INTRODUCTION The Privacy Rule of Health Insurance Portability and Accountability Act requires that clinical documents be stripped of personally identifying information before they can be released to researchers and others. We have been developing a software application, NLM Scrubber, to de-identify narrative clinical reports. METHODS We compared NLM Scrubber with MIT's and MITRE's de-identifi...

original paper   the mass-transfer media plays a significant role on the performance of a packed tower. in this paper three counter-current single-stage packed towers at laboratory scale, randomly packed with two different sizes of two types of packing material were experimentally tested to study the role of the packing on the performance of them in the removal of sulfuric acid mists. gas sampl...

A semi-continuous and automated method for quantifying atmospheric ammonia at the parts per billion level has been developed. The instrument consists of a high efficiency diffusion scrubber, an electrolytic on-line anion exchange device, and a conductivity detector. Water soluble gases in sampled air diffuse through the porous membrane and are absorbed in an absorbing solution. Interferences ar...

Particle collection efficiencies in 23 size intervals covering a diameter range of 0.32-2.8 pm were measured for venturi scrubbers with throat diameters of 3.2,5.4, and 7.6 cm. Each scrubber was operated with four types of liquid injection, throat gas velocities from 21 to 160 m/s, and liquid-to-gas volume ratios from 0.000 19 to 0.0043. Results were compared to three widely used theoretical mo...

Abstract—Wet scrubbers have found widespread use in cleaning contaminated gas streams because of their ability to remove particulates and based on the applications of scrubbing of marine engine exhaust gases by spraying sea-water. In order to examine the flow characteristics inside the scrubber, the model is designated with flow properties of hot air and water sprayer. The flow dynamics of evap...

The Scrubber is a general controller for friction-induced sound. Allowing the user to engage in familiar gestures and feeling actual friction, the synthesized sound gains an evocative nature for the performer and a meaningful relationship between gesture and sound for the audience. It can control a variety of sound synthesis algorithms of which we demonstrate examples based on granular synthesi...

The shipping sector is a significant contributor to emissions of air pollutants in marine and coastal regions. In order to achieve sustainable shipping, primarily through new regulations and techniques, greater knowledge of dispersion and deposition of air pollutants is required. Regional model calculations of the dispersion and concentration of sulfur, nitrogen, and particulate matter, as well...
