Published: September 2024

La investigación aborda el impacto económico en el sector turístico, de la pandemia por Coronavirus COVID-19 en las micro y pequeñas empresas (MYPES) de la población de Bacalar, Quintana Roo. En este documento se plantea la hipótesis de que estas empresas presentaron un decremento en la afluencia de turistas y como resultado de dicho decremento, la disminución de sus ingresos y la disminución de su capacidad para solventar sus gastos, sus pasivos y sus obligaciones. Esta investigación es descriptiva, utilizando como técnica de recolección de datos, un cuestionario integrado por 15 reactivos de opción múltiple, aplicado a una muestra de 47 empresas ubicada en Bacalar dentro de la zona centro y costera de esta población. El resultado obtenido es que efectivamente estas empresas, sí sufrieron afectaciones debido a la pandemia, ya que más de la mitad presentó una disminución en la afluencia de turistas y en la demanda de productos y servicios que son ofrecidos por las mismas, dando como resultado un decremento en su flujo de efectivo. Esto provocó que se implementen las medidas necesarias para afrontar este escenario, como la disminución de la jornada laboral y como consecuencia la disminución del salario a los trabajadores, entre otras.

Published: September 2024

This paper reports on the design, fabrication, and temperature strain sensing performance of a fiber Bragg grating composite structure for surface mounted temperature measurements over a wide temperature range, with highly reduced strain cross-sensitivity. The fiber Bragg grating sensor is encapsulated in a polyimide tube filled with epoxy resin, forming an arc-shaped cavity. This assembly is then placed between two layers of glass fiber prepreg with a flexible pad in between and cured into shape. Experimental results, supported by finite element simulations, demonstrate an enhanced temperature sensitivity is 26.3 pm/ºC over a wide temperature range of -30℃ to 70℃, and high strain transfer isolation of about 99.65%.

Abstract
The periodic coronal rain and in-phase radiative intensity pulsations have been observed in multiple wavelengths in recent years. However, due to the lack of three-dimensional coronal magnetic fields and thermodynamic data in observations, it remains challenging to quantify the coronal heating rate that drives the mass cycles. In this work, based on the MURaM code, we conduct a three-dimensional radiative magnetohydrodynamic simulation spanning from the convective zone to the corona, where the solar atmosphere is heated self-consistently through dissipation resulting from magnetoconvection. For the first time, we model the periodic coronal rain in an active region. With a high spatial resolution, the simulation well resembles the observational features across different extreme-ultraviolet wavelengths. These include the realistic interweaving coronal loops, periodic coronal rain, and periodic intensity pulsations, with two periods of 3.0 hr and 3.7 hr identified within one loop system. Moreover, the simulation allows for a detailed three-dimensional depiction of coronal rain on small scales, revealing adjacent shower-like rain clumps ∼500 km in width and showcasing their multithermal internal structures. We further reveal that these periodic variations essentially reflect the cyclic energy evolution of the coronal loop under thermal nonequilibrium state. Importantly, as the driver of the mass circulation, the self-consistent coronal heating rate is considerably complex in time and space, with hour-level variations in 1 order of magnitude, minute-level bursts, and varying asymmetry reaching ten times between footpoints. This provides an instructive template for the ad hoc heating function and further enhances our understanding of the coronal heating process.
Anti-Shakespeare shrews: Women, sexism, and talking back to the Bard in Upstart Crow and All Is True
Authors: Semple Edel 
Published: September 2024

Ben Elton's Upstart Crow (2016–18) is a popular BBC sitcom about Shakespeare's early years as a writer, while Elton's All Is True (2018) is a somber biopic about Shakespeare's retirement to his family home in Stratford-upon-Avon. Elton's biofictions place a fictionalized historic Shakespeare in direct contact with female antifans—his wife, daughters, and female friends—to broach the contemporary concern of gender equality. In each of Elton's texts, antifans expose Shakespeare's sexism and investment in the patriarchal status quo. However, despite the depth of the antifans' antipathy, Shakespeare antifandom sometimes emerges as ambivalent. A third text, teen comedy St. Trinian's 2: The Legend of Fritton's Gold (2009), centers its plot on Shakespeare and his antifans but offers a different spin on both.
Irish Shakespeare performance (faraway, so close!)
Authors: McHugh Emer 
Published: September 2024

I use Irish Shakespeare performance as a locus to interrogate how we negotiate and maintain cultural proximities and anxieties about what we term real, authentic Shakespeare in performance. Through archival research, I use Druid Theatre Company's early productions of Shakespeare plays—Much Ado About Nothing (1980–81) and As You Like It (1999)—to show how Irish Shakespeare performance occupies a nebulous position between traditionalism and iconoclasm, as well as between a desire to adhere to and to break a specific mold of performance tradition.
Comparing the effects of three local anaesthetic agents on cardiac conduction system - A randomised study
Authors: Agarwal Vaishali , Das Pravin K. , Nath Soumya S. , Tripathi Manoj , Tiwari Bhuwan 
Published: September 2024

Background and Aims:
This study aimed to compare the effects of three local anaesthetic (LA) agents, namely bupivacaine, levobupivacaine, and ropivacaine, on the cardiac conduction system as assessed by corrected QT (QTc) and P wave dispersion (PWD) intervals in lower limb orthopaedic surgeries and to find the most suitable LA agent that can be used for a long duration.

Methods:
The study included 75 patients with American Society of Anesthesiologists physical status I and II of either gender in the age group of 18–65 years undergoing elective lower limb orthopaedic surgeries under epidural anaesthesia. These were allocated to groups B (bupivacaine), L (levobupivacaine), and R (ropivacaine). We observed blood pressure, heart rate, respiratory rate, PWD, and QTc intervals from baseline value through Holter monitoring, pain assessment by visual analogue scale, and demand and total volume of LA consumed by patient-controlled analgesia devices. The repeated measures of ANOVA were carried out to find the effect of time and time-to-group interaction among the groups across the periods.

Results:
On intergroup comparison of QTc and PWD, no significant difference among groups was observed, but on intragroup analysis, a statistically significant increase in QTc and PWD from baseline was observed for each of groups B, L, and R at all time intervals. However, the mean increase in QTc and PWD recorded for Group B was higher than in groups L and R.

Conclusions:
Bupivacaine has the maximal tendency to prolong QTc and PWD. All three agents showed comparable haemodynamic effects and time to onset of sensory and motor blockade.

Authors: Mathew Roshni M. , Gautam Shefali , Raman Rajesh , Rai Anurag , Srivastava Vinod K. , Singh Manish K. 
Published: September 2024

Background and Aims:
Precise airway management is vital in thoracic surgeries to ensure patient safety and optimal outcomes. Choosing the correct double-lumen tube (DLT) size is challenging, as it typically relies on height, gender and subjective experience. This study investigates using ultrasonography (USG) and computed tomography (CT) to measure cricoid cartilage diameter for objective DLT sizing.

Methods:
In a randomised study, 120 adult patients undergoing elective thoracic surgery were randomised to three groups: Group A (DLT size determined by USG), Group B (DLT size determined by CT) and Group C (DLT size determined by conventional methods based on height and gender). The primary outcome variable was the appropriateness of DLT size. Secondary outcome variables were the degree of lung collapse and sore throat. Student’s t-test and ꭓ2 test were used to analyse continuous and dichotomous variables, respectively.

Results:
DLT sizing based on cricoid cartilage diameter improved the accuracy, with inappropriate sizes found in 25% in the conventional group, 5% in the USG group and 2.5% in the CT group (P < 0.05). Lung collapse was better in the USG (excellent in 92.5%) and CT (95%) groups compared to the conventional group (70%) (P < 0.05). Moderate sore throat was higher in the conventional group (37.5%) compared to the USG (5%) and CT groups (7.5%).

Conclusion:
The study demonstrates that USG- and CT-guided measurements of cricoid cartilage diameter are reliable and effective methods for determining DLT size in thoracic surgery compared to conventional methods.

Aedes aegypti is the primary vector that causes dengue virus (DENV) infection. Ae. aegypti resistance to abate (Temephos) has occurred in Indonesia and several other countries. Innovations are needed to develop alternative ingredients that can be used as natural larvacides. The Plumeria acuminate L. is an Indonesian plant with metabolites that have the potential to act as larvicides. This study aims to determine the potential combination of ethanol extract of P. acuminate L. leaves and flowers as a larvicide for A. aegypti. A laboratory experimental study with a post-test-only control group design was carried out on Ae. aegypti larvae instar III. The larvicide test was carried out according to WHO standards in 2005 with concentrations of 10000, 7500, 5000, and 2500 ppm, as well as control (water and 1% DMSO), with 20 larvae for each concentration. The observation was carried out at the 24th and 48th hours with 3 repetitions. Larval mortality data was analyzed using one-way ANOVA statistical tests to determine significant differences and lethal concentrations (LC50 and LC90) were calculated using probit analysis using SPSS software. The mortality of Ae. aegypti larvae due to the administration of a combined ethanolic extract of P. acuminate L. leaves and flowers was the highest at doses of 10000 and 7500 ppm, which was 100% with lethal concentrations of LC50 and LC90 of 3364.715 and 6293.759 ppm at the 24th hour observation, whereas at the 48th-hour observation, lethal concentrations were detected at 1767.998 and 2941.138 ppm, respectively. One-way ANOVA analysis test showed a significant difference in Ae. aegypti larval mortality due to the administration of a combined ethanol extract of P. acuminate L. leaves and flowers at 24th-hour observation (p = 0.000) and (p = 0.013) at 48th hour observation. The combination of ethanol extract of P. acuminate L. leaves and flowers showed larvicidal activity against Ae. aegypti larvae as evidenced by larvae mortality which were influenced by concentration and observation time.

Study of Dependence of the Energy of the Field in Weakly Conductive Fiberlight-Guide with Gradient Refractive Index Profile Without Regard to Polarization
Authors: Vlasenko Victor D. , Gladkikh Vyacheslav A. 
Published: September 2024

A round-in-cross-section weakly guiding fiber optic light guide is considered. The system of Maxwellian equations for electrically conductive transparent media without due regard to polarization with an index of refraction in the case under consideration is reduced to the homogeneous Helmholtz equation, a particular solution of which is found using the Green's function. For a unimodalmode a common decision was obtained for the field and energy inside the fiber in the general case of a gradient refractive index profile depending on the radial coordinate. The concept of normalized energy is introduced as the ratio of the energy inside a fiber with gradient refractive index profile to the energy inside a fiber with a step-index profile. Since in a single-mode regime the zero-order Bessel function, which describes the field inside a step-index profile fiber, can be replaced by a Gaussoid, then, when extending this replacement to the case of a single-mode gradient fiber, as a first approximation we shall obtain a finite expression for the normalized energy for a general gradient profile. The dependences of the normalized energy on the waveguide number were obtained for each of the degrees from the first to the fourth inclusive. It is shown that in the considered approximation, the energy increases up to a certain parameter values (for the first degree – a triangle profile) or slowly decreases (other profiles), after this value the energy increases for all profiles. The results obtained will help to select a suitable single-mode fiber for practical application.

Parresia e Arte Autista: Caminhos para a Coragem da Verdade e o Cuidado de Si
Authors: Carvalho Ana Cândida Nunes 
Published: September 2024

O presente artigo parte das arguições sobre os caminhos para o alcance da liberdade parresiasta de uma pessoa autista, no âmbito do cuidado de si, diante das questões impostas pelo cotidiano, evidenciando, nessa perspectiva, as manifestações artísticas desenvolvidas como via para a coragem da verdade. Visa, porquanto, o alcance de uma autoria de si, dentro da descoberta e na instauração de si mesmo como realidade ontológica distinta do corpo, a partir da emergência do conceito de psykhé, como maneira de ser e maneira de fazer de que se trata de dar conta ao longo de toda a existência, erigindo enquanto mola propulsora para traçar o percurso para uma autoria de si, ou seja, para o ser humano retomar a vida como beleza possível, até minimizar os resquícios do sistema de dominação dos sujeitos. Nesse sentido, a discussão resvala nas conceituações que delimitarão o quadro social em que pessoas autistas estão inseridas, como porta de entrada para propor possibilidades do agir, pautadas, ainda, na necessidade de mitigar preconceitos ou obstáculos ao processo de inclusão em todos os âmbitos do cotidiano. O embasamento bibliográfico se concentra em elementos da obra foucaultiana Coragem da verdade, além de alguns de seus comentadores.
