The TACTIC γ-ray telescope, equipped with a light collector of area ∼9.5m 2 and a medium resolution imaging camera of 349-pixels, has been in operation at Mt.Abu, India since 2001. This paper describes the main features of its various subsystems and its overall performance with regard to (a) tracking accuracy of its 2-axes drive system, (b) spot size of the… (More)
The energy estimation procedures employed by different groups, for determining the energy of the primary γ-ray using a single atmospheric Cherenkov imaging telescope, include methods like polynomial fitting in SIZE and DISTANCE, general least square fitting and look-up table based interpolation. A novel energy reconstruction procedure, based on the… (More)
INTRODUCTION Laparoscopic adrenalectomy has gained favour as a preferred surgical approach in the multiple endocrine neoplasia (MEN) type 2 patients. Currently, there is limited literature on bilateral simultaneous laparoscopic adrenalectomy in MEN 2 syndrome. We reported two cases of bilateral pheochromocytoma associated with MEN 2 syndrome cured by… (More)
Background: Human papilloma virus is a dominant factor for cervical carcinogenesis. About 70% of cervical cancer cases are related to infection with high risk (H-R) HPV types mostly HPV16 &HPV18. First coitus at a younger (≤ 15) age, high parity, and early age at marriage behave as major risk factors for HPV infection.
The BL Lac object H1426+428 (z ≡ 0.129) is an established source of TeV γ-rays and detections of these photons from this object also have important implications for estimating the Extragalactic Background Light (EBL) in addition to the understanding of the particle acceleration and γ-ray production mechanisms in the AGN jets. We have observed this source… (More)
