Chemical changes in Haden, Irwin, Kent, and Keitt mangos stored at 1628°C and 85-90% RH were followed to determine the optimum storage and ripening conditions. Weight loss was slightly higher at 25" and 28°C than at 16-22°C. Breakdown in acidity during ripening was slower at 16°C. Vitamin C showed two basic trends; a general decrease as in Haden, Irwin, and Keitt or a steady increase as in Kent. Total and B-carotenoids were significantly higher at 22-28°C than at 1620°C. No significant differences were observed with respect to carbohydrate and soluble solids content. However, sucrose increased spectacularly at all temperatures contributing most to the increase in sweetness. The pattern of chemical changes were strikingly similar in all the varieties. Temperatures of 2&22"C and 85-90% RH are recommended for storage and ripening of mangos to obtain sufficiently acceptable quality attributes.

We present a new model of cosmology which appears to show great promise. Our flat space cosmology model, using only four basic and reasonable assumptions, derives highly accurate Hubble parameter H 0 , Hubble radius R 0 and total mass M 0 values for our observable universe. Our model derives a current Hubble parameter of 1.0272646 10 m K × ⋅ ≅ , has been derived, which appears to be an excellent fit for the Planck scale as well as the current observable universe scale. Using the flat space Minkowski relativistic formula for Doppler effect, and a formula for staging our cosmological model according to its average mass-energy density at every Hubble time (universal age) in its expansion, a persuasive argument can be made that the observable phenomena attributed to dark energy are actually manifestations of Doppler and gravitational redshift. Finally, a theory of cosmic inflation becomes completely unnecessary because our flat space cosmology model is always at critical density.

For strong interaction two new fermion mass units 105.32 MeV and 11450 MeV are assumed. Existence of "Integral charge quark bosons", "Integral charge effective quark fermions", "Integral charge (effective) quark fermi-gluons" and "Integral charge quark boso-gluons" are assumed and their masses are estimated. It is noticed that, characteristic nuclear charged fermion is Xs · 105.32 = 938.8 MeV and corresponding charged boson is Xs(105.32/x) = 415.0 where Xs = 8.914 is the inverse of the strong coupling constant and x = 2.26234 is a new number by using which "super symmetry" can be seen in "strong and weak" interactions. 11450 MeV fermion and its boson of mass = 11450/x = 5060 MeV plays a crucial role in "sub quark physics" and "weak interaction". 938.8 MeV strong fermion seems to be the proton. 415 MeV strong boson seems to be the mother of the presently believed 493,496 and 547 MeV etc, strange mesons. With 11450 MeV fermion "effective quark-fermi-gluons" and with 5060 MeV boson "quark boso-gluon masses" are estimated. "Effective quark fermi-gluons" plays a crucial role in ground state charged baryons mass generation. Light quark bosons couple with these charged baryons to form doublets and triplets. "Quark boso-gluons" plays a crucial role in ground state neutral and charged mesons mass generation. Fine and super-fine rotational levels can be given by [I or (I/2)] power(1/4) and [I or (I/2)] power(1/12) respectively. Here, I = n(n+1) and n = 1, 2, 3, ….

Even though 'String theory' models and "quantum gravity' models are having a strong mathematical back ground and sound physical basis, they are failing in implementing the Newtonian gravitational constant in atomic and nuclear physics and thus seem to fail in developing a 'workable' model of final unification. In this context, extending Abdus Salam's old concept of 'nuclear strong gravitational coupling' we consider two very large pseudo gravitational constants assumed to be associated with electromagnetic and strong interactions. By combining the two microscopic pseudo gravitational constants with the Newtonian gravitational constant, we make an attempt to combine the old 'strong gravity' concept with 'Newtonian gravity' and try to understand and re-interpret the constructional features of nuclei, atoms and neutron stars in a unified approach. Finally we make a heuristic attempt to estimate the Newtonian gravitational constant from the known elementary atomic and nuclear physical constants. By exploring the possibility of incorporating the proposed two pseudo microscopic gravitational constants in current unified models, in near future, complete back ground physics can be understood and observable low energy predictions can be made.
