Authors: Abdulrahman Ahmed F. , Ahmed Sabah M. , Ahmed Naser M.
Published: January 2019

ZnO nanorods arrays are synthesized over the different substrates namely; Indium Tin Oxide (ITO), Kapton Tape (KT), Polyethylene terephthalate (PET), Porous Silicon (PS) and Silicon (Si) using modified chemical bath deposition (MCBD) method at 95 ºC for 4 h. The MCBD is the air bubbles inside growth solution during CBD process. The ZnO nano-seed layers are coated on different substrates using RF magnetron sputtering technique. The optical properties (transmittance, reflectance and energy band gap) and surface morphology of ZnO nanorods grown on different substrates have been investigated in details by using UV-Visible Spectrometer and Field emission scanning electron microscopy (FESEM), respectively. The results found that the morphology and diameter of ZnO nanorods is closely concerned to the nature of substrates. Also it is indicated that the substrate has strong and important impact on the growth, optical properties, Egand quality of synthesized ZnO nanorods (NRs). The higher transmittance has been observed for ZnO NRs grown over KT substrates and is about (~ 33 %). The average transmittance decreases sharply near UV region at wavelength around 393 nm for ZnO nanorods grown on ITO substrate. However, for PET and KT substrates, the transmittance decreases sharply near visible region around 401nm and 498 nm, respectively. Besides, the ZnO NRs grown on PS substrate have the strong reflectance characteristics after approximately 395 nm, and then decreases in the wavelength range of 410 nm to 700 nm. On the other hand, the strong reflectance property of ZnO NRs grown on Si substrate is observed at 400 nm.  Also the minimum and maximum Egare obtained for ZnO nanorods that fabricated on the KT substrate and porous silicon substrate, respectively.

Oligothiophene Synthesis by a Distinct, General C−H Activation Mechanism: Electrophilic Concerted Metalation-Deprotonation (eCMD)
Authors: Wang Long , Carrow Brad
Published: January 2019

Oxidative C–H/C–H coupling is a promising synthetic route for the streamlined construction of conjugated organic materials for optoelectronic applications. Broader adoption of these methods is nevertheless hindered by the need for catalysts that excel in forging core semiconductor motifs, such as ubiquitous oligothiophenes, with high efficiency in the absence of metal reagents. We report a (thioether)Pd-catalyzed oxidative coupling method for the rapid assembly of both privileged oligothiophenes and challenging hindered cases, even at low catalyst loading under Ag- and Cu-free conditions. A combined experimental and computational mechanistic study was undertaken to understand how a simple thioether ligand, MeS(CH2)3SO3Na, leads to such potent reactivity toward electron-rich substrates. The consensus from these data is that a concerted, base-assisted C–H cleavage transition state is operative, but thioether coordination to Pd is associated with decreased synchronicity (bond formation exceeding bond breaking) versus the classic concerted metalation-deprotonation (CMD) model. Enhanced positive charge build-up on the substrate results from this perturbation, which rationalizes experimental trends strongly favoring π-basic sites. The term electrophilic CMD (eCMD) is introduced to distinguish this mechanism. More O'Ferrall-Jencks analysis further suggests eCMD should be a general mechanism manifested by many metal complexes. A preliminary classification of complexes into those favoring eCMD or standard CMD is proposed, which should be informative for studies toward tunable catalyst-controlled reactivity.
Prevention and Early Detection of Congenital Heart Defects. Where do we stand.
Authors: Petropoulos Andreas
Published: January 2019

Introduction: Since the origin of Medicine in 4th BC. Century research has taught us that learning and practicing preventive medicine is properly the best method to prevent disease from happening in the first place. Preventive health care must be planned and executed ahead of time, even when illness/ disease, is absent, especially for those that are common and fаtal. Among neonates and infants, congenital heart disease (CHD) is responsible for the largest proportion of mortality caused by birth defects. Actual numbers of patients and mortality resulting from CHD reportedly is increasing. In the developed world the treatment of CHD has escalating costs for health care systems and private covered patients, while in low-income countries it is not always available. Prevention is urgently needed to tackle the increasing needs.

Aim: To present the current practice in preventing/early detecting CHD and justify why pulse oximetry is the best available, early detecting postnatal screening test we currently have.

Methods: The existing in use preventing/early detecting methods for avoiding or early diagnosing CHD are: 1. Eliminate the maternal risk factors by obtaining a good level of health and medical surveillance during pregnancy. 2. Avoiding teratogenic agents, 3. Detecting risk factors from Family History, 4. Delivering a balanced Nutrition during Pregnancy 5. Obtaining at least an experienced 4-chamber view and outflow tracts imaging during the 20-weeks anomaly scan. 6. Fetal Echocardiography when indicated 7. Postnatal evaluation by experienced Pediatricians. 8. Pulse Oximetry, screening test after 72 hours post-delivery in term babies. 9. Hyperoxia test when indicated.

Conclusion: Although CHD’s are the most common, high morbidity and mortality, congenital malformations, we still lack a single, easy to apply, non-invasive and low-cost screening test, for early detection. The current preventive methods must be combined to counterbalance the CHD prevalence. Meanwhile, they are costly and partially accessible. The most advantageous method for minimizing CHD deaths worldwide seems to be currently, pulse oximetry combined with clinical assessment.

Authors: Petropoulos Andreas
Published: January 2019

Introduction: Preventive medicine is the ideal way in dealing with frequent and fatal diseases. Congenital heart disease (CHD) is responsible for the largest proportion of mortality caused by birth defects in the first year of life. Actual numbers and mortality from CHD is increasing. In the developed world the treatment of CHD has escalating costs for health care systems and private covered patients, while in low-income countries the resources are minimal. Prevention/early detection is urgently needed to tackle the increasing needs.

Aim: To justify why pulse oximetry (pox) is the best available, early detecting postnatal screening test currently.

Conclusion: Although CHD’s are both frequent and carry a high morbidity and mortality, we still lack a single, easy to apply, non-invasive and low-cost screening test, worldwide. The most advantageous method for minimizing CHD deaths worldwide seems to be currently, the combination of clinical assessment with pox.

Published: January 2019

En Baja California Sur (BCS) el escenario del turismo, se matiza por empresas de capital extranjero, situación que se agudiza en sus principales destinos: La Paz, Los Cabos y Loreto. Sumado a ello, la coyuntura nacional se ha permeado en el contexto local, contribuyendo a elevar el desempleo y la inseguridad. Lo anterior, representa un escenario adverso que puede limitar el desarrollo de nuevos emprendedores especialmente, de los millenial que recién egresan de las universidades. Para dimensionar la problemática anterior, es necesario contar con información sobre experiencias de los jóvenes que recién han incursionado como empresarios. El objetivo de este trabajo fue tomar como referencia cuatro casos de estudio para documentar las características de los negocios emprendidos por jóvenes egresados de la Licenciatura en Turismo Alternativo del campus La Paz, BCS. Las técnicas empleadas fueron: estudios de caso, encuestas y entrevistas. Los resultados indican que, los emprendedores perciben con seriedad las limitantes de obtener un financiamiento, esto se representa como limitante para mejorar el posicionamiento de sus empresas, no están dedicados exclusivamente a su empresa, lo que ocasiona desajustes económicos, de atención y de desarrollo de sus metas en distintos horizontes temporales además, si bien son personas con preparación académica, consideran que no poseen suficiente formación en áreas de gestión empresarial, condición que no les permite desarrollarse adecuadamente. Algunas reomendaciones son reforzar las acciones de emprendurismo desde edades tempranas y fortalecer la cultura empresarial en todos los niveles educativos particularmente en carerras vinculadas al turismo alternativo y de naturaleza.

El término de innovación ha adquirido muchas definiciones, originándose de su raíz etimológica, la cual proviene del latín innovare que significa cambiar; todas ellas coinciden precisamente en el cambio, en algo diferente, en algo nuevo o mejorado. Aquí lo relevante o el punto clave está en preguntarse qué es lo que se desea cambiar o mejorar. Formichella hace un análisis de este concepto de diferentes autores y enfatiza que dicho cambio puede realizarse en diversos aspectos, y representa a la innovación como una vía por la cual se conduce el conocimiento y se convierte en un proceso, producto o servicio que finalmente, se transforma para beneficio del mercado o para la sociedad 3. Aunado a este concepto, se puede definir a la Innovación Educativa como el uso creativo de los recursos humanos y materiales para propiciar un cambio que mejore la calidad del proceso de enseñanza-aprendizaje, a través de la colaboración de todos los implicados, que permitan la transformación o mejora de la educación 4. Asimismo, la Tecnología Educativa se podría definir como el uso de las Tecnologías de la Información y la Comunicación para fines educativos, así como la manera sistematizada de obtener, aplicar y evaluar todo lo que conlleva el proceso de enseñanza-aprendizaje mediante recursos humanos y tecnológicos involucrados, para lograr una educación de calidad 2.

La modelación matemática es una herramienta de gran utilidad para entender, de manera sencilla, algún problema de la realidad que sea de nuestro interés. En el caso de la transmisión de enfermedades, la epidemiología matemática ha servido para entender la mecánica de propagación entre la población. Los modelos deterministas como el SI, SIS, SIR, SEIR, han sido ampliamente estudiados, y son la base de modelos más complejos, en donde se incluye, por ejemplo, alguna política de vacunación.Otra alternativa es la modelación estocástica. En este trabajo presentamos dos modelos estocásticos, basados en cadenas de Markov. Ambos modelos son la versión estocástica del clásico SIS. El primero es un modelo de tiempo discreto, mientras que el segundo es un modelo de tiempo continuo. De cada uno de ellos presentamos simulaciones, y se sobreponen con la simulación realizada para el modelo determinista.
Inventario y Catalogación de Jardines Históricos, como Paisajes Culturales en la Ciudad de México, para su Reconocimiento en las Leyes de Bienes Culturales
Authors: Sandoval Morán Luisa
Published: January 2019

La tendencia del ser humano de transformar el medio ya sea rural o urbano en el que habita es parte de su naturaleza y los jardines, parques y plazas de carácter histórico en la Ciudad de México (CDMX), como parte de la creación humana se ven sujetos a dichos cambios, por lo que la presente investigación pretende colocar a los jardines históricos de la CDMX, como protagonistas dignos de ser conservados, pero además posicionarlos como sitios de gran utilidad, los cuales puedan otorgar a la población que los visita un conjunto de saberes que perduren de generación en generación y no se diluyan con el paso del tiempo. Dado que los jardines históricos de la CDMX combinan características arquitectónicas singulares y biológicas que en conjunto, brindan servicios ambientales y culturales de primordial importancia para la sociedad, derivados de una tradición prehispánica, pero que contradictoriamente no cuentan con una tutela óptima para su salvaguarda, en la Ley General de Monumentos en su última modificación del 2015, una alternativa legal local que contiene elementos favorables para tutelar a los Jardines Históricos como parte de Paisajes Culturales, es la Ley de Salvaguarda del Patrimonio Urbanístico Arquitectónico de la CDMX. En este tenor un inventario constituye una herramienta útil, para de esta forma poder realizar el catálogo que ayude a establecer las normas y procedimientos para su adecuada gestión y posicionarlos dentro de las leyes mexicanas, con el fin de coadyuvar a solventar las tendencias destructivas antrópicas al considerar nuevas rutas en su gestión.

Published: January 2019

El presente trabajo es un fragmento de la investigación de las técnicas constructivas en la fábrica de acueductos de influencia europea, de cómo fueron concebidos por la mezcla entre la cultura indígena y la cultura europea así como los aportes de cada una de ellas en los sistemas hidráulicos edificados en el siglo XVI durante el virreinato en el actual estado de Hidalgo, del cual se obtuvo como resultado parte de la evangelización local, desarrollo urbano regional, desarrollo económico y producción agrícola en las haciendas. Enfocado el actual fragmento en los riesgos detectados en los sitios donde se encuentran los acueductos, resaltan el fenómeno de la destrucción progresiva por parte de los pobladores aledaños así como el abandono de las autoridades y el desconocimiento acerca de una correcta actuación sobre los monumentos siendo todo empeorado por la meteorización de elementos expuestos por su ubicación así como algunos fenómenos naturales que ponen en riesgo la integridad de los acueductos. En conclusión, la forma óptima de conservación es la empatía con los monumentos, comprensión de su importancia por parte de los pobladores y un registro periódico de su estado físico
La Capilla de San Nicolás Tolentino de la Ciudad de Taxco de Alarcón, Guerrero e Implicaciones de la Cosmovisión Prehispánica en su Emplazamiento
Authors: Rodríguez Rodríguez Darío
Published: January 2019

Este trabajo consiste en una investigación histórica y arquitectónica de la iglesia de San Nicolás Tolentino de la ciudad de Taxco de Alarcón estado de Guerrero, cuyo objetivo fue descubrir el contenido histórico y simbólico de tan singular monumento. Es una de tantas iglesias edificadas por los primeros evangelizadores de la región: los frailes mendicantes de la orden de San Francisco, llegados a Cuernavaca en 1525. Mismos que siguiendo las reglas de pobreza observadas por casi trescientos años, la fabricaron de una sola nave, con muros de mampostería de piedra asentada con lodo, a la manera prehispánica y con la techumbre de palma a dos aguas. Y a pesar de su marcada sencillez, bien se asemeja a un verdadero “palimpsesto”, donde se puede leer claramente, entre otras cosas, tres adaptaciones que a través de su historia se llevaron a efecto: la primera, cuya fábrica estuvo a cargo de los padres franciscanos en el siglo XVI, la segunda correspondiente al siglo XVIII, y la tercera a la segunda mitad del siglo XIX. En otro sentido, se puede decir que, la disposición geométrica de la planta arquitectónica del conjunto, obedeció a los cánones de proporcionalidad y simbolismo de las primeras iglesias de la cristiandad. No así su emplazamiento y orientación, pues esas características no parecen corresponder a las tradiciones propias europeas, sino más bien, a un contexto típico del “Paisaje Ritual Prehispánico”. Por lo tanto, es deseable, que el conocimiento de los atributos de la iglesia de San Nicolás Tolentino traídos a la luz, ayuden a la justificación de su permanencia en un entorno urbano cada día más cambiante.

The purpose of this study is to examine aspects of prayer spirituality in the perspective of neuroscience and its implications for achievement. To see the relationship between the attitude of spirituality that is usually associated with prayer and endeavor, including business with the results obtained when done doing so. There is no connection between the brain and the activities of the owner of the brain because it is in the head and human activities are usually carried out in the outside area, but if you have studied the brain, especially neuroscience learning, then the body parts and what the owner does are interconnected. The results of the analysis mostly suggest that spirituality and learning achievement have relationships. The results of the study show that spirituality can be a predictor in one's learning achievement.

Fatwa is a very urgent case for humans because not everyone is able to explore the laws of the Shari'a. Or it can be concluded that the fatwa is an explanation of Sharia law on various issues that occur in the midst of society.

Therefore, given the importance of the position of the fatwa, it should be done that the people do not ignore the fatwas issued by the Fatwa scholars born because of the consideration of the benefit of the ummah or mashalihul ummah, and in this paper will be discussed about the methods of law enforcement in berfatwa.

Within the scope of the fatwa there are some important things that must be noticed by a mufti (giver of fatwas) and a mustafti (the person who asks fatwas) so that the resulting fatwa can be useful in solving a problematika. For the sake of perfection a fatwa of mustafti must use some method which must be consumed in solving problem which in ijtihadi at that time, like method bayani, ta'lili and termi.
