On the decrease of sunspot activity and absence of severe space weather conditions during the multiple planetary conjunction periods of 1850-2000 AD
N. G. Nisha, T. E. Girish
We have studied solar activity and space weather conditions during multiple planetary conjunction periods ( MPC) as observed from Earth during the years 1850-2000 AD. Significant d…
X-ray Reflectivity measurements of Speculum metal mirrors using Synchrotron radiation
E. A Nazimudeen, T. E Girish, Sunila Abraham +5
Recent advances in grazing incidence X-ray optics using synchrotron radiation sources have stimulated the need for basic research in high quality mirror materials for novel applica…
Parity of the Solar Magnetic Fields and Related Astrophysical Phenomena
G. Gopkumar, T. E. Girish
The cumulative contribution of odd (Bo) and even (BE) parity zonal magnetic multipoles to the solar magnetic fields is calculated using spherical harmonic coefficients of the photo…
A possible relationship between Global Warming and Lightning Activity in India during the period 1998-2009
Felix Pereira B., Priyadarsini G., T. E. Girish
Lightning activity on a global scale has been studied season wise using satellite data for the period from 1998 to 2009. Lightning activity shows an increasing trend during the per…
On the Electrical and Magnetic Properties of some Indian Spices
Samson. K. Baby, T. E. Girish
We have made experimental measurements of electrical conductivity, pH and relative magnetic susceptibility of the aqueous solutions of 24 indian spices. The measured values of elec…
Photovoltaic Power Generation in the Stellar Environments
T. E. Girish, S. Aranya
In this paper we have studied the problem of photovoltaic power generation near selected stars in the solar neighborhood. The nature of the optical radiation from a star will depen…
