This work presents an optoelectronic instrument designed for wireless visible light communication (WVLC) systems, operating within a wavelength range of 380-750 nm and compatible with standard radio frequency (RF) communication. The instrument encompasses two distinct architectures. The first enables the transmission and reception of RF-processed audio signals through a three-stage process involving RF signal transmission via Bluetooth, signal multiplexing using acousto-optic modulation, a sinusoidal grating, a PIN photodetector array, and final audio playback.

However, this evidence does not exist among members of the Seventh-day Adventist Church (SDA) in Latin America, particularly Peru. This study evaluated the association between religious involvement and vegetarian diet with mental well-being in members of the SDA Church in Peru.

Topaz (AlF(OH)SiO)/corundum (AlO) composites were prepared by a facile and novel reversible process from the sintering of synthetic topaz and AlF powders, with corundum formed into the topaz matrix. The corundum formation reaction occurs in the temperature range 875-975 °C, from 40 min sintering time, obtaining the topaz- AlF(OH)SiO/corundum- AlO composites. Although sintering temperature and time increment lead to higher corundum formation in the topaz matrix (78.
