Buholmråsa Lighthouse
The Buholmråsa Lighthouse ( no, Buholmråsa fyr) is a coastal lighthouse in the municipality of Osen in Trøndelag county, Norway. The lighthouse is located in the Svesfjorden on the small island ''Sønnaholmen'' about northwest of the village of Seter, Osen, Seter. It was built in 1917 and automated in 1994. The Kya Lighthouse lies on a small island in the open ocean about to the northwest of Buholmråsa Lighthouse. During World War II, air raids damaged some of the buildings at this station. The tall, round, cast iron lighthouse is red with one white stripe and it can be seen for up to . The light sits on top at an elevation of above sea level. The 140,400-candela light emits a white, red, or green light (depending on direction), Occulting Light, occulting once every six seconds. The lighthouse also broadcasts a racon signal that is a morse code letter B (-•••). See also *Lighthouses in Norway *List of lighthouses in Norway References External links Norsk Fyr ...

Coastal Lighthouse
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] |
Occulting Light
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 red, " ...

Lighthouses In Norway
The coast of Norway is 100,915 km long and there have been a total of 212 lighthouses along it, but no more than 154 have ever been operational at the same time. The first, Lindesnes Lighthouse, opened in 1655; the newest Lighthouse, Anda, was finished in 1932. The first Lighthouses were private operations, but in 1821 the government made the Channel and Harbor Inspector responsible for Lighthouses in Norway. A dedicated Lighthouse Administration was set up in 1841. The Lighthouses are today mostly automated and since 1974, run by the Norwegian Coastal Administration. Two lightvessels had been operated along the Norwegian coast. "Enigheden" off Ålesund from 1856 vas replaced with Lepsøyrev Lighthouse in 1879, and "Ildjernsflu" moored off Nesodden from 1914 until it was scrapped in 1968. This list, while not complete, is sorted by location along the shipping lane from the border with Sweden in the south to Russia in the northeast. The Norwegian Coastal Administration main ...

Kunnskapsforlaget
Kunnskapsforlaget () is a Norwegian publishing company based in Oslo. Kunnskapsforlaget was established in 1975, as a partnership between H. Aschehoug & Co. (W. Nygaard) and Gyldendal Norsk Forlag. The purpose was to co-operate on publishing encyclopaedias and dictionaries. The first volume of Store norske leksikon (SNL) was published in 1978. A total of four editions was published (the last one in 2004), before the online version was transferred to Institusjonen Fritt Ord og Sparebankstiftelsen DnB in 2011. Kunnskapsforlaget is the largest dictionary publisher in Norway. They publish both printed books, and digital dictionaries that are available through the online service Ordnett (launched in 2004). Their main languages are English and Norwegian, but they also have dictionaries in 21 other languages. In September 2018, Gyldendal Norsk Forlag became the single owner of the company. As of 2018, the publisher has eight full-time employees. The CEO is Thomas Nygaard Thomas m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Store Norske Leksikon
The ''Great Norwegian Encyclopedia'' ( no, Store Norske Leksikon, abbreviated ''SNL''), is a Norwegian-language online encyclopedia. The online encyclopedia is among the most-read Norwegian published sites, with more than two million unique visitors per month. Paper editions 1978–2007 The ''SNL'' was created in 1978, when the two publishing houses Aschehoug and Gyldendal merged their encyclopedias and created the company Kunnskapsforlaget. Up until 1978 the two publishing houses of Aschehoug and Gyldendal, Norway's two largest, had published ' and ', respectively. The respective first editions were published in 1907–1913 (Aschehoug) and 1933–1934 (Gyldendal). The slump in sales for paper-based encyclopedias around the turn of the 21st century hit Kunnskapsforlaget hard, but a fourth edition of the paper encyclopedia was secured by a grant of ten million Norwegian kroner from the foundation Fritt Ord in 2003. The fourth edition consisted of 16 volumes, a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Racon
Radar beacon (short: racon) is – according to ''article 1.103'' of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) – defined as "A transmitter-receiver associated with a fixed navigational mark which, when triggered by a radar, automatically returns a distinctive signal which can appear on the display of the triggering radar, providing range, bearing and identification information." Each ''station'' (transmitter-receiver, transceiver or transponder) shall be classified by the ''service'' in which it operates permanently or temporarily. Principle of operation When a racon receives a radar pulse, it responds with a signal on the same frequency which puts an image on the radar display. This takes the form of a short line of dots and dashes forming a Morse character radiating away from the location of the beacon on the normal plan position indicator radar display. The length of the line usually corresponds to the equivalent of a few nautical miles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

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 applications and are ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
