Some tridentate ligands were synthesized by the reaction of ethyl 2-phenylhydrazono-3-oxobutyrate and its derivative with isoniazid by the method reported in literature. The hexacoordinated complexes of Cu(II) and Ni(II) ions with these ligands were synthesized, and characterised on the basis of their electronic, IR absorption properties and magnetic properties. The composition of the complexes were found as [ML2].The analysis shows that after mono deprotonation the ligand 1-isonicotinoyl-3-methyl-4- (phenylhydrazono)-2-pyrazoline-5-one(HL),their methyl derivative HL’ and methoxy derivative HL’’ behaved as tridentate N,N,O donor ligand. The structural studies of metal complexes revealed that each metal ion is hexacoordinated. The electronic spectral band and IR spectral bands have been interpreted.

They are known to be highly toxic to cells, mainly through their action on cell reproduction. Many have proved to be carcinogens, mutagens or teratogens. Patients receiving therapeutic doses of these drugs have exhibited many adverse effects, including cancers. All people who came in contact with cytotoxic drug...

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
