Direct Measurement of the Protein Response to An Electrostatic Perturbation That Mimics the Catalytic Cycle in Ketosteroid Isomerase
hydroperoxide lipids GUV photosensitization methylene blue
2016/5/25
Understanding how electric fields and their fluctuations in the active site of enzymes affect efficient catalysis represents a critical objective of biochemical research. We have directly measured the...
An experimental technique for the direct measurement of N2O5 reactivity on ambient particles
experimental technique direct measurement N2O5 reactivity ambient particles
2010/2/8
An experimental approach for the direct measurement of trace gas reactivity on ambient aerosol particles has been developed. The method utilizes a newly designed entrained aerosol flow reactor coupled...
Direct measurement of evaporation from grassland at Plynlimon
Direct measurement evaporation grassland
2009/6/8
Over the last decade there has been some uncertainty over the calculation of "actual" catchment evaporation from the long-term difference between rainfall and runoff for the grassland Wye catchment at...
Theory and practice of hydrostatic lysimeters for direct measurement of net seepage in a patterned mire in north Scotland
acrotelm blanket mire ecohydrology
2009/3/24
A novel design of lysimeter for use in mires (peatlands) with shallow water tables is described. It employs an hydraulic mechanism for the automatic equilibration of soil moisture distribution between...
Direct measurement of the soil water retention curve using X-ray absorption
X-ray absorption soil hydraulic properties soil water dynamics Richards’equation
2009/3/3
X-ray absorption measurements have been explored as a fast experimental approach to determine soil hydraulic properties and to study rapid dynamic processes. As examples, the pressure-saturation relat...
Direct measurement of particle formation and growth from the oxidation of biogenic emissions
Direct measurement of particle formation oxidation of biogenic emissions
2009/1/15
A new facility has been developed to investigate the formation of new particles from the oxidation of volatile organic compounds emitted from vegetation. The facility consists of a biogenic emissions...
Direct measurement of thed13 C signature of carbon respired by bacteria in lakes: Linkages to potential carbon sources, ecosystem baseline metabolism, andCO2fluxes
the d13 C signature bacteria in lakes potential carbon sources ecosystem baseline metabolism CO2 fluxes
2014/4/18
Using a novel method to measure the isotopic signature (d13C) of respiratory CO2 produced by bacterioplankton, we determined the proportion of terrigenous vs. algal-derived organic carbon (OC) respire...

Direct measurement of diffusivity within diatom aggregates containing transparent exopolymer particles
Direct measurement of diffusivity diatom aggregates transparent exopolymer particles
2014/4/22
We present the first direct measurements of apparent diffusivity within diatom aggregates using a diffusivity microsensor. Transparent exopolymer particles (TEP) and aggregate dry mass (TEP and cells)...
In order to better understand the breakup contribution to fusion, we perfomed light particle coincidence measurements for the systems 6;7Li+12C,59Co at energies near and above the barrier. A three bod...
A Direct Measurement of the Neutron-Neutron Scattering Length
the Neutron-Neutron Scattering Length free neutrons
2010/10/15
A direct measurement of nn-scattering by colliding free neutrons has never been performed. Indirect measurements continue to provide inconsistent results, leaving the issue of charge symmetry in the n...
Magnesium site exchange in forsterite: A direct measurement by high-temperature 25Mg NMR spectroscopy
Magnesium site forsterite measurement high-temperature 25Mg NMR spectroscopy
2012/4/9
High-resolution 25MgNMR data are reported for a single crystal of pure forsterite (Mg2Si04) at temperatures to about 1400°C, which allow rates of exchange ofMgcations among specific sites in the struc...
Direct Measurement of the Relation Between Swelling Pressure and Interlayer Distance in Li-Vermiculite
Double-layer theory Interlayer distance Swelling pressure Vermiculite X-ray diffraction
2012/2/1
To test the double-layer theory of swelling as applied to layer silicates, the interlayer separation, ? in a Li-saturated vermiculite from Grouse Creek, Utah, was measured as a function of the swellin...
