Critical Appraisal of Parasitological Disorders in Ayurveda with Special Reference to Krimi Roga
Abstract: Description of parasitological disorders in Ayurveda is in a haphazard shape and it is described in various chapters in a scattered form. Significant contribution for the understanding of parasitological diseases has been made by Ayurvedic Acharyas. Since the Vedic period, the Indian physicians have been well aware of the presence of micro-organisms. They described the etiological factors very vividly but nowhere they have mentioned the parasites responsible for the manifestation …

A Compact CPW-fed Quadruple-band-notched Antenna with Concentric Annular-rings for UWB Applications
Abstract: In this paper, a compact coplanar waveguide (CPW)-fed quadruple-band-notched antenna with concentric annular-rings for ultra-wideband (UWB) applications is presented. The proposed antenna consists of four concentric annular-ring resonators, a circular shape radiating element and a CPW feed line. The quadruple band rejection is easily achieved by controlling the widths and radii of four concentric annular-ring resonators. Through the exception of four stop-bands at 3.29 to 3.7 GHz, 5.07 to 5.92 …
