Ante la crisis sanitaria provocada por la pandemia del COVID-19, las plataformas de telemedicina se han convertido en soluciones emergentes para la atención médica a distancia. Es cierto que se debe brindar atención presencial a los afectados por esta enfermedad; sin embargo, el resto de las enfermedades demandan una igual atención que en muchas ocasiones no es posible establecer una valoración in-situ. En este proyecto se diseña y desarrolla una web app de telemedicina con el uso de herramientas libres, que permita dar soporte al departamento médico de la Universidad Técnica Estatal de Quevedo (UTEQ) para brindar servicio médico de una manera accesible y sin exponer a las personas ante posibles contagios. Para los requerimientos, pruebas y ajustes del sistema, se contó con la colaboración de expertos en el área de la salud, considerando características específicas como diseño novedoso y uso intuitivo, otorgando al usuario diversas opciones tales como: la reserva de citas, un asistente virtual y acceso a consultas en tiempo real a través de aplicaciones telemáticas. Por último, se realizó un estudio de aceptabilidad y usabilidad con el fin de obtener una retroalimentación en cuanto al impacto y mejoras a desarrollar.

La investigación tuvo por objetivo diseñar un sistema computacional Web-App para el registro de datos in situ y para la estimación del almacenamiento de carbono aéreo en parcelas de café en Huatusco, Veracruz, México. Lo anterior se planteó por las necesidades de los productores para automatizar los cálculos de captura de CO2 que sirven en la contribución de la mitigación del cambio climático. El software se elaboró en el Campus Montecillo del Colegio de Postgraduados de febrero a octubre de 2020 a través de la propuesta de la metodología PADPEEM y probado con los datos obtenidos en algunos cultivos de café en Huatusco en enero de 2020. En los resultados se mostró el sistema CarbonoCafé, su arquitectura, mapa de navegación e interfaces. El sistema CarbonoCafé será de impacto en la reducción de recursos humanos, económicos y de tiempo, para el cálculo de carbono aéreo in situ. Además, contiene bases de datos que se pueden consultar desde cualquier computadora o teléfono móvil.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.

The Use of Advanced Analytical Techniques for Characterization of the Chemical, Physical, and Crystallographic Nature of a Surface

Scanning Electron

Studies of the nature of a surface, either metallic or nonmetallic, in the past, have been limited to the instrumentation available for these measurements. In the past, optical microscopy, replica transmission electron microscopy, electron or X-ray diffraction and optical or X-ray spectroscopy have provided the means of surface characterization. Actually, some of these techniques are not purely surface; the depth of penetration may be a few thousands of an inch. Within the last five years, instrumentation has been made available which now makes it practical for use to study the outer few 100A of layers and characterize it completely from a chemical, physical, and crystallographic standpoint. The scanning electron microscope (SEM) provides a means of viewing the surface of a material in situ to magnifications as high as 250,000X.

Spindle Fibres

The mitotic apparatus is a structure of obvious biological and medical interest, but it has proved to be a difficult cellular machine to understand. The chemical composition of the spindle is only slightly elucidated, largely because of the difficulties in preparing useful isolates of the structure. Chemical studies of the mitotic spindle have been reviewed elsewhere (Mcintosh, 1977), and will not be discussed further here. One would think that structural studies on the mitotic apparatus (MA) in situ would be straightforward, but even with this approach there is some disagreement in the results obtained with various methods and by different investigators. In this paper I will review briefly the approaches which have been used in structural studies of the MA, pointing out the strengths and problems of each approach. I will summarize the principal findings of the different methods, and identify what seem to be fruitful avenues for further work.

Probe Analysis

Electron probe analysis of frozen dried cryosections of frog skeletal muscle, rabbit vascular smooth muscle and of isolated, hyperpermeab1 e rabbit cardiac myocytes has been used to determine the composition of the cytoplasm and organelles in the resting state as well as during contraction. The concentration of elements within the organelles reflects the permeabilities of the organelle membranes to the cytoplasmic ions as well as binding sites. The measurements of [Ca] in the sarcoplasmic reticulum (SR) and mitochondria at rest and during contraction, have direct bearing on their role as release and/or storage sites for Ca in situ.
