Classical Variation ( C48 ), 0 – 1 Morphy's queen sacrifice transforms his positional pressure into a decisive attack on Paulsen's king.

* 4. g3-The Fianchetto Variation resembles the Catalan System, where White fianchettoes his king's bishop to put pressure on the centre squares from the flank.

It was generally thought that an early Nf3 was weak in the Exchange Variation because it allowed Black too much pressure on the centre with ... Bg4.

This usually transposes to positions arising from 3 ... Nf6, and has the advantage, from Black's standpoint, of avoiding the insidious pressure of the main lines in the Exchange Variation arising after 3 ... Nf6 4 cxd5 exd5 5 Bg5 with an annoying pin.

The Variation of the Spinebuster the attacking Wrestler grabs the opponent around the waist, lifts him or her up, and tosses him or her forward without landing on the top of his or her opponent.

He presented this ' provisional hypothesis ' in his 1868 work The Variation of Animals and Plants under Domestication and felt that it brought ' together a multitude of facts which are at present left disconnected by any efficient cause '.

The album mixed in a ballad by Greg Lake ( The Sage ), a Blues Variation section by Emerson and many instances of heavily electronic and synthesised interpretations of Mussorgsky's work ( although the opening promenade was played faithfully on a Hammond organ ).

The previous supports Kirschner and Gerhart's theory of Facilitated Variation, which states that morphological evolutionary novelty is generated by regulatory changes in various members of a large set of conserved mechanisms of development and physiology.

* Boris Spassky vs Efim Geller, Sukhumi Candidates ' match 1968, game 6, Sicilian Defence, Closed Variation ( B25 ), 1 – 0 One of three beautiful wins by Spassky over Geller in this match using the same variation, which is one of Spassky's favorites.

To correctly record a Chess960 game in PGN, an additional " Variant " tag ( not " Variation " tag, which has a different meaning ) must be used to identify the rules ; the rule named " Fischerandom " is accepted by many chess programs as identifying Chess960, though " Chess960 " should be accepted as well.

* François André Philidor vs NN, Unknown 1749, Bishop's Opening: Boi Variation ( C23 ), 1 – 0 This game — possibly a composition by Philidor — demonstrates the value of passed pawns

The fugue of Variation 32 is set apart by its foreign key, E-flat major.

This forces Black to retreat the bishop to e7 or capture on c3, which transposes to a line of the Sämisch Variation long considered good for White because he will undouble his pawns at some point by playing cxd5, eliminating the weak pawn on c4, then prepare the e4 pawn break, backed by the bishop pair, which will gain force in the more open type of position which will ensue.

Black also has two rare alternatives on his eighth move worth mentioning: 8 ... Qe7 intending ... Rd8 is the Smyslov Variation, invented by former World Champion Vasily Smyslov, and 8 ... Bd7 followed by ... Bc6 is the Bronstein Variation, the brainchild of two-time world championship finalist David Bronstein.

* The Larsen Variation ( named after GM Bent Larsen ) can be reached by either 7 ... dxc4 8. Bxc4 Nc6 9. a3 Ba5 or 7 ... Nc6 8. a3 dxc4 9. Bxc4 Ba5, but the latter move order gives White the extra option of 9. axb4.

* The Averbakh Variation ( 7 ... Nbd7 ) was popularized by Grandmasters Viacheslav Ragozin and Yuri Averbakh.

* 5. Bd3 d5 6. Ne2 and the closely related variant 5. Bd3 d5 6. cxd5 exd5 7. Ne2 were collectively dubbed the " Modern Variation " by FM Carsten Hansen in his book on the Rubinstein Nimzo-Indian.

* 5. Bd3 Nc6 6. Nf3 ( 6. Ne2 will likely transpose to the Modern Variation ) 6 ... Bxc3 + 7. bxc3 d6 is the Hübner Variation, popularized by GM Robert Hübner in the late 1960s and ' 70s and utilised by Bobby Fischer in his world championship match with Boris Spassky in 1972 with great effect in game 5.

Variation of parameters extends to linear partial differential equations as well, specifically to inhomogeneous problems for linear evolution equations like the heat equation, wave equation, and vibrating plate equation.

Most traffic classes also introduce the concept of Cell Delay Variation Tolerance ( CDVT ), which defines the " clumping " of cells in time.

He was also vital in the development of two important systems in the French Defence, the Winawer Variation ( in some places called the Nimzowitsch Variation ; its moves are 1. e4 e6 2. d4 d5 3. Nc3 Bb4 ) and the Advance Variation ( 1. e4 e6 2. d4 d5 3. e5 ).

He also pioneered two provocative variations of the Sicilian Defence: the Nimzowitsch Variation, 1. e4 c5 2. Nf3 Nf6, which invites 3. e5 Nd5 ( similar to Alekhine's Defence ) and 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 d5?!

In the most confidential whispers ambassadors told of techniques they had tried to bring Rooney around -- friendly persuasion, groveling abasement, pressure subtly exerted through other powerful congressmen, tales of heartbreak and penury among a threadbare diplomatic corps.

He picked up another credited Weil conjecture, around 1967, which later under pressure from Serge Lang ( resp.

The high pressure air below the lower surface of the wing moves around the wingtip towards the lower-pressure region on the upper surface, creating the vortex.

These fish can still, however, find their way around by means of their lateral lines, which are highly sensitive to fluctuating water pressure.

In 1857, German physicist and glassblower Heinrich Geissler sucked even more air out with an improved pump, to a pressure of around 10 < sup >− 3 </ sup > atm and found that, instead of an arc, the glow filled the tube.

These tubes didn't need gas in them to work, so they were evacuated to a lower pressure, around 10 < sup >− 9 </ sup > atm ( 10 < sup >− 4 </ sup > P ).

High inside pressure inhibits motion because the temperature differences are not enough to push the vanes through the higher concentration of air: there is too much air resistance for " eddy currents " to occur, and any slight air movement caused by the temperature difference is damped by the higher pressure before the currents can " wrap around " to the other side.

Traditionally, liquid helium is used to cool the coils because it has a boiling point of around 4 K at ambient pressure, and cheap metallic superconductors can be used for the coil wiring.

Diffusion pumps cannot discharge directly into the atmosphere, so a mechanical forepump is typically used to maintain an outlet pressure around 0. 1 mbar.

This roughly translates into needing around ten thousand times atmospheric pressure to reduce the volume of a substance by one percent.

The additional complexity for the Diesel formula comes around since the heat addition is at constant pressure and the heat rejection is at constant volume.

After mixing with water vapor and expired CO < sub > 2 </ sub > in the lungs, oxygen diffuses down a pressure gradient to enter arterial blood where its partial pressure is around 100 mmHg ( 13. 3 kPa ).

The " Classical Age " in India began with the Gupta Empire and the resurgence of the north during Harsha's conquests around the 7th century CE, and ended with the fall of the Vijayanagara Empire in the south in the 13th century, due to pressure from the invaders to the north.

Under the rules of Hammurabi's successors, the Babylonian Empire was weakened by military pressure from the Hittites, who sacked Babylon around 1531 BC ( short ).

The coronal discharges identified as Kirlian auras are the result of stochastic electric ionization processes, and are greatly affected by many factors, including the voltage and frequency of the stimulus, the pressure with which a person or object touches the imaging surface, the local humidity around the object being imaged, how well grounded the person or object is, and other local factors affecting the conductivity of the person or object being imaged.

The Zaghawa were supposedly forced southwest towards the fertile lands around Lake Chad by political pressure and desiccation in their former range.

SSV run at partial atmospheres ( typically around 1 / 3 of full atmospheric pressure ) in a hybrid of vacuum and conventional kiln technology ( SSV kilns are significantly more popular in Europe where the locally harvested wood is easier to dry versus species found in North America ).

During the 19th century, after Schleswig-Holstein had come under the government of Prussia ( from 1871 the German Empire ) following the Second Schleswig War in 1864, a combination of naval interests — the German navy wanted to link its bases in the Baltic and the North Sea without the need to sail around Denmark — and commercial pressure encouraged the development of a new canal.

A substantial simplification proposes that other forms of energy changes are inconsequential during the flow of air around a wing and that energy transfer in / out of the air is not significant, so the sum of pressure energy and speed energy for any particular parcel of air must be constant.

Very occasionally, if there is concomitant increased intracranial pressure, the sheath around the optic nerve may be cut to decrease the pressure.

Idiopathic intracranial hypertension ( IIH ), sometimes called by the older names benign intracranial hypertension ( BIH ) or pseudotumor cerebri ( PTC ), is a neurological disorder that is characterized by increased intracranial pressure ( pressure around the brain ) in the absence of a tumor or other diseases.
