The intrapleural pressures on the contralateral side in pleurisy with effusion were within the normal range, the normal intrapleural pressures among Indians being ?14 to ?3 cm. of water during inspiration, ?10 to 0 cm. water during expiration, and the mean pressure ?12 to ?2 cm. water (Laha, 1946). Neither the amount nor the duration of effusion had any effect on the intrapleural pressures on t...

Water and hydrogen at high pressure make up a substantial fraction of the interiors of giant planets. Using ab initio random structure search methods we investigate the ground-state crystal structures of water, hydrogen, and hydrogen-oxygen compounds. We find that, at pressures beyond 14 Mbar, excess hydrogen is incorporated into the ice phase to form a novel structure with H4O stoichiometry. W...

Using deuterium oxide dilution technique, the total body water changes of five infants maintained on total parenteral nutrition have been determined. While average weight gains of from 14 to 53 g/day were documented, there were decreases in percentage total body water from 13 to 50%. These data taken together support tissue accretion rather than water retention as the mechanism of weight gain i...

Phytolith remains of rice (Oryza sativa L.) recovered from the Shangshan site in the Lower Yangtze of China have previously been recognized as the earliest examples of rice cultivation. However, because of the poor preservation of macroplant fossils, many radiocarbon dates were derived from undifferentiated organic materials in pottery sherds. These materials remain a source of debate because o...

Very soon after the discovery of radioactivity, measurements of the heavy radioactive elements existing in nature were undertaken to determine the age of rocks (Rutherford 1904), but only when Professor Willard Libby in an evening lecture during the first United Nations Conference on the Peaceful Uses of Atomic Energy in Geneva in 1955 described how he and his research team had evolved the carb...
