Effect of subirrigation on the subsurface crop environment and crop production
(1971)
Subirrigation of summer squash using a fluctuating water table was conducted in 12 lysimeters containing undisturbed soil cores. The soil consisted of a 45-cm depth of sandy loam topsoil and a sandy clay subsoil. The study ...
Structure and conformation of Th(IV)-complexes of ethylenediaminetetraacetic acid and its analogs in aqueous solution
(1971)
The thorium(IV) complexes of ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaaceticacid (DTPA), triethylenetetraminehexaacIetic acid (TTHA) and N-hydroxyethylethylenetriaacetic acid (HEDTA) have been studied ...
Response of sorghum, millet and corn to different strains of sugarcane mosaic virus and strain A of maize dwarf mosaic virus
(1971)
A study was conducted to determine the response of sorghum, millet and corn to the strains A, B, D, H, and I of sugarcane mosaic virus (SCMV) and strain A of maize dwarf mosaic virus (MDMV) with respect to disease reactions ...
Numerical techniques for the analysis of digital radar data with applications to meteorology and hydrology
(1971)
Investigation has been conducted on the feasibility of utilizing digital radar data for "real-time" meteorological and hydrologic applications. Numerical techniques have been developed that enhance the usefulness of weather ...
The development of a procedure for estimating statewide air passenger travel demand
(1971)
This research is addressed to the development of a technique for estimating air passenger travel demands. Techniques previously used for estimating air passenger travel demands are applicable for planning at the national ...
Studies in naphthyridine chemistry
(1971)
Methyl naphthyridines and 5 out of the 6 possible parent naphthyridines were synthesized. A simple procedure for preparing 2, 7- and 4 -methyl-2,7-naphthyridine was developed. The nucleophilic substitution reactions of ...
Confidence regions for variance ratios in variance components model
(1971)
This study, using the method described by Hartley and Rao [10], derives confidence regions for the ratios of variances in random model. Each region is compared with a confidence region derived by Wald [22]. We derived ...
The crystal structure determinations of some halide complexes of antimony
(1971)
Bispiperidinium Sb(III)Br₅ (piperidine = [see PDF for diagram] forms orthorhombic crystals, P2₁2₁2₁, a = 18.415(3), b = 12.507(3), c = 8.851(2) Å at 22°C, Z = 4. The structure is isomorphous with its Bi(III) Br₅. analogue. ...
Dynamic simulatin of unsteady flow of water in unsaturated soils and its application to subirrigation system design
(1971)
Unsteady vertical flow of water in unsaturated soils was simulated utilizing S/360 CSMP (Continuous System Modeling Program), a recently developed language specially designed for digital simulation of transient phenomena ...
