    Notes: Abstract The activity changes of isozymes of nuclear protein tyrosine kinase (nPTK) during chemically induced hepatocarcinogenesis in rats was studied. Two isozymes were isolated from rat liver by using ion exchange chromatography. These two isozymes were designated as nPTK-I and nPTK-II, and were found to be minor and major components of total nPTK respectively. These proved to be two different enzymes due to their different characteristics, such as molecular weights, electrical charges and kinetics. The specific activity nPTK-I and its percentages in total nPTK significantly increased in preneoplastic stage (week 10) and slightly elevated further in neoplastic stage (week 18). The specific activity of the nPTK-II moderately increased at week 10, but compared to its value at week 10, it decrease at week 18, resulted in gradual decrease of its percentage in total nPTK. These results indicate that rat hepatic nPTK-I and nTPK-II may be related to neoplastic and preneoplastic stages of rat liver respectively.

    A free radical copolymerization model for simulating reactive processing of unsaturated polyester resins (1990)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: A free radical copolymerization model is proposed for simulating the reaction rates and conversions of styrene monomer and unsaturated polyester resins during curing. This model is based on film theory in which the rate constants reflect both reaction and diffusion resistances. Differential scanning calorimetry in combination with Fourier transform infrared spectroscopy is used to measure the overall and individual reactivities of reacting species. Model parameters are determined from experimental data. The applicability of this model is demonstrated in a cure simulation.

    Phosphorylation of yeast protein: Reduction of ribonucleic acid and isolation of yeast protein concentrate (1986)

    Notes: Yeast nucleoproteins were chemically phosphorylated with phosphorus oxychloride (POCL3). Studies using 31P nuclear magnetic resonance (NMR) spectroscopy, stability to pH and lysine estimation all indicated that the ∊-amino group of lysine was the principal functional group phosphorylated. Phosphorylation of ca. 30% of the lysine residues resulted in removal of more than 85% of contaminant ribonucleic acid from protein precipitated at pH 4.2. Phosphorylation did not alter the amino acid composition of yeast proteins and was reversible under acidic conditions. Based on the data, a method for the preparation of phosphorylated yeast protein with low levels of nucleic acid is proposed.

    Notes: A recent design procedure for perforated plate extraction columns requires extension to include jetting conditions at each perforation. For this purpose, correlations are obtained for jet length, jet contraction, drop size, and mass transfer coefficients in disperse phase controlled liquid-liquid systems. Experimental variables include nozzle size, flow velocity, and physical properties.

    Notes: This study enables the extension of a recent design procedure for perforated plate extraction columns to include operation under jetting conditions. Correlations of experimental data are given for jet length, jet contraction, drop size, and mass transfer rates in continuous phase controlled liquid-liquid systems. Systems exhibiting very low mass transfer rates were used, and this gave significantly different results from those obtained earlier with moderate rates of mass transfer.

    Notes: A kinetic model has been developed for radical chain growth type of reactive polymer processing operations. This model incorporates considerations of the molecular diffusion that is described by a free volume theory and the basic reaction mechanism of the free-radical chain polymerization. Experimental results from the bulk styrene polymerization and a reaction of sheet molding compound (SMC) showed good agreement with the model.
