stability constant
spit relatively long narrow shoal, bank, or reef extending from the shore into a
water body. Primarily a small point or low tongue of land consisting of sand
(sandspit) or gravel deposited by longshore drifting, having one end attached
to the mainland and the other terminating in the open water. ~coast.
sponges ~Porifera.
spongin horny skeletal substance of certain sponges.
spore single-celled or several-celled reproductive body that becomes detached
from the parent and gives rise either directly or indirectly to a new individual. Many different types usually of microscopic size, and produced in a
variety of ways. Thin- or thick-walled; often produced in enormous numbers and distributed far and wide by wind, water, animals; others are resting
spores, the means of survival through an unfavorable period. Occurring
particularly in Fungi, Bacteria, and Protozoa.
Sporozoa (sporozoans) ~Protozoa.
spray in coastal regions the impact of salt spray depends on the major wind
directions, wind force and coastal morphology. Salt spray affects the vegetation of the spray zone (zone above the high water line), so that only salt- and
wind-tolerant species will survive. Salt spray usually has a composition
slightly different from that of sea salt itself, due to separation processes during bubble and droplet formation.
spring tide tidal period during which the phases of the semi-diurnal lunar and solar
tides coincide and their effects add to give a larger tidal range, with high water
and low water both attaining relatively extreme values. Spring tide occurs
about once every fortnight, and alternates with neap tide after about 1 week.
stability the degree to which the effects of disturbances are compensated by
restoring forces. Static stabilility in hydrodynamics is a stable situation
when the fluid is at rest. When the fluid is moving the effect of additional
forces has to be taken into account, to assess the dynamic stability.
stability constant K st a term reserved for the equilibrium constant of complex
formation between elements and ligands (the ions/atoms/molecules surrounding the central atom of a complex ion), either organic or inorganic.
The factor is defined by the ratio of complex concentration to those of element and ligand concentrations. If more complexes are possible and the
reactions are step-wise, there may be subsequent Kst!, K st2 ' etc.
