SubClass Of: homogeneity

Class Hierarchy

owl:Thing › bfo:entity › bfo:continuant › bfo:specifically dependent continuant › bfo:quality › homogeneity › quality homogeneity

Definition

homogeneity inhering in a material entity by virtue of the extent to which one or more qualities of that material entity are uniformly distributed throughout that material entity

Examples

• Quality homogeneity of pH throughout a prepared buffer lot after mixing; Quality homogeneity of osmolality throughout a cell culture medium lot before release for use; Quality homogeneity of electrical conductivity throughout a chromatography buffer preparation;

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs to create a set of necessary and sufficient conditions.

Formal Axioms

First-Order Logic Axioms

QualityHomogeneity(x) → Homogeneity(x) ∧ ∃m∃q (MaterialEntity(m) ∧ Quality(q) ∧ qualityOf(x, m) ∧ specificallyDependsOn(x, q) ∧ qualityOf(q, m))

Semi-Formal Natural Language Axioms

if x is a ‘quality homogeneity’, then x is a ‘homogeneity’ that is the ‘quality of’ some ‘material entity’ m, and x ‘specifically depends on’ some ‘quality’ q that is also the ‘quality of’ that same material entity m
