Carina Negrone
The marchioness Carina Massone Negrone (Bogliasco, 20 June 1911 - Bogliasco, 19 March 1991) was an Italian aviator. She is considered to be one of the first ''heroines of the sky''. Biography Married to the marquis Ambrogio Negrone (with whom she had a son, Vittorio), she was the first Italian woman to obtain (in 1933) a pilot's license from the Reale Unione Nazionale Aeronautica (RUNA). A keen sportswoman (swimming, ski, tennis), she preferred flying, an activity that at the time was mainly practised by men, the intended interpreters of the manly dynamism encouraged by Futurism and Fascism. On 5 May 1934, she established her first personal record by flying at an altitude of 5,544 metres with a ''Class C'' seaplane. Following this achievement and with the support of her friend Italo Balbo, she decided to attempt to beat Maryse Hilsz's world record of 11,289 metres. As preparation, she trained as an air force pilot at Guidonia Montecelio airport. On 20 June 1935, Carina took off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marchesa
A marquess (; french: marquis ), es, marqués, pt, marquês. is a nobleman of high hereditary rank in various European peerages and in those of some of their former colonies. The German language equivalent is Markgraf (margrave). A woman with the rank of a marquess or the wife (or widow) of a marquess is a marchioness or marquise. These titles are also used to translate equivalent Asian styles, as in Imperial China and Imperial Japan. Etymology The word ''marquess'' entered the English language from the Old French ("ruler of a border area") in the late 13th or early 14th century. The French word was derived from ("frontier"), itself descended from the Middle Latin ("frontier"), from which the modern English word ''march'' also descends. The distinction between governors of frontier territories and interior territories was made as early as the founding of the Roman Empire when some provinces were set aside for administration by the senate and more unpacified or vulnerabl ...

Airport
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commemorative Stamp
A commemorative stamp is a postage stamp, often issued on a significant date such as an anniversary, to honor or commemorate a place, event, person, or object. The ''subject'' of the commemorative stamp is usually spelled out in print, unlike definitive stamps which normally depict the subject along with the denomination and country name only. Many postal services issue several commemorative stamps each year, sometimes holding first day of issue ceremonies at locations connected with the subjects. Commemorative stamps can be used alongside ordinary stamps. Unlike definitive stamps that are often reprinted and sold over a prolonged period of time for general usage, commemorative stamps are usually printed in limited quantities and sold for a much shorter period of time, usually, until supplies run out. First commemoratives There are several candidates for the title of the first commemorative. A 17-cent stamp issued in 1860 by New Brunswick, showing the Prince of Wales in anti ...

Macchi M
Aermacchi was an Italian aircraft manufacturer. Formerly known as Aeronautica Macchi, the company was founded in 1912 by Giulio Macchi at Varese in north-western Lombardy as Nieuport-Macchi, to build Nieuport monoplanes under licence for the Italian military. With a factory located on the shores of Lake Varese, the firm originally manufactured a series of Nieuport designs, as well as seaplanes. After World War II, the company began producing motorcycles as a way to fill the post-war need for cheap, efficient transportation. The company later specialised in civil and military pilot training aircraft. In July 2003, Aermacchi was integrated into the Finmeccanica Group (now Leonardo) as Alenia Aermacchi, which increased its shareholding to 99%. Military trainers Since the beginning, the design and production of military trainers have been the core business of Alenia Aermacchi. The products include: * SF-260, piston-engined or turboprop-powered screener/primary trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Celsius
The degree Celsius is the unit of temperature on the Celsius scale (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale in 1742. Before being renamed in 1948 to honour Anders Celsius, the unit was called ''centigrade'', from the Latin ''centum'', which means 100, and ''gradus'', which means steps. Most major countries use this scale; the other major scale, Fahrenheit, is still used in the United States, some island territories, and Liberia. The Kelvin scale is of use in the sciences, with representing absolute zero. Since 1743 the Celsius scale has been based on 0 °C for the freezing ...

Rarefaction
Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves ( sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture). Rarefaction waves expand with time (much like sea waves spread out as they reach a beach); in most cases rarefaction waves keep the same overall profile ('shape') at all times throughout the wave's movement: it is a ''self-similar expansion''. Each part of the wave travels at the local speed of sound, in the local medium. This expansion behaviour contrasts with that of pressure increases, which gets narrower with time until they steepen into shock waves. When angle of incidence is greater than angle of refraction, then light travels from denser to rarer medium. When angle of incidence is smaller than angle of refraction then light travels from rarer to denser medium Physical examples A n ...
