reinforcement realism

within a textile/rubber composite, the textile portion is every bit as important as the compounding ingredients in the rubber recipe, as far as the product and its end use are concerned. just as with the compounding ingredients, the properties of the textiles to be used must be accurately known, and it is particularly important to know of..

effects of the ethylene oxide distribution on nonionic surfactant properties

draves wetting data show that narrow-range products wet cotton substrates more efficiently than normal-distribution materials narrow-range ethoxylates exhibit higher aqueous surface tension and higher polyester adhesion tension values than their broad-range counterparts. in addition, narrow-range surfactants reduce the interfacial tension..

mutagenic potential of ammonia-related aflatoxin reaction products in cottonseed meal

in a joint research effort, the food and drug administration, the national toxicology program and the us department of agriculture studied the mutagenic potential of aflatoxin reaction products following ammoniation of contaminated cottonseed meal under conditions approximating those approved for commercial ammoniation of nonaflatoxin-con..

identification of highly-ionized xenon spectra (xe xxvi through xxxi) excited in the plasma of the tfr tokamak

the spectrum of xenon injected into the tfr tokamak plasma has been recorded in the range 10-90 a by means of a 2 m grazing incidence spectrograph. forty-four lines and unresolved transition arrays pertaining to multicharged xenon ions isoelectronic with cu i, ni i, co i, fe i, mn i and cr i have been identified by means of various theore..

ins and outs of programmable controllers

the history of programmable controllers is briefly surveyed and current advances are reviewed. the p/c size reduction, interworking, intelligent input/output modules, diagnostic modules, and artificial intelligence programs are discussed

distribution of residual pesticide withint textile structures as determined by electron microscopy

an electron microscopical technique was developed to determine the location and distribution of the organophosphorus pesticide, malathion, on and within yarns and fibers. x-ray microanalysis and backscattered electron imaging of contaminated fiber cross sections was accomplished by using oso//4 as a tag for the pesticide. on contaminated ..

deplacements isotopiques relatifs et moments quadrupolaires intrinseques des isotopes du plutonium. $left bracket$ relative isotopic shifts and intrinsic quadrupole moments of plutonium $right bracket$

extensive isotope shifts mearsurements in the 3910-9160 a region of the plutonium spectrum were made. this enables us to determine with precision the value of the relative isotope shift (r i. s. ) between the 244-242 and 242-240 couples of isotopes. the value found for the r. i. s. is 1. 03 $plus or minus$ 0. 02 based on the optical r. i...

parametric studies of 3d**n ground configurations in highly charged ions

parameters needed for an accurate interpretation of the 3d**n ground configurations within the framework of the slater-condon theory, are determined by generalized least square techniques from energy levels of various ions simultaneously. two kinds of assumptions on the smooth evolution of the parameters, along a period of ions of the sam..

assessment of co//2 corrosion in the cotton valley limestone trend

co//2 corrosion in gas, gas-condensate, and oil wells has remained elusive to prediction of its kinetics, rate, and morphology prior to failure. however, it can be shown that within the context of the corrosion mechanism, a qualitative assessment of corrosivity can be obtained. furthermore, a quantitative assessment of inhibition can be o..

interpretation parametrique des configurations impaires de l'europium (eui). $left bracket$ parametric interpretation of the odd configurations of europium (eui) $right bracket$

ninety-seven odd levels of eui belonging to the sub-configurations 4f**7(**8s)6s**2, 4f**7(**8s)5d6s, 4f**7(**8s) 6s6d, 4f**7(**8s)5d**2 et 4f**7(**8s)6p**2 have been interpreted by means of the slater-condon parametric theory by taking into account configuration mixing and the effect of upper terms arising from 4f**7 **6p. the r. m. s. d..
