Agriculture has always been the mainstay of our people and we have been tilling the land and reaping the harvests for hundreds of years. This naturally found us in a situation where the land was becoming less and less bountiful. The yield was getting lower and lower and in the early half of 20th century we found we had to depend on imports to meet out minimum food grain requirement.

The utility of carbonate apatite (CO3Ap) as a bone substitute has been demonstrated. The feasibility of fabricating macroporous CO3Ap was evaluated through a two-step dissolution–precipitation reaction using gypsum as the precursor and spherical phenol resin as the porogen. Porogen-containing gypsum was heated to burn out the porogen and to fabricate macroporous structures.
