Droplet-based programmable processors promise to offer solutions to a wide range of applications in which chemical and biological analysis and/or small-scale synthesis are required, suggesting they will become the microfluidic equivalents of microprocessors by offering off-the-shelf solutions for almost any fluid based analysis or small scale synthesis(More)
groupers and their associated reef fish assemblage near cape fear, north carolina, were observed using scuba and underwater stationary videography during a 7-mo period. fifty-seven sites were visited with stationary video and diver point counts of groupers were taken at each site. primary observations by both techniques were made on gag, Mycteroperca(More)
A high-voltage (HV) integrated circuit has been demonstrated to transport droplets on programmable paths across its coated surface. This chip is the engine for a dielectrophoresis (DEP)-based micro-fluidic lab-on-a-chip system. This chip creates DEP forces that move and help inject droplets. Electrode excitation voltage and frequency are variable. With the(More)
A high-voltage (HV) integrated circuit has been demonstrated to transport fluidic droplet samples on programmable paths across the array of driving electrodes on its hydrophobically coated surface. This exciter chip is the engine for dielectrophoresis (DEP)-based micro-fluidic lab-on-a-chip systems, creating field excitations that inject and move fluidic(More)
Diagnosis and treatment of human diseases frequently requires isolation and detection of certain cell types from a complex mixture. Compared with traditional separation and detection techniques, microfluidic approaches promise to yield easy-to-use diagnostic instruments tolerant of a wide range of operating environments and capable of accomplishing(More)
The Extractive Industries Transparency Initiative (EITI) has now become a standard for improving transparency and accountability in the majority of mineral and metals (mining) rich countries. There are a number of feature of the mining sector (as opposed to the oil and gas sectors) which significantly influence how the EITI is implemented in such countries.(More)
