The kinetics and mechanism of adsorption of two commercial dyes (BR22, AB25), phenol, and 3-chlorophenol from water on activated carbons were studied at 30 degrees C. The activated carbons were prepared from plum kernels, and the activation temperature and time tested were in the ranges 750-900 degrees C and 1-4 h, respectively. Three simplified kinetic(More)
We report the first observation of dijet events with a double Pomeron exchange topology produced in &pmacr;p collisions at sqrt[s] = 1800 GeV. The events are characterized by a leading antiproton, two jets in the central pseudorapidity region, and a large rapidity gap on the outgoing proton side. We present results on jet kinematics and production rates,(More)
The unsteady-state electrical potential and the concentrations of ions between two identical, negatively-charged particles immersed in an a:b electrolyte solution are investigated. In particular, the effects of ionic strength, I, the geometric mean of the diffusivities of counterions Dcon and coions Dco, D, the separation distance between two particles, H,(More)

This Letter describes a direct measurement of the W boson total decay width, gamma(W), using the Collider Detector at Fermilab. The measurement uses an integrated luminosity of 90 pb(-1), collected during the 1994-1995 run of the Fermilab Tevatron p&pmacr; collider. The width is determined by normalizing predicted signal and background distributions to 49(More)
Weak current-induced baryonic form factors at zero recoil are evaluated in the rest frame of the heavy parent baryon using the nonrelativistic quark model. Contrary to previous similar work in the literature, our quark model results do satisfy the constraints imposed by heavy quark symmetry for heavy-heavy baryon transitions at the symmetric point v · v′ =(More)
