Diffusion of Heavy Water into Ordinary Water

Turning wine into water: Can ordinary speech be artificially nasalized?

Synthetic speech has recently been used to study resonance and voice disorders. The advantage of synthetic speech is that it becomes possible to control and artificially manipulate acoustic variables related to a specific perceptual feature without confounding effects from other co-occurring problems often found in disordered speech. To date, synthesis has been restricted to vowels in isolation...

Discovery of Interstellar Heavy Water

We report the discovery of doubly deuterated water (D2O, heavy water) in the interstellar medium. Using the James Clerk Maxwell Telescope and the Caltech Submillimeter Observatory 10 m telescope, we detected the 110–101 transition of para-D2O at 316.7998 GHz in both absorption and emission toward the protostellar binary system IRAS 16293 2422. Assuming that the D2O exists primarily in the warm ...

Removal of Heavy Metals from Waste Water Using Water Hyacinth

-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...
