AIMS Aqueous flare was used to determine the frequency and amount of blood-aqueous barrier breakdown and correlate it with tumour variables. METHODS Aqueous flare was analysed prospectively by laser flare photometry in 139 consecutive patients seen in the oncology unit for choroidal melanoma. Both eyes of patients were examined with a laser flare cell meter in a standard fashion. RESULTS Me...

Remediation processes for recovery and reuse of chromated-copper-arsenate- (CCA) treated wood are not gaining wide acceptance because they are more expensive than landfill disposal. One reason is the high cost of the nutrient medium used to culture the metal-tolerant bacterium, Bacillus licheniformis, which removes 70-100% of the copper, chromium, and arsenic from CCA-treated southern yellow pi...

This experimental study was focused on the study of assimilatory pigments and nucleic acid levels in young plants intended for agricultural use (Zea mays) in presence of water based magnetic fluid in culture medium. The water based magnetic fluid was constituted by coating the small magnetic nanoparticles with perchloric acid and further dispersion in water. Saturation magnetization of our magn...

Aqueous polymer quenchants are being used increasingly in steel heat treatment industries as a substitution for conventional quenchants. By adjusting the quench parameters of the polymeric media, it is possible to achieve desirable microstructure and mechanical properties in addition to reduction in distortion and cracking. In this work, Polyalkylene Glycol (PAG) aqueous solution was used as th...

An unprecedented C-3-alkylation reaction of indoles with terminal alkynes in aqueous medium has been developed using catalytic amounts of ruthenium and trifluoroacetic acid.

An extremely strong oxidant, ferrate (Fe(VI) or FeO4(2-), has been produced electrochemically in an acidic aqueous medium for the first time.
