Optimization of grain sorghum water use efficiency under high frequency irrigation by system simulation and stochastic dynamic programming
(1962)
Water deficits reduce plant growth and subsequently, crop yields. Man has relied upon irrigation to overcome these crop water deficiencies. But since the present supplies of water are limited, more efficient irrigation ...
Creep in prestressed lightweight aggregate concrete
(1966)
This study was made to develop a criterion for predicting creep in prestressed lightweight-aggregate concrete beams and to investigate the influence of magnitude of prestress on creep in lightweight-aggregate concrete. ...
An investigation of collisions of automotive vehicles with break-away highway sign supports
(1966)
A series of six full-scale crash tests employing an automobile towed into a collision with one support of a two support highway roadside sign was conducted. Fixed base sign supports were struck in two of the tests, and ...
Capital intensity and the real wage: a critical evaluation of Hayek's Ricardo Effect
(1961)
As any topic in capital theory, the Ricardo Effect has remained controversial and misunderstood. The object of this thesis is a clear exposition and concise criticism of the Ricardo Effect. The scope of the thesis is limited ...
Deformation characteristics of granular materials subjected to rapid, repetitive loading
(1966)
The engineering behavior of soils and aggregates is a function of their basic properties and the environment to which they are subjected. In pavement design the effect of repeated loading is in important environmental ...
Studies of fundamental properties and mechanical behavior of selected synthetic aggregates
(1966)
Synthetic aggregates produced by firing clays and shales are being increasingly used in the construction of concrete and asphalt structures. The anomalistic behavior of this synthetic product requires an extensive study ...
