A new approach for estimating motion in microfluidic flows is presented. Is is based on an extension of the brightness changes constraint equation (BCCE) to incorporate Taylor dispersion. This extended BCCE is then used for accurately estimating fluid flows in a two dimensional Molecular Tagging Velocimetry (2D-MTV) framework. Reference measurements were conducted to validate the accuracy and a...

We report the experimental results that show the operation of superconducting quantum interference device (SQUID) microsusceptometers immersed in the (3)He-(4)He mixture inside the mixing chamber of a dilution refrigerator at high frequency (1 MHz) and down to very low temperatures (13 mK). The devices are based on highly sensitive and easy-to-use commercial SQUID sensors. The integrated suscep...

Detailed stratigraphic sampling of formations from Somma-Vesuvius (Southern Italy) volcano complex erupted during the last 3550 years of inteplinian activity provide a framework for comprehensive chemical analyses and isotopic studies. The evolution of majorand trace-element abundances of these rocks suggest that fractional crystallization together with crustal assimilation are only a partial e...

Understanding mixing processes that occur in the human vitreous chamber is of fundamental importance due to the relevant clinical implications in drug delivery treatments of several eye conditions. In this article we rely on experimental observations (which demonstrated that dispersion coefficients largely dominate diffusive coefficients) on a physical model of the human eye to perform an analy...

There are currently no practical systems that allow extended regions (>5 mm(2)) of a tissue slice in vitro to be exposed, in isolation, to changes in ionic conditions or to pharmacological manipulation. Previous work has only achieved this at the expense of access to the tissue for recording electrodes. Here, we present a chamber that allows a tissue slice to be maintained in multiple solutions...

The purpose of this paper is to present an experimental setup developed to characterize reactions between ozone and building products and document their potential impact on indoor air quality. Preliminary experiments were conducted on four building products: two carpets, a gypsum board and a pine wood board. These preliminary experiments clearly indicate that ozone is significantly removed in c...

Understanding the formation mechanisms of secondary air pollution is very important for formulation control countermeasures in China. Thus, a large-scale outdoor atmospheric simulation smog chamber was constructed at Chinese Research Academy Environmental Sciences (the CRAES Chamber), which designed simulating photochemical processes under conditions close to real environment. The consisted 56-...
