I) UVAL’S EXAMINATION by thermal gravimetry of nearly 1000 chemical precipitates (1) had suggested to one of us the employment of thermal methods in the analysis of concretions of biologic origin. Indeed, use of the thermogravimetric technic was made in conjunction with infrared spectrophotometry (2) and X-ray crystallography (3) in investigations concerning tile formation mechanism of renal tr...

Delay of the Global Positioning System (GPS) signal due to atmospheric water vapor is a major source of error in GPS surveying. Improved vertical accuracy is important for sea level and polar isostasy measurements, geodesy, normal fault motion, subsidence, earthquake studies, air and ground-based gravimetry, ice dynamics, and volcanology. We conducted a GPS survey using water vapor radiometers ...

A new class of microporous adsorbents, the metal-organic frameworks was recently developed. Despite their promising characteristics, not much is known about their adsorption behaviour, certainly for mixtures. In this work, vapour and gas phase adsorption and separation of (i) linear and branched alkanes, cyclohexane and benzene, (ii) C8 alkylaromatic compounds and (iii) CO2 and CH4 is studied o...

The poorly known correction for the ongoing deformation of the solid Earth caused by glacial isostatic adjustment (GIA) is a major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry and to a lesser extent satellite altimetry. In the past decade, much progress has been made in consistently modeling ice sheet and solid Earth interactio...

The work is devoted to the study of physicochemical and surface-active properties N-(benzoyl)-N'-(phenylsulfonyl)hydrazine (BPSH) assess possibility using reagent in processes concentration non-ferrous metal ions. solubility ethanol, 0.1 mol/l KOH solution, toluene, chloroform, hexane was studied by spectrophotometry, refractometry, gravimetry. Acid-base equilibria solutions hydrolytic stabilit...
