Nettet1. mai 2005 · The first aim of our analysis deals with the definition of the optimal method needed to investigate vesicle size distribution. Thus we started studying the intensity-weighted mean hydrodynamic radius 〈r〉 I by using both the second- and third-order cumulant expansions as well as the CONTIN inversion method. The results of the three … NettetEmail [email protected]. Objective: To investigate the value of the signal intensity on T2-weighted magnetic resonance (MR) imaging using quantitative analysis in the differentiation of parotid tumors. Materials and Methods: MR data of 80 pleomorphic adenomas (PAs), 68 Warthin tumors (WTs), and 34 malignant tumors (MTs) confirmed …

NettetThe intensity-weighted distribution is specific to the dynamic light scattering (DLS) technique. In that case, the results are expressed as a measure of the intensity fluctuations of the light scattered by the particle. Nettetcontinuous differential number-weighted distri-bution into a continuous differential volume-weighted distribution, multiply by D 3. The end result is a continuous volume-weighted differen-tial distribution. Of course the initial numerical values will not be normalized, but that is easy to remedy. Here is a simple example using con- ileaf naturals

NettetAs the results of DLS measurements are intensity-based (the intensity fluctuations over time are detected) this is the primary weighting model displayed in a DLS software. The … NettetD‾43 = the mean diameter over volume (also called the de Brouckere mean) The example results shown in ASTM E 799 are based on a distribution of liquid droplets (particles) ranging from 240 - 6532 µm. For this distribution the following results were calculated: D (1,0) = 1460 µm. D (3,2) = 2280 µm. D50 = 2540 µm.
