Journal ArticleDOI
Pyridazine derivatives and related compounds. Part 13: Synthesis and antimicrobial activity of some pyridazino[3',4':3,4]pyrazolo[5,1-c]-1,2,4-triazines.
TL;DR: A general method for the preparation of substituted pyridazinopyrazolotriazines with substituents such as methyl, phenyl, ethoxycarbonyl, acetyl or benzoyl is reported.
Journal ArticleDOI
Idealization of j-approximation spaces
TL;DR: This work concentrates on generating different topologies by using the concept of the ideal to remove the vagueness of a concept to uncertainty areas at their borders by increasing the lower approximation and decreasing the upper approximation.
Journal ArticleDOI
Pyridazine Derivatives and Related Compounds, Part 17: 1 The Synthesis of Some 3-Substituted Pyridazino[3′, 4′:3, 4]pyrazolo[5, 1-c]-1,2,4-triazines and Their Antimicrobial Activity
TL;DR: The reaction of the hydrazide of pyridazino[3′, 4′:3, 4, 4]pyrazolo[5, 1-c]-1,2,4-triazine-3-carboxylic acid 3 with carbon disulfide in the presence of potassium hydroxide gave the 1,3,4oxadiazole-2-thione derivative as mentioned in this paper.
Journal ArticleDOI
Bi-ideal approximation spaces and their applications
TL;DR: Two kinds of approximation operators via ideals which represent extensions of Pawlak’s approximation operator have been presented and the definitions of upper and lower approximations based on ideals have been given.
