In this paper, we obtain the continuous dependence and convergence results for the Brinkman and Forchheimer coefficients of a differential equation that models the flow of fluid in a saturated porous medium.
One very encouraging development has been the freedom with which amino acid replacements can be introduced in a protein of interest. This has made it possible to obtain detailed structural and thermodynamic data on a wide variety of mutants that modify protein stability. Substitutions of solvent-exposed amino acids on the surfaces of proteins are seen to have little if any effect on protein sta...
INTRODUCTION The fact that polyacetylene (PA) [C2H2]∞ is isoelectronic with polycarbonitrile (PCN) [CHNH]∞ has caused many theoretical studies to investigate the later compound in diverse levels of theories, but using a fully trans structure [1], since this is the most stable structure for PA. More recent studies of the structural and thermodynamic stability using PCN in fully trans, cis-transo...
We have studied stability of lithium-manganese oxides using density functional theory in the local density and generalized gradient approximation ~GGA!. In particular, the effect of spin-polarization and magnetic ordering on the relative stability of various structures is investigated. At all lithium compositions the effect of spin polarization is large, although it does not affect different st...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
Comparing the Effects of Vetiver and Polyacrylamide on Soil Structural Stability and Erosion Indices
Extended abstract 1- INTRODUCTION Soil erosion is one of the most important problems of the environment, natural resources, and agriculture in the world. Soil structure stability is the key element of soil health, the main factor in the improvement or degradation of soils, and the important point in evaluating the effects of land management and the operations practices to control soil ero...

The effect of the sugars sucrose, glucose, and trehalose on the structural and colloidal stability of lysozyme has been investigated using differential scanning calorimetry and quasi-elastic light scattering, respectively. While sugars are known to increase the temperature at which thermal denaturation of protein occurs, it is not clear if, under the same solution conditions, greater colloidal ...
The thickness-dependent electronic states and physical properties of two-dimensional materials suggest great potential applications in electronic and optoelectronic devices. However, the enhanced surface effect in ultra-thin materials might significantly influence the structural stability, as well as the device reliability. Here, we report a spontaneous phase transformation of gallium telluride...
