Colonel Henchal said ricin is an effective agent against individual targets but would be less effective in a major attack because large quantities of the agent would be required.
Using themogravimetric analysis, the optimal quantity of the silylant agent to neutralize the superficial silanols was evaluated.
Manipulations in the properties and quantity of the wetting agent easily achieved by modifying process trajectories in the solvent space lead to significant variations in agglomerative particle shapes.
The homeopathic practitioner creates his healing potions by starting with a minute quantity of the curative agent (some natural herb, mineral or whatever), diluting it in water by one part in 10, shaking the flask and then repeating the process again and again.
This is then compared with the time-density curve of the tissue being analysed in order to distinguish between the quantity of contrast agent within the blood vessels (vascular compartment) and the quantity present in the interstitium (extra vascular/extra cellular compartment) [ 23].
Among the procedural data, only duration of the procedure (shorter in the direct stenting group), the number of balloons used, and the quantity of contrast agent (lower in the direct stenting group) were significantly different between the 2 groups (P <.05).
Syria is widely believed to possess large quantities of the blister agent sulphur mustard.
In the case of ammonium sulphate, precipitation was optimized by addition of variable quantities of the precipitant agent until enzymatic activity recovered in the supernatant (measured in triolein hydrolysis) was minimal.
Even small molar quantities of the imaging agent may saturate the receptor and limit the ability to visualize receptor expression [ 86, 87].
To examine the effect of the quantity of nucleating agent, we chose one crystallization condition (lysozyme/dried seaweed, condition D3: 0.1 M Hepes (pH 7.5), 2% PEG 400, 2 M ammonium sulfate) and set up drops with diminishing amounts of nucleant (6 replicate drops for each amount of nucleant).
