Research Work on Hydroxyapatites

 Professor Narasaraju wrote numerous research papers on Hydroxyapatite, which is the main inorganic constituent of human bones and teeth. A significant part of his research is on finding ways to use Hydroxylapatite to remove fluorine from drinking water which causes a disease known as Fluorosis. . Ground-water of many areas of the world contains fluorine. Professor Narasaraju and his collaborators did extensive research work as mentioned in his autobiographical account, to explore possibilities of preventing the occurrence of the disease through removal of fluorine using synthetic samples of Hydroixylapatite. The process of removal of fluorine from drinking-water is known as Defluoridation. An exhaustive account of his work appeared as a Review published in the Journal of Materials Science.

Going Down My Memory Lane - Autobiography

 There is a time in one's life, quite late, when one can't help but look back at the way life was in the past years. Dwelling in the old memories which seem a little blurry at times, now becomes a favorite pastime. At that age Professor Narasaraju decided to collect his memories in the form of an autobiography through which the present generation can come to connect with the past, so that the past isn't forgotten and we as the future remember where it all began. Beginning at the ancestral origins of the family, Professor Narasaraju in this autobiographical account has described numerous incidents which shaped him throughout his life, while also giving descriptions of every family member. These reminiscences are priceless for us and the generations beyond to keep us connected to our roots so that we don't forget where we came from.  Going Down My Memory Lane

Prahalada Charitra: A Translation from Potana's Bhagawata Purana

  Prahalada Charitra has been written by many great saints and poets. It has been translated into numerous languages from the original in Sanskrit. Potana was one such enlightened individual whose exceptionally beautiful translation of the Bhagawata puranam holds a high place in the world of Telugu literature.  Professor Narasaraju has translated the Dasamaskandam of Potana's Bhagawatam and now he has moved on to translate the Prahalada Charitra from Telugu to English.  A copy of the translated work is attached below   Prahalada Charitra
