https://www.google.com/: THE40Ar technique has been used to unscramble mixtures of radiogenic, parentless (excess) and atmospheric argon components in (hydrothermal) fluid inclusions through correlations with K, Cl and 36Ar respectively1. These procedures are also applicable to mantle derived argon isotopes in diamond2, previously reported as having anomalously high (6 Gyr) K Ar ages3. Here we describe 40Ar measurements on coats and cores of 'coated stones' similar to those analysed for trace elements by Navon et al.4, and on fluid inclusions in olivine from an East African mantle xenolith with mid ocean ridge basalt (MORB) affinities5.

https://www.youtube.com/: MONTREAL It is a rite of spring. For 25 years, the Fondation de la mode de Montral has been holding a fundraising gala/fashion show, and handing out approximately $100,000 in scholarships to promising fashion design students. This year 10 students received grants of $3,000 to $15,000, taking them to schools like the prestigious Central Saint Martins College of Art in London ($15,000 each to Alexandre Arsenault and Christine Charlebois) and the Fashion Institute of Technology in New York ($15,000 to Marc Antoine Fortin) or in the case of twins Frdric and Mathieu Joncas ($3,000 each), keeping them right here at the cole suprieure de mode de Montral.The twins have been front and centre at fashion events this season, having also won first and second prizes at the Tlio student competition.
