Highly oriented superconducting thick films of Bi 2 Sr 2 CaCu 2 O 8+x have been prepared by low cost spray pyrolysis technique. Aqueous solution containing nitrates of Bi, Sr, Ca, and Cu in the atomic ratio of 2:2:1:2 is sprayed on MgO (100) substrat
A retrospective study of Head-Neck malignancy was conducted at Allahabad over a period of twenty two years from 1975 to 1996. During this period, 5,386 new Head-Neck Cancer cases were reported. Peak presentation of males was in sixth decade and in fe
