Large scale flows in the solar interior: Effect of asymmetry in peak profiles

Ring diagram analysis can be used to study large scale velocity fields in the outer part of the solar convection zone. All previous works assume that the peak profiles in the solar oscillation power spectrum are symmetric. However, it has now been demonstrated that the peaks are not symmetric. In this work we study how the explicit use of asymmetric peak profiles in ring-diagram analysis influences the estimated velocity fields. We find that the use of asymmetric profiles leads to significant improvement in the fits, but the estimated velocity fields are not substantially different from those obtained using a symmetric profile to fit the peaks. The resulting velocity fields are compared with those obtained by other investigators.Comment: To appear in Ap

Applications of Hellmann-Feynman Theorem (HFT) to Angle Dependent Yukawa Potential of Diatomic Molecules

We have applied Hellmann-Feynman Theorem (HFT) to the bound state solutions of angle dependent Yukawa potential model for five selected diatomic molecules..

Antiulcerogenic activity of ethanolic leaf extract of Lasianthera africana

The effect of ethanolic leaf extract of Lasianthera africana on experimentally induced ulcer was studied in rats. The extract (1000 – 3000mg/kg) inhibited ethanol-induced, indomethacin – induced and reserpine –induced ulcer models in a dose dependent fashion. The various degrees of inhibitions were statistically significant (

Phytochemistry, antibacterial and anticoagulase activities of Sida acuta against clinical isolates of Staphylococcus aureus

oai:journals.ansfoundation.org:article/20The phytochemical, antibacterial and anticoagulase activities of Sida acuta against clinical isolates of Staphylococcus aureus were investigated. The phytochemistry of the plant leaves revealed that S. acuta is laden with antioxidative compounds with remarkable concentrations of saponins (0.772 mg/100g), flavonoids (0.112 mg/100g), alkaloids (0.076 mg/100g) and tannins (0.0541mg/100g). Their presence conferred a strong bactericidal effect on Staphylococcus aureus SS-1VC, Staph. aureus SS-2VM, Staph. aureus SS-3SW, Staph aureus SS-4OM, Staph. aureus SS-5BC Staph. aureus SS-6AF and Staph. aureus SS-7DS isolated from vaginal candidiosis, vaginal mycosis, septic wound, otitis media, buccal cavity, athletes foot and diarrheic stool respectively. Majority of the bacterium strains screened were sensitive to aqueous and methanol extracts of S. acuta leaves. All the strains were inhibited by the aqueous extract, but more susceptible were strains SS-2VM isolated from vaginal mycoses and SS-3SW from septic wound, which recorded 25mm and 24mm diameter of inhibition zones respectively, after treatment with 8.0mg/ml of the extract. However, much lower concentration (0.5mg/ml) of the extract was required to halt coagulase activity in both strains. The methanol leaf extract exhibited similar but stronger antibacterial and anticoagulase activities against the clinical isolates of Staph. aureus. Marked antibacterial inhibitory effects were observed against most strains tested but SS-6AF and SS-7DS (which exhibited comparatively lower susceptibility), with majority of the strains losing theiranticoagulase producing potential at concentrations as low as 0.5mg/ml of alcoholic extract. The strong anticoagulase activity of S.acuta, and it’s efficacy in inhibiting coagulase elaboration by Staph aureus especially Staph. aureus SS3SW isolated from septic wound forms the basis of it’s use in folk medicine for wound treatment

Energy – Momentum of the Armenian Special Relativity Theory

In this paper, the energy and momentum of the Armenians Special Relativity Theory (ASRT) and Special Relativity Theory (SRT) are obtained and their comparison is also carried out. SRT through the Muhelson-Morlay experiment proved that aether does not exist in space, but ASRT reincarnates the aether as a universal reference medium. The mathematical existence of aether has already been proven. In his work, by comparing energy and momentum of both SRT and ASRT, the results obtained indicate that difference is  in the time-space or subatomic aether medium which is represented by space coefficient  and geometrical space . The theory brings together followers of absolute aether theory, relativistic aether theory and the dark matter theory. The energy and momentum in SRT can be deduced from ASRT by substituting  and . This implies that, SRT is a limiting case of ASRT. Keywords: Relativistic theory, Rest Particle, Dark Energy, Armenian Theor

Non-Relativistics Treatment of Schrodinger Particle under Modified Inversly Quadratic Hellmann Potential Model Via Parametric N-U Method

The non-relativistics study of particles under the modified inversely quadratic Hellmann potential has been studied. The energy eigenvalues and the corresponding wavefunction expressed in terms of the Jacobi polynomial are obtained using the parametric NU method. In obtaining the solutions for this system, we have used an approximation scheme to evaluate the centrifugal term (potential barrier). To test the accuracy of our result, we compared the approximation scheme with the centrifugal term and the result shows that there is an agreement between the centrifugal term and the approximation scheme for a very small screening parameter; showing that our potential is a short range potential. The results obtain from this work, would have many application in inner shield ionization problem, Electron core, Solid state Physics, Alkali-Hydride molecules. Three special cases of this potential have also been discussed
