Comparison of simple potential functions for simulating liquid water

, 1983
Classical Monte Carlo simulations have been carried out for liquid water in the NPT ensemble at 25 °C and 1 atm using six of the simpler intermolecular potential functions for the water dimer: Bernal–Fowler (BF), SPC, ST2, TIPS2, TIP3P, and TIP4P ...

The use of the Normalized Difference Water Index (NDWI) in the delineation of open water features

, 1996
The Normalized Difference Water Index (NDWI) is a new method that has been developed to delineate open water features and enhance their presence in remotely-sensed digital imagery. The NDWI makes use of reflected near-infrared radiation and visible green

THE WATER-WATER CYCLE IN CHLOROPLASTS: Scavenging of Active Oxygens and Dissipation of Excess Photons.

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
Photoreduction of dioxygen in photosystem I (PSI) of chloroplasts generates superoxide radicals as the primary product. In intact chloroplasts, the superoxide and the hydrogen peroxide produced via the disproportionation of superoxide are so rapidly ...

Electromagnetic determination of soil water content: Measurements in coaxial transmission lines

, 1980
The dependence of the dielectric constant, at frequencies between 1 MHz and 1 GHz, on the volumetric water content is determined empirically in the laboratory. The effect of varying the texture, bulk density, temperature, and soluble salt content on this

Organic matter and water‐stable aggregates in soils

, 1982
Summary The water-stability of aggregates in many soils is shown to depend on organic materials. The organic binding agents have been classified into (a) transient, mainly polysaccharides, (b), temporary, roots and fungal hyphae, and (c) persistent ...

Noble metal-free hydrogen evolution catalysts for water splitting.

Chemical Society Reviews, 2015
Sustainable hydrogen production is an essential prerequisite of a future hydrogen economy. Water electrolysis driven by renewable resource-derived electricity and direct solar-to-hydrogen conversion based on photochemical and photoelectrochemical water ...

Water In, Water Out

Scientific American, 2012
Two charts are presented on water consumption, including one showing water use for the top 10 freshwater consumers, including China, India, and the U.S., and one showing the largest net importers and exporters of virtual water, including Great Britain, Germany, and Brazil.

Water, mineral waters and health

Clinical Nutrition, 2006
The authors focus on water resources and the use of mineral waters in human nutrition, especially in the different stages of life, in physical activity and in the presence of some morbid conditions. Mineral water is characterized by its purity at source, its content in minerals, trace elements and other constituents, its conservation and its healing ...
