The aim of this study was to derive a methodology for calculating sequential water balance that accurately estimates the occurrence excess in soybeans cultivated lowlands. We tested four calculation strategies associated with simulation soybean development, which differed on rainfall and time drainage from soil macropores. Data volumetric moisture monitored three layers throughout cycle 2014/15...

Stable isotopes of water have long been used to improve understanding of the hydrological cycle, catchment hydrology, and polar climate. Recently, there has been increasing interest in measurement and use of the lessabundant O isotope in addition to H and O. Off-axis integrated cavity output spectroscopy (OA-ICOS) is demonstrated for accurate and precise measurements δO, δO, and O-excess in liq...

A cross-sectional survey of 102 Peace Corps volunteers in Niger, West Africa, in 1998 had previously demonstrated a high rate of thyroid dysfunction and goiter attributable to excess iodine from their water filters. The Peace Corps volunteers were followed-up a mean of 30 wk after they ceased using iodine-based water filtration systems. Goiter was present in 44% of subjects during excess iodine...

Earthquake-induced increases in streamflow, producing ;0.7 km3 of total excess water, were documented after the 1999 (Mw 5 7.5) Chi-Chi earthquake in central Taiwan. Analysis of stream gauge data and well records suggests that the excess water originated in the mountains. We propose that the extensive high-angle fractures formed during the earthquake allow rapid release of water from mountains ...

The heat balance under electrolysis in 1M Li2SO4 light water solutions was measured using Pd rods or Pd coated Ni (Pd/Ni) rods for cathode. We detected large excess heat of more than 10% in 6 of 28 experiments. However, in many other experiments, no excess or only small excess heat was observed. In most cases the excess heat was 5% or less. In order to confirm the excess heat, we have to find t...

The IXth and the Xth cranial nerves in Anguilla anguilla were transected, and the effects upon ion and water balance were studied in fresh water and sea water, and during transfer from fresh water and vice versa. In fresh water there is a slow demineralization due to an excess loss of Na and Cl ions. During freshwater to seawater transfer the eel survives only for 4-5 days. The fish do not drin...
