Flame

A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic reaction taking place in a thin zone. Very hot flames are hot enough to have ionized gaseous components of sufficient density to be considered plasma.

Mechanism

Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize. In this state they can then readily react with oxygen in the air, which gives off enough heat in the subsequent exothermic reaction to vaporize yet more fuel, thus sustaining a consistent flame. The high temperature of the flame causes the vaporized fuel molecules to decompose, forming various incomplete combustion products and free radicals, and these products then react with each other and with the oxidizer involved in the reaction. Sufficient energy in the flame will excite the electrons in some of the transient reaction intermediates such as CH and C₂, which results in the emission of visible light as these substances release their excess energy (see spectrum below for an explanation of which specific radical species produce which specific colors). As the combustion temperature of a flame increases (if the flame contains small particles of unburnt carbon or other material), so does the average energy of the electromagnetic radiation given off by the flame (see Black body).

Ninja

A ninja (忍者) or shinobi (忍び) was a covert agent or mercenary in feudal Japan. The functions of the ninja included: espionage, sabotage, infiltration, assassination and guerrilla warfare. Their covert methods of waging irregular warfare were deemed "dishonorable" and "beneath" the samurai-caste, who observed strict rules about honor and combat. The shinobi proper, a specially trained group of spies and mercenaries, appeared in the Sengoku or "warring states" period, in the 15th century, but antecedents may have existed in the 14th century, and possibly in the 12th century (Heian or early Kamakura era).

In the unrest of the Sengoku period (15th–17th centuries), mercenaries and spies for hire became active in the Iga Province and the adjacent area around the village of Kōga, and it is from the area's clans that much of our knowledge of the ninja is drawn. Following the unification of Japan under the Tokugawa shogunate (17th century), the ninja faded into obscurity. A number of shinobi manuals, often based on Chinese military philosophy, were written in the 17th and 18th centuries, most notably the Bansenshukai (1676).

USS Catamount (LSD-17)

USS Catamount (LSD-17) was a Casa Grande-class dock landing ship of the United States Navy, named in honor of the Catamount Tavern in Old Bennington, which served as headquarters for Ethan Allen's Green Mountain Boys while making their plans against the New Yorkers and the British. The Catamount was also the meeting place of Vermont's only form of government then: the Vermont Council of Safety.

Catamount was launched on 27 January 1945 by Newport News Shipbuilding and Dry Dock Co., Newport News, Va., sponsored by Mrs. Dave E. Satterfield, Jr.; commissioned on 9 April 1945, Commander C. A. Swafford in command; and reported to the U.S. Pacific Fleet.

Catamount sailed out of Pearl Harbor on 16 June 1945 laden with landing craft for Guam and Eniwetok. Through the remainder of the war, she ferried landing craft, dredges, and other equipment from Espiritu Santo to Kwajalein, Guam, and the Philippines. On 19 August she cleared Guam with special equipment to be used in the occupation of Japan, and on 26 August she stood up Tokyo Bay. Here she operated a boat pool and tended landing craft until 6 October, when she cleared on the first of two voyages to Manila to ferry troops and boats for the Japanese occupation. After a final voyage from Guam to Samar, Catamount cleared for San Francisco and Norfolk, where she arrived 11 February 1946. Joining the Atlantic Fleet, Catamount took part in amphibious training and midshipman cruises until the outbreak of the Korean War.

Shogun

A Shogun (将軍, Shōgun, [ɕoːɡu͍ɴ], "general", literally "military commander") was a hereditary military dictator in Japan during the period from 1192 to 1867. In this period, the shoguns were the de facto rulers of the country, although nominally they were appointed by the Emperor as a formality. The Shogun held almost absolute power over territories through military means, in contrast to the concept of a colonial governor in Western culture. Nevertheless, an unusual situation occurred in the Kamakura period (1199-1333) upon the death of the first shogun, whereby the Hōjō clan's hereditary titles of Shikken and Tokuso (1256-1333) monopolized the shogunate, collectively known as the Regent Rule (執権政治). The shogun during this period met the same fate as the Emperor and was reduced to a figurehead until a coup in 1333, when the shogun was restored to power.

The modern rank of shogun is roughly equivalent to a generalissimo. The title of shogun, is the short form of Sei-i Taishōgun (征夷大将軍, literally "Commander-in-Chief of the Expeditionary Force Against the Barbarians"); the individual governing the country at various times in the history of Japan, ending when Tokugawa Yoshinobu relinquished the office to the Emperor Meiji in 1867.
