The stringent nature of the incompressible flow equations means that specific mathematical techniques have been devised to solve them.

While these properties are true for incompressible Newtonian Stokes flows, the non-linear and sometimes time-dependent nature of non-Newtonian fluids means that they do not hold in the more general case.

This means that such factors as the health of the parents, particularly the mother, their ability to provide their children with the necessities of life, the degree of population density of a country and the shortage of housing facilities may legitimately be taken into consideration in determining the number of offspring.

The resultant deflection means that in these regions of high curvature, atomic terraces are belied by a strong anisotropy in the detection density.

The above formula means that the curl of a vector field is defined as the infinitesimal area density of the circulation of that field.

This means that the density of an ideal gas can be doubled by doubling the pressure, or by halving the absolute temperature.

As a result, the Hall effect is very useful as a means to measure either the carrier density or the magnetic field.

Formally, this means that the probability density functions or probability mass functions in this class have the form

This means that a solid object in air or in a vacuum, or a significant change in atomic density between the object and what is surrounding it, will usually scatter radar ( radio ) waves from its surface.

This leads to a height variation and thus the image comes from the tip topography across the sample and gives a constant charge density surface ; this means contrast on the image is due to variations in charge density.

The relative density difference means that water supports the body during swimming, and therefore makes swimming low impact compared to surface activities such as running where weight is put on to the joints, and also creates resistance when moving through the water.

Smaller volume means higher energy density and cost is reduced due to the decrease of the conductor length.

Specific gravity usually means relative density with respect to water.

which means " the relative density of substance with respect to reference ".

A greater density of flux lines ( lines per unit area ) means a stronger field.

The elevation of the town of Elmali, which means " Apple Town ," from the density of fruit-bearing groves in the region, is, which is the highest part of the valley below it.

The more general case is described by Poynting's theorem above, where it occurs as a divergence, which means that it can only describe the change of energy density in space, rather than the flow.

As the pressure scale height is almost equal to the density scale height of the primary constituent, and since the Knudsen number is the ratio of mean free path and typical density fluctuation scale, this means that the exobase lies in the region where.

These satellites were to be used to measure electron density over time, and include a magnetometer, as well as a means for measuring ambient radio noise.

It follows that 1 % greater density means that the distance travelled before leaving the system is 1 % less.

At the 1999 census there were 269, 774 inhabitants on the territory of the province of Rouergue, which means a density of only 30 inh.

This method can be extended ( in theory ) to concave shapes where the centroid lies outside the shape, and to solids ( of uniform density ), but the positions of the plumb lines need to be recorded by means other than drawing.

Ethanol has a smaller energy density than does gasoline ; this fact means that it takes more fuel ( volume and mass ) to produce the same amount of work.

A week in arrears, and without means to pay, I must go, it is the only right thing.

He must show at the outset that he means exactly what he says.

That means that, if we are to achieve a new standard of leadership, we must think in terms of the total context of our situation.

The microscope and orthicon are both selected to operate well into the ultraviolet spectrum, which means that all lenses must be quartz.

There must also be additional and more fundamental discrimination in the use of means of resistance, violent or non-violent.

When we say that a mythological mode of thought must be completely abandoned, we mean it must be abandoned as the sole or proper means for presenting the Christian understanding of existence.

The Department of Agriculture averaged out U.S. food consumption last year at 1,488 lbs. per person, which, allowing for the 17 million Americans that John Kennedy said go to bed hungry every night, means that certain gluttons on the upper end must somehow down 8 lbs. or more a day.

This means that the programmer must know a " language " that is effective relative to the target computing agent ( computer / computor ).

This is sometimes expressed as " everything that is true is provable ", but it must be understood that " true " here means " made true by the set of axioms ", and not, for example, " true in the intended interpretation ".

But it must also be noted that he used several indirect means to obtain and support his authority with the people.

As with all phobias, the strength of the associations means the individual must not actively pursue the consequences, and outsiders should not in any way undermine and " play " with the phobia in the meantime.

Violence in this context means any unlawful touching, though there is some debate over whether the touching must also be hostile.

The transmission system must include a means of television channel selection.

Cayley believed that the drag on a flying machine must be counteracted by a means of propulsion in order for level flight to occur.

This means that new acceptance tests must be created for each iteration or the development team will report zero progress.

As nothing cannot be known by any means or method it must mean, in the context of the question, that a specific named object is present or not present in the observer's experience of a set of objects, conditions for which English uses " is " or " is not.

The main use of the plate appearance statistic is in determining a player's eligibility for leadership in some offensive statistical categories, notably batting average ; currently, a player must have 3. 1 PAs per game scheduled to qualify for the batting title ( for the 162-game schedule, that means 502 PAs ).

The bicycle is the most efficient human-powered means of transportation in terms of energy a person must expend to travel a given distance.

To sum to zero, the force of the water must point oppositely to the sum of the centrifugal and gravity forces, which means the surface of the water must adjust so its normal points in this direction.

In the chapter, Nicodemus is puzzled and asks Jesus what he means by saying that " Ye must be born again ".

Utilitarian theories, on the other hand, must answer the charge that ends do not justify the means.

It should be noted that calculated fatality rates based on distance for bicycling ( as well as for walking ) can have an exceptionally large margin of error, since there are generally no annual registrations or odometers required for bicycles ( as there are with motor vehicles ), and this means the distance traveled must be estimated.
