Authors: Sambyal Ananya , Dogra Naina Kala , Ranjan Shivani , Sharma Rishabh , Blouria Bhanu Pratap Singh
Published: December 2023

Background:

There is a change in the pattern and prevalence of acquired syphilis due to better awareness, surveillance, laboratory diagnosis, and treatment in India in recent years. However, restrictive measures for COVID-19 may produce different effects on incidence.

Aims and Objectives:

We aimed to study the changing trend of acquired syphilis in relation to COVID-19 outbreak in a tertiary care hospital in North India.

Materials and Methods:

A retrospective analysis of all the cases of sexually transmitted infections (STIs) was done from January 2016 to June 2022. Demographic, clinical, and laboratory data of acquired syphilis were recorded and analyzed for changing trends in prevalence, clinical presentations, association with HIV and other sexually transmitted diseases (STDs), and its relation to COVID-19. Statistical analysis was done using SPSS software.

Results:

A total of 1105 patients attended STD clinic from January 2016 to June 2022, of which 216 patients were venereal disease research laboratory and Treponema pallidum hemagglutination assay positive (19.5%). Before COVID-19, there was an increasing trend of acquired syphilis (late latent). Patients diagnosed with syphilis pre- and postlockdown did not differ significantly in their mean age, median age, male/female ratio, and HIV status. However, there is an increase in number of cases of primary and secondary syphilis postlockdown which was statistically significant.

Conclusion:

Restrictive measures for COVID-19 during the lockdown produced a declining trend of syphilis. It is unclear whether the observed decrease in number of STI cases was due to true decline, inadequate testing, underreporting, or avoidance of high-risk sexual activities. The upsurge in the number of cases of acquired syphilis after lockdown suggests the possibility that lockdowns did not completely disrupt STI transmission.

Authors: Adavala Mallikarjuna , Reddy K Chandrasekhar , Sadangi Shakambari , Bhattacharya Kausik
Published: December 2023

Aim:

The aim of this study was to estimate the spinal column dose for spinal Stereotactic body radiation therapy (SBRT) before patient treatment using the PTW dosimetry Octavius dose-volume histograms (DVH) four-dimensional (4D) feature.

Materials and Methods:

Twenty-three patients were included in the study, and a volumetric modulated arc therapy plan with 6MV flattening filter-free (6FFF) was generated for each patient in the Eclipse planning system using the Anisotropic Analytical Algorithm (AAA) algorithm (Varian Medical Systems, Palo Alto, CA) for the TrueBeam STx LINAC machine. The Octavius 4D system was used to estimate the spinal cord dose by delivering the plans to the 4D phantom. The measured dose was compared with the Eclipse treatment planning system (TPS) (Varian Medical Systems, Palo Alto, CA) dose.

Results:

The spinal cord max and mean doses estimated using Varisoft DVH 4D are in close agreement with the TPS calculated max and mean doses. The deviation between measured dose and TPS dose is ±5% for the spinal max dose, and the deviation between measured dose and TPS dose is ± 3% for the spinal mean dose.

Conclusions:

The study demonstrates that the PTW Octavius 4D phantom and DVH 4D feature can be used as a tool to estimate spinal cord dose before the treatment in spinal SBRT plans. The system provides an independent dose measurement that is comparable to the TPS dose. The close agreement between measured and calculated doses validates the use of this system as a critical organ dose verification tool.

Authors: Zhong Yi , Wang Jiahe , Li Hang , Yang Siyuan , Li Xiang , Gao Heng , Chen Gang
Published: December 2023

Background:

Calcitonin gene-related peptides (CGRP) have been considered a new effective means to prevent and treat migraine. Eptinezumab is a new class of CGRP antagonists that has been ratified for clinical treatment. The purpose of this systematic review was to assess and contrast the therapeutic effect and safety of eptinezumab in the management of migraine in comparison with a placebo.

Materials and Methods:

We systematically searched PubMed, Embase, Cochrane Library, and the US National Institutes of Health Clinical Trials Registry from the earliest date to February 16, 2023, for randomized controlled trials (RCTs). The mean difference (MD) and risk ratio (RR) were chosen to assess clinical indicators.

Results:

In total, there were 2, 739 patients in four RCTs, who were ultimately included. Our summarized results showed that eptinezumab had better healing efficacy compared to placebo with respect to monthly migraine days (MD = −1.56, 95% conﬁdence interval [CI]: −2.32, −0.79, P < 0.001), improving ≥75% migraine responder rate (RR = 1.80, 95% CI: 1.40, 2.33, P < 0.001), ≥50% migraine responder rate (RR = 1.46, 95% CI: 1.33, 1.61, P < 0.001), and 100% migraine responder rate (RR = 2.41, 95% CI: 1.08, 5.38, P < 0.001). Furthermore, compared with placebo, there was no significant increase for treatment-related adverse events (RR = 1.01, 95% CI 0.94, 1.10, P = 0.71) and serious AEs (RR = 0.93, 95% CI 0.46, 1.90, P = 0.84). It was found that all dosages except for 10 mg had significant efficacy compared with placebo, especially 300 mg (P < 0.001).

Conclusion:

Eptinezumab has good healing efficacy and insignificant adverse effects in treating migraine, particularly the dosage of 300 mg.

Authors: Demirelli H. , Isler Y. , Yuce Yilmaz Kemal
Published: December 2023

INTRODUCTION: Notetaking is considered, by many educators, as one of the critical actions of learning. There are several note-taking methods and approaches. Based on these methods and approaches, various applications, whether mobile, desktop or -Web-based, were developed.OBJECTIVES: In this paper, a novel note-taking application based on Cornell Technique, is presented. Its development process and user acceptance trend are exhibited and results for user evaluation based on user satisfaction are presented. METHODS: For the software development process, Incremental Model was adopted. Requirement Analysis included, aside from examining principles and related note-taking structure of Cornell Technique, investigating (i) how to perform notetaking as an activity of learning, (ii) its product and (iii) relationship of notes for the purpose of storage. Models containing sub-activities, such as reviewing note have been identified and some were selectively adopted and related functions such as review alert (tickler) and collaboration on notetaking have been implemented. To the purpose of storage, a tree-based scheme called collection was modelled. User interfaces were first designed as mockups and click-through pro-totype using Adobe XD. The mobile application was implemented in Dart programming language. Google’s Firebase Service and Flutter Framework was adopted. The mobile application was compared with its equivalents in the Google Play Store and user statistics were investigated. To evaluate perceived usability, the System Usability Scale is adopted and applied to 14 university students conforming to determined persona.RESULTS: The application has been published in Google Play Store for users to install for free on 18th March 2022. As of 10th September 2023, total number of downloads is 5K and the Cornell Note mobile app is currently installed on 1108 devices. For the last three-month period (from 11th June to 10th September 2023), the active users per month changed in an increasing trend from 450 to 589. The average engagement time on 11th of April 2023 was 28 minutes 00 seconds. As the number of monthly active users increased, the average engagement time measured on 10th September 2023 decreased to 23 minutes 31 seconds. However, engagement rates measured were 76.91% and 77.19%, respectively. The mean SUS score was found to be equal to 79.5.CONCLUSION: The user statistics and comparison with equivalent mobile applications reveal that Cornell Note has potential to grow as a mobile application for notetaking since it has a good perceived usability, however, there is room for improvement. Considering any extra marketing effort was not spent for the application such as application store optimization, the statistics are another evidence for user appeal and acceptance. However, it is important to add new functionality without complicating the user experience so that user appeal and acceptance boosts.

Published: December 2023

People are liable to the tax rate if they transfer digital assets during a specific fiscal year. There is no distinction between income from businesses and investments or between short-term and long-term gains because the 30% tax rate is applicable regardless of the sort of income. By clearly stating how it would be charged, the Indian budget 2022 has provided some direction. Losses were consequently experienced by both new and old cryptocurrency buyers. Under Section 115 BBH, it is illegal to offset cryptocurrency losses with cryptocurrency gains—or any other gains or revenue, for that matter. The implementation of the 30% tax rule on digital assets has caused the collapse of the cryptocurrency market, and there is a possibility that investors will continue to suffer losses in the future.

This research article seeks to lay out an extensive understanding of the defined Yolo algorithm, its architecture, and its impact on real-time object detection. This detection will be identified as a regression problem by frame object detection to spatially separated bounding boxes. Tasks like recognition, detection, localization, or finding widespread applicability in the best real-world scenarios, make object detection a crucial subdivision of computer vision. This algorithm detects objects in real-time using convolutional neural networks (CNN). Overall this research paper serves as a comprehensive guide to understanding the detection of objects in real-time using the You Only Look Once (YOLO) algorithm. By examining architecture, variations, and implementation details the reader can gain an understanding of YOLO’s capability.
Case Report: Cardiovascular Manifestations due to Flea-Borne Typhus
Authors: Olivo-Freites Christian , Davar Kusha , Gallardo-Huizar Oscar , Vijayan Tara , Younes Ramee
Published: December 2023

Flea-borne typhus is a vector-borne disease caused by Rickettsia typhi that occurs worldwide, except in Antarctica. In the United States, most cases are restricted to California, Hawaii, and Texas. The syndrome is characterized by nonspecific signs and symptoms: fever, headache, rash, arthralgia, cough, hepatosplenomegaly, diarrhea, and abdominal pain. Although flea-borne typhus can cause pulmonary, neurological, and renal complications, the cardiovascular system is rarely affected. We present a case of endocarditis resulting from flea-borne typhus diagnosed by blood microbial cell-free DNA testing that required valve replacement and antibiotic therapy for 6 months. In addition, we review 20 cases of presumed and confirmed cardiovascular manifestations resulting from flea-borne typhus in the literature.
Combustion Optimization of a Premixed Ultra-Lean Blend of Natural Gas
and Hydrogen in a Dual Fuel Engine Running at Low Load
Authors: Rinaldini Carlo Alberto , Scrignoli Francesco , Savioli Tommaso , Mattarelli Enrico
Published: December 2023

The numerical study presented in this article is based on an automotive diesel
engine (2.8 L, 4-cylinder, turbocharged), considering a NG–H2 blend
with 30 vol% of H2, ignited by multiple diesel fuel injections. The
3D-CFD investigation aims at improving BTE, CO, and UHC emissions at low load,
by means of an optimization of the diesel fuel injection strategy and of the
in-cylinder turbulence (swirl ratio, SR). The operating condition is 3000 rpm –
BMEP = 2 bar, corresponding to about 25% of the maximum load of a gen-set
engine, able to deliver up to 83 kW at 3000 rpm (rated speed). The reference
diesel fuel injection strategy, adopted in all the previous numerical and
experimental studies, is a three-shot mode. The numerical optimization carried
out in this study consisted in finding the optimal number of injections per
cycle, as well as the best timing of each injection and the fuel mass split
among the injections. The analysis revealed that combustion can be improved by
increasing the local concentration of the more reactive fuel (diesel): in
detail, the best strategy is a two-shot mode, with SOI1 = −35°CA AFTDC and SOI2
= −20°CA AFTDC, injecting 70% of the total diesel fuel mass at the first shot.
As far as the SR is concerned, the best compromise between performance and
emissions was found for a relatively low SR = 1.4. The optimization permitted to
extract the full potential of the H2 enrichment in the DF
H2/NG–diesel combustion also at low loads: in comparison to the
DF NG case, combustion efficiency, and gross indicated thermal efficiency have
been improved by 45.7% and 61.0%, respectively; CO- and UHC-specific emissions
have been reduced by about 85.0%. Comparing CDC to the optimized DF 30 vol%
H2/NG–diesel case, soot emissions are completely canceled,
CO2-specific emissions have been reduced by approximately 42.0%,
NOx-specific emissions by 33.8%. However, further work has to be
done in order to reach comparable values of HC and CO, which are still higher
than in a standard diesel combustion.
Flown Away: Eva Bezwoda’s Life, Death and Poetry
Authors: Kowalska Eva
Published: December 2023

Eva Bezwoda was a prominent poet in the 1960s and 1970s, who contributed to several South African journals, as well as publishing One Hundred and Three Poems in 1973. Her death by suicide three years later seems congruen with the themes and preoccupations of her work, and was a loss to South Africa’s literary culture at the time. Despite critical attention to her work, after her death her legacy seems to have been forgotten, and her poetry neglected. In this article, I outline what is known of her biography, with a focus on her most productive years as a writer, and the development of her career in relation to recurrent motifs, prominent themes, and relevant details from her poems. I consider the critical reception of her work and engage with archival material, including correspondence from the year before her death with Ad Donker and personal responses to her death by Sheila Fugard and Lionel Abrahams.
Przeciwdziałanie nudzie za wszelką cenę, czyli disneylandyzacja muzeów – wprowadzenie do analizy zagadnienia w ujęciu praktycznym
Authors: Wańczyk Aleksandra

Tekst opisuje zjawisko, jakim jest wdrażanie komercyjnych rozwiązań w muzeach, których funkcjonowanie co do zasady nie jest nastawione na osiąganie zysku. Nazywana disneylandyzacją tendencja do urozmaicania oferty edukacyjnej niesie ze sobą ryzyko zaniku autonomii tych jednostek i może kolidować z pierwotną misją muzeów, które powinny skupiać swoją działalność na upowszechnianiu zbiorów oraz realizowaniu ustawowo przyjętych założeń, wśród których szczególne miejsce zajmuje ekspozycja i ochrona zasobów i ich odpowiednie magazynowanie. Współcześnie stawia się także duży nacisk na edukację oraz prowadzenie działań aktywizujących muzealną publiczność w oparciu o te zasoby.

Countering Boredom at All Costs – Disneylandization of Museum: Introduction to the Issue in Practice: Text describe phenomenon of implementing commercial activities implemented to museums – non-profit places. Tendency called disneylandisation is attractive, but involves a loss of individual autonomy. Moreover, it may interfere with the mission of museums, which should focus their activities on the dissemination of collections, implementation of statutory objectives and their appropriate storage display units. Nowadays, there is also a strong emphasis on education and conducting activities to activate the museum audience based on these resources.
Perú: cuatro décadas de contienda popular
Authors: Arce Moisés
Published: December 2023

Como la tinta derramada sobre el papel, la contienda popular se va extendiendo en forma de marchas, paros y plantones. Esa extensión, aparentemente homogénea, aglutina fuerzas de distintas intensidades, que solo se dimensionan cuando se detalla quién protesta, contra quién, cómo, dónde y por qué. De tales datos se ocupa este libro, al sistematizar la Base de Protestas Sociales del Perú (1980-2020). En esta compilación se presenta la contienda popular de los actores laborales y sociales durante los periodos de crisis y los de reforma económica. Al mismo tiempo se sitúa el debate en torno a la deficiente calidad de la democracia y el gobierno peruanos, y a cómo la protesta deviene en recurso trascendental para la rendición de cuentas. A la comunidad académica interesada en la acción colectiva en Perú y en América Latina, estas páginas le aportan una perspectiva novedosa basada en el método de análisis de eventos de protesta. Una reflexión para redimensionar esas tonalidades que connotan la contienda popular.

Published: December 2023

Adders are widely used as essential parts in the design of digital integrated circuits. The Carry Select Adder (CSA) is unique among conventional adder topologies in that it operates quickly. There is a need for speedier arithmetic units as well as ones that use less power and take up less space as the mobile sector grows quickly. The Carry-Select method for adder design with carry propagation achieves a good trade-off between performance and cost. However, because it uses two ripple carry adders (RCA), the traditional CSA design still has a significant area overhead. A Binary to Excess-1 code converter (BE-1 converter) has been used in the development of a modified CSA design to overcome the issue. This study presents a practical method for reducing the size and power footprint of the CSA by introducing gate-level changes to the BE-1 converter design. Making use of this alteration, a 4-bit CSA architecture with a BE-1 converter is developed and contrasted with the industry standard CSA design. These designs are evaluated considering their area and power characteristics. The analytical results show that the suggested CSA structure is better than the traditional one and that using a CSA with a BE-1 converter is an efficient way to create a VLSI design.

O presente trabalho é um recorte da dissertação “Candomblé e Ensino de História: o terreiro como um local de ensino-aprendizagem - O caso do Ilé Axé Tobi Babá Olorígbin (2013-2020)”, defendida em 2022 no Programa de Pós-graduação em Ensino de História da Universidade Federal de Uberlândia (PROFHIS). Neste texto, discutimos como o Ensino de História e os saberes tradicionais da cultura afro-brasileira podem ser importantes no espaço da sala de aula. Para realizar análise, nos apoiamos em entrevistas orais de professores da rede básica e superior, bem como nas reflexões de Quintana (2016) e McLaren (2014). Entendemos que a forma de se aprender e ensinar dentro do Candomblé, que traz aspectos das culturas africanas das quais ele descende, é bem diferente do que é colocado nas escolas hoje em dia, com um currículo predominantemente eurocêntrico e capitalista. O Candomblé também se relaciona com o dinheiro, mas por uma perspectiva diferente.Palavras-chave: Cultura Popular e Saberes Tradicionais. Candomblé e Ensino, Ancestralidade.

Authors:   Goa College of Hospitality and Culinary Education, Goa India, D’Souza Dr. Edgar
Published: December 2023

This research paper delves into the critical intersection of green hotel practices and Sustainable Development Goals (SDGs) within the context of India. Focusing on four SDGs—Clean Water and Sanitation (SDG 6), Affordable and Clean Energy (SDG 7), Responsible Consumption and Production (SDG 12), and Climate Action (SDG 13)—the study explores the perceptions of environmental management representatives in India’s four and five-star hotels. Through a comprehensive analysis of survey data from 32 participants, the research uncovers a multifaceted landscape where proactive engagement with green practices is evident. Key findings reveal that hotels in India have a commendable commitment to environmental sustainability, actively aligning with these SDGs. Notable practices include the adoption of energy-efficient technologies, waste reduction and responsible waste management, and proactive steps in climate change mitigation. However, challenges persist, particularly concerning the limited adoption of renewable energy sources, such as solar and wind power. This study offers a nuanced perspective on the hotel industry’s contribution to SDGs, underscoring both commendable achievements and areas for further improvement. The findings hold valuable implications for policymakers, hoteliers, and sustainability advocates, emphasizing the industry’s pivotal role in achieving global sustainability objectives.

Objective: This work aimed to establish histological changes in the structure and activity of the liver caused by experimental obstructive cholestasis. Method: Several methodological approaches were used such as experimental, biochemical, and comparison were applied.Results: It was possible to describe the essence of such a disease as cholestasis and its impact on the liver. At the same time, it was proved that recanalization with incomplete recovery of bile outflow was possible due to the normalization of the total bilirubin (TB) level. Morphological changes in the liver were most pronounced during acute cholangitis. The study examined what processes occur in the body during the recovery of bile flow, including after the complete blockage of such organs as the liver and bile ducts. Consequently, signs that expressed the abnormality of the liver structure of animals were revealed.

Hannah Arendt explica José J. Veiga
Authors: Nepomuceno Luís André
Published: December 2023

Em Origens do totalitarismo (1951), Hannah Arendt propôs considerações decisivas sobre um dos mais complexos modelos políticos do nosso mundo contemporâneo: o totalitarismo, surgido entre as duas guerras e movido pelos estados fascista e comunista. Nesse ensaio, Arendt mostrou que, diferentemente das tiranias e das ditaduras, o totalitarismo conta com o apoio das massas, num projeto que visa sequestrar a consciência do indivíduo em favor do regime político. Essa distinção entre o totalitarismo e a ditadura é altamente reveladora para se compreender a diferença entre o indivíduo submetido à opressão ditatorial e o indivíduo cooptado pelo regime totalitário, sistema que decreta a morte da identidade de quem dele participa. A relação é essencial para se entender a obra do escritor brasileiro José J. Veiga, especialmente em seus romances do chamado “ciclo sombrio”: A hora dos ruminantes (1966), Sombras de reis barbudos (1972), Os pecados da tribo (1976) e Aquele mundo de Vasabarros (1982). Nessa sequência de livros, Veiga investiga os diversos modelos de autoritarismo, considerando que, para além da questão totalitária em si, o autor vivenciou o período da ditadura militar no Brasil. Este artigo busca trazer as conceituações formuladas por Hannah Arendt sobre os diversos modelos de política autoritária e compreender como elas funcionam no “ciclo sombrio” de Veiga.
Exercício de compreensão do mundo em Hannah Arendt:
Authors: Ferrarini Giopato Natália
Published: December 2023

O presente artigo tem como mote o lugar do pensar em Arendt e se propõe a articular algumas noções e conceitos da pensadora ligadas ao seu esforço e exercício de compreensão do mundo e sua busca de sentidos para os fenômenos existentes. Aqui, trabalha-se com o entendimento que a inclinação da autora por tentar compreender as coisas e assim fazer uma leitura mais alargada da realidade vincula-se à sua trajetória pessoal e acadêmica. Como respaldo biográfico, repousamos nossa atenção em Hannah Arendt, for love of the world (1982), de Elisabeth Young-Bruehl. Ademais, destaca-se o referencial dos Escritos judaicos (2016), tendo sido selecionado como recorte possível de análise, o artigo Paz ou armistício no Oriente Médio, escrito em 1948, de modo a contemplar os esforços de Arendt ao pensar a questão judaica ante as problemáticas de seu tempo. Pensando a questão judaica e o momento histórico a ela vinculados, não há como separá-los da própria história de Arendt, que acompanhou a formação do Estado de Israel e o recrudescimento das tensões na Palestina. Qual era o lugar dos judeus? Nesse questionamento buscamos angariar um espaço de discussão que observe a importância que a pensadora atribui à esfera pública, à ideia de ocupação política, entre outras noções similares, como profundamente atreladas à sua condição judaica.

The ability to think critically is an important skill to be acquired, especially at tertiary level. Nonetheless, it has been found that tertiary students’ level of critical thinking (CT) skills to be at the moderate level. An effective level of CT skills has been proven to be beneficial in navigating real-world challenges. Thus, this study is an attempt to answer these research questions: i) What is the perceived level of CT skill among ESL students?, ii) Is there any significant mean difference in the level of CT skills between male and female students?, iii) Is there a significant mean difference in the level of CT skills between LG240 and LG243 programmes?, and iv) Is there any significant mean difference in the level of CT skills among students with different grades?. This study employed a fully quantitative approach and cross-sectional study as its research design. A questionnaire was distributed for approximately three (3) weeks, and 107 responses were received. The data obtained showed that the students perceived their level of CT skills to be at a high level and they had positive views towards their level of CT skills. Moreover, there was no significant difference between genders and programmes, but there were significant differences between grades. Hence, it is important for educators to know their students’ level of CT skills as to prepare suitable lesson plans and materials to develop and enhance this set of skills. For future research, this study would suggest focusing on the development of materials that would assist both educators and tertiary students in developing a good set of CT skills.
Tipología del agente de la Guardia Civil que se suicida

El suicidio es un grave problema de salud pública, que parece estar incrementándose tanto a nivel internacional como en España. Se trata de un fenómeno complejo, de etiología multifactorial, que ha sido muy estudiado con enfoques epidemiológicos y descriptivos, para identificar indicadores de riesgo y de protección que ayuden a prevenirlo, implementando intervenciones efectivas. Asumiendo que las personas que se suicidan no conforman un grupo homogéneo, se sabe que hay colectivos particulares que presentan mayor incidencia, por lo que las estrategias preventivas deben adaptarse a esa diferente casuística. Más aún, incluso dentro de las profesiones, se ha comprobado que el suicidio tampoco es homogéneo, encontrándose por ejemplo diferentes subgrupos o tipos suicidas en la población militar (Griffith, 2012). Las Fuerzas y Cuerpos de Seguridad (policías) constituyen uno de esos colectivos especiales, debido al mayor estigma relacionado con la salud mental, el fácil acceso a medios letales (armas de fuego), y la exposición laboral constante al trauma (accidentes graves, violencia, abusos graves o muerte). Pero no se conocen trabajos que hayan estudiado si existen diferentes perfiles de suicidas entre los agentes. Aquí se presenta el primer estudio tipológico que se ha realizado en España al respecto, analizando datos de 640 agentes de la Guardia Civil que se suicidaron entre 1982 y 2022. Mediante análisis de correspondencias múltiples, de clúster bietápico y bivariantes sobre 16 variables sociodemográficas, profesionales y del hecho en sí, emergieron tres grupos claramente diferenciados. Estos resultados se discuten a los efectos de su utilidad preventiva.
