Several researchers have shown that Pt-Rh bimetallic catalysts can perform synergistically for the NO/H2, NO/CO, CO/O2, and NO/CO/HC reactions [1-5]. Lakis and coworkers clarified some of the mystery surrounding the synergistic performance of Pt-Rh catalysts for the NO + H2 reaction by using analytical electron microscopy (AEM) to show that the synergistic performance of a Pt(95%)Rh(5%)/γ-Al2O3...

mixed infection of plants with more than one virus results in different types of interactions. interaction between two recently identified lettuce infecting viruses in iran, lettuce x potexvirus (levx) and rubus chlorotic mottle sobemovirus (rucmv), was studied on co-infected chenopodium murale and chenopodium quinoa plants. plants were mechanically inoculated with either levx, rucmv or both. c...

objective(s): to evaluate the in vitro interaction between different extracts of thymbra spicata l. and certain antimicrobial drugs of different mechanisms, including ampicillin, cefotaxime, amikacin and ciprofloxacin. this study was performed against multidrug-resistant strains of staphylococcus aureus and klebsiella pneumoniae. materials and methods: evaluation of antibacterial activity and s...

conclusions based on the results of the current study, it was concluded that aloe vera, licorice and mint extracts had synergistic effects on the viability of dermal fibroblasts; in addition, the combination of aloe vera and licorice with either henna or myrtle, and aloe vera and mint with either cedar or ginger resulted in synergistic effects on viability of dermal fibroblasts. the third categ...

laboratory-scale experiments were conducted to evaluate the joint action toxicity and biochemicaleffects of sublethal concentrations of forcados light crude oil (flco) and three dispersants against clariasgariepinus over a period of 28 days. the derived 96hrlc50 values revealed that the dispersant, ds/tt/066(0.03ml/l) was the most toxic, followed by dispersant, oc/tt/osi (0.19ml/l), flco (5.06m...
