Cinnamomum cassia component called coumarin, which could damage the liver if consumed in larger amounts, European health agencies have warned against consuming high amounts of cassia. Other bioactive compounds found in the bark, powder and essential oils of "C. cassia" are cinnamaldehyde and styrene. In high doses these substances can also be toxic for humans. Cinnamomum cassia Cinnamomum cassia, called Chinese cassia or Chinese cinnamon, is an evergreen tree originating in southern China, and widely cultivated there and elsewhere in southern and eastern Asia (India, Indonesia, Laos, Malaysia, Taiwan, Thailand, and Vietnam). It is one of several species of "Cinnamomum" used primarily
SPICE effect of component variations on performance, a task which is impractical using calculations by hand for a circuit of any appreciable complexity. Circuit simulation programs, of which SPICE and derivatives are the most prominent, take a text netlist describing the circuit elements (transistors, resistors, capacitors, etc.) and their connections, and translate this description into equations to be solved. The general equations produced are nonlinear differential algebraic equations which are solved using implicit integration methods, Newton's method and sparse matrix techniques. SPICE was developed at the Electronics Research Laboratory of the University of California, Berkeley by Laurence Nagel with direction from
