Coccoliths from the Cretaceous-Tertiary boundary of the Walvis Ridge, South Atlantic : biostratigraphic and paleoecological implications
(1989)
Biostratigraphy, diversity, and oxygen and carbon isotopes are determined for calcareous nannoplankton from four sections of Cretaceous-Tertiary boundary interval sediments on Walvis Ridge in the South Atlantic (DSDP Sites ...
Studies on the transport and storage of indole alkaloids by Catharanthus roseus
(1988)
The transport and storage of indole alkaloids by mesophyll protoplasts of Catharanthus roseus (L.) G. Don was characterized. Uptake of alkaloids by mesophyll protoplasts was found to have two components: a rapid, non-specific ...
A characterization of sorghum (Sorghum bicolor (L.) Moench) for biomass utilization
(1984)
Increased utilization of novel biomass sources for energy conversion schemes has become a significant portion of energy related research and sorghum (Sorghum bicolor (L.) Moench) is often considered a viable potential ...
Mechanical covering to prevent shoulder greening in white onions
(1989)
Onion (Allium cepa L.) varieties 'Contessa', 'White Early Supreme', 'Texas Grano 1015Y' (TG 1015Y), and 'Perla' were utilized in field studies that were conducted in 1988 and 1989 in Rio Grande City, College Station, Weslaco ...
Characterization of active sites and the effect of reduction and metal promoters on iron catalysts
(1989)
Infrared spectroscopy has been used as the principal method of characterizing the adsorption sites of iron-based catalysts. Nitric oxide and carbon monoxide were used as probe molecules to observe the effects of reduction ...
Boundary kernel estimation of the two sample comparison density function
(1989)
The focus of this work is to derive functional and graphical statistical techniques for the two sample problem suitable for implementation in modern computing environments. In the two sample problem, it is desired to test ...
Improved techniques for reliability evaluation of generation systems
(1989)
This dissertation represents new techniques for evaluating generation capacity reliability. These techniques are based on Fourier transforms and their properties. They permit the use of continuous probability distribution(s) ...
A screening technique for detecting levels of resistance in cucumber (Cucumis sativus L.) to belly rot induced by Rhizoctonia solani Kuehn
(1988)
A procedure for detecting cucumber fruit resistance to belly rot induced by Rhizoctonia solani is described. Inoculum in an unsterilized soil, naturally infested with Rhizoctonia solani Kuehn, AG-4, was increased by placing ...
The inverse tsunami problem of an island
(1989)
To date there exists no deep water record of a major tsunami from a benthic pressure gauge. Such deep water records and their spectra are desirable as a means of characterizing the tsunami source. The closest thing to such ...
Hormonal basis for developmental arrest of last-instar Heliothis virescens larvae by Campoletis sonorensis polydnavirus
(1987)
Campoletis sonorensis is an ichneumonid endoparasitoid of Heliothis virescens larvae. The polydnavirus which occurs in the reproductive tract of C. sonorensis (CsV) has several effects on the host independent of the presence ...
