Concentration of 1-methylnaphthalene (1-MN) (M [+ or -] SD) in rat (N = 4 per group) blood during repeated inhalation exposure (5 days, 6 h/day) to 1-MN vapor at target concentration of 50 mg/[m.sup.3] and 200 mg/[m.sup.3]
The effect of dengue virus DNA target concentration was further explored by studying the changes in absorbance intensity at wavelength of 520 nm.
Results were proportional to the target concentration (0.8 [greater than or equal to] a [greater than or equal to] 1.2) and had a good correlation coefficient ([R.sup.2] [greater than or equal to] 0.9) between the two sets of data demonstrated with all tested strains, except for Aspergillus brasiliensis (Figure 1).
Despite the increase in dose, the blood concentration of FK506 was only maintained at a lower level, failing to achieve the target concentration most of the time.
This could be explained by the fact that these recalcitrant hydrocarbons were present in very high initial concentrations (approximately 500 mg/kg as target concentration with variation less than 10%) mimicking industrially contaminated sites and thus maximum 6 h of irradiation did not result in a significant formation of oxidative species (hydrogen peroxide and hydroxyl radicals) that were responsible for the POPs degradation.
The test animals were exposed to 17.8[cm.sup.3]h-1[m.sup.-3] (target concentration) of wholly vaporized PMS blend UG for 6 hr/day, 5days/week, for 10 weeks.
While a lot can be done with technologies that are currently available, the reality is that meeting even a 450-part-per-million target concentration for carbon dioxide would be difficult to achieve without new technologies, particularly carbon capture and sequestration.
Real-time sampling collects information about mass, particle number, and particle size during exposure, so exposures can be adjusted to correct the dose as needed to match a target concentration. Post-exposure analyses of collected samples verify the correct dose, by determining the mass gravimetrically and providing necessary information on other characteristics of the particle, the size during and after exposure, and the chemical composition, shape, and surface chemistry.
Whereas standard PCR methods analyze product formation during the plateau phase (or endpoint), real-time PCR quantification occurs during logarithmic amplification of the target, which can be more accurately related to initial target concentration. This difference is critical for the development of assays comparable to the RFTM method, which provides not only presence/absence of the parasite but also infection intensity.
FT4SS is a 0.01 N sodium hydroxide (NaOH) solution of T4 at a target concentration of 50 [micro]g/mL.
That is, in the initial testing of samples, we estimate the number of 2-h vacuumings of the room's surfaces and contents that are required to achieve the target concentration [[bar.c].sub.f].
It is obvious that water treatment plant operators in Ohio are knowledgeable about the target concentration of public water supplies.
