Removal of organic contaminants from groundwater by reverse osmosis
… and to correlate membrane performance with physical/chemical properties of the solute contaminants. Aromatic contaminants were removed to concentrations below the current MCLs. However, volatile contaminants were not sufficiently rejected by the membrane to meet either the MCL for total …

The removal of pesticides and heavy metals by reverse osmosis
… on the characteristics of the membrane and the physical/chemical properties of the pesticides. Pesticides in the mixed solution were found to behave independently. Sorption of the pesticides onto the reverse osmosis membrane was found to play a major role in the overall removal efficiency. …

Structure-function photodynamic herbicidal studies of phenanthroline, dipyridyl and pyridine analogs
Physical-chemical properties of photodynamic modulators were studied in johnsongrass seedlings and their structure-function relationships were analyzed. The results showed that all three groups of modulators induced DV-MPE formation. DV-Pchlide formation was induced by phenanthroline and dipyridyl …

Large Margin Random Forests On Mixed Type Data
… by features such as sequence length and physical-chemical properties. They can also be represented by pairwise similarities, gene expression levels, and phylogenetics position. Hence, the types vary from numerical features to categorical features. An efficient way of learning from …

New immobilized antimicrobial polyethylenimines : synthesis and properties
… activity relationships. Various physical-chemical properties of each surface were correlated with their virucidal activities to identify key antiviral surface properties. The accessibility of N-alkyl-PEI quaternary ammonium groups to influenza virus was subsequently identified as …

Boron metasomatism in the Alta stock contact aureole, Utah
… aureole, Utah, were studied by evaluating chemical additions and depletions in igneous, replacement skarn, and carbonate whole-rock samples. Of the major and trace elements studied, boron proved to be the most interesting tracer of fluid, due in part to extensive borate mineralization …

Fragments of the human antimicrobial LL-37 and their interaction with model membranes
… antibiotics. The aim of this work was the physical-chemical characterization of two fragments of LL-37, a human antimicrobial peptide from the cathelicidin family. The fragments LL-32 and LL-20 exhibited contrary behavior in biological experiments concerning their activity against bacterial …

Variations in the biodegradation potential of toluene with increasing depth in an unsaturated subsurface environment
… these groups were determined at each soil depth. Physical and chemical parameters of the subsurface environments were also investigated to observe their impact on microbial biodegradation potentials. These included changes in soil particle size, moisture content, and pH with increasing depth. …

PCP and conformational motifs: applications in predicting mechanical strength, allergenicity of proteins and vaccine design
The functions and properties of proteins are mainly determined by their amino acid sequences and 3-dimensional structures. Motifs composed of amino acids that are either continuous in sequence or cluster in space play important roles in structures and functions of proteins. The functional …

Multiscale Simulations of Phosphatidylinositol Bisphosphate: Understanding Its Biological Role Through Physical Chemistry
… and PtdIns(4,5)P2 - act by changing the physical-chemical properties of the membrane rather than by specific biochemical binding to proteins. We also predict that PtdIns(3,5)P2 and PtdIns(4,5)P2 alter the mechanical of properties in distinct ways due to the larger size and altered charge …

A study of mechanochemical activation in solid-state synthesis of advanced ceramic composites
Mechanical methods of the activation of chemical processes are currently widely used for the synthesis of various compounds. Intensive (dry) milling of ultra-fine and nanometer-sized powders is considered to be a way of applying “mechanochemical activation” that involves dispersion of solids, …

Connecting models and observations of disc evolution and planet formation
Planets are assembled in and inherit their properties and composition from gas- and dust-rich discs orbiting young stars. Over the last decade, the Atacama Large Millimeter/submillimeter Array revolutionised our understanding of planet formation, opening up the possibility of determining the …
