[1] We use 22 monthly GRACE (Gravity Recovery and Climate Experiment) gravity fields to estimate the linear trend in Greenland ice mass during 2002–2004. We recover a decrease in total ice mass of 82 ± 28 km of ice per year, consistent with estimates from other techniques. Our uncertainty estimate is dominated by the effects of GRACE measurement errors and errors in our post glacial rebound (PG...

Background: This study aimed to investigate the impact of neuromuscular exercises (NE) and local-indigenous games (LIG) on the static and dynamic balance of obese children. Methods: Thirty obese children were randomly assigned to NE (n=15, mean age 10.47 ± 2.1 years, body mass index 29.15 ± 3.01 kg/m2) or LIG (n=15, mean age 10.67 ± 1.52 years, body mass index 29.45 ± 3.41 kg/m2) groups. Both ...

There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...
