The results indicated that the antimicrobial activity was dependent on the type of the Schiff base moiety. Facebook gives people the power to share and makes the world more open and connected.

The Schiff bases were screened for their biological activity against gram-negative bacteria (Escherichia coli and Klebsiella pneumonia), gram-positive bacteria (Staphylococcus aureus and Streptococcus mutans) and fungi (Asperagillus fumigatus and Candida albican). In view of the severe environmental pollution caused by plastic food packaging, there is a considerable interest in edible and biodegradable films made from renewable and natural polymers. 4- Why didnt Alaa Wali El-Dins corpse decompose after all this time Nineteen years after comedy star Alaa Wali El-Dins passing. This paper addresses the seismic analysis of a real massive deeply embedded structure, a structural typology traditionally analysed with the three-step approach, the objective being the assessment of the motion at discrete points of the structure consistent with a given free field ground motion.

All newly synthesized compounds have been characterized by solubility tests, elemental analysis, spectral (FTIR, 1H NMR) analyses, thermogravimetric analysis and X-ray diffraction (XRD). Three heteroaryl pyrazole derivatives namely 1-phenyl-3-(thiophene-2-yl)-1H-pyrazole-4-carbaldehyde, 1-phenyl-3-(furan-2-yl)-1H-pyrazole-4-carbaldehyde and 1-phenyl-3-(pyridine-3-yl)-1H-pyrazole-4-carbaldehyde were synthesized and reacted with chitosan to form Schiff bases of chitosan.
