Additionally the pump itself will make many safety checks throughout the day, in some cases up to 4, 000, 000 and may have a second microprocessor dedicated to this.

Then, after the pump energy stored in the laser medium has approached the maximum possible level, the introduced loss mechanism ( often an electro-or acousto-optical element ) is rapidly removed ( or that occurs by itself in a passive device ), allowing lasing to begin which rapidly obtains the stored energy in the gain medium.

Another method of achieving pulsed laser operation is to pump the laser material with a source that is itself pulsed, either through electronic charging in the case of flash lamps, or another laser which is already pulsed.

Strictly the term refers to the pump itself, which is normally manually operated, though electrically powered and gas powered pumps are occasionally used.

The throat itself is very muscular, serving to absorb the partially liquified food and to pump it, via the oesophagus, which forms the rear part of the front intestine, into the central intestine.

The motto Viva La Russell has become a rallying cry for the protection of the pump and emblematic of the town itself.

The animal will pump itself up to expand the new shell to maximal size, then let it harden.

There is some evidence that proton pump inhibitors are a risk factor for C. difficile infection and pseudomembranous colitis, but others question whether this is a false association or statistical artifact ( increased PPI use is itself a marker of increased age and co-morbid illness ).

In this, the pump source ( energy source ) for the laser is itself modulated, effectively turning the laser on and off to produce pulses.

Typically, the pump source is itself another mode-locked laser.

The CPB pump itself is often referred to as a heart – lung machine or " the pump ".

Another benefit of an in-tank mounted fuel pump is that a suction pump at the engine could suck in air through a ( difficult to diagnose ) faulty hose connection, while a leaking connection in a pressure line will show itself immediately.

Placing the pump in the tank puts the component least likely to handle gasoline vapor well ( the pump itself ) farthest from the engine, submersed in cool liquid.

The fuel pump by itself is a relatively inexpensive part.

Originally produced as a tougher, stronger and more improved version of the Winchester 1893, itself a takeoff on the early Spencer pump gun, the 1897 was identical to its forerunner, except that the receiver was thicker and allowed for use of smokeless powder shells, which were not common at the time.

The gun itself is classified as a slide action pump shotgun.

The heat pump itself can be improved by increasing the size of the internal heat exchangers relative to the power of the compressor, and to reduce the system's internal temperature gap over the compressor.

Although it weighs almost nothing and has no moving parts, a getter is itself a vacuum pump.

The gas generator itself was welded to the fuel pump turbine manifold, making it an integral part of the fuel turbopump assembly.

The water pump is driven from the timing belt, with the water pump housing cast partially into the engine block itself.

The Flite-King Trophy ( beginning at just over $85 ) is a pump gun in 12 or 16.

A BTU is a unit of heat, and the BTU rating of a conditioner refers to how much heat your machine can pump out of your house in an hour.

Amphibians breathe by means of a pump action in which air is first drawn into the buccopharyngeal region through the nostrils.

An oil pipeline to pump Iranian oil products is also in the planning stages.

He is credited with designing innovative machines, including siege engines and the screw pump that bears his name.

It is primarily for this reason that the histamine H2 antagonists including cimetidine ( Tagamet ), famotidine ( Pepcid ), and ranitidine ( Zantac ), and the proton pump inhibitor ( PPI ) omeprazole ( Prilosec ) were made OTC.

(" Miracle Song ") It is soon revealed to Cora that the miracle is a fake, controlled by a pump inside the rock.

If enough electric power is available, cooling can be provided by conventional air conditioning using a heat pump.

The primary responsibility of the heart is to pump blood around the body.

The heart is a muscle that squeezes blood and functions like a pump.

The mechanical part of the heart is centered on the fluidic movement of blood and the functionality of the heart as a pump.

After decades of neglect and damage from wartime, Cambodia's rail network is currently being reconstructed as part of the Trans-Asian Railway project with modern trains replacing the current open-access system of " bamboo trains ", homemade bamboo mats powered by go-kart or water pump engines.

This role as a sink for CO < sub > 2 </ sub > is driven by two processes, the solubility pump and the biological pump .< ref > The former is primarily a function of differential CO < sub > 2 </ sub > solubility in seawater and the thermohaline circulation, while the latter is the sum of a series of biological processes that transport carbon ( in organic and inorganic forms ) from the surface euphotic zone to the ocean's interior.

A small fraction of the organic carbon transported by the biological pump to the seafloor is buried in anoxic conditions under sediments and ultimately forms fossil fuels such as oil and natural gas.

The solubility pump is the primary mechanism driving this, with the biological pump playing a negligible role.

In 1901, with a better vacuum pump, Pyotr Lebedev showed that in fact, the radiometer only works when there is low pressure gas in the bulb, and the vanes stay motionless in a hard vacuum.

A second membrane ion exchanger, NCX, is responsible for ' pumping ' calcium ions out of the cell and sodium ions in ( 3Na / Ca ); raised intracellular sodium levels inhibit this pump, so calcium ions are not extruded and will also begin to build up inside the cell.

This dose, however, is less in those with lowered gastric acidity ( for instance those using proton pump inhibitors ).

The features that make the diffusion pump attractive for high and ultra-high vacuum use are its high pumping speed for all gases and low cost per unit pumping speed when compared with other types of pump used in the same vacuum range.

Surgical interventions for IC / BPS include transurethral fulguration and resection of ulcers, using electricity / laser ; bladder denervation, where some of the nerves to the bladder are cut ( Modified Ingelman-Sundberg Procedure ); bladder augmentation ; bladder removal ( cystectomy ); electrical nerve stimulation, similar to TENS, where an electrical unit is implanted in the body and provides continuous or intermittent electrical pulses to the affected areas ( Interstim ); spinal cord stimulation ( SCS ), where an electrical unit is implanted that provides electrical stimulation to the spinal cord, interfering with pain reception to the brain ( ANS / Advanced Neuromodulation Systems spinal Cord Stimulator ); and the implantation of the intrathecal pain pump, where very small amounts of medication, like morphine sulfate, dilaudid, or baclofen are released into the cerebrospinal fluid via a catheter stemming from the small electrical pump, requiring only about 1 / 100 to 1 / 300 the amount of medication needed orally for the same therapeutic benefit, but with significantly fewer side effects.

* Pumping speed refers to the volume flow rate of a pump at its inlet, often measured in volume per unit of time.

At a constant temperature, throughput is proportional to the number of molecules being pumped per unit time, and therefore to the mass flow rate of the pump.

His Captain gives him the clearance, and provides him with an Ithaca 37 pump action 12 gauge shotgun, and an unmarked 1988 Chevrolet Caprice tactical unit.

Note that an air source heat pump is more efficient in hotter climates than cooler ones, so when the weather is much warmer the unit will perform with a higher COP ( as it has less work to do ).

By contrast, a waterjet unit delivers a high-pressure " push " from the stern of a vessel by accelerating a volume of water as it passes through a specialised pump mounted above the waterline inside the boat hull.

Depending on the engine, this might include high pressure injection pumps, pump injectors ( also called unit injectors ) and fuel injectors. Older diesel Mercedes are popular for running on biodiesel.

Following this, Beamont lit a single reheat unit only ( because of problems with the other engine's reheat fuel pump ), with the result that the aircraft accelerated away from the chase Lightning flown by Wing Commander James " Jimmy " Dell, who had to catch up using reheat on both engines.

The hydraulic pump, attached to the tool or as a separate unit, powers a piston that pushes the blades apart with great force and spreads the seam.

The most commonly used source is a separate power unit, a small petrol ( gasoline ) engine connected to a hydraulic pump.

Cars with electronic fuel injection have an electronic control unit ( ECU ) and this may be programmed with safety logic that will shut the electric fuel pump off, even if the engine is running.

The fuel sending unit assembly may be a combination of the electric fuel pump, the filter, the strainer, and the electronic device used to measure the amount of fuel in the tank via a float attached to a sensor which sends data to the dash-mounted fuel gauge.

A sphygmomanometer consists of an inflatable cuff, a measuring unit ( the mercury manometer, or aneroid gauge ), and a mechanism for inflation which may be a manually operated bulb and valve or a pump operated electrically.

A pumpjack ( also called nodding donkey, pumping unit, horsehead pump, rocking horse, beam pump, dinosaur, sucker rod pump ( SRP ), grasshopper pump, thirsty bird, jack pump, or popping johnny ) is the overground drive for a reciprocating piston pump in an oil well.
