Dilute oil-in-water emulsions stabilised with anionic soaps were coagulated by the addition of salt. After a predetermined time coagulation was stopped by diluting with a solution of a nonionic surface active agent. The rate of coagulation was measur

Mixtures of high-melting glycerides can be separated into their constituents by means of a chromatographic process resembling repeated fractional crystallization. Use is made of a column in which a temperature gradient is established, and of solvent

A new optical bulk current sensor is presented with Bi(12)SiO(20) as a sensing crystal. Through the use of a mirror in the setup and the reciprocity of the optical activity of Bi(12)SiO(20), the sensor becomes insensitive to intrinsic linear birefrin

We have compared muscle activation in the control of slow isotonic movements and isometric contractions. Specific attention has been given to the contribution of the two force-grading mechanisms, the recruitment of motor units and the modulation of f

This paper reports creep measurements on paraffin oil in aqueous solution emulsions, stabilized by partially esterified polymethacrylic acid. The measurements are taken at low pH, where this polyelectrolyte is known to exhibit strong inter- and intra

For measurements of viscoelastic properties of monolayers spread on liquids the use of longitudinal surface waves is discussed. The conventional theory is somewhat modified; use is made of the telegraph equations analogous to descriptions of other wa

Paraffin oil-in-water emulsions stabilized by partially esterified polymethacrylic acid (PMA-pe) develop substantial elasticity at low pH because of the formation of polyelectrolyte-polyelectrolyte bridges between the emulsion droplets. The contact r

A new method is described for the measurement of dilational surface properties of solutions containing surface-active materials. The surface dilational modulus is obtained from a surface-tension variation, caused by a small-amplitude, sinosoidal-area
