Equilibrium moisture content (EMC)/equilibrium relative humidity (ERH) studies pertaining to rice and rice products were reviewed. Methods of determining rice and rice component EMC/ERH data varied, using procedures involving static and dynamic equilibration methods, as well as direct gravimetric methods and indirect ERH‐measurement methods. Methods for measuring rice and rice component moistur...

_________________________________________________________________________ This paper reviews the role of micro non-convexities in the study of business cycles. One important nonconvexity arises because an individual can work only one workweek length in a given week. The implication of this non-convexity is that the aggregate intertemporal elasticity of labor supply is large and the principal ma...

The spectrophotometric procedure for determining the specific activity of the enzyme and the preparation of reagents employed in the assay have been described previously (3). DPiV-Commercial preparations of DPN (60 per cent) were used in routine assays. For critical experiments, commercial DPN was further purified by several adsorptions on Dowex 1 formate columns by the method of Kornberg and P...

The present work is concerned to remove Cu using the biosorption potential of fungal biomass Aspergillus oryzae. The dry fungal biomass was used to optimize various parameters such as contact time, initial metal ion concentration, pH, biomass loading etc. A maximum of 91% Copper removal was observed in 5 mg/L initial Copper metal ion concentration using dry Aspergillus oryzae biomass. The perce...

UDP-galactose 4-epimerase from Escherichia coli is a homodimer of 39 kDa subunit with non-covalently bound NAD acting as cofactor. The enzyme can be reversibly reactivated after denaturation and dissociation using 8 M urea at pH 7.0. There is a strong affinity between the cofactor and the refolded molecule as no extraneous NAD is required for its reactivation. Results from equilibrium denaturat...

Equilibrium studies in aqueous solution are reported for dibutyltin(IV) (DBT) complexes of the zwitterionic buffers "Good's buffers" Mes and Mops. Stoichiometric and formation constants of the complexes formed were determined at different temperatures and ionic strength 0.1 mol·L-1 NaNO3. The results show that the best fit of the titration curves were obtained when the complexes ML, MLH-1, MLH-...

UDP-galactose 4-epimerase from yeast (Kluyveromyces fragilis) is a homodimer of total molecular mass 150 kDa having possibly one mole of NAD/dimer acting as a cofactor. The molecule could be dissociated and denatured by 8 M urea at pH 7.0 and could be functionally reconstituted after dilution with buffer having extraneous NAD. The unfolded and refolded equilibrium intermediates of the enzyme be...

In this study, the MHD equilibrium limit of LHD plasmas is studied using a 3D MHD equilibrium calculation code, HINT2, which is an initial value solver based on the relaxation method without the assumption of nested flux surfaces. For finite beta equilibria, flux surfaces become stochastic in the peripheral region. However, though the axis shifts until the conventional limit, the separatrix to ...

The interaction between nocodazole and calf brain tubulin in 10(-2) M sodium phosphate, 10(-4) M GTP, and 12% (v/v) dimethyl sulfoxide at pH 7.0 was studied. The number of binding sites for nocodazole was shown to be one per tubulin monomer of 50,000 as a result of equilibrium binding studies by gel filtration and spectroscopic techniques. The presence of microtubule-associated proteins did not...

Gossypin is a glucosyl flavone obtained from the flowers of Hibiscus pitifolius (Malvaceace). It has potent analgesic and antiinflammatory activity. It has shown cytotoxic activity when tested against human lung adrenocarcinoma cell lines (A549). It has been shown to suppress angiogenesis, inflammation, and carcinogenesis. The mechanisms of these activities, however, are unknown. Because of the...
