A CLINICAL STUDY TO EVALUATE THE EFFECT OF SHANKHPUSHPYADI YOGA IN THE MANAGEMENT OF VYANBALVRIDDHI W.S.R. TO HYPERTENSION

Changing lifestyle is responsible for increase in number of people suffering from Hypertension, Stress, Diabetes mellitus, Obesity, Heart ailments and other Non Communicable diseases. Among these life-style disorders hypertension is an important public health challenge worldwide. The disease Hypertension has no such clear cut reference in Ayurvedic texts. Eminent Ayurvedic scholar Vaidhya Brihaspati Dev Triguna Padam Vibhushan correlated high blood pressure with Vyana BalaVridhi. He postulated that increased Vyana Bala is responsible for increased Arterial pressure. Present study was conducted to explore evidence based therapeutic potential of Shankhpushpyadi Yoga in the management of Vyan Bal Vriddhi w.s.r. to Hypertension. The patients fulfilling the inclusion criteria and voluntarily wiling for trial were registered from O.P.D. & I.P.D. Dept. of Kayachikitsa R.G.G.P.G.AYU Hospital, Paprola. The Clinical trial was approved by I.E.C. The trial formulation contains Hydroalcoholic extract of Shankhpushpi 150 mg, Bhumyamlaki 250 mg, Punarnava 200 mg, Jatamanshi and Sarpagandha 100 mg each.  Clinical trial was of 45 days and total 30 patients were registered for the same.After45days analysis revealed that out of 30 patients, 4 patients showed excellent improvement,15 showed marked, 7 showed mild improvement and no improvement was noted in 2 patients. The mean systolic blood pressure before treatment was 148.71 mm of Hg which dropped to 140.14 mm of Hg at the end of 45 days therapy, with 5.28% reduction. The mean diastolic blood pressure before treatment was 95 mm of Hg which dropped to 87.142 mm of Hg at completion of trial with 8.27% reduction which was statistically significant.  Shankhpushpyadi yoga proved to be an effective and safe remedy for patients of Hypertension.&nbsp

Chemoreceptor Sensitivity ‘in Women Mountaineering Trainees of Different Altitudes Inducted by Trekking to 4350 m

This study was conducted on women mountaineering trainees to evaluate the hypoxic and hypercapnic ventilatory responses, and the precise nature of changes in the sensitivity of chemoreceptors on induction by trekking to 4350 m. Two groups of women belonging to different ethnic origins and residents of different altitudes, ie, moderate-altitude women (MAWMongolians) and low-altitude women (LAW-Caucasians) were the subjects in this study. Tests of sensitivity to hypoxia and hypercapnia were carried out initially at 2100 m, then during 4 to7 days of sojourn at 4350 m following induction by trekking, and re-tested on return to 2 100 m. The results indicate that there is a significant difference (P c 0.05) of hypoxic ventilatory response in women of two different ethnic groups: Both hypoxic and hypercapnic ventilatory responses increased significantly (P < 0.05) on induction to high altitude. On descent, hypoxic values reverted back to pre-induction levels, whereas hypercapnic ventilatory response showed relatively higher values (P < 0.05)

Computer program for the relativistic mean field description of the ground state properties of even-even axially deformed nuclei

A Fortran program for the calculation of the ground state properties of axially deformed even-even nuclei in the relativistic framework is presented. In this relativistic mean field (RMF) approach a set of coupled differential equations namely the Dirac equation with potential terms for the nucleons and the Glein-Gordon type equations with sources for the meson and the electromagnetic fields are to be solved self-consistently. The well tested basis expansion method is used for this purpose. Accordingly a set of harmonic oscillator basis generated by an axially deformed potential are used in the expansion. The solution gives the nucleon spinors, the fields and level occupancies, which are used in the calculation of the ground state properties.Comment: 18 pages, LaTex, 6 p.s figures, To appear in Comput.

The nuclear shell effects near the r-process path in the relativistic Hartree-Bogoliubov theory

We have investigated the evolution of the shell structure of nuclei in going from the r-process path to the neutron drip line within the framework of the Relativistic Hartree-Bogoliubov (RHB) theory. By introducing the quartic self-coupling of $\omega$ meson in the RHB theory in addition to the non-linear scalar coupling of $\sigma$ meson, we reproduce the available data on the shell effects about the waiting-point nucleus $^{80}$Zn. With this approach, it is shown that the shell effects at N=82 in the inaccessible region of the r-process path become milder as compared to the Lagrangian with the scalar self-coupling only. However, the shell effects remain stronger as compared to the quenching exhibited by the HFB+SkP approach. It is also shown that in reaching out to the extreme point at the neutron drip line, a terminal situation arises where the shell structure at the magic number is washed out significantly.Comment: 18 pages (revtex), 8 ps figures, to appear in Phys.

Analyzing Performance for Generating Power with Renewable Energy Source using Rice Husk as an Alternate Fuel

Energy demand is increasing continuously due to sharp growth in population and industrial development. The development and installation of energy sources are not keeping pace with spiraling demand of energy. Although energy production has increased manifold but still there is big gap between production and demand. The major energy demand is met by conventional energy sources like coal, petroleum, diesel, and natural gas etc. This causes depletion of fossil fuel reserve and environmental pollution. The use of fossil fuel not only causes environmental impact but also energy security problem. Energy from biomass is renewable energy, being looked at as an alternative of fossil fuel. One of the biomass energy sources is rice husk, which is a very promising renewable energy source as it is indigenous and has environmental benefits. However, the environmental and financial profiles of the electricity generation from biomass must be assessed to ensure reduction in greenhouse gas emission and positive cash flow. Environmental impact potential from rice husk is generally lesser than fossil fuel plants. A dual fuel diesel engine-generation of 800 kW, using rice husk gasifier, is considered for the analysis purpose.

Superheavy Nuclei in the Relativistic Mean Field Theory

We have carried out a study of superheavy nuclei in the framework of the Relativistic Mean-Field theory. Relativistic Hartree-Bogoliubov (RHB) calculations have been performed for nuclei with large proton and neutron numbers. A finite-range pairing force of Gogny type has been used in the RHB calculations. The ground-state properties of very heavy nuclei with atomic numbers Z=100-114 and neutron numbers N=154-190 have been obtained. The results show that in addition to N=184 the neutron numbers N=160 and N=166 exhibit an extra stability as compared to their neighbors. For the case of protons the atomic number Z=106 is shown to demonstrate a closed-shell behavior in the region of well deformed nuclei about N=160. The proton number Z=114 also indicates a shell closure. Indications for a doubly magic character at Z=106 and N=160 are observed. Implications of shell closures on a possible synthesis of superheavy nuclei are discussed.Comment: 29 pages Latex, 13 ps figures, to appear in Nucl. Phys.

Generator Coordinate Calculations for the Breathing-Mode Giant Monopole Resonance in Relativistic Mean Field Theory

The breathing-mode giant monopole resonance (GMR) is studied within the framework of the relativistic mean-field theory using the Generator Coordinate Method (GCM). The constrained incompressibility and the excitation energy of isoscalar giant monopole states are obtained for finite nuclei with various sets of Lagrangian parameters. A comparison is made with the results of nonrelativistic constrained Skyrme Hartree-Fock calculations and with those from Skyrme RPA calculations. In the RMF theory the GCM calculations give a transition density for the breathing mode, which resembles much that obtained from the Skyrme HF+RPA approach and also that from the scaling mode of the GMR. From the systematic study of the breathing-mode as a function of the incompressibility in GCM, it is shown that the GCM succeeds in describing the GMR energies in nuclei and that the empirical breathing-mode energies of heavy nuclei can be reproduced by forces with an incompressibility close to $K = 300$ MeV in the RMF theory.Comment: 27 pages (Revtex) and 5 figures (available upon request), Preprint MPA-793 (March 1994

Classes of exact Einstein-Maxwell solutions

We find new classes of exact solutions to the Einstein-Maxwell system of equations for a charged sphere with a particular choice of the electric field intensity and one of the gravitational potentials. The condition of pressure isotropy is reduced to a linear, second order differential equation which can be solved in general. Consequently we can find exact solutions to the Einstein-Maxwell field equations corresponding to a static spherically symmetric gravitational potential in terms of hypergeometric functions. It is possible to find exact solutions which can be written explicitly in terms of elementary functions, namely polynomials and product of polynomials and algebraic functions. Uncharged solutions are regainable with our choice of electric field intensity; in particular we generate the Einstein universe for particular parameter values.Comment: 16 pages, To appear in Gen.

The structure of superheavy elements newly discovered in the reaction of 86^{86}Kr with 208^{208}Pb

The structure of superheavy elements newly discovered in the $^{208}$Pb($^{86}$Kr,n) reaction at Berkeley is systematically studied in the Relativistic Mean Field (RMF) approach. It is shown that various usually employed RMF forces, which give fair description of normal stable nuclei, give quite different predictions for superheavy elements. Among the effective forces we tested, TM1 is found to be the good candidate to describe superheavy elements. The binding energies of the $^{293}$118 nucleus and its $\alpha-$decay daughter nuclei obtained using TM1 agree with those of FRDM within 2 MeV. Similar conclusion that TM1 is the good interaction is also drawn from the calculated binding energies for Pb isotopes with the Relativistic Continuum Hartree Bogoliubov (RCHB) theory. Using the pairing gaps obtained from RCHB, RMF calculations with pairing and deformation are carried out for the structure of superheavy elements. The binding energy, shape, single particle levels, and the Q values of the $\alpha-$decay $Q_{\alpha}$ are discussed, and it is shown that both pairing correlation and deformation are essential to properly understand the structure of superheavy elements. A good agreement is obtained with experimental data on $Q_{\alpha}$. %Especially, the atomic number %dependence of $Q_{\alpha}$ %seems to match with the experimental observationComment: 19 pages, 5 figure

Microscopic Description of Super Heavy Nuclei

The results of extensive microscopic Relativistic Mean Field (RMF) calculations for the nuclei appearing in the alpha - decay chains of recently discovered superheavy elements with Z = 109 to 118 are presented and discussed. The calculated ground state properties like total binding energies, Q values, deformations, radii and densities closely agree with the corresponding experimental data, where available. The double folding (t-rho-rho) approximation is used to calculate the interaction potential between the daughter and the alpha, using RMF densities along with the density dependent nucleon - nucleon interaction (M3Y). This in turn, is employed within the WKB approximation to estimate the half lives without any additional parameter for alpha - decay. The half lives are highly sensitive to the Q values used and qualitatively agree with the corresponding experimental values. The use of experimental Q values in the WKB approximation improves the agreement with the experiment, indicating that the resulting interaction potential is reliable and can be used with confidence as the real part of the optical potential in other scattering and reaction processes.Comment: Accepted for publication in Annals of Physics (NY
