The solar-electromagnetic- and corpuscular-radiation pressure and the associated Poynting-Robertson effect increase in effectiveness as the particle size decreases and modify the distribution and limit sizes to larger than a few microns.

but after that, if thumb-sucking pressure is frequent, it will have an effect.

Thus if the instrument depends on the pressure or suction effect alone, and this pressure or suction is measured against the air pressure in an ordinary room, in which the doors and windows are carefully closed and a newspaper is then burnt up the chimney, an effect may be produced equal to a wind of 10 mi / h ( 16 km / h ); and the opening of a window in rough weather, or the opening of a door, may entirely alter the registration.

Because there is no selection pressure for sight in this environment, any number of genetic abnormalities that give rise to the damage or loss of eyes could proliferate among the population with no effect on the fitness of the population.

At these very high vacuums the effect of photon radiation pressure on the vanes can be observed in very sensitive apparatus ( see Nichols radiometer ) but this is insufficient to cause rotation.

The imbalance of this effect between the warmer black side and the cooler silver side means the net pressure on the vane is equivalent to a push on the black side, and as a result the vanes spin round with the black side trailing.

In fact, at separations of 10 nm — about 100 times the typical size of an atom — the Casimir effect produces the equivalent of 1 atmosphere of pressure ( 101. 325 kPa ), the precise value depending on surface geometry and other factors.

On the other hand the long-term effect is due to an unknown vasodilator effect that decreases blood pressure by decreasing resistance.

After the sun sets and the temperature drops, the warm wall will then continue to transfer heat to the interior for several hours due to the time lag effect.

* BCS theory correctly predicts the Meissner effect, i. e. the expulsion of a magnetic field from the superconductor and the variation of the penetration depth ( the extent of the screening currents flowing below the metal's surface ) with temperature.

* The BCS theory reproduces the isotope effect, which is the experimental observation that for a given superconducting material, the critical temperature is inversely proportional to the mass of the isotope used in the material.

The sterilizing effect of cooking will depend on temperature, cooking time, and technique used.

The current north of the Canaries, has a cooling effect on the islands of Cape Verde, making the air temperature more bearable than it would expect in any case at this latitude.

The voltage drop across a forward-biased diode varies only a little with the current, and is a function of temperature ; this effect can be used as a temperature sensor or voltage reference.

A simple example from the physical world is the heating of water: a one degree increase in temperature is a quantitative change, but between water of 100 degrees and steam of 100 degrees ( the effect latent heat ) there is a qualitative change.

Similarly, thermocouples use the Peltier-Seebeck effect to measure the temperature difference between two points.

* Thermoelectric effect, the direct conversion of temperature differences to electricity, as in thermocouples, thermopiles, and thermionic converters.

ETC increases the performance of conventional solid propellants, reduces the effect of temperature on propellant expansion and allows for more advanced, higher density propellants to be used.

ETC increases the performance of conventional solid propellants, reduces the effect of temperature on propellant expansion and allows for more advanced, higher density propellants to be used.

The effect of this is that, in restricted environments, such as when fatty acids are part of a phospholipid in a lipid bilayer, or triglycerides in lipid droplets, cis bonds limit the ability of fatty acids to be closely packed, and therefore could affect the melting temperature of the membrane or of the fat.

The effect of the field in this case is to reduce the effective binding energy of the atom to the surface and to give, in effect, a greatly increased evaporation rate relative to that expected at that temperature at zero fields.

Gadolinium demonstrates a magnetocaloric effect whereby its temperature increases when it enters a magnetic field and decreases when it leaves the magnetic field.

The temperature lowered to () for the gadolinium alloy Gd < sub > 85 </ sub > Er < sub > 15 </ sub >, and the effect is considerably stronger for the alloy Gd < sub > 5 </ sub >( Si < sub > 2 </ sub > Ge < sub > 2 </ sub >), but at a much lower temperature (<).

The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect.

* Hot spot effect in subatomic physics, regions of high energy density or temperature in hadronic or nuclear matter
