The Granular Matrix Sensor (GMS) is an indirect method for soil suction measurement. Since GMS comparatively inexpensive, robust and usually provide continuous data, it a natural candidate civil engineering practice. sensor has been used mainly irrigation purposes, also some activities. Questions about its effectiveness reliability are still posed, making studies this topic desirable. This stud...

Barium titanate (BaTiO3, BTO) ferroelectrics are polar material that exhibits net spontaneous polarization without external applied field [1,2]. The polarization can be reoriented by applying the electric field. BTO with perovskite structure is widely used due to their ferroelectric, pyroelectric and piezoelectric properties in various electronic applications such as multi-layer ceramic capacit...

We present an experimental study on the adsorption behaviour of Intan-100, a nonionic surfactant, at the bitumen/water interface when the density difference between the two phases is increased by diluting the crude oil with 10% Xylene by weight or using heavy water (Deuterium Oxide) as the aqueous phase. Their equilibrium interfacial tension, surface excess and critical micelle concentration of...

Achillea species are widely used for diarrhea, abdominal pain, stomachache and healing of wounds in folk medicine. To evaluate the wound healing activity of the plant, extracts were prepared with different solvents; hexane, chloroform, ethyl acetate and methanol, respectively from the roots of Achillea biebersteinii. Linear incision by using tensiometer and circular excision wound models were e...

This paper compares six phospholipidic monolayers at the water/chloroform interface by performing dilational rheological measurements with a drop tensiometer apparatus. The chosen lipids differ both in their headgroup structure and fatty acyl chain saturation or symmetry. The study concentrated on monolayers formed with DPPC, DPPE, DOPC, DOPE, POPC and POPE. Using a generalized Maxwell rheologi...
