Synergistic capture mechanisms for alkali and sulfur species from combustion (open access)

Synergistic capture mechanisms for alkali and sulfur species from combustion

This report presents work done on a laboratory combustor in an attempt to identify mechanisms that govern the simultaneous capture of alkali and sulfur species using sorbent injection techniques. The mechanisms of capture fall into two broad categories i.e. Physical transport of alkali species (in vapor or condensed phase) to the sorbent surface and surface reaction between the alkali species and the sorbents. Water solubility, though not specific, has been used to get an indication of relative significance of these two broad mechanisms. It is assumed that the physically adsorbed alkali species on sorbents are predominantly water soluble while the chemically reacted alkali content is predominantly water insoluble. In order to infer possible dominant mechanisms, specific parameters has been varied during experimentation. Such parameters include, speciation, particle time-temperature history, and furnace burning conditions.

Photocopy of a letter from Leilani Lattin Duke, Director of the Getty Center, to Bonnie Bernau, Very Special Arts. In discussion of Bernau's involvement with developing Creating and Beyond: Arts Education for a Changing World. However, due to the Center's changes in educational environment and demands on resources they've decided not to proceed with the publication of the work, but thank Bernau for the contribution made to the project. As consolation to Bernau's efforts, the Center would like to invite her to the upcoming national conference, "Education for the Workplace through the Arts."

A beam profile monitor for small electron beams (open access)

A beam profile monitor for small electron beams

Measurement of beam properties at the foci of high energy linacs is difficult due to the small size of the waists in proposed and existing accelerators (1 nm {minus} 2 {mu}). This paper considers the use of bremsstrahlung radiation from thin foils to measure the size and phase space density these beams using nonimaging optics. The components of the system are described, and the ultimate resolution, evaluated theoretically for the case of the Final Focus Test Beam at Stanford Linear Accelerator Center, is a few nm. 13 refs., 4 figs. 1 tab.

Development of instrumentation for magnetic nondestructive evaluation (open access)

Development of instrumentation for magnetic nondestructive evaluation

The use of failure-prone components in critical applications has been traditionally governed by removing such components from service prior to the expiration of their predicted life expectancy. Such early retirement of materials does not guarantee that a particular sample will not fail in actual usage. The increasing cost of such life expectancy based operation and increased demand for improved reliability in industrial settings has necessitated an alternate form of quality control. Modern applications employ nondestructive evaluation (NDE), also known as nondestructive testing (NDT), as a means of monitoring the levels and growth of defects in a material throughout its operational life. This thesis describes the modifications made to existing instrumentation used for magnetic measurements at the Center for Nondestructive Evaluation at Iowa State University. Development of a new portable instrument is also given. An overview of the structure and operation of this instrumentation is presented. This thesis discusses the application of the magnetic hysteresis and Barkhausen measurement techniques, described in Sections 1.3.1 and 1.3.2 respectively, to a number of ferromagnetic specimens. Specifically, measurements were made on a number of railroad steel specimens for fatigue characterization, and on specimens of Damascus steel and Terfenol-D for materials evaluation. 60 refs., 51 figs., …

Evaluation of Effectiveness of the Turco Low Profile Turbulator Reg Sign (open access)

Evaluation of Effectiveness of the Turco Low Profile Turbulator Reg Sign

This document discusses a turbulator which utilizes a heated chemical bath to reduce smearable contamination from small parts and tools. It is comprised of two agitators programmed to automatically alternate the flow of the cleaning solution within the tank in four separate and distinct high velocity flow patterns allowing access to the entire surface area of the part or tool being decontaminated. The turbulator is being evaluated to determine if agitation increases the effectiveness of waste minimization. Testing of the turbulator consisted of evaluation of the Sludgetrap Containment, Tool Cleaning Demonstration, and Coupon Testing. Results so far are that the sludgetrap is effective in containing particles the size of sand, agitation increases the effectiveness of the turbulator, abrasives can replace detergents for waste minimization, and Inconel 625 is more difficult to clean than Type 3041 Stainless Steel.

(Study of flow properties of wet solids using laser induced photochemical anemometry)

Research continues on the flow properties of wet solids. During this period we have made: progress in the analysis of the accuracy of the technique, progress in firming the foundations of LIPA for Solid-Liquid Mixtures, progress in the construction of better prototype skimmers, continued progress in chemically manufacturing both more red europium imbedded CaF{sub 2} and Green liquid Flowlite, and progress in understanding the coupling of LIPA chemicals snd dynamic range and timing.
