Its heart, which can weigh more than and measures about long, must generate approximately double the blood pressure required for a human to maintain blood flow to the brain.

Some combination or hybrid bits combine direct pressure and leverage, such as the Kimblewick or Kimberwicke, which adds slight leverage to a two-rein design that resembles a snaffle ; and the four rein designs such as the single mouthpiece Pelham bit and the double bridle, which places a curb and a snaffle bit simultaneously in the horse's mouth.

Custard is usually cooked in a double boiler ( bain-marie ), or heated very gently in a saucepan on a stove, though custard can also be steamed, baked in the oven with or without a water bath, or even cooked in a pressure cooker.

A Non-simultaneous double squeeze, in the card game of bridge, is a double squeeze in which the pressure is not applied to both opponents at the same trick.

This has led to the development of the balanced poppet or double beat valve, in which two valve plugs ride on a common stem, with the pressure on one plug largely balancing the pressure on the other.

This means that changing to particles that are half as big, keeping the size of the column the same, will double the performance, but increase the required pressure by a factor of four.

The modern oil fired thermic fluid heater consists of a double coil, three pass construction and fitted with modulated pressure jet system.

The lifter pressure and position, roll and chuck designs, tooling wear, and bearing wear all contribute to a good double seam.

As an example of the possible magnitude of the pressure effect, some organic reactions were shown to double the reaction rate when the pressure was increased from atmospheric ( 0. 1 MPa ) to 50 MPa ( which gives

Unlike a parabolic profile flow generated from a pressure differential, a plug flow ’ s velocity profile is approximately planar, with slight variation near the electric double layer.

Because of their higher gold content, and greater striking pressure, the coins were 27 mm wide and 4 mm deep ( the same diameter as a gold eagle ), rather than the 34 by 2 usual for double eagles and bullion coins.

The advantage of a double circulatory system is that blood can be pumped simultaneously into low pressure / compliance ( pulmonary / right ) and high pressure / compliance ( systemic / left ) loops.

The open roll ( or " double-stroke roll ") is played with double strokes alternating between the left and right hands ; the closed roll or multiple-bounce roll is produced by applying slightly more pressure to the fulcrum upon impact which allows for the stick to bounce many times on the drum head.

However, the double wall design will bow-in under excessive water pressure.

Others have an all-metal support, while larger brayers have a double handle to apply maximum pressure.

* As the pressure of his double life began to mount, he started to drink heavily and became an alcoholic

The double check valve assembly is suitable for prevention of back pressure and back siphonage, but is not suitable for high hazard applications.

Others ( glass-glass ) are made with a double layer of glass fused together at one or both ends with a vacuum between the layers ( like a vacuum bottle or flask ), with the absorber and heat pipe contained at normal atmospheric pressure.

These propellant mixtures have reduced flash and flame temperature without sacrificing chamber pressure compared to single and double base propellants, albeit at the cost of more smoke.

Some luxury options featured on the E32 included integrated telephone and fax machines, a wine cooler, double glazing, traction control system, and a system that automatically increased spring pressure on the windscreen wipers, to keep them firmly pressed on the glass at Motorway speeds.

His counterpart, in a state of paranoia, claims the double threatens his and the very cosmos ' existence.

For example, if black tries to attack with an unlinked peg at O15, white could respond with N16 which threatens to double link at P15.

If white continues the attack with G16 then black has H16 which threatens to double link at J15.

The bottom left is a mirror image, and shows the result after 1. D21 2. E21 3. F22 * which threatens to cut through black's short setup with a double link at E20.

They even accept the `` double standard '' of sex morality in a double sense, i.e., both sexes agree that standards for men differ from standards for women, and women apply to both sexes a standard different from that held by men.

This conclusion is dependent on the assumption that traditional sex mores will continue to sanction both premarital chastity as the `` ideal '', and the double standard holding females primarily responsible for preserving the ideal.

Then Robinson slammed a long double to left center to score both runners.

He is talking about double effects, of which the specific action causes directly the one and indirectly the other, but causes both ; ;

It is a violation to move without dribbling the ball ( travelling ), to carry it, or to hold the ball with both hands then resume dribbling ( double dribble ).

Need for presence of double coincidence of wants: For barter to occur between two people, both would need to have what the other wants.

4-Both cells synthesize a complementary strand to produce a double stranded circular plasmid and also reproduce pili ; both cells are now viable donors.

Where both sides are bidding, 4NT is likely to be a conventional takeout asking partner to help choose one of two or three suits, similar to a lower-level takeout double or cue reply to a double.

There is no consensus on some terms describing carbon nanotubes in scientific literature: both "- wall " and "- walled " are being used in combination with " single ", " double ", " triple " or " multi ", and the letter C is often omitted in the abbreviation ; for example, multi-walled carbon nanotube ( MWNT ).

In the case of SWNT, covalent functionalization will break some C = C double bonds, leaving " holes " in the structure on the nanotube and, thus, modifying both its mechanical and electrical properties.

The other three are < sup > 106 </ sup > Cd, < sup > 108 </ sup > Cd ( both double electron capture ), and < sup > 114 </ sup > Cd ( double beta decay ); only lower limits on their half-life times have been set.

Competition typically results in a double negative — that is both species lose in the interaction.

In turn, when B is replaced with a list of attached atoms, A itself is excluded in accordance with the general principle of not doubling back along a bond that has just been followed, but a ghost atom for A is included so that the double bond is properly represented from both ends.

If both high priority substituents are on the same side of the double bond, i. e. in the cis configuration, then the stereoisomer is assigned a Z or Zusammen configuration.

This is both an example of rhyming slang and of a sexual double entendre.

In a letter published in The Times newspaper on 9 April 1983, Geoffrey Crawley explained the discrepancy by suggesting that the photograph was " an unintended double exposure of fairy cutouts in the grass ", and thus " both ladies can be quite sincere in believing that they each took it ".

Since both the noun and enclitic were declined, this led to " double declension ".

In double trigger designs, it is often possible to pull both triggers at once, firing both barrels simultaneously, though this is generally not recommended as it doubles the recoil, battering both shooter and shotgun.
