(A) Determination of ATP hydrolysis activity of ZIKV helicase.
Radon emanation is a well-known source of uncertainty at determination of activity concentration index for building materials and NORM.
This necessitates a frequent recalibration of the remaining dose (determination of activity per unit volume) and careful planning with respect to patient scheduling.
A method based on liquid liquid equilibrium is proposed for the determination of activity coefficients.
As pointed out by Wang et al. [2], there are difficulties in determination of activity coefficients of reaction species in a constant ionic medium.
The advantages of PET include its inherently quantitative nature, enabling the absolute determination of activity per unit volume of tissue with and a higher resolution than SPECT reconstructions of 99mTc-diphosphonate uptake.
1) Determination of Activity Level and Clothing Insulation.
PET is the most accurate imaging method for the determination of activity concentrations in vivo.
Reactions were conducted based on the determination of activity method using 0.05 0.5 mM ABTS.
Biological evaluation included determination of activity against chloroquine-sensitive and chloroquine-resistant Plasmodium falciparum strains.
