    Mother Goddess Worship in Cultural Change

    Get PDF
    Mother Goddess worship plays an important role in bringing about a great change in culture. Women are prioritized in determining relationships, property rights, and marriage. Literature and historical documents confirm this, sculptures and inscriptions have been found in Tamil Nadu to show that Isakhyamman was a female deity during the Jain period. The practice of worshiping them under many names as household deities, ethnic deities, clan deities, village deities, guardian deities, boundary deities, and tribal deities has been going on since then till today

    Literary Feminism and Psychology towards Gender Equality

    Get PDF
    The society denied women's place, rights, labor and even her existence. A woman's social participation is followed by her self-need and self-seeking being fulfilled even if she thinks and questions equally and not against men. In order to prevent this effort, variations were created in education, scriptures and arts training. In this society, women took the lead as a slave and as a second class human being. Literature, myths and religions were suppressed in the corner of the house in the kitchen. Even when she tried to fly with a small wing, he tied a rope called chastity and held the end of the rope in his hand and tried to pull it. This article's purpose is to tell the readers to create a better society where both the gender are treated equally and given equal knowledge

    Stress tensor for a scalar field in a spatially varying background potential: Divergences, "renormalization," anomalies, and Casimir forces

    Motivated by a desire to understand quantum fluctuation energy densities and stress within a spatially varying dielectric medium, we examine the vacuum expectation value for the stress tensor of a scalar field with arbitrary conformal parameter, in the background of a given potential that depends on only one spatial coordinate. We regulate the expressions by incorporating a temporal-spatial cutoff in the (imaginary) time and transverse-spatial directions. The divergences are captured by the zeroth- and second-order WKB approximations. Then the stress tensor is "renormalized" by omitting the terms that depend on the cutoff. The ambiguities that inevitably arise in this procedure are both duly noted and restricted by imposing certain physical conditions; one result is that the renormalized stress tensor exhibits the expected trace anomaly. The renormalized stress tensor exhibits no pressure anomaly, in that the principle of virtual work is satisfied for motions in a transverse direction. We then consider a potential that defines a wall, a one-dimensional potential that vanishes for z<0z<0 and rises like zαz^\alpha, α>0\alpha>0, for z>0z>0. The full finite stress tensor is computed numerically for the two cases where explicit solutions to the differential equation are available, α=1\alpha=1 and 2. The energy density exhibits an inverse linear divergence as the boundary is approached from the inside for a linear potential, and a logarithmic divergence for a quadratic potential. Finally, the interaction between two such walls is computed, and it is shown that the attractive Casimir pressure between the two walls also satisfies the principle of virtual work (i.e., the pressure equals the negative derivative of the energy with respect to the distance between the walls).Comment: 20 pages, 6 figure

    Supersymmetric quantum mechanics and the Riemann hypothesis

    Full text link
    We construct a supersymmetric quantum mechanical model in which the energy eigenvalues of the Hamiltonians are the products of Riemann zeta functions. We show that the trivial and nontrivial zeros of the Riemann zeta function naturally correspond to the vanishing ground state energies in this model. The model provides a natural form of supersymmetry.Comment: 5 pages, 1 figur

    Spin and exchange coupling for Ti embedded in a surface dipolar network

    We have studied the spin and exchange coupling of Ti atoms on a Cu2_2N/Cu(100) surface using density functional theory. We find that individual Ti have a spin of 1.0 (i.e., 2 Bohr Magneton) on the Cu2_2N/Cu(100) surface instead of spin-1/2 as found by Scanning Tunneling Microscope. We suggest an explanation for this difference, a two-stage Kondo effect, which can be verified by experiments. By calculating the exchange coupling for Ti dimers on the Cu2_2N/Cu(100) surface, we find that the exchange coupling across a `void' of 3.6\AA\ is antiferromagnetic, whereas indirect (superexchange) coupling through a N atom is ferromagnetic. We confirm the existence of superexchange interactions by varying the Ti-N angle in a model trimer calculation. For a square lattice of Ti on Cu2_2N/Cu(100), we find a novel spin striped phase

    Spontaneous Symmetry Breaking in Presence of Electric and Magnetic Charges

    Starting with the definition of quaternion gauge theory, we have undertaken the study of SU(2)_{e}\times SU(2)_{m}\times U(1)_{e}\times U(1)_{m} in terms of the simultaneous existence of electric and magnetic charges along with their Yang - Mills counterparts. As such, we have developed the gauge theory in terms of four coupling constants associated with four - gauge symmetry SU(2)_{e}\times SU(2)_{m}\times U(1)_{e}\times U(1)_{m}. Accordingly, we have made an attempt to obtain the abelian and non - Abelian gauge structures for the particles carrying simultaneously the electric and magnetic charges (namely dyons). Starting from the Lagrangian density of two SU(2)\times U(1) gauge theories responsible for the existence of electric and magnetic charges, we have discussed the consistent theory of spontaneous symmetry breaking and Higgs mechanism in order to generate the masses. From the symmetry breaking, we have generated the two electromagnetic fields, the two massive vector W^{\pm} and Z^{0} bosons fields and the Higgs scalar fields

    Pomegranate – an Insight into its Antioxidative, Thrombolytic and Membrane Stabilizing Property

    Get PDF
    The present study is focused on exploring the antioxidative, thrombolytic and membrane stabilizing property of the peel and aril of pomegranate. Antioxidative property was deliberated based on their free radical scavenging ability in which the peel exerted higher radical scavenging potential. Thrombolytic potential of pomegranate was notably higher in aril (30.36%) than in peel (27.62%) while the standard streptokinase exhibited 58.38%. The membrane stabilizing activity was assessed under hypotonic and varying temperature conditions and compared with standard acetyl salicylic acid. The synergistic effect of the fruit could be further explored to be one of the best sources for atherothrombotic diseases.
