This paper studies the optimal management of groundwater resources when agronomic and hydrologic constraints bind the use of groundwater for irrigation. The binding constraints lead to a perfectly inelastic demand for groundwater. In the case of symmetric agents the social and private rates of...

Supplemental irrigation in corn production is increasing for humid regions across the world. Little is known about the profitability of irrigating corn in the humid southeastern region of the United States. Our objective was to determine the breakeven price of corn where investment in...

A new variational principle of steady states is found by introducing an integrated type of energy dissipation (or entropy production) instead of instantaneous energy dissipation. This new principle is valid both in linear and nonlinear transport phenomena. Prigogine’s dream has now been...

Some general aspects of nonlinear transport phenomena are discussed on the basis of two kinds of formulations obtained by extending Kubo’s perturbational scheme of the density matrix and Zubarev’s non-equilibrium statistical operator formulation. Both formulations are extended up to infinite...

A form of the transverse magnetic susceptibility of a ferromagnetic spin system with a uniaxial anisotropy energy and an anisotropic exchange interaction, interacting with a phonon reservoir, is derived in the spin-wave approximation using the TCLE method, where the phonon reservoir interacts...
