Information on medicinal claims was collected from the tribal people called 'Sahariya' and the traditional healers who had knowledge of the traditional uses of medicinal plants. This study describes details of botanical identity, local name, parts of the plants used, mode of preparation, administration of the drug, and diseases for which the given plants are used.

The model was based on the finite-difference method of solution and accounted for the kinetics of the combustion process. The parameters were block size, dimensionality of the model, number of reactions, activation energy, reaction constant, and injection rate. About 50 dry-combustion simulation runs were made using the model in one-, two-, and three-dimensional (1D, 2D, and 3D) modes. The chemical properties for a heavy oil were used. In general, runs were carried out for 6,000 days. The output results were cumulative oil production, oxygen consumption, peak temperature, injection bottomhole pressure (BHP), WOR, GOR, heat release from reactions, fuel consumptions, and saturation distribution. The results were most sensitive to the flow convection parameters, such as block size and dimensionality. Kinetic parameter effects were not as significant as previously thought. Moreover, the investigation identified practical difficulties in running a kinetic-based model. Numerical distortion of the convection effects with large grid blocks limits the utility of such models. A brief discussion of a possible method to overcome some of the difficulties is given.

(Ringworm Bush or Senna) was investigated. Multiple shoots were induced from cotyledonary node (CN) explants derived from 15-d-old axenic seedlings on Murashige and Skoog (MS) medium fortified with different concentrations of TDZ. The shoot-forming capacity of CN explants (90% response) was influenced by TDZ concentration (0.5, 1.0, 2.5, 5.0, 7.5, or 10.0 µM). The highest frequency of shoot regeneration (95%), the maximum mean number of shoots per explant (9.2 ± 0.2), and the greatest shoot length (2.6 ± 0.1 cm) were obtained on MS medium fortified with 7.5 µM TDZ after 4 weeks of culture. Prolonged exposure of CN explants to TDZ had an adverse affect on the developing shoots. To avoid this, cultures were transferred to TDZ-free MS medium, or to a medium fortified with various concentrations of 6-benzyladenine (BA) for further multi...

For many applications it is necessary to know the dielectric properties of materials in the microwave range. For the determination of these properties usually a section of a waveguide is homogeneously filled with the unknown material. The permittivity and losses can subsequently be reconstructed from the measured scattering parameters. However, in many circumstances it is not possible to manufacture material samples that perfectly fit into the waveguide. Therefore we have developed a method where the unknown sample is fixed inside the waveguide by a low-loss PTFE holder, e.g., the sample consists of a small circular cylinder and the holder is a block with a corresponding hole. For such a structure the scattering parameters can only be calculated numerically. We use the MAFIA and Microwave Studio FD-TD program packages for this purpose. In order to increase the numerical efficiency of the reconstruction process we compute the broadband scattering parameters over an adequate set of material parameters a priori and then apply an interpolation scheme for the actual determination of the material parameters. The validity of new method has been proven by simulations and measurements.
