A flexible structure is applied to improve the lubrication performance of a misaligned journal bearing.The journal bearing is ventilationstejp a representative sliding bearing, and there is damage due to metal-to-metal contact as a result of misalignment.Since misalignment is an unavoidable phenomenon, a journal bearing with a flexible structure wa

We report a self-phase-locked and degenerate backward wave optical parametric oscillator (BWOPO) generating a counterpropagating signal and an idler in the spectral band of optical communication.The device is based 12n/1200 wella on a periodically poled Rb-doped KTiOPO4 crystal with a poling period of 433 nm.To the best of our knowledge, this is th

Abstract Diets consisting of greater quantity/diversity of phytochemicals are correlated with reduced risk of disease.This understanding guides policy development increasing awareness of the importance of consuming fruits, grains, and vegetables.Enacted policies presume uniform concentrations of phytochemicals across crop varieties regardless of pr

The integration of inverter-based renewable energy sources into power grids presents a unique challenge: a reduction click here in grid inertia, leading to potential frequency stability issues.This paper introduces an innovative approach to address this challenge, focusing on the dynamic role of wind power plants equipped with dual-fed induction ge

The erva-mate (Ilex paraguariensis A.St.-Hil.) remtavares.com has a social, cultural and economic importance in the southern states of Brazil.The pure stands of this culture was responsible for the increase of many species of insects.Hedypathes betulinus (Klug, 1825) (Coleoptera: Cerambycidae) is considered the main pest from an economic viewpoint
