(2019-06-01)
Aim: At performing a temporal analysis of the distribution pattern of islet endocrine cells and antioxidant enzymes in diabetic rats during the post-natal critical development window. Main methods: The newborns received ...
ALMA band 1 optics (35-50 GHz): tolerance analysis, effect of cryostat infrared filters and cold beam measurements
(Springer, 2017)
The Atacama Large Millimeter/Sub-millimeter Array (ALMA) is currently the largest (sub-)mm wave telescope in the world and will be used for astronomical observations in all atmospheric windows from 35 to 950 GHz when ...
Microdomain orientation dependence on thickness in thin films of cylinder-forming PS-b-PMMA
(Iop Publishing, 2010-04-09)
The self-assembly of block-copolymer thin films in periodic nanostructures has received considerable attention during the last decade due to their potential applications in nanofabrication and nanolithography. We followed ...
Contuse lesion of the rat spinal cord of moderate intensity leads to a higher time-dependent secondary neurodegeneration than severe one - An open-window for experimental neuroprotective interventions
(CHURCHILL LIVINGSTONE, 2008)
Secondary neurodegeneration takes place in the surrounding tissue of spinal cord trauma and modifies substantially the prognosis, considering the small diameter of its transversal axis. We analyzed neuronal and glial ...

(SAGE Publications, 2015)
In Peru, a significant proportion of people tested for HIV and syphilis do not receive timely results. Our Objetive: was to assess the institutional feasibility of implementing simultaneous HIV/syphilis point-of-care tests ...
Fingerprint Database Variations for WiFi Positioning
(IJCT Foundation, 2013-12)
Indoor positioning systems calculate the position of a mobile device (MD) in an enclosed environment with relative precision. Most systems use WiFi infrastructure and several positioning techniques, where the most commonly ...
Heat Exchange from the Toucan Bill Reveals a Controllable Vascular Thermal Radiator
(Amer Assoc Advancement Science, 2009-07-24)
The toco toucan (Ramphastos toco), the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, from serving as a ...
Design of a Comb Generator for High Capacity Coherent-WDM Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
This paper presents a theoretical model developed for estimating the power, the optical signal to noise ratio and the number of generated carriers in a comb generator, having as a reference the minimum optical signal do ...
Microhardness of dual-polymerized resin cement around a translucent fiber post in the intraradicular environment
(2011-10-01)
Aim: In this study, we evaluated the effect of photopolymerization on Vickers microhardness of dual-polymerized resin cement at three locations when a translucent quartz fiber post was used. Materials and Methods: Single-rooted ...
Influence of COVID-19 confinement on physics learning in engineering and science students
(Journal of Physics: Conference SeriesColombia, 2020-11-05)
Due to the global alert about the risk of contagion and propagation of Covid-19, a situation that has changed in the educational processes, this has forced the system to migrate towards a more dynamic and connected model ...
