Following the fourth target of United Nations’ Sustainable Development Goals (SDGs), education disparity is one graver concerns delaying substantial economic development, especially in emerging market-based nations. Despite numerous efforts to address this disparity, it has been a long-standing concern for many communities. It important note that recent pandemic changed teaching and learning ap...

This paper presents a simple method that reduces the problem of detecting conflictfree assumption-based knowledge bases to the problem of testing satisfiability.

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

Abstract In nonlinear greedy approximation theory, bidemocratic bases have traditionally played the role of dualizing democratic, greedy, quasi-greedy, or almost bases. this article we shift viewpoint and study them for their own sake, just as would with any other kind greedy-type particular show that need not be despite fact they retain a strong unconditionality flavor which brings very close ...

substituted schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. on cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...
