Human ancestors manufactured objects using stone and other tools long before the emergence of Homo sapiens about 200,000 years ago. [6] The earliest methods of stone tool making, known as the Oldowan " industry ", date back to at least 2.3 million years ago, [ 7 ] with the earliest direct evidence of tool usage found in Ethiopia within the ...
Products manufactured for medical or food use must be produced in facilities designed and operated according to Good Manufacturing Practice (GMP) regulations. Cleanrooms are often required to control the levels of particulates and microorganisms. Sterilization and aseptic processing equipment are required for production of injectable products.
About half of all fibres are synthetic, with applications in every field of fiber and textile technology. Although many classes of fibers based on synthetic polymers have been evaluated as potentially valuable commercial products, four of them - nylon, polyester, acrylic and polyolefin - dominate the market. These four account for approximately ...
New Orleans-based artist Jean-Marcel St. Jacques made his name cobbling together "wooden quilts," salvaging wood leftover from Hurricane Katrina to help restore his family's historic home.
The wearing of clothing is exclusively a human characteristic and is a feature of most human societies. There has always been some disagreement among scientists on when humans began wearing clothes, but newer studies from The University of Florida involving the evolution of body lice suggest it started sometime around 170,000 years ago.
The C. glutamicum species is widely used for producing glutamate and lysine, [16] components of human food, animal feed and pharmaceutical products. Expression of functionally active human epidermal growth factor has been done in C. glutamicum , [ 17 ] thus demonstrating a potential for industrial-scale production of human proteins.
In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the power used for work and transport. A variety of living things serve as models in biological research, such as in genetics, and in drug testing.
A selection of simulated "swimbots" Artificial life (ALife or A-Life) is a field of study wherein researchers examine systems related to natural life, its processes, and its evolution, through the use of simulations with computer models, robotics, and biochemistry. [1]
