Hydraulic cements ( e. g., Portland cement ) harden because of hydration, chemical reactions that occur independently of the mixture's water content ; they can harden even underwater or when constantly exposed to wet weather.

High inside pressure inhibits motion because the temperature differences are not enough to push the vanes through the higher concentration of air: there is too much air resistance for " eddy currents " to occur, and any slight air movement caused by the temperature difference is damped by the higher pressure before the currents can " wrap around " to the other side.

# As experiences occur in the life of the individual, they are either, a ) symbolized, perceived and organized into some relation to the self, b ) ignored because there is no perceived relationship to the self structure, c ) denied symbolization or given distorted symbolization because the experience is inconsistent with the structure of the self.

* Impurities occur because materials are never 100 % pure.

Diatomic elements played an important role in the elucidation of the concepts of element, atom, and molecule in the 19th century, because some of the most common elements, such as hydrogen, oxygen, and nitrogen, occur as diatomic molecules.

Declinations with magnitudes greater than 90 ° do not occur, because the poles are the northernmost and southernmost points of the celestial sphere.

If there is a change in the potential energy of a system ; for example μ < sub > 1 </ sub >> μ < sub > 2 </ sub > ( μ is Chemical potential ) an energy flow will occur from S < sub > 1 </ sub > to S < sub > 2 </ sub >, because nature always prefers low energy and maximum entropy.

Reporting of OTC amounts are difficult because trades can occur in private, without activity being visible on any exchange.

Assigning weighted values and achieving consensus on all PV quantities yields an important benefit of EVM, because it exposes misunderstandings and miscommunications about the scope of the project, and resolving these differences should always occur as early as possible.

However, it should be noted that because of risks associated with oxygen toxicity, divers tend not to utilize nitrox at greater depths where more pronounced narcosis symptoms are more likely to occur.

Conversion disorder can be distinguished from epilepsy because the episodes never occur during sleep and do not involve incontinence or self-injury.

At present in 2007 the practice of nanotechnology embraces both stochastic approaches ( in which, for example, supramolecular chemistry creates waterproof pants ) and deterministic approaches wherein single molecules ( created by stochastic chemistry ) are manipulated on substrate surfaces ( created by stochastic deposition methods ) by deterministic methods comprising nudging them with STM or AFM probes and causing simple binding or cleavage reactions to occur.
