The observed stabilization of HCFC concentrations (left graphs) and the growth of HFCs (right graphs) in earth's atmosphere. The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, sulfur dioxide, methyl chloride, or propane, that could result in fatal accidents when they leaked.
In the 20th century, bedpans were made of ceramic, enamel, or stainless steel, and after the 1960s, bedpan materials expanded to include plastics and disposable substances. [6] The initial bedpan patent US2243791A was created in the United States in the 1940s. Today, most bedpans are made of stainless steel, plastic, or disposable materials ...
Additional corrections and minor revisions were made in 2004 and 2006.

In June 2007, the American Medical Association declared that "implantable radio frequency identification (RFID) devices may help to identify patients, thereby improving the safety and efficiency of patient care, and may be used to enable secure access to patient clinical information", [54] but in the same year, news reports linking similar ...
In semiconductor technology, copper interconnects are interconnects made of copper. They are used in silicon integrated circuits (ICs) to reduce propagation delays and power consumption . Since copper is a better conductor than aluminium , ICs using copper for their interconnects can have interconnects with narrower dimensions, and use less ...
