In previous chapters we considered the processes of advection and molecular diffusion and have seen some example problems with so called “turbulent diffusion” coefficients, where we use the same governing equations, but with larger diffusion (mixing) coefficients. In natural rivers, a host of processes lead to a non-uniform velocity field, which allows mixing to occur much faster than by molecu...

A finite poset is an angle order if its points can be mapped into angular regions in the plane so that x precedes y in the poset precisely when the region for x is properly included in the region for y. We show that all posets of dimension four or less are angle orders, all interval orders are angle orders, and that some angle orders must have an angular region less than 180” (or more than 180”...

Two-dimensional hybrid organic-inorganic Ruddlesden-Popper perovskites (RPPs) have attracted considerable attention due to their rich photonic and optoelectronic properties. The natural multi-quantum-well structure of 2D RPPs has been predicted to exhibit a large third-order nonlinearity. However, nonlinear optical studies on 2D RPPs have previously been conducted only on bulk polycrystalline s...

The CO2-brine dissolution homogenizes the distribution of residual CO2 and reduces the leakage risk in the saline aquifer. As a key parameter to immobilize the free CO2, the dissolution rate of CO2-brine could be accelerated through mechanisms like diffusion and dispersion, which are affected by the subsurface condition, pore structure, and background hydrological flow. This study contributed t...

In the tropical and subtropical coastal zone, were highly diverse fish communities occur, it is important to study the small scale fisheries exploiting these communities. For this study, 219 fishing days were carried out in Bahia de Navidad, Jalisco, Mexico. Four gillnets with different mesh sizes (76.2, 88.9, 101.6 and 114.3 mm) were used for the fishing operations, from April 1994 to March 19...

We report the lateral mobility of extrajunctional acetylcholine receptors (AChR), marked with fluorescently labeled alpha-bungarotoxin, on rat flexor digitorum brevis single muscle fibers maintained in cell culture. Mobility is measured by a modification of the fluorescence photobleaching recovery technique. The denervated rat flexor digitorum brevis muscle fibers exhibit a nonuniform distribut...

conclusions it can be concluded that electronic health records lead to a reduction in medication errors and increase patient safety. background medication errors are the most common medical errors, and are one of the major challenges threatening the healthcare system, which is inherently susceptible to error. objectives in this study, we aimed to compare the occurrence of errors between two met...

ELL BEFORE THE END of the eighteenth century, a conscious and deliberate discussion about self-image, that is, the way an artist sees himself, became a matter of course. Hence Mozart could write in 1778, at age twenty-two, “I am a Composer and was born a Capellmeister. I must not and cannot bury my gift for composing that a benevolent God has bestowed upon me in such a rich measure—I may say so...
