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)
This paper presents a comparative performance analysis of Inverted F antenna using various substrates. Natural cork, Plastic and Wood plastic are used as its substrate and the results are compared with the results of using FR4 substrate. This antenna is simulated using Ansoft's HFSS software. The antenna performances are also analyzed using different widths(More)
Dhaka and its neighboring areas suffer from severe air pollution, especially during dry season (November-April). We investigated temporal and directional variations in particulate matter (PM) concentrations in Dhaka, Gazipur, and Narayanganj from October 2012 to March 2015 to understand different aspects of PM concentrations and possible sources of high(More)
Due to dramatically rising energy demand worldwide power system is often run near the operational and technical limits, where unexpected trivial disturbances can cause possibly massive blackouts. Cyber attacks on smart grid communication networks are one of the impending threats to cause large-scale cascading outage. In contrast to the traditional cyber(More)
