Since the speed of sound varies with temperature, and is virtually stable with pressure change, sonic anemometers are also used as thermometers.

Since the pressure difference determines the vertical position of the float this is a measured of the wind speed.

Since helium remains a liquid even at absolute zero at atmospheric pressure, it has only a boiling point, and not a melting point, in conventional presentations.

Since Jews believe that one need not be a Jew to approach God, there is no religious pressure to convert non-Jews to their faith.

Since these properties are often used as reference values it is very common to quote them for a standardized set of environmental parameters, or standard conditions, which is typically a temperature of and a pressure of either or.

Since the flow speed is zero at these points, by Bernoulli's principle the static pressure at these points is at a maximum.

Since dynamic pressure is referenced to static pressure, it is neither gauge nor absolute ; it is a differential pressure.

Since the gaseous molecule density is proportional to the pressure, the pressure is estimated by measuring the ion current.

Since the election of George W. Bush as the President of the United States, North Korea has faced renewed external pressure over its nuclear program, reducing the prospect of international economic assistance.

Since Major's election as leader, Kinnock spent the end of 1990 and most of 1991 putting pressure on Major to hold the election that year, but Major had held out and insisted that there would be no general election in 1991.

Since the 9 / 11 attacks in 2001, there has been mounting pressure to reform and modernize the royal family's rule, an agenda championed by King Abdullah both before and after his accession in 2005.

Since atmospheric pressure reduces as the aircraft climbs, power drops as a function of altitude in normally aspirated engines.

Since it is in the gas phase, the amount of vapor present is quantified by the partial pressure of the gas.

* Since the establishment of its presidencies in 1689, the British East India Company has been under constant pressure from traders who are not members of the company and are not licensed by the Crown to trade.

Since intensity is proportional to the square of pressure amplitude, this is just a variation on the inverse-square law.

Since temperature in principle also depends on altitude, one needs a second equation to determine the pressure as a function of height, as discussed in the next section.

Since 2000, the spawning stock has increased quite quickly, helped by low fishing pressure.

Since the time of McCarthy, the word McCarthyism has entered American speech as a general term for a variety of practices: aggressively questioning a person's patriotism, making poorly supported accusations, using accusations of disloyalty to pressure a person to adhere to conformist politics or to discredit an opponent, subverting civil rights in the name of national security, and the use of demagoguery are all often referred to as McCarthyism.

For most bands and most small-to mid-size venues ( e. g., nightclubs and bars ), standard bass guitar speaker enclosures or keyboard amplifiers will provide sufficient sound pressure levels for onstage monitoring. Since a regular electric bass has a low " E " ( 41 Hz ) as its lowest note, most standard bass guitar cabinets are only designed with a range that goes down to about 40 Hz.

Since oral decongestant drugs raise blood pressure levels, individuals with hypertension are advised to avoid them.

Since Bragg's army was under increasing pressure from Rosecrans outside of Chattanooga, Lee and President Davis agreed to the request on September 5.

Since quartz is very strong, the gas pressure can be higher, which reduces the rate of evaporation of the filament, permitting it to run a higher temperature ( and so luminous efficacy ) for the same average life.

Since the gradient coils are within the bore of the scanner, there are large forces between them and the main field coils, producing most of the noise that is heard during operation.

Since the pheromone is carried by the wind, males tend to travel up the concentration gradient, i. e., toward the source.

: Since 2008, there has been discussion among professional users of SVG that either gradient meshes or preferably diffusion curves could usefully be added to the SVG specification.

Since it does not ordinarily pass through cell membranes, protein pores in cell membranes are used to provide a channel through which it can be ' pumped ' -- an activity which requires energy if done against a concentration gradient.

Since high pressure areas usually migrate east, changing the pressure gradient in southern California to the northeast, it is common for " sundowner " wind events to precede Santa Ana events by a day or two.

Since the gradient of a function is perpendicular to the contour lines, this is the same as saying that the gradients of f and g are parallel.

Since this carrier enzyme ( Na < sup >+</ sup >- Ca < sup > 2 +</ sup > translocator ) uses the Na gradient generated by the Na < sup >+</ sup >- K < sup >+</ sup > pump to remove Ca < sup > 2 +</ sup > from the intracellular space, slowing down the Na < sup >+</ sup >- K < sup >+</ sup > pump results in a permanently elevated Ca < sup > 2 +</ sup > level in the muscle, which may be the mechanism of the long-term inotropic effect of cardiac glycosides such as digoxin.

The set of ( p < sub > i </ sub >, n < sub > i </ sub >) is thus a sampling of a continuous vector field V. The implicit function f is found by integrating the vector field V. Since not every vector field is the gradient of a function, the problem may or may not have a solution: the necessary and sufficient condition for a smooth vector field V to be the gradient of a function f is that the curl of V must be identically zero.

Since the fluid in the inner part of the boundary layer is relatively slower, it is more greatly affected by the increasing pressure gradient.

Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes " down the concentration gradient " ( compared with active transport, which often moves material from area of low concentration to area of higher concentration, and therefore referred to as moving the material " against the concentration gradient ").

Since the curl of v is zero, it follows that v can be expressed as the gradient of a scalar potential ( see irrotational field ) φ:

Since the gradient varies along the route, the floor of each car is never quite level, and slopes slightly " uphill " or " downhill " depending on the location.

Since the normal left ventricular diastolic pressures is about 5 mmHg, a pressure gradient across the mitral valve of 20 mmHg due to severe mitral stenosis will cause a left atrial pressure of about 25 mmHg.

Since the field is the gradient of the electrostatic potential, another way of saying this is that in electrostatics, the potential ( voltage ) throughout a conductive object is constant.

Since the force fields are related to their potentials by the gradient:

Since the direction of the force is dependent on field gradient rather than field direction, DEP will occur in AC as well as DC electric fields ; polarization ( and hence the direction of the force ) will depend on the relative polarizabilities of particle and medium.

Since the head drops are uniform by construction, the gradient is inversely proportional to the size of the blocks.

Since a liquid with a high surface tension pulls more strongly on the surrounding liquid than one with a low surface tension, the presence of a gradient in surface tension will naturally cause the liquid to flow away from regions of low surface tension.

Since the source is located at the end of the solenoid which generates the main LaPD background field, there is a gradient in the magnetic field within the cavity.

Since in the open air, as many engines as needed can be added to a train to overcome a steep gradient, a better solution would have been to have a level tunnel from " New Tye " ( West ) to Cascade Tunnel Station ( West ), with a 2. 6 mile stretch of say 4 % gradient ( 1 in 25 ) on the western approaches from say Windy Point Tunnel.
