The incident of 1971 is a historical concern. Both wings of Pakistan were united at the time of the creation of Pakistan but some policies that were adopted after the creation of Pakistan were inadequate to resolve the growing differences between the both wings. Writers are divided regarding the causes of the Fall of Dhaka. Indian involvement has been highlighted frequently and it is also said that East Bengal was on the distance of 1000 km from West Pakistan. Apart from these causes, this study will highlight a new perspective regarding the separation of East Bengal. From 1947 to 1971 the central governments of Pakistan took some measure regarding formulating policies and the policies were not sufficient to bring people of the both wings closer. Thus, the major policies and their consequences would be analysed in this paper. Further, this research would be a new one in a sense that there would be a general description of the policies from both wings.

A function that closely resembles the two-point time-domain Green's function (TDGF) representing the time delays associated with multipath between the two sensors can be recovered by correlating the noise field measured by two sensors. Here, a technique for extracting the TDGF from ambient ocean noise using acoustic vector sensors is presented. Experimental results suggest that the averaging time to extract TDGF is greatly reduced if sound pressure sensors (hydrophones) are replaced by acoustic vector sensors. The direct arrival and bottom bounce arrival were extracted successfully with only 1 min of vertical velocity data, while the bottom bounce arrival was not extracted with even 10 min of sound pressure data.

This work describes an analytical platform based on semi-high-resolution antileishmanial profiling combined with hyphenation of high-performance liquid chromatography - high-resolution mass spectrometry - solid-phase extraction - nuclear magnetic resonance spectroscopy, i.e., semiHR-antileishmanial assay/HPLC-HRMS-SPE-NMR. The platform enables fast pinpointing of HPLC peaks representing Leishmania tropica inhibitors in complex matrices, with subsequent structural identification of targeted inhibitors. Active analytes were cumulatively trapped on SPE cartridges and the structures elucidated by analysis of NMR spectra obtained in the HPLC-HRMS-SPE-NMR mode. This led to the identification of six known compounds 2,4,6-trihydroxyacetophenone-2-O-β-D-glucopyranoside (1), lalioside (2), luteolin-4'-O-β-D-glucopyranoside (3), apigenin-4'-O-β-D-glucopyranoside (4), luteolin (5), and apigenin (6). IC50 of the active compounds were determined with luteolin being the most potent inhibit...

Aim: To investigate the different antileishmanial activities of extracts of Cassia Fistula L., Morus Nigra L. and Ziziphus Jujuba Mill. Methodology: In this method, three (03) plants having concentrations between 500 – 2000 µg/mL were subjected to KWH23 strains of L. tropica in which Standard drug was Amphotericin B and have negative control for 24 – 48 hours. To check the in-vivo studies, plant extract was tested on BALB/c mice (Iqbal et al., 2016). Results: It showed that inhibition (mean) of KWH23 strains at 500, 1000, 1500, 2000 µg/mL after 48 hours were 92.1 ± 0.02, 95.00 ± 0.05, 97.09 ± 0.07 and 98.05 ± 0.05 % respectively. It decreased the lesion size (mean) from 0.8 ± 0.1 mm to 0.40 ± 0.2 mm having significance value p < 0.01 after 8th week, and cure at 200 mg/Kg against intracellular amastigotes in BALB/c mice was 90.00% (95% Cl = 80.05 – 97.00). Conclusion: The result shows that Ziziphus jujuba Mill. leaves possess significant antileishmanial activity.
