File: Blaise pascal. jpg | Blaise Pascal ( 1623-1662 ): experimented with fluids, formulated Pascal's law in the 1650s stating that the pressure applied to a fluid taken in a closed container is transmitted with equal force throughout the container, proved that air has weight and that air pressure can produce a vacuum, namesake of the unit of pressure: the pascal ( Pa )

A mirepoix ( ; ) can be a combination of celery ( either common pascal celery or celeriac ), onions, and carrots.

Units for measuring vascular resistance are dyn · s · cm < sup >− 5 </ sup >, pascal seconds per cubic metre ( Pa · s / m³ ) or, for ease of deriving it by pressure ( measured in mmHg ) and cardiac output ( measured in l / min ), it can be given in mmHg · min / l.

The absolute threshold relates to the sound that can just be heard by the organism. The threshold of hearing is generally reported as the RMS sound pressure of 20 µPa ( micropascals ) = 2 × 10 < sup >− 5 </ sup > pascal ( Pa ).

The effect begins to be seen at partial vacuum pressures of a few torr ( several hundred pascals ), reaches a peak at around 10 < sup >− 2 </ sup > torr ( 1 pascal ) and has disappeared by the time the vacuum reaches 10 < sup >− 6 </ sup > torr ( 10 < sup >− 4 </ sup > pascal ) ( see explanations note 1 ).

While pressure may be measured in any unit of force divided by any unit of area, the SI unit of pressure ( the newton per square metre ) is called the pascal ( Pa ) after the seventeenth-century philosopher and scientist Blaise Pascal.

This allows the general behaviour of old style pascal strings to be preserved whilst eliminating the cost of copying the string on every assignment.

This symbol coincides with that for the pascal without a multiplier prefix, though both are infrequently used and context will normally be sufficient to distinguish time from pressure values.

where P is the absolute pressure of the gas measured in Pascals ; V is the volume ( in this equation the volume is expressed in meters cubed as pascal times cubic meter equals one Joule ); N is the number of particles in the gas ; k is Boltzmann's constant relating temperature and energy ; and T is the absolute temperature.

: The sensitivity of a microphone is usually expressed as the sound field strength in decibels ( dB ) relative to 1 V / Pa ( Pa = N / m < sup > 2 </ sup >) or as the transfer factor in millivolts per pascal ( mV / Pa ) into an open circuit or into a 1 kilohm load.

In SI units, torque density is expressed in joules per cubic metre or equivalently newton-metres per cubic metre ( though dimensionally equivalent to the pascal, that is usually not used for this purpose ).

Shear modulus ' derived SI unit is the pascal ( Pa ), although it is usually expressed in gigapascals ( GPa ) or in thousands of pounds per square inch ( kpsi ).

In the SI system, the unit is the pascal ( Pa ) ( or a multiple thereof, often megapascals ( MPa ), using the mega-prefix ); or, equivalently to pascals, newtons per square metre ( N / m² ).

The bar is defined using the SI unit pascal, namely: ≡.

Thus, for example, the CGS unit of pressure, barye, is related to the CGS base units of length, mass, and time in the same way as the SI unit of pressure, pascal, is related to the SI base units of length, mass, and time:

The SI unit for pressure is the pascal ( Pa ), equal to one newton per square metre ( N · m < sup >− 2 </ sup > or kg · m < sup >− 1 </ sup >· s < sup >− 2 </ sup >).

The SI unit for pressure is the pascal ( Pa ), equal to one newton per square meter ( N / m < sup > 2 </ sup > or kg · m < sup >− 1 </ sup >· s < sup >− 2 </ sup >).

The SI unit of pressure is the pascal ( symbol: Pa ), defined as one newton per square metre.

The International System of Units ( SI ) recognizes pressure as a derived unit with the dimension of force per area and designates the pascal ( Pa ) as its standard unit.

The pascal ( symbol: Pa ) is the SI derived unit of pressure, internal pressure, stress, Young's modulus and tensile strength, named after the French mathematician, physicist, inventor, writer, and philosopher Blaise Pascal.

The name pascal was adopted for the SI unit newton per square metre by the 14th CGPM in 1971.

The pascal is also equivalent to the SI unit of energy density, J / m < sup > 3 </ sup >.

* Decipascal ( dPa ), an SI unit equivalent to one tenth of a pascal

The SI unit of modulus of elasticity ( E, or less commonly Y ) is the pascal ( Pa or N / m² or m < sup >− 1 </ sup >· kg · s < sup >− 2 </ sup >).

* p is pressure ( SI unit: pascal )

In general, the SI unit of stress is the pascal, where 1 Pa = 1 N / m².

The SI unit for sound pressure p is the pascal ( symbol: Pa ).

In SI units, the unit is converted to the SI derived unit pascal ( Pa ), which is defined as one newton per square meter ( N / m < sup > 2 </ sup >).

Common multiple units of the pascal are the hectopascal ( 1 hPa ≡ 100 Pa ), kilopascal ( 1 kPa ≡ 1000 Pa ), and megapascal ( 1 MPa ≡ 1, 000, 000 Pa ).

Its base unit is the pascal.

`` That is, if we can be sure this is Colcord's money '' --

It'll probably be at least an hour or two before I can check back with you.

Even as I said it I realized that an education can be invaluable.

Within their confines, moreover, technological and industrial growth has proceeded at an accelerated pace, thus increasing the cornucopia from which material wants can be satisfied.

And no messages can be transmitted on these circuits until senders and receivers authenticate in advance, by special codes, that the messages actually come from their purported sources.

Additional codes can be used to challenge and counterchallenge the authentications.

Nobody can be absolutely certain of the answers.

All can be connected with the gold circuit from their homes.

The box is internally wired so the door can never be opened without setting off a screeching klaxon ( `` It's real obnoxious '' ).

Unless all gadgets are properly operated -- and the wires and seals from the handles removed first -- no damage can be done.

I do not know if such a way of life can come to be a self-conscious challenge, but I suspect that it can.

As his disciples boast, even though his emphasis is elsewhere, Faulkner does show his awareness of the changing order of the South quite keenly, as can be proven by a quick recalling of his Sartoris and Snopes families.

An order can be chanced rather than chosen, and this approach produces an experience that is `` free and discovered rather than bound and remembered ''.

And any sequence can not only change its positions in the work but can even be eliminated from it altogether.

When it comes to this, I shall prefer emigrating to some country where they make no pretence of loving liberty -- to Russia, for instance, where despotism can be taken pure, without the base alloy of hypocrisy '' ( His emphasis )

Something of this can be learned from `` The Way To The Churchyard '' ( 1901 ), an anecdote about an old failure whose fit of anger at a passing cyclist causes him to die of a stroke or seizure.

Similarly experience itself can be conventionalized so that people react to certain preconceived clues for behavior without awareness of the vitality of their experiential field.

When words can be used in a more fresh and primitive way so that they strike with the force of sights and sounds, when tones of sound and colors of paint and the carven shape all strike the sensibilities with an undeniable force of data in and of themselves, compelling the observer into an attitude of attention, all this imitates the way experience itself in its deepest character strikes upon the door of consciousness and clamors for entrance.

it can be changed ; ;

You've already sent your daughter to Miss X's select academy for girls and your son to Mr. Y's select academy for boys, and you can be as liberal as you please with strict impunity.

In scope and power it can only be compared to Tolstoy's War And Peace.

However, for convenience we will stick to the idea that information can be classified according to Table 1.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.
