fundamentos de RMN en los cursos de química orgánica, química analítica, química instrumental, y espectroscopía, entre otros.
Comprendiendo el enfoque 3D (conceptos centrales (DCI’s), conceptos transversales (CCC’s) y prácticas científicas (SEP’s)): Una propuesta de enseñanza para la química
Authors: Valera Flores Rocío Karina , Padilla Martínez Kira
Published: October 2022

Este trabajo busca ayudar, a docentes e investigadores, a comprender el enfoque tridimensional de la enseñanza de las ciencias. Esto mediante la exposición del significado e intención de cada dimensión del enfoque 3D y la propuesta de una actividad con dicho enfoque, para la enseñanza del tema de periodicidad. Se presenta un breve análisis de las diferencias que guarda el nuevo temario de Química III (propuesto en el año 2017 para la ENP) con la perspectiva 3D de la NRC. El cual, a pesar de la reducción de temas, aún conserva un enfoque tradicional en el que no se consideran las dimensiones del enfoque tridimensional (conceptos centrales (DCI’s), conceptos transversales (CCC’s) y prácticas científicas (SEP’s)). Después de presentar y hacer un análisis comparativo, se presenta una actividad que busca mostrar cómo es posible implementar dicho enfoque 3D en las aulas de química del bachillerato. Particularmente en esta actividad se presenta a los estudiantes la situación en la que Medeleyev da orden a las tarjetas de los elementos, en este caso los elementos son ficticios, pero guardan relación con los elementos de la tabla actual. En la actividad se desarrollan, para cada dimensión, los siguientes componentes: Estructura y propiedades de la materia (DCI’s); modelado (SEP’s); Estructura y función, Patrones, similitud y diversidad (CCC’s). La actividad es una propuesta para ser probada con estudiantes de bachillerato.

Área de actividad y uso de hábitat del cacomixtle (Bassariscus astutus) en “El Pedregal de San Ángel”
Authors: CASTELLANOS GABRIELA , LIST RURIK
Published: October 2022

La Reserva Ecológica “El Pedregal de San Ángel” es el último relicto del malpais originado de la erupción del volcán Xitle. Esta reserva de 237 ha está localizada dentro de la Ciudad de México, una de las ciudades más grandes del mundo, y alberga una población de cacomixtle (Bassariscus astutus). A pesar de su amplia distribución y su capacidad para tolerar la perturbación antrópica, se ha publicado poco acerca de la biología de esta especie. En esteestudio se evaluaron los patrones de actividad del cacomixtle en la Reserva “El Pedregal”. Para esto capturamos y colocamos collares de telemetría a 10 ejemplares; sin embargo, solo cuatro machos (3 adultos y 1 juvenil) produjeron localizaciones (37-71 localizaciones) para estimar el área de actividad. Se calculó el Polígono Mínimo Convexo (PMC) con 95% de datos (7.8 ± 1.9 ha adultos y 2.9 ha juvenil) y el Kernel fijo con el 95% de datos (9.2 ± 0.08 ha adultos y 3.1 ha juvenil), usando la extensión de Análisis de Movimientos de Animales de Arc View 3.1. Solamente hubo dos casos de sobreposición temporal de 28.08 % y 84.14 % entre un par de individuos, y 46.3% y 46.9% entre el otro par. En cuanto a uso de hábitat se obtuvo un uso mayor al esperado en los hábitats: perturbado (pesp = 0.256 < pmin = 0.284) y jardines y pastos (pesp = 0.155 < pmin = 0.125); y un uso menor al esperado en el pedregal (pesp = 0.189 > pmax = 0.13) y el ambiente urbano (pesp = 0.077 > pmax = 0.048); las construcciones de la UNAM tuvieron un uso igual al esperado (p = 0.22). El cacomixtle se encuentra en todo el campus universitario, en donde sobrevive en condiciones de alta fragmentación y urbanización.

Authors: Thomas Smeera , Joshy Greena , Subbiah Kavitha
Published: October 2022

Biosurfactants were found to be a suitable candidate for environment clean-up and as an alternative to conventional treatment systems. In the present study, a polyaromatic hydrocarbon degrading organism Bacillus halotolerans was screened for its ability to produce biosurfactant during hydrocarbon degradation. The bio-surfactant activity of the organism was screened by using various methods like oil spreading technique, emulsification assay, foam height analysis and parafilm-M test. The design expert software was used to optimize the suitable conditions for the production of biosurfactants. The optimum conditions were determined as pH 6, Chrysene-100 ppm, nitrogen source -1000 ppm and at 144 hrs using the design of experiments. The organism showed good oil degradation capacity and maximum growth was achieved in 6 days. Biosurfactant obtained from the biodegradation medium was confirmed to be lipopeptide using TLC, FTIR and GCMS.

Nitric oxide (NO) may protect against gas bubble formation and risk of decompression sickness. We have previously shown that the crucial co-factor tetrahydrobiopterin (BH4) is oxidized in a dose-dependent manner when exposed to hyperoxia similar to diving conditions but with minor effects on the NO production by nitric oxide synthase. By manipulating the intracellular redox state, we further investigated the relationship between BH4 levels and production of NO in human endothelial cells (HUVECs). HUVECs were cultured with and without ascorbic acid (AA) and the glutathione (GSH) synthesis inhibitor buthionine sulfoximine, prior to hyperoxic exposure. The levels of biopterins and GSH were determined in cell lysates while the production of NO was determined in intact cells. Omitting AA resulted in a 91% decrease in BH4 levels (0.49 Å} 0.08 to 0.04 Å} 0.01 pmol/106 cells, p<0.001) at 20 kPa oxygen (O2), and 88% decrease (0.24 Å} 0.03 to 0.03 Å} 0.01 pmol/106 cells, p=0.01) after exposure to 60 kPa O2. The NO generation was decreased by 23% (74.5 Å} 2.2 to 57.3 Å} 5.6 pmol/min/mg protein, p<0.001) at 20 kPa O2, but no significant change was observed at 60 kPa O2. GSH depletion had no effects on the NO generation. No correlation was found between NO generation and the corresponding intracellular BH4 concentration (p=0.675, r=-0.055) or the BH4 to BH2 ratio (p=0.983, r=0.003), determined across 18 in vitro experiments. Decreased BH4 in HUVECs, due to hyperoxia or lack of ascorbic acid, does not imply corresponding decreases in NO generation.

Pulmonary ventilation, expressed as respiratory minute volume (RMV) and heart rate (HR) were recorded during fast and slow descents to 35 meters (m) in open water while breathing compressed air, and during swimming horizontally at moderate velocity at an 11-m depth. Values of both types of descents were compared with reference values recorded at 11 m, the “plateau” phase, halfway through the 35-m dives. It is hypothesized that the “slowdescent” and “plateau-phase” values will be less than ‘fast-descent values. Depth, cylinder pressure, water temperature and HR were recorded with a dive computer yielding time-averaged means (mRMV and mHR) for the descent and for plateau. Of the 18 divers included, 16 performed the fast descents and 11 made the slow descents. The fast descents (23 m∙min-1 vertically), performed with 0-8 fin kicks, yielded mRMVDescent=28 ambient L (aL)∙min-1, which is 82% higher (P<0.001) than mRMVPlateau of 15 aL∙min-1. Further, mHRDescent was121 beats∙min-1 23% higher (P<0.001), than mHRPlateau of 100 bpm. Slow descents (2.4 m∙min-1 vertically) yielded 17 aL∙min-1 with mHR=101 beats∙min-1, values only slightly higher than at Plateau. The 11-m dive (swimming horizontally) yielded 24 m∙min-1 with 32 fin kicks∙min-1, mRMV=35 aL∙min-1 and mHR=115 beats∙min-1. Fast descents cause a higher RMV and HR that cannot be explained by physiology alone. Presumably mental stress is a main contributor. For dives deeper than 20 m, a descent velocity of 10 m∙min-1 is recommended to reduce cardiac stress, in particular for older divers.

Introduction/Background: The incidence of complications and number of critically ill patients in hyperbaric medicine is relatively low [1]. This poses a challenge to those tasked with educating trainees as well as maintaining the skills of staff. Hyperbaric medicine fellows may not be exposed to critical patient scenarios or complications of hyperbaric medicine during a one-year fellowship. Additional staff may be unfamiliar with these situations as well. The purpose of hyperbaric simulation curriculum is to train health care providers for rare situations. To our knowledge, this hyperbaric simulation curriculum is the first published use of simulation education in the specialty of undersea and hyperbaric medicine. Materials and methods: Two simulation cases have been developed that involve a patient with oxygen toxicity during hyperbaric treatment as well as an ICU patient with mucous plugging. Results: Medical training simulations are an effective method of teaching content and training multiple roles in Undersea and Hyperbaric Medicine. Summary/Conclusions: A hyperbaric simulation curriculum is an achievable educational initiative that is able to train multiple team members simultaneously in situations that they may not encounter on a regular basis. We believe that this could be easily exported to other institutions for further education.

Prenatal stress exposure (PSE) has been observed to exert a programming
effect on the developing infant brain, possibly with long-lasting
consequences on temperament, cognitive functions and the risk for
developing psychiatric disorders. Several prior studies have revealed
that PSE associates with alterations in neonate functional connectivity
in the prefrontal regions and amygdala. In this study, we explored
whether maternal psychological symptoms measured during the 24th
gestational week had associations with neonate resting-state network
metrics. 21 neonates (9 female) underwent resting-state fMRI scanning
(mean gestation-corrected age at scan 26.95 days) to assess fractional
amplitude of low-frequency fluctuation (fALFF) and regional homogeneity
(ReHo). The ReHO/fALFF maps were used in multiple regression analysis to
investigate whether maternal self-reported anxiety and/or depressive
symptoms associate with neonate functional brain features. Maternal
psychological distress (composite score of depressive and anxiety
symptoms) was positively associated with fALFF in the neonate medial
prefrontal cortex (mPFC). Anxiety and depressive symptoms, assessed
separately, exhibited similar but weaker associations. Post hoc
seed-based connectivity analyses further showed that distal connectivity
of mPFC covaried with PSE. No associations were found between neonate
ReHo and PSE. These results offer preliminary evidence that PSE may
affect functional features of the developing brain during gestation.
Neurophysiological oscillatory mechanisms underlying the effect of mirror visual feedback-induced illusion of hand movements on nociception and cortical activation
Authors: Rizzo Marco , Petrini Laura , Percio Claudio Del , Arendt-Nielsen Lars , Babiloni Claudio
Published: October 2022

Mirror Visual Feedback (MVF)-induced illusion of hand movements produces
beneficial effects in patients with chronic pain. However,
neurophysiological mechanisms underlying these effects are poorly known.
Here we hypothesized that such an MVF-induced movement illusion may
exert its effects by changing the activity in midline cortical areas of
the pain neural matrix. Electrical stimuli with individually fixed
intensity were applied to the left hand in healthy adults to produce
painful and non-painful sensations during unilateral right-hand
movements with such an MVF illusion and right and bilateral hand
movements without MVF. During these events, electroencephalographic
(EEG) activity was recorded from 64 scalp electrodes. Event-related
desynchronization (ERD) of EEG alpha rhythms (8-12 Hz) indexed the
neurophysiological oscillatory mechanisms inducing cortical activation.
As compared to the painful sensations, the non-painful sensations were
specifically characterized by (1) lower alpha ERD estimated in the
cortical midline, angular gyrus, and lateral parietal regions during the
experimental condition with MVF and (2) higher alpha ERD estimated in
the lateral prefrontal and parietal regions during the control
conditions without MVF. These core results suggest that the MVF-induced
movement illusion may affect nociception and neurophysiological
oscillatory mechanisms reducing the activation in cortical limbic and
default mode regions.
A Novel System Matrix Building Algorithm for Stability Analysis of Interconnected DC Microgrids
Authors: K. Jithin , N Mayadevi , R Harikumar , P Mini V.
Published: October 2022

DC Microgrids (DCMGs) are achieving critical significance these days
because of their colossal benefits as compared with the existing AC
systems. However, with the high penetration of sources interfaced to the
grid using various Power Electronic Converters (PECs), stability is
often a crucial issue, especially during the interconnected operation of
Microgrids (MGs). Hence, before the interconnection of DCMGs, the
stability of the resultant system needs to be guaranteed. In this work,
a novel step-by-step procedure, that does not require a complete
rebuilding of the system matrix when a new DCMG is added through a
distribution line to the cluster, is proposed. Furthermore, stability
analysis of the individual DCMGs and the cluster is performed from a
control system perspective using the eigenvalue method. From the
analysis, it is seen that, even though the individual MG units operate
as a stable system, the resulting clusters may not be stable. The
stability issues of the cluster are resolved by tuning the controller
parameters with Particle Swarm Optimization (PSO). The results reveal
the importance of stability analysis and the selection of optimum
controller gains for the reliable operation of DCMG clusters.

Published: October 2022

The negative impact of the synthetic antimicrobials and the overuse of
antibiotics have caused global concern, which necessitates the
development of a new form of antimicrobials that are derived from
natural compounds. In this study, the synthetic route of producing water
soluble iso-fatty acid arginate hydrochloride derivatives is
investigated by introducing branched (iso-) chain and other linear- (n-)
chain fatty acids to the amino acid “arginine” molecules. The two-step
synthesis is straightforward and provides an efficient 91%, 88%, and
76% product yield for ethyl n-lauroyl arginate hydrochloride, ethyl
n-oleoyl arginate hydrochloride, and ethyl iso-oleoyl arginate
hydrochloride, respectively. ATR-FT-IR, NMR, and LC-MS-Q-TOF techniques
are used to thoroughly characterize the products. The antimicrobial
characteristic of the synthesized ethyl n-lauroyl arginate (LAE) shows a
similar activity against both Gram+ and Gram- bacteria as the commercial
LAE product. However, its analogs are found to have antimicrobial
property primarily against Gram-positive bacteria.
Morphometric analysis and genetic diversity in Hedera L. (Araliaceae) species populations using sequence related amplified polymorphism
Authors: Hai-Yan Yu , Li Zhang , Jian-Cheng Luo
Published: October 2022

In temperate latitudes across Europe, North Africa, and Asia, the genus
Hedera L. colonizes forest understory and riparian vegetation. The goal of
this research was to investigate SRAP (Sequence-related enhanced
polymorphism) markers in overall 70 successions of Hedera types, that is
comprised of three species Hedera helix L.; Hedera colchica (K.Koch) K.Koch
and Hedera pastuchovii Woronow. Overall, 76 (Number of total loci) (NTL) DNA
bands were created via polymerase chain reaction amplifications (PCR)
amplification of three Hedera types. These bands were obtained by combining
five distinct selective primers. The overall amount of amplified varied from
10 to 18. The projected impartial gene diversity (UHe) ranged from 0.013
(Hedera colchica) to 0.34 (Hedera colchica) (Hedera helix). The genetic
similarity of three varieties is considered to be between 0.63 to 0.90. The
clustering findings revealed two main groups. Hedera helix and Hedera
colchica have the least affinity in the SRAP (Sequence-related amplified
polymorphism) indicators study. Our findings revealed excellent molecular
recognition of every genotypes tested, indicating that the Hedera accessions
exhibit a lot of genetic variation. This discovery might be useful in
breeding control techniques for genetic preservation and cultivar growth.

Published: October 2022

To find the best inoculation method for evaluation of the resistance in
potato genotypes against bacterial blackleg caused by Pectobacterium
atrosepticum under in vitro conditions, five inoculation methods were
compared. In vitro grown explants of five potato genotypes were inoculated
with different inoculation methods, then placed on MS solid medium and
incubated at 23?C with 70% relative humidity under the light regime of 16
hours a day. After the appearance of symptoms, the efficiency of inoculation
methods was then recorded based on the severity of disease symptoms in
potato genotypes: Farmosa, Agria, Picaso, Marfona and a wild potato genotype
?Solanum phureja'. Plantlets inoculated by piercing the crown with sterile
toothpick inoculated in bacterial suspension of 108 cfu/ml showed the most
severe symptoms. Based on all experiments, cultivar Marfona showed higher
resistance among all cultivars and, cultivar Agria was the most susceptible.
Finally, after witnessing the reactions of different varieties to
inoculation methods and comparing them with previous evaluations of
resistance in greenhouse conditions, the crown treatment employing sterile
toothpick after infection in 108 cfu/ml bacterial suspension was selected
and introduced as the best evaluation method of in vitro potato explants
against blackleg.
