The presence of water-rich and water-lean nanodomains in a transparent, pressurized "water-acetone-CO2" mixture was revealed by Raman spectroscopy. This nano-structured liquid can be classified as a surfactant-free microemulsion-like system and has the capacity to dissolve hydrophobic compounds, such as ibuprofen, in the presence of large amounts of water. This finding opens new opportunities i...

It is possible to eliminate some of the traditional problems with GIS implementation by changing the model of space used. The Voronoi spatial model has bee used as the basis of a set of core GIS or spatial operations, with encouraging results. It has been implemented in a PC environment so as to leave as much flexibility as possible for the designer of any particular application. Examples inclu...

Various detergents can be used to dissolve phospholipids, resulting in very narrow 31PNMR resonances. The resonances are well resolved, allowing identification and quantitative analysis of phospholipids in a mixture. The chemical shift depends strongly on pH, reflecting changes in the state of ionization of the phospholipid headgroup moieties. Samples of phospholipids dissolved in aqueous deter...

The conventional wisdom suggests that blue-green coalitions can be challenging and often dissolve into class tensions that appear to force unions to choose between job security and environmental health. This digest describes the strategies, such as bridge building and constructing a coalition frame based on the precautionary approach, used by coalition leaders to unite different stakeholders wi...

Most often, our waterways are being polluted by municipal, agricultural and industrial wastes. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria in decomposing the waste, thereby robbing other aquatic organisms of the oxygen they need to live. In this paper, we consider the solution of the optimal control problem for the modified Dissolve Oxygen(DO)/ Biol...

A 68 Ge source can be used to calibrate the positron detection eeciency of a liquid scintillation neutrino detector. A method to dissolve radioactive 68 Ge in pseudocumene-based liquid scintillator is described. The homogeneity of the source distribution has been studied and results for two Ge compounds are discussed. Light yield and light attenuation length of the liquid scintillator are not a...

Crystals retain an imprint of the dynamic changes within a magma reservoir and hence contain invaluable information about evolving conditions inside volcanic plumbing systems. However, instead telling single, simple story, they comprise overprinted evidence numerous processes relating to temperature, pressure composition that drive crystal precipitation dissolution in magmatic To decipher these...

We study the response of a nematic colloidal dispersion of rods to a driven probe particle which is dragged with high speed through the dispersion perpendicular to the nematic director. In front of the dragged particle, clusters of rods are generated which rhythmically grow and dissolve by rotational motion. We find evidence for a mesoscopic cluster-cluster correlation length, independent of th...
