Let Q be a nonsingular quadric surface bearing reguli Af and Af, and let **zg be a Af curve of order K on Q.

The class of the congruence is Af, since an arbitrary plane meets **zg in K points.

Since the complex of singular lines is of order K and since there is no complex of invariant lines, it follows from the formula Af that the order of the involution is Af.

Since C is rational, this correspondence has K coincidences, each of which implies a line of the pencil which meets its image.

For if such were the case, either the plane of the two lines would meet **zg in more than K points or, alternatively, the order of the image regulus of the pencil determined by the two lines would be too high.

The K factor, a term used to denote the rate of heat transmission through a material ( B.t.u./sq. ft. of material/hr./*0F./in. of thickness ) ranges from 0.24 to 0.28 for flexible urethane foams and from 0.12 to 0.16 for rigid urethane foams, depending upon the formulation, density, cell size, and nature of blowing agents used.

Table 1,, p. 394, shows a comparison of K factor ratings of a number of commercial insulating materials in common use, including two different types of rigid urethane foam.

The man most firmly at grips with the problem is the University of Minnesota's Physiologist Ancel Keys, 57, inventor of the wartime K ( for Keys ) ration and author of last year's bestselling Eat Well And Stay Well.

The equilibrium constant K is an expression of the equilibrium concentrations of the molecules or the ions in solution.

The acid dissociation constant K < sub > a </ sub > is generally used in the context of acid-base reactions.

The stronger of two acids will have a higher K < sub > a </ sub > than the weaker acid ; the ratio of hydrogen ions to acid will be higher for the stronger acid as the stronger acid has a greater tendency to lose its proton.

Charles K. Smith argues that Swift ’ s rhetorical style persuades the reader to detest the speaker and pity the Irish.

To do this, Moseley measured the wavelengths of the innermost photon transitions ( K and L lines ) produced by the elements from aluminum ( Z = 13 ) to gold ( Z = 79 ) used as a series of movable anodic targets inside an x-ray tube.

Maj. Gen. Polk ignored the problems of Fort Henry and Fort Donelson when he took command and, after Johnston took command, at first refused to comply with Johnston's order to send an engineer, Lt. Joseph K. Dixon, to inspect the forts.

The Institute was founded in 1986 by K. Eric Drexler, no longer with the Institute, along with his then wife Christine Peterson, who is now President.

K. Eric Drexler considers an accidental " grey goo " scenario extremely unlikely and says so in later editions of Engines of Creation.

In light of this perception of potential danger, the Foresight Institute ( founded by K. Eric Drexler to prepare for the arrival of future technologies ) has drafted a set of guidelines for the ethical development of nanotechnology.

He was an outspoken critic of the idea of molecular assemblers, as advocated by K. Eric Drexler and introduced scientific objections to them.

Among them were Walter Cronkite, David Brinkley, Edwin Newman, Harrison Salisbury, several of the core members of Edward R. Murrow's famed Murrow's Boys: Charles Collingwood, Eric Sevareid, Richard C. Hottelet, Howard K. Smith, and Larry LeSueur.

It was probably the priest who received Jones into the Church, Father John O ' Connor ( in fact the model for G. K. Chesterton's Father Brown character ), who suggested that he contact the Catholic artist Eric Gill.

The Crickets released " The Crickets and Their Buddies " in 2004 which features several classics from all parts of their career featuring guest appearances by several prominent artists including Eric Clapton, Rodney Crowell, Waylon Jennings, Nanci Griffith, John Prine, Graham Nash, Bobby Vee, Tonio K. and more.

On October 12, 1999, General Eric K. Shinseki, Chief of Staff of the Army, announced I Corps would lead the acceleration of Army transformation, training and the initial creation of the first two Stryker Brigade Combat Teams at Fort Lewis.

On September 19, 2001, Sergeant Major of the Army Jack L. Tilley presented Mauldin with a personal letter from Army Chief of Staff General Eric K. Shinseki, a hardbound book with notes from other senior Army leaders and several celebrities to include Walter Cronkite, Tom Brokaw and Tom Hanks.

This may lead to a molecular assembler, according to some, such as K. Eric Drexler, Ralph Merkle, and Robert Freitas, and of the potential for integrating vast numbers of assemblers into a kg-scale nanofactory.

Exploratory engineering is a term coined by K. Eric Drexler to describe the process of designing and analyzing detailed hypothetical models of systems that are not feasible with current technologies or methods, but do seem to be clearly within the bounds of what science considers to be possible within the narrowly defined scope of operation of the hypothetical system model.

While both critics and proponents often agree that much of the highly detailed simulation effort in the field may never result in a physical device, the dichotomy between the two groups is exemplified by the situation in which proponents of molecular nanotechnology contend that many complicated molecular machinery designs will be realizable after an unspecified " assembler breakthrough " envisioned by K. Eric Drexler, while critics contend that this attitude embodies wishful thinking equivalent to that in the famous Sidney Harris cartoon ( ISBN 0-913232-39-4 ) " And then a miracle occurs " published in the American Scientist magazine.

During Wolfowitz's pre-war testimony before Congress, he dismissed General Eric K. Shinseki's estimates of the size of the post war occupation force and estimated that fewer than 100, 000 troops would be necessary in the war.

However, he did visit the festival as director of a production of the Eric Bogosian play Talk Radio with a cast which included Phil Nichol, Mike McShane, Will Adamsdale, Stephen K Amos and Tony Law.

Other well-known advocates of the anticipatory approach include Newt Gingrich, Heidi Toffler, K. Eric Drexler, and Robin Hanson.

A molecular assembler, as defined by K. Eric Drexler, is a " proposed device able to guide chemical reactions by positioning reactive molecules with atomic precision ".

A typical nanofactory would fit in a desktop box, in the vision of K. Eric Drexler published in Nanosystems: Molecular Machinery, Manufacturing and Computation ( 1992 ), a notable work of " exploratory engineering ".

It has been suggested, notably by K. Eric Drexler, that mechanosynthesis will be fundamental to molecular manufacturing based on nanofactories capable of building macroscopic objects with atomic precision.
