Colloidal Silver
The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia. There is tentative evidence that using silver-alloy indwelling catheters for short-term catheterizing will reduce the risk of catheter-acquired urinary tract infections. Silver generally has low toxicity, and minimal risk is expected when silver is used in approved medical applications. Alternative medicine products such as colloidal silver are not safe or effective. Mechanism of action Silver and most silver compounds have an oligodynamic effect and are toxic for bacteria, algae, and fungi ''in vitro''. The antibacterial action of silver is dependent on the silver ion. The effectiveness of silver co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sawdust
Sawdust (or wood dust) is a by-product or waste product of woodworking operations such as sawing, sanding, milling, planing, and routing. It is composed of small chippings of wood. These operations can be performed by woodworking machinery, portable power tools or by use of hand tools. Wood dust is also the byproduct of certain animals, birds and insects which live in wood, such as the woodpecker and carpenter ant. In some manufacturing industries it can be a significant fire hazard and source of occupational dust exposure. Sawdust, as particulates, is the main component of particleboard. Research on health hazards comes from the field of occupational safety and health, and study of ventilation happens in indoor air quality engineering. Formation Two waste products, dust and chips, form at the working surface during woodworking operations such as sawing, milling and sanding. These operations both shatter lignified wood cells and break out whole cells and groups of cells. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terra-cotta
Terracotta, terra cotta, or terra-cotta (; ; ), in its material sense as an earthenware substrate, is a clay-based unglazed or glazed ceramic where the fired body is porous. In applied art, craft, construction, and architecture, terracotta is the term normally used for sculpture made in earthenware and also for various practical uses, including vessels (notably flower pots), water and waste water pipes, roofing tiles, bricks, and surface embellishment in building construction. The term is also used to refer to the natural brownish orange color of most terracotta. In archaeology and art history, "terracotta" is often used to describe objects such as figurines not made on a potter's wheel. Vessels and other objects that are or might be made on a wheel from the same material are called earthenware pottery; the choice of term depends on the type of object rather than the material or firing technique. Unglazed pieces, and those made for building construction and industry, are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kiln
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many other materials. Pronunciation and etymology According to the Oxford English Dictionary, kiln was derived from the words cyline, cylene, cyln(e) in Old English, in turn derived from Latin ''culina'' ("kitchen"). In Middle English the word is attested as kulne, kyllne, kilne, kiln, kylle, kyll, kil, kill, keele, kiele. For over 600 years, the final "n" in kiln was silent. It wasn't until the late 20th century where the "n" began to be pronounced. This is due to a phenomenon known as spelling pronunciation, where the pronunciation of a word is surmised from its spelling an ...

Ivan Illich
Ivan Dominic Illich ( , ; 4 September 1926 – 2 December 2002) was an Austrian Roman Catholic priest, theologian, philosopher, and social critic. His 1971 book '' Deschooling Society'' criticises modern society's institutional approach to education, an approach that constrains learning to narrow situations in a fairly short period of the human lifespan. His 1975 book ''Medical Nemesis'', importing to the sociology of medicine the concept of medical harm, argues that industrialised society widely impairs quality of life by overmedicalising life, pathologizing normal conditions, creating false dependency, and limiting other more healthful solutions. Illich called himself "an errant pilgrim." Biography Early life Ivan Dominic Illich was born on 4 September 1926 in Vienna, Austria, to Gian Pietro Ilic (Ivan Peter Illich) and Ellen Rose "Maexie" née Regenstreif-Ortlieb.

Cuernavaca, Mexico
Cuernavaca (; nci-IPA, Cuauhnāhuac, kʷawˈnaːwak "near the woods", ) is the capital and largest city of the state of Morelos in Mexico. The city is located around a 90-minute drive south of Mexico City using the Federal Highway 95D. The name ''Cuernavaca'' is a euphonism derived from the Nahuatl toponym and means 'surrounded by or close to trees'. The name was Hispanicized to ''Cuernavaca''; Hernán Cortés called it ''Coadnabaced'' in his letters to Charles V, Holy Roman Emperor, and Bernal Díaz del Castillo used the name ''Cuautlavaca'' in his chronicles. The coat-of-arms of the municipality is based on the pre-Columbian pictograph emblem of the city which depicts a tree trunk () with three branches, with foliage, and four roots colored red. There is a cut in the trunk in the form of a mouth, from which emerges a speech scroll, probably representing the language Nahuatl and by extension the locative suffix , meaning 'near'.
