Enzymes in organic synthesis : uses of CMP-sialic acid synthetase, sialic acid aldolase and subtilisin
(1992)
Two of the key enzymes in the biosynthetic pathway of sialic acids were studied. A highly expressed CMP-sialic acid synthetase with a decapeptide tag attached at the C-terminal of the enzyme and the wild type enzyme from ...
Timing analysis of VLSI circuits using symbolic and visualization technics for practical applications
(1992)
In this dissertation, we apply the linear RC delay modeling techniques to empirically model the timing delay in the CMOS VLSI circuits. The multi-dimensional function of various circuit combinations and device parameters ...
Extrapolation of point data for resource mapping
(1992)
Since the early seventies, the usefulness of satellite imagery for producing vegetation maps has been well known. Even small scale imagery such as advanced very high resolution radiometer (AVHRR) has been applied to ...
Attitudes toward agriculture of minority and non-minority students enrolled in an introductory agriscience course in Texas
(1992)
The purposes of this study were to measure attitudes toward agriculture of minority and non-minority students who were enrolled in an introductory agriscience course in Texas and to identify factors influencing minority ...
The carbonic acid system and solubility of calcium carbonate and sulfate in aqueous solutions over a wide range of solution composition, temperature and pressure
(1992)
The stoichiometric Henry's law constant and dissociation constants for the carbonic acid system were experimentally determined in various aqueous solutions from 0 to 90°C to high ionic strengths by the solubility method ...
Overexpression, purification, and characterization of the Pseudomonas denitrificans and Salmonella typhimurium gene products in vitamin B12 biosynthesis, structural analysis of vitamin B12 intermediates, and enzymatic synthesis of factor S3
(1992)
Some of the Pseudomonas denitrificans cob and the Salmonella typhimurium cbi genes involved in vitamin B12 biosynthesis were overexpressed in the heterologous E. coli system and purified. The functions of P. denitrificans ...
Development and application of a prompt gamma activation analysis system in the measurement of neutron capture cross-sections of geologic materials
(1992)
A prompt gamma activation analysis system was developed using available equipment at the Texas A&M Nuclear Science Center. This system was used to obtain prompt gamma spectra from geologic materials. A series of exposures ...
An intelligent resource allocation system
(1992)
The main objectives of this research are investigating the process planning knowledge of allocating construction resources for earthmoving processes and capturing this knowledge in an Intelligent Resource Allocation System ...
Robust tree coding combined with harmonic scaling of speech
(1992)
Efficient speech coders using tree coding combined with harmonic scaling are designed at the rates of 6.4 kilobits/sec (kbps) and 4.8 kbps. A time domain harmonic scaling algorithm (TDHS) is used to compress input speech ...
Body composition, dietary intake, and energy expenditure in pregnant women
(1992)
Normal weight (NW) and overweight (OW) pregnant women were compared longitudinally regarding weight gain, pregnancy outcome variables, body composition, energy intake, and activity patterns. Subjects were measured during ...
