Catalysts that speed the reaction are called positive catalysts.

The speed at which a reactions takes place is studied by reaction kinetics.

Catalysts are substances which change the pathway ( mechanism ) of a reaction which in turn increases the speed of a reaction by lowering the activation energy needed for the reaction to take place.

Catalysts can only speed up the reaction – chemicals that slow down the reaction are called inhibitors.

The reaction speed is increased, with an entire brigade on standby readiness ; the military retains the capability to continually deploy 2, 000 soldiers in international service or 5, 000 over a short time span.

* Decision / reaction time / speed ( Gt ) reflects the immediacy with which an individual can react to stimuli or a task ( typically measured in seconds or fractions of seconds ; it is not to be confused with Gs, which typically is measured in intervals of 2 – 3 minutes ).

:" Although theoretical calculations can be made today, the eventually attainable range of chemical reaction cycles, error rates, speed of operation, and thermodynamic efficiencies of such bottom-up manufacturing systems cannot be reliably predicted at this time.

range of chemical reaction cycles, error rates, speed of operation, and thermodynamic

When comparing the speed of a punch and the reaction time and time taken to block effectively, it is difficult to block a punch.

* Speed ( SPD ) represents reaction speed and, in some editions, movement rate.

This change in speed forces a designer to change from impulse at the base, to a high reaction style tip.

Even the inherent statistical fluctuations of neutron multiplication within the chain reaction, have implications with regard to implosion speed and symmetry.

However, the dynamic inertia ( from the gyroscopic reaction effect ) from the gimbal provides negative spring stiffness proportional to the square of the spin speed ( Howe and Savet, 1964 ; Lawrence, 1998 ).

Detonation is distinct from deflagration in that the chemical reaction propagates faster than the speed of sound ( often many times faster ) in an intense shock wave.

The pace of a bowler not only challenges the reaction speed of the batsman, but also his physical courage.

The speed of that reaction and the ignition of the resulting hydrogen can easily account for the explosion verified.

This scanning method usually has a low reaction latency and the scan speed can be varied.

Enzymes are protein catalysts for chemical reactions ; as catalysts, they speed up reactions without being used up in the process, so only small enzyme quantities are required to carry out a reaction.

However, external torques on the spacecraft may require a gradual buildup of reaction wheel rotation speed to maintain the spacecraft in a fixed orientation.

The strength of the materials of a reaction wheel determines the speed at which the wheel would come apart, and therefore how much angular momentum it can store.

Since the reaction wheel is a small fraction of the spacecraft's total mass, easily-measurable changes in its speed provide very precise changes in angle.

To speed up the construction works, the Polish government in November 1924 signed a contract with the French-Polish Consortium for Gdynia Seaport Construction, which by the end of 1925 had built a small seven-metre-deep harbour, the south pier, part of the north pier, a railway, and had also ordered the trans-shipment equipment.

Because of works connected with the Marmaray and Istanbul-Ankara high speed line there are currently no rail services linking Istanbul with the rest of Anatolia.

And this leads to the question of how atomic speed and motion works.

Zaharoff had knowledge, with astonishing speed, of the young inventor and Spanish Navy officer's works.

Due to the way his style works they believe in minimal movement with maximum effect and extreme speed.

This works out to a speed of 37. 5 mph for his entire performance.

Another advantage is that the rocket works even at zero forward speed, whereas a ramjet requires forward motion to feed air into the engine.

Several works of fiction explain pyrokinetic powers as being the ability to excite or speed up an object's atoms, increasing their thermal energy until they ignite, not necessarily objects, but also air particles.

An interesting comparison between privatization versus government-sponsored public works involves high speed rail ( HSR ) projects in East Asia.

The amount of texture that can be produced depends on the finish or tooth of the paper ( R or CP paper works best ), the size of the brush, the consistency and quantity of the paint in the brush, and the pressure and speed of the brush stroke.

The radial mechanism works best for CD-ROMs, though, as the speed of the disc increases.

* With his School of American Ballet, New York City Ballet, and 400 choreographed works, Balanchine transformed American dance and created modern ballet, developing a unique style with his dancers highlighted by brilliant speed and attack.

Blind Guardian's first two albums, Battalions of Fear and Follow the Blind, were more in the style of speed metal than their following works.

The technique works best on loose surfaces where the friction between the tires and the road is not too high, but can also be used on asphalt or other surfaces with high friction if the vehicle has enough power to maintain speed.

The entire Rio – São Paulo area is also sometimes considered a conurbation, and plans are in the works to connect the cities with a high speed rail.

Some of his other works from that period are DIECIMILA ( 1977 ), a facsimile of an Italian 10, 000 Lira note, possibly the first fine art print that ( like paper money ) is printed on both sides of the paper ; The Speed of Light Machine ( 1983 ), in which he reconstructed a scientific experiment with which to " see " the speed of light ; and the installation C. B. T. V.

He works at extraordinary speed ; a device can be invented, prototyped and tested within the course of a single episode.

Notable exhibits include the 1936 twin engined Alfa Romeo Bimotore which has a top speed of, Jim Clark's World Championship winning Lotus 25, the ' howling ' flat 12 Ferrari 312B, and Stirling Moss's Lotus, in which he defeated the Ferrari works team in the 1961 Monaco Grand Prix.

( note that some high water signs are posted to alert drivers of a flood prone area and do not actually mean that there is a flooded section of road ahead ) In France, Italy, Spain, Norway etc., warning ( and speed limit ) signs connected with road works have yellow background, these countries normally have white background on signs.

For example, the northbridge from the Nvidia nForce2 chipset will only work with Socket A processors combined with DDR SDRAM ; the Intel i875 chipset will only work with systems using Pentium 4 processors or Celeron processors that have a clock speed greater than 1. 3 GHz and utilize DDR SDRAM, and the Intel i915g chipset only works with the Intel Pentium 4 and the Celeron, but it can use DDR or DDR2 memory.

A simple arrangement which works well at low speed.

These classical methods run into problems: symbolic differentiation works at low speed, and faces the difficulty of converting a computer program into a single expression, while numerical differentiation can introduce round-off errors in the discretization process and cancellation.

That 17-second running time works out to an average camera speed of approximately 37. 5 fps, a significant difference from Murch's report.

The grinding works on the principle of critical speed.
