Development of a multi-compartment population balance model for high-shear wet granulation with discrete element method [PDF]

open access: yes, 2017
This paper presents a multi-compartment population balance model for wet granulation coupled with DEM (discrete element method) simulations. Methodologies are developed to extract relevant data from the DEM simulations to inform the population balance ...

The Michaelis-Menten-Stueckelberg Theorem

open access: yesEntropy, 2011
We study chemical reactions with complex mechanisms under two assumptions: (i) intermediates are present in small amounts (this is the quasi-steady-state hypothesis or QSS) and (ii) they are in equilibrium relations with substrates (this is the ...

Use of chemical totalizer of radiation in energy balance measurements

open access: yesSilva Fennica, 1978
The investigation is concerned with testing chemical totalizer of radiation (Frankfurt radiometer) for use in measuring the components of a simple energy balance (latent heat = net radiation – sensible heat) so as to gain an estimate for evaporation ...

About Some Properties and Constructions of Experimental Designs

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2016
In this paper, we consider the problems related to the determining plan of the experiment performed according to the model of the chemical balance weighing design under additional assumption that the experimental errors are equally negatively correlated.

Enhanced chemical weathering of rocks during the last glacial maximum: a sink for atmospheric CO2? [PDF]

open access: yes, 1999
It has been proposed that increased rates of chemical weathering and the related drawdown of atmospheric CO2 on the continents may have at least partly contributed to the low CO2 concentrations during the last glacial maximum LGM..

Thermodynamic evolution theorem for chemical reactions

open access: yesPhysical Review Research, 2020
The production, exchange, and balance of entropy characterize the thermodynamics of open nonequilibrium systems, ranging from chemical reactions, cells, ecological systems, and Earth-like planets to stars.

Chemical Compositions and Source Analysis of PM2.5 during Autumn and Winter in a Heavily Polluted City in China

open access: yesAtmosphere, 2020
As one of the biggest cities in North China, Jinan has been suffering heavy air pollution in recent decades. To better characterize the ambient particulate matter in Jinan during heavy pollution periods, we collected daily PM2.5 (particulate matter with ...

Influence of chemical denudation on hillslope morphology [PDF]

open access: yes, 2004
[1] Models of hillslope evolution involving diffusion-like sediment transport are conventionally presented as an equation in which the changes in land-surface elevation or soil thickness are balanced by the divergence of soil transport and tectonic ...

DNA Balance for Native Characterization of Chemically Modified DNA [PDF]

open access: yes, 2021
Chemical modification is a powerful approach to expand the chemical diversity and functionality of natural DNA. However, when chemically modified oligonucleotides are employed in DNA-based reactions or structures, it becomes quite difficult to predict ...
