  Abstract
  Study the selection of cross sectional areas of radionuclide and its implementation in the medical field like nuclear therapy is the main objective of this work. For the selection of radionuclide cross section, two nuclear reactions (p, n) and (d, 2n) of Rh and Pd were taken. The observation shows the cross sectional area of (d, 2n) is higher than (p, n) during the reaction. Therefore this observation is beneficial for the selection and treatment of infected areas with more safety and accuracy.

  Abstract
  An exhibition of the orbitary motion of the moon associated with the earth is derived. The revolutionary movement of both the earth and the moon present in the ecliptic orbit of the earth in association around the sun is helpful in obtaining the mechanism of the actual path of the moon. In the solar system, the earth has to remain in the elliptical orbit around the sun under its gravitational attractive force. While the moon’s orbit is decided by the gravitational force acting at the same time mutually by the sun, and earth. The gravitational force acted by the sun is responsible for giving an elliptical velocity to the moon to travel behind the earth. In contrast, the gravitational force of earth is responsible for its movement circularly. Both these types of motions are simultaneously imposed on the moon. Because the earth also moves in its orbit. Therefore, the line of gravitational force acting at the resultant position of the moon will go on changing throughout the whole motion. Thus, the moon only follows the earth for remaining associated behind by revolving in a cyclic path in design. The resulted locus of motion is evidenced to occur by repeating a successive parabolic type of path for completing a full cyclic orbit. The distance of the moon in perigee and apogee positions is related with the parabolic type of motion associated with the earth. The extra distance traveled by the moon to follow the earth via going through the cyclic orbit is accomplished with the displacement provided by the vertical component of orbital velocity. This component of velocity is assessed by Newtonian mechanics and is found to be entirely responsible for carrying the moon vertically displaced from the orbit of the ecliptic into the cyclic orbit. The ecliptic velocity provided by the gravity of sun ever remains unchanged with the moon and plays the active role of horizontal component of orbital velocity necessarily required for displacing the moon behind the earth during the whole motion.

  Abstract
  We review free energy evolution of QGP (Quark-gluon plasma) under zero-loop, one loop and two loop corrections in the mean field potential. The free energies of QGP under the comparison of zero-loop and loop corrections of the interacting potential among the quarks, anti-quarks and gluons are shown. We observe that the formation of stable QGP droplet is dependent on the loop corrections with the different parametrization values of fluid. With the increase in the parametrization value, stability of droplet formation increases with smaller size of droplet. This indicates that the formation of QGP droplet can be signified more importantly by the parametrization value like the Reynold number in fluid dynamics. It means that there may be different phenomenological parameter to define the stable QGP droplet when QGP fluid is studied under loop corrections.

  Abstract
  This commentary reflects on the second postulate of special theory of relativity on advent of Michelson-Morley experiment. Of course the experiment could not complete the task doesn’t mean that the velocity of light is not relative though it is finite. The property of the aether or even of vacuum which permits body to have uniform motion without any resistance may play significant role in maintaining the speed of light constant with respect to which is a subject of our investigation and could produce null results in Michelson-Morley experiment. Our attempt is to discover the influence of motion of source on the velocity of light first when both velocities are perpendicular to each other and second when both are parallel. The investigation shows that the light velocity is constant with respect to its source, however, when the source comes in motion; its velocity gets vectorially added to the velocity of light as it happens for all bodies. Moreover the starlight aberration surprisingly supports to the first case which is circumvented yet. In Michelson-Morley experiment, the light source was always rest with respect to the apparatus consequently the speed of light was constant with respect to the apparatus giving no shift in the fringes.
