Rolled homogeneous armour

Rolled homogeneous armor (RHA) is a type of armor made of a single steel composition, as opposed to layered or cemented armor. Its first common application was in tanks. It fell out of use after World War II as new anti-tank rounds were developed, against which it was ineffective.

Composition

Armored steel must be hard, yet resistant to shock, in order to resist high velocity metal projectiles. Steel with these characteristics is produced by processing cast steel billets of appropriate size and then rolling them into plates of required thickness. Hot rolling homogenizes the grain structure of the steel, removing imperfections which would reduce the strength of the steel. Rolling also elongates the grain structure in the steel to form long lines, which spreads stress loaded onto the steel throughout the metal, avoiding a concentration of stress in one area.

RHA is called homogeneous armor because its structure and composition is uniform throughout its thickness. The opposite of homogeneous steel plate is cemented or face-hardened steel plate, where the face of the steel is composed differently from the substrate. The face of the steel, which starts as an RHA plate, is hardened by a heat-treatment process.

Mille (woreda)

Mille is one of the woredas in the Afar Region of Ethiopia. It is named for the Mille River, a tributary of the Awash River, which flows through this woreda. Part of the Administrative Zone 1, Mille is bordered on the south by the Administrative Zone 3, on the southwest by Administrative Zone 5, on the west by the Amhara Region, on the northwest by Chifra, on the northeast by Dubti, and on the southeast by the Somali Region. Towns in Mille include Mille and Eli Wuha. The highest point in this woreda is Mount Gabillema (1459 meters), a dormant volcano in the southeastern part. Roads in this woreda include the feeder road between Chifra and Mille, which is 105 kilometers in length; it was constructed in two segments between February 1999 and February 2001 by SUR Construction. Important local landmarks include the Yangudi Rassa National Park, which covers the southeast corner of Mille, but not Mount Gabillema; and the archeological sites at Hadar and Dikika where specimens of Australopithecus afarensis have been recovered.

Mille (card game)

Mille is a two-player card game requiring two standard 52-card decks. Mille is a rummy game similar to canasta in the respects that if a player picks up cards from the discard pile, the player picks up the entire pile, and the only legal melds are three or more cards of a same rank.

Origins

The two-player rummy game Mille is said to have been devised in Montreal,Québec and from there brought to Toronto in the 1990s. It has since become increasingly popular.

Basic rules

The dealer deals 15 cards to his opponent and himself, then turns over a card from the deck.

On a player's turn, he has two options: pick up the "pack", or draw a card from the deck. If the player has a pair in his hand of the last card discarded, he has the option of picking the pack up. The only exception to this rule is if the up card opened immediately after the deal is a 2. The player can pick it up; he doesn't have to use it immediately or have a pair of 2's. When picking up the pack, the player must immediately lay the pair in his hand and the last card discarded. For example: The pack is 3-4-5-K-3-7. One player discards a 9. The other player has a pair of 9's in his hand. He can take the 9 from the pack, lay the pair of 9's on the table with the discarded 9, then pick up the 3-4-5-K-3-7 and place in his hand.
