Tafelberg (Curaçao)
Tafelberg (''Table Mountain'')] is a large flat-topped hill in Curaçao, an island state in the Dutch Caribbean. mesa is in southeastern Curaçao, near the Santa Barbara beach. It is high, making it only the fourth-highest point on Curaçao behind the Christoffelberg and two intermediate peaks, all in the volcanic northwest of the island. It is formed mostly of the Quaternary limestone that forms the south-east of Curaçao, although there are also commercially-significant phosphate and calcareous sand deposits. Fossils of Pleistocene giant tortoises, Chelonoidis, of an estimated carapace length have been found in fill deposits. The vegetation of the area is sparse, owing to the endemic lack of water on Curaçao. Comparisons of grazed and inaccessibly ungrazed areas show that the natural vegetation was predominantly of the bromeliad '' Tillandsia flexuosa'', but that this could not tolerate grazing and since the introduction of livestock by humans, primarily goats, has larg ...

Curaçao
Curaçao, officially the Country of Curaçao, is a constituent island country within the Kingdom of the Netherlands, located in the southern Caribbean Sea (specifically the Dutch Caribbean region), about north of Venezuela. Curaçao includes the main island of Curaçao and the much smaller, uninhabited island of Klein Curaçao ("Little Curaçao"). Curaçao has a population of 158,665 (January 2019 estimate), with an area of ; its capital is Willemstad. Together with Aruba and Bonaire, Curaçao forms the ABC islands (Leeward Antilles), ABC islands. Collectively, Curaçao, Aruba, and other Dutch islands in the Caribbean are often called the Dutch Caribbean. It is the largest of the ABC islands in terms of area, as well as in terms of population, and is the largest in the Dutch Caribbean. The island's name "Curaçao" may originate from the indigenous autonym of its people; this idea is supported by early Spanish accounts referring to the inhabitants as Indios Curaçaos. Curaç ...

Guano
Guano (Spanish from ) is the accumulated excrement of seabirds or bats. Guano is a highly effective fertiliser due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern Intensive farming, input-intensive farming. The demand for guano spurred the human colonisation of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, Fungus, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social And Economic Studies
Social organisms, including human(s), live collectively in interacting populations. This interaction is considered social whether they are aware of it or not, and whether the exchange is voluntary or not. Etymology The word "social" derives from the Latin word ''socii'' ("allies"). It is particularly derived from the Italian ''Socii'' states, historical allies of the Roman Republic (although they rebelled against Rome in the Social War of 91–87 BC). Social theorists In the view of Karl Marx,Morrison, Ken. ''Marx, Durkheim, Weber. Formations of modern social thought'' human beings are intrinsically, necessarily and by definition social beings who, beyond being "gregarious creatures", cannot survive and meet their needs other than through social co-operation and association. Their social characteristics are therefore to a large extent an objectively given fact, stamped on them from birth and affirmed by socialization processes; and, according to Marx, in producing and reproduci ...

Copeia
''Ichthyology & Herpetology'' (formerly ''Copeia'') is a quarterly peer-reviewed scientific journal covering research in ichthyology and herpetology that was originally named after Edward Drinker Cope, a prominent American researcher in these fields. It is the official journal of the American Society of Ichthyologists and Herpetologists. According to the ''Journal Citation Reports'', ''Copeia'' has a 2021 impact factor of 1.857, ranking it 65th out of 176 journals in the category "Zoology". History On December 27, 1913, John Treadwell Nichols published the first issue of ''Copeia''. This issue consisted of a single piece of paper folded to form four pages of information with five articles. The cover of the pamphlet bore the inscription: "Published by the contributors to advance the science of coldblooded vertebrates." In 2020, the American Society of Ichthyologists and Herpetologists voted to rename the journal, ''Ichthyology & Herpetology''. Name change The journal ...

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime- or calcium silicate-based, and are either hydraulic or less commonly non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble. This allows setting in wet conditions or u ...

Nieuwpoort, Curaçao
Spaanse Water is a town on the island of Curaçao. It contains the tourist resort ''Nieuwpoort'', the village of ''Santa Barbara'', and the Tafelberg. Spaanse Water is a natural harbour and lagoon located to the east of Willemstad. The lagoon contains several bays and little islands. History Spaanse Water was a strategically important location. In 1703, Fort Beekenburg was constructed on the Caracas Bay to protect the natural harbour and the back route to Willemstad. The fort was built by Nicolaas van Beek who at the time served as Director of Curaçao. It has been attacked several times by the French, English, and pirates, but has never been conquered. The fort used to be owned by Royal Dutch Shell, but since 2005, it is publicly accessible. Santa Barbara is a plantation founded in 1662, and was one of the oldest and largest plantations on the island. It was not very profitable, and sold in January 1875. The plantation was subsequently resold to John Godden in May 1875 who st ... [...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] |
Aruba
Aruba, officially the Country of Aruba, is a constituent island country within the Kingdom of the Netherlands, in the southern Caribbean Sea north of the Venezuelan peninsula of Paraguaná Peninsula, Paraguaná and northwest of Curaçao. In 1986, Aruba became a constituent country within the Kingdom of the Netherlands and acquired the formal name the Country of Aruba. Aruba has an area of . Aruba measures in length from its northwestern to its southeastern end and is across at its widest point. Aruba is geologically located in South America, South-America, lying on the South-American continental shelf. Alongside Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands (Leeward Antilles), ABC islands. The Dutch Caribbean encompasses the ABC islands along with the other three substantial islands, the SSS islands. In contrast to much of the Caribbean, which experiences humid tropical climates, Aruba has a dry climate with an arid Deserts and xeric shrublands, xer ...
