One Fathom Bank
The One Fathom Bank Lighthouse ( ms, Rumah Api One Fathom Bank or ) refers to two offshore lighthouses in the Strait of Malacca, specifically, on a shoal within Malaysian waters, dubbed One Fathom Bank (''Permatang Sedepa''), off the coast of the state of Selangor. The One Fathom Bank station was originally served by a lightship stationed in 1852 before a permanent screw-pile lighthouse was built in 1874; the lighthouse has since been replaced twice over the course of its service, in 1907 with a concrete pile lighthouse, and in 1999 when a larger modern counterpart was built parallel to the 1907 lighthouse, superseding its predecessor's duties. The lighthouses have since been referred to as the "old" One Fathom Bank Lighthouse and the "new" One Fathom Bank Lighthouse. Due to being well out to sea, both lighthouses are only accessible by boat. While both sites of the lighthouses are open, their towers remain off-limits.

Pile Lighthouse
A pile lighthouse is a type of lighthouse found in Australia and the United States. In the United States they are found primarily in Florida, including on open reefs adjacent to the Florida Keys. The pile lighthouses on the reefs in Florida are tall skeletal towers, with living and working quarters set high above the reach of storm waves. Some of the lights were converted screw-pile lighthouses, while others were built on piles driven directly into the sea bed.

Lightvessel
A lightvessel, or lightship, is a ship that acts as a lighthouse. They are used in waters that are too deep or otherwise unsuitable for lighthouse construction. Although some records exist of fire beacons being placed on ships in Roman times, the first modern lightvessel was off the Nore sandbank at the mouth of the River Thames in England, placed there by its inventor Robert Hamblin in 1734. The type has become largely obsolete; lighthouses replaced some stations as the construction techniques for lighthouses advanced, while large, automated buoys replaced others. Construction A crucial element of lightvessel design is the mounting of a light on a sufficiently tall mast. Initially, it consisted of oil lamps that could be run up the mast and lowered for servicing. Later vessels carried fixed lamps which were serviced in place. Fresnel lenses were used as they became available, and many vessels housed them in small versions of the lanterns used in lighthouses. Some lightshi ...

Lighthouses Completed In 1853
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] |
List Of Lighthouses In Malaysia
Malaysia is a country largely surrounded by large bodies of water, most notably by the Strait of Malacca and the South China Sea, that have been used extensively for maritime transport as early as the 15th century. Numerous lighthouses were erected during present-day Malaysia's rule by the Portuguese Empire, the Dutch Empire and the British Empire (which oversaw the greatest number of new lighthouses built), and, later, the government of Malaysia, to provide navigation in and out of ports or through dangerous seas. Many of these lighthouses are situated on small islands and headlands. The following lists lighthouses situated within the borders of Malaysia. Peninsular Malaysia East coast Lighthouses situated on the east coast of Peninsular Malaysia are frequently used for navigation at the South China Sea, as well as beacons into minor ports along the coast. * Bukit Puteri Lighthouse, Bukit Puteri, Terengganu * Pantai Senok Lighthouse (Pengkalan Daty Lighthouse), Pantai Sen ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confers rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). A balance of useful features, including temperature resistance, impact resistance and ...

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applicatio ...

Octagon
In geometry, an octagon (from the Greek ὀκτάγωνον ''oktágōnon'', "eight angles") is an eight-sided polygon or 8-gon. A ''regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties of the general octagon The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilatera ...

Malaysian Ringgit
The Malaysian ringgit (; plural: ringgit; symbol: RM; currency code: MYR; Malay name: ''Ringgit Malaysia''; formerly the Malaysian dollar) is the currency of Malaysia. It is divided into 100 ''sen'' (formerly ''cents''). The ringgit is issued by the Central Bank of Malaysia. Etymology The word ''ringgit'' is an obsolete term for "jagged" in the Malay language. The word was originally used to refer to the serrated edges. The first European coins to circulate widely in the region were Spanish " pieces of eight" or "cob", their crude appearance resembling stones, hence the word jagged. The availability and circulation of this Spanish currency were due to the Spanish controlling nearby Philippines. An early printed source, the ''Dictionary of the Malayan Language'' from 1812 had already referred to the ringgit as a unit of money. In modern usage, ''ringgit'' is used almost solely for the currency. Due to the common heritage of the three modern currencies, the Singapore doll ...

Port Klang
Port Klang ( ms, Pelabuhan Klang) is a town and the main gateway by sea into Malaysia. Known during colonial times as Port Swettenham ( ms, Pelabuhan Swettenham) but renamed Port Klang in July 1972, it is the largest port in the country. It is located about southwest of the town of Klang, and southwest of Kuala Lumpur. Located in the District of Klang, it was the 11th busiest container port (2012) in the world. It was also the 12th busiest port in by volume (million TEU) in 2018 and the top location of aluminium stock for LME, the top metal exchange in the world. History Klang was formerly the terminus of the government railway and the port of the State. In 1880, the state capital of Selangor was moved from Klang to the more strategically advantageous Kuala Lumpur. Rapid development at the new administrative centre in the late 1800s attracted businessmen and job seekers alike from Klang. At this time the only methods of transport between Klang and Kuala Lumpur were by hor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Pound
Sterling (abbreviation: stg; Other spelling styles, such as STG and Stg, are also seen. ISO code: GBP) is the currency of the United Kingdom and nine of its associated territories. The pound ( sign: £) is the main unit of sterling, and the word "pound" is also used to refer to the British currency generally, often qualified in international contexts as the British pound or the pound sterling. Sterling is the world's oldest currency that is still in use and that has been in continuous use since its inception. It is currently the fourth most-traded currency in the foreign exchange market, after the United States dollar, the euro, and the Japanese yen. Together with those three currencies and Renminbi, it forms the basket of currencies which calculate the value of IMF special drawing rights. As of mid-2021, sterling is also the fourth most-held reserve currency in global reserves. The Bank of England is the central bank for sterling, issuing its own banknotes, and reg ...
