Ødegården Verk
Ødegården Verk (''Ødegården Mines'', ), alternate names ''Ødegården Apatittgruver'' and ''Bamble Apatittgruver'', was a series of primarily apatite shaft mines and quarries located in the Bamble municipality of Norway. At its peak, Ødegården Verk was one of the largest apatite mines in the country, mining up to 10,000 metric tons of the mineral per year, and some sources estimate its peak operating workforce at over 800 men. The site of Ødegården Verk is about 1 km south of the E18, turning off on the road Feset between Kragerø and Brevik. Apatite and other minerals were originally transported by horse and cart by local farmers from the site to one of three local ports for shipment: Åby to the east in Åbyfjorden, Brevikstranda on Brevikstrandfjorden to the southeast, or a port to the south in Isnes, just west of the modern port town Valle. Later, a funicular was built between the mines and the docks at Isnes, bringing passengers as well as rocks and suppl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boater
__NOTOC__ A boater (also straw boater, basher, skimmer, The English Panama, cady, katie, canotier, somer, or sennit hat) is a semi-formal summer hat for men, which was popularised in the late 19th century and early 20th century. It is normally made of stiff sennit straw and has a stiff flat crown and brim, typically with a solid or striped grosgrain ribbon around the crown. Boaters were derived from the canotier straw hat worn traditionally by gondoliers in the city of Venice. The Venetian canotier has a ribbon that hangs freely off the back, and they are frequently edged with a matching color ribbon. Because of this, boaters were identified with boating or sailing, hence the name. Boaters were also identified more with sporting events and universities as well. They were also worn by women, often with hatpins to keep them in place. Nowadays they are rarely seen except at sailing or rowing events, period-related theatrical and musical performances (e.g. barbershop music) or as ...

Brevik, Norway
Brevik () is a List of towns and cities in Norway, town in Porsgrunn Municipality in Telemark county, Norway. The town is located where the Eidangerfjorden and Frierfjorden join together to form the Breviksfjorden. Brevik is regarded as one of the best preserved towns from the sailing ship era. The town is located on the far end of Eidanger peninsula (:no:Eidangerhalvøya, Eidangerhalvøya), and was a former export centre for ice and timber. The last shipment of wood to the United Kingdom was around 1960. Brevik is located about to the south of the Porsgrunn (town), town of Porsgrunn in a very large urban area. Brevik has an estimated population of 2,100 in the year 2020. It is considered part of the Porsgrunn/Skien metropolitan area by Statistics Norway, so Brevik's population is not tracked separately. Brevik has significant industry, including cement production (Norcem, formerly Dalen Portland Cementfabrik, which is Norway's largest cement factory), workshop industry, food in ...

Fertilizer
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. fish processing waste, or bloodmeal from animal slaughter). However, starting in the 19th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphorus
Phosphorus is a chemical element; it has Chemical symbol, symbol P and atomic number 15. All elemental forms of phosphorus are highly Reactivity (chemistry), reactive and are therefore never found in nature. They can nevertheless be prepared artificially, the two most common allotropes being white phosphorus and red phosphorus. With as its only stable isotope, phosphorus has an occurrence in Earth's crust of about 0.1%, generally as phosphate rock. A member of the pnictogen family, phosphorus readily forms a wide variety of organic compound, organic and inorganic compound, inorganic compounds, with as its main oxidation states +5, +3 and −3. The isolation of white phosphorus in 1669 by Hennig Brand marked the scientific community's first discovery since Antiquity of an element. The name phosphorus is a reference to the Phosphorus (morning star), god of the Morning star in Greek mythology, inspired by the faint glow of white phosphorus when exposed to oxygen. This property is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tellef Dahll
Tellef Dahll (10 April 1825, in Kragerø – 17 June 1893, in Morgedal) was a Norwegian mineralogist and geologist. Life After graduating in minearology from the University of Christiania in 1846, Dahll worked for private mining companies. He found coal on the island of Andøya, iron ore at Bjørnevatn and in 1867 Dahll discovered gold from the Tana and Anarjohka Anarjohka (, or ''Anarjohka'', , ) is a tributary of Tana River (Norway), Tana River. It is about long, with a drainage area of about . In 1879 Dahll collected samples of nickel arsenide and gersdorffite on the island of Oterøya in his birthplace Kragerø. Dahll found out that the rocks contained previously unknown element which he named Norwegium. The phosphate mineral dahllite (hydroxylapatite) is named after Tellef Dahll and his brother, the mineralogist Johann Dahll. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroxylapatite
Hydroxyapatite ( IMA name: hydroxylapatite) (Hap, HAp, or HA) is a naturally occurring mineral form of calcium apatite with the formula , often written to denote that the crystal unit cell comprises two entities. It is the hydroxyl endmember of the complex apatite group. The ion can be replaced by fluoride or chloride, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system. Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxyapatite, known as bone mineral. Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors, as well as calcifications within the pineal gland (and ot ...

Carbonate
A carbonate is a salt of carbonic acid, (), characterized by the presence of the carbonate ion, a polyatomic ion with the formula . The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group . The term is also used as a verb, to describe carbonation: the process of raising the concentrations of carbonate and bicarbonate ions in water to produce carbonated water and other carbonated beverageseither by the addition of carbon dioxide gas under pressure or by dissolving carbonate or bicarbonate salts into the water. In geology and mineralogy, the term "carbonate" can refer both to carbonate minerals and carbonate rock (which is made of chiefly carbonate minerals), and both are dominated by the carbonate ion, . Carbonate minerals are extremely varied and ubiquitous in chemically precipitated sedimentary rock. The most common are calcite or calcium carbonate, , the chief constituent of limestone (as well as the main component of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waldemar Christofer Brøgger (geologist)
Waldemar Christofer Brøgger FRSE (10 November 185117 February 1940) was a Norwegian geologist and mineralogist. His research on Permian igneous rocks (286 to 245 million years ago) of the Oslo district greatly advanced petrologic theory on the formation of rocks. Biography He was born in Christiania (now Oslo), Norway. He was the son of Anton Wilhelm Brøgger (1820–1882) and Oline (“Lina”) Marie Bjerring (1826–1905). He attended Oslo Cathedral School and graduated in 1870. He studied science and zoology under Theodor Kjerulf at University of Christiania (now University of Oslo). He was Cand. filos. (1870) and delivered his dissertation in 1875. Brøgger was then immediately employed in the Norwegian Geological Survey as an assistant. In the winter of 1875–76, he made a study trip together with fellow student Hans Reusch (1852–1922) to Corsica and Elba. The two jointly published an illustrated work, ''Jættegryder ved Christiania'' (Copenhagen. 1874) wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapolite
The scapolites (, "rod", and , "stone") are a group of rock-forming silicate minerals composed of aluminium, calcium, and sodium silicate with chlorine, carbonate and sulfate. The two endmembers are meionite () and marialite (). Silvialite is also a recognized member of the group. Properties The group is an isomorphous mixture of the meionite and marialite endmembers. The tetragonal crystals are hemihedral with parallel faces (like scheelite), and at times of considerable size. They are distinct and usually have the form of square columns, some cleavages parallel to the prism-faces. Crystals are usually white or greyish-white and opaque, though meionite is found as colorless glassy crystals in the ejected limestone blocks of Monte Somma, Vesuvius. The hardness is 5–6, and the specific gravity varies with the chemical composition between 2.7 (meionite) and 2.5 (marialite). The scapolites are especially liable to alteration by weathering processes, with the developmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rutile
Rutile is an oxide mineral composed of titanium dioxide (TiO2), the most common natural form of TiO2. Rarer polymorphs of TiO2 are known, including anatase, akaogiite, and brookite. Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high dispersion. Owing to these properties, it is useful for the manufacture of certain optical elements, especially polarization optics, for longer visible and infrared wavelengths up to about 4.5 micrometres. Natural rutile may contain up to 10% iron and significant amounts of niobium and tantalum. Rutile derives its name from the Latin ('red'), in reference to the deep red color observed in some specimens when viewed by transmitted light. Rutile was first described in 1803 by Abraham Gottlob Werner using specimens obtained in Horcajuelo de la Sierra, Madrid (Spain), which is consequently the type locality. Occurrence Rutile is a comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Funicular
A funicular ( ) is a type of cable railway system that connects points along a railway track laid on a steep grade (slope), slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
