A Novel Indicator to Predict the Onset of Instability of a Gravitational Flow on a Slope

In order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. These points are obtained by means of the solution of the two-dimensional Navier-Stokes equations via the standard Arakawa-C finite-difference method. Results show that in the marginal Richardson numbers, the critical...

Graphic design for scientists.

In 1611, Galileo Galilei created an astonishing series of drawings depicting the Earth’s moon to demonstrate the power of his new invention — the telescope — to his patron, Cosimo de’ Medici1. As a true Renaissance man, Galileo had a degree in drawing from the Accademia delle Arti del Disegno in Florence, as well as a degree in natural philosophy from the University of Pisa. This key connection...

Effect of Thermocline Formation on Underwater Acoustic Waves Propagation in Persian Gulf

Thermocline layer have remarkable effects on acoustic propagation in Persian Gulf environment. So far, no comprehensive research has been conducted to explore thermocline layer, especially its characteristics including top, thickness, and thermal gradient of thermocline in Persian Gulf. Besides, effects of thermocline on underwater acoustic propagation including transmission loss and sound chan...

Preparation of protein-loaded PLGA-PVP blend nanoparticles by nanoprecipitation method: entrapment, Initial burst and drug release kinetic studies

Objective(s):Despite of wide range applications of polymeric nanoparticles in protein delivery, there are some problems for the field of protein entrapment, initial burst and controlled release profile.   Materials and Methods: In this study, we investigated the influence of some changes in PLGA nanoparticles formulation to improve the initial and controlled release profile. Selected parameters ...
