The present study was focusing on the effect of seminal fluid infection on sperm functions and fertilizing capacity of mouse spermatozoa. Two kinds of bacteria were isolated from seminal fluid of 14 infertile patients (23-51 years) during their attendance at the Institute of Embryo Research and Infertility Treatment involves Staphylococcus aureus (Staph. aureus) and Escherichia coli (E. coli), which were identified by biochemical tests and API systems.

    Vapor-Liquid-Liquid Equilibrium (VLLE) systems are complicated systems; they involve both a two phase liquid and a two phase vapor.Obtaining equilibrium data on these systems is very difficult, Vapor-LiquidEquilibrium (VLE) recirculation stills can not be used to obtain accurate VLLE data due to incorrect composition of the recycled condensed vapor to the boiler, modifications are made to these stills to obtain accurate equilibrium data for partial and immiscible liquid systems.Another difficulty when collecting the vapor & liquid samples, a modification

Various paths and models have been tested for more accurate VLE predictions for 36 binary systems with 376 data points and 14 ternary mixtures with 368 data points,especially for mixtures of industrial interest in refrigeration units.
