This paper discusses: neutrino interactions at LAMPF; parity violation in polarized ep scattering; and superconducting detector development.

Coal Technology Corporation (CTC) believes that the new CTC high gravity, high production, batch type centrifugal dryer technology can play a significant role in improving the product quality as well as costs of operation in coal processing plants. It is further believed that the new centrifugal dryer technology can form an important part in systems used to clean up the millions of tons of coal fines in refuse piles and ponds. It is anticipated that the new centrifuge can become an important ancillary to the advanced deep cleaning processes for coal. Because of these convictions, CTC has been engaged in a pioneering research effort into the new art of drying fine clean coal in high gravity, high production, batch type centrifuges, since 1981. This work has progressed to the point where the new centrifugal dryer technology is nearly ready for commercialization. It promises to provide needed fine coal drying capability at somewhat lower capital costs and at substantially lower operating costs than competitive systems. It also promises to do so with no detrimental effects on either the coal quality or the evironment. The primary objective of this project is to prove the concept in a commercial coal processing plant environment. …

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Jim Mattox, regarding a legal question submitted for clarification: Authority of a commissioners court to award "design/build" contracts for construction of public buildings on the basis of competitive bids and related questions (RQ-1895)

TCNQ Charge Transfer Complexes with Coals. TCNQ can be readily deposited in coals from pyridine solution. IR spectra of TCNQ and TCNQ in Illinois No. 6 coal are shown in Fig. 1. It is clear that the stretching frequency has been shifted by the full 44 cm{sup {minus}1} caused by the transfer of a single electron. Similar behavior has been observed with a variety of coals, including lignites, subbituminous and a range of bituminous coals. There are two possible explanations for the observed shift. The simplest explanation is that there exist in coals structures which are excellent single electron donors capable of transferring an electron to TCNQ in the ground state. All of the TCNQ dissolved in the coal is shifted. No uncomplexed TCNQ remains in the sample, as demonstrated by the absence of the unaltered CN stretch at 2227 cm{sup {minus}1}. The spectrum shown is for TCNQ in coal in a molar concentration equivalent to approximately 20% of the PNA systems in this coal as deduced from the NMR studies of Solum et al. (1989). It is highly unlikely that 20% of the PNA systems in coal are such good electron donors that the charge transfer complex would have …

This project is designed to develop methods for pre-combustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic solvent. Enzymes from commercial sources or microbial extracts are being investigated for their capacity to remove organic sulfur from coal by oxidation of the sulfur groups, splitting of C-S bonds and loss of sulfur as sulfuric acid. Dibenzothiophen (DBT) and ethylphenylsulfide (EPS) are serving as models of organic sulfur-containing components of coal in initial studies.

Highlights of the DIII-D Research Operations task are: completed five weeks tokamak operations; initiated summer vent; achievement of 10.7% beta; carried out first dimensionless transport scaling experiment; completed IBW program; demonstrated divertor heat reduction with gas puffing; field task proposals presented to OFE; presentation of DIII-D program to FPAC; made presentation to Admiral Watkins; and SAN safety review. Summaries are given on research programs, operations, program development, hardware development, operations support and collaborative efforts. Brief summaries of progress on the International Cooperation task include: TORE SUPRA, ASDEX, JFT-2M, and JET. Funding for work on CIT physics was received this quarter. Several physics R and D planning tasks were initiated. Earlier in FY90, a poloidal field coil shaping system (PFC) was found for DIGNITOR. This quarter more detailed analysis has been done to optimize the design of the PFC system.

During this period, the ARIES-I blanket design team completed the preparation of the ARIES-I reactor design final report. The helium-cooled, lithium breeder, SiC composite structure blanket option for the ARIES-II was evaluated and it was found that the corrosion resistance of the SiC in lithium is very poor. At the direction of DOE/OFE, the ARIES team was directed to defer work on the ARIES-II and to begin work immediately on the ARIES-III advanced fuel (D-{sup 3}He) tokamak design. Also, Varian EIMAC completed fabrication of two X2274 tetrode tubes and shipped them to Japan for testing on schedule. JAERI carried out the testing and both tubes operated successfully above specifications. The US and Chinese beryllium shells were shipped to Osaka University in Japan, beginning the second phase of the ``Coordinated U.S./PRC, U.S./Japan and Japan/PRC Fusion Neutron Integral Experiments.`` New fusion nuclear data experiments are being initiated for O(n,alpha) and Tc{sup 99}(n,p) cross section. Finally, the design and installation of the DiMES in-vessel components on DIII-D was completed.
