The anti-descriptivist arguments regard the observable properties of instances of a kind C as nomic consequences of the essence of C. If the laws of nature are metaphysically necessary then D will be a necessary property of instances of C also.
According to Putnam, when people used the term 'water', even in 1750, they intended to refer to natural kind, a kind of thing whose instances share a common nature, not directly observable, which explains the observable properties of instances of the kind.
One can "calibrate" a set of control variables in terms of aggregate properties, for instance by keeping track of how many cases are created (new members of C U (t)) and how many are treated (new members of C T (t)).
The criteria are applied differently for different types of properties; for instance, maritime properties have application guidelines different from those of buildings.
More specifically, such a reductionism amounts to the assumption that properties and interactions of individuals alone suffice to explain all behavior at the level of populations (and higher units): there is no need to refer to higher level or systemic properties which cannot be defined in terms of individual properties (for instance, the density of a population).
Some 30 men and women are developing nanostructured coating materials that vastly improve the mechanical features durability and thermal properties, for instance–of parts made from conventional metals like steel and bronze.
These tools use the expectation maximization algorithm to separate correct from incorrect identifications based on a limited set of rules (one of the dominant properties, for instance, is the tryptic correctness of the peptide termini).
The grain reflects a process-induced anisotropy of certain properties, for instance tensile strength, orientation (or anisotropy) of the material resulting from some stages of the whole processing steps that involve strong flows, such as milling.
However, polymer ion-exchange membranes are poisoned with organic solvents [41, 42]: reorganization of their porous structure results in deterioration of functional properties, for instance, it enhances methanol crossover [42].
Furthermore, by combining two of the largest groups of oxides, plenty of new physical properties, for instance, interfacial magnetism6 and superconductivity7 as observed in the perovskite-type LAO/STO interface, may be found at the γ-Al2O3/STO heterointerface.
Cellphones and their radiation have been tested for many of these properties — for instance, their ability to chemically modify DNA without causing mutations — but evidence linking this form of radiation to such cellular changes remains largely negative.
