Around 30 female illiterate casual/contractors workers who are working in different divisions and centers of CSIR-NML participated in the program. Literacy campaigns have heightened social awareness among women regarding the importance of education, both for themselves as well as for their children. They have acquired a heightened sense of self-awareness and desire to gain knowledge of host of women’s issues. The program was published in CSIR and local newspapers on monthly basis. https://www.avenuemail.in/jamshedpur/female-literacy-drive-at-nml/134498/  NMD-ATM (2018): Rapporteur for Session of Process Metallurgy (8): Continuous casting
