The aim of this study was to investigate the efficiency of hydrophilic polymers to enhance the dissolution rate of poorly water-soluble active pharmaceutical ingredients (APIs) processed by hot-melt extrusion (HME). Indomethacin (INM) and famotidine (FMT) were selected as model active substances while polyvinyl caprolactam graft copolymer, soluplus (SOL)(More)
As a part of the study to explore the possible strategy for enhancing the shelf life of mango fruits, we investigated the changes in biochemical parameters and activities of ripening associated enzymes of Ashwina hybrid mangoes at 4-day regular intervals during storage at -10°C, 4°C, and 30 ± 1°C. Titratable acidity, vitamin C, starch content, and reducing(More)
Given the significant concerns regarding carbon emission from the fossil fuels, global warming and energy crisis, the renewable distributed energy resources (DERs) are going to be integrated in the smart grid. This grid can spread the intelligence of the energy distribution and control system from the central unit to the long-distance remote areas, thus(More)
This paper demonstrates a competent rational polynomial method for efficient computational modelling of graphene surface conductivity using compact framework in the finite-difference time domain (FDTD) method that shape out graphene conductivity. The update equations of graphene surface conductivity using the proposed model in compact-FDTD (C-FDTD) method(More)
This paper proposes a modified mathematical model of graphene interband conductivity. The proposed modified model is similar to Drude model that can be easily applied for wideband modelling up to optical frequency range. This model can easily be superimposed with various computational methods especially in the finite difference time domain method (FDTD) for(More)
In this paper, nonorthogonal locally one dimensional finite difference time domain (LOD-NFDTD) method based on curvilinear coordinate system is presented for analyzing electromagnetic scattering from curved conducting structures. A formulation of LOD-NFDTD method for two dimensional problems is provided. In our generalized approached, the non-orthogonal(More)
This paper deals with the electromagnetic (EM) wave propagation modeling in complex tunnel environments. We propose a novel segmented alternating direction implicit finite difference time domain (S-ADI-FDTD) method for modeling the electromagnetic wave propagation inside an electrically large tunnel. The proposed S-ADI-FDTD method reduces the computational(More)
