Published: April 2021

On July 17, 2006 an earthquake with a magnitude of 7.7 triggered a tsunami that struck 500 km of the coast in the south of the island of Java. The tsunami generated is classified as an earthquake tsunami because the waves generated were quite large compared to the strength of the earthquake. The difference in the strength of the earthquake and the resulting tsunami requires a tsunami modeling study with an estimated fault area in addition to using aftershock and scaling law. The purpose of this study is to validate tsunamis that occur based on the estimation of the source mechanism and the area of earthquake faults. Determination of earthquake source mechanism parameters using the Teleseismic Body-Wave Inversion method that uses teleseismic waveforms with the distance recorded waveform from the source between Whereas, tsunami modeling is carried out using the Community Model Interface for Tsunami (commit) method. Fault plane parameters that obtained were strike , dip , and rake with dominant slip pointing up to north-north-west with a maximum value of 1.7 m. The fault plane is estimated to have a length of 280 km in the strike direction and a width of 102 km in the dip direction. From the results of the tsunami modeling, the maximum inundation area is 0.32 km2 in residential areas flanked by Pangandaran bays and the maximum run-up of 380.96 cm in Pasir Putih beach area. The tsunami modeling results in much smaller inundation and run-up from field observations, it was assumed that the fault plane segmentation had occurred due to the greater energy released than the one from the fault area, causing waves much larger than the modeling results.

Se realizó un estudio fitoquímico de metabolitos secundarios, actividad antimicrobiana y letal del extracto metanólico de las partes botánicas de Lippia citriodora K (cedrón). Se detectó la presencia taninos, polifenoles, triterpenos y esteroles insaturados para las hojas, flores y tallo; fenilpropanoides y catequinas para tallos y flores; alcaloides para hojas y flores; saponinas para hojas y tallos. Además, las flores exhibieron la presencia de cumarinas y metilencetonas. Todos los extractos metanólicos mostraron una acción bactericida alta contra cepas de Escherichia coli, Staphylococcus aureus y Pseudomonas aeruginosa, a excepción del extracto de las flores que exhibió una actividad antibacteriana moderada o mediana contra cepas de S. aureus. Además, se observó un efecto antifúngico moderado del extracto de las hojas, y una actividad alta de los extractos del tallo y flores, contra la cepa del hongo Candida albicans. Todos los extractos mostraron letalidad significativa (<1000 µg/ml) frente a nauplios de Artemia salina a las 24 h de exposición (168,77, 82,19 y 172,76 µg/ml para las hojas, tallo y flores, respectivamente); donde el extracto del tallo presentó mayor letalidad con CL50 de 82,19 µg/ml, considerado altamente tóxico según CYTED. Se puede inferir que la especie L. citriodora es una fuente promisoria de metabolitos secundarios bioactivos con actividad farmacológica.AbstractThis research was based on a phytochemical study of secondary metabolites, lethal and antimicrobial activity of methanolic extract of botanical organs Lippia citriodora K (lemon verbena). It was detected the presence of tannins, polyphenols, triterpenes and unsaturated sterols for leaves, flowers and stem; phenylpropanoids and catechins for stems and flowers; alkaloids for leaves and flowers; saponins for leaves and stems. In addition, the flowers exhibited the presence of coumarins and methylenketones. Methanolic extracts showed high bactericidal action against strains of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa, in the antimicrobial bioassay, except for the flowers which exhibited moderate activity against S. aureus strains. Furthermore, moderate antifungal effect was observed for leaves extract and high activity for stem and flowers extracts against the strain of Candida albicans fungus. All extracts showed significant lethality (<1000 μg/ml) against A. salina nauplii at 24 h of exposure (168.77, 82.19 and 172.76 μg/mL for leaves, stems and flowers, respectively); where the methanolic extract of the stem showed the highest lethality with LC50 value of 82.19 μg/ml, considered highly toxic according to CYTED. It can be inferred that L. citriodora is a promising source of bioactive secondary metabolites with pharmacological activity.

El desarrollo integral sucede en las personas a lo largo de la vida; potencia sus habilidades y destrezas como resultado de la incidencia que tienen factores ambientales, históricos, sociales y culturales. Entre los 0 y 6 años se conoce como desarrollo infantil integral. La educación inicial, por su parte, es el proceso de enseñanza-aprendizaje que sucede entre los 2 y 5 años de edad. En estas edades se fortalecen y potencian habilidades y destrezas cognitivas, motoras, psicosociales. Durante muchos años se ha pretendido distinguir al desarrollo infantil de la educación inicial, pero son dos procesos relacionados. En Ecuador, estos procesos están contemplados en la legislación nacional; sin embargo, no son considerados por parte del Estado, como de asistencia obligatoria y algunas familias no dimensionan su real importancia. Este artículo pretende mostrar la necesidad de fortalecer las políticas públicas para incrementar la cobertura y acceso a los servicios de educación inicial y desarrollo infantil para forjar la mejora de las condiciones de vida de niñas y niños entre los 0 y 5 años. Para ello se han organizado aspectos teóricos y estadísticos que denotan los avances que se han alcanzado en los últimos 12 años. Finalmente, se establecen una serie de breves conclusiones. AbstractIntegral development occurs in people throughout their lives; it enhances their skills and abilities as a result of the impact of environmental, historical, social and cultural factors. Between the ages of 0 and 6 it is known as integral child development. Initial education, on the other hand, is the teaching-learning process that takes place between 2 and 5 years of age. At these ages, cognitive, motor and psychosocial skills and abilities are strengthened and enhanced. For many years there has been an attempt to distinguish child development from initial education, but these are two related processes. In Ecuador, these processes are contemplated in national legislation; however, they are not considered by the State to be compulsory attendance and some families do not appreciate their real importance. This article aims to show the need to strengthen public policies to increase coverage and access to early education and child development services in order to improve the living conditions of girls and boys between 0 and 5 years of age. To this end, theoretical and statistical aspects have been organized to show the progress made in the last 12 years. Finally, a series of brief conclusions are established.

El presente artículo tienen como objetivo exponer los principales resultados obtenidos en el análisis de la relación entre educación emocional y aprendizaje del ámbito de la convivencia en los niños de 4 a 5 años del Centro de Educación Inicial “Mundo Mágico”. Los infantes de este centro educativo manifiestan actitudes negativas en su comportamiento, se pelean con sus compañeros de clase, mientras que otros no mantienen concentración con respecto a las actividades que desarrolla la docente, entre otras problemáticas que dieron paso para la ejecución del presente trabajo investigativo. La investigación se desarrolló con enfoque mixto, con la finalidad de describir las características de ambas variables, sus relaciones y posibles soluciones que puedan darse a las falencias evidenciadas en el centro referido. Los resultados confirmaron la existencia de insuficiencias en el ámbito de convivencia a partir de falencias en la educación emocional. Consecuentemente, se propone una guía de estrategias educativas, con actividades dirigidas a docentes a cargo del aprendizaje de los infantes, siendo estos los beneficiarios principales, ya que podrán mejorar sus actitudes con sus compañeros de clase y con ello, el ámbito de la convivencia. Igualmente, se considera que tanto padres de familia como institución en general serán beneficiados con dicha propuesta, mejorando la dirección del proceso de enseñanza-aprendizaje.

El agua subterránea es un recurso limitada con una alta vulnerabilidad a factores naturales o antropogénicos que pueden alterar sus atributos físicos, químicos y biológicos; y transformar este recurso en no apto para las actividades humanas incluido la agricultura. Aspecto que motivó la investigación, y tuvo como objetivo evaluar las aguas subterráneas de la parroquia La Peaña, en la provincia de El Oro (Ecuador). Para esto, se delimitaron 22 pozos ubicados en varias fincas bananeras, donde se tomaron muestras para determinar las propiedades color y olor; así como el pH, la conductividad eléctrica y la temperatura. También se delimito 10 submuestras a las que se realizaron análisis biológicos de coliformes totales, Escherichia coli y de los metales pesados: Hg. Pb. As. Cd y Mn. Los resultados mostraron un color transparente y sin olor en más del 80% de los pozos. El rango del pH 7.28-8.27 mostró una tendencia hacia la alcalinidad, con ligera presencia de salinidad por su baja CE (rango, 0.17-0.39 mS m). Las bacterias coliformes estuvieron en seis pozos con niveles sobre los 30 UFC ml-1). Los metales Hg, Pb, As y Cd obtuvieron medias de 0.29 ug l-1, 5 ugl-1; 10.00 ug l-1 y 0.80 ug l-1, respetivamente, mientras que el Mn mostró la mayor variabilidad con rango de 0.06-1240 ug l-1. Se recomienda no utilizar el agua con niveles altos de coliformes totales en el proceso de poscosecha del banano.

The base for this research work was set in the study of the interaction between legume flours and tuber starch blends to be used for sweet biscuits formulations and the successive evaluation of quality parameters. As main inputs the following were used: legume flours, manioc starch, margarine, sugar, eggs, and baking soda. Basic utensils: plastic and aluminum trays, biscuits shapers, cutters, other biscuit items. Analytical balance, mixer, and oven. Methods: Establishment of experimental units, analysis of manioc starch and legume flours, moisture analysis, ash content determination, rheological analysis of blends, gluten analysis in the blend of starch and legumes flours, dough formulation and biscuit making, textural a color analysis, sensory analysis of biscuits, statistical analysis. The results of moisture and ash analyzes in the inputs for blends were within the limits established of 14,5%. Ash content found was 2.3% in starch, 6.3% in soybean meal, and 2.9% in chickpea flour. Gluten content was around 10 mg/g in average in the 3 samples. Concerning rheological characterization, water absorption for the 3 blends was relatively low. Values resulted for the torque were within 1.1 Nm; time required to reach this value did not exceed two minutes of kneading stability. The 3 blends denoted low amylasic activity, as well as low starch damage. Gel stability results were due to the high amylasic activity occurred in manioc starch. The retrogradation intensity predicted that the 3 blends would have a long shelf life since retrogradation processes were low for the 3 cases. Hardness presented in samples was due to protein supply provided by soybean meal. According to the sensory analysis average results for texture, flavor, and color attribute, differences were found. The ANOVA for sensory evaluation in biscuits showed differences regarding texture, flavor, and color attributes in biscuits. The moisture values obtained for each biscuit sample were similar to each other and did not exceed 3%. Tuber starch and legume flour incorporation in formulation to produce gluten-free biscuits contributes to the development of a flavorsome product and provides an alternative for people with gluten intolerance. The results obtained may be used as the basis for the production of gluten-free biscuits.

O racismo institucional subalterniza e estigmatiza a população negra brasileira (negros e pardos). Ele é uma das modalidades que confirmam o Brasil como um dos países que mais violam os direitos humanos no mundo, segundo a Anistia Internacional em 2018. Nesse contexto, a pesquisa procura saber como ele se manifesta através de textos jornalísticos e televisivos, e se institui de maneira totalitária advindo das associações e órgãos institucionais. Por meio do método de "Análise de Conteúdo", aliado à teoria de Hall (2016), este estudo realizou uma análise de uma publicação do ano de 2019 pelo Jornal Extra buscando entender como ocorre a representação dos negros em matérias que circulam neste jornal popular. Os principais resultados ratificaram que esse veículo jornalístico se apropria de linguagens e imagens discursivas que banalizam o racismo institucional, legitimando uma estrutura racista, através de omissões e exercícios que levam em conta o fator racial dos negros do país.
