A Simple Theoretical Model for Prediction of Phase Inversion
Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were c...
متن کاملThe nucleon spin structure in a simple quark model
We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional 3q structure, different (3q)(QQ̄) admixtures in the nucleon wavefunction are also taken into account. The contributions to the nucleon spin from various components of the nucleon wavefunction are discussed. The effect due to the Melosh-Wigner rotation is also studied. PACS nu...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Quark Fragmentation : Some Simple Tests for Qcd
The effect of quark and gluon spin on the fragmentation of energetic quarks into hadrons is discussed. Particle ratios and polarization for wide-angle mesons and baryons are given. In particular, we find p/r = 1 with the p’s longitudinally polarized. It is found that circularly polarized photon beams can serve as a source of polarized quarks and that h's produced in the photon fragmentation reg...
متن کاملA Simple Model for the Quark Fragmentation Functions Seen in Deep Inelastic Processes*
Using some simple .ass.mptions, we present in this paper a calculation of the quark fragmentation functions seen in deep inelastic processes. The results provide evidence for the conjecture that both jets seen in high p1 reactions at the ISR stem from similar parents. The calculated functions are in excellent agreement with the inclusive distributions seen in vp and tp scattering,and in particu...
