Raymond Vahan Damadian
Raymond Vahan Damadian (March 16, 1936 – August 3, 2022) was an American physician, medical practitioner, and inventor of an NMR (nuclear magnetic resonance) scanning machine. Damadian's research into sodium and potassium in living cells led him to his first experiments with nuclear magnetic resonance (NMR) which caused him to first propose the MR body scanner in 1969. Damadian discovered that tumors and normal tissue can be distinguished in vivo by nuclear magnetic resonance (NMR) because of their prolonged relaxation times, both T1 ( spin-lattice relaxation) or T2 ( spin-spin relaxation). Damadian was the first to perform a full-body scan of a human being in 1977 to diagnose cancer. Damadian invented an apparatus and method to use NMR safely and accurately to scan the human body, a method now well known as magnetic resonance imaging (MRI). Damadian received several prizes. In 2001, the Lemelson-MIT Prize Program bestowed its $100,000 Lifetime Achievement Award on Damadian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Altar Call
An altar call is a tradition in some Christian churches in which those who wish to make a new spiritual commitment to Jesus Christ are invited to come forward publicly. It is so named because the supplicants gather at the altar located at the front of the church building. Most altar calls occur at the end of an evangelical address. Background Altar calls are a recent historic phenomenon beginning in the 1830s in America. During these, people approached the chancel rails, anxious seat, or mourner's bench to pray. One of the most famous 19th century revivalists, Charles Grandison Finney, "popularized the idea of the 'altar call' in order to sign up his converts for the abolition movement." In many Churches of the Wesleyan-Arminian theology, the altar call, in addition to being an invitation for people to experience the New Birth, is also often used to implore believers to experience the second work of grace, known as entire sanctification. Notable examples in history of using a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tennis
Tennis is a racket sport that is played either individually against a single opponent ( singles) or between two teams of two players each ( doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have ...

Armenians
Armenians ( hy, հայեր, ''hayer'' ) are an ethnic group native to the Armenian highlands of Western Asia. Armenians constitute the main population of Armenia and the ''de facto'' independent Artsakh.
