Physical and mechanical properties of the drug-incorporated polymer play a significant role in release behavior from drug carriers. Understanding relative extent variation physical makes it possible to improve design carriers obtain better profile increase stability. Drug delivery PLGA loaded with various percentages diclofenac sodium (DS: 0, 5%, 10%) at different flow rates 0 7.5 ml/s (flow ra...
The nanoindentation experiment was carried out to estimate nanomechanical characteristics of polycarbonate polymer films. Hardness, effective elastic modulus and contact stress–strain rate curve were obtained. The results showed that the effective elastic modulus and the hardness decreased as the applied load was increased. As the hold time was increased, the effective elastic modulus and the h...
The authors present a simple elastostatic approach to estimate a suitable subgrade modulus from falling weight deflectometer (FWD) data. An effective surface modulus is defined on the basis of Boussinesq-Newmark equations. Deviations between the model assumptions and actual in situ conditions are reflected in the effective surface modulus variation with radius. The variation indicates which sen...
Low modulus, compliant systems of sensors, circuits and radios designed to intimately interface with the soft tissues of the human body are of growing interest, due to their emerging applications in continuous, clinical-quality health monitors and advanced, bioelectronic therapeutics. Although recent research establishes various materials and mechanics concepts for such technologies, all existi...
We develop the helicity modulus as a criterion for superconducting order in the mixed phase of a fluctuating type II superconductor. We show that there is a duality relation between this helicity modulus and the superfluid density of a system of analog 2D bosons. We show that the vortex line lattice exhibits a perfect Meissner effect with respect to a shearing perturbation of the applied magnet...
This study contributes to the preliminary development of active food packaging materials by using bio-based polymers under ultrasonic waves. For this alginate (Algi) polymer was reinforced with functionalized multiwalled carbon nanotubes (COOH-MWCNTs) dispersed in surfactants form A-type films. Similarly, a B-type films, Algi blended polyvinyl alcohol (PVA) presence COOH-MWCNTs. The synthesized...
Assume that the local compliance tensor of an elastic composite in two space dimensions is equal to a rank-one tensor plus a null-Lagrangian (there is only one symmetric one in 2D). The purpose of this paper is to prove that the effective compliance tensor has the same representation: rank-one plus the null-Lagrangian. This statement generalizes the well-known result of Hill [14, 15] that a com...
