During the first year of the grant, we participated in three WOCE expeditions (a total of 152 days at sea) in the South Pacific Ocean, and the field phase of the proposed investigation has been successfully completed. The total CO[sub 2] concentration and pCO[sub 2] were determined at sea in 4419 water samples collected at 422 stations. On the basis of the shipboard analyses of SIO Reference Solutions for CO, and a comparison with the results of previous expeditions, the overall precision of our total CO[sub 2] determinations is estimated to be about [plus minus]2 uM/kg. The deep water data indicate that there is a CO[sub 2] maximum centered about 2600 meters deep. This appears to represent a southward return flow from the North Pacific. The magnitude and distribution of the CO, maximum observed along the 135.0[degrees]W meridian differ from those observed along the 150.5[degrees]W meridian due to Tuamotu Archipelago, a topographic high which interferes with the southward return flow. The surface water pCO[sub 2] data indicate that the South Pacific sub-tropical gyre water located between about 15[degrees]S and 50[degrees]S is a sink for atmospheric CO[sub 2].

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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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.

A new technique is describe for the direct detection of volatile organic compounds in aqueous solutions at levels in the parts per trillion range. The sample is enriched in analyte in two consecutive stages, one utilizes a semi-permeable membrane interface and the other a jet separator. The analyte solution is sampled as it flows coaxially over a semi-permeable capillary membrane, the interior of which is continuously purged by helium. The permeate is pneumatically transported to the mass spectrometer via a jet separator, which is used to remove excess helium and water from the analyte vapor stream. Data are reported for an ion trap mass spectrometer used in conjunction with a conventional fixed-gap quartz jet separator. Typical analyte response times are 2-5 minutes and flow injection methods are used for sample delivery. Detection limits in the range 30 to parts per billion are observed for selected volatile organic compounds and the response is linear over 3 orders of magnitude. Details of the construction of the interface are provided.

Letter opinion 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, Dan Morales, regarding a legal question submitted for clarification; Whether a municipality generally must comply with subchapter C of chapter 395 (sections 395.041 through 395.058) of the Local Government Code before enacting or imposing a water tap fee to pay for the installation of a water line to serve new development (ID# 19594)

The code POISSON is used to determine the longitudinal extent of the good field region of the cluster klystron solenoid. The field shape as a function of end-coil current enhancements is determined.

This eleventh edition of the Annual Energy Review (AER) presents the Energy Information Administration`s historical energy statistics. For most series, statistics are given for every year from 1949 through 1992. Because coverage spans four decades, the statistics in this report are well-suited to tong-term trend analyses. The AER is comprehensive. It covers all major energy activities, including consumption, production, trade, stocks, and prices, all major energy commodities, including fossil fuels and electricity. The AER also presents statistics on some renewable energy sources. For the most part, fuel-specific data are expressed in physical units such as barrels, cubic feet, and short tons. The integrated summary data in Section 1 are expressed in Btu. The Btu values are calculated using the conversion factors in Appendix A. Statistics expressed in Btu are valuable in that they allow for comparisons among different fuels and for the calculation of in the integrated summary statistics such as US consumption of Energy. The AER emphasizes domestic energy statistics.

The Department of Defense is sponsoring development of a centralized, integrated database, which will be a repository international surface cargo movement data. Scheduled for implementation surface in early 1994, the system will include a relational database management system, processing modules, and complex communication components. Four geographically separated sites are involved with development. Design and development of a major computer system is never simple, but when design and development occur at multiple sites, the problems are compounded, especially when the timeframe for project completion is extremely tight. Issues such as identical developmental platforms and communications strategies must be addressed. A design plan must be strictly followed to ensure consistency and to coordinate integration of modules developed at different sites.

For the four coals employed in this work, it was not possible to effectively grind the minus 50 mesh feed even at the lowest solids concentration range tried. The reason for this is the low feed rate which makes it impossible to obtain a uniform flow as the coarse particles in the feed tend to settle down and form sediment in either the tubing system or the grinding chamber. Besides, only moderate levels of solids concentration could be employed as high solids concentration are also fraught with sedimentation problem. Attempts to increase the flow rate resulted in the grinding media being taken out of the mill together with the slurry. As a result of these limitations posed by the instrument, further tests were restricted to using minus 100 mesh feed size and moderate levels of feed rate and Pulp density. Some of the results obtained are given in Tables I - 4 for the different coals used. It can be seen from the tables that the softest coal (Pocahontas No. 3 in this case) requires about 2 or 3 passes in order to obtain very fine product while the harder coals would require 4 or more passes. The number of …
