MATHEMATICAL MODEL OF A NEURON. DERIVATION OF THE BASIC PSYCHOPHYSICAL LAW FOR THE RECEPTOR LEVEL
Authors: Fokin Sergey
Published: April 2024

The proposed study is devoted to the creation of a mathematical model of a neuron that encodes the intensity of a stimulus by the frequency of action potentials. The model was tested with step-shaped impacts of different amplitudes and different natures: constant electric current, constant voltage and natural stimulus; in all cases, typical “force-time” curves were obtained, equidistant to the experimental ones. Application of the model to the conditions of a psychophysical experiment made it possible to derive a system of analytical equations of the basic psychophysical law for the receptor level. Using the proposed model, the “saturation effect” and “crossover” behavior of the “stimulus-sensation” curves identified in psychophysical experiments in individuals with different group characteristics of the nervous system are easily explained. The calculation results showed that individual psychophysical differences are determined by the types of combinations of physiological properties of primary receptor neurons. The publication is intended for neurophysiologists, psychophysicists, psychophysiologists and psychologists, and will also be of interest to compilers of textbooks in these disciplines.

Causal Mediation Analysis for Childhood Cancer Survival Disparity in Texas, 2005 to 2014
Authors: Niaz Morshed , Russell Weaver , F Benjamin Zhan
Published: April 2024

This study aimed to examine the disparities of childhood cancer survival among different racial and ethnic groups in Texas. The analysis was mediated by socioeconomic status (SES) and spatial accessibility to Children Oncology Group (COG) hospitals. The relationship between race-ethnicity and overall survival was measured using the Cox proportional hazards model with a robust variance estimator. The counterfactual model measures the total effect of race-ethnicity on survival through all mediating pathways while adjusting for baseline confounders (age, sex, and stage at diagnosis), which are then decomposed into natural direct and indirect effects. Considering all cancer site groups, African Americans showed a statistically significant higher hazard ratio in death (HR = 3.63; 95% CI = 1.87 - 6.62) compared with non-Hispanic White children. At the same time, the mortality hazard ratio among Hispanic children is not significant (HR = 1.23; 95% CI = 0.80 - 1.93) when compared with non-Hispanic White children. Analysis results also suggested that both mediators significantly contribute to racial-ethnic survival disparities for specific cancer site groups such as Leukemia for African American children. This study builds knowledge and understanding about underlying factors (mediators) responsible for the disparities in the outcomes among childhood cancer patients.
Effect of low microwave temperature on the physical and chemical properties of waste activated sludge
Authors: Alhraishawi Ali , Aslan Sukru
Published: April 2024

In this study, the effect of microwave (MW) irradiation at a target temperature of 80 °C with a heating rate of two °C/min and a holding time of five minutes on the physicochemical properties of activated sludge was studied. The results showed that subjecting biosludge to MW pretreatment resulted in a reduction in particle size to 14.5, 44.6, and 72.8 for d10, d50, and d90, respectively and an increase in the specific surface area of the biosludge to 235.9 m2/kg. Pretreatment resulted in an increase in soluble oxygen demand, sugar, and protein concentrations to 2,380.0 mg/L, 66.5 mg/L, and 1.81 g/L, respectively. A slight increase in the release of inorganic compounds, especially NH4-N and PO4-P, was observed in the disintegrated biosludge. While there was an increase in release of K and Zn, a decrease in concentrations of Na, Ca, Mg, and Al in the liquid was observed after MW irradiation. It was determined that the dewatering property deteriorated after biosludge disintegration, as it increased from raw sludge to disintegrated sludge by 21-fold.
“Ingenio”: análisis histórico de una habilidad del pensamiento
Authors: Farfán Mejía Enrique
Published: April 2024

El objetivo de esta comunicación fue conocer los antecedentes históricos del ingenio como ha- bilidad del pensamiento y su presencia como contenido escolar en el ámbito educativo. La tesis central del estudio fue considerar que la emergencia de las habilidades individuales se da a partir de las competencias sociales interindividuales y que estos desempeños individuales, por tanto, surgen de la vida comunitaria. Para alcanzar este objetivo se realiza un análisis histórico de la habilidad del pensamiento de ingenio, revisando la obra de Quintiliano del siglo I de nuestra era, la propuesta visionaria de Huarte en el siglo XVI y, por último, las teorías de Gracián y de Vico de los siglos XVI y XVII. A continuación se presenta la incorporación del ingenio como contenido escolar en el siglo XX. Por último, se trazan los puntos de contacto entre las condiciones culturales y la enseñanza del ingenio.

La llegada de las Misiones Culturales a tierras chiapanecas fue un poco tardía. La organización de Institutos de Acción Social en los municipios de Huixtla, San Cristóbal de las Casas y Tuxtla Gutiérrez, entre julio y octubre de 1927, resultó ser un evento que reunió no solo a profesores federales y estatales de la localidad y sus alrededores, sino también a alumnos y pobladores. Inscrito en un estudio de educación rural, este artículo desarrolla, mediante el análisis de los informes de trabajo que los misioneros enviaban a la SEP y que podemos consultar en el Fondo de dicha Secretaría del AGN, los nombres de los especialistas, cómo fue su labor, qué actividades realizaron, con qué materiales, quiénes participaron y los retos que enfrentaron en Chiapas, un territorio de características particulares, como su importante población indígena, su difícil geografía, el poder de los finqueros y la carencia de recursos.

No Centenário de São Vicente: Sua Luta contra o Jansenismo
Authors: Silva Belchior Cornélio da
Published: April 2024

Empreendemos o estudo da luta empenhada por São Vicente de Paulo contra o Jansenismo movido pelo desejo de focalizar um dos traços mais característicos, embora pouco conhecido, de sua pessoa: a absoluta fidelidade à Santa Sé. É, aliás, a própria Igreja que enaltece êste título do grande Santo, ao invocá-lo na ladainha: Sancte Vincenti, Cathedrae Petri usque ad mortem coniunctissime, e ao proclamar que êle, “protegido sob o escudo da verdade, soube destruir os sutis artifícios das novidades" (Hino de Matinas, 19 de julho)...
Concepção Católica da Igreja

Published: April 2024

O século XVIII quase todo não iria trazer, vimos, novas orientações e idéias em eclesiologia, continuando, pura e simplesmente, na linha recebida do “após-Trento”.

O grande e original movimento que vai começar nas primeiras décadas do século XIX tem origens muito complexas. Pois não é um movimento eclesiológico apenas, mas uma tentativa de revisão metodológica em tôda a teologia. É um movimento de cuja inspiração fundamental podemos descobrir os frutos, não somente em religião e teologia, mas na filosofia, na moral e na arte...

Numa leitura, seja embora apressada, das obras publicadas pelas Testemunhas, impressiona-nos o número de pontos mesmo essenciais, em que as suas doutrinas divergem das nossas, e até das do “cristianismo” em geral. Não é exagêro afirmar, que esta seita é um verdadeiro sincretismo de heresias...
