purpose: to evaluate the effect of vacuum and flow rate on endothelial cell loss after high versus low vacuum phacoemulsification. methods: this randomized clinical trial was performed on 60 eyes of 60 patients with moderate lens opacity (nuclear sclerosis 3+). all surgeries were performed by one experienced surgeon using stop and chop technique with sovereign white star machine (amo). patients...

Densities and viscosities of L-Threonine in water mixed aqueous solution tetrahydrofurfurylalcohol at 298.15K. On the basis these data ,the apparent molal volumes ,partial infinite dilution °, slop ,transfer volume , Gibbs free energy activation for viscous flow ΔG*1,2 B-coefficient have been calculated using Jones-Dole equation . The obtained thermodynamic properties discussed terms intermolec...

Building on the principles of structure-oriented lumping (SOL), chemistry-oriented lumping methods have been developed to describe the composition in tandem with the hydro-processing chemistry of heavy oils such as vacuum residue, de-asphalted oil, tar and bitumen. Recent advances in analytical chemistry have provided the necessary fundamental insights that are required to develop such models. ...

A study of collective behavior in heavy ion collisions provides one of the most sensitive and promising probes for investigation of possible formation of new extreme state of strong interacting matter and elucidating its properties. Systematic of experimental results for final state azimuthal anisotropy is presented for heavy ion interactions at RHIC. Experimental data for azimuthal anisotropy ...

Purpose This paper aims to present a detailed mechanical design of seven-degrees-of-freedom mobile parallel robot for the tungsten inert gas (TIG) welding and machining processes in fusion reactor. Detailed is presented both kinematic dynamic behaviors are studied. Design/methodology/approach First, model was created computer-aided (CAD) software, then simulation optimization were completed mee...
