Coronal dimmings in both micro and macro scales, can be observed by extreme ultraviolet images, recorded from Solar Dynamics Observatory or Atmospheric Imaging Assembly (SDO/AIA).Mini-dimmings are sometimes associated with wave-like brightening, called coronal mass ejections.Here, the sun full disk images with 171 Å wavelenght, cadence of 2.5
The current pandemic of COVID-19 has caused havoc all over world since its emergence and rapid spread.Within three months the virus SARS-CoV-2 which was isolated from pneumonia cases in Wuhan City, Hubei Province, China in late December 2019, has affected almost all countries.India reported its first case of COVID-19 from state of Kerala on January
During railway operations, changes in the support conditions of sleepers, owing to various internal and external factors, can damage rails and concrete sleepers and alter the structural characteristics of gravel-ballasted tracks.However, current methods for evaluating gravel ballast conditions primarily rely on visual inspection.This study proposes
Environmental awareness and the need for sustainable construction inspired researchers and practitioners to explore innovative alternatives that might reduce greenhouse gas emissions and energy use related to excessive structural work.One such alternative is the utilization of Fiber-Reinforced Polymer (FRP) bars as a reinforcement in reinforced con
