Clays for cool clotting

On Clays

Base-exchange determinations were made on selected clays of the montmorill0niteillite group to test this method as an analytical tool for the analysis of mixed-layer aggregates. The relatively rapid manganese method developed by Bower and Truog was used and its precision determined oll monodisperse, monomineralic fractions and monodisperse fractions of prepared mixtures of illite and montmorill...

Calcium for strong clotting

alcium fluctuations in the bottom layer of a platelet mass are propagated upwards to determine the size of a blood clot, or thrombus, according to results from Nesbitt et al. presented on page 1151. Platelets adhere to substrates in the vessel wall through receptors such as GPIb and certain integrins. Initial receptor engagement stimulates Ca 2 ϩ spikes in the platelets that lead to firm, perma...

'Cool', Brands and 'Cool' Brands

The term ‘cool’ is widely used expression in popular culture. This word is prefixed liberally with anything including people, behavior, place and brands. Notwithstanding ambiguity about what it stands there is complete clarity that it certainly adds value. ‘Cool’ in this perspective is precious resource which can be used in brand building. The authors’ exploration into its genesis and meaning r...

ESR of clays

Electron spin resonance (ESR) spectroscopy has contributed significantly to the identification and characterization pf paramagnetic impurities associated with clays, Following a brief discussion of the general principles of the technique, a review is given of the application of ESR to the study of those paramagnetic species (chiefly iron and radiation-induced lattice defects) located either wit...
