UL has six basic services it offers to manufacturers, inspection authorities, or government officials. These are product listing service, classification, service, component recognition service, certificate service, inspection service, and fact finding and research. UL s Electrical Department is in charge of evaluating individual plastics and other products using plastics as components. The Electrical Department evaluates consumer products such as TV sets, power tools, appliances, and industrial and commercial electrical equipment and components. 

Component recognition is typically obtained from the configuration of the I/Os. The I/O configuration includes two attributes the I/O s shape, whether it is a beam lead, gull-wing... 

Fuzzy logic and fuzzy set theory are applied to various problems in chemistry. The applications range from component identification and spectral Hbrary search to fuzzy pattern recognition or calibrations of analytical methods. 

This mode of molecular recognition, on principle, is defined as the recognition of like from unlike or self from unself-molecules, embodied in the spontaneous selection and preferential assembly of like components in a mixture (9). 

A particular point of interest included in these hehcal complexes concerns the chirality. The heUcates obtained from the achiral strands are a racemic mixture of left- and right-handed double heUces (Fig. 34) (202). This special mode of recognition where homochiral supramolecular entities, as a consequence of homochiral self-recognition, result from racemic components is known as optical self-resolution (203). It appears in certain cases from racemic solutions or melts (spontaneous resolution) and is often quoted as one of the possible sources of optical resolution in the biological world. On the other hand, the more commonly found process of heterochiral self-recognition gives rise to a racemic supramolecular assembly of enantio pairs (204). 

Another synthetic strategy is based on self-assembly driven by molecular recognition between complementary TT-donors and 7T-acceptors. Examples include the synthesis of catenanes and rotaxanes that can act as controUable molecular shuttles (6,236). The TT-donors in the shuttles are located in the dumb-beU shaped component of the rotaxane and the 7T-acceptors in the macrocycHc component, or vice versa. The shuttles may be switched by chemical, electrochemical, or photochemical means. 

Equation 6 shows that the adsorption of component 1 at a partial pressureis reduced in the presence of component 2 as a result of competition for the available surface sites. There ate only a few systems for which this expression (with 5 1 = q 2 = 5 ) provides an accurate quantitative representation, but it provides useful quaUtative or semiquantitative guidance for many systems. In particular, it has the correct asymptotic behavior and provides expHcit recognition of the effect of competitive adsorption. For example, if component 2 is either strongly adsorbed or present at much higher concentration than component 1, the isotherm for component 1 is reduced to a simple linear form in which the apparent Henry s law constant depends onp. ... 

Dmg receptors are chemical entities which are typically, but not exclusively, small molecules that interact with cellular components, frequently at the plasma membrane level (1,2). There are many types of receptors heat, light, immune, hormone, ion channel, toxin, and vims are but a few that can excite a cell. The receptor concept can be appHed generally to signal recognition processes where a chemical or physical signal is recognized. This recognition is translated into response (Fig. 3) and the process can be seen as a flow of information. 

Additional compounds having similar biological activities and stmctural components were isolated resulting in the recognition of PGs as a family of closely related compounds. Stmctural and stereochemical assignments of PGE and PGF, were confirmed by x-ray crystallographic analysis of their... 

In a biocatalytic biosensor the molecular recognition component is an enzyme. Enzymes, macromolecular catalysts that are manufactured by plants and animals, affect the rates of biochemical reactions. Virtually all of the millions of chemical reactions involved in Hfe processes have associated enzymes controlling the rates. CoUectively, there are several thousand enzymes known and perhaps many thousand more yet to be discovered. 

The two zinc ions fulfill important but different functions in the DNA-binding domains. The first zinc ion is important for DNA-bindlng because it properly positions the recognition helix the last two cysteine zinc ligands are part of this helix. The second zinc ion is important for dimerization since the five-residue loop between the first two cysteine zinc ligands is the main component of the dimer interaction area.
