• Novel, platinum-modified nickel-aluminide coatings that deliver unprecedented oxidation and phase stability as bond coat layers in thermal barrier coatings, which could improve the durability of gas turbine engines, allowing them to operate at higher temperatures and extending their lifetimes.

In February 2006, NRC Handelsblad started a morning newspaper, nrc • next, to attract educated readers who do not read a newspaper every day.

where ∇• S is the divergence of the Poynting vector ( energy flow ) and J • E is the rate at which the fields do work on a charged object ( J is the free current density corresponding to the motion of charge, E is the electric field, and • is the dot product ).

If S is a semigroup or monoid, then a set X on which S acts as above ( on the left, say ) is also known as a ( left ) S-act, S-set, S-action, S-operand, or left act over S. Some authors do not distinguish between semigroup and monoid actions, by regarding the identity axiom ( e • x = x ) as empty when there is no identity element, or by using the term unitary S-act for an S-act with an identity.

Sunnis that follow one of the four Sunni Schools of Law ( Hanafi • Shafi ` i • Maliki • Hanbali ) for the most part consider Khums to be something that exists, and do not consider it as an innovation.

• Believing that individual human joys and sorrows do not matter to a higher power.

• The Competent Authority in one Member State does not have jurisdiction in any other Member State, but they do exchange information and try to reach common positions.

• Accessing documents that are not confidential and do not deal with issues concerning the observers ;

• Its aim was to “ go to the people of London, especially the poor, to bring them to an acquaintance with Jesus Christ as Saviour, and to do them good by every means in their power .”

• Research is also being done on why certain treatments seem to help hemiballistic patients when they should seemingly do more harm.

• Sometimes part of the fuel leaks to the exhaust with the exhaust gases.

As an option can be thought of as ‘ price insurance ’ ( e. g., an airline insuring against unexpected soaring fuel costs caused by a hurricane ), TV can be thought of as the risk premium the option seller charges the buyer — the higher the expected risk ( volatility • time ), the higher the premium.

• Developed a method of separating plutonium and fission products from spent uranium fuel.

• Development of heterogeneous catalysts whose ability to be recycled could help reduce costs for production of biodiesel fuel and eliminate waste-storage costs.

; Closure: For all a, b in A, the result of the operation a • b is also in A.

; Associativity: For all a, b and c in A, the equation ( a • b ) • c = a • ( b • c ) holds.

The general chemical formula of an unmodified monosaccharide is ( C • H < sub > 2 </ sub > O )< sub > n </ sub >, literally a " carbon hydrate.

An inline 6-cylinder, diesel engine producing 3150 Nm ( 2323. 32 lb • ft ) of torque and fully complying with Euro 5 emission standards.

In the following, we use Earley's dot notation: given a production X → αβ, the notation X → α • β represents a condition in which α has already been parsed and β is expected.

Friends ( stylized as F • R • I • E • N • D • S ) is an American sitcom created by David Crane and Marta Kauffman, which aired on the National Broadcasting Company ( NBC ) from September 22, 1994 to May 6, 2004.

With s = T • s ( nT ), this Fourier series can now be recognized as a form of the Poisson summation formula.

The average density of granite is between 2. 65 and 2. 75 g / cm < sup > 3 </ sup >, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3-6 • 10 < sup > 19 </ sup > Pa · s.

• For one complete revolution of the crankshaft, the engine executes one cycle — the 4-stroke executes one cycle per two crankshafts revolutions.

• Less weight and easier to manufacture.

• The lack of lubrication system that protects the engine parts from wear.

Accordingly, the 2-stroke engines have a shorter life.

The chase scene featured Lola T70 Mk. IIIs with dummy turbine engines racing against Yamaha TA125 / 250cc 2-stroke race replica motorcycles through two San Francisco Bay Area automotive tunnels: the Caldecott Tunnel between Oakland and Orinda, and the underwater Posey Tube between Oakland and Alameda.

Amusement park go-karts can be powered by 4-stroke engines or electric motors, while racing karts use small 2-stroke or 4-stroke engines.

* 2-stroke kart engines are developed and built by dedicated manufacturers.

powered by 2-stroke engines designed by engineer Fryderyk Bluemke.

On large 2-stroke engines less than one revolution of the crankshaft is needed for starting.

The same applies to double acting diesel engines ( see also: H class battleship ( 1939 ): 12 MAN double-acting 2-stroke 9-cylinder diesels ).

Where early designs had two-stroke engines, there has been a move toward newer style 2-stroke and 4-stroke gas engines, some with over.

However, Detroit Diesel 2-stroke cycle engines commonly use oil cooled by water, with the water in turn cooled by air.

Amusement park go-karts can be powered by 4-stroke engines or electric motors, while racing karts use small 2-stroke or 4-stroke engines.

Outdoor tracks can offer low speed karts strictly for amusement ( dedicated chassis equipped with low powered 4-stroke engines or electric motors ), to faster, more powerful karts similar to a racing kart ( powered by 4-stroke engines up to 15 hp and more rarely by 2-stroke engines ) but designed to be more robust for rental use.

The engines themselves are of considerable interest as precursors, not of the first commercial gas engines ( e. g. Lenoir engine in 1860, which used the 2-stroke cycle without compression, or the Otto and Langen atmospheric engines ), but rather of the later generation of engines including Otto's engines operating on the 4-stroke cycle and Dugald Clerk's engine operating on the 2-stroke cycle, both with compression of the gas / air mixture in the cylinder.
