Rumeli Feneri
__NOTOC__ Rumeli Feneri, also Türkeli Feneri, a historical lighthouse still in use, is located on the European side of the Bosporus Strait's Black Sea entrance in Istanbul. Etymology Rumeli (or Rumelia) is a former name for the Ottoman territories west of the Bosporus Strait. The lighthouse is named for it because of Anadolu Feneri, a lighthouse parallel to it on the eastern side of the Bosporus Strait. Overview Rumeli Feneri is across from the Anadolu Feneri lighthouse, which is on the Anatolian side of the strait at a distance of . In the Greek myth of Jason and the Golden Fleece, the two islets these lighthouses were built were called the Symplegades. They became a gang, destroying any ship which passed between them. A line connecting the two lighthouses marks the northern boundary of the Port of Istanbul. The lighthouse town is Rumelifeneri, which today is a fishermen's village in Sarıyer district. The lighthouse was built by the French in order to provide safe navigat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarıyer
Sarıyer () is the northernmost district of Istanbul, Turkey, on the European side of the city. It consists of the neighbourhoods of Rumelifeneri, Tarabya, Yeniköy, İstinye, Emirgan and Rumelihisarı. Sarıyer also administers the Black Sea coast to the west of the mouth of the Bosphorus, including the neighbourhood of Kilyos. It borders Eyüp to the northwest, Beşiktaş to the south and Kağıthane to the west. Sarıyer has a population of approximately 260,000. The mayor is Şükrü Genç of the Republican People's Party (CHP). In 1930, some parts of the region of Beyoğlu and Çatalca were incorporated into Sarıyer, which also became the district centre. The district's boundaries shrunk after the neighbourhood of Kemerburgaz was given to the Eyüp district in 1936 and when the villages of Maslak and Ayazağa were given to Şişli district in 1954. The present boundaries of Sarıyer were created after incorporating the neighbourhoods of Maslak, Ayazağa and Huzur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Michiga ...

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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bosphorus
The Bosporus Strait (; grc, Βόσπορος ; tr, İstanbul Boğazı 'Istanbul strait', colloquially ''Boğaz'') or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul in northwestern Turkey. It forms part of the continental boundary between Asia and Europe, and divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation. Most of the shores of the Bosporus Strait, except for the area to the north, are heavily settled, with the city of Istanbul's metropolitan population of 17 million inhabitants extending inland from both banks. The Bosporus Strait and the Dardanelles Strait at the opposite end of the Sea of Marmara are together known as the Turkish Straits. Sections of the shore of the Bosporus in Istanbul have been reinforced with concrete or rubble and those sections of the Strait prone to deposition are periodically dredged. Name The name of the ...

Tourist Attractions In Istanbul
Tourism is travel for pleasure or business; also the theory and practice of touring (other), touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tour (other), 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 tourism, domestic (within the traveller's own country) or International tourism, 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 t ...

Waliullah
A wali (''wali'' ar, وَلِيّ, '; plural , '), the Arabic word which has been variously translated "master", "authority", "custodian", "protector", is most commonly used by Muslims to indicate an Islamic saint, otherwise referred to by the more literal "friend of God".John Renard, ''Friends of God: Islamic Images of Piety, Commitment, and Servanthood'' (Berkeley: University of California Press, 2008); John Renard, ''Tales of God Friends: Islamic Hagiography in Translation'' (Berkeley: University of California Press, 2009), passim. When the Arabic definite article () is added, it refers to one of the names of God in Islam, Allah – (), meaning "the Helper, Friend". In the traditional Islamic understanding of saints, the saint is portrayed as someone "marked by pecialdivine favor ... [and] holiness", and who is specifically "chosen by God and endowed with exceptional gifts, such as the ability to work Miracle worker, miracles".Radtke, B., "Saint", in: ''Encyclopaedia ...

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for re ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

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 o ...
