Partially elastic model

Impact. Using a simple partial equilibrium model of rice supply and demand, Minten and Dor-osh (2006) show that lowering the rice import tariff by 10 percentage points would have had only a small effect on total revenues collected, because even with inelastic overall consumer demand, import demand is price elastic. The reduction in the tariff increases the demand for rice by 14 to 24 percent, depending on the assumed magnitude of the own-price elasticity of demand. If producers are also price responsive, the effect on total tariff revenue is even smaller only a 6 percent decline. The net benefits of this policy for net consumers would be between US 8.5 million and US 8.8 million, although the net benefits to all the poor, including rural surplus households, are only US 0.6 million to US 1.3 million.

The writer45 60 has criticized the elasticity theory model on the basis that this partial character renders the theory unverifiable by experiment, unless this model is correlated with another model that may be postulated to represent the negative portion of the AH, a correlation which has never been achieved. Another criticism has been the inconsistency of the model when it is applied to the case of solute atom smaller than the solvent atom, as opposed to... 

The prerequisite for an experimental test of a molecular model by quasi-elastic neutron scattering is the calculation of the dynamic structure factors resulting from it. As outlined in Section 2 two different correlation functions may be determined by means of neutron scattering. In the case of coherent scattering, all partial waves emanating from different scattering centers are capable of interference the Fourier transform of the pair-correlation function is measured Eq. (4a). In contrast, incoherent scattering, where the interferences from partial waves of different scatterers are destructive, measures the self-correlation function [Eq. (4b)]. 

If Gc chains crystallize (partially) there will remain G-Gc completely amorphous chains and G + 3Gc/2 total elastic elements (amorphous chains and subchains). This is true only for the model described with 1/2 Gc chains folding once and 1/2 Gc chains not folding at all. If each elastic element is Gaussian in its behavior, the elastic free energy Fg can be written as... 

Elasticity experiments rely on the developed turnover approximation method. The following model performance tests investigate the influence of partial quantity points on approximation accuracy and solution time. The more sections subdivide spot sales quantities into partial quantities, the better the approximation, but the more constraints and decision variables are required. 

As with the elastic solid we can see that as the stress is applied the strain increases up to a time t = t. Once the stress is removed we see partial recovery of the strain. Some of the strain has been dissipated in viscous flow. Laboratory measurements often show a high frequency oscillation at short times after a stress is applied or removed just as is observed with the stress relaxation experiment. We can replace a Kelvin model by a distribution of retardation times ... 

The tubule is a spatially extended structure, and it presents both elastic properties and resistance to the fluid flow. The dynamic pressure and flow variations in such a structure can be represented by a set of coupled partial differential equations [11]. An approximate description in terms of ordinary differential equations (a lumped model) consists of an alternating sequence of elastic and resistive elements, and the simplest possible description, which we will adopt here, applies only a single pair of such elements. Hence our model [12] considers the proximal tubule as an elastic structure with little or no flow resistance. The pressure P, in the proximal tubule changes in response to differences between the in- and outgoing fluid flows ...
