PURPOSE: To conduct a feasibility study of the safety and efficacy corneal contouring inlay as treatment for emmetropic presbyopia. METHODS: The Raindrop (ReVision Optics, Inc., Lake Forest, CA) was implanted on stromal bed beneath keratotomy flap in 20 nondominant eyes patients. implant is designed to cause change curvature overlying cornea, with subsequent multifocal refractive power. Efficacy outcome defined at least 75% uncorrected near visual acuity 0.3 logMAR (20/40 Snellen) or better...
En Colombia, el Departamento Nacional de Planeación proyectó para 2018, 20% en aprovechamiento residuos que van a los rellenos e incentivar reciclaje, sin embargo no ha logrado superar 17%, por lo tanto es prioritario incluir mecanismos articulación del componente productivo y investigación científica tecnológica. este artículo se relacionan importantes fuentes agroindustriales presentando algunas alternativas subproductos las aprovechan sus características propiedades obtener materiales...
Background The w Mel strain of Wolbachia has been successfully introduced into Aedes aegypti mosquitoes and shown to reduce the transmission dengue other -borne viruses. Here we report entomological results from phased, large-scale releases infected Ae . throughout three contiguous cities located in Aburrá Valley, Colombia. Methodology/principal findings Local -infected were generated then released an initial release pilot area 2015–2016, which resulted establishment local mosquito...
ABSTRACT We present a pan-chromatic study of AT2017bcc, nuclear transient that was discovered in 2017 within the skymap reported burst-like gravitational-wave candidate, G274296. It initially classified as superluminous supernova, and then reclassified candidate tidal disruption event. Its optical light curve has since shown ongoing variability with structure function consistent an active galactic nucleus, however, earlier data show no for at least 10 yr prior to outburst 2017. The spectrum...
BackgroundInvasive pneumococcal disease (IPD) is the leading cause of infectious death worldwide. This study aimed to describe epidemiology IPD and impact conjugate vaccine-10 (PCV-10) over a 10-year period in Bogotá, Colombia.MethodsThis was laboratory-based surveillance Streptococcus pneumoniae isolated from patients with 82 hospitals 10 years Colombia. Data were compared between two periods: 2007–2011 (before introduction PCV-10) 2012–2017 (after PCV-10).ResultsIn total, 1670 included...
The FP7 AdVanced Aerodynamic Tools for lArge Rotors - Avatar project aims to develop and validate advanced aerodynamic models, be used in integral design codes the next generation of large scale wind turbines (10-20MW). One approaches towards reaching rotors 10-20MW size is application flow control devices, such as flaps. In Task 3.2: Development modelling devices on aerofoils and, project, are benchmarked validated against experimental data a DU95W180 airfoil steady unsteady flow, different...
Euterpe oleracea es una palma originaria de Suramerica, su distribucion netamente tropical y subtropical. Su fruto altamente aprovechado en Brasil, donde se conoce como acai. Comercializado tanto dentro fuera del pais, sus niveles exportacion han aumentado debido a resultados cientificos que indican altas propiedades antioxidantes nutritivas. Es considerado alimento funcional importancia el sostenimiento la seguridad alimentaria. En Colombia, E hace presencia region pacifica, principalmente...
SN 2018hti was a very nearby (z=0.0614) superluminous supernova with an exceedingly bright absolute magnitude of -21.7 mag in r-band at maximum. The densely sampled pre-maximum light curves show slow luminosity evolution and constrain the rise time to ~50 rest-frame days. We fitted synthetic photometry infer physical parameters explosion for both magnetar CSM-interaction scenarios. conclude that one two mechanisms could be powering 2018hti; interaction ~10 Msun circumstellar material or...

Propóleos es uno de los productos la colmena que actualmente viene ganando interés por parte investigadores, ya sus propiedades fisicoquímicas y biológicas, han sido ampliamente reconocidas su capacidad terapéutica contra una variedad patógenos humanos animales, al igual uso potencial varios Fitopatógenos. Los estudios demuestran propóleos sustancia compleja, constituida, en promedio, 300 compuestos diferentes, esta riqueza está correlacionada con el origen botánico del cual se obtienen las...
La gallinaza fresca, debido a su rapida disponibilidad esta siendo ampliamente utilizada como fuente exclusiva de nutrientes, especialmente nitrogeno (N), en el cultivo cebolla ( Allium fistulosum ), sin embargo, problemas toxicidad por sales y acumulacion metales pesados plantas han sido detectados. El objetivo este trabajo fue estimar efecto la fresca compostada sobre las bacterias Azotobacter sp. Azospirillum , asi numero esporas hongos micorrizicos arbusculares (HMA), cebolla. En...
The availability of natural gas in Lima — Peru, from Camisea, several urban areas Lima, for technical reasons there are no facilities especially peripheral the highlands or hills. This is compensated by FISE government social programs providing subsidized liquefied petroleum balls. In this context, a proposal has been developed to provide these elevated areas, particular Cerro San Cristóbal, located boundaries districts Rímac and Juan de Lurigancho Lima. based on principles Lean Logistic...
<p>Fue evaluada la presencia de bacterias fijadoras nitrógeno (diazotróficas) en tres mezclas residuos con proporciones diferentes compost cachaza, arena y carbonilla; iguales cascarilla arroz bagazo caña:<br />M1 (40, 10, 20, 20 respectivamente), M2 (20, 0, 40, M3 (10, respectivamente).

<p>El nitrógeno (N) es el nutriente más importante en términos de consumo fertilizantes. La excesiva adición N a través fertilizantes y sus efectos nocivos ambiente preocupación científicos, ambientalistas, gobiernos, industria cuerpos internacionales. El fortalecimiento investigación aprovechamiento la fijación biológica (FBN) gana espacio como alternativa agricultura sustentable nivel global. En esta se encontró que interacción bacterias fijadoras (diazotróficas) con diversos...
We present the results from an extensive follow-up campaign of Tidal Disruption Event (TDE) ASASSN-15oi spanning $\delta t \sim 10 - 3000$ d, offering unprecedented window into multiwavelength properties a TDE during its first $\approx 8$ years evolution. is one few TDEs with strong detections at X-ray, optical/UV, and radio wavelengths featured two delayed flares 180$ d 1400$ d.
