Characidae
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being are the tetras, comprising the very similar genera ''Hemigrammus'' and ''Hyphessobrycon'', as well as a few related forms such as the cave and neon tetras. Fish of this family are important as food and also include popular aquarium fish species. These fish vary in length, though many are less than . One of the smallest species, ''Hyphessobrycon roseus'', grows to a maximum length of 1.9 cm. These fish inhabit a wide range and a variety of habitats. They originate in the Americas, ranging from southwestern Texas and Mexico through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetra
Terrestrial Trunked Radio (TETRA; formerly known as Trans-European Trunked Radio), a European standard for a trunked radio system, is a professional mobile radio and two-way transceiver specification. TETRA was specifically designed for use by government agencies, emergency services, (police forces, fire departments, ambulance) for public safety networks, rail transport staff for train radios, transport services and the military. TETRA is the European version of trunked radio, similar to Project 25. TETRA is a European Telecommunications Standards Institute (ETSI) standard, first version published 1995; it is mentioned by the European Radiocommunications Committee (ERC). Description TETRA uses time-division multiple access (TDMA) with four user channels on one radio carrier and 25 kHz spacing between carriers. Both point-to-point and point-to-multipoint transfer can be used. Digital data transmission is also included in the standard though at a low data rate. TETRA Mob ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon system ...

Maroni (river)
The Maroni or Marowijne (french: link=no, Maroni, nl, Marowijne, Sranan Tongo: ''Marwina-Liba'') is a river in South America that forms the border between French Guiana and Suriname. Course The Maroni runs through the Guianan moist forests ecoregion. It originates in the Tumuk Humak Mountains and forms the (disputed) border between France (region of French Guiana) and Suriname. In its upper reaches, it is also known as the Lawa, and close to its source it is known as the Litani. The total length of Litani, Lawa and Maroni is . There are two nature preserves located in the estuary region on the Surinamese side of the river, near the village of Galibi. They provide protection for the birds and the leatherback sea turtles that hatch there. Territorial dispute In 1860, the question was posed from the French side, which of the two tributary rivers was the headwater, and thus the border. A joint French-Dutch commission was appointed to review the issue. The Dutch side of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesica Piscis
The vesica piscis is a type of lens, a mathematical shape formed by the intersection of two disks with the same radius, intersecting in such a way that the center of each disk lies on the perimeter of the other. In Latin, "vesica piscis" literally means "bladder of a fish", reflecting the shape's resemblance to the conjoined dual air bladders ("swim bladder") found in most fish. In Italian, the shape's name is ''mandorla'' ("almond"). This figure appears in the first proposition of Euclid's ''Elements'', where it forms the first step in constructing an equilateral triangle using a compass and straightedge. The triangle has as its vertices the two disk centers and one of the two sharp corners of the vesica piscis. Mathematical description Mathematically, the vesica piscis is a special case of a lens, the shape formed by the intersection of two disks. The mathematical ratio of the height of the vesica piscis to the width across its center is the square root of 3, or 1.732050 ...
