The separate standard proposed for soot and air would limit concentrations of particles smaller than 2.5 microns to an average of 15 micrograms per cubic meter measured for three years in a row.
Coprecipitation of Sr with barite could limit concentrations of this element.
In biomass hydrolysis, limiting concentrations of byproducts are important when the hydrolysate is to be used as a fermentation medium.
This latter approach is used in regulatory and industry proposals for limiting concentrations of toxicants such as B[a]P in STPs.
Through a series of experiments carried out using this system, the limiting concentrations of hydrogen in oxygen and helium at different initial pressures and temperatures for the practical operational case were studied, and the influence of ignition energy and initial temperature on the limiting concentration of hydrogen in oxygen and helium was analyzed and discussed.
Limiting concentrations of oxygen, nitrogen, phosphate, and sulphur, or trace element ions like magnesium, calcium, and iron, have been shown to induce synthesis of PHAs (Lee 1996; Kessler and Witholt 2001).
The compounds were added to the cultivation medium at their respective toxicity limit concentrations of 18.0 mM syringic acid, 18.0 mM dihydroferulic acid, 9.0 mM homovanillic acid, 11.0 mM 4 hydroxybenzoic acid, 4.2 mM vanillylidenacetone and 9.4 mM gallic acid.
The trends observed were attributed to the greater ability of lactate oxidisers to scavenge lactate under limiting concentrations of the substrate and their greater resilience to dissolved sulphide species in comparison to lactate fermenters.
This is unlikely to be a function of limiting concentrations of pMHCI complexes on the antigen presenting cells.
The proliferative response of the CTL in response to limiting concentrations of antigen was assessed in 3[H]-thymidine incorporation assays.
Steady state expression of FLO11 was measured at different limiting concentrations of ammonium sulphate, when the cells were precultured in the medium containing excess of ammonium sulphate.
