The stoichiometry for ceil growth is very complex and varies with microorgan-ismynutrienl system and environmental conditions such as pH, temperature, and redox potential. This complexity Is especially true when more than one nutrient contributes to cell growth, as is usually the case. We shall focus our discussion on a. simplified version for cell growth, one that is limited by only one nutrient in the medium. In general, we have... 

FIRE SIMULATOR predicts the effects of fire growth in a 1-room, 2-vent compartment with sprinkler and detector. It predicts temperature and smoke properties (Oj/CO/COj concentrations and optical densities), heat transfer through room walls and ceilings, sprinkler/heat and smoke detector activation time, heating history of sprinkler/heat detector links, smoke detector response, sprinkler activation, ceiling jet temperature and velocity history (at specified radius from the flre i, sprinkler suppression rate of fire, time to flashover, post-flashover burning rates and duration, doors and windows which open and close, forced ventilation, post-flashover ventilation-limited combustion, lower flammability limit, smoke emissivity, and generation rates of CO/CO, pro iri i post-flashover. 

Historically, the development of animal cell culture systems has been dependent upon the development of new types of tissue culture media. Mouse L cells and HeLa cells were developed using a balanced salt solution supplemented with blood plasma, an embryonic tissue extract, and/or serum. In 1955 Eagle developed a nutritionally defined medium, containing all of the essential amino acids, vitamins, cofactors, carbohydrates, salts, and small amounts of dialyzed serum (Table 1). He demonstrated that this minimal essential medium (MEM) supported the long-term growth of mouse L and HeLa ceils. Eagle s MEM was so well defined that the omission of a single essential nutrient eventually resulted in the death of these animal cells in culture.

The entropy term is negative so that it is the enthalpy or energy term that drives the polymerization. At low temperatures, the enthalpy term is larger than the TASp term so that polymer growth occurs. At some temperature, called the ceiling temperature, the enthalpy and the entropy terms are the same and AGp = 0. Above this temperature depolymerization occurs more rapidly than polymer formation so that polymer formation does not occur. At the ceiling temperature depolymerization and polymerization rates are equal. The ceiling temperature is then defined as...

NFPA 286 Standard Method of Tests for Evaluating Contribution of Wall and Ceiling Interior Finish to Room Fire Growth. National Fire Protection Association, Quincy, MA. 

One of the simplest large-scale geometries relevant to real world fire growth modeling is vertical upward flame spread on a free-standing wall, meaning that the wall is not part of a compartment. Compartment effects, such as accumulation of a hot ceiling layer, do not come into play. 

The majority of the materials with low flame spread (or low heat release) also exhibit low smoke release. However, it has been shown in several series of room-corner test projects (with the tested material lining either the walls or the walls and the ceiling), that -10% of the materials tested (8 out of 84) exhibited adequate heat-release (or fire growth) characteristics, but have very high smoke release (Table 21.17 and Figure 21.16).189190 These materials would cause severe obscuration problems if used in buildings. A combination of this work, and the concept that a visibility of 4 m is reasonable for people familiar with their environment,191 has led all the U.S. codes to include smoke pass/fail criteria when room-corner tests are used as alternatives to the ASTM E 84 Steiner tunnel test.
