Activated Charcoal—A Potential Material in Glucoamylase Recovery

Activated Charcoal—A Potential Material in Glucoamylase Recovery

The potential of activated charcoal in the purification of fungal glucoamylase was investigated. Various concentrations of activated charcoal (1-4% w/v) were used to concentrate crude glucoamylase from Rhizopus oligosporus at different temperature values (30-50°C). Effects of pH (3.0-6.0) and contact time (0-60 min) on enzyme purification were also monitored. Activated charcoal (3% w/v) gave a ...

On Shape and Material Recovery from Motion

We present a framework for the joint recovery of the shape and reflectance of an object with dichromatic BRDF, using motion cues. We show that four (small or differential) motions of the object, or three motions of the camera, suffice to yield a linear system that decouples shape and BRDF. The theoretical benefit is that precise limits on shape and reflectance recovery using motion cues may be ...

Recovery of Dna from Adhesive Material

Latent fingerprints are commonly recovered from crime scenes using tape lifts. Advancements in the sensitivity of DNA testing allow for DNA profiles from these “touch”, tape lift samples to be obtained. One drawback to DNA typing of tape lifts is that the adhesive material on the tape may inhibit DNA recovery. The purpose of this study was to maximize the recovery of DNA from the adhesive mater...

Inhomogeneity Material Effect on Electromechanical Stresses, Displacement and Electric Potential in FGM Piezoelectric Hollow Rotating Disk

In this paper, a radially piezoelectric functionally graded rotating disk is investigated by the analytical solution. The variation of material properties is assumed to follow a power law along the radial direction of the disk. Two resulting fully coupled differential equations in terms of the displacement and electric potential are solved directly. Numerical results for different profiles of i...
