Individual identity

Performance characteristic not evaluated +, performance characteristic is evaluated, combination of two or more analytical procedures can compensate for the lack of specificity for an individual identity test. 

Ferrets, Mustek furo, distinguish between anal sac secretions of males and females. Males did not discriminate between the anal gland odors of estrous and anestrous females. Chemical sex differences were found, but no seasonal differences. Males had high concentrations of 2,3-dimethylthietane and/or 3,4-dimethyl-l,2-dithiolane (Fig. 7.6). Most individuals had 2-propylthietane. Clapperton etal. (1988) concluded that the odor of the anal gland provides sexual and territorial signals and cues to individual identity.

Atomic (or Nuclear) Energy Atomic (or Nuclear) Reactions Atomic (or Nuclear) Explosions. In chemical reactions the atomic nuclei maintain their charges, masses, and individual identities. These all change in aromic or nuclear reactions, first revealed in the discovery of radioactivity by Becquerel in 1895 and of radium by the Curies in 1898.

One of the main advantages of the density domain approach is the introduction of a natural model for a quantum chemical representation of formal functional groups [1-3]. Consider the simplest case a single connected density domain DD(a,K) and all the nuclei contained within DD(a,K). The boundary MIDCO G(a,K) of the density domain DD(a,K) separates this subset of the nuclei of the molecule from the rest of the nuclei. This fact indicates that the nuclei embedded within DD(a,K), together with a local electronic density cloud surrounding them, represent a sub-entity of the molecule. This sub-entity has an individual identity, since for a range of density threshold values including the value a, the local electron density cloud is separable from the density cloud of the rest of the molecule. 

The chemical business rules of a compound registration solution define the individual identities of chemical structure representations in order to meaningfully assign a unique corporate ID to each unique structure. After applying these rules, standardized parent structures are stored in a main structure table. The (structure) records from the original compound library data file entering the system are saved into a batch table on which each batch entry is associated with its unique parent structure. All data relating to the physical compound sample remain uniquely associated with this batch entry and thus are also associated with one unique parent structure. 

By contrast, when the product from crude oil is limited to only one or two specific hydrocarbons of fairly high purity, the fraction is called a petrochemical. Examples of petrochemicals are ethylene, propylene, benzene, toluene, and styrene. Refined products are defined by the fraction s boiling point and may be composed of various hydrocarbons. Multiple compounds compose refined-product fractions. In contrast, petrochemicals are single-compound fractions, which are required for feedstocks for other petrochemicals and polymers. More processing and separation (distillation, extraction, etc.) operations are used to extract petrochemical products from processing streams. Thus, more identifiable petrochemical products are processed than refined products. Many specific hydrocarbon compounds can be derived from crude oil. However, these hydrocarbons lose their individual identity when they are grouped together as a refined product. 

Signaling pheromones. Communication of individual identity and status is of enormous importance to most mammals, and they have evolved a variety of chemical cues and chemosensory systems to accomplish this task. Although in many instances the message conveyed is multifaceted, complicating its study, several subtypes can be identified, some of which can have overlapping pheromone function. 

In a sense this approach corrects for the fact that the LE model overemphasizes the point that a molecule is simply a sum of its parts—that is, that the atoms retain their individual identities in the molecule.
