CONCEPT OF AHARA (DIET) IN AYURVEDA: A CRITICAL REVIEW

Ahara is first among the three significant pillars of Ayurveda. It means that it is one of the fundamental principles ahead which gives health, happiness and harmony along with the nature. One should regularly take such substances which are conductive to the preservation of good health and are able of avoid the attacks of sickness. Such type of diet is called naturally healthy diet. Ayurveda is science of life. Main aim of Ayurveda is to maintain health of a person. Ahara plays importance role to achieve this target. In the modern times, the ways in which the food is prepared and presented have changed drastically. Because of the rapid swiftness of life style towards urbanization, one can have less access to fresh food. Today, the dependency on packaged and processed food has also increased exceptionally. It definitely has some destructive effect on both mental and physical well-being. Today Due to consumption of unwholesome diet society facing so many types of disease. Here the concept of Ahara according to Ayurveda is described.

Time-Fractional KdV Equation: Formulation and Solution using Variational Methods

In this work, the semi-inverse method has been used to derive the Lagrangian of the Korteweg-de Vries (KdV) equation. Then, the time operator of the Lagrangian of the KdV equation has been transformed into fractional domain in terms of the left-Riemann-Liouville fractional differential operator. The variational of the functional of this Lagrangian leads neatly to Euler-Lagrange equation. Via Agrawal's method, one can easily derive the time-fractional KdV equation from this Euler-Lagrange equation. Remarkably, the time-fractional term in the resulting KdV equation is obtained in Riesz fractional derivative in a direct manner. As a second step, the derived time-fractional KdV equation is solved using He's variational-iteration method. The calculations are carried out using initial condition depends on the nonlinear and dispersion coefficients of the KdV equation. We remark that more pronounced effects and deeper insight into the formation and properties of the resulting solitary wave by additionally considering the fractional order derivative beside the nonlinearity and dispersion terms.Comment: The paper has been rewritten, 12 pages, 3 figure

In vitro micropropagation and ex vitro acclimation of Bupleurum kaoi - An endangered medicinal plant native to Taiwan

This study reports an improved protocol for in vitro-shoot multiplication and ex vitro acclimation of Bupleurum kaoi, an endangered medicinal herb. Nodal segments were cultured in half-strength Murashige and Skoog (MS) basal medium supplemented with different concentrations of benzyladenine (BA) and kinetin. The presence of 0.25 mg l(-1) BA induced the highest number of shoots per explant after 8 wk of culture. Although BA was more effective than kinetin on shoot multiplication, it induced hyperhydric shoots at all concentrations tested. The use of dispense paper (DP) instead of aluminum foil (AF) for container closure was found to reduce hyperhydricity and improve ex vitro acclimation. The best survival rate (61%) was obtained when plantlets were grown in MS basal medium containing 0.5 mg l(-1) indole-3-butyric acid and 0.1-0.2 mg l(-1) alpha-naphthaleneacetic acid using DP as container closure. Leaves of the plant treated with AF6 (two layers of AF as container closure and 6 wk of incubation) lacked epicuticular wax and possessed larger stomata, higher stomata density, and fewer functional stomata compared to those of plants treated with AF2+DP4 (two layers of AF for 2 wk, then replaced AF by three layers of DP for 4 wk) and ex vitro-acclimated plantlets

Solitons of two-component Bose-Einstein condensates modulated in space and time

In this paper we present soliton solutions of two coupled nonlinear Schodinger equations modulated in the bspace and time. The approach allows us to obatin solitons with large variety of solutions depending on the nonlinearity and the potential profiles. As examples we show three cases with soliton solution in such system, one of them with potential varying between repulsive and attractive behavior and the others with nonlinearity localized and delocalized, respectively.Comment: 18 pages, 8 figure

Spatial gradients in the cosmological constant

It is possible that there may be differences in the fundamental physical parameters from one side of the observed universe to the other. I show that the cosmological constant is likely to be the most sensitive of the physical parameters to possible spatial variation, because a small variation in any of the other parameters produces a huge variation of the cosmological constant. It therefore provides a very powerful {\em indirect} evidence against spatial gradients or temporal variation in the other fundamental physical parameters, at least 40 orders of magnitude more powerful than direct experimental constraints. Moreover, a gradient may potentially appear in theories where the variability of the cosmological constant is connected to an anthropic selection mechanism, invoked to explain the smallness of this parameter. In the Hubble damping mechanism for anthropic selection, I calculate the possible gradient. While this mechanism demonstrates the existence of this effect, it is too small to be seen experimentally, except possibly if inflation happens around the Planck scale.Comment: 12 page

Rare KK Decays

The rare decays of the $K$ meson have had a long tradition as a laboratory for testing the symmetry properties of the weak interactions, and the manner in which these symmetries are broken by higher order effects. Present--day interest is focussed on decays that are suppressed by $CP$--symmetry or GIM symmetry. Such decays, in the standard theory, are sensitive to effects of the virtual top quark, and could also reveal new interactions transcending the standard model. In addition, the radiative decays of the $K$ meson have become a useful testing--ground for effective Lagrangians describing the low energy interactions of pions, kaons and photons.Comment: Invited Talk at the Third Workshop on High Energy Particle Physics (WHEPP 3) Madras, 1994, LaTex, 14 pages, 3 figures available upon reques
