Does haste make waste? Prevalence and types of errors reported after publication of studies of COVID-19 therapeutics
Authors: Chatterton Brittany , Ascher Simon B. , Duan Naihua , Kravitz Richard L.
Published: November 2023

Background

The COVID-19 pandemic spurred publication of a rapid proliferation of studies on potential therapeutic agents. While important for the advancement of clinical care, pressure to collect, analyze, and report data in an expedited manner could potentially increase the rate of important errors, some of which would be captured in published errata. We hypothesized that COVID-19 therapeutic studies published in the early years of the pandemic would be associated with a high rate of published errata and that, within these errata, there would be a high prevalence of serious errors.

Methods

We performed a review of published errata associated with empirical studies of COVID-19 treatments. Errata were identified via a MEDLINE and Embase search spanning January 2020 through September 2022. Errors located within each published erratum were characterized by location within publication, error type, and error seriousness.

Results

Of 47 studies on COVID-19 treatments with published errata, 18 met inclusion criteria. Median time from publication of the original article to publication of the associated erratum was 76 days (range, 12–511 days). A majority of errata addressed issues with author attribution or conflict of interest disclosures (39.5%) or numerical results (25.6%). Only one erratum contained a serious error: a typographical error which could have misled readers into believing that the treatment in question had serious adverse effects when in fact it did not.

Conclusions

Despite accelerated publication times, we found among studies of COVID-19 treatments the majority of errata (17/18) reported minor errors that did not lead to misinterpretation of the study results. Retractions, an indicator of scientific misdirection even more concerning than errata, were beyond the scope of this review.

The multisensory mind: a systematic review of multisensory integration processing in Anorexia and Bulimia Nervosa
Authors: Brizzi Giulia , Sansoni Maria , Di Lernia Daniele , Frisone Fabio , Tuena Cosimo , Riva Giuseppe
Published: November 2023

Individuals with Anorexia Nervosa and Bulimia Nervosa present alterations in the way they experience their bodies. Body experience results from a multisensory integration process in which information from different sensory domains and spatial reference frames is combined into a coherent percept. Given the critical role of the body in the onset and maintenance of both Anorexia Nervosa and Bulimia Nervosa, we conducted a systematic review to examine multisensory integration abilities of individuals affected by these two conditions and investigate whether they exhibit impairments in crossmodal integration. We searched for studies evaluating crossmodal integration in individuals with a current diagnosis of Anorexia Nervosa and Bulimia Nervosa as compared to healthy individuals from both behavioral and neurobiological perspectives. A search of PubMed, PsycINFO, and Web of Sciences databases was performed to extract relevant articles. Of the 2348 studies retrieved, 911 were unique articles. After the screening, 13 articles were included. Studies revealed multisensory integration abnormalities in patients affected by Anorexia Nervosa; only one included individuals with Bulimia Nervosa and observed less severe impairments compared to healthy controls. Overall, results seemed to support the presence of multisensory deficits in Anorexia Nervosa, especially when integrating interoceptive and exteroceptive information. We proposed the Predictive Coding framework for understanding our findings and suggested future lines of investigation.
Rehabilitation strategies for managing urinary incontinence in COPD: a review of literature
Authors: Sundus Habiba , Khan Nahid , Mohammad Noor
Published: November 2023

Background

Urinary incontinence (UI) is linked to an increase in social disengagement, fractures and falls, depression, lack of concentration, elevated anxiety, and nursing home admissions, which has a significant negative impact on quality of life and the economy. Respiratory illness is regarded as a risk factor for urinary incontinence as coughing, and dyspnea raises the intra-abdominal pressure and results in an additional strain on the bladder. If the pelvic floor muscles (PFM) are weak, this might then cause leaking.

Methods

A literature search was conducted using multiple databases for physiotherapeutic treatment options for urinary incontinence in COPD for the present review.

Results

A keyword search yielded 9081 articles of which 11 articles were included in the present review according to the inclusion and exclusion criteria.

Conclusion

There is a lack of studies involving both conditions; for treatment, we can combine some physiotherapy interventions of UI with COPD to achieve the desired result and as suitable for the patient.

Authors: Itoda Yoshifumi , Fukushima Toshiya , Kawamoto Shuhei , Shimozawa Motoharu , Tateishi Retsu , Haba Fumiya , Ono Shunya , Nakahara Yoshinori , Kanemura Takeyuki
Published: November 2023

Background

Aspiration of fish bones is common, but perforation of the gastrointestinal tract is very rare. Once perforation occurs, fatal complications such as mediastinitis and cardiac tamponade can occur. Here, we present a case of acute pericarditis due to perforation of a fish bone.

Case presentation

A 66-year-old woman was referred to our hospital with shortness of breath. Blood tests showed high C-reactive protein, and contrast-enhanced computed tomography showed a large amount of pericardial fluid as well as a foreign body with high bone density in the pericardial sac. Upper gastrointestinal endoscopy showed no evidence of penetration of the esophageal or gastric mucosa. Emergency open chest surgery was performed, and the pericardial sac was filled with copious amounts of pus. The fish bone-like foreign body was found to penetrate the pericardial membrane from the diaphragmatic side. The foreign body was removed, a drainage tube was placed, and the chest was closed. After 2 weeks of postoperative antibiotics, the patient was discharged from the hospital in stable general condition. Three months after the surgery, the patient had no recurrence of pericarditis.

Conclusions

We reported a rare case of gastrointestinal perforation by a fish bone, resulting in pericardium, which was treated by surgical drainage.

Published: November 2023

PURPOSE

Childhood cancer survivors are at the risk of developing subsequent colorectal cancers (CRCs), but the absolute risks by treatment modality are uncertain. We quantified the absolute risks by radiotherapy treatment characteristics using clinically accessible data from a Pan-European wide case-control study nested within a large cohort of childhood cancer survivors: the PanCareSurFup Study.

METHODS

Odds ratios (ORs) from a case-control study comprising 143 CRC cases and 143 controls nested within a cohort of 69,460 survivors were calculated. These, together with standardized incidence ratios for CRC for this cohort and European general population CRC incidence rates and survivors' mortality rates, were used to estimate cumulative absolute risks (CARs) by attained age for different categories of radiation to the abdominopelvic area.

RESULTS

Overall, survivors treated with abdominopelvic radiotherapy treatment (ART) were three times more likely to develop a subsequent CRC than those who did not receive ART (OR, 3.1 [95% CI, 1.4 to 6.6]). For male survivors treated with ART, the CAR was 0.27% (95% CI, 0.17 to 0.59) by age 40 years, 1.08% (95% CI, 0.69 to 2.34) by age 50 years (0.27% expected in the general population), and 3.7% (95% CI, 2.36 to 7.80) by age 60 years (0.95% expected). For female survivors treated with ART, the CAR was 0.29% (95% CI, 0.18 to 0.62) by age 40 years, 1.03% (95% CI, 0.65 to 2.22) by age 50 years (0.27% expected), and 3.0% (95% CI, 1.91 to 6.37) by age 60 years (0.82% expected).

CONCLUSION

We demonstrated that by age 40 years survivors of childhood cancer treated with ART already have a similar risk of CRC as those age 50 years in the general population for whom population-based CRC screening begins in many countries. This information should be used in the development of survivorship guidelines for the risk stratification of survivors concerning CRC risk.

Authors: Milliken Don , Al-Kadhimi Samuel , Lim Chung , Rahman Suehana
Published: November 2023

Surgical resection of arteriovenous malformations (AVMs) is indicated in the presence of life-threatening and severe morbidity, including symptomatic heart failure, ischemic pain, and recurrent bleeding, where other less invasive treatment strategies have been unable to halt the progression of disease. We present the challenges encountered in the perioperative care of a 23-year-old man with high output cardiac failure, gangrenous hand, and severe chronic pain undergoing shoulder disarticulation for a high-flow complex AVM of the upper limb.

Published: November 2023

Objective: To compare visual outcomes after cataract surgery using three intraocular lenses (IOL) of different prices but similar properties.

Methods: A comparative study with retrospective data of patients operated for phacoemulsification with monofocal IOL implants was carried out at Al-Ibrahim Eye Hospital (AIEH) from April 2021 to Feb 2022. Patients with diabetes, any preoperative ocular morbidity and unclear diagnosis were excluded from the study. Pre and post-operative best corrected visual acuity (BCVA) on 1st day, 7th day and 4-6 weeks were analyzed. IOLs were categorized on the basis of price into economical, standard and premium lenses. To minimize surgical bias, data was further stratified on the basis of surgical expertise.

Results: Data of 3237 patients was analyzed. Economical lens (A) was implanted in 2647, standard (B) in 254 and premium (C) in 336 patients. On average BCVA (6/6 to 6/12) was achieved in 88.2% of patients. No significant difference was found at third follow up among BCVA of three IOls operated by senior surgeon, χ2(2) = 3.216, p = 0.20, with median (IQR) is 0.2(0.2) logMAR for Group-A, 0.1(0.2) logMAR for Group-B and 0.2(0.1) logMAR for Group-C. When results of the rest of the surgeons was considered, significant difference was found among BCVA at 3rd followup, χ2(2) = 6.661, p = 0.036, with median (IQR) is 0.3(0.2) logMAR for Group-A, 0.2(0.1) logMAR for Group-B and 0.2(0.3) logMAR for Group-C.

Conclusion: When surgical factors mainly, surgeon bias is removed, all three types of monofocal IOL had similar visual outcomes.

Authors: Herardi Ryan , Djajawiguna Hafidz Naeriansyah , Wahyuningsih Sri , Kshanti Ida Ayu , Medina Shahnaz , Praditya Lingga Etantyo
Published: November 2023

Background Diabetic patients are always in contact with medical sharps, such as pen needles, lancets, and syringes. Sometimes, patients improperly dispose of these items and cause needle stick injuries. This study aimed to identify factors that improve appropriate manner in which individuals with diabetes who require insulin therapy dispose of medical sharps. Methods In December 2019, a cross-sectional investigation was undertaken amongst insulin therapy-dependent diabetic patients visiting Jakarta’s Fatmawati General Hospital. A questionnaire was formulated to appraise medical sharps’ disposal methodology. The data gathered from the said patients, including their age, gender, educational level, employment status, length of time as a diabetic, duration of insulin treatment, and receipt of formal medical training, were also recorded. Results Of 103 diabetic patients, 77.3% were over 50 years old, 58.3% were female, 68% were a low level of education, 74.8% were not working, 84.5% were diagnosed with diabetes for more than 5 years, 53.4% were using insulin therapy for more than 5 years, and only 65% had got formal training on medical sharp products disposal. Nearby 83.5% still recap the pen needle insulin with the inner needle cap after injecting insulin, and 92.2% still threw medical sharps on the street when traveling outside. Approximately 81.6% of respondents stored their unused needles and lancets in a secured manner that was inaccessible to children. The practice score for proper medical sharps disposal increased from 4.5 to 6.0 as a result of formal training provided by healthcare professionals, as determined by the Mann Whitney Test (p=0.001). Conclusions Formal training by healthcare workers was the only factor that improved medical sharp products disposal practice among diabetic patients using insulin therapy.
Monte Carlo Simulation for the Frequency Comb Spectrum of an Atom Laser
Authors: Schelle Alexej
Published: November 2023

A theoretical particle-number conserving quantum field theory based on the concept of imaginary time is presented and applied to the scenario of a coherent atomic laser field at ultra-cold temperatures. The proposed theoretical model describes the analytical derivation of the frequency comb spectrum for an atomic laser realized from modeling a coherent atomic beam of condensate and non-condensate quantum field components released from a trapped Bose–Einstein condensate at a given repetition phase and frequency. The condensate part of the atomic vapor is assumed to be subjected to thermal noise induced by the temperature of the surrounding thermal atomic cloud. This new quantum approach uses time periodicity and an orthogonal decomposition of the quantum field in a complex-valued quantum field representation to derive and model the quantum field's forward- and backward-propagating components as a standing wave field in the same unique time and temperature domain without quantitative singularities at finite temperatures. The complex-valued atom laser field, the resulting frequency comb, and the repetition frequency distribution with the varying shape of envelopes are numerically monitored within a Monte Carlo sampling method, as a function of temperature and trap frequency of the external confinement.Quanta 2023; 12: 171–179.
Rekonstrukcja strategii Stanów Zjednoczonych wobec Tajwanu podczas prezydentury Josepha Bidena
Authors: Grzegorzewski Filip
Published: November 2023

RECONSTRUCTING THE US STRATEGY TOWARDS TAIWAN DURING THE PRESIDENCY OF JOSEPH BIDEN
Adopting the model of neoclassical realism and elements of the American-centric nationalist paradigm, the paper examines both systemic factors stemming from the Sino-American power rivalry and internal ones referring to the populist traditions of American foreign policy. The main goal of America regarding Taiwan was to use its relationship with the island in its policy of containment of China by emphasizing Taiwan’s right to decide its future and preventing China from taking over the island by force. Along with deepening bilateral cooperation, the administration used multilateral mechanisms to promote the concept of peace and security across the Taiwan Strait as an essential element of the global order, which increased the number of countries interested in maintaining the status quo. Russia’s aggression against Ukraine heightened concerns about the possibility of PRC’s attack on Taiwan, prompting the Biden administration to intensify pressure on Taipei to accelerate military reform. However, the accentuation of closer relations between Washington and Taipei was interpreted by China as a provocative crossing of more “red lines,” leading to an intensification of repressive measures against Taiwan and the consolidation of bellicose rhetoric directed against both Washington and Taipei.
Nowe konteksty w polityce Polski, Czech i Litwy wobec Tajwanu w następstwie agresji Rosji na Ukrainę
Authors: Przychodniak Marcin
Published: November 2023

NEW CONTEXTS IN THE POLICY OF POLAND, THE CZECH REPUBLIC AND LITHUANIA TOWARDS TAIWAN FOLLOWING RUSSIA’S AGGRESSION AGAINST UKRAINE
The article presents the actions of Poland, Lithuania and the Czech Republic towards Taiwan in the context of Russian aggression against Ukraine over the course of last year. Although each of these countries supports the subjectivity of Taiwan in the face of the political escalation of China’s activities, their reaction is varied, especially with regard to further relations with the People’s Republic of China. At the same time, each of the countries recognizes the importance of developing relations with Taiwan in the face of US policy, as well as the continued involvement in supporting Ukraine or strengthening NATO’s eastern flank. Therefore, no significant changes should be expected in these countries’ approach to Taiwan, although Lithuania and the Czech Republic will be among the strongest promoters of, for example, a greater involvement of the EU in relations with Taiwan.

TIC en la calidad de vida de jóvenes universitarios: un modelo integral desde el enfoque de capacidades
Authors: Zermeño Flores Ana Isabel
Published: November 2023

Desde los enfoques de capacidades y de las tecnologías de información y comunicación como medios para promover el desarrollo humano, nos preguntamos ¿cómo estas pueden incidir en la calidad de vida de jóvenes universitarios? Como innovación, validamos un modelo que vincula las variables: medios-tic, factores de conversión, capacidades, funcionamientos, fines de vida y satisfacción con la vida, relacionándolas con las particularidades de esta población. Aplicamos una encuesta por cuotas a seis universidades públicas del norte, centro, oriente, occidente y sur de México, obteniendo datos de 3629 jóvenes. Mediante modelos estructurales confirmamos que el modelo empírico es robusto, dado que la mayoría de las relaciones funcionales entre variables son significativas. Además, a través del análisis de clúster bietápico, derivamos una tipología de capacidades de jóvenes universitarios, en la que la formación y ocupación de madres y padres, el nivel de marginación municipal y la universidad de procedencia son altamente significativos. Concluimos que, aunque estas tecnologías sí aportan a la calidad de vida de estos jóvenes, no son decisorias; en cambio, sus capacidades (libertad, autonomía y oportunidades del entorno) son las que impulsan los usos, aprovechamiento y regulación de sus prácticas tecnológicas.

Published: November 2023

O aumento do fluxo migratório haitiano para o Brasil a partir de 2010 está associado a crises política, econômica e às catástrofes ambientais. O acesso à saúde pelos imigrantes é o Sistema Único de Saúde no Brasil que tem como porta de entrada a Atenção Primária à Saúde. O objetivo deste trabalho foi relatar a experiência dos cuidados em saúde aos imigrantes haitianos em uma Unidade Básica de Saúde Guará no Distrito Federal. Métodos: Trata-se de um relato de delineamento observacional e descritivo do cuidado em saúde voltado aos imigrantes haitianos pela equipe de saúde e os residentes em medicina de família e comunidade. Resultados: A população de imigrantes haitianos é estimada de 60 indivíduos assistidos pela equipe de saúde da família. A busca pelo cuidado é feita, em sua maioria, mulheres e crianças e as demandas em saúde são voltadas para saúde da mulher e da criança. Os desafios dos cuidados em saúde são relacionados a barreiras de comunicação e às diferenças culturais. Conclusão: O relato desta experiência demonstra que processos de integração e adaptação culturais podem colocar em conflito normas sociais, valores e costumes, havendo necessidade de conhecimento do território e articulação por parte da equipe de saúde. Visto que o SUS presta assistência a imigrantes, faz-se necessária a abordagem das equipes de saúde, bem como o planejamento de ações que levem em conta a influência da cultura na expressão dos sintomas, na experiência da doença, bem como na evolução do quadro clínico.

Este trabalho tem como objetivo relatar a experiência de estagiários do curso de Fisioterapia de uma universidade pública brasileira, durante a pandemia de COVID-19, a partir do telemonitoramento ou teleconsulta de mulheres submetidas ao tratamento oncológico mamário ou com incontinência urinária. Os atendimentos foram guiados por roteiro orientador construído pelos estagiários, sob supervisão docente. Foram realizadas vídeo-chamadas via Whatsapp ou Google meet, entre os meses de julho a outubro de 2020. Após cada encontro virtual, aplicou-se a Escala de Alcance de Metas (Goal Attainment Scaling) para verificar a satisfação da voluntária em relação ao atendimento. Para cada estagiário solicitou-se, ao final das ações, a produção de narrativa a fim de conhecer as percepções em relação às barreiras e potencialidades do atendimento remoto. Vinte mulheres com média de idade de 57 anos foram acompanhadas, e destas, 18 apresentaram queixas referentes ao tratamento oncológico (dor em ombro/membro superior; edema; aderência cicatricial e alteração de sensibilidade) e duas tiveram queixas relacionadas à perda urinária. A média de número de atendimentos no período para cada participante foi de 7,7; e o escore médio da Escala de Alcance de Metas foi de 1,63 (classificado como melhor que o esperado). A ausência de habilidade das mulheres para manuseio do aparelho celular foi percebida pelos estagiários como barreira para os atendimentos. Entretanto, eles também observaram que este modelo de cuidado tem potencial para, mesmo após a pandemia, continuar a ser realizado, principalmente com indivíduos com doenças crônicas.

O projeto Abebê: Cuidando e Promovendo a Saúde das Mulheres de Axé durante a pandemia do Covid-19 teve de reduzir suas atividades nas comunidades de axé, assim foi necessário utilizar estratégias para levar informações de prevenção sobre a nova doença. O objetivo deste estudo é relatar a experiência com o uso de vídeos educativos publicados em mídias sociais digitais como estratégia de ofertar informação sobre a COVID-19 para as comunidades de axé. Trata-se de um estudo descritivo, do tipo relato de experiência. Foram desenvolvidos nove vídeos educativos sendo cada um representado por uma orixá feminina, trazendo informações atuais sobre o auto cuidado e diversas formas de prevenção a nova doença. Todos os vídeos possuem uma linguagem simples para ampliar o alcance a todas as faixas etárias, classes sociais e regionalidade das populações de axé do Brasil. Os roteiros tinham como base explicar: o que é o COVID-19 e quando surgiu; como a doença se espalhou pelo mundo até chegar no Brasil; instruções de como montar e usar máscaras faciais caseiras; higienização das mãos, objetos e superfícies; quais os sintomas, cuidados e o que fazer em caso de contaminação; quais são os grupos de risco e as principais medidas preventivas a serem tomadas. Essa estratégia foi exitosa pois conseguimos ampliar o acesso as novas informações sobre a pandemia a outros estados e novas comunidades.
A extensão universitária em uma perspectiva de discentes de cursos das áreas tecnológicas

Published: November 2023

Este artigo apresenta um diagnóstico sobre como discentes extensionistas de cursos das áreas tecnológicas compreendem a extensão universitária e suas diretrizes, a saber: dialogicidade; interprofissionalidade, indissociabilidade entre  ensino, pesquisa e extensão;    impacto    na    formação    do    estudante    e    impacto    na  transformação social. Para realização do trabalho foram analisadas 40 respostas de estudantes que participaram de ações de extensão no ano de 2020. Os estudantes responderam um questionário composto por perguntas objetivas e um campo para comentários. Todos os respondentes eram alunos de uma unidade acadêmica de cursos das áreas tecnológicas de uma universidade pública brasileira, situada no interior de Minas Gerais. As respostas foram agrupadas em nove blocos conforme organização do questionário, estruturado de forma pregressa à sua aplicação. Os resultados sugerem que a prática efetiva da dialogicidade ainda é um grande desafio para os estudantes, embora a comunicação seja de grande preocupação para os respondentes. Buscar desenvolvimento pessoal e técnico é uma das principais motivação para a participação de ações de extensão, apesar do foco no impacto na transformação social. Melhorar a comunicação deve ser um dos objetivos da gestão da extensão universitária, pois os meios institucionais não alcançam sequer a comunidade acadêmica, ainda que as redes sociais tenham ampliado esse alcance.
Subindo o Morro Boa Vista para Plantar: uma nova forma de engajamento socioambiental?
Authors: Rocha Jéssica Raposa , Teixeira Marcos
Published: November 2023

Em um cenário urbano, é um desafio construir uma relação entre jovens e o meio ambiente. A Educação Ambiental (EA) se insere como uma alternativa no desenvolvimento de adultos com uma consciência ambiental nutrida durante sua formação. Partindo de uma visão de ressignificação do espaço urbano como parte do meio ambiente, este trabalho buscou usar uma ação de reflorestamento de área degradada em meio ao tecido urbano (Morro Boa Vista, Niterói, RJ), como uma ferramenta de engajamento de jovens de 16 a 24 anos em ações de cunho socioambiental, com o viés de reapropriação de áreas verdes e, consequentemente, da valorização do serviço ambiental prestado por estes espaços. Jovens moradores das comunidades do Preventório, Cavalão, Morro do Estado, Morro do Arroz, São José, Vital Brazil e Souza Soares participaram de atividades coordenadas por alunos do Programa de Educação Tutorial de Engenharia Agrícola e Ambiental da Universidade Federal Fluminense (UFF) durante o período de janeiro a março de 2021. A realização de atividades práticas, que convidam os participantes a “colocarem a mão na massa” (plantio de mudas) e o uso de ambientes alternativos (diferentes das usuais salas de aula) se mostraram como pontos assertivos no engajamento. Além da percepção de se ver como agente de transformação da sua realidade, a divulgação das ações nas mídias sociais pelo próprio público alvo das ações se revelou como a maior fonte de pertencimento, pois há um reforço positivo do seu empenho na preservação do meio ambiente percebido a partir do compartilhamento de sua participação com seu próprio grupo social.

RESOLUCIONES PROVISIONALES. EL CONTROL DE OFICIO DE LOS PRESUPUESTOS PROCESALES
Authors: Mosmann María Victoria
Published: November 2023

El sistema procesal argentino está compuesto por una legislación federal y un Código Procesal Civil y Comercial por provincia. Las medidas cautelares no se encuentran reguladas en ninguno de los Códigos Procesales Civiles vigentes en Argentina, ni en ninguno de los planes de reforma de los Códigos Provinciales. Sin embargo, es posible analizar este instituto en relación con las figuras que sí se encuentran reguladas en el país, tales como las medidas cautelares, las medidas autosatisfactivas, las sentencias anticipadas, la ejecución provisional de sentencias, las acciones preventivas y el proceso monitorio. El artículo buscó conceptualizar las medidas cautelares; compararlas con las medidas cautelares previstas en el Código Procesal Civil de Brasil de 2015; analizar las figuras e instituciones existentes en el sistema procesal del Código Procesal Civil y Comercial de la Nación de Argentina, especialmente en lo que se refiere a los requisitos legales; las pretensiones que pueden formularse; el ejercicio de la contradicción; la competencia del tribunal, la legitimación de las partes y la posibilidad de interponer recursos. En el sistema procesal argentino, pueden caracterizarse como aquellas tutelas jurisdiccionales que resuelven de modo transitorio y no definitivo alguna pretensión (o algunas o todas), tanto de modo autónomo como incidental, tanto para los casos de tutelas de urgencia o de evidencia. El Código Procesal Civil y Comercial de la Nación, vigente en el país, regula las medidas cautelares en los artículos 195º a 237º y no prevé ninguna otra forma de tutela que pueda catalogarse como provisional. Las técnicas anticipatorias pueden neutralizar los efectos del tiempo en el proceso y el código y las leyes especiales han creado los más diversos procedimientos anticipatorios, lo que hace difícil identificar un aspecto general de la técnica anticipatoria en Argentina. Las técnicas específicas de desagravio sumario deben ser compatibles con los principios que definen el modelo de juicio justo. “Hacer bien” y “hacer pronto” deben ser articulados para asegurar el mejor y más efectivo rendimiento de la tutela jurisdiccional. Se concluye que, si bien las medidas cautelares no se encuentran reguladas bajo esta denominación en Argentina, sí se encuentran previstas en el Código Procesal Civil y Comercial de la Nación, las cuales deben ser controladas de oficio por el juez, especialmente en lo que respecta a la competencia del tribunal y a la legitimación de las partes, ya que el derecho de defensa se encuentra más limitado en dichos institutos.

Published: November 2023

In teaching, students' representations could constitute an obstacle to the construction of scientific knowledge and are often considered stable cognitive structures whose organization is sought to be inferred through questionnaires and interviews. This study aims at identifying and analyzing high school students’ representations related to the concept of biodiversity. To meet this objective, a semi-structured interview and a questionnaire were used to collect data. 202 Moroccan students participated in this survey (46.5% from rural areas and 53.5% from urban areas of the "Direction Provinciale" of education of Guelmim city in Morocco). The results of the interview indicated that only 1.82% of the students gave a definition that consists of the three biodiversity dimensions, namely the species, the ecosystems, and the genetic diversity. The questionnaire results revealed a low to medium correlation between their representations and their acquired knowledge related to the concept of biodiversity dealt with in Moroccan school programs (from the discipline of "scientific activity" in the primary cycle and that of "life and earth sciences" in the secondary cycle). The results further indicated a low presence of supervised activities related to biodiversity within the school and therefore a low degree of influence on the students' representations. It was concluded that there was no effective transmission or adequate assimilation of the concept of biodiversity among the students surveyed.

Dr ying is an essential process for preserving agricultural products. Most natural biological compounds are sensitive and easily degraded under drying conditions. This study investigated the effects of drying temperature (40, 50, 60, and 70°C), air velocity (0.05, 0.10, 0.15, and 0.20 m/s), and feed amount (0.60, 0.80, 1.00, and 1.30 kg/m2) on the moisture ratio, drying rate, mitragynine (MG) content, and specific energy consumption (SEC) of kratom leaves. The results showed that temperature, air velocity, and the quantity of kratom leaves significantly affected the drying process. The drying kinetics of kratom leaves were best explained by the Midilli-Kucuk model. The R2, reduced χ2, SSE, and RMSE values of the Midilli-Kucuk model under hot air drying varied from 0.9965 to 0.9993, 0.000075 to 0.000358, 0.001124 to 0.007869, and 0.007692 to 0.01740, respectively, for kratom leaves dried at 40, 50, 60, and 70°C. The MG content of dried kratom leaves at 40°C was the highest at 10.10 mg/g. The lowest SEC values, which corresponded to the highest amount of MG in the dried leaves, were achieved at a drying temperature of 40°C, an air velocity of 0.2 m/s, and a kratom leaves feed amount of 0.60 kg/m2.

In order to reduce the negative impact of waste glass and urban heat on the environment, this research aims to use waste glass cullet as an aggregate in concrete paving blocks. This work aims to produce porous pavement using two sizes of waste glass and ordinary Portland cement (OPC). Two layers of paving blocks with different aggregate sizes were planned. The first part of the work was to determine the best OPC content. The results showed that the largest aggregate-based porous paving block had the highest compressive strength and acceptable permeability. Then, designed porous block (DPB) was designed, which consisted of two layers, with the upper layer consisting of small aggregates and the lower layer consisting of large aggregates, and cement mortar (80 wt% cement powder and 20 wt% glass powder) was used as the binder. Compressive strength and permeability were the criteria. The pavement can release heat better than conventional pavements and is safe because of the skid resistance, which meets the criteria.

A second-or der RC equivalent circuit model was established to improve the estimation accuracy of state of charge (SOC) of power Li-ion batteries, and the model parameters were identified by the recursive least square method with forgetting factor (FFRLS). On this basis, an adaptive cubature kalman filter (ACKF) algorithm was proposed to adaptively modify the process noise covariance matrix and the measurement noise covariance matrix to improve the SOC estimation accuracy. Finally, the SOC estimation algorithm was verified by MATLAB simulations. The results show that compared with UKF and CKF algorithms, the proposed algorithm has higher estimation accuracy and robustness, and can meet the application requirements.

An amperometric bi-enzyme biosensor based on α-chymotrypsin (CHY) and alcohol oxidase (AOX) was developed for detection of aspartame in a flow injection analysis (FIA) system. The CHY and AOX were separately immobilized on bead supports using an adsorption technique. The cleavage of aspartame was catalyzed by CHY to produce methanol that was converted by AOX to formaldehyde and hydrogen peroxide. The formed hydrogen peroxide was detected amperometrically at a platinum electrode. The biosensor performance was optimized with respect to enzyme immobilization and operating conditions. The most suitable conditions for enzyme immobilization were 250 U/mL CHY and 100 U/mL AOX with 60 min immobilization time. The optimal conditions for operating the developed aspartame biosensor were a flow rate of 0.5 mL/min and pH 8.0 at an applied potential of +0.70 V versus Ag/AgCl. Under the optimal conditions, the developed biosensor showed a linear response over the aspartame concentration range 0.15–1.0 mM (coefficient of determination (R2) = 0.9941) with a sensitivity of 5.52 μA/mM·cm2 and a detection limit of 0.10 mM. The developed biosensor was successfully applied in the determination of aspartame in commercial samples.

Published: November 2023

A convolutional neural network (CNN) is designed and trained to partially control a dual-band, large uniform rectangular array of reconfigurable radiating elements. The CNN selects the number of active elements and switch states needed to achieve a desired beam shape. Both pattern multiplication and finite element method (FEM) are used to simulate the radiation patterns of a PIN-diode square-spiral antenna array. After training on radiation pattern images of arrays calibrated for both phase and gain imbalance and mutual coupling, the CNN achieves 97 percent validation accuracy. Then, using the resulting size and switch states, the patterns are simulated with and without mutual coupling using the pattern multiplication model and FEM, respectively. The mean beam steering and 3-dB beamwidth errors without mutual coupling are less than 5.5 degrees and up to 12.3 degrees with mutual coupling.

This paper proposes a method to add an additional phase compensation to conventional phased arrays to achieve flat-topped beam forming, which can convert the spherical waves emitted by common conical horn antennas into cylindrical flat-topped beams, at the same time, there is also a certain power enhancement. A centrosymmetric unit composed of four layers of F4B and metal patches is designed. By changing the value of the parameters, a 360∘ phase change can be achieved, and it has the advantages of small size and low-profile. To validate the design concept, a prototype of the transmitarray (TA) was designed, fabricated, and measured by calculating the phase distribution of the front. The measurement results show that the designed TA can achieve flat-topped beams at 5.2GHz, the maximum gain is 1.15dB higher than that of the horn antenna, and the flat-topped range is about ±10∘. The results are in good agreement with the simulation within the test range.

Published: November 2023

In this paper, a circularly polarized printed monopole antenna (CPPMA) is proposed for medical microwave imaging and health monitoring applications. The proposed CPPMA is optimized to operate at the Industrial, Scientific and Medical (ISM) band. A prototype of the designed antenna is fabricated and printed on the low-cost FR-4 substrate that has a compact size of 34 × 28 × 1.5 mm3. The simulated results indicate that the designed CPPMA operates between 2.425 GHz and 2.475 GHz while the measured results range between 2.32 GHz and 2.515 GHz. The designed CPPMA also reveals a circular polarization performance at 2.45 GHz (2.4386 GHz - 2.4633 GHz). The suitability of CPPMA for microwave imaging is confirmed by checking its aptitudes to detect the presence of breast tumors and brain strokes. A great detection capability is achieved for breast tumors and brain strokes of various sizes inserted at different positions with a high sensitivity to changes or anomalies in the dielectric properties of human tissues. In addition, the usefulness of the proposed CPPMA for wearable application is justified experimentally. Excellent agreement is achieved between the simulated results and the measured ones.

Published: November 2023

A circularly polarized microstrip antenna array with low side lobe levels is proposed for Vehicular Satellite Communication. The suppression of side lobe levels is accomplished by the non-uniform power distribution utilized to feed the individual patch elements. Impedance matching is ensured by the incorporation of a quarter-wave transformer via a microstrip line fed to the edge of the patch. When the proposed amplitude-weighted feed is compared to the conventional corporate feed, simulation results indicate a reduction in side lobe levels of 8.9 dB. The proposed antenna is constructed out of RT/DUROID 5880 material, which is lighter, more flexible, and less expensive than ceramic materials. The radiation characteristics of the proposed antenna are compared when the antenna is planar versus when it is made to conform to the roof of the vehicle. The measured results indicate a reflection coefficient at the resonant frequency of -31.5 dB and -27.7 dB when conformal, an impedance bandwidth of 410 MHz and 180 MHz when conformal, an axial ratio bandwidth of 140 MHz and 170 MHz when conformal, and a peak gain of 15.719 dB and 14.335 dB when conformal. The measured results validate the simulation results that this proposed antenna is appropriate for a variety of Vehicular Satellite Communication applications.
Performance of Ṭhumrī in Kathak Dance
Authors: Shah Purnima
Published: November 2023

Abstract: During the eighteenth century, Lakhnau, the capital of the royal state of Awadh, emerged as the refined center for the arts. Over the next centuries, kathak maestros and elite tavāifs (soiree singers and dancers) enthralled patron connoisseurs with their exquisite ṭhumrī performances, receiving lavish rewards. Ṭhumrī exemplified an aesthetic synthesis of the devotional (bhakti) and worldly themes based on undifferentiated love situated in the śṛṅgāra rasa (amorous, erotic sentiment). This essay is an attempt to highlight the infinite performative possibilities improvised by the dancer through imaginative interpretations of the ṭhumrī song-text and the connoisseur spectator’s interactive response in culturally specific meaning-making. Ṭhumrī performance epitomized the poetic “nāyikā,” who dominated prolific classic and regional literature over the millennia.
