The volume and complexity of these data make the move to electronic capture inescapable, he adds. For many of these techniques, however, the inevitable evolution from paper-based data collection procedures to electronic systems has not been without difficulties. “It may be argued, for example, ...
Approaches that leverage the known equilibrium constant of the creatine kinase reaction, along with HPLC measurement of other phosphagens, may be used to calculate free ADP concentrations in some tissues (73). The rate of ATP turnover (JATP) is another representation of the cell’s energetic ...
In order to properly assess the feasibility of using Laser-Induced Fluorescence (LIF) spectroscopy for soil monitoring, the variation of fluorescence intensity due to the heterogeneity and complexity of soil media was investigated. Different soil mineral
Enzyme inhibition was determined by measuring the absorbance of the p-nitrophenol cleavage product at 405 nm for 35 min with a Multiskan FC microplate photometer controlled by SkanIt ver. 2.5.1 software (Thermo Scientific, Waltham, MA, USA). 3.5. Time-Sliced HPLC Separation Chromatographic ...
2.4. LC-HRMS and NMR Analysis of HPLC Fractions Compound 1 (Figure 7A) showed an [M + H]+ ion with m/z 443.3152, which suggested the molecular formula C28H42O4. The 1H-NMR spectrum showed three aromatic protons of a 1,2,4-trisubstituted benzene [(δ 6.78, d, 8.1 Hz, H-8), (...
[53] have published a study report that contains data on the surface concentrations of acidic and basic groups of asphaltenes from different crude oils. Herein, we exploit the above theoretical developments to study the effect of oilfield brine salinity and pH on the degree of ionization of the...
