Texas Register, Volume 4, Number 56, Pages 2607-2634, July 27, 1979

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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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

Preliminary designs for ocean thermal energy conversion (OTEC) stationkeeping subsystems (SKSS). Task II. Conceptual design. Final report (open access)

Preliminary designs for ocean thermal energy conversion (OTEC) stationkeeping subsystems (SKSS). Task II. Conceptual design. Final report

The study is presented in five sections: design loads, conceptual designs, trade studies, cost analysis and concept evaluation and ranking. Extensive appendixes provide back up calculations and data to support the results. Environmental forces and yaw moments acting on the barge and spar in the various design sea states are presented including wave, wind and current effects. A parametric analysis illustrates the impact on holding power requirement of varying the return periods for operational and extreme sea state. The conceptual designs are presented for the barge followed by those for the spar, including configuration definition, performance characteristics, interfaces, areas for development, and deployment scenarios for selected concepts. The concept definition is followed by a set of trade studies that were performed to evaluate candidate anchor types and anchor leg materials. Parametric variations in anchor leg characteristics, wire-rope-to-chain length ratio for example, illustrate the influence of the significant design parameters on performance. An extensive cost analysis of the candidate SKSS concepts is presented, including cost estimates, life cycle cost scenarios leading to expected value of life cycle cost, and cost equivalence of operational failures. An evaluation of the eight SKSS concepts is presented, including assessment of performance and rankings based on …

Computer programs in BASIC language for graphite furnace atomic absorption using the method of additions. Part 1. Operating instructions (open access)

Computer programs in BASIC language for graphite furnace atomic absorption using the method of additions. Part 1. Operating instructions

These instructions describe how to use BASIC language programs to process data from atomic absorption spectrophotometers using the graphite furnace and the method of additions calibration technique. The instructions cover loading the programs, responding to computer prompts, choosing among various options for processing the data, performing operations with an automatic sampler, and producing reports. How the programs interact with each other is also explained. Examples of computer/operator dialogue are presented for typical cases. In addition, a concise set of operating instructions is included as an appendix.

Hydrogeochemical and stream sediment reconnaissance basic data for Hutchinson NTMS Quadrangle, Kansas (open access)

Hydrogeochemical and stream sediment reconnaissance basic data for Hutchinson NTMS Quadrangle, Kansas

Results of a reconnaissance geochemical survey of the Hutchinson Quadrangle, Kansas are reported. Field and laboratory data are presented for 592 groundwater and 616 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. The groundwater data indicate that the southwestern corner of the quadrangle offers some potential for uranium mineralization. Five large clusters of groundwaters with high uranium values occur here. Wells in the southwestern corner produce waters from the Permian Nippewalla Group and the overlying Kiowa Shale that often contain high concentrations of arsenic, molybdenum, selenium, and vanadium which are known to associate with uranium in sandstone deposits. The stream sediment data indicate that most of the uranium and thorium anomalies occur as placer-type concentrations associated with Quaternary deposits. There are three areas that show groups of high uranium and thorium concentrations in the stream sediments; one in the northeast in Chase, Lyon, Morris, and Wabaunsee Counties; one in Dickinson and Geary Counties; and the third, the large area west of long. 97/sup 0/ …

Method of inspecting Raschig rings by neutron absorption counting (open access)

Method of inspecting Raschig rings by neutron absorption counting

A neutron counting method for inspecting borosilicate glass Raschig rings and an apparatus designed specifically for this method are discussed. The neutron count ratios for rings of a given thickness show a linear correlation to the boron oxide content of the rings. The count ratio also has a linear relationship to the thickness of rings of a given boron oxide content. Consequently, the experimentally-determined count ratio and physically-measured thickness of Raschig rings can be used to statistically predict their boron oxide content and determine whether or not they meet quality control acceptance criteria.

Failure analysis of a Hastelloy C-276 geothermal injection pump shaft (open access)

Failure analysis of a Hastelloy C-276 geothermal injection pump shaft

A metallurgical analysis of a fractured Hastelloy C-276 brine injection pump shaft was carried out to determine the cause of failure. Loss of load carrying cross section due to intergranular corrosion by molten bronze bearing alloy followed by torsional overload of the remaining section was the cause of failure. Lack of evidence for brine induced corrosion or stress corrosion of the Hastelloy C-276 alloy is consistent with prior successful experience with this material in contact with high temperature, high salinity Salton Sea Geothermal Field brines.
