However, the surface temperature gradient can produce erroneous vapor-pressure measurements for the bulk liquid helium unless precautions are taken to isolate the tube ( which passes through the surface to the vapor pressure bulb ) from the liquid helium surface.

However, with proper modifications, it can be utilized to analyze liquid samples as well as nonconducting materials by mixing them with a conductor ( e. g. graphite ).

However, because of the relatively small diffusion rates in solids, the corresponding chemical reactions are very slow in comparison to liquid and gas phase reactions.

However, this equation becomes increasingly inaccurate at higher pressures and lower temperatures, and fails to predict condensation from a gas to a liquid.

However, skating is possible at temperatures much lower than − 20 ° C, at which temperature there is no naturally occurring film of liquid.

However, because dyes are dissolved in the liquid phase, they have a tendency to soak into paper, making the ink less efficient and potentially allowing the ink to bleed at the edges of an image.

However some techniques, such as the use of boundaries or an applied electric field, can be used to enforce a single ordered domain in a macroscopic liquid crystal sample.

However, some liquid crystals are biaxial nematics, meaning that in addition to orienting their long axis, they also orient along a secondary axis.

However, liquid lubricants are much more effective on account of their high specific heat capacity.

However, aneroid gauges can be used to measure the pressure of a liquid as well as a gas, and they are not the only type of gauge that can operate without fluid.

However, in an underground oil reservoir the proportions of gas, liquid, and solid depend on subsurface conditions and on the phase diagram of the petroleum mixture.

However, there were several innovative games, including Pipe Dream ( also known as " Pipe Mania "), a 1989 release that challenged players to create an unbroken chain of pipes to divert a toxic liquid.

However, small clusters do not exhibit sharp first order phase transitions such as melting, and at the boundary it is not possible to completely categorize the cluster as a liquid or solid, since these concepts are ( without extra definitions ) only applicable to macroscopic systems.

However, like certain other insects that survive on dilute, purely liquid diets, notably many of the Homoptera, many adult mosquitoes must excrete unwanted aqueous fractions even as they feed.

However, the dive has taken too long for Bud to return to the top of the trench before the oxygen in the liquid runs out.

However if the ICP-MS is to be used routinely and is on and running for eight or more hours each day for several days a week, then going with liquid argon will be the most suitable.

However, after the initial rush, these naturally occurring imperfections are typically too small to consistently act as nucleation points as the surface tension of the liquid smoothes out these minute irregularities.

However, at lower temperatures or a higher density, a real fluid deviates strongly from the behavior of an ideal gas, particularly as it condenses from a gas into a liquid or solid.

However, for a simple dishwasher with only a single impeller in the base of the unit, glasses and other deep containers both need direct exposure to the jet, and will block liquid from reaching objects behind them.

For this reason, the liquid is called the “ elixir of the gods .” However, it is not certain whether the native peoples of Mexico had any distilled liquors prior to the Spanish Conquest.

" However he appears not to distinguish between the lubrication of the perineum during arousal and an orgasmic ejaculate when he refers to liquid " which in libidinous women often rushes out at the mere sight of a handsome man.

However, the use of liquid CO < sub > 2 </ sub > caused damage to sensitive components inside the marker, and was phased out in favor of compressed air.

However, if the warm layer completely melts the precipitate, becoming rain, the liquid droplets will continue to fall, and pass through a thin layer of cold air just above the surface.

However, the proposed correlation of the many interrelated properties of crystals will reveal discrepancies in the recorded data and suggest areas for reinvestigation.

However, metallic bonds are more collective in nature than other types, and so they allow metal crystals to more easily deform, because they are composed of atoms attracted to each other, but not in any particularly-oriented ways.

However in nonlinear media, such as some crystals, interactions can occur between light and static electric and magnetic fields — these interactions include the Faraday effect and the Kerr effect.

However, if density is increased to the extent that individual crystals are crushed, the explosive may become more sensitive.

However, once frost forms, the leaf cells may be damaged by sharp ice crystals.

However, visible light has too long a wavelength ( typically, 5500 angstroms ) to observe diffraction from crystals.

However, it is not as well-suited as monochromatic scattering for determining the full atomic structure of a crystal and therefore works better with crystals with relatively simple atomic arrangements.

However, untreated crystals often crack if flash-frozen ; therefore, they are generally pre-soaked in a cryoprotectant solution before freezing.

However, crystals offer a much stronger signal due to their periodicity.

However, it was not possible for many years to make doped crystals with enough precision to show the effect.

However, freezing should not be done to a nevus suspected to be a melanoma, as the ice crystals can cause pathological changes called " freezing artifacts " which might interfere with the diagnosis of the melanoma.

However, this presupposes that the material forms a ' perfect crystal ' without any frozen in entropy ( defects, dislocations ), which is never completely true because crystals always grow at a finite temperature.

However, most Proterozoic anorthosites are deformed, and such large plagioclase crystals have recrystallized to form smaller crystals, leaving only the outline of the larger crystals behind.

However, due to the difficulty of actually fabricating these structures at optical scales ( see Fabrication challenges ), early studies were either theoretical or in the microwave regime, where photonic crystals can be built on the far more readily accessible centimetre scale.

However, the problem still remained insurmountable, until in 1953 Max Perutz discovered that the phase problem in analysis of the diffraction patterns could be solved by multiple isomorphous replacement — comparison of patterns from several crystals ; one from the native protein, and others that had been soaked in solutions of heavy metals and had metal ions introduced in different well-defined positions.

However, observations of snow crystals with a low-temperature scanning electron microscope ( LT-SEM ) clearly show cloud droplets measuring up to on the surface of the crystals.

However, supercooling tends to be less significant where there are particles that act as nuclei for ice crystals, thus precipitating rapid freezing.

However, the existing droplets are needed for the ice crystals to grow into large enough particles to precipitate out.

However, rather than use brute force to destroy humanity, they are using the special objects called time crystals to travel through time changing the course of history, bringing Earth to ruin.

However, when they reach the bridge, they are too late as they see the last few TimeSplitters take the time crystals into various time periods using the time portal.
