A Thermodynamic Formulation of Economics
The thermodynamic formulation of economics is based on the laws of calculus. Differential forms in two dimensions are generally not exact forms (δQ), the integral from (A) to (B) is not always the same as the integral from (B) to (A). It is possible to invest little in one way and gain a lot on the way back, and to do this periodically. This is the mechanism of energy production in heat pumps, ...
متن کاملRole of a single aquaporin isoform in root water uptake.
Aquaporins are ubiquitous channel proteins that facilitate the transport of water across cell membranes. Aquaporins show a typically high isoform multiplicity in plants, with 35 homologs in Arabidopsis. The integrated function of plant aquaporins and the function of each individual isoform remain poorly understood. Matrix-assisted laser desorption/ionization time-of-flight analyses suggested th...
متن کاملCalibration of a Two-Dimensional Root Water Uptake Model
mates of the temporal and spatial root water uptake patterns are needed. Quantification of root water exAlthough solutions of multidimensional transient water flow can traction rates also contributes to an improved underbe obtained by numerical modeling, their application may be limited in part as root water uptake is generally considered to be one-dimenstanding of chemical fluxes in the vadose...
متن کاملEvaluation of Macroscopic Root Water Uptake Models Using Lysimeter Data
Three macroscopic root water uptake models (Molz–Remson, Feddes, and Selim–Iskandar) have been widely used in modeling water flow in soil–plant systems. In this article, we use evapotranspiration data and soil water content data obtained from lysimeter measurements and root distribution data obtained in a nearby wheat field to evaluate the accuracy of these root water uptake models in predictin...
متن کاملRegulation of root water uptake under abiotic stress conditions.
A common effect of several abiotic stresses is to cause tissue dehydration. Such dehydration is caused by the imbalance between root water uptake and leaf transpiration. Under some specific stress conditions, regulation of root water uptake is more crucial to overcome stress injury than regulation of leaf transpiration. This review first describes present knowledge about how water is taken up b...
