Paleomagnetism of the Sainte-Cécile and Saint-Sebastien granitic intrusive
Authors: Seguin M. K.
Published: May 2021

Se presentan resultados paleomagnéticos de muestras de un intrusivo ácido de edad Devónica Media-Tardía, localizado en el sur de Quebec, Canadá. Las direcciones de magnetismo remanente determinadas son diferentes de las direcciones correspondientes a la plataforma estable de Norte América o a la zona de Avalón. Las direcciones medias obtenidas de 31 sitios colectados en tres tipos diferentes de granitos son: 045°, -14°, α95= 11° y 102°, 48°. Las posiciones polares correspondientes son: 164°E, 31°N (016°W, 31°S) y 170°E, 13°S (010°W, 13°N). Al parecer el cuerpo intrusivo no fue afectado por la Orogenia 'Acadian' del Devónico Medio ni por rotación local. Evidencias geológicas indican que intrusiones graniticas como las de St. Cecile y St. Sébastien representan la última fase de la Orogenia `Acadian'. Considerando la cantidad de datos disponibles, se estima aun prematuro establecer una subdivisión entre los polos correspondientes a la zona de Avalón (micro-continente) y los del Cinturón móvil central, durante el Devónico Media al Tardío. Se sugiere la ocurrencia de un movimiento polar aparente durante este periodo. Dicho movimiento se infiere de los resultados de direcciones de desmagnetización para las diferentes fases de intrusión, que representan un periodo relativamente corto; dichas direcciones muestran importantes discrepancias. Se considera prematuro dar una conclusión sobre la posible presencia de una zona de esfuerzo tangencial paralela a alguna de las zonas tectono-estratigráficas.
Atmospheric diffusion characteristics at a coastal site in the tropics

Published: May 2021

Utilizando los datos de temperatura y viento (a 10 y 60 m) de una torre meteorológica ubicada en el sitio costero de Laguna Verde, Ver., se intenta determinar algunas características de la estructura térmica y las propiedades turbulentas de la capa planetaria. En una situación de 'Norte' el transporte de contaminantes al centro de población más grande (Veracruz) se realizaría en un tiempo corto. Aun cuando la extensión horizontal de la pluma es pequeña en el caso de un Norte, la mezcla en la vertical debida al calentamiento desde abajo fomentaría la dilución. Tanto la brisa como el terral muestran valores pequeños de la dispersión horizontal. La determinación de categorías de estabilidad por el método de Pasquill resulta en una mayor frecuencia de condiciones de aire inestable en el sitio que la que resulta de aplicar los métodos de delta-t y sigma-teta durante el día. Por la noche se observa una mayor coincidencia entre los métodos de delta-t y sigma-teta.
Gradientes de velocidad en la Corteza y Manto Superior de las islas Baleares (Mar Mediterráneo)
Authors: Cordoba D. , Banda E.
Published: May 2021

En este trabajo se presenta un estudio de amplitudes para las ondas refractadas en el basamento y manto superior a partir de datos de perfiles sísmicos realizados en las islas Baleares durante el año 1976. Se consigue una acotación de los gradientes de velocidad en la corteza y manto superior, entre 0.0 y 10-2·s-l en el basamento cortical y entre 0.0 y 50xl0-4 s-l en el manto superior. El gradiente encontrado en el manto es un orden .de magnitud inferior al existente en la Cuenca Provenzal al Norte de las islas Baleares. Se sugiere que estas diferencias se deben al carácter continental del promontorio Balear.
Aplicación de técnicas de correlación de anomalías geofísicas al Noreste de la Península de Yucatán
Authors: Gonzáles-Moran T. , Suro Pérez V.
Published: May 2021

La correlación de anomalías magnéticas y gravimétricas permite reducir la ambigüedad existente en la interpretación geológica Estas técnicas se basan en la hipótesis de que variaciones en la litología y propiedades físicas de la corteza cristalina son reflejo de la mineralogía que controla la densidad de las rocas que la forman y por otro lado del contenido de magnetita, causa primaria de las anomalías magnéticas. En este artículo, se procesa información geofísica marina de la línea 5 y 6 del Proyecto IDOE (International Decade of Ocean Exploration), recolectada en el noreste de la Península de Yucatán en el Mar Caribe, estableciendo una comparación cuantitativa entre la primera derivada vertical de la anomalía gravimétrica y la intensidad magnética total reducida al polo. Las anomalías, tanto gravimétricas, como magnéticas, muestran un patrón paralelo a la costa. Su análisis indica la presencia de una cordillera con orientación NE-SW, resultado de un fallamiento regional que originó una fosa tectónica, cuyas crestas parciales serian la Isla Cozumel y el Banco Arrowsmith.

Authors: Farreras S. F. , Villalba F. A.
Published: May 2021

Se aplica un modelo numérico unidimensional para dispersión, basado en las ecuaciones de continuidad, conservación de sa1, y conservación de un contaminante, al Estero de Punta Banda, B. C. Mediante este modelo se obtiene la variación espacio-temporal de la concentración de un contaminante conservativo, introducido en forma local e instantánea en un segmento del Estero. El modelo se calibra comparando su solución para un caso particular, con las mediciones de decaimiento de la concentración de un trazador fluorescente, inyectado en un lugar del Estero. Se simula con el modelo la introducción de contaminante en distintos segmentos del Estero, bajo las mismas condiciones hidrodinámicas anteriores, obteniendo de sus predicciones la subdivisión del estero en zonas, según su rapidez de evacuación.

Published: May 2021

Kangean is an island that has various traditions, one of which is the engagement tradition. Today, the engagement tradition has undergone a drastic shift, due to the presence of technological media, such as television, cell phones, the internet, and the like. Television, which is basically a medium of entertainment for the wider community, however, for the kangean community, television is one of the causes of social and cultural changes. This study aims to uncover and describe the causes of these changes. This study uses data analysis. Qualitative methods are methods that aim to obtain descriptive data. The data in this study are conversations related to the causes of socio-cultural shifts, the data is transcribed into written texts. The data was collected by interviewing, selecting, describing and verification techniques. Data were analyzed by using descriptive qualitative method which is based on Siswantoro's theory. The results of this study indicate that non-educational shows on television such as soap opera films, promiscuty, blue film, tiktok, life style, speaking style and dress patterns are greatly affect the kangean community especially among teenagers. The negative affects for Kangean teenagers are on social life, lifestyle, speaking style, promiscuty, drug addicts, violating customs, traditions and culture. Therefore, policies are needed to limit the scope of globalization to which ones should be implemented and which should be rejected. This requires the role of the government of the kangean community to act through policies that are more directed at socio-cultural considerations.

Mitologi Representation Dewa Indra in Pandage War at Usaba Waste Ceremony in the Tenganan Traditional Village Pegringsingan Manggis, Karangasem, Bali (Social Theological Perspective)
Authors: Subamia I Nyoman , Suastika I Made , Linggih I Nyoman
Published: May 2021

Pandan war is one of the important ceremonies and obligatory ceremonies called Usaba Sambah in the people of Tenganan Pegringsingan to God in manifestation as Dewa Indra. To raise three problems, namely (1) the form of pandan war , (2)axiology of  theology social of pandan war, and (3) the implications of pandan war.This study carried out qualitatively, so that data analysis was carried out in a qualitative and interpretative descriptive manner. By using research methods, such as participatory observation, interviews, literature studies, and documentation studies. The results showed that: (1) The process of pandan war was one of the most important and obligatory parts of the religious ceremony in the Usaba Sambah ceremony in Tenganan Pegringsingan Village (2) The axiology of social theology in pandan war is (a) pandan war as a form of worship; (b) pandan war as a life learning process; (c) pandan war as a pattern of social interaction; (d) pandan war as a defense of religious traditions; and (e) the pandan war as a show of the ancient warrior knight. (3) the implication of pandan war in the usaba sambah ceremony is (a) increasing the śraddhā and the devotion of the peregraningan community; (b) fostering a sense of togetherness between low income communities; (c) strengthen in maintaining the local historical genius; (d) the interaction of communication between communities is established; (e) applying the value of ancestral heritage as a living foundation; and (f) pandan war as the development of cultural tourism destinations. The research findings are as follows. From the perspective of religious theory, the symbol system used in pandan war is maintained especially the concept of pingit (secret). The concept of pingit in pandan war is when the pesangkepan is not allowed to pray / spells known by anyone other than pemangku. In this case, it should only be known by the designated party only. From the perspective of the value theory, it was found that the pandanus war is a sacred dance of offerings, which should not be danced by others which is only carried out on pandanus war on the first day at Bale Petemu Kaja and not in any place. Based on symbolic interaction theory, a shift in meaning of pandan war arises from social interaction between local communities, shifting to global community interaction through warfare on the second day as a venue for tourism promotion in modern tourism contractions. There are other people (not the Tenganan people) who also participated in many pandan wars on the stage performance.

Published: May 2021

Strawberry fruit has five levels of maturity in terms of the color of the strawberry fruit. One of the important factors that affect the fruit's resistance from mechanical damage is the level of fruit maturity. At different levels of ripeness, strawberries have different nutritional content. The strawberries used are obtained from strawberry farmers in Pancasari Village, Tabanan Regency. The level of fruit maturity analyzed was divided into five stages, namely 0, 25%, 50%, 75%, and 100% of the red fruit. Based on the ANOVA variety results, the parameters of color, texture, pH, total acid content, total acid content, vitamin C content, and anthocyanin levels of strawberries at different levels of maturity showed very significant differences (P <0.01). Strawberry fruit at the optimal level of maturity obtained the value of L *, namely 18.45, a *, namely 67.04, b *, namely 20.86, texture of 7.46 N, pH of 3.36, total acid of 2.09 (meq NaOH / g), total dissolved solids was 6.40 oBrix, vitamin C levels were 66.24 mg / 100, and anthocyanin levels were 329.07 (mg PGN / 100 g).

Published: May 2021

This study aims to determine the screening of endophytic bacteria isolatd from Mimosa pudica in Bali Island. This research was conducted from September 2020 to January 2021 at the Plant Disease Laboratory, Faculty of Agriculture, Udayana University, Denpasar. Isolation of endophytic bacteria was carried out by taking a sample of the root of the shy daughter plant which was then washed and dried on a tissue.. Hypersensitivity test followed Klement and Goodman (1967) by growing bacteria in a petri dish containing 100% TSA and NA.Tests were carried out by growing endophytic bacteria in 100% NA and TSA media.  Isolation of the roots of the Mimusa pudica plant resulted in 43 isolates. The resulting isolates then passed the hypersensitive test so that 27 isolates were selected. A total of 27 isolates were then tested for hemolysis on blood agar. The final results obtained were 12 endophytic bacterial isolates which were then used in the next practicum. The results showed that the endophytic bacterial isolates were not able to inhibit the fusarium sp. and Phytophthora sp., when using the inhibition percentage formula. This is because the average diameter of the pathogenic fungi colonies in the control treatment (R1) with the average diameter of the pathogenic fungi colonies in the endophytic treatment (R2) has the same size, so that when calculated by the percentage inhibition formula it results in the number 0 which means no. there is a zone of inhibition.

Published: May 2021

Considerando a necessidade de compreender de maneira mais atenta os agentes financeiros e urbanos, neste artigo, examinamos a condição de investidor imobiliário dos fundos de pensão brasileiros. Para tanto, analisamos o portfólio imobiliário dos fundos de pensão brasileiros, reconstituindo as recentes discussões sobre o investimento desse agente em tal classe de ativos e abordando os aspectos regulatórios que circundam suas práticas e alocações. Buscamos, ainda, caracterizar o patrimônio imobiliário dos fundos de pensão: quais os principais canais de investimento utilizados, bem como os segmentos e localizações investidas. A partir dos dados coletados, concluímos que há novos movimentos em favor de investimentos imobiliários conduzidos por meio de veículos financeiros; contudo, esses investimentos possuem características muito semelhantes aos investimentos adquiridos pela compra direta do imóvel comercial. Ambos os canais de investimento – direto e indireto –, como argumentamos, resultam em imóveis para uso comercial (como shopping centers e escritórios), localizados nos estados onde o mercado imobiliário comercial é bem desenvolvido, São Paulo e Rio de Janeiro.

Introducción: en el siguiente artículo se describen los sentidos que asocian al juego y al juguete algunos profesionales de diversas áreas de la salud en el ámbito hospitalario. Objetivo: analizar los sentidos que asocian al juego y al juguete algunos profesionales de diversas áreas de la salud. Materiales y métodos: desde un diseño cualitativo y bajo el método de estudio de caso, se utiliza como técnica de construcción de datos la entrevista semiestructurada para exponer los resultados de la categoría sentidos a partir de dos núcleos de significación teórica: sentido subjetivo autobiográfico y sentido clínico. Resultados: en los hallazgos se pone de manifiesto la manera como el sentido subjetivo autobiográfico de estos profesionales permeó la práctica profesional y se describen algunos sentidos clínicos con relación a la manera como el juego y el juguete permite a estos profesionales formular hipótesis sobre aspectos subjetivos, afectivos, relacionales y comunicativos en los que se apoya un ejercicio diagnóstico, terapéutico o educativo. Conclusiones: estos sentidos se abordan desde dos pilares: la propia infancia de estos profesionales como punto de partida para construir los lazos con el paciente, ya que se evidencia una fuerte conexión entre la propia subjetividad para dinamizar, de manera particular, la relación terapéutica con los niños del hospital y, el segundo, la práctica profesional como experiencia a partir de la cual se configura un sentido para el juego y el juguete.

El mercurio como contaminante y factor de riesgo para la salud humana
Authors: Cadavid-Muñoz Natalia , Arango-Ruiz Álvaro
Published: May 2021

El mercurio (Hg) es considerado en la actualidad un contaminante a nivel mundial, que además impacta de manera negativa sobre la salud de las personas que están expuestas a este. Dentro de sus efectos más graves se encuentran afectaciones a nivel del sistema nervioso, por lo cual se considera un problema de salud pública que requiere la atención adecuada. El mercurio puede entrar al cuerpo a través de la ingesta, inhalación y absorción, por lo cual las poblaciones expuestas a actividades como la minería en pequeña escala representa un factor de riesgo importante sobre el cual se deben establecer estrategias para la mitigación de la exposición al mercurio. Teniendo en cuenta lo anterior, este artículo de revisión presenta los avances y tendencias significativas reportadas por bibliografía indexada, tanto a nivel nacional como latinoamericano e internacional. Las evidencias son claras: la intervención de estrategias de mayor escala es urgente para controlar la contaminación por mercurio de las fuentes de abastecimiento de agua y alimentos y prevenir afectaciones graves a la salud de los seres humanos.

Conclusiones: las técnicas de impresión y los procedimientos de transformación e innovación tuvieron incidencia en la cultura impresa configurando un sistema técnico que privilegió la alfabetización. De esta manera se debe pensar de forma relacional los aportes de las artes gráficas al desarrollo de proyectos editoriales alfabetizadores liderados por el Estadoinstructor a lo largo del período de estudio.
Synthesis, Molecular Structure, Spectroscopic analysis, and Biological activities of new 2,4-Dinitrophenylhydrazone derivatives: A combined experimental, and theoretical study
Authors: Khan Azim , Riaz Muhammad , Jan Faheem , Ullah Arif , Haq Hameed Ul , Khan, Momin
Published: May 2021

The present work focuses on the synthesis and characterization of four
hydrazone derivatives. The structures of the synthesized compounds were
determined through spectroscopic techniques via., EI MS, &1H NMR. The
experimental results demonstrate that the obtained compounds
successfully synthesize and screened for DPPH free radical scavenging
activity, ferrous ion-chelating activity, ferric ion reducing activity,
total antioxidant activity, and hydroxyl radical scavenging activity.
Density Functional Theory (DFT) calculations were carried out by the
Gaussian 09 package by using a hybrid density functional B3LYP (at
6-31G, 6-311G, and 6-31G++(d,p) basis sets) to investigate the
electronic, molecular structures and provide useful spectroscopic and
structural information. The computational data obtained from 1H NMR
calculations were quite compatible with the experimental results. DFT
calculations optimized the molecular geometry and estimated the highest
occupied molecular orbital (HOMO) and lowest unoccupied molecular
orbital (LUMO) energy of these compounds. Additionally, the charge
transfer within the molecule and favorable sites for the electrophilic
and nucleophilic attack was explored. Furthermore, the frontier
molecular orbital (FMO) calculations were used to calculate different
reactivity parameters, i.e., ionization potential, electron affinity,
electronegativity, chemical hardness, chemical softness, and
electrophilicity index.
Rapidly progressive pulmonary fibrosis in COVID-19 pneumonia
Authors: Stjepanovic Mihailo , Belic Slobodan , Buha Ivana , Maric Nikola , Baralic Marko , Mihailovic-Vucinic Violeta
Published: May 2021

Introduction. COVID-19 pneumonia does not have a characteristic course and prognosis. Many facts still remain hidden, mainly why certain patients develop complications with serious tissue damage and whether it causes a permanent organ impairment. If and when will fibrosis develop in COVID-19 pneumonia requires further research, but a link between the amount of tissue afflicted and the development of fibrosis exists. Case outline. A previously healthy, non-smoker, woman with minor symptoms on admission had suddenly developed a serious respiratory insufficiency and whose radiographic finding on computed tomography scan had shown a serious progression with the development of fibrosis in a matter of days. The exact mechanism and correlation of this clinical course remains unknown; however, it is clear that the pulmonary fibrosis is caused by COVID-19 pneumonia. Follow-up computed tomography scan, performed 50 days after initial symptoms, had shown a partial regression of consolidations and post-inflammatory fibrosis. Conclusion. Pulmonary fibrosis is the most severe complication of COVID-19 infection on the respiratory system. Who, when or if a patient will develop any complication is still unclear, as well as whether these changes are reversible? Also, the number of recovered patients who later develop some chronic complications remains to be seen.
Evaluation of self-perceived pain and jaw function impairment in children undergoing slow and rapid maxillary expansion:
Authors: Abed Al Jawad Feras H. , Alhashimi Najah A.
Published: May 2021

Objectives

To evaluate and compare perceived pain and jaw function impairment during the first 4 weeks with slow maxillary expansion (SME) using quadhelix and rapid maxillary expansion (RME) using conventional banded hyrax.

Materials and Methods

Sixty patients aged 10.2 to 15 years were enrolled and consecutively recruited to either the quadhelix group (QG) or hyrax group (HG). A questionnaire was used to evaluate pain, jaw function impairment, and analgesic consumption in the first 7 days, at 2 weeks, and at 4 weeks.

Results

Fifty-five patients (43 girls and 12 boys) completed the questionnaire at all time points (27 in the QG and 28 in the HG). Except at 4 hours, there were no significant differences between the groups regarding pain from teeth, tongue, and palate. Patients started to adapt after day 3. Patients in the HG group reported significantly higher scores for difficulty in swallowing (moderate to severe) during the first 6 days. In both groups, minimal effects were found on speech and the majority of patients did not experience difficulty in yawning or laughing. There was no significant difference in analgesic consumption between the groups. No correlations were found between age, gender, or malocclusion type and any of the investigated outcomes.

Conclusions

Quadhelix for SME and conventional banded hyrax for RME were well tolerated by patients after 1 week. The decision to use either appliance could be based on factors not related to patient experiences.

Regulatory T lymphocytes expressing the forkhead/winged helix transcription factor Foxp3 (Treg) play a vital role in the protection of the organism from autoimmune disease and other immunopathologies. The antigen specificity of Treg plays an important role in their in vivo activity. We therefore assessed the diversity of the T-cell receptors (TCRs) for antigen expressed by Treg newly developed in the thymus of autoimmune type 1 diabetes-prone NOD mice and compared it to the control mouse strain C57BL/6. Our results demonstrate that use of the TCRα and TCRβ variable (V) and joining (J) segments, length of the complementarity determining region (CDR) 3, and the diversity of the TCRα and TCRβ chains are comparable between NOD and C57BL/6 mice. Genetic defects affecting the diversity of the TCR expressed by newly developed Treg therefore do not appear to be involved in the etiology of type 1 diabetes in the NOD mouse.
Clinical Application of Time in Range and Other Metrics
Authors: Aleppo Grazia
Published: May 2021

Time in range (TIR) and other continuous glucose monitoring (CGM)-derived metrics have been standardized in international consensus conferences. TIR correlates closely with A1C; a TIR of 70% correlates to an A1C of 6.7–7%. Evidence is emerging on the association of TIR with long-term diabetes complications, and each 10% increase in TIR shows a substantial decrease in risk for long-term complications. Application of TIR to clinical practice can be easily done with a stepped approach to the analysis and interpretation of CGM-derived metrics and the ambulatory glucose profile report. Clinician education and partnership with patients are crucial for successful implementation of TIR and all CGM-derived metrics in clinical practice.
Time in Range in Pregnancy: Is There a Role?
Authors: Wyckoff Jennifer A. , Brown Florence M.
Published: May 2021

Continuous glucose monitoring (CGM) is being used with increasing frequency as an adjunct to self-monitoring of blood glucose in pregnancy, and novel targets based on CGM data are becoming standardized. This adoption of CGM is the result of its improving accuracy, patient preference, and evolving data demonstrating associations of novel targets such as time in range (TIR) with pregnancy and neonatal outcomes. A greater understanding of the relationship of various CGM metrics to outcomes in pregnancy complicated by diabetes is needed. It is clear that TIR parameters need to be uniquely lower for pregnant women than for nonpregnant individuals. CGM technology is also an integral part of hybrid closed-loop insulin delivery systems. These insulin delivery systems will be a significant advance in the management of diabetes during pregnancy if they can achieve the pre- and postprandial targets required for pregnancy and optimize TIR.

The Anti-Nemic Potential of Mushroom against Plant-Parasitic Nematodes
Authors: WA Elkhateeb
Published: May 2021

Plant-parasitic nematodes are responsible for huge annual economic loss that is estimated to be more than 215 billion US$ worldwide due to plants damages caused by nematodes. The root-knot nematode ( Meloidogyne spp.) is ranked first in the global list of top ten plant-parasitic nematodes, with wide host range of more than 3000 host plant species and posing a major threat in the cultivation of agricultural, vegetables, and horticultural crops. Such pathogens are commonly controlled using chemical nematicides. However, the risk of using such chemicals on human, animals, and surrounding environment has forced researchers to search for natural, less harmful, and effective nematicidal agents. In this review, we discuss the biological control of nematodes by different microorganisms, stressing on the promising capabilities of some mushrooms such as some species of Pleurotus, Beauveria, Ganoderma lucidum and Lentinus edodes.
Keratitis X Acremonium : A Case Report and Literature Review
Authors: Cordeiro Dias Vanessa
Published: May 2021

Purpose: Describe an unusual development of fungal keratitis caused by Acremonium sp in six patients who underwent cataract surgery at an ophthalmology service in Brazil, as well as to report the origin of these infections. Methods: Swabs from the affected corneas were collected to perform culture for bacteria and fungi. These materials were sown in Blood agar (Difco/ USA), Macconkey agar (Difco/USA) and Thioglycolate broth (Difco/USA) for bacterial research and Sabouraud agar (Difco/ USA) for fungi research. A microbiological study was carried out to analyze surgical instruments, the environment and other materials used in the surgeries. Results: Case reports occurred with six patients, all aged over 71 and 85 years, who underwent a surgical procedure for cataract correction by an Ophthalmology service. After surgery, these patients presented loss of unilateral visual capacity, with the formation of a white mass on the cornea. Swabs from the affected corneas were collected to perform culture for bacteria and fungi, in specific culture media. The bacterial cultures showed negative results. Fungal cultures revealed the presence of Acremonium spp. Conclusions: It is likely that Acremonium spores found in the wardrobe were deposited on all the sterile material stored there. At the time of cataract surgeries, this material was unpacked and fungal structures became detached and found in the surgical field of these patients' eyes a gateway. Thus, cleaning and sanitizing measures for surfaces must be implemented and monitored, especially in critical areas such as in hospital areas, in order to avoid damage to patients' health

Authors: Gomes Silmara Cristiane
Published: May 2021

Este trabalho de pesquisa tem como objetivo geral verificar se os Valores Pessoais e Laborais geram conflitos individuais, que podem auxiliar na explicação de ações de consumo hedonistas, e como objetivos específicos: a) identificar se os conflitos individuais, gerados pelas inter-relações entre Valores Pessoais e Laborais, são preditores de ações de consumo. Realizou-se análises estatísticas para a verificação dos objetivos e revisão bibliográfica para possibilitar a compreensão dos elementos que influenciam na inter-relação entre Valores Pessoais e Valores Laborais. Considera-se, ao longo deste trabalho, que o consumo hedonista tem gradativamente se apresentado como uma ação comum aos indivíduos e que os estímulos que o fazem acontecer vêm mudando ao longo dos séculos e que esses múltiplos estímulos devem ser analisados. Aqui, se dedica a uma vertente desses estímulos.
