Density, ultrasonic velocity and viscosity of caffeine a pharmaceutically significant drug in water at four temperatures were measured. The partial molar volume ($Vo), partial molar compressibility (d,o) and the viscosity B coefficient were calculated from the experimental data. Values of QIVO and $

The viscosity B-coefficient, B,, of the total salt was found to be linearly related with the molal volume, v&, of the hydrated salt according to the equation, B, = aV$, -b. The coefficients a and b were calculated to be 2.8, and 0.19, at 25°C and 2.6, and 0.20, at 5"C, respectively. The V& values at
Studies were performed to examine the effect of ionic salts on phase transitions, dissolution rates, and diffusion coef®cients of water in gels of poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) with polymer concentrations ranging from 22 to 32% w/w and salt concentrations rangin
On p. 543, in Fig. , the filled squares represent the relative partial molar enthalpy and not the relative apparent molar enthalpy. As a consequence, Eq. [1] and the resulting broken line that appears in Fig. as well as the value of DH M in Table should be removed. Finally, the quantity F L that a
