Response of the Heliothis virescens (F.) larvae to nitrogen fertilization and irrigation inputs in cotton
(1988)
When high inputs of nitrogen (N) fertilizer and irrigation are used in cotton production, variation in quantity and quality of the crop as food for insect herbivores can result. Field studies were conducted in 1983-85 to ...
Some problems in sequencing and scheduling utilizing branch and bound algorithms
(1988)
This dissertation deals with branch and bound algorithms which are applied to the two-machine flow-shop problem with sparse precedence constraints and the optimal sequencing and scheduling of multiple feedstocks in a batch ...
Effects of statically performed toe touch stretches on torque production of the hamstring and quadriceps muscle groups
(1988)
Stretching used as part of a warm up routine for later performance has become not only popular but also recommended by physical educators. Warm up stretches are thought to enhance performance and reduce the incidence of ...
The relationship of self-concept and self-direction to life satisfaction in elderly women
(1988)
The purpose of this study was to determine, if possible, what factors in the lives of women contributed to the quality of their life in old age. There is very little known about the older woman and her reality. The limited ...
Evaluation of temperature, force, and chip formation in orthogonal turning of leaded brass
(1988)
The primary purpose of this research was to investigate the role of lead inclusions in leaded brass or free-machining brass on chip temperatures, cutting force, feed force and deformed chip thickness. The experiment was ...
The establishment of criteria for standards of principal performance
(1988)
The purpose of this study was to define functions and roles the principal must fulfill as the educational leader and the contexts in which he fulfills them. Criteria for judging principal performance in terms of function ...
Optimal hedging with agricultural options in a portfolio context : information and efficiency
(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 ...
The feasibility of using industrial simulation software to teach complex manufacturing concepts / Winterberger
(1988)
An experiment was conducted to ascertain whether industrial simulation software could be used to teach complex manufacturing concepts to students in manufacturing technology programs. The objectives of the study were to ...
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 ...
