Anadolu Feneri
__NOTOC__ Anadolu Feneri is a historical lighthouse still in use, which is located on the Asian side of Bosphorus' Black Sea entrance in Istanbul, Turkey. Anadolu is the Turkish name for Anatolia. It is across from the lighthouse Rumeli Feneri, which is on the European side of the strait at a distance of . A connecting line between the two lighthouses marks the northern boundary of the Port of Istanbul. The place, where the lighthouse stands, is named Anadolufeneri, which today is a fishermen's village in Beykoz district. History François Baron de Tott, a French engineer and military officer of Hungarian origin, who lived some years in Istanbul, reported on the existence of a lighthouse at this location in 1755. During the Crimean War (1853–1856), it became necessary to have lighthouses on both sides of the Black Sea entrance of Bosporus to provide safe navigation for the French and British war ships. The French constructed Rumeli Feneri on the opposite side of the strait ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beykoz
Beykoz (), also known as Beicos and Beikos, is a district in Istanbul, Turkey at the northern end of the Bosphorus on the Anatolian side. The name is believed to be a combination of the words bey and ''kos'', which means "village" in Farsi. Beykoz includes an area from the streams of Küçüksu and Göksu (just before Anadoluhisarı) to the opening of the Bosphorus into the Black Sea, and the villages in the hinterland as far as the Riva creek. The mayor is Murat Aydın ( AKP). History The mouth of the Bosphorus in ancient times was used as a place of sacrifice, specifically to petition Zeus and Poseidon for a safe journey across the Black Sea, without which no one would venture into those stormy waters. The first people to settle the upper-Bosphorus were Thracians and Greeks and the ancient name for the area was Amikos (Αμικός in Greek) or Amnicus (Αμνικός), named after a Thracian king. However, the area has changed hands many times since. As well as being a str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yum Burnu
{{Short description, Turkish Cape at the Bosphorus Yum Burnu ( Turkish 'Cape of Good Hope'), the ancient Ancyræan Cape or Ancyræan Promontory and the modern Greek Cape Psomion, is the cape at the northeast end of the Bosphorus, where it enters the Black Sea. It is a bold headland descending almost perpendicularly into the water.''The Black Sea Pilot'', 192 p. 320 Just below it is a reef A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water.

Lighthouses Of The Black Sea
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attractions In Istanbul
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 ...

Towers Completed In 1755
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Butane
Butane () or ''n''-butane is an alkane with the formula C4H10. Butane is a gas at room temperature and atmospheric pressure. Butane is a highly flammable, colorless, easily liquefied gas that quickly vaporizes at room temperature. The name butane comes from the root but- (from butyric acid, named after the Greek word for butter) and the suffix -ane. It was discovered by the chemist Dr. Walter Snelling in 1912. It was found dissolved in crude petroleum in 1864 by Edmund Ronalds, who was the first to describe its properties. Butane is one of a group of liquefied petroleum gases (LP gases). The others include propane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Butane burns more cleanly than gasoline and coal. Density The density of butane is highly dependent on temperature and pressure in the reservoir. For example, the density of liquid phase is 571.8±1 kg/m3 (for pressures up to 2MPa and temperature 27±0.2 °C), while the density of liq ...

Acetylene
Acetylene (systematic name: ethyne) is the chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbide
In chemistry, a carbide usually describes a compound composed of carbon and a metal. In metallurgy, carbiding or carburizing is the process for producing carbide coatings on a metal piece. Interstitial / Metallic carbides The carbides of the group 4, 5 and 6 transition metals (with the exception of chromium) are often described as interstitial compounds. These carbides have metallic properties and are refractory. Some exhibit a range of stoichiometries, being a non-stoichiometric mixture of various carbides arising due to crystal defects. Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: *When the metal atoms are cubic close-packed, (ccp), then filling all of the octahedral interstices with carbon achieves 1:1 stoich ...

Dalén Light
A Dalén light is a light produced from burning of carbide gas (acetylene), combined with a solar sensor which automatically operates the light only during darkness. Overview The technology was the predominant form of light source in lighthouses from the 1900s through the 1960s, when electric lighting had become dominant. The system was invented by Gustaf Dalén and marketed by his company AGA. Dalén later invented the AGA cooker in 1922. The Dalén light is notable because of its sun valve (a.k.a. solar valve), which earned its inventor the Nobel prize in physics. The Carbide lamp was developed in the early 1900s. While the lamps proved useful in many applications, the problem of safely storing acetylene meant they needed regular refilling which constrained their use in applications such as lighthouses. Examples Lighthouses using Dalén lighting have included: * Barrenjoey Lighthouse, New South Wales (1932–1972) *Peninsula Point Light (1922–1936) Upper Peninsula Michigan ...
