Giuseppe Biagi (explorer)
Giuseppe Biagi (2 February 1897 in Medicina – 1 November 1965 in Rome) was an Italian soldier, explorer and radio operator. He took part in Umberto Nobile's expedition to the North Pole in the airship ''Italia'' in May 1928. Biography Son of Raffaele Biagi and Virginia Natali, he was born and grew up at a farm in the Bolognese countryside, together with his brothers Cesira and Alfredo. In 1903 the family moved to Bologna, where he continued his studies at the Aldini technical institute ( it). In 1911, he started working on boats in Rimini, then decided to study radio telegraphy at Varignano Technical School, a port location near La Spezia where he later became an instructor. He participated as a radio-telegraph operator in the First World War, where he took the nickname ''Baciccia''. After the war ended, he married Anita Bucilli, and they had a son named Giorgio. In 1928 he participated in airship ''Italia'' polar expedition led by Nobile. On 24 May 1928 the airship crashed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicina
Medicina ( Bolognese: ; Eastern Bolognese: ) is an Italian ''comune'' with c. 16,000 inhabitants in the Metropolitan City of Bologna, part of the region of Emilia-Romagna. Name The origins of its name (which in Italian means "medicine") are quite uncertain, and many hypotheses have been put forward. A legend tells that the Emperor Frederick Barbarossa, passing through Medicina from Milan fell ill and miraculously recovered because of a snake that accidentally came into the pot of his soup. It has been proved, though, that Barbarossa did pass through Medicina but that the name of the town predates that time. In memory of this legend the '' Festa del Barbarossa'' ("Barbarossa's party") takes place every year on the 3rd weekend of September. Science A radio observatory named "Croce del Nord" (Cross of the North) is located near Medicina (in the village of Fiorentina). It is made up of an aerial, long, and of a much wider "cross". It is operated by the Istituto di Radioastronomia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Via Ostiensis
The Via Ostiensis ( it, via Ostiense) was an important road in ancient Rome. It ran west from the city of Rome to its important sea port of Ostia Antica, from which it took its name. The road began near the Forum Boarium, ran between the Aventine Hill and the Tiber River along its left (eastern) bank, and left the city's Servian Walls through the Porta Trigemina. When the later Aurelian Walls were built, the road left the city through the Porta Ostiensis (Porta San Paolo). In the late Roman Empire, trade suffered under an economic crisis, and Ostia declined as an important port. With the accompanying growth of importance of the Via Portuensis from the time of Constantine onwards, that of the Via Ostiensis correspondingly decreased. Modern Via Ostiense, following a similar path, is the main connection of Rome to Ostia (one of the quarters of Rome at present) together with the Via del Mare. On its way to Ostia, the road passes by the important basilica of Saint Paul Outside the Wal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filling Station
A filling station, also known as a gas station () or petrol station (), is a facility that sells fuel and engine lubricants for motor vehicles. The most common fuels sold in the 2010s were gasoline (or petrol) and diesel fuel. Gasoline pumps are used to pump gasoline, diesel, compressed natural gas, CGH2, HCNG, LPG, liquid hydrogen, kerosene, alcohol fuel (like methanol, ethanol, butanol, propanol), biofuels (like straight vegetable oil, biodiesel), or other types of fuel into the tanks within vehicles and calculate the financial cost of the fuel transferred to the vehicle. Besides gasoline pumps, one other significant device which is also found in filling stations and can refuel certain (compressed-air) vehicles is an air compressor, although generally these are just used to inflate car tires. Many filling stations provide convenience stores, which may sell confections, alcoholic beverages, tobacco products, lottery tickets, soft drinks, snacks, coffee, newspap ...

Krassin (1917 Icebreaker)
The first icebreaker ''Krassin'', or ''Krasin'', (russian: Красин) was built for the Imperial Russian Navy as ''Svyatogor''. She had a long, distinguished career in rescue operations, as well as a pathfinder and explorer of the Northern Sea Route. She has been fully restored to operating condition and is now a museum ship in Saint Petersburg. History The icebreaker was built by Armstrong Whitworth in Newcastle upon Tyne under the supervision of Yevgeny Zamyatin. (updates articles by Myers published in ''Slavonic and East European Review'') The vessel was launched as the ''Svyatogor'' on 3 August 1916 and completed in February 1917. Up to the beginning of the 1950s she remained the most powerful icebreaker in the world. During the allied intervention against the Bolsheviks in Northern Russia (1918–19) she was scuttled by Bolshevik forces to block the port at Arkhangelsk. The Royal Navy raised her for use in the White Sea and later brought her to England. She was moved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio San Paolo
The Regia Marina Radiotelegraphic Station, better known as Radio San Paolo, was a long, medium and short wave Italian military broadcaster and military reception center located on the southern outskirts of Rome. Inaugurated in 1917 under the command of Regia Marina, the station remained in Navy service for much of the Second World war and then lost its importance until the disposal and transformation of its premises into civilian flats. History The center was established towards the end of the first decade of the twentieth century to intensify communications with the colonies Italian on the Red Sea. The chosen location was along Via Ostiense across from the current building at number 204 in an uninhabited area and about 250 meters beyond the basilica of St. Paul in the direction of the sea. The systems, installed under the supervision of Giancarlo Vallauri and marine lieutenants Giuseppe Pession and Bernardo Micchiardi, were high-power long wave arched Poulsen transmi ...

Radio Receiver
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems that use radio. The information produced by the receiver may be in the form of sound, video (television), or digital data. A radio receiver may be a separate piece of electronic equipment, or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for Communication engineering, communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortwave Radio
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines ( line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave broadcasts of radio programs played an important role in the early days of radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italia (airship)
The ''Italia'' was a semi-rigid airship belonging to the Italian Air Force. It was designed by Italian engineer and General Umberto Nobile who flew the dirigible in his second series of flights around the North Pole. The ''Italia'' crashed in 1928, with one confirmed fatality from the crash, one fatality from exposure while awaiting rescue, and six missing crew members who were trapped in the still-airborne envelope. At the end of the rescue operations there were a total of 17 dead (crew and rescuers). Design and specifications ''Italia'' was an N-class semi-rigid airship, designation N-4. It was almost identical in design to the N-1 but slightly larger in gas capacity. * First flight: 1928 * Length: * Diameter: * Gas capacity: * Performance: * Payload: * Power plant: 3 Maybach diesel engines, total Polar expedition At the end of 1927, after much insistence, Nobile gained permission to use this airship for a new scientific expedition to the North Pole under the ae ...
