Strontium concentration and isotopic data for subsurface flowing groundwaters of the Ganges-Brahmaputra (G-B) delta in the Bengal Basin demonstrate that this is a potentially significant source of strontium to the oceans, equal in magnitude to the dissolved strontium concentration carried to the oceans by the G-B river waters. The strontium concentrations of groundwaters are higher by a factor ...

Surface modification techniques have been applied to generate titanium implant surfaces that promote osseointegration for use in dental applications. In this study, strontium-doped brushite coatings were deposited on titanium by electrochemical deposition. The phase composition of the coating was investigated by energy dispersive X-ray spectroscopy and X-ray diffraction. The surface morphologie...

Precision timekeeping has been a driving force in innovation, from defining agricultural seasons to atomic clocks enabling satellite navigation, broadband communication and high-speed trading. We are on the verge of a revolution in atomic timekeeping, where optical clocks promise an over thousand-fold improvement in stability and accuracy. However, complex setups and sensitivity to thermal radi...

Strontium ranelate is used for treatment of osteoporosis. The present work deals with method development for estimation of Strontium ranelate in bulk dosage form by UV spectrophotometry. A new simple, accurate and sensitive method for estimation of Strontium ranelate from bulk dosage form has been developed. The method employs zero order derivative spectroscopy. Estimation of Strontium ranelate...

The Charpy impact energy of A356 alloys has been measured. Instrumented Charpy impact tests have been conducted at 25, 100, 150, and 200 ~ The Charpy specimens were machined from plate castings or tapered cylindrical castings. The plates were produced in sand molds, and tapered cylinders were produced in water-cooled copper molds. Both unmodified and strontium-modified castings were tested. The...

Abundance ratios relative to iron for carbon, nitrogen, strontium and barium are presented for a metal-rich main sequence star ([Fe/H]=–0.74) in the globular cluster ω Centauri. This star, designated 2015448, shows depleted carbon and solar nitrogen, but more interestingly, shows an enhanced abundance ratio of strontium [Sr/Fe]≈1.6 dex, while the barium abundance ratio is [Ba/Fe]≤0.6 dex. At th...
