GFR was calculated from serum creatinine using the simplified equation from the Modification of Diet in Renal Disease Study Group (11).
Advanced renal disease was defined as an estimated glomerular filtration rate less than 30 ml/min/1.73 m2 at ICU admission (calculated using the simplified equation derived from the 'Modification of Diet in Renal Disease'(MDRD) study) [ 14].
The ILS data analysis method uses the simplified equation of Hellström, Eskilson, and Mogensen (Eskilson 1987) to model temperature results of TRT, which turns into a line in the dimension of the time logarithm (Equation 1): {T}_{mathrm{f}}(t)=bcdot ln t+a (1).
We used the simplified equation (the KSV2 is assumed to be 0) to fit the decay time plots.
For example, when comparing with Hu1 scenario, by setting the lifetime in addition to the three key parameters mentioned above, the error on Hu1 results decreases from 24% (using the simplified model, Equation 4) to 4% (setting four variables out of nine in the complete reference model, Equation 3).
The grain growth kinetics was studied using the simplified phenomenological equation Gn = kte(−Q/RT).
In the ED, the patient's aortic valve area (AVA) was calculated, using the simplified continuity equation, at 0.28 cm2 [2].
Bedside pulsed-wave and continuous-wave Doppler ultrasound in the apical 5-chamber view revealed critical aortic stenosis using the simplified continuity equation.
From the melting point data of the high Tm component, a value for the polymer-polymer interaction of x12 = − 0.05 was derived using the simplified Nishi Wang equation.
The aortic valve area can be estimated with Doppler echocardiography using the simplified continuity equation [2, 3]: where CSA = the cross-sectional area [π(D diameter)/2)2] = 0.785D2, LVOT = left ventricular outflow tract, VelocityLVOT-Max = Maximal pulsed-wave Doppler velocity at the LVOT, and VelocityAV-Max = Maximal continuous-wave Doppler velocity through the AV.
