WITHDRAWN: Combustion stability and flame characteristics of hydrocarbon-air mixtures in millimeter-scale cavity-stabilized burners with proper thermal management
Authors: Chen Junjie 
Published: June 2022

Abstract
Flame stabilization is a common problem in these combustion systems, and a flame will propagate through a fuel-air mixture only when certain conditions prevail. However, the precise mechanism underlying the stabilizing effect of the cavity method remains unclear. This study relates to the thermal management of micro-structured cavity-stabilized burners. The design factors affecting combustion stability and flame characteristics of hydrocarbon-air mixtures in millimeter-scale cavity-stabilized burners are determined. The results indicate that the flow velocity, wall thermal conductivity, channel height, and heat loss are critical factors in assuring combustion stability within the cavity-stabilized burner. The axial heat transfer from the post-flame to the pre-flame via wall conduction widens stability limits and can enable the construction of smaller burners. Axial heat transfer also enhances the benefits of operating under high admixture inlet velocity and wall heat transfer coefficient conditions. Heat exchange through the structure can lead to a broadening of the reaction region, but heat loss to the environment decreases the broadening effect and eventually results in flame quenching. The maximum power density tends to increase with increasing the channel height. Fast flows can cause blowout and slow flows can cause extinction. The anisotropic wall thermal conductivity influences the maximum achievable power density. The channel height has an important effect on the stability and performance of the cavity-stabilized burner and should be included when estimating burner performance.

Abstract
TANGO2-deficient disorder (TDD) is an autosomal recessive genetic disease caused by biallelic loss-of-function variants in TANGO2 gene. TDD-associated cardiac arrythmias are typically recalcitrant to standard antiarrhythmic medications and constitute the leading cause of death. Here, we established novel patient-derived induced pluripotent stem cell differentiated cardiomyocyte (iPSC-CM) models that recapitulate key electrophysiological abnormalities in TDD including prolonged field potential duration, premature ventricular contractions, and decreased spike amplitude. These conduction abnormalities normalize in iPSC-CMs with either adenoviral expression of WT-TANGO2 or correction of the pathogenic variant by CRISPR editing. We further demonstrate that folate greatly abolishes the ventricular ectopy and conduction abnormalities. Data from this study taken together with clinical data from TDD patients supports the use of B-vitamins to mitigate cardiac crisis in TDD patients.

Abstract
Language conversion is a technique that has tremendous use worldwide. With the multitude of languages available, it is not feasible for an average person to learn languages he/she will not use. However, everyone faces situations where knowing a certain language would help in a certain city or even during work. This problem can be solved using the latest technologies in deep learning and computer vision. A system that can identify the text from images and convert them into a well-known language like English has tremendous use everywhere especially in the medical field. The medical field is one where communication and exchange of information is critical. In case of a medical emergency during a tourists visit, the inability to understand what the doctor is trying to say or what type of medication is being prescribed would lead only to more stress and panic. There are systems that have tried to solve this problem and there will be more in the future. One of the glaring issues faced by contemporary systems is the lack of image processing before getting the text of a signboard using computer vision algorithms. Blurred images or images where the characters of the text are too close to each other can hamper the system’s performance to a great extent. The proposed system provides a way by which the text present in an image can be extracted and displayed back to the user in a universal language like English. The system incorporates an optical character recognition tool called pytesseract to get the text from the image and it is converted into a different language using deep learning.

Published: June 2022

Abstract
In this paper, a 9.5 x 9.5 x 1.524mm 3 asymmetrical CPW fed stub loaded hook-shaped patch antenna is proposed. The proposed antenna is mounted on the partial ground with the dimensions of 4.5 x 9.5 x 0.035mm 3 and is excited by a 50-ohm line. A slot of dimensions 2.5 x 2.5mm 2 is etched on the ground plane to achieve a wideband feature for the proposed patch antenna. The antenna consists of a λ/4 ‘L’ shaped stub and a λ/4 vertical stub attached outside the hookshaped patch antenna. The hook antenna resonates at 20.6GHz (simulated) and the stubs help the antenna to radiate at multiple frequencies with proper impedance matching. The ‘L’ shaped stub introduces resonance at 6.96GHz (simulated) and the vertical stub introduces resonance at 11.67GHz (simulated). The proposed antenna has been designed, fabricated, and tested. The measured impedance bandwidth of the ultra-wideband antenna is 33.88GHz (6.12–40GHz). The ultra-wideband feature makes the proposed patch antenna eligible for ultra-wideband and data collection applications. The proposed antenna has gains ranging from 1.1dBi to 5.25dBi. The proposed antenna possesses good radiation features in both E- and H-planes at all the resonant frequencies. Moreover, the proposed antenna is an excellent candidate for Federal Communications Commission (FCC) licensed frequencies, data collection and upper 5G applications. The proposed antenna exhibits better performance compared to the existing ultra-wideband antennas which are discussed in the literature. The measured and simulated results are in acceptable agreement.

La naciente filosofía tuvo en Parménides a uno de sus precursores más célebres y, sin duda, a uno de los que más influyó a todo el pensamiento posterior. En este trabajo, después de presentar sintéticamente nuestra lectura del pensamiento parmenídeo, por un lado, se quieren mostrar las consecuencias que implica esta propuesta filosófica acerca de lo que es el ser y de qué significa pensar Consecuencias que influyen no sólo en el ámbito filosófico, sino que también en el teológico. Por otro lado, en referencia a estos dos alrededores, se intentará elaborar una propuesta distinta acerca del ser y del pensamiento que no recaer en lo que hemos llamado ciertas 'enfermedades del pensamiento' o 'psicopatologías' causadas por el extenso y severo influjo parmenídeo.

Picohydro Power Plant is one of the renewable energy sources which utilizes water or irrigation channels with a small head and flow rate. Many factors can affect the hydrolysis power and also the power on the rotation of the screw turbine, one of which is the turbine design. The existing turbine design needs to be evaluated by several factors such as inner and outer screw diameters, slope, screw pitch, number of blades and condition of inlet and outlet as well as head and water flow. Moreover, if the turbine is designed for a portable one with a length of approximately only 1 meter. These factors indicate that the design of each screw turbine design needs to be optimized through data analysis to find the optimal hydraulic power and turbine rotation. This study aims to determine the effect of the tilt angle of the Archimedes screw turbine on the turbine rotation and also the hydraulic power of the picohydro power plant with variations of the turbine tilt angle (K) 20°, 30° and 40°. The method used in this research is to use a Performance Experiment Study by making an Archimedes screw turbine as a picohydro power plant. From the test results using a discharge of 2 ltr/sec, the largest turbine rotation is 144.3 at a 30° turbine tilt angle with 10.77 Watt of produced hydraulic power (P).

Published: June 2022

Unfortunately, multicultural problems manifested in patterns of thought, attitude, and behavior of intolerance are still seen in many societies over the past decade. It started to become common that certain groups attacked other ethnic and racial groups thereby causing conflict. This might be due to the handling of cases that are not ideal and appropriate, situations of intolerance, and social conflicts that have a wide impact, including causing psychological problems such as anxiety, hatred, violence, or depression. This study aimed to critically examine psychological coping strategies carried out in various countries to assist post-conflict victims with trauma, especially in multicultural societies. This study used an integrative review approach to analyze nine selected articles about psychological strategy and social education for post-conflict settings from 2010 to 2021 by reputable journals or publications. The results showed that the post-conflict victim handling strategy in various countries is carried out using psychosocial approaches and counseling/narrative therapy which are considered the most effective to help victims with trauma. Multicultural skills are an important part of post-conflict psychological handling, and hence is recommended multicultural counseling as a post-conflict psychological treatment and social education model is widely applied by societies with a high level of diversity.

Authors: Lee Sun-Kyung , Cai Qiyue , Basha Sydni , Gupta Aditi , Gewirtz Abigail 
Published: June 2022

Background
The COVID-19 pandemic has increased the stress levels of parents, especially health care workers and other COVID-19 frontline workers. Nonetheless, little is known about stress management for this population.

Objective
This pilot study tested the impact of a mobile app apt.mind in reducing stress in health care provider parents by delivering a 30-day microrandomized intervention.

Methods
Participants included 102 parents who work in health care and their coparenting partners. They were given smartwatches and access to a mindfulness app. Each day, all parents were randomly assigned to (1) brief stress reduction messages, (2) meditation audio activities via the app, or (3) no intervention. Stress was evaluated using a self-reported COVID-19 Family Stressor Screener (10 items; 5-point Likert scale) to rate levels of stress regarding food security, job stability, family conflict, mental health, and social isolation. Dosage was measured by the percentage of parents who received any of the activities (app or messages; mean 66%, SD 9.8%), and parents were divided into 3 groups by dosage level: low (below 60%), middle (61%-70%), and high (above 71%).

Results
Using a pre-post test, this study assessed changes in mental health symptoms and parenting by individuals’ dosage levels. Participants who received high levels of intervention reported significant decreases in COVID-19–related family stress (t=–2.50; P=.02) and a significant increase in parenting efficacy (t=2.39; P=.03), while those who received low or middle levels of the intervention did not show those changes.

Conclusions
This study supports the feasibility and efficacy of technology-based tools to reduce stress and the need to examine just-in-time interventions. Future studies can improve by focusing on microchanges in the parents’ stress level on a daily basis and including physiological data such as heart rate variability to include objective stress data.

Challenges and Perspectives on Plasmid Curing, Medicinal and Pharmacological Traits of Plumbago Zeylanica (Chitraka): A Review
Authors: Rajashree B. Patwardhan  
Published: June 2022

From ancient times of vedas, charaksamhita and sushrutsamhita, to modern day developments and research in medicine, the medicinal importance of Chitraka (Plumbago zeylanica) as a wonderful Indian remedy has been upheld through the test of time. Chitraka is used in ayurveda for relief from many ailments, especially digestive disorders, bronchitis, diseases of liver, leucoderma, inflammation, piles, itching, laryngitis, rheumatism, diseases of spleen, many skin disorders etc. The root extracts of P. zeylanica have been incorporated in various Indian indigenous ayurvedic drug formulations. This paper reviews various aspects of Chitraka like different pharmacological activities, medicinal properties including wound healing, antioxidant, antiulcer, anticancer, leishmanicidal, antifertility, antimalarial, antidiabetic, hypolipidemic, trypanocidal, antibacterial, antifungal, antiviral, anti-inflammatory, antimutagenic, anti-allergic, larvicidal, insecticidal and anxiolytic activities. P. zeylanica plant contains naphthoquinones, flavonoids, terpenes, alkaloids, glycosides, steroids, triterpenoids, tannins, phenolic compounds, glucopyranoside, sitosterol saponins, coumarins, carbohydrates, fixed oils, fats and proteins having a wide variety of bioactivities. The important compound responsible for bioactivity is plumbagin which is chemically 5-hydroxy-2-methyl-1,4-naphthoquinone. Studies of P. zeylanica roots resulted in identification of plumbagin and lawsone as an active principle exhibiting the plasmid elimination activity. Due to the toxicity of chemical curing agents like acridine orange or ethidium bromide, there is a constant need of developing novel curing agents which are more effective and at the same time their non- toxic nature. Bacterial strains resistant to multiple antibiotics have emerged to which the invention of new antibiotics has failed to match up. The effects of antibiotic resistance are serious with mortality and morbidity constantly on the rise. Therefore P. zeylanica root extracts containing lawsone and plumbagin would have great potential as drugs of choice in the treatment of antibiotic resistant bacterial strains. The already ineffective antibiotic therapy can be made effective by converting antibiotic resistant bacteria into sensitive ones. The present review for the first time depicts the use of P. zeylanica as antimicrobial and plasmid curing agent in medicinal formulations and it is a novel approach towards the spread of antibiotic resistance especially in the hospital environment.

Published: June 2022

Background and objectives: The present research is aimed to study the eco-friendly nature and therapeutic application of the natural dye from the seed extract of Bixa orellana for maximizing the benefits of cotton fabric. Materials and methods: A natural dye was extracted from Bixa orellana seeds by hot water and ethanolic extraction method. This dye was examined for its ability with pre-mordanting and post-mordanting of cotton fabrics with ferrous sulphate, hydrated double sulphate and tamarind seed powder in order to improve the aesthetics and natural color shades on cotton fabrics. Furthermore, the dyed cotton fabric was used to analyze the antibacterial efficacy of cotton fabric against bacterial culture such as Bacillus cereus, Escherichia coli, Proteus mirabilis, Salmonella typhi and Klebsiella pneumoniae. Results: Our results suggest that pre- mordanting of cotton fabric with ferrous sulphate, alum and tamarind seed shows good dye fixation rate and stronger color than post-mordanting. Dyeing of cotton fabric with the ethanol extract of Bixa orellana seeds gave excellent and beautiful shades than the ones extracted with hot water. Furthermore, cotton fabric dyed with ethanol extracted was found significantly active against human pathogens compared to cloth dyed with hot water extract. The results evidenced that cotton knitted fabrics showed an increase in dye uptake with natural mordant and strength with a considerable reduction in antimicrobial activity. Conclusion: This research adumbrated developing a greener technology to cabalistic use of Bixa orellana seed extract applied on cotton cloths for coloring and in future find commercial use as a functional finishing agent (for newborns, clothing for burns, injured soldiers and hospitals) for health protection with semi-durable therapeutic properties.

Authors: Alvarado-García Alejandra María , Salazar-Maya Angela Maria 
Published: June 2022

Introducción: El cuidado paliativo se ha convertido en un desafío para los gobiernos por las repercusiones para pacientes, familias y sistemas de salud. La enfermería tiene un rol preponderante en ofrecer una práctica que dé respuesta a las necesidades de los pacientes en situación paliativa, es por este motivo que es necesario avanzar en el análisis de propuestas disciplinares, tal como la de Willis, Grace y Roy, quienes proponen un enfoque central unificador para la disciplina de la enfermería. Metodología: se realizó una revisión exploratoria a través de los siguientes descriptores: cuidado paliativo; enfoque unificador y disciplina de enfermería y sus dimensiones: humanización, significado, elección, calidad de vida y acompañamiento en el proceso de vivir y morir. Al respecto se utilizaron bases de datos, diccionarios, libros de autores icónicos, y páginas de internet relacionadas con la salud en el periodo comprendido entre 2000 y 2020. Se privilegiaron como idiomas el español, el inglés y el portugués. Se analizaron 45 artículos. Resultados: surgieron a partir de las categorías a priori, mencionadas anteriormente, las cuales hacen parte del enfoque unificador disciplinar y que a la vez permiten avanzar en la comprensión de cómo los cuidados paliativos se conciben como parte de ellas, lo que facilitó la reflexión y el avance en propuestas disciplinares desde un componente ontológico. Conclusión: la práctica de enfermería implica aspectos relacionados con: la humanización, el significado, la elección, la calidad de vida y el acompañamiento en el proceso de vivir y morir. Estos aspectos se amplían desde una mirada epistemológica del cuidado, lo que facilita el avance en el entendimiento y en su aplicación. Es prioritario aplicar estos asuntos disciplinares en la práctica del cuidado paliativo, donde la interdisciplinariedad es una necesidad y una realidad.
