Ethnobotanical Survey of Sariska and Siliserh Regions from Alwar District of Rajasthan, India

The aim of present survey is to identify and document the plants used amongst the indigenes of Sariska and Siliserh regions of Alwar district from Rajasthan, India. A total of 110 species of plants representing 88 genera and 43 families employed in the literature as traditional medical practice have been recorded from the studied regions. Ailments such as fever, diorrhoea, dysentery, skin-problems, jaundice, rheumatism etc. are mostly treated with the different medicinal plants. Due to overgrazing, encroachments, unsustainable utilization and other developmental activities in the regions, several persistent medicinal plant species are on the verge of extinction. Due to lack of awareness and research on these groups of plant in this area, people of this region are unaware of the wealth of this heritage. The survey provides a veritable source of information for traditional medical practitioners and medicinal plant researchers and help in developing strategies for future conservation

Amplitude modulation of solar p-modes by surface magnetic fields

Context.It is known from Doppler velocity measurements that the amplitudes of solar p-modes are modulated by strong photospheric magnetic field. Aims.The aim of this paper is to investigate amplitude modulation by model surface magnetic fields. Methods.Linearised magnetohydrodynamics equations, in the absence of gravity, are used to derive the inhomogeneous wave equation which is then solved using the Born Approximation. Results.The amount of modulation depends on the plasma beta, the distance from the magnetic region and the wavenumber. It is also found that the direction of observation could also have an effect on the amount of modulation. Finally, the applicability of the findings to the observational data suggests that the modulation depends on the properties of the magnetic field region and measuring it is an un-contaminating probe for the magnetic field
