(1989)
The three-year pilot program initiated by the Commodity Futures Trading Commission (CFTC) in 1981 led to trading in options on agricultural futures on a number of commodities starting in late 1984 and early 1985. This ...
Evaluation of sorghum genotype mixtures in controlling sorghum leaf blight
(1989)
Field and greenhouse experiments were conducted to evaluate the effect of genotype mixtures on the development of sorghum leaf blight caused by Exserohilum turcicum. For the field experiments, three locations of Central ...
Growth, ion uptake, and some metabolic processes of Pistacia spp. affected by salinity and boron
(1989)
Rootstocks which restrict uptake of toxic elements, such as Na, Cl, and boron (B), may increase resistance of grafted trees to salt and B stresses. The objectives of this study were to evaluate i) growth, ion uptake, and ...
Three-dimensional numerical study of thunderstorm downdrafts and associated outflow boundaries
(1989)
Thunderstorm downdrafts and their associated outflow boundaries are numerically simulated using a high-resolution, time-dependent, three-dimensional model. The initial downdraft is initiated by specifying a distribution ...
Modification of soy protein using the plastein reaction, phosphorylation, and ethylation, and their effects on functionality
(1989)
Soy protein isolate was modified using enzymatic hydrolysis and the plastein reaction. Soy protein and plastein were each also chemically modified by phosphorylation and ethylation. Only 34% of the hydrolysate's nitrogen ...
Geotechnical properties of periplatform carbonate sediments
(1989)
Periplatform sediments from the slopes north of little Bahama Bank and Exuma Sound were studied extensively for use as a model for sediments in other similar environments within the upper 50 to 150 meters below the seafloor ...
Quality, composition, and starch properties of sorghum Tô, a thick porridge
(1989)
To is a thick porridge prepared by cooking a flour slurry in boiling water with continous stirring. The relationship between to texture and solubility properties with physicochemical characteristics of sorghum with different ...
The impact of conferencing with disruptive students and their teachers on disruptive classroom behaviors of fourth grade students
(1989)
This study was designed to determine whether disruptive behaviors can be reduced through a classroom support program of conferencing with disruptive fourth grade students and consulting with the teachers of the disruptive ...
Measurement of diffusion coefficients in the cyclohexane/toluene/polystyrene system using perturbation gas chromatography
(1989)
A semi-automated vibrating tube densimeter designed for operations between 100 and 700 K and to 70 MPa is described. This densimeter features continuous flow of the sample fluid and a fluid conditioning system that rapidly ...
Colonization and evaluation of selected exotic Hymenoptera parasites against the southwestern corn borer, (Lepidoptera: Pyralidae)
(1989)
Six exotic Hymemoptera parasite species were evaluated for parasitization of the southwestern corn border (SWCB), diatraea grandiosella Dyar (Lepidoptera: Pyralidae). Studies were conducted in the laboratory and in commercial ...
