SubClass Of: morphological quality

Class Hierarchy

owl:Thing › bfo:entity › bfo:continuant › bfo:specifically dependent continuant › bfo:quality › morphological quality › physical structure

Direct subclasses:

• amorphous structure
• crystalline structure
• protein secondary structure
• protein tertiary structure
• semi-crystalline structure

Definition

morphological quality that inheres in a material entity by virtue of the relative positions, arrangement, and connectivity of the material parts within that entity

Explanatory Notes

This quality concerns the organization of parts (spatial arrangement and connectivity) at whatever granularity is relevant (e.g., anatomical regions, microstructure, particle packing, macromolecular conformation).

Examples

• Physical structure of a granulated culture medium by virtue of the arrangement of powder particles within granules; Physical structure of a crystalline excipient by virtue of its crystal lattice organization; Physical structure of a chromatography resin bead by virtue of its porous internal organization;

Primitive Class

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

Primitive Rationale

There are insufficient constructs for creating a set of necessary and sufficient conditions

Formal Axioms

First-Order Logic Axioms

PhysicalStructure(x) → MorphologicalQuality(x) ∧ ∃m (MaterialEntity(m) ∧ qualityOf(x, m))

Semi-Formal Natural Language Axioms

if x is a ‘physical structure’ then x is a ‘morphological quality’ and is ‘quality of’ some ‘material entity’
