The inelastic light scattering of the acoustic vibration of spherical nanoparticles is reviewed. For particles much smaller than the wavelength of the exciting light (?), with a diameter (d) smaller than about 20 nm, the dominant physical mechanism, calle... see more

Hemos realizado el estudio de la variación en presión por medio de la celda a yunques de diamante (DAC) hasta 16GPa, de los modos vibracionales acústicos del aceite multigrado para motor SUPRA SJ SAE 15W 40, que es un lubricante comercial de alta protecci... see more

Brillouin optical correlation-domain technologies are reviewed as “fiber optic nerve systems” for the health monitoring of large structures such as buildings, bridges, and aircraft bodies. The Brillouin scattering property is used as a sensing... see more

Specialty optical fibers employed in Brillouin-based distributed sensors are briefly reviewed. The optical and acoustic waveguide properties of silicate glass optical fiber first are examined with the goal of constructing a designer Brillouin gain spectru... see more

Reseña crìtica sobre el ensayo de José Amìcoa Un brillo concheperla. Teoría queer y literatura latinoamericana

All crystalline materials crystallize in one of seven crystalline systems which have different shapes and sizes. Why crystalline materials take particular forms of crystals and what make the atoms arrange themselves in these forms. Actually, until now the... see more

Over the past decade, several security issues with Linux Random Number Generator (LRNG) on PCs and Androids have emerged. The main problem involves the process of entropy harvesting, particularly at boot time. An entropy source in the input pool of LRNG i... see more

There is currently a renewed interest in the development of experimental methods to achieve the elastic characterization of thin films, multilayers and acoustic resonators operating in the GHz range of frequencies. The potentialities of surface Brillouin ... see more

El objetivo de la presente investigación fue analizar el síndrome visual informático (SVI) en los docentes peruanos de educación básica durante la pandemia por COVID-19. El enfoque fue cuantitativo, el diseño no experimental y el tipo descriptivo transecc... see more
