The overall objective of this project was to determine the cost and impacts of Hg control using sorbent injection into a Compact Hybrid Particulate Collector (COHPAC) at Alabama Power's Gaston Unit 3. This test is part of a program funded by the U.S. Department of Energy's National Energy Technology Laboratory (NETL) to obtain the necessary information to assess the costs of controlling Hg from...

The ability of a nitride light-emitting diode (LED) to withstand electrostatic discharge (ESD) is important because of the insulating property of the sapphire substrate. Therefore, damage caused by ESD to a nitride LED is a valuable subject. However, damage is caused by ESD in a very short period, so monitoring its evolution is very difficult. Accordingly, ESD experiments are performed and the ...

Introduction Posterior reversible encephalopathy syndrome (PRES) is a rare disease with a diverse range of precipitants. The cause is not well understood. We report a case of PRES that occurred soon after exposure to oxaliplatin and 5-fluorouracil, in which the patient presented with mild symptoms and normal blood pressure, but progressed to a severe condition with associated hypertension. The ...

A thermostable beta-glycosidase (Tn-gly) from Thermus nonproteolyticus HG102 has been cloned and overexpressed in Escherichia coli. The recombinant enzyme, with a molecular mass of 48.9 kDa, was purified to homogeneity. It can hydrolyze a wide range of oligosaccharides and perform transglycosylation. Crystals of the recombinant enzyme were grown by the hanging-drop vapour-diffusion technique wi...

Altered mental status is a common chief compliant among older patients in the emergency department (ED). Acute changes in mental status are more concerning and are usually secondary to delirium, stupor, and coma. Although stupor and coma are easily identifiable, the clinical presentation of delirium can be subtle and is often missed without actively screening for it. For patients with acute cha...

Let u be the equilibrium potential of a compact set K in R. An electrostatic skeleton of K is a positive measure μ such that the closed support S of μ has connected complement and no interior, and the Newtonian (or logarithmic, when n = 2) potential of μ is equal to u near infinity. We prove the existence of an electrostatic skeleton for every convex polytope. Our proof raises several interesti...

personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. this work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. velocity profiles have been measured around and within typical cylindrical sampling devices, plac...

Fly ash (FA) and Air Pollution Control (APC) residues collected from three municipal solid waste incinerators (MSWI) in Denmark and Greenland were treated by electrodialytic remediation at pilot scale for 8 to 10 h. The original residues and the treated material were analysed for mercury (Hg) in order to assess the influence of the electrodialytic treatment on the concentrations of this element...

The description of molecular systems using multipolar electrostatics calls for automated methods to fit the necessary parameters. In this paper, we describe an open-source software package that allows fitting atomic multipoles (MTPs) from the ab initio electrostatic potential by adequate atom typing and judicious assignment of the local axis system. By enabling the simultaneous fit of several m...

In the paper a review is given of the current state of the art of micromachined inertial sensors accelerometers and gyroscopes. These sensors can be used in a wide range of applications and micromachined devices have a number of significant advantages over their conventional counterparts such as lower cost, smaller form factor and lower power consumption. An overview will be given over the dive...
