Ahırkapı Feneri
__NOTOC__ The Ahırkapı Feneri, a historical lighthouse still in use, is located at the southern Seraglio Point on the Rumelian coast of Bosporus' south entrance, in Ahırkapı neighborhood of Istanbul's Fatih district, Turkey. It is across from the Kadıköy İnciburnu Feneri, which is on the Anatolian coast of the strait at a distance of . A line connecting the two lighthouses marks the southern boundary of the Port of Istanbul. History It is told that a marine accident, which occurred near this location, led to the establishment of the lighthouse. In 1755, a merchant sail ship bound for Egypt ran aground off the shore of Kumkapı due to bad weather conditions in the night. Hearing of the ship grounding, Ottoman sultan Osman III (reigned 1754–1757) rushed to the scene, where a seaman complained about the lack of a lighthouse there that could provide safe navigation around the hazardous waters. On the sultan's order, a light fueled by olive oil was established by the Kapudan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatih
Fatih () is a district of and a municipality (''belediye'') in Istanbul, Turkey, and home to almost all of the provincial authorities (including the governor's office, police headquarters, metropolitan municipality and tax office) but not the courthouse. It encompasses the peninsula coinciding with old Constantinople. In 2009, the district of Eminönü, which had been a separate municipality located at the tip of the peninsula, was once again remerged into Fatih because of its small population. Fatih is bordered by the Golden Horn to the north and the Sea of Marmara to the south, while the Western border is demarked by the Theodosian wall and the east by the Bosphorus Strait. History Byzantine era Historic Byzantine districts encompassed by present-day Fatih include: ''Exokiónion'', ''Aurelianae'', ''Xerólophos'', '' ta Eleuthérou'', ''Helenianae'', ''ta Dalmatoú'', ''Sígma'', '' Psamátheia'', ''ta Katakalón'', ''Paradeísion'', ''ta Olympíou'', ''ta Kýrou'', '' ...

Olive Oil
Olive oil is a liquid fat obtained from olives (the fruit of ''Olea europaea''; family Oleaceae), a traditional tree crop of the Mediterranean Basin, produced by pressing whole olives and extracting the oil. It is commonly used in cooking: for frying foods or as a salad dressing. It can be found in some cosmetics, pharmaceuticals, soaps, and fuels for traditional oil lamps. It also has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine; the other two are wheat and grapes. Olive trees have been grown around the Mediterranean since the 8th millennium BC. In 2019–2020, world production of olive oil was . Spain was the largest producer followed by Italy, Tunisia, Greece, Turkey and Morocco. San Marino has by far the largest per capita consumption of olive oil worldwide. The composition of olive oil varies with the cultivar, altitude, time of harvest, and extraction process. It consists mainly of oleic acid (up to 83%), with ...

Sea Of Marmara
The Sea of Marmara,; grc, Προποντίς, Προποντίδα, Propontís, Propontída also known as the Marmara Sea, is an inland sea located entirely within the borders of Turkey. It connects the Black Sea to the Aegean Sea via the Bosporus and Dardanelles straits, separating the country's European and Asian sides. The Sea of Marmara is a small sea with an area of , and dimensions of . Its greatest depth is . Name The Sea of Marmara is named after the largest island to its south side which is called Marmara Island because it is rich in marble (Greek (''mármaron'') "marble)." In classical antiquity it was known as the Propontis, which is derived from the Greek words ''pro-'' (before) and ''pontos'' (sea) and reflects the fact that the Ancient Greeks used to sail through it to reach the Black Sea that they called Pontos. Mythology In Greek mythology, a storm on the Propontis brought the Argonauts back to an island they had left, precipitating a battle in which ...

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 ...

Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning "wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from pet ...

Cone (geometry)
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex. Depending on the author, the base may be restricted to be a circle, any one-dimensional quadratic form in the plane, any closed one-dimensional figure, or any of the above plus all the enclosed points. If the enclosed points are included in the base, the cone is a solid object; otherwise it is a two-dimensional object in three-dimensional space. In the case of a solid object, the boundary formed by these lines or partial lines is called the ''lateral surface''; if the lateral surface is unbounded, it is a conical surface. In the case of line segments, the cone does not extend beyond the base, while in the case of half-lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abdülmecid I
Abdulmejid I ( ota, عبد المجيد اول, ʿAbdü'l-Mecîd-i evvel, tr, I. Abdülmecid; 25 April 182325 June 1861) was the 31st Sultan of the Ottoman Empire and succeeded his father Mahmud II on 2 July 1839. His reign was notable for the rise of nationalist movements within the empire's territories. Abdulmejid wanted to encourage Ottomanism among secessionist subject nations and stop rising nationalist movements within the empire, but despite new laws and reforms to integrate non-Muslims and non-Turks more thoroughly into Ottoman society, his efforts failed in this regard. He tried to forge alliances with the major powers of Western Europe, namely the United Kingdom and France, who fought alongside the Ottoman Empire in the Crimean War against Russia. During the Congress of Paris on 30 March 1856, the Ottoman Empire was officially included among the European family of nations. Abdulmejid's biggest achievement was the announcement and application of the Tanzimat (reorganiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
