.Energetic ionic liquids compared to conventional high energy compounds, such as TNT, HMX and RDX has a low vapor pressure, high thermal stability and adjustable chemical and physical properties and high being liquid range. A new class of ionic salts that have a large number of nitrogen on their structure have distinctive characteristics such as high heat of formation and high viscosity, comp...

   In this paper, numerical results obtained and explained from an exact formula in relation to sound pressure load due to the presence of liquid inside the finite-length non-rigid carbon nanotubes (CNTs), which is coupled with the dynamic equations of motion for the CNT. To demonstrate the accuracy of this work, the obtained formula has been compared to what has been used by other research...

in this study, a three–layer artificial neural network (ann) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. a total of 455 data points were collected from 13 data sources to develop the ann model. superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of t...

OBJECTIVE The purpose of this study was to optimise the HPLC-UV bio-analytical method currently used by the Salamanca University Clinical Hospital for determining lamotrigine plasma levels. MATERIAL AND METHODS The developed HPLC-UV analytic technique currently in use was shown to be linear, exact and precise, and suitable for use in routine monitoring of lamotrigine levels. The drawback of t...
