Microfluidic deterministic lateral displacement (DLD) arrays have been applied for fractionation and analysis of cells in quantities of ~100 μL of blood, with processing of larger quantities limited by clogging in the chip. In this paper, we (i) demonstrate that this clogging phenomenon is due to conventional platelet-driven clot formation, (ii) identify and inhibit the two dominant biological ...

A model for biofilm induced calcite precipitation with pressure driven flow is presented at the scale of a single pore within a porous medium. The system, an extension of previous work (Zhang and Klapper 2010 Water Sci. Technol. 61 2957–64, Zhang and Klapper 2011 Int. J. Non-Linear Mech. 46 657–66), is based on a mixture model including biomaterial, mineral, and water with dissolved components....

For studying plasma and red blood cell (RBc) electrolytes, we have developed a method that allows frequent accurate and reproducible sampling of both plasma and RBC. We determined that for our purposes, a 1.0-nil volume of sample was optimum. Although the 1.0-nil “Class A” Ostwald-Folin blow-out pipet and the standard “Class A” transfer pipet were adequate for sampling plasma, they were not ade...

In this study, the differences in soil filter clogging are evaluated under two operating conditions: constant head and constant flow rate. Whereas filters placed around well screens and leachate collection systems are subjected to a constant flow rate, filters in earth dams and pavement drainage systems operate under constant or slightly varying heads. In this study, the experiments revealed si...

Geo-synthetic materials are being used with acceptable performance in soil and water projects worldwide. Geotextiles are one of the categories of geo-synthetics being used in drainage systems. First generation of geotextiles used in the late 1950’s as an alternative for gravel envelopes. In this research two methods (multiple regression and fuzzy interference system) evaluate to predict synthet...

Magnetic skyrmions are promising for building next-generation magnetic memories and spintronic devices due to their stability, small size and the extremely low currents needed to move them. In particular, skyrmion-based racetrack memory is attractive for information technology, where skyrmions are used to store information as data bits instead of traditional domain walls. Here we numerically de...

Mathematical modeling and computer simulation methods have been used to investigate the extent of influence exerted by bio-clogging on dynamics excess head scattering in soil massif. To this end, classical equation filtration consolidation has modified for case variable porosity resulting from changes biomass. The numerical solution constructed mathematical model form a nonlinear boundary probl...

Infiltration filters of LID facilities are frequently confronted with clogging pores by contaminants. To avoid malfunctioning facilities, should be maintained according to the degree clogging. In this study, was characterized curves representing correlation between infiltration rate (<i>Q</i>) and quantity (<i>IR</i>). estimate clogging, a regression neural network model...

Drip fertigation systems are a new technology to alleviate water shortages and improve fertilizer use efficiency. Emitter clogging is the main obstacle their application. However, few efficient, safe, environmentally friendly methods available clogging. In this study, we explored effects of magnetized irrigation on emitter at different fertilization levels. Field experiments were conducted stud...

Clogging is one of the most important factors that restricts development and popularization artificial groundwater recharge technology. Gas clogging an but often overlooked form clogging. In this study, a high-speed image acquisition system was used to obtain high-resolution images migration water gas in pore. The bypass flow, trapped bubbles H-shaped pore channel, blind end, corner were direct...
