Use of hydrothermal methods for the synthesis of metal molybdates, copper carboxylates and molybdenum phosphates
(1990)
In this work, hydrothermal reactions were studied as a synthetic method in three systems: metal molybdates, copper carboxylates and molybdenum phosphates. Different solvents were used in each system studied to determine ...
Fate of (14C)xanthotoxin (8-methoxypsoralen) in laying hens and lactating goats
(1990)
The metabolism of xanthotoxin, a naturally-occurring furanocoumarin photosensitizer, was studied in laying hens and lactating goats treated with a single oral dose equivalent to 10 mg xanthotoxin/kg of body weight. Within ...
The chemical generation of superoxide ion, and its relative reactivity (versus hydroperoxide ion and hydroxide ion) with halocarbons, esters, and nitriles in aprotic media
(1990)
With dioxygen-saturated (1 atm, 2.1 mM) dimethyl sulfoxide solutions that contain aniline (1-15 mM), the addition of excess hydroxide ion (10:1 HO-/PhNH2) yields approximately two superoxide ions (O2-), one azobenzene, and ...
High mass diffractive dissociation at 27.5 GeV proton-proton interactions in exclusive final states
(1990)
A study of diffractive production in 27.5GeV/c proton-proton interactions is presented. The detector that was used to take the data and the techniques that were used to analyze the data are also discussed. The results are ...
Selection for summer stress resistance in creeping bentgrass
(1990)
Morphological and physiological evaluations were made of creeping bentgrass (Agrostis stolonifera subsp. palustris (Huds.) plants which survived supraoptimal soil temperature stress. Those plants that survived possessed a ...
Identification of linking and boundary spanning activities of continuing education program developers in public community colleges in Texas
(1990)
Continuing education (CE) departments operate within, yet at the periphery of, academic institutions. Their survival is dependent upon identifying and responding to environmental changes, linking with client groups that ...
Supercritical extraction of polychlorinated biphenyls from a solid matrix
(1990)
The contaminated soil around the uncontrolled waste sites in the United States is considered to be a potentially hazardous environmental pollution. At present, over 1,000 waste sites are on the National Priorities List ...
Purification of bacterial luciferase native subunits and investigation of their folding, association and activity
(1990)
Bacterial luciferase from Vibrio harveyi is a heterodimeric enzyme comprised of two homologous subunits, α and β, encoded by adjacent genes, luxA and luxB. The level of accumulation of active enzyme was similar when the ...
Cinematic aspects and film adaptations of selected works of Thomas Hardy
(1990)
Thomas Hardy's works are eminently adaptable to film because they are dramatic in nature and cinematic in technique. His love for the theatre is reflected in his plots involving "actors," his view of life as a theatrum ...
Development of an accurate and practical equation of state based on perturbation theory and random-closest-packed born spheres
(1990)
Equation of state calculations are used by engineers in all phases of chemical process design and control. New processes often are designed to operate under conditions for which insufficient experimental data exist, and ...
