We have made a detailed study of the care that must be taken to correctly measure OH radical concentrations in flames. A large part of these studies has concerned collisional quenching of hydride radical species (OH, NH, and NH{sub 2}), in particular the dependence upon rotational level and collision velocity (temperature). The results on OH and NH have shown unique and interesting behavior from the viewpoint of fundamental molecular dynamics, pointing to quenching often governed by collisions on an anisotropic, attractive surface, whereas NH{sub 2} quenching appears to depend on state-mixing considerations, not dynamic control. This state-specific behavior of these small, theoretically tractable hydrides has direct ramifications for quantitative flame diagnostics. Our other effort in the diagnostic area has been repeated but unsuccessful searches for laser induced fluorescence in the vinyl radical.

Research programs from the National Institute for Petroleum and Energy Research (NIPER) are briefly described. Topics include enhanced recovery, studies on reservoir rock, microbial EOR, development of analytical techniques for petroleum analysis, and imaging techniques applied to fluids study in porous media.

During the 1988--89 Tevatron Collider run the CDF detector has collected data for an integrated luminosity of 4.4 pb{sup {minus}1}. The sample has been used to search for the top quark in several topologies. Preliminary results show that a top mass below 89 GeV is excluded at the 95% confidence level, thus extending the limit of 77 GeV previously published by CDF. 14 refs., 8 figs.

Acceptance criteria for uranium check standards used to verify fluorimeter calibration have been developed. This work was done in response to Tiger Team finding QA/BMP-5, item 4. Data used as input to these calculations is retained in the Tiger Team closeout file, located in the Technical Service Division managers office. 3 refs., 4 tabs.

Despite the rise in petroleum products prices, a colder-than-normal winter in the latter part of 1989 spurred an increase in demand for distillate fuel oils. The shipping and electric utilities industries contributed to a significant rise in demand for both distillate and residual fuels oils in 1989. A total of 72.9 billion gallons of fuel oil and kerosene were sold to consumers in 1989, an increase of 3.0 percent over 1988 sales volumes. Of all fuel oil sold during 1989, distillate fuel oil accounted for 68.3 percent, which was an increase over 1988 when distillate fuel oil accounted for 67.2 percent of all fuel oil products sold in the United States. Residual fuel oil's share of total fuel oil sold fell slightly to 29.9 percent from 30.7 percent in 1988. Kerosene followed with a 1.8 percent share, also falling from the previous year when it accounted for a 2.1 percent share of total fuel oil sold. 3 figs., 24 tabs.

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.

This invention relates to a regenerable activated bauxite adsorber alkali monitor probe for field applications to provide reliable measurement of alkali-vapor 5 concentration in combustion gas with special emphasis on pressurized fluidized-bed combustion (PFBC) off-gas. More particularly, the invention relates to the development of a easily regenerable bauxite adsorbent for use in a method to accurately determine the alkali-vapor content of PFBC 10 exhaust gases.

The Peer Review Panel was charged with deciding whether seismic methods, which had been utilized at Yucca Mountain with mixed results in the past, could provide useful information about the Tertiary structure in the Yucca Mountain area. The objectives of using seismic methods at Yucca Mountain are to: (a) obtain information about the structural character of the Paleozoic-Tertiary (Pz-T) contact, and (b) obtain information about the structural and volcanic details within the Tertiary and Quaternary section. The Panel recommends that a four part program be undertaken to test the utility of seismic reflection data for characterizing the structural setting of the Yucca Mountain area. The Panel feels strongly that all four parts of the program must be completed in order to provide the highest probability of success. The four parts of the program are: (a) drill or extend a deep hole in Crater Flat to provide depth control and allow for the identification of seismic reflectors in an area where good quality seismic reflection data are expected; (b) undertake a full seismic noise test in Crater Flat, test 2D receiver arrays as well as linear arrays; perform an expanding spread test using both P and S wave sources to obtain …
