Operation of the Gravimelt Integrated Test Circuit for desulfurization and demineralization of coal was completed in a previous quarter when a 48-test process matrix was performed over 750 hours of operational time resulting in the production of 3,000 pounds of treated coal suitable for further test and evaluation. Analysis of the large quantity of data collected continued during the current quarter. Assessment of trace elements in the feed and product coal for two runs (one with Pittsburgh No. 8 coal and one with Kentucky No. 9 coal) indicates that greater than 96% of the silicon, iron and aluminium was removed for both coals. A trace element analysis for 21 elements is presented in the quarterly. Selected samples of the product coal were placed in a GN{sub 2}-purged oven for six hours at 140{degree}F to remove about 15% of the moisture from the samples. These samples were repackaged in 55-gallon drums and shipped to DoE. Data from shakedown was analyzed in detail with particular attention paid to coal product quality (sulfur and ash), carbonate and humic acid formation, particle size distribution, liquid sample analysis, and wash train performance.

Nuclear instrumentation equipment was purchased for the reactor control room and reactor facility.

The information presented in this engineering note can be of value to others who wish to predict pumping times and water content of vessels containing G-IO material. Four predictions of the water content of the G-IO in the D-Zero Central Calorimeter (CC) are given. Experience from pumping on the NW A cryostat was used to help predict the pumpdown time required for the CC. The actual pumpdown time and water removal from the CC agrees quite well with those predicted which gives confidence for future predictions done using the information presented in this engineering note. A listing of the predictions and actual CC pumpdown particulars is given.

This project revolves around understanding the fundamental processes involved in the catalytic removal of harmful oxygenated organics present in coal liquids. We will model the complex type of sulfided Mo catalyst proposed for these reactions with a simple single crystal surfaces that display a controlled range and number of reaction sites and can be extensively characterized by surface science techniques.

Much work has been devoted to methods for reasoning about the specifications of operating system specifications, the goal being to develop specifications for an operating system that are verified to be secure. Before the verification should be attempted, the specifications should be tested. This paper presents tools that can assist in the security testing of specifications. The first tool is based on the final Algebra Specification and Execution (FASE) system, and would be used to test specifications with real input values. FASE is an executable specification language which is operational in style, in which entities are represented in terms of their observable behavior. To facilitate the testing of an operating system (and its specification), use FASE we have specified a Secure Resource Manager (SRM), a generic template of an operating system. The SRM specification can be specialized to a specification of a particular operating system; the SRM is quite general and handles most features of modern nondistributed operating systems. The second tool, called the PLANNER, is used to derive a sequence of operations that exhibits a security flaw, most often a covert channel for information flow. The PLANNER is based on classical methods of AI planning, specialized to achieve goals …

To determine the effect of alternate catalysts on the synthesis. This will include copper chromite catalysts impregnated with alkali metals such as potassium, rubidium and cesium as well as their use as homogenous catalysts in the form of methoxides or similar salts. The use of various copper chromite catalysts with different compositions will be studied: e.g. substituting barium for manganses in copper chromite catalyst has a beneficial effect. To determine the nature of the active catalysts in this reaction and the effect of deactivating agents such as CO{sub 2}, H{sub 2}O and CO. To determine the rate limiting steps in this reaction so that proper scale-up is possible. The effects of catalysts loading and reactor volume are of special importance. To develop mathematical models which can be used for prediction of rates of reaction and are suitable for scale-up of the reaction.

Thin-layer chromatography (TLC) is a broadly applicable separation technique. It offers many advantages over high performance liquid chromatography (HPLC), such as easily adapted for two-dimensional separation, for whole-column'' detection and for handling multiple samples, etc. However, due to its draggy development of detection techniques comparing with HPLC, TLC has not received the attention it deserves. Therefore, exploring new detection techniques is very important to the development of TLC. It is the principal of this dissertation to present a new detection method for TLC -- indirect fluorometric detection method. This detection technique is universal sensitive, nondestructive, and simple. This will be described in detail from Sections 1 through Section 5. Section 1 and 3 describe the indirect fluorometric detection of anions and nonelectrolytes in TLC. In Section 2, a detection method for cations based on fluorescence quenching of ethidium bromide is presented. In Section 4, a simple and interesting TLC experiment is designed, three different fluorescence detection principles are used for the determination of caffeine, saccharin and sodium benzoate in beverages. A laser-based indirect fluorometric detection technique in TLC is developed in Section 5. Section 6 is totally different from Sections 1 through 5. An ultrasonic effect on the separation of …

Reaction pathways leading to the formation and cleavage of a transition metal-carbon bond at various oxidation states of the metal occupy a central position in understanding many enzymatic reactions and designing catalysts. The report is divided into six parts that (1) focus on the homolysis vs heterolysis of a C-Cr(III) bond, (2) describes a unique chain reaction and a S{sub E}2 reaction I{sub 2} and RCrL{sup 2+}, (3) concerns the oxidation of organochromium(III) complexes by dihalide and pseudo-dihalide radical anions generated by pulse radiolysis, (4) concentrates on the oxidation mechanism of RCr(H{sub 2}O){sup 2+} and the fate of RCr(H{sub 2}O){sup 3+} as well as the corresponding reduction potentials, (5) extends study of organocobalt complexes with attention to reduction induced cleavages of a transition metal-carbon bond, and (6) describes the crystallization of ((CH{sub 3}){sub 4}N)(Co(dmgBF{sub 2}){sub 2}py) and reports its molecular structure as determined by x-ray diffraction. 182 refs., 25 figs., 16 tabs.

During the 1988/1989 run at the Fermilab Tevatron, the CDF detector collected {approx equal}4.1 pb{sup {minus}1} of p{bar p} data at {radical}s = 1.8 TeV. The main goals of this run being physics at high p{sub t}, the CDF trigger was tuned'' for maximizing signals from Z{sup 0}s, Ws, t-quarks, etc. As such, compared to the high p{sub t} physics, the b-physics program was of secondary importance other than that which would be used for background calculations. Also, CDF had no vertex chamber capability for seeing displaced vertices. However, significant b-quark, physics results are evident in two data samples; inclusive electrons and inclusive J/{psi} where J/{psi} {yields} {mu}{sup +}{mu}{sup {minus}}. We can then ask ourselves, given all this, why is it that CDF is able to do b-quark physics The answer is that nature has been kind enough to provide b-quarks at an extremely high rate at the Tevatron. The production cross-section for b{bar b} production is quite large. In the rest of this paper, I will try to specify the goals for b-physics using the inclusive electrons and J/{psi} signals for the 1988/1989 data set. I will then provide a brief look at the data, and will finish with …

In this paper we report recent QCD analysis with the new data taken from CDF detector.

The major topics of this report are inclusive jet, dijet, trijet and direct photon analysis. These measurements are compared of QCD predictions. For the inclusive jet an dijet analysis, tests of quark compositeness are emphasized. 11 refs., 6 figs.

Experiment E760 has a lead glass (Pb-G) calorimeter situated in the antiproton source tunnel in the accumulator ring at location A50. This location is exposed to radiation from several sources during antiproton stacking operations. A series of radiation studies has been performed over the last two years to determine the sources of this radiation and as a result, some shielding has been installed in the antiproton source in order to protect the lead glass from radiation damage.
