Guaíra Falls
Guairá Falls ( es, Saltos del Guairá, pt, Salto das Sete Quedas do Guaíra) were a series of immense waterfalls on the Paraná River along the border between Paraguay and Brazil. The falls ceased to exist in 1982 when they were inundated by the impoundment of the Itaipu Dam reservoir. While published figures vary, ranging from per second to per second, Guaíra's flow rate was among the greatest of any then-existing falls on Earth. The falls comprised 18 cataracts clustered in seven groups—hence their Portuguese name, ''Sete Quedas'' (Seven Falls)—near the Brazilian municipality of Guaíra, Paraná and Salto de Guairá, the easternmost city in Paraguay. The falls were located at a point where the Paraná River was forced through a narrow gorge. At the head of the falls, the river narrowed sharply from a width of about to . The total height of the falls was approximately , while the largest individual cataract was high. The roar of the plunging water could be heard from ...

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. ...

Simple Suspension Bridge
A simple suspension bridge (also rope bridge, swing bridge (in New Zealand), suspended bridge, hanging bridge and catenary bridge) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers. The cables follow a shallow downward catenary arc which moves in response to dynamic loads on the bridge deck. The arc of the deck and its large movement under load make such bridges unsuitable for vehicular traffic. Simple suspension bridges are restricted in their use to foot traffic. For safety, they are built with stout handrail cables, supported on short piers at each end, and running parallel to the load-bearing cables. Sometime these may be the primary load-bearing element, with the deck suspended below. Simple suspension bridges are considered the most efficient and sustainable design in rural regions, especially for river crossings that lie in non-floodplain topography such a ...

Waterfalls Of Paraguay
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples Of The Americas
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demonstration (people)
A political demonstration is an action by a mass group or collection of groups of people in favor of a political or other cause or people partaking in a protest against a cause of concern; it often consists of walking in a mass march formation and either beginning with or meeting at a designated endpoint, or rally, in order to hear speakers. It is different from mass meeting. Actions such as blockades and sit-ins may also be referred to as demonstrations. Demonstrations can be nonviolent or violent (usually referred to by participants as " militant"), or can begin as nonviolent and turn violent depending on the circumstances. Sometimes riot police or other forms of law enforcement become involved. In some cases, this may be in order to try to prevent the protest from taking place at all. In other cases, it may be to prevent clashes between rival groups, or to prevent a demonstration from spreading and turning into a riot. History The term has been in use since the mid-19th ...

Carlos Drummond De Andrade
Carlos Drummond de Andrade () (October 31, 1902 – August 17, 1987) was a Brazilian poet and writer, considered by some as the greatest Brazilian poet of all time. He has become something of a national cultural symbol in Brazil, where his widely influential poem "Canção Amiga" ("Friendly Song") has been featured on the 50- cruzado novo bill. Biography Drummond was born in Itabira, a mining village in Minas Gerais in the southeastern region of Brazil. His parents were farmers belonging to old Brazilian families of mainly Portuguese origin. He went to a school of pharmacy in Belo Horizonte, but never worked as a pharmacist after graduation, as he did not enjoy the career he chose. He worked as a civil servant for most of his life, eventually becoming director of the history for the National Historical and Artistic Heritage Service of Brazil. Though his earliest poems are formal and satirical, Drummond quickly adopted the new forms of Brazilian modernism that were evolving i ...
