To improve the ecologic quality of water bodies, it is essential that tools are available that permit effect assessments for mixtures of chemicals.
When trial data permitted, effects on changes in specific cognitive domains were assessed and effect modification by a variety of factors (eg, age, sex, duration of treatment, smoking, prior stroke or cognitive impairment, folic acid fortification, and baseline plasma concentrations of folate, vitamin B-12, and homocysteine) was also evaluated.
Preliminary models for all outcome measures permitted effect modification by previous level of glycemic control.
A thin metallic film electrode deposited on a porous substrate, in this case a glass frit, in which electrolyte is entrained, may permit electrochemical effects with gas-phase reagents.
These permit the effects of non-uniform proppant concentration across the fracture width to be investigated, under the assumption that the time scale for development of cross slot structure is short compared with that for large scale flow.
A segmental osteotomy model could also permit the effects of naloxone alone and in association with calcium gluconate to be evaluated in a mechanically unstable environment.
They made shirt adornment much easier and permitted new effects, like detailed floral imagery.
(2) Any provision, rule, regulation, ordinance, or permit in effect under any other provision of Federal law.
On the merits, section 404 provides EPA considerable discretion to veto permits whose effects it finds unacceptable.
Filtration data were analyzed using an integrated form of Darcy's law which permits the effects of cell bed hydraulic resistance of pore blockage to be evaluated separately.
