    Identification of cyclic metabolites of isopropylated phenyl phosphates in rabbit bile (1990)

    Notes: Some organophosphorous compounds, especially tri-o-cresylphosphate (TOCP), induce delay neuropathy. The cyclic saligenin phosphate (PSP) has been suggested to be the active metabolite of the protoxicant TOCP. The o-isopropylated triphenyl phosphates have been proven not to be neurotoxic. Studying the metabolism of these compounds we found the following cyclic metabolites: 2-phenyl-4H-4,4-dimethyl-1,1,3,2-benzodioxaphosphoran-2-oxide and 2-(o-isopropylphenyl)-4H-4,4-dimethyl-1,1,3,2-benzodioxaphosphoan-2-oxide. Additionally, monohydroxylated metabolites of the parent esters were detectable. The effect of glucuronidation on the formation of the cyclic metabolites is discussed in this paper.

    Notes: Using VO2+ as a spin probe, a new method to obtain microenvironmental information on supports was developed which can be used in the choice of supports for coordination catalysts. Utilizing the above method, NaY was chosen as second support component. A complex support catalyst VOCl3/MgCl2/NaY/Al2Et3Cl3 was prepared and used in ethylene-propylene copolymerization. Higher polymerization activity was obtained with this catalytic system. Alternating the ratio of two kinds of supports, the composition and sequence structure of copolymers could be controlled, which showed that NaY participated in the active species, affected the insertion of monomer, and changed the composition and sequence structure of copolymers. © 1994 John Wiley & Sons, Inc.

    Preparation of gradient-index (GRIN) polymer fibers for imaging applications (1996)

    Notes: A closed extrusion process combined with a core-shell separation die design is developed in this study for preparing gradient index (GRIN) polymer fibers with a quadratic distribution of the refractive index. The material system used in this investigation is methyl methacrylate (MMA, n = 1.49) and benzyl methacrylate (BzMA, n = 1.568). The refractive index differences between the center and the periphery (Δn) of the prepared polymer fibers increase from 0.0115 to 0.020 when BzMA in the reactant mixtures increases from 17 to 28%. This finding would suggest that increasing the high refractive index monomer in the reactant mixture increased Δn. The Δn values decrease from 0.018 to 0.0135 when the diffusion zone temperature increases from 70 to 90°C. The diffusion rates of the monomers increase with the temperature, thereby causing BzMA and MMA to distribute more uniformly at a higher temperature than at a lower one. This uniform distribution leads to the decrease of Δn with an increasing temperature. The prepared GRIN polymer fibers have potential applications as imaging lenses for scanners, fax machines, and copiers. © 1996 John Wiley & Sons, Inc.

    Solvent effect on the action of ethylene-vinyl acetate copolymer pour point depressant in waxy solutions (1996)

    Notes: The flowability and thermal behavior of waxy solutions with and without an ethylene-vinyl acetate copolymer (EVA) have been studied. The drastic changings of pour point depression (ΔTpp) and the crystallization in four waxy solutions were observed. These changes were linear with the U-interaction parameters between EVA and wax in different solvents, suggesting that the efficiency of EVA pour point depressent depends on its compatibility with wax, which is affected by solvent. © 1996 John Wiley & Sons, Inc.

    Estimation of true growth and product yields in aerobic cultures (1983)

    Notes: In the microbial production of useful products, it is important to understand the allocation of substrate energy for maintanance, growth, and product formation. Methods are presented to obtain point and 95% confidence interval estimates for the true growth yield parameter, true product yield parameter, and the maintenance parameter. Methods are presented which allow all data to be used simultaneously for those cases where more than the minimum number of measurements are made at each specific growth rate (or dilution rate). Three estimation methods and two forms of the energy allocation equations are investigated. Point estimates are similar for the three methods, but interval estimates are considerably larger for one of the three methods. The results depend on the form of the equations.

    Maximum likelihood estimation of growth yields (1982)

    Notes: This work is concerned with statistical methods to estimate yield and maintenance parameters associated with microbial growth. For a given dilution rate, an experimenter typically measures substrate concentration, oxygen utilization rate, the rate of carbon dioxide evolution, and biomass concentration. These correlated response variables each contain information about the maintenance and yield parameters of interest. A maximum likelihood estimator which combines this correlated information for the yield and maintenance parameters is proposed, evaluated, and tested on literature data. Both point and interval estimators are considered.

    Notes: Methods are presented for examining the consistency of experimental data for microbial growth where light energy is converted to chemical energy through photosynthesis. True growth yield and maintenance parameters are estimated for several sets of available experimental data. Methods of parameter estimation are presented which allow all of the measured variables to be used simultaneously for parameter estimation. The results show that a wide range of values have been found for the true growth yield and maintenance parameters. Values of the true growth yield range from 0.04 to values above those predicted by the Z-scheme model for photosynthesis.
