An appraisal of the equivalence of two media proposed for the isolation of cellulolytic rumen bacteria
… rumen bacteria were investigated. The inorganic medium containing rumen fluid gave greater total counts, greater cellulolytic counts, and a greater variety of morphological forms of cellulolytic rumen bacteria than the rich organic medium containing no rumen fluid. Cellulolytic bacteria …

Inverted micelles: a novel method of theranostic agent encapsulation for enhanced nano-delivery
… that relies on anaerobic reactions in an organic medium. Our encapsulation procedure can also be scaled with high-throughput efficacy. Furthermore, the inverted micelles and NCAP coating consist of materials that have been shown to provide excellent biocompatibility. With this methodology, …

Insights into formation of semiconductor nanocrystals : from first principles calculations to kinetic models of nucleation and growth
… the elementary reaction steps that occur in the organic medium during early stages of particle nucleation. In particular, using density functional theory calculations, we probe the mechanism of formation of active growth species and small molecular clusters. We further explore the effect of …

Industrial applications of flow injection analysis
… oxidation of Fe(II) to Fe(III) by peroxides in organic medium, followed by the colorimetric detection of the latter as the thiocyanate complex. The system exhibits a wide dynamic range and good linearity (e.g., linear r^2, 0.9943 for 0.1 -120 meq/kg cottonseed oil hydroperoxides) with a good …

Effects of nitrogen source and level on the growth and composition of Sinningia speciosa Lodd
… Shoot dry weight of gloxinias grown in an organic medium in the winter was lower with 100% NH₄ than with 100% NO₃ but was unaffected by N level, while in the fall shoot dry weight was lower with 100% NH₄ than with 0 or 50% NH₄, and was reduced at 16 rather than 8 meq N liter⁻¹. In the …

The Incorporation and Controlled Release of Anionic Drugs from a Polypyrrole Membrane Film
… anionic drugs. The drugs, which were small to medium‐large in size, included the aqueous soluble dexamethasone 21‐phosphate disodium (NaDex) and valproic acid sodium (NaVPA) salts, and the less soluble diclofenac sodium (NaDF) salt. Two other drugs, indomethacin sodium (NaIndo) and sulindac …

Spectroelectrochemical, Separation and Surface Functionalisation Studies of Plasmonic Nanoparticles
… a new density gradient system was implemented in organic medium for these water-reactive nanoparticles, and the effects of speed, time, density gradient and initial nanoparticles were explored. Finally, the chemistry of Mg surfaces was studied computationally with density functional theory, …

Studies on lignin biosynthesis and biodegradation
… The effect of horseradish peroxidase/H₂O₂ in organic medium (dioxane/aqueous acetate buffer, pH 5, 95:5) on dehydrogenatively polymerized (DHP) lignin was reinvestigated. We found no evidence for vigorous depolymerization of DHP lignin under these conditions, contrary to claims made by …

Multiphase, Multicomponent Systems: Divalent Ionic Surfactant Phases and Single-Particle Engineering of Protein and Polymer Glasses
… droplet suspended in a second, immiscible liquid medium, and can serve as direct single-particle studies of drug delivery systems that are formed using solvent extraction (e.g., protein encapsulated in a biodegradable polymer), and as model systems with which to study the materials and principles …

Recycling of domestic wastewater treated byvertical-flow wetlands for irrigating crops
… value) was linked to raw wastewater and an organic growth medium, while the plants grown in organic medium and irrigated with outflow from wetlands of large aggregate size, high contact and resting times, diesel-spill contamination and low inflow loading rate produced the best fruits in …
