Mississippian Copper Plates
Mississippian copper plates, or plaques, are plain and repousséd plates of beaten copper crafted by peoples of the various regional expressions of the Mississippian culture between 800 and 1600 CE. They have been found as artifacts in archaeological sites in the American Midwest and Southeast. The plates, found as far afield as Florida, Georgia, Illinois, Mississippi, Oklahoma, Tennessee, and Wisconsin, were instrumental in the development of the archaeological concept known as the Southeastern Ceremonial Complex. Some of the more notable examples are representations of raptorial birds and avian-themed dancing warriors. Copper in the Eastern Woodlands Copper trade routes throughout the Eastern Woodlands were established during the Archaic period (3000 - 1000 BCE) and continued into historic times.Brose et al. (1985), Ancient Art of the American Woodlands Indians : 149 Copper was usually imported from the Great Lakes region; however other sources of copper have been found el ...

Trail Of Tears
The Trail of Tears was an ethnic cleansing and forced displacement of approximately 60,000 people of the "Five Civilized Tribes" between 1830 and 1850 by the United States government. As part of the Indian removal, members of the Cherokee, Muscogee (Creek), Seminole, Chickasaw, and Choctaw nations were forcibly removed from their ancestral homelands in the Southeastern United States to newly designated Indian Territory west of the Mississippi River after the passage of the Indian Removal Act in 1830. The Cherokee removal in 1838 (the last forced removal east of the Mississippi) was brought on by the discovery of gold near Dahlonega, Georgia, in 1828, resulting in the Georgia Gold Rush. The relocated peoples suffered from exposure, disease, and starvation while en route to their newly designated Indian reserve. Thousands died from disease before reaching their destinations or shortly after. Some historians have said that the event constituted a genocide, although this label ...

Chunkey
Chunkey (also known as chunky, chenco, tchung-kee or the hoop and stick game ) is a game of Native American origin. It was played by rolling disc-shaped stones across the ground and throwing spears at them in an attempt to land the spear as close to the stopped stone as possible. It originated around 600 CE in the Cahokia region of what is now the United States (near modern St. Louis, Missouri). Chunkey was played in huge arenas as large as 47 acres (19 ha) that housed great audiences designed to bring people of the region together (i.e. Cahokians, farmers, immigrants, and even visitors). It continued to be played after the fall of the Mississippian culture around 1500 CE. Variations were played throughout North America. Early ethnographer James Adair translated the name to mean "running hard labor". Gambling was frequently connected with the game, with some players wagering everything they owned on the outcome of the game. Losers were even known to commit suicide. Graphic re ...

Frank Hamilton Cushing
Frank Hamilton Cushing (July 22, 1857 in North East Township, Erie County, Pennsylvania – April 10, 1900 in Washington, D.C.) was an American anthropologist and ethnologist. He made pioneering studies of the Zuni Indians of New Mexico by entering into their culture; his work helped establish participant observation as a common anthropological research strategy. In recent years, however, questions have emerged about Cushing's activities among the Zuni. Consequently, Frank Cushing's work provides an important case study for considering the ethics of both ethnographic research and the generation of museum collections. Early life Cushing was born in the borough of North East, Pennsylvania. He later moved with his family to Western New York. As a boy he took an interest in the Native American artifacts in the surrounding countryside and taught himself how to knap flint (make arrowheads and such from flint). He published his first scientific paper when he was 17. After a brief pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional w ...

Laminate
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a permanently assembled object created using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used. Materials There are different lamination processes, depending primarily on the type or types of materials to be laminated. The materials used in laminates can be identical or different, depending on the process and the object to be laminated. Textile Laminated fabric are widely used in different fields of human activity, including medical and military. Woven fabrics (organic and inorganic based) are usually laminated by different chemical polymers to give them useful properties like chemical resistance, dust, grease, windproofness, photolumine ...

Annealing (metallurgy)
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling. In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. As the material cools it recrystallizes. For many alloys, including carbon steel, the crystal grain size and phase composition, which ultimately determine the material properties, are dependent on the heating rate and cooling rate. Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram, heat treatment can be used to ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert R
Robert Lee Rayford (February 3, 1953 – May 15 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America based on evidence which was published in 1988 in which the authors claimed that medical evidence indicated that he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported once at a scientific conference in Australia in 1999; however, the data has never been published in a peer-reviewed medical or scientific journal. Background Robert Rayford was born on February 3, 1953, in St. Louis, Missouri to Constance Rayford (September 12, 1931 – April 3, 2011) and Joseph Benny Bell (March 24, 1 ...

Mound 34
Mound 34 is a small platform mound located roughly to the east of Monks Mound at Cahokia Mounds near Collinsville, Illinois. Excavations near Mound 34 from 2002 to 2010 revealed the remains of a copper workshop, although the one of a kind discovery had been previously found in the late 1950s by archaeologist Gregory Perino, but lost for 60 years. It is so far the only remains of a copper workshop found at a Mississippian culture archaeological site. Construction sequence From the Emergent Mississippian period (beginning approximately 800 CE) to the Stirling Phase (1000 to 1200 CE) the location was a village site with multiple houses, pit features, extensive midden deposits, a copper worskop, and a large structure (possibly as large as by ) with a centrally located hearth. Early in the Moorehead Phase (1200 - 1275 CE) the entire area east of Cahokia saw an intensive construction episode. The village area and all of its structures was razed and the "Ramey Plaza" and its associat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
