Low and declining soil fertility has been recognized for a long time as a major impediment to intensifying agriculture in sub-Saharan Africa (SSA). Consequently, from the inception of international agricultural research, centres operating in SSA have

A Computational/Spectroscopic Study of a Newly Derived General Unified Theory of Spectral Line Shapes to Measure HWHM's for an Ar-perturber/K-radiator system, Using Two 74sp← Transitions, as Applied to the Line Core
Autor: W. C. Kreye
Publikováno v: The Open Spectroscopy Journal. 7:1-8
In a recent publication, a new unified theory of spectral line shapes was derived, which allowed for the variation of the electric dipole moment with perturber positions. The present author put the () gs term derived from the theory into a computable

Theoretical estimation of the acidities of alcohols and azoles in gas phase, DMSO, and water
Autor: Paul G. Seybold, W. C. Kreye
Publikováno v: International Journal of Quantum Chemistry. 112:3769-3776
Most acidities and basicities of chemical compounds are measured in aqueous solution since this solvent is most important for biochemical and environmental applications, but the acidities of compounds in the gas phase and in other solvents can also b

Temperature Dependences of the Quantum-Mechanical and Semi-Classical Spectral-Line Widths and the Separation of the Impact and Non-Impact Regions for an Ar-Perturbed/K-Radiator System
Autor: W. C. Kreye
Publikováno v: International Journal of Spectroscopy. 2010:1-6
Quantum-mechanical and semi-classical spectral-line shapes are computed at 𝑇=400, 800, and 1000 K for the line core of the 5802 Å line of the Ar-Perturbed/K-Radiator system. HWHMs (𝑤's) are measured from computed full spectral-line shapes. The

Causes for soil sickness affecting early plant growth in aerobic rice
Autor: J.E. Faronilo, C. Kreye, L. Llorca, Bas A. M. Bouman
Publikováno v: Field Crops Research. 114:182-187
In aerobic rice, adapted varieties are grown in non-flooded and non-saturated soil. In the Philippines, occasional poor crop growth and yield failures have been reported. To investigate the underlying causes, we conducted 3 pot experiments using the

Correlations between quantum chemical indices and the pK a s of a diverse set of organic phenols
Autor: Paul G. Seybold, W. C. Kreye
Publikováno v: International Journal of Quantum Chemistry. 109:3679-3684
In earlier studies (Gross and Seybold, Int J Quantum Chem, 2001, 85,569; Gross et al., Int J Quantum Chem, 2002, 90, 445), it was shown that variations inseveral calculated quantum chemical charge and energy parameters were stronglycorrelated with th

Possible causes of yield failure in tropical aerobic rice
Autor: Bas A. M. Bouman, A. T. Lactaoen, J.E. Faronilo, Rubenito M. Lampayan, C. Kreye, A.R. Castañeda, L. Fernandez
Publikováno v: Field Crops Research. 111:197-206
Aerobic rice is a water-saving rice production system for water-short environments with favorable soils and adapted, potentially high-yielding varieties that are direct dry seeded. Soils remain aerobic but supplementary irrigation is applied as neces
