Suction measurement has a vital role in unsaturated soil analysis. However, measuring suction remains challenging task due to number of issues such as the limited range measurement, cavitation, or long equilibrium time. It is even more when be carried on field. Hence, development new device which able measure high for duration without tedious maintenance and yet portable enough site required. I...

While tensile strength has been evaluated in the field of general surgery," to date it has not been evaluated for ophthalmic wounds. These methods for measurement of tensile strength allow objective determina­ tion and comparison of incision and suture techniques. The method to be described utilizes a tensiometer to determine the re­ gain of strength following keratome in­ cisions through the l...

Tensiometers are commonly used for measuring soil water matric pressures. Unfortunately, the water-filled reservoir of conventional tensiometers limits their applicability to soil water matric pressures above approximately20.085 MPa. Tensiometers filled with a polymer solution instead of water are able to measure a larger range of soil water matric pressures. We designed and constructed six pro...

Two measurement techniques to determine the surface tension of ferrofluids using the perpendicular field instability are described. Four ferrofluid layers were examined with magnetic field applied perpendicularly to the surface of s1d oil-based ferrofluid in air; s2d water-based ferrofluid in air, s3d oil-based ferrofluid, and s4d fluorocarbon-based ferrofluid, both below a blend of 50% n-Propy...
