Grusonia
''Grusonia'' is a genus of opuntioid cacti (family Cactaceae), originating from the North American Deserts in Southwest United States and northern Mexico, including Baja California. Authors differ on precise boundaries of the genus, which has been included in '' Cylindropuntia''. ''Corynopuntia'', also known as club chollas (or "perritos" in Mexico), is now a synonym, with the genus originally being described by Knuth in 1935. Molecular phylogenetic studies suggest that it should be included in ''Grusonia'', a view accepted by Plants of the World Online . Etymology The name ''Corynopuntia'' comes from the Greek ''coryne'', meaning ‘club’, and refers to the club-shaped branch segments, so "club opuntia", club cholla. Description These opuntioid plants grow in low opuntioid cushions, consisting of rather ovoid or slightly clavate segments, from 1 up to 25 cm long, tuberculate, not ribbed, glabrous. Spines are strong, very prickly and dangerous, covered on their margi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echinocactus Grusonii
''Echinocactus grusonii'' or ''Kroenleinia grusonii'', popularly known as the golden barrel cactus, golden ball or mother-in-law's cushion, is a species of barrel cactus which is endemic to east-central Mexico. It is rare and endangered in the wild, where it is found near Mesa de León in the state of Querétaro, and in the state of Hidalgo. The population was critically reduced in the 1990s, by the creation of the Zimapán Dam and reservoir in Hidalgo. The cactus grows in volcanic rock on slopes, at altitudes around . Taxonomy ''Echinocactus grusonii'' belongs to the small genus ''Echinocactus'', which together with the related genus ''Ferocactus'', are commonly referred to as barrel cacti. The species was first described by German plantsman Heinrich Hildmann in 1891. While sometimes referred to as golden ball, this species is not to be confused with '' Notocactus leninghausii'' which have fuzzy, harmless spines and are native to Brazil and Paraguay.

Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...

Fahrpanzer
The Fahrpanzer was a mobile artillery piece made prior to World War I in Germany, implemented in several German fortifications from 1890 onwards and exported to several foreign military powers prior to the outbreak of hostilities. Specifications Beginning in 1878 the German industrialist Hermann Gruson's company located in Magdeburg, Germany specialized in the design and construction of armored gun turrets for fortifications. In 1892 Gruson's company merged with Krupp which greatly increased production capacity and the market for their designs. Gruson works turrets could be found in fortifications in Austria-Hungary, Belgium, Denmark, Germany, and Italy. One of his company's products was the Fahrpanzer, which was a type of mobile armored pillbox. As designed, the Fahrpanzer was mounted on narrow gauge railroad trucks and was wheeled along military gauge tracks to its battle station. When not in use it would be pushed into a protective bunker to avoid damage during heavy bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Spezia
La Spezia (, or , ; in the local Spezzino dialect) is the capital city of the province of La Spezia and is located at the head of the Gulf of La Spezia in the southern part of the Liguria region of Italy. La Spezia is the second largest city in the Liguria region, after Genoa. Located roughly midway between Genoa and Pisa, on the Ligurian Sea, it is one of the main Italian military and commercial harbours and a major Italian Navy base. A popular seaside resort, it is also a significant railway junction, and is notable for its museums, for the Palio del Golfo rowing race, and for railway and boat links with the Cinque Terre. History La Spezia and its province have been settled since prehistoric times. In ancient Rome, Roman times the most important centre was Luni (Italy), Luni, not far from Sarzana. As the capital of the short-lived Niccolò Fieschi Signoria in the period between 1256 and 1273, La Spezia was inevitably linked with Genoese vicissitudes. After the fall of t ...

Weser
The Weser () is a river of Lower Saxony in north-west Germany. It begins at Hannoversch Münden through the confluence of the Werra and Fulda. It passes through the Hanseatic city of Bremen. Its mouth is further north against the ports of Bremerhaven and Nordenham. The latter is on the Butjadingen Peninsula. It then merges into the North Sea via two highly saline, estuarine mouths. It connects to the canal network running east-west across the North German Plain. The river, when combined with the Werra (a dialectal form of "Weser"), is long and thus, the longest river entirely situated within Germany (the Main, however, is the longest if the Weser and Werra are not combined). The Weser itself is long. The Werra rises in Thuringia, the German state south of the main projection (tongue) of Lower Saxony. Etymology "Weser" and "Werra" are the same words in different dialects. The difference reflects the old linguistic border between Central and Low German, passing through H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetite
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak. Small grains of magnetite are very common in igneous and metamorphic rocks. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ''ferrous-ferric oxide''. Properties In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments ...
