Argon was also blown at low velocities ( mass flow rate Af ) through a tube coaxial with the cathode as an additional precaution against contamination of the arc by air.

For each mass flow rate the arc voltage was measured.

They showed no marked dependence on the flow rate within the accuracy of these measurements.

The flow rate remained relatively constant during the winter months as shown in Table 1.

In this way, amperes can be viewed as a flow rate, i. e. number of particles ( charged ) transiting per unit time, and coulombs simply as the number of particles.

Rather than a definition in terms of the force between two current-carrying wires, it has been proposed to define the ampere in terms of the rate of flow of elementary charges.

As the body prepares to deal with a threat, blood pressure, heart rate, perspiration, blood flow to the major muscle groups are increased, while immune and digestive functions are inhibited ( the fight or flight response ).

Renal blood flow may be affected by angiotensin II because it vasoconstricts the efferent arterioles of the glomeruli of the kidney, thereby increasing glomerular filtration rate ( GFR ).

In vitro, they dilate the coronary and peripheral arteries and have negative inotropic and chronotropic effects-decreasing afterload, improving myocardial efficiency, reducing heart rate and improving coronary blood flow.

The viscous dissipation function governs the rate at which mechanical energy of the flow is converted to heat.

The flow rate of the Arno is irregular.

* Volumetric flow rate

This approach is conveniently applied in the study of fluid flow where the kinematic property of greatest interest is the rate at which change is taking place rather than the shape of the body of fluid at a reference time.

The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second.

In order for there to be a net flow of charge, the particles must also move together with an average drift rate.

By studying how quickly the reagent species disappears in the presence of differing concentrations of a ( usually stable ) co-reagent species the reaction rate constant at the low temperature of the CRESU flow can be determined.

It involves heating the sample at a controlled rate and recording the heat flow either into or from the specimen.

The most widely used method of discounting is exponential discounting, which values future cash flows as " how much money would have to be invested currently, at a given rate of return, to yield the cash flow in future.

where FV ( t ) is now the rate of cash flow, and λ

* Groundwater discharge, the volumetric flow rate of groundwater through an aquifer

Production is a flow and thus a rate of output per period of time.

The increased flow of water through local waterways also causes a large increase in the rate of bank erosion.

Note that the previous expression holds true only if the kinetic energy flow rate is conserved between system inlet and outlet.

The headwaters of the Wolf River meander and braid their way north and west across northern Benton County from Baker's Pond, the river's source spring ( highest origin of continuous flow ) in the Holly Springs National Forest approximately one mile southwest of where U. S. Highway 72 passes into Tippah County, Mississippi.

Local bus flow was controlled by traffic lights, and routes ( such as the number 72 ) were required to convert from double-decker buses to smaller single-deckers to reduce the load on the bridge.

In the study, the subjects ( 27 people ages 18 to 72 ) drank a cocoa drink containing 900 milligrams of flavonols every day, which resulted in an improvement in blood flow and the function of endothelial cells that line blood vessels.

According to the tantras there are 72, 000 or more such channels or networks through which the stimuli flow like an electric current from one point to another.

The argon flow through the porous anode was varied systematically between Af and Af.

Normally Hague wasted no words, but now he found himself unable to stop their flow although he knew Kodyke was aware of all he said.

At once my ears were drowned by a flow of what I took to be Spanish, but -- the driver's white teeth flashing at me, the road wildly veering beyond his glistening hair, beyond his gesticulating bottle -- it could have been the purest Oxford English I was half hearing ; ;

It was with the assistance of one of the members of this expedition, Lauritz Esmarch, that Oersted succeeded in producing light by creating an electric discharge in mercury vapor through which an electric current was made to flow.

The dependence of the arc voltage upon the mass flow velocity of the transpirating gas was investigated for various arc lengths and currents between 100 Amp and 200 Aj.

This small pore size was required to ensure uniformity of the flow leaving the anode.

The argon flow from commercial bottles was regulated by a pressure regulator and measured with a gas flow rator.

The lower limit was determined by the fact that for smaller flow rates the arc started to strike to the anode holder instead of to the porous graphite plug and that it became highly unstable.

For the low-temperature measurements the sample was cooled by a cold nitrogen gas flow method similar to that of Andrew and Eades.

As early as 1913 Ghoreyeb and Karsner demonstrated with perfusion studies in dogs that bronchial artery flow would remain constant at a certain low level when pressure was maintained in the pulmonary artery and vein, but that increases in bronchial artery flow would occur in response to a relative drop in pulmonary artery pressure.

It is true that, initially, the task was to remove restrictions that, it was thought, inhibited the free flow of money, goods, and labor ; ;

When it was all arranged to fit, and not to interrupt the lengthwise flow of movement in the frieze, the cartoons were tried in place.

The sewage flow into the treatment plant was metered and continuously recorded on 24-hr. charts.

It was hoped that to this post would flow a large quantity of furs from the west, principally down the Arkansas River.

`` There was only one power control -- a valve to adjust the fuel flow.

Django Reinhardt, the ill-fated gypsy, was a true artist, one who demonstrated conclusively the power of art to renew itself and flow into many channels.

Peter B. deMenocal, has shown there was an influence of the North Atlantic Oscillation on the stream flow of the Tigris and Euphrates at this time, which led to the collapse of the Akkadian Empire ".

This use of ATP provided automatic flow control ; each end could only send data to the other end if there was an outstanding ATP request to respond to.
