Comparación de los riesgos ambientales entre las técnicas del efecto inducido y el efecto espontáneo, utilizados en la microsísmica de baja frecuencia para explorar petróleo
Authors: Palacios Cabrera Teresa Alejandra , Nogales Flavio Rodrigo
Published: September 2019

La presente investigación se centró en el valor porcentual que afecta a la mesofauna edáfica, una vez aplicadas las técnicas del efecto Inducido y Espontáneo de la microsísmica, en la exploración de petróleo en la Amazonia. Para el análisis de la mesofauna edáfica se utilizó como bioindicadores las variedades: Arácnidos, Ciempiés (Artrópodos) y lombrices (Anélida); para el efecto, se establecieron tres áreas de estudio; uno en cada punto de aplicación de las técnicas del efecto Inducido y efecto Espontáneo de la microsísmica y un tercero, realizado en un punto equidistante de los dos anteriores como medida de control comparativa del estado y conservación de la mesofauna edáfica en el sector. En cada área de estudio se utilizó la metodología de “Muestreo en Cruz” que consiste en el trazado de 2 transectos en forma de cruz (+) de 51 m cada uno, donde se establecieron 10 sitios de muestreo de 1 m² cada uno, separados a 5 m de distancia, de donde se extrajeron 5 bloques de suelo de 20x20x20 cm, dando un total de 20 puntos de muestreo por área estudiada, lo que dio un total de 100 bloques cuantificados. Para el caso de las áreas de aplicación de la microsísmica, el punto de intersección de los transectos se ubicó en el centro de ejecución de las actividades. Al comparar porcentualmente entre las dos técnicas de la microsísmica la afectación a la mesofauna edáfica, respecto a la reducción de especímenes, se determinó que en el área de la técnica del Efecto Espontáneo se redujo un 39%. Mientras que en el área de la técnica del Efecto Inducido, la mesofauna edáfica se redujo un 61%; siendo la técnica del Efecto Inducido causante de mayor afectación en un 22%.

Published: September 2019

El estudio ha permitido establecer los indicadores y verificar el impacto en el suelo del páramo alto-andino de la Reserva Ecológica “El Ángel”, comprobándolo a través de la exploración de los humedales partiendo de análisis de laboratorio, que son los componentes que proveen los recursos hídricos necesarios para el consumo y el riego, manteniendo el equilibrio de la cuenca hidrográfica y su capacidad de fijación de carbono, lo que se relaciona íntimamente con: la escasa actividad de óxido-reducción, el ambiente con la humedad y el permanente volumen de recursos hídricos. Es importante que el Comité de Gestión de la reserva propicie la aplicación de la normativa legal y se implemente los instrumentos técnicos y tecnológicos que permitan subsanar la pérdida de la capacidad bioreguladora hídrica del páramo.

Published: September 2019

Yachay es una institución de educación superior y parque tecnológico, en el cual se generarán proyectos de energía solar a través de paneles fotovoltaicos. Este proceso puede generar la contaminación por plomo en los suelos, esto es posible en vista de que la mayoría de baterías que almacenan la energía solar son fabricadas con éste metal. La caracterización físico-química del suelo permite obtener información de sus propiedades. El objetivo de este trabajo fue caracterizar los suelos con parámetros como el pH, humedad, conductividad eléctrica, densidad real y aparente, porosidad y materia orgánica; también se planteó relacionar la biodisponibilidad y toxicidad del plomo para generar bases para futuros planes de control y contaminación de suelos agrícolas de la zona. Se utilizó el método de zig-zag seleccionando 10 puntos de muestreo georeferenciados en coordinación con la dirección de Gestión Ambiental de Yachay. Para la representación de estos datos se utilizó la interpolación IDW. El pH resultó de 8.14 promedio, el contenido de humedad estuvo asociado a un suelo franco-arenoso, la conductividad eléctrica fue 0,72 dS m-1, la materia orgánica indicó suelos aptos para la agricultura. Se diseñó un experimento de contaminación por Plomo en el suelo y se realizaron isotermas de adsorción. Así, los suelos de Yachay presentaron una textura franco-arenosa, los procesos de lixiviación y retención de plomo fueron bajos, un 15% de retención de plomo indicó que el plomo no se fija en los suelos de Yachay.
Resultados de nivelación de admisión, Caso FIGEMPA
Authors: Ortiz Herrera Jorge Daniel
Published: September 2019

El ingreso a una Universidad Pública en Ecuador se ha convertido en un desafío, principalmente porque hay nuevas disposiciones legales que han modificado la conducta de los bachilleres, tanto como por la no participación de las mismas Instituciones de Educación Superior. Se pretende hacer una revisión histórica del pasado inmediato en la Facultad de Ingeniería en Geología, Minas, Petróleos y Ambiental de la Universidad Central, como describir el actual tránsito del bachillerato a la educación superior y una presentación crítica de resultados obtenidos en nivelación de carreras del período 2015-2016. Ante el aviso por parte de la Secretaría Nacional de Educación Superior, Ciencia, Tecnología e Innovación, de que a futuro, se pretende que las dos Instituciones sean corresponsables de la admisión y nivelación, es de alta importancia: dimensionar la responsabilidad que se adquirirá y con ello se prevean las medidas a tomar. Una revisión de resultados anteriores, el tener claro y en detalle el perfil de bachiller que ofrecen los Colegios a la Sociedad, así como definir que conocimientos y habilidades requieren éstas carreras, permitirá que se ajuste el curso de nivelación para garantizar mejores niveles de promoción en primer semestre de las carreras mencionadas. Se quiere ratificar que el curso de nivelación debe tener una dedicación muy alta a las asignaturas de ciencias básicas, éstas son: matemática, física y química; base fundamental para las ingenierías; se pretende que, al menos un 90% de la carga horaria del curso se ocupe de las asignaturas descritas, y complementar con otras actividades necesarias para la comprensión y adaptación a la vida universitaria y que motiven la vocación de los bachilleres sea para ratificar su elección o para que, a tiempo se pueda revisar la decisión.

Published: September 2019

Después de explotar un campo petrolífero con recuperación primaria, se llega a extraer un promedio del 24% del petróleo existente en el yacimiento (SHE, 2013), posteriormente se pueden ejecutar procesos de recuperación secundaria aplicando métodos como inyección de agua o inyección de gas, recobrando aproximadamente el 40% del petróleo original existente en los yacimientos (Escobar 2014). El petróleo residual no es recuperado por procesos primarios o secundarios, debido a factores que limitan el uso de estos procesos de recuperación, como son: la pérdida de presión, pérdida de energía del yacimiento y la existencia de fuerzas capilares y viscosas en el yacimiento que se oponen a la movilidad del hidrocarburo. Para recuperar dicho petróleo residual, se utilizan procesos de recuperación mejorada (Enhanced Oil Recovery EOR), tales como de inyección de surfactantes, que disminuyen las fuerzas capilares que existen en el contacto agua-petróleo y a nivel de los poros de la roca, permitiendo disminuir la tensión interfacial contacto agua-petróleo, aumentando la movilidad del petróleo residual para su recuperación. Los proyectos de recuperación mejorada de petróleo en el Ecuador no se realizan por las altas inversiones que se requiere, pero otros países utilizan la inyección de surfactantes, por sus bajos costos, permitiendo el aumento en recuperación de petróleo de 3% a 5% en los yacimientos (COMERCIO 2016). Al analizar la influencia de la tensión superficial e interfacial de los surfactantes catiónicos en la emulsión agua petróleo, en base a criterios de la concentración micelar crítica cmc y análisis de la molécula por medio de espectroscopia infrarroja, dieron el mejor resultado.
Estimación empírica de la resistencia a compresión simple a partir del ensayo de carga puntual en rocas anisótropas (esquistos y pizarras)
Authors: Burbano Danny , García Tania
Published: September 2019

En este trabajo se establecen nuevas correlaciones empíricas entre la resistencia a compresión simple (RCS) y el índice de carga puntual Is(50) en rocas anisótropas, en particular en esquistos y pizarras. Se han empleado datos de 2.015 ensayos de carga puntual y 229 ensayos de resistencia a compresión uniaxial realizados en rocas anisótropas obtenidos en las diferentes etapas de estudio del proyecto hidroeléctrico Paute-Cardenillo, localizado en las estribaciones orientales de la cordillera de los Andes septentrionales (SE Ecuador). Se han identificado cinco litotipos de rocas anisótropas (esquistos y pizarras) para los que se han obtenido los valores medios de resistencia a compresión simple y del índice de carga puntual en función de su orientación con respecto a los planos de anisotropía. Finalmente, se comprueba que no existe una relación directa entre RCS y Is (50) por lo que no es fiable adoptar los modelos empíricos tradicionales de regresión lineal, que no tienen en cuenta el efecto de los planos de anisotropía en la resistencia de la roca. Por lo tanto, se proponen tres nuevas relaciones empíricas que permiten estimar la RCS a partir del Is (50) en rocas anisótropas.

Published: September 2019

La extracción del zinc que contienen las cenizas de galvanizado en caliente, se realizó usando ácido clorhídrico. La composición de las cenizas fue determinada por difracción de rayos x, obteniéndose zinc metálico, oxido y el hidróxido, siendo el mayor componente el óxido (49%). Las cenizas son sólidos granulares de forma irregular, las partículas con un diámetro promedio mayor dio las mayores tasas de velocidad. Las representaciones gráficas del modelo del núcleo que se encoje sin reaccionar controlado por la reacción química dieron una buena linealidad. Así mismo, se demostró que la velocidad de lixiviación no depende de la agitación, y la energía de activación estimada dio un valor de 18,4 kj/mol. La velocidad de la reacción puede ser determinada mediante la siguiente ecuación semiempírica.

Análisis de vulnerabilidad a la contaminación en los acuíferos de la unidad hidrogeológica Huaquillas
Authors: Alulema Del Salto Rafael Alberto , López Vera Stephanya
Published: September 2019

El análisis de vulnerabilidad de contaminación en un acuífero es una estimación del grado de exposición del manto de agua subterránea frente a un potencial contaminante (independientemente de su naturaleza o composición), en función de las propiedades intrínsecas del subsuelo. La vulnerabilidad de contaminación en la Unidad Hidrogeológica Huaquillas fue evaluada mediante dos métodos cualitativos: GOD y DRASTIC. Los mapas de vulnerabilidad generados han permitido catalogar a la llanura costera como la zona menos apta para tolerar una potencial dispersión contaminante. De acuerdo a los resultados obtenidos en el método DRASTIC, el acuífero Q2 y las zonas de los acuíferos Q1 y Ng que se ubican en la cuenca baja, presentan vulnerabilidad de contaminación media, mientras que, el método GOD cataloga a estas zonas con alto grado de vulnerabilidad. En la cuenca alta, la vulnerabilidad de los acuíferos Q1 y Ng varía entre baja a muy baja. Por lo tanto, los resultados de vulnerabilidad a la contaminación sugieren que la cuenca alta es la zona con menor grado de exposición ante un posible evento de contaminación, donde se podrían desarrollar actividades antrópicas sin poner en riesgo la calidad del recurso hídrico subterráneo.

Nesnellik, sosyal teoride, bilgi sosyolojisinde ve bilim felsefesinde en çok tartışılan konuların başında gelmektedir. Nesnellik, yaygın kullanımında, bilimsel faaliyetle eş değer tutularak incelenirken, bu yöndeki kullanımını olanaklı
kılan tarihsel temeller çoğunlukla hariçte tutulur. Nesnelliğin “bilen”in kanaatlerinden yalıtık olmayı, önyargı ve peşin hükümlerden sıyrılmayı öne çıkaran “tarafsızlığı” ve değer yargısız “nötr dil” söylemi genelde belli bir
nesnellik idealinin tarihsel inşası ile ilgilidir. Bunun yanında, nesnelliğin daha çok tartışmalı bir yer edindiği “perspektivizm” içinde, farklı bir okumaya tabi tutulduğunu da görüyoruz. Bu kapsamda makalenin amacı, temelde nesnelliğin
bu farklı kullanımlarına ilişkin, bir ideal olarak onun yükselişi ve düşüşüne dair, tarihsel bir tartışma sunmaktır.

Tarih öğretiminde yapılan çalışmalar; bilginin taşıdığı değerin ve öğrenci deneyimlerinin dikkate alınmasını, öğrencilerin yaşama etkin katılımlarını, doğru karar vermelerini, sorun çözmelerini destekleyici ve geliştirici, tasarlanan
sınıf içi ve sınıf dışı faaliyetlerde öğrencilerde yaratıcı, eleştirel, empatik düşünme becerilerinin ve kanıt temelli öğrenmenin ön plana çıktığı bir yaklaşımla hareket etmektedir. Bu yaklaşımla birlikte tarih dersinde her öğrenciye
ulaşabilmek için öğrenme-öğretme yöntem ve tekniklerinde tarih dersine özgü çeşitliliğin olması gerekmektedir. Bu nedenle tarih derslerinde uygulanabilecek aktif öğretim yöntemlerinin çeşitlendirilmesi ve zenginleştirilmesi önem
arz etmektedir. Bu çalışmanın amacı tarih derslerinde alternatif uygulama örneği olarak nitelendirilebilecek olan tarihsel canlandırma ve simülasyon uygulamalarını karşılaştırmalı olarak ele almak, benzerlik ve farklılıklarını
ortaya koymaktır. Söz konusu çalışmada simülasyon; bilgisayar ve teknoloji kullanımından çok bir konu üzerinde öğretmen tarafından derlenen kaynaklar aracılığıyla öğrencilerin sınıf içinde aktif bir şekilde yer almalarına olanak
sunan bir uygulama olarak ele alınmaktadır. Tarihsel canlandırma ise; tarihi gerçeklik çerçevesinde canlandırılan dönemin tarihi atmosferini oluşturarak, öğrencilerin gerçekleştirilecek önemli bir tarihi olaya tanıklık etmelerini
ve bu deneyimi yaşamalarına olanak tanıyan bir uygulama alanı olarak tanımlanmaktadır. Nitel araştırma deseninde tasarlanan bu araştırmada doküman analizi kullanılmış; söz konusu uygulama alanlarına ilişkin alan yazın incelenmiştir.
Sonuç olarak tarihsel canlandırma ve simülasyon; uygulama öncesi hazırlık, uygulama sırası ve uygulama sonrası değerlendirilme süreçleri açısından benzer noktaları olmasına rağmen simülasyonun tarihi mekân gerektirmemesi, yapay
bir problem durumunun oluşturulması gibi temel noktalarda tarihsel canlandırma uygulamalarından ayrılmaktadır. Eğitim ortamında iyi tasarlanan ve yönlendirilen simülasyon, öğrencilerin belirli kavram ve bilgileri öğrenmesini, karar
verme, problem çözme ve örüntü tanıma gibi birçok bilişsel becerinin gelişmesini kolaylaştırabilmektedir. Oysa tarihsel canlandırma uygulamaları süreçte bu bilişsel becerilerin yanında duyuşsal ve psikomotor becerilerin gelişimini
de önemsemektedir.

Published: September 2019

Six potential peptidomimetics of the cross-reactive neutralizing anti-HIV-1 antibody N6 that are able to mimic the pharmacophoric features of this immunoglobulin by specific and eﬀective interactions with the CD4-binding site of the viral gp120 protein were identified by virtual screening and molecular modeling. The key role in the interaction of these compounds with gp120 is shown to play multiple van der Waals contacts with conserved residues of the gp120 Phe43 cavity critical for the HIV binding to cellular receptor CD4, as well as hydrogen bonds with Asp-368gp120 that increase the chemical affinity without activating unwanted allosteric eﬀect. According to the data of molecular dynamics, the complexes of the identified ligands with gp120 are energetically stable and show the lower values of binding free energy compared with the HIV-1 inhibitors NBD-11021 and DMJ-II-121 used in the calculations as a positive control. The identified compounds may be involved in the design of novel antiviral drugs presenting HIV-1 inhibitors that block the early stages of the development of HIV infection.

Рrospects of research development and new applications of concentrated artificial latexes
Authors: Koshevar V. D. , Shkadretsova V. G. , Busel D. A. , Kazhuro I. P.
Published: September 2019

The phenomenon of strong stabilization of concentrated aqueous dispersions (emulsions) of polymers by colloidal particles of organic nature (microparticles of synthetic latexes), not accompanied by a significant increase in effective viscosity, opened, firstly, the possibility of carrying out the processes of pigmenting them at low energy costs with a maximum yield (dynamic state, meets the conditions of intensification of heterogeneous chemical-technological processes) and, secondly, determined the directions of further research in this area. So, in contrast to the classical method of emulsion stabilization by mineral microparticles adsorbed directly on the surface of their droplets, microparticles of organic origin interact with them through an interlayer of the dispersion medium, localizing in the immediate vicinity of the dispersed phase and thus maintaining a high mobility of the interphase boundaries. In this regard, the proposed method for predicting the type of emulsions of polymers, taking into account the contact wetting angle and the wetting area of the surface of solid particles of a stabilizer with water and a polymer, requires further verification on various systems. The obtained data of fundamental importance also allowed us to propose new applications of stabilized concentrated artificial latexes for solving applied problems.

Published: September 2019

Mechanisms of development of ischemic stroke are complex and have not been fully established. The aim of this study was to estimate the changes in the pool of free amino acids and biogenic animes in the brain cortex of rats with subtotal cerebral ischemia (SCI) and treated with L-NAME. Experiment was made on 18 rats: 12 animals were undergoing bilateral filament occlusion of arteries carotid, 6 of them were treated with L-NAME. The analyses of free amino acids levels in the blood plasma extracts were carried out by reversed phase HPLC.

Concentrations of several amino acids were elevated during SCI including aspartate, b-alanine, valine and leucine. In contrast, the levels of glutamate, asparagine, treonine, gamma-aminobutiric acid, tyrosine and 5-hydroxiindolylacetate were decreased. The administration of L-NAME partially prevented the imbalance of the amino acids pool due to SCI by normalizing the levels of aspartate, glutamate, asparagine, methionine, gamma-aminobutiric acid, b-alanine, 5-hydroxiindolylacetate. However, the administration of L-NAME has induced an additional imbalance in the amino acids pool in the brain cortex (decrease in the levels of glutamine, histidine, taurine, tryptophan, phenylalanine, tyrosine (in comparison to SCI) and decrease in the levels of treonine and arginine. The imbalance of the amino acids pool induced by the administration of L-NAME during SCI is more severe than the imbalance caused by SCI.

Published: September 2019

The aim of the study was to establish the diagnostic significance of biochemical parameters, considered as markers of epileptic seizures in patients with arterial aneurysms (AA). 82 patients with AA (50.4 ± 11.5 year-old) with epileptic seizures (35 persons) and without them (47 persons) were examined. Before treatment, the following biochemical parameters were determined in plasma of patients: lactate, pyruvate, products reacting with thiobarbituric acid (TBA-P), antioxidant activity of the serum, activity of superoxidedismutase and catalase, tumor necrosis factor-alpha (TNF-ά). To characterize the diagnostic significance of the results, the diagnostic sensitivity and the diagnostic efficacy were determined. The complex of biochemical tests with high diagnostic significance, consisting of lactate, lactate/pyruvateindex, catalase activity, TBA-P and TNF-α, was established in patients with AA with epileptic seizures. It allows considering these parameters as markers of epileptic seizures development in patients with AA. Among the most diagnostically significant tests for detection of epileptic seizures in patients with AA should be considered the concentration of TNF-ά with diagnostic sensitivity of 73%, the diagnostic specificity of 79% and the diagnostic efficacy of 75%.

The use of intraoperative neuromonitoring supervised the stem functions at all stages of tumor removal and during the vertebral artery allocation.
