Computer Aided Design (CAD) of a Multi-component Condenser (2007)
Bandyopadhyay, S., Alam, M.S., Agrawal, V.K., Wasewar, K.L.
In the case of multi-component condensation the ‘condensing vapour contains a mixture of components having different boiling points, which condense over a wide temperature range, either in presence...
The dependence of the estimated luminosities of ULX on spectral models (2007)
Devi, A. Senorita, Misra, R., Agrawal, V. K., Singh, K. Y.
Data from {\it Chandra} observations of thirty nearby galaxies were analyzed and 365 X-ray point sources were chosen whose spectra were not contaminated by excessive diffuse emission and not affected...
Anti-correlated hard X-ray time lags in Galactic black hole sources (2007)
Sriram, K., Agrawal, V. K., Pendharkar, Jayant K., Rao, A. R.
We investigate the accretion disk geometry in Galactic black hole sources by measuring the time delay between soft and hard X-ray emissions. Similar to the recent discoveries of anti-correlated hard...
The Unusual Spectrum of the Ultra Luminous X-ray Source, M82 X-1 (2006)
The results of a spectral analysis, using {\it XMM-Newton} and {\it Chandra} data of the brightest ultra luminous X-ray source in the nearby galaxy M82, are presented. The spectrum of M82 X-1, was...
Anti-correlated hard X-ray time lag in GRS 1915+105: evidence for a truncated accretion disc (2005)
Choudhury, Manojendu, Rao, A. R., Dasgupta, Surajit, Pendharkar, J., Sriram, K., Agrawal, V. K.
Multi-wavelength observations of Galactic black hole candidate sources indicate a close connection between the accretion disk emission and the jet emission. The recent discovery of an anti-correlated...
Dasgupta, Surajit, Rao, A. R., Dewangan, G. C., Agrawal, V. K.
We present the results of an analysis of data from XMM-Newton and CHANDRA observations of the high luminosity narrow-line quasar PG 1404+226. We confirm a strong soft X-ray excess in the X-ray...
X-ray spectral evolution of low-mass X-ray binary GX 349+2 (2003)
We present the results of a systematic investigation of spectral evolution in the Z source GX 349+2, using data obtained during 1998 with Proportional-Counter-Array (PCA) on-board the RXTE satellite....
Residual radioactivity of silicon doped by transmutation (1979)
The complex nuclear reaction (Si-30 → Si-31 → P-31 → P-32) leading to the formation of radioactive P-32 by irradiation of silicon with thermal neutrons, has been studied. An...

The distribution of phosphorus and gold in neutron irradiated silicon (1978)
The uniformity of phosphorus concentration produced by nuclear transmutation and the distribution of other elements such as gold have been studied to observe the possible influence of the neutron...
