Inteligencia emocional para mejorar el pensamiento crítico
The objective of the research was to propose an emotional intelligence program to improve the critical thinking of second year high school science students of the Aida León de Rodríguez Lara Educational Unit, Guayaquil 2021. The research methodology was of applied type, with a quantitative approach; and non-experimental design of transactional scope, the sample was a census of 60 students, the technique employee for data collection was the survey and as an instrument a questionnaire was used for the two research variables, the instruments were validated according to expert judgment and then proceeded with the reliability test of Cronbach’s Alpha resulting for the independent variable a level of 0.092 and for the dependent variable 0.896 concluding that the instruments are truthful. The most significant conclusion is that students expose their thoughts as they conceive them without stopping to think about the consequences of their statements or those who may be harmed, causing problems in the interrelationship with the peers, they do not usually contribute with solutions to a problem due to lack of initiative. Finally, they do not know how to influence people to get out of any circumstance achieving things a favor.La investigación tuvo como objetivo plantear un programa de inteligencia emocional para mejorar el pensamiento crítico de los estudiantes de segundo año de bachillerato en ciencias de la Unidad Educativa Aida León Rodríguez Lara, Guayaquil 2021. La metodología de investigación fue de tipo aplicado, con un enfoque cuantitativo; y diseño no experimental de alcance transaccional, la muestra fue censal de 60 estudiantes, la técnica empleada para la recolección de datos fue la encuesta y como instrumento se utilizó un cuestionario para las dos variables de investigación, los instrumentos fueron validados según juicio de expertos y luego se procedió con la prueba de confiabilidad del Alfa Cronbach resultando para la variable independiente un nivel de 0,902 y para la variable dependiente 0,896 concluyéndose que los instrumentos son confiables. La conclusión más significativa es que los estudiantes exponen sus pensamientos tal cual los conciben sin detenerse a pensar acerca de las consecuencias de sus declaraciones ni a quienes pueden vulnerar originando problemas en la interrelación con sus compañeros, no suelen contribuir con soluciones frente a un problema debido a la falta de iniciativa, y, por último, no saben influir sobre las personas para lograr salir de cualquier circunstancia logrando cosas a favor
Stellar Coronal and Wind Models: Impact on Exoplanets
Surface magnetism is believed to be the main driver of coronal heating and
stellar wind acceleration. Coronae are believed to be formed by plasma confined
in closed magnetic coronal loops of the stars, with winds mainly originating in
open magnetic field line regions. In this Chapter, we review some basic
properties of stellar coronae and winds and present some existing models. In
the last part of this Chapter, we discuss the effects of coronal winds on
exoplanets.Comment: Chapter published in the "Handbook of Exoplanets", Editors in Chief:

A biochemical hypothesis on the formation of fingerprints using a turing patterns approach
<p>Abstract</p> <p>Background</p> <p>Fingerprints represent a particular characteristic for each individual. Characteristic patterns are also formed on the palms of the hands and soles of the feet. Their origin and development is still unknown but it is believed to have a strong genetic component, although it is not the only thing determining its formation. Each fingerprint is a papillary drawing composed by papillae and rete ridges (crests). This paper proposes a phenomenological model describing fingerprint pattern formation using reaction diffusion equations with Turing space parameters.</p> <p>Results</p> <p>Several numerical examples were solved regarding simplified finger geometries to study pattern formation. The finite element method was used for numerical solution, in conjunction with the Newton-Raphson method to approximate nonlinear partial differential equations.</p> <p>Conclusions</p> <p>The numerical examples showed that the model could represent the formation of different types of fingerprint characteristics in each individual.</p

Histopathological alterations in Senegal sole, Solea Senegalensis, from a polluted Huelva estuary (SW, Spain)
As a component of a large research project to evaluate the effects of contaminants on fish health in the field, histopathological studies have been conducted to help establish causal relationship between pollutants (heavy metals and aromatic polycyclic hydrocarbons—PAHs) and histopathological responses in Senegal sole, Solea senegalensis, from an estuary of SW Spain. Heavy metals (As, Zn, Cd, Pb, Cu and Fe) and 16 PAHs (proprietary USEPA) concentrations in water, sediment and tissues (liver and gills) and histopathological alterations in S. senegalensis from three sampling sites of Ria de Huelva estuary during 2004–2006 years have been analysed. The histopathological studies revealed seasonal and spatial differences in the lesion grade of alterations observing the highest lesion grades in fish from Odiel River and autumn season. No significant differences were observed in the alterations prevalence between sampling sites, but significant differences were observed between seasons observing the highest prevalence in autumn season. However, calculated IPAT demonstrated a low–moderate impact of pollutants on health fish. Correlations between histopathological alterations and pollutants analysed were observed being heavy metals the group that presented a major number of correlations with alterations in several organs of S. senegalensis. In evaluating the general health of fish, the use of histopathological studies in recommended for making more reliable assessment of biochemical responses in fish exposed to a variety of environmental stressors. Statistical analysis using semiquantitative data on pathological lesions can help to establish correlation between cause (stressor) and effect (biomarker)
