The significance of gamma function and Riemann zeta function in solving such integrals has been studied and functional equations are evaluated thereby enabling the integrals of all orders to be calculated.</p> Akbari Jahan ##submission.copyrightStatement## 2021-01-19 2021-01-19 8 1 1 9 On the Nature of Dark Matter <p>Dark Matter is observed envelloping the galaxies around super massive Black Holes leading to an uniform rotation over most of the galaxy cross-section. It is stipulated that Dark Matter originates from the central super massive black hole. By the fact that the speed of light is close to infinity inside the black hole a halo of virtual particles appear outside the cental black hole through the Heisenberg uncertainity principle. This leads to a correct distribution of the virtual density leading to an uniform rotation of the galaxy.</p> Paul Smeulders ##submission.copyrightStatement## 2021-03-23 2021-03-23 8 1 10 17 Zero field splitting parameter of Mn2+ doped guanidine zinc sulphate crystal -a theoretical study <p>A theoretical investigation of crystal field parameters (CFP) and zero-field splitting (ZFS) parameter D of Mn<sup>2+</sup> doped guanidine zinc sulphate (GZS) crystals at room temperature (RT) is done with the help of superposition model and the perturbation theory. The ZFS parameter D determined here is in good agreement with the experimental value reported earlier. The conclusion of experimental study that Mn<sup>2+</sup> substitutes for Zn<sup>2+</sup> in GZS is supported by our theoretical investigation. The values of D without and with local distortion are 11174.3×10<sup>-4</sup> cm<sup>-1</sup> and 702.4 ×10<sup>-4</sup> cm<sup>-1</sup>, respectively, while the experimental value is 702.0×10<sup>-4</sup> cm<sup>-1</sup>.</p> Ram Kripal Lal Chandra Shukla Upendra Mani Tripathi ##submission.copyrightStatement## 2021-03-29 2021-03-29 8 1 18 23
