Arsenic content in drinking water and in scalp hair of the arsenic affected areas in Bangladesh were measured using energy dispersive X-ray fluorescence (EDXRF) to determine the contribution of drinking water to body burden and health risks. Around 6

Collapse of non‐isothermal, non‐adiabatic interstellar clouds

Autor: S. P. Tarafdar, Eduard I. Vorobyov

Publikováno v: Astronomical & Astrophysical Transactions. 17:407-431

Using the ZEUS-2D code modified for the purposes of cloud collapse calculations, we explore the dynamics of diffuse interstellar clouds of various masses and initial number densities. We show that heating and cooling processes in interstellar clouds

Hα emission from late type be stars

Autor: Krishna M. V. Apparao, S. P. Tarafdar

Publikováno v: Journal of Astrophysics and Astronomy. 18:145-150

We show here that the Hα flux from late type Be stars can be explained as emission from an HII region formed in the gas envelope around the Be star, by the UV flux emitted by a helium star binary companion. We also discuss the observability of the h

Publikováno v: Biological Trace Element Research. :415-422

A research program related to the assessment of toxic heavy metals and essential trace elements in foodstuffs has been carried out in 12 countries under the auspices of the IAEA. The main purpose of this program was to obtain data on the elemental co

Simultaneous infrared and H-alpha measurements of Be stars

Autor: K. V. K. Iyengar, S. P. Tarafdar, K. K. Ghosh, R. P. Verma, Krishna M. V. Apparao

Publikováno v: Journal of Astrophysics and Astronomy. 14:131-134

The observed infrared excess in Be stars is usually interpreted as free-free and free-bound emission from a hot gas envelope around the Be star. This hot gas should also emit H-alpha line radiation. Earlier observations had suggested that the infrare

The X-ray intensity-hardness ratio relation in LMXRB

Autor: S. P. Tarafdar, Krishna M. V. Apparao

Publikováno v: Journal of Astrophysics and Astronomy. 14:135-139

It is sometimes suggested that the change from the horizontal to the normal branch in the X-ray intensity-hardness ratio diagram of low mass X-ray binaries, is due to a change from a thin to a thick disk. It is shown here that wind from the hot thick

Advancement of Photoionization and Photodissociation Rates Relevant to Astrochemistry

Autor: S P Tarafdar

Publikováno v: Symposium - International Astronomical Union. 150:55-63

The advancement of photoionization and photodissociation rates relevant for interstellar diffuse and dense clouds, circumstellar medium, cometary coma and planetary atmosphere has been reviewed with a mention of uncertainties involved in these rates.
