Artificially fabricated hydroxyapatite (HAP) shows excellent biocompatibility with various kinds of cells and tissues which makes it an ideal candidate for a bone substitute material. In this study, hydroxyapatite nanoparticles have been prepared by using the wet chemical precipitation method using calcium nitrate tetra-hydrate [Ca(NO3)2.4H2O] and di-ammonium hydrogen phosphate [(NH4)2HPO4] as precursors. The composite scaffolds have been prepared by a freeze-drying method with hydroxyapatite, chitosan, and gelatin which form a 3D network of interconnected pores.

The flowering characteristics, fruit set and fruit drop had a positive effect with the various doses of nitrogen and boron. The boron applied @ 50g/plant took minimum days for flowering (81.64 days), maximum fruit set (74.67 %), minimum fruit drop (35.05 %) and days for harvesting (98.86 days). The flowering to harvesting is decreased by 17 days with application of boron @ 50g/plant.

Poly house experiment was carried out at Zonal Agricultural and Horticultural Research Station (ZAHRS), Navile, Shivamogga during kharif2016 to study the response of tomato fruit to different sources and levels of calcium. Three sources of calcium [CaCl2, CaNO3 and calcium ammonium nitrate (CAN)] with three levels each (0.20, 0.50 and 0.80%) were applied as a foliar spray in a Complete Randomized Design (CRD) with three replications and ten treatments.

Secondary aerosol is produced by the oxidation of primary gases (sulphur dioxide, SO2, nitrogen oxides, NOx, and volatile organic compounds, VOCs,) to sulphuric and nitric acid, and organic vapours, followed by their gas-particle conversion [26, 77]. Finally, some of these acidic gases can be neutralised by reaction with ammonia gas or calcium carbonate (calcite) forming secondary aerosol (ammonium sulphate, ammonium nitrate, calcium sulphate, calcium nitrate).
