Abstract: In this work we review our new methods to computer generate amorphous atomic topologies of several binary alloys: SiH, SiN, CN; binary systems based on group IV elements like SiC; the GeSe 2 chalcogenide; aluminum-based systems: AlN and AlSi, and the CuZr amorphous alloy. We use an ab initio approach based on density functionals and computationally thermally-randomized periodically-continued cells with at least 108 atoms. The computational thermal process to generate the amorphous alloys is the undermelt-quench approach, or one of its variants, that consists in linearly heating the samples to just below their melting (or liquidus) temperatures, and then linearly cooling them afterwards. These processes are carried out from initial crystalline conditions using short and long time steps. We find that a step four-times the default time step is adequate for most of the simulations. Radial distribution functions (partial and total) are calculated and compared whenever possible with experimental results, and the agreement is very good. For some materials we report studies of the effect of the topological disorder on their electronic and vibrational densities of states and on their optical properties.
PRINCIPALES CAUSAS DE MUERTES Y CORRELACION CLINICO-PATOLOGICA EN UNA UNIDAD DE CUIDADOS INTENSIVOS The main basic causes of death and the clinical pathological correlation in an intensive care unit

Abstract: Se estudiaron 224 fallecidos con autopsias, en Unidad de Cuidados Intensivos del Hospital Dr. Carlos J. Finlay, en el período del 2000 al 2002, con el propósito de precisar las principales causas básicas y directas de muertes, así como determinar el grado de correlación clínico-patológica; con este fin, se utilizó la clasificación empleada en el Sistema Automatizado de Registro y Control de Anatomía Patológica. La ateroesclerosis coronaria constituyó la principal causa básica de muerte, tanto por diagnóstico clínico como autópsico y el choque fue la causa directa más frecuente. La discrepancia diagnóstica fue de 26.1%, en la causa básica de muerte, y de 29.9%, en la causa directa de muerte. In the intensive care unit at Carlos J. Finlay Hospital ,224 deceased with necropsy documents were studied from 2000 to 2002, in order to determine the main basic and direct causes of death and to know the clinical pathological correlation, with this purpose was utilized a classification applied in the automated system of registration and control of pathological anatomy. The coronary arteriosclerosis represents the main basic cause of death for clinical diagnosis for necropsies and shock is the most frequent direct cause. The diagnostic discrepancy is 26.1% in the basic cause of death and 29.9% in the direct cause of death.

Solar Driven Wind Speed Monitoring System Using Wireless or Wired Sensors  [PDF]
Federico Hahn, Mauricio Pablo, José Reyes
Energy and Power Engineering (EPE) , 2014, DOI: 10.4236/epe.2014.69019
Abstract: Instrumented towers are being constructed to characterize vertical wind profiles in order to improve the understanding and characterization of a desired environment up to 100 m. The site being measured is at a height of 2500 m over sea level, in one side of Sierra Madre Oriental, which crosses Mexico from North to South. As the site has no energy, it was powered by a photovoltaic system. Power consumption of two sets of sensors fixed at the tower was evaluated. The first sensor set consisted of a pulsed anemometer and a RH sensor having a 0 - 10 V output; these sensors used cables for transmitting the output signals. Three cup anemometers fixed at 25, 35 and 45 m high measured wind speed. Wireless sensors in the second set, requires of a power consumption and battery life study. Solar cells energized the sensors, becoming the installation and operation easier. The datalogger that acquired the RH and T measurements encountered an 11% voltage loss throughout the cable; cup anemometer measurements did not show variations due to its pulsed signals. Wireless sensors drew less energy from the PV system, resulting in battery overcharge. A dump regulator turned-on a 200 W lamp during the night when the battery voltage reached 14 V; the lamp was turned-off when the battery voltage felt beneath 11.5 V. Considering the high wind available, wireless sensors batteries were charged by small wind turbines combined with 5 W solar panels.
Flow Stagnation under Single and Two-Phase Natural Circulation Conditions in the APEX-CE Test Facility
José N. Reyes Jr.
Science and Technology of Nuclear Installations , 2008, DOI: 10.1155/2008/453621
Abstract: Natural circulation experiments were conducted at Oregon State University using the advanced plant experiment (APEX-CE) integral system test facility as configured to simulate a typical 2×4 Combustion Engineering nuclear steam supply system. This paper describes the mechanisms by which natural circulation flow was interrupted under single-phase and two-phase natural circulation conditions in APEX-CE.
SANTIDAD Y VIRTUDES ESENCIALES DE LA VIDA CRISTIANA. UNA LECTURA MARIANA
Reyes F,José Orlando;
Theologica Xaveriana , 2008,
Abstract: this paper researches concisely the biblical and theological meaning of holiness, expressed in faith, love and hope, which leads us to a marian reading meaningful for the present day believer. it also invites the reader to be in the society a person of faith, assuming it as a gift, aperture, response and fidelity to god; and with the example of mary opening up to the word and its dynamicity, which disposes the existence to the meeting with the others in the living experience of love; because love is the "permanent state of a christian" which activates the joyful expectancy of new human realities, impregnated by the saving action of god in history.

Abstract: El artículo indaga someramente por el sentido bíblico y teológico de la santidad, expresada en la fe, el amor y la esperanza, que nos conducen a una lectura mariana significativa para el creyente de hoy. También hace una invitación a ser en una sociedad personas de fe, asumiendo ésta como don, apertura, respuesta y fidelidad a Dios; y con el ejemplo de María, a abrirse a la Palabra y a su dinamismo, que dispone la existencia al encuentro con el otro en la vivencia del amor; porque el amor es el "estado permanente del cristiano" que activa la espera gozosa de nuevas realidades humanas, impregnadas por la acción de salvación de Dios en la historia. O artigo indaga simplesmente por o sentido bíblico e teológico da santidade, na express o da fé, o amor e a esperan a, que leva-nos a uma leitura mariana cheia de significa o para o fiel de hoje. Também faz uma incita o a ser uma sociedade de pessoas de fé, onde assume-se como dom, abertura o fidelidade a Deus; e com o exemplo de Maria na abertura da palavra e a seu dinamismo, que disp e a existência ao encontro com ou outro na vivencia do "porque o amor é o estado constante do crist o amor" que ativa a esperan a gozosa de novas realidades humanas cheias pela a o de salva o de Deus na história. This paper researches concisely the biblical and theological meaning of holiness, expressed in faith, love and hope, which leads us to a Marian reading meaningful for the present day believer.
