Río Grande De Santiago
The Río Grande de Santiago, or Santiago River, is a river in western Mexico. It flows westwards from Lake Chapala via Ocotlán through the states of Jalisco and Nayarit to empty into the Pacific Ocean. It one of the longest rivers in Mexico, measuring up long. Geography The river begins at Lake Chapala via Ocotlán and continues roughly north-west through the Sierra Madre Occidental, receiving the Verde, Juchipila, Bolaños, Huaynamota, Mololoa, and other tributaries. The Río Grande de Santiago descends over 1700 meters between Lake Chapala and the sea. Downstream from Lake Chapala the river and its major tributaries have carved deep narrow canyons, or barrancas, which can be 600 meters lower than the surrounding plateau. The lower elevation and year-round moisture in the canyon bottoms sustain forests, which include many coastal tropical species not found on the plateaus. The Barranca de Oblatos or Barranca de Huentitán is a protected area popular with residents of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nayarit
Nayarit (), officially the Free and Sovereign State of Nayarit ( es, Estado Libre y Soberano de Nayarit), is one of the 31 states that, along with Mexico City, comprise the Federal Entities of Mexico. It is divided in 20 municipalities and its capital city is Tepic. It is bordered by the states of Sinaloa to the northwest, Durango to the north, Zacatecas to the northeast and Jalisco to the south. To the west, Nayarit has a significant share of coastline on the Pacific Ocean, including the islands of Marías and Marietas. The beaches of San Blas and the so-called "Riviera Nayarit" are popular with tourists. Besides tourism, the economy of the state is based mainly on agriculture and fishing. It is also one of two states where the tarantula species ''Brachypelma klaasi'' is found, the other being Jalisco. Home to Uto-Aztecan indigenous peoples such as the Huichol and Cora, the region was exposed to the ''conquistadores'', Hernán Cortés and Nuño de Guzmán, in the 16t ...

Toluene
Toluene (), also known as toluol (), is a substituted aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent. As the solvent in some types of paint thinner, permanent markers, contact cement and certain types of glue, toluene is sometimes used as a recreational inhalant and has the potential of causing severe neurological harm. History The compound was first isolated in 1837 through a distillation of pine oil by the Polish chemist Filip Walter, who named it ''rétinnaphte''. In 1841, French chemist Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree ''Myroxylon balsamum''), which Deville recognized as similar to Wa ...

Phenol
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol ...

Phthalates
Phthalates (, ), or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC). Note that while phthalates are usually plasticizers, not all plasticizers are phthalates. The two terms are specific and unique and cannot be used interchangeably. Lower-molecular-weight phthalates, those derived from C3-C6 alcohols, are being gradually replaced in many products in the United States, Canada, and European Union over health concerns. They are being replaced by high-molecular-weight phthalates (those with more than six carbons in their backbone, which gives them increased permanency and durability), as well as alternative plasticizers not based on phthalic anhydride. In 2010, the market was still dominated by high-phthalate plasticizers; however, due to legal provisions and growing environmental aw ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lerma River
The Lerma River ( es, Río Lerma) is Mexico's second longest river. It is a river in west-central Mexico that begins in Mexican Plateau at an altitude over above sea level, and ends where it empties into Lake Chapala, Mexico's largest lake, near Guadalajara, Jalisco. Lake Chapala is the starting point of Río Grande de Santiago, which some treat as a continuation of the Lerma River. In combination, the two are often called the Lerma Santiago River ( es, Río Lerma Santiago). The Lerma River is notorious for its pollution, but the water quality has demonstrated considerable improvement in recent years due mostly to government environmental programs and through massive upgrading projects of sanitation works. Course The Lerma River originates from the Lerma lagoons near Almoloya del Río, on a plateau more than above sea level, and southeast of Toluca. The lagoons receive their water from springs rising from basaltic volcanics that flow down from Monte de Las Cruces. These are lo ...

Aguamilpa Dam
The Aguamilpa Dam is an embankment dam on the Río Grande de Santiago in the Mexican state of Nayarit, northeast of Tepic. The primary purpose of the dam is hydroelectric power generation and it supplies a 960 MW power station with water. Construction on the dam began in 1989 and it was completed in 1993 while the power station became operational in 1994.
