DuPont Pigment Dispersion in Liquids
Initial Wetting It is virtually impossible to disperse a material in a liquid that will not wet the surface of the material, e.g., aluminum stearate in water. However, most commercial pigments are fairly well wet by the vehicles used and differ appreciably only in their rates of wetting. This is usually evident in the latter stages of making a heavy paste; because, at this stage of mixing, ther...
متن کاملDuPont Chambers Works Waste Minimization Project
In a joint U.S. Environmental Protection Agency ( EPA) and DuPont waste minimization project, fifteen waste streams were selected for assessment. The intent was to develop assessments diverse in terms of process type, mode of operation, waste type, disposal needed, and relative success in identifying good waste reduction options. The fifteen case study reports describe the wastes and the proces...
متن کاملVerbal Disputes
Is there a distinction between questions of fact and questions of language? Many philosophers have said no. But a version of the distinction is ubiquitous, in philosophy and elsewhere, in the notion of a verbal dispute. Intuitively, a dispute between two parties is verbal when the two parties agree on the relevant facts about a domain of concern, and just disagree about the language used to des...
متن کاملNetworks & disputes
Networked systems often consist of inter-dependent subsystems that are governed by locally determined heterogeneous preferences or policies. Examples include interdomain routing, peer-to-peer storage, and decentralised security systems. This dissertation introduces a notion called dispute — a cyclic structure that underlies the dependence and preferences of subsystems. Disputes may cause advers...
متن کاملEvaluation of the DuPont aca amylase method.
The dilution/activity curve for the DuPont aca kinetic amylase (EC 3.2.1.1) method is linear to approximately six times the upper limit of the expected range. Total reaction time on the aca is 4.3 min; however, there is a nonlinear rate of change in absorbance for at least the first 8 min, which is consistent with a lag phase. The within-run and day-to-day coefficients of variation were 2.4% at...
