Dion of Syracuse

Dion (/ˈdaɪɒn, ən/; Greek: Δίων ὁ Συρακόσιος; 408–354 BC), tyrant of Syracuse in Sicily, was the son of Hipparinus, and brother-in-law of Dionysius I of Syracuse. A disciple of Plato, he became Dionysius I's most trusted minister and adviser. However, his great wealth, his belief in Platonism and his ambition aroused the suspicions of Dionysius' son and successor, Dionysius II. An indiscreet letter from Dion to the Carthaginians led to his banishment. Settling in Athens, he lived a prosperous life until Dionysius dispossessed him of his estates and income. Landing in Sicily in 357 BC, he was successful in conquering Syracuse (other than the citadel). However, Dion soon quarrelled with the radical leader Heraclides and was forced into exile. Recalled in 355 BC, he became master of the whole city but his imperious behaviour and financial demands on the people of Syracuse soon alienated the population. His supporters abandoned him and he was assassinated. His attempts to liberate Sicily only brought political and social chaos to the island which would last for nearly 20 years.

Express (weaponry)

The term express was first applied to hunting rifles and ammunition beginning in the middle 19th century, to indicate a rifle or ammunition capable of higher than typical velocities. The early express cartridges used a heavy charge of black powder to propel a lightweight, often hollow point bullet, at high velocities to maximize point blank range. Later the express cartridges were loaded with nitrocellulose based gunpowder, leading to the Nitro Express cartridges, the first of which was the .450 Nitro Express.

The term express is still in use today, and is applied to rifles, ammunition, and a type of iron sight. With the widespread adoption of small bore, high velocity rifle cartridges, the meaning of express has shifted in modern usage, and refers to high velocity, large bore rifles and ammunition, typically used for hunting large or dangerous game at close range.

History

The name originates with a rifle built by James Purdey in 1856 (based on a pattern established a year earlier by William Greener) and named the Express Train, a marketing phrase intended to denote the considerable velocity of the bullet it fired. It was not the first rifle or cartridge of this type but it was Purdey's name express that stuck.

Ekspress

Ekspress (Russian: Экспресс meaning Express), is a series of geostationary communications satellites owned by Russian State Company for Satellite Communications. The first satellite of this kind was launched on October 13, 1994. The satellites are produced by the company JSC Information Satellite Systems.

Overview

The Ekspress series of communication satellites (industry code 11F639) was developed by the satellite company NPO PM as a replacement for the old Gorizont series of comsats. The first satellite of the series, Ekspress 1, was launched in 1994. It had a mass of 2.5 tons, 17 channels and an operational lifetime of at 5–7 years.

Starting in the mid-1990s, NPO PM started to make significant effort to close the technology gap between Russian and Western communication satellites. Cooperation with the French company Alcatel (now Thales Alenia Space) was begun in 1995. The first satellite of a new second series, Ekspress A-1, had 12 Alcatel-built transponders. It was lost in a rocket failure in 1999, but a replacement, Ekspress A-2 was successfully launched in March, 2000.
