Bodø Lighthouse
Nyholmen Lighthouse ( no, Nyholmen fyr, formerly called ''Bodø fyr'') is a coastal lighthouse in Bodø Municipality in Nordland county, Norway. It is located on the extreme southwestern tip of a small island (connected to the mainland by a causeway) in the northern part of the harbour for the Bodø (town), town of Bodø. The light sits atop a tall white, fiberglass tower. The light sits at an elevation of above sea level. It flashes white, red, or green light (depending on direction), Occulting light, occulting once every six seconds. History The original lighthouse was built in 1875 and it consisted of a tall octagonal cast iron tower attached to the front corner of a stone, white, -story keeper's house. That light was discontinued in 1907 when a new tower was built closer to the southwestern tip of the island. The new light was automated on the top of a concrete tower. The old lighthouse was transferred to the Society for the Preservation of Ancient Norwegian Monuments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nordland
Nordland (; smj, Nordlánnda, sma, Nordlaante, sme, Nordlánda, en, Northland) is a county in Norway in the Northern Norway region, the least populous of all 11 counties, bordering Troms og Finnmark in the north, Trøndelag in the south, Norrbotten County in Sweden to the east, Västerbotten County to the south-east, and the Atlantic Ocean (Norwegian Sea) to the west.

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Bodø
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In Nordland
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] |

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 ...

Society For The Preservation Of Ancient Norwegian Monuments
Society for the Preservation of Ancient Norwegian Monuments ( no, Fortidsminneforeningen) is an organization focused on conservation preservation in Norway. The Society was founded in 1844. The founders were painters, historians, art historians and archeologists, including J. C. Dahl and Joachim Frich. Nicolay Nicolaysen became chairman in 1851 and from 1860 was the association antiquarian. The purpose of the association is to protect and preserve buildings, churches and other forms of cultural heritage. It owns forty structures directly, including the stave churches at Borgund, Urnes, Hopperstad and Uvdal. The Society has 18 county branches and 37 local branches in the counties. The branch structure resembles the county structure of Norway, except that Oslo and Akershus are together, Møre and Romsdal is split into Sunnmøre, Nordmøre and Romsdal, and the town of Røros is a division of its own.

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 ...

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 ...

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, " ...
