Efforts have increased to measure nitrate losses from farmland under different management practices due to environmental and public concerns over levels of nitratenitrogen (NO3-N) in surface and ground waters. This study evaluated the effect of conventional tillage (CT) and strip tillage (ST) practices and three N application rates on NO3-N concentrations in soil water at a 76 cm depth under ir...

The overall aim of this study is to calculate some water properties in the single wall carbon naotubes (SWCNT) and compare them to the bulk water properties to investigate the deviation of water properties inside the SWCNT from those in the bulk. Here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (MD) ...

in this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (swcnt) is reported. methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. some physical properties of the methanol-water mixture such as r...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

Absolute attachment cross sections of single water molecules onto mass-selected protonated water clusters have been measured in the 30-200 size range and for collision energies down to approximately 50 meV. The major surprise is that the attachment cross sections are always smaller or equal to the hard sphere cross section. The attractive interaction between water molecules and charged water na...

Our long-term goal is to develop a suite of compact, inexpensive in situ optical property sensors for use on autonomous platforms. As part of this long-term goal, our Phase I research efforts have focused on design, development, and testing of an inexpensive (nominally expendable) water property measurement system to provide environmental optical parameters in the surfzone that are critical for...
