Cannonball TargetContinued from page 9tion—above 50 percent—and a highhydrodynamic efficiency in the rangeof 16 percent. The numbers of hotelectrons emitted from the rear of thefirst type of cannonball target werefound to be less than those seen in thesingle-foil ablative target. This tendencywas even more noticeable for thesecond type.Overall, the energetic hot electronsare mainly absorbed by the cannonballSecond LawContinued from page 63lows us to measure certain global featuresof the electromagnetic action ofwhich the motion is a by-product; butall causal action must be fundamentallyhydrodynamic in character ratherthan randomly statistical.The true refutation of the SecondLaw begins with the existence of theauthor. Since life exists, and it can notexist upon the premises of entropytheory, then it is that theory—ratherthan life—that is wrong.—Carol WhiteMeasure Up toTake the guesswork out of aestheticform and function, and with precisionand ease allow the time proven goldenproportion to work for you. TheseGolden Link Calipers will enable youto proportionally measure many things,both great and small, from the ringsand moons of Saturn, to random cracksin trees, to a phylum of solitary bees.With the Golden Link Calipers, youcan see how the golden proportionpredominates in great art, in the laboratory,and in nature. Invented by adentist and engineer to aid in makingwell-proportioned prosthetics, theGolden Link Calipers have many usesfor geometers, artists, architects, designers—andcreative minds in general.To order:Send check or money order for $103.45($98.95 plus $4.50 shipping) toNestor Engineering Associates, Inc.Division of Surgical Instruments148 NE 28th Street Miami, FL 33137cavity wall. Their energy is thus convertedinto plasma generation andheating, which then effectively drivesthe implosive acceleration of the innersurface representing the fuel targetsurface in this experiment. Furthermore,low-energy hot electrons in thecavity also become useful in drivingthe implosion of the inner surface.It was found that the formation ofthe cavity structure of a plane foil canmodify the energy distribution of thehot electrons. This modification of thehot-electron spectrum appears to dependon the cavity materials and geometry.Therefore, proper design ofspherical cannonballs can suppress thehot-electron preheating of pellet fusionfuel otherwise seen in direct-drive,long-wavelength laser fusion.Osaka is also continuing work oncannonball targets with other types ofinertial confinement fusion drives suchas short wavelength lasers and particlebeams. By exploring various cannonballconfigurations with a wide rangeof different drivers, they plan to demonstratethe science needed for highgain inertial fusion energy generation.—Charles B. StevensAids Spreads Like TBContinued from page 8disease" as a direct result of the introductionof just one infected animal.It seems probable that in the prosperousWest, LAV is still only transmittedby per-cutaneous inoculation, orby anal intercourse, but that in thetropics it is already being spread alsoby the respiratory route with or withoutthe cooperation of M tuberculosishominis. The prospects for the lessprosperous inhabitants of the crowdedcities and villages of the world beyondthe next decade are bleak. 15References1. J.M. Ziza, F. Brun-Vezinet, A.

Thatwould be very unlikely to occur with the referee system ofjudging papers for acceptance that is now in use in mostscientific journals. The referees always base their reviews onwhat is known in physics, biology, or biophysics as it standstoday; but often there is a greater understanding, newinterpretations, new explanations for scientific phenomenathat should becoyne known and discussed. It is the IJFEeditorial policy to give authors with a new concept a chanceto defend their ideas and theses before acceptance forpublication."
