Communication Function Classification System         
CFCS
The Communication Function Classification System (CFCS) for individuals with cerebral palsy (CP) is a five-level classification system which began development at Michigan State University and currently under further refinement at the University of Wyoming.
Chlorofluorocarbon         
Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon.

Chlorofluorocarbon

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane.

The most common representative is dichlorodifluoromethane (R-12). R-12 is also commonly called Freon and is used as a refrigerant. Many CFCs have been widely used as refrigerants, propellants (in aerosol applications), and solvents. Because CFCs contribute to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) including R-410A and R-134a.

1. These include carbon dioxide (CO2), methane, nitrous oxide and chlorofluorocarbons (CFCs) and the replacements for CFCs.
2. The gases include carbon dioxide, methane, nitrous oxide, CFCs and the current replacements for CFCs, and have been measured since 1'7' by NOAA‘s global sampling network.
3. Ozone–destroying chlorofluorocarbons (CFCs) have been generally phased out.
4. "The aim is to reach zero imports of CFCs by 2010," he said.
5. "CFCs have a very long lifetime," explains Joanna Haigh, professor of atmospheric physics at Imperial College.
