The mechanical properties of materials such as natural rubber composites determine their usefulness engineering or biological materials. thermodynamic filled with clay and corn cob at varying volume fraction filler were studied a view relating comparing parameters (ΔG, ΔH ΔS) to (Young’s modulus, tensile strength, elongation break, etc) composites. prepared using standard compounding recipe. te...

1. The local anaesthetic benzyl alcohol progressively activated glucagon-stimulated adenylate cyclase activity up to a maximum at 50 mM-benzyl alcohol. Further increases in benzyl alcohol concentration inhibited the activity. The fluoride-stimulated adenylate cyclase activity was similarly affected except for an inhibition of activity occurring at low benzyl alcohol concentrations (approx. 10 m...

The transition of the physical phase of lipids in membrane fragments of a blue-green alga Anacystis nidulans was studied by a spin labeling technique. The maximum hyperfine splitting of the electron spin resonance spectrum of the N-oxyl-4', 4'-dimethyloxazolidine derivative of 5-ketostearic acid plotted against the reciprocal of the absolute temperature gave a discontinuity point that was chara...

Thermal decomposition kinetics of calcium carbonate was studied by non-isothermal thermogravimetric analysis at different heating rates. The reaction mechanism was found to follow a two-dimensional phase boundary-controlled model by modelfree and model-fitting methods. Two non-Arrhenius equations (Harcourt–Esson equation and Berthelot–Hood equation) were used to interpret the decomposition kine...

Samples of 6 mol%Sc2O3 ? 1 mol% CeO2 co doped ZrO2 were fabricated by conventional ceramic processing methods and sintered at various temperatures from 1000?C to 1650?C in air. The sintering conditions on microstructure phase content are investigated using characterization methods, including pycnometry, diffraction, spectroscopy. electrical conductivity samples was electrochemical impedance spe...
