  • The Possibility of Spontaneous Gravitational Contraction of a Gas Cloud in
           Outer Space with Simultaneous Cooling of the Cloud

    • Abstract: Publication date:  Jun 2018
      Source:Universal Journal of Physics and Application  Volume  12  Number  2  Alexey Belyaev   Gas clouds in outer space always lose energy due to electromagnetic radiation, i.e., are non-isolated thermodynamic systems. Under certain conditions, the energy loss of the gas cloud can lead to replacement of the process of dispersion by the process of spontaneous gravitational compression. Under these conditions of the initiation process of spontaneous compression, the gravitational energy released by the compression of the cloud will correspond to losses due to electromagnetic radiation it experiences. Furthermore, the cloud will shrink with a decrease in internal energy with constant enthalpy. As a result, the process of spontaneous gravitational compression of a gas cloud in outer space will be accompanied by a decrease in the temperature of the cloud. This mechanism of compression of a gas cloud with simultaneous cooling could, at a certain stage of the evolution of the universe, govern one of the possible processes of formation of a hidden mass of galaxies.

  • Space-like Particle Production: An Interpretation Based on the Majorana
           Equation

    • Abstract: Publication date:  Jun 2018
      Source:Universal Journal of Physics and Application  Volume  12  Number  2  Luca Nanni   This study reconsiders the decay of an ordinary particle in bradyons, tachyons and luxons in the field of the relativistic quantum mechanics. Lemke already investigated this from the perspective of covariant kinematics. Since the decay involves both space-like and time-like particles, the study uses the Majorana equation for particles with an arbitrary spin. The equation describes the tachyonic and bradyonic realms of massive particles, and approaches the problem of how space-like particles might develop. This method confirms the kinematic constraints that Lemke's theory provided and proves that some possible decays are more favorable than others are.

  • Effects of Interfacial Layer on Refractive Index and Propagation of Waves
           in Small Spherical Metal/ Dielectric Composite

    • Abstract: Publication date:  Apr 2018
      Source:Universal Journal of Physics and Application  Volume  12  Number  1  Dessalegn Kenate   Sisay Shewamare   and Getnet Melese   In this work we have studied the effect of interfacial layer on the refractive index, and propagation of waves in small spherical metal/dielectric composite separated by interfacial layers which is randomly embedded in a linear dielectric host matrix. The theoretical, and numerical descriptions are in terms of the interfacial factor (I) by incorporating Taylor expansion and Drude model. The result shows that both the interfacial layer property, and the percentage of the volume fraction of the metallic particles in the composite has an effect on the refractive index, and propagation of waves of the composite when the dielectric functions of the interfacial layer is more metal-like property than dielectric-like property.

  • Near-surface Seismic Velocity Model Building from First Arrival
           Travel-times - A Case Study from an Onshore, Niger Delta Field

    • Abstract: Publication date:  Apr 2018
      Source:Universal Journal of Physics and Application  Volume  12  Number  1  Opara, C.   Adizua, O. F.   and Ebeniro, J. O.   Seismic refraction was used to image the near-surface, using a3D seismic data acquired from an onshore Niger Delta field. The objective of the study was to build a near-surface model of the earth in terms of sub-weathering layer thicknesses and seismic wave velocities and highlight the near-surface seismic wave velocity variation in the region. A velocity-depth model consisting of the weathering layer and three consolidated (sub-weathering) layers was first estimated. The first-breaks were picked and used as input for this study. The models were generally consistent in terms of their large-scale features, demonstrating the robustness of refraction data inversion in general. Results support confidence in the reliability and robustness of the refraction inversion method. The method of analysis and resolution for 3-layer models adopted in this study may be used in resolving such cases observed during processing of seismic reflection data from the Niger-Delta Basin.
