Feasibility of de-lithiation of more than one Li+ ion per formula unit of Li2FeSiO4 of Pmn21 polymorphic phase without and with Ti modification is estimated using FPLAPW approach.
Then fitness of the two solutions (before and after modification) is estimated.
The degree of modification was estimated by UV absorbance of the HQ-PAA using a calibration curve that was established by measuring the absorbance of dilute hydroquinone solutions at λ max = 288 nm; as can be noticed in the figure, the variations of modification degree increased with increasing [BQ]/[AA] and high substitution extents (29 32 %) were gained with a ratio higher than 1.
The fatty amine modification of dextran was confirmed by 1H NMR spectroscopy (Varian 500MHz NMR spectrometer, Varian Inc ,CA) and the % lipid modification was estimated to be 7 mole% (Fig. 1).
The stearyl modification of dextran was confirmed by NMR spectroscopy and the % lipid modification was estimated to be 3-7 mole%.
The degree of modification was estimated by the trinitrobenzensulphonic acid method of Fields [ 37].
Considering limiting cases (see the Supporting Information), the effect of microenvironmental exposure modification is estimated to account for <30% absolute uncertainty, roughly consistent with estimates elsewhere.
Using ten years of mid-block crash data on urban arterials and collectors from four cities in Nebraska, crash modification factors (CMFs) were estimated for various lane widths and crash types.
The modifications up to 1993 were estimated to have added £24m to the cost; the most recent modifications, another £92m, making £116m altogether, or £350 per gun, to put right all the things that were wrong when production began.
In this study, rotor misalignments of a target machine were estimated and helix modifications which absorb the bad influence of these misalignments were designed by using transmission error simulation.
It should be emphasized that the free parameters were estimated by minimal modifications to basal values.
