Effect of temperature on seed dormancy and alpha-amylase activity during kernel maturation and germination in wheat (Triticum aestivum L.) cultivars

Creator:: Reddy, Lekkala Vijayasimha
Abstract:: Effect of temperature on seed dormancy, alpha-amylase activity and kernel weight in five wheat (Triticum aestivum L.) varieties was studied. Three ripening temperature conditions - 15.5°C, 26.6 °C and "Field" were used to induce dormancy. Alpha-amylase activity and kernel weight of developing kernels was determined every ten days after anthesis...

Consolidation characteristics of calcareous deep sea-floor sediments from the Panama Basin

Creator:: Kao, Yeoung Ting
Abstract:: Calcareous sediments containing a large percentage of foraminiferal microskeletal tests were taken from sites in the Panama Basin and subjected to an investigation to determine the consolidation characteristics of this type of soil. The consolidation-stress curves and the time rate of consolidation curves in particular were investigated in this study....

An investigation of the feasibility of a cutbank slope design method based on the analysis of natural slopes

Creator:: Keener, Quentin Roosevelt
Abstract:: The failure of cutbanks is a major problem encountered by those who construct low-cost roads in naturally forested residual soils. Attempts have been made to lessen the severity of failures by classifying certain soil areas as to their susceptibility to failure, in addition to bringing past design experience into play...

Numerical method for calculating construction pore pressures in embankments

Creator:: Steward, John Erwin
Abstract:: A computer program was developed for estimating construction pore pressures in embankments without drainage at any location in the embankment at any time during construction. This program incorporated a modification of the Hilf-Brantz method of pore pressure calculation and a finite element method of stress computation. Previous methods of calculating...

Optimization of staged rankine energy conversion cycles for high efficiency

Creator:: Simmons, Larry Dean
Abstract:: Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

Bdellovibrio metabolism of host macromolecules

Creator:: Engelking, Henry Mark
Abstract:: The genus Bdellovibrio is characterized by the unique ability to parasitize and enter gram-negative host bacteria. This interaction leads to the consumption and death of the host cell as the Bdellovibrio grows and divides into progeny. Little is known about the metabolism of host cell components by Bdellovibrio. The possibility...

Investigation of a nonwoven fabric as a reinforcement for gravel paved roads

Creator:: Kelsay, Harry Stanley
Abstract:: Full scale test roads combined with a theoretical analysis were used to evaluate the benefits of incorporating a fabric as a base course support material for gravel paved roads. One material, a synthetic, nonwoven, polypropylene fabric was used in this investigation. This fabric was used on top of the subgrade...

A model study of fabric reinforced earth walls

Creator:: Stilley, Alan Neal
Abstract:: The concept of placing high strength linear reinforcements in a soil backfill to produce a vertical retaining structure is a recent idea that has been applied with success at a number of locations. Rational procedures have been developed for the design of these structures when the reinforcements consist of long...
