It is found in important quantities in Switzerland, Germany, Romania, the Czech Republic, France, Peru, and Chile, and both minerals occur in large amounts in Colorado, Idaho, and other localities in the western United States.
Recovery of H2, available in important quantities, is also considered.
Variscite occurs in Germany, Austria, Czech Republic, Congo (Kinshasa), and Australia and in commercially important quantities near Fairfield, Utah, U.S. It also occurs with apatite on islands where phosphatic solutions from guano (seafowl excrement) have altered aluminous igneous rocks.
Seashell By-Products (SBP) are produced in an important quantity in France and are considered as waste.
In the present paper we develop an artificial neural network (ANN) in order to make accurate short-term predictions for several important quantities in a large landfill in southern California, including the temperature, and the CH4, CO2, and O2 concentration profiles.
In classical molecular dynamics free energy is one of the most important quantities in analyzing a molecular system.
In addition to the practically infinite mixtures of hydrocarbon compounds that form crude oil, sulfur, nitrogen, and oxygen are usually present in small but often important quantities.
In the 1990's he opened a new front in his research, with highly original ideas for applying seemingly unrelated "abstract" mathematics to the efficient calculation of important quantities in quantum physics.
Important quantities in fracture mechanics, such as crack surface displacement, stress intensity factor and energy release rate, are explicitly presented.
In this section, we consider the generating function of the time to ruin, which is one of important quantities in risk analysis.
The thickness and composition of the chest wall are important quantities in multiparametric trauma models for the assessment of injury severity due to blunt ballistic chest impact.
