QUES: Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. While the metal itself is radioactive, its high density makes it more effective than lead in halting radiation from strong sources such as radium. Other uses of depleted uranium include counterweights for aircraft control surfaces, as ballast for missile re-entry vehicles and as a shielding material. Due to its high density, this material is found in inertial guidance systems and in gyroscopic compasses. Depleted uranium is preferred over similarly dense metals due to its ability to be easily machined and cast as well as its relatively low cost. The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity (uranium being only a weak alpha emitter).

What is a strong source of radiation that is blocked by depleted uranium?
What is the answer?
ANS: radium
QUES: T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: By Constantius's order, the sole ruler of The Roman Empire at the death of his brother Constans, the Council of Arles in 353, was held, which was presided over by Vincent, Bishop of Capua, in the name of Pope Liberius. The fathers terrified of the threats of the Emperor, an avowed Arian, they consented to the condemnation of Athanasius. The Pope refused to accept their decision, and requested the Emperor to hold another Council, in which the charges against Athanasius could be freely investigated. To this Constantius consented, for he felt able to control it, at Milan. Milan was named as the place, here three hundred bishops assembled, most from the West, only a few from the East, in 355. They met in the Church of Milan. Shortly, the Emperor ordered them to a hall in the Imperial Palace, thus ending any free debate. He presented an Arian formula of faith for their acceptance. He threatened any who refused with exile and death. All, with the exception of Dionysius (bishop of Milan), and the two Papal Legates, viz., Eusebius of Vercelli and Lucifer of Cagliari, consented to the Arian Creed and the condemnation of Athanasius. Those who refused were sent into exile. The decrees were forwarded to the Pope for approval, but were rejected, because of the violence to which the bishops were subjected.

Did the Pope agree with this order?
What is the answer?
ANS: Pope refused to accept
QUES: Since the 19th century, the built-up area of Paris has grown far beyond its administrative borders; together with its suburbs, the whole agglomeration has a population of 10,550,350 (Jan. 2012 census). Paris' metropolitan area spans most of the Paris region and has a population of 12,341,418 (Jan. 2012 census), or one-fifth of the population of France. The administrative region covers 12,012 km (4,638 mi), with approximately 12 million inhabitants as of 2014, and has its own regional council and president.
