Metallurgy In Pre-Columbian Mesoamerica
The emergence of metallurgy in pre-Columbian Mesoamerica occurred relatively late in the region's history, with distinctive works of metal apparent in West Mexico by roughly 800 CE, and perhaps as early as 600 CE. Metallurgical techniques likely diffused northward from regions in Central or South America via maritime trade routes; recipients of these metallurgical technologies apparently exploited a wide range of material, including alloys of copper-silver, copper-arsenic, copper-tin and copper-arsenic-tin. Metal items crafted throughout Mesoamerica may be broken into three classes: utilitarian objects, objects used for individual ornamentation, and ceremonial/ritual objects. The latter two categories comprise the bulk of distinctly Mesoamerican artifacts, with metals playing a particularly important role in the sacred and symbolic cultural realms. Possible location of Mesoamerican metallurgy West Mexico The earliest and most diverse finds of metal artifacts are from Wes ...

La Huasteca
La Huasteca is a geographical and cultural region located partially along the Gulf of Mexico and including parts of the states of Tamaulipas, Veracruz, Puebla, Hidalgo, San Luis Potosí, Querétaro and Guanajuato. It is roughly defined as the area in which the Huastec people had influence when their civilization was at its height during the Mesoamerican period. Today, the Huastecs occupy only a fraction of this region with the Nahua people now the most numerous indigenous group. However, those who live in the region share a number of cultural traits such as a style of music and dance, along with religious festivals such as Xantolo. Geography and environment Historically and ethnically, the Huasteca region is defined by the area dominated by the Huastecs at their height. The actual extension of the region is somewhat disputed as well as how it should be sub-divided. Geographically it has been defined as from the Sierra Madre Oriental to the Gulf of Mexico with the Sierra de Tamau ...

Elite
In political and sociological theory, the elite (french: élite, from la, eligere, to select or to sort out) are a small group of powerful people who hold a disproportionate amount of wealth, privilege, political power, or skill in a group. Defined by the ''Cambridge Dictionary'', the "elite" are "those people or organizations that are considered the best or most powerful compared to others of a similar type." American sociologist C. Wright Mills states that members of the elite accept their fellows' position of importance in society. "As a rule, 'they accept one another, understand one another, marry one another, tend to work, and to think, if not together at least alike'." It is a well-regulated existence where education plays a critical role. Universities in the US Youthful upper-class members attend prominent preparatory schools, which not only open doors to such elite universities as Harvard, Yale, Princeton, and the University of Pennsylvania, but also to the universit ...

Jalisco
Jalisco (, , ; Nahuatl: Xalixco), officially the Free and Sovereign State of Jalisco ( es, Estado Libre y Soberano de Jalisco ; Nahuatl: Tlahtohcayotl Xalixco), is one of the 31 states which, along with Mexico City, comprise the 32 Federal Entities of Mexico. It is located in Western Mexico and is bordered by six states, which are Nayarit, Zacatecas, Aguascalientes, Guanajuato, Michoacán, and Colima. Jalisco is divided into 125 municipalities, and its capital and largest city is Guadalajara. Jalisco is one of the most economically and culturally important states in Mexico, owing to its natural resources as well as its long history and culture. Many of the characteristic traits of Mexican culture, particularly outside Mexico City, are originally from Jalisco, such as mariachi, ranchera music, birria, tequila, jaripeo, etc., hence the state's motto: "Jalisco es México." Economically, it is ranked third in the country, with industries centered in the Guadalajara metropolit ...

Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people.

It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ...

Cold Working
In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold work", cutting or grinding a formed object. Cold forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. They generally have the advantage of being simpler to carry out than hot working techniques. Unlike hot working, cold working causes the crystal grains and inclusions to distort following the flow of the metal; which may cause work hardening and anisotropic material properties. Work hardening makes the metal harder, stiffer, and stronger, but less plastic, and may cause cracks of the piece. The possible uses of cold forming are extremely v ...
