Analysis of Low Density Particles Using Differential Centrifugal Sedimentation
Centrifugal sedimentation of particles suspended in a fluid is a well known method (1, 2) to measure the size distribution of particles in the range of about 0.02 micron to about 20 microns. The sedimentation velocity of any particle can be calculated if the particle density, fluid density, fluid viscosity, and centrifugal acceleration are known, using the well known Stokes' Equation (3). Stoke...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

It is demonstrated that the adsorption of bovine serum albumin (BSA) to aqueous gold colloids can be quantified with molecular resolution by differential centrifugal sedimentation (DCS). This method separates colloidal particles of comparable density by mass. When proteins adsorb to the nanoparticles, both their mass and their effective density change, which strongly affects the sedimentation t...
متن کاملMeasuring relative equality of concentration between different income/wealth distributions
In a recent paper Burrell (2005a) introduced two new measures both based on the Gini mean difference for measuring the similarity of concentration of productivity between different informetric distributions. The first was derived from Dagum’s (1987) notion of relative economic affluence (REA); the second – in some ways analogous to the correlation coefficient – is a new approach giving the so-c...
