Based on data from the 1997 Investigación sobre Materia Particulada y Deterioro Atmosférico-Aerosol and Visibility Evaluation Research (IMADA-EVER) campaign and the inorganic aerosol model ISORROPIA, the response of inorganic aerosols to changes in precursor concentrations was calculated. The aerosol behavior is dominated by the abundance of ammonia and(More)
Carbon capture and storage (CCS) is a critical technology for reducing greenhouse gas emissions from electricity production by coal-fired power plants. However, full capture (capture of nominally 90% of emissions) has significant impacts on the technology, plant performance, and project economics that represent challenges for the first movers who implement(More)
This paper presents the probabilistic collocation method as a computationally efficient method for performing uncertainty analysis on large complex models such as those used in global climate change research. The collocation method is explained, and then the results of its application to a box model of ocean thermohaline circulation are presented. A(More)
We have derived a parameterization consisting of a set of analytical expressions that approximate the predictions by the CIT Urban Airshed Model for the net export to the environment (i.e., effective emissions) of several chemical species, as functions of fourteen input parameters. For each species, effective emissions are a function of actual urban(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract Post combustion absorption technologies represent one of the most commercially ready technologies for CO 2 capture. Solvent selection is the critical consideration in post-combustion absorption capture technology. In order to(More)
Amyloid fibrillation has been intensively studied because of its association with various neurological disorders. While extensive time-dependent fibrillation experimental data are available and appear similar, few mechanistic models have been developed to unify those results. The aim of this work was to interpret these experimental results via a rigorous(More)
Dear Sirs: In his letter (ES&T, Vol. 15, No. 11, 1981, p. 1250), Dr. Needleman questions Dr. Jerome Cole's views on the grounds that they were based upon studies ". . . supported by lead industry funds." Since when in the U.S. is the accused denied the right to have his evidence presented and fairly evaluated rather than summarily dis­ missed as biased on(More)
