Re: General Quiz

Hi,

#7213. The term denotes softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of available phosphate, calcium, and vitamin D, or because of resorption of calcium. The impairment of bone metabolism causes inadequate bone mineralization. It in children is known as rickets, and because of this, use of the term is often restricted to the milder, adult form of the disease. Signs and symptoms can include diffuse body pains, muscle weakness, and fragility of the bones. Name the medical term.

#7214. What is 'Ebola virus disease' (EVD), also known as 'Ebola hemorrhagic fever' (EHF) or simply 'Ebola'?

Hi,

#7215. Name the element which was discovered in 1898 by Marie and Pierre Curie, when it was extracted from the uranium ore pitchblende and identified solely by its strong radioactivity: it was the first element to be so discovered. It was named after Marie Curie's homeland of Poland.

#7216. Name the English mathematician and writer (10 December 1815 – 27 November 1852), chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and one of the first computer programmers.

#7252.

He formally defined the reverberation time, which is still the most important characteristic currently in use for gauging the acoustical quality of a room, as number of seconds required for the intensity of the sound to drop from the starting level, by an amount of 60 dB (decibels).
