Histological observations on the changes in thyroid activity in the scincid lizard, Mabuya striata, during different phases of tail regeneration
(Zoological Society of Southern Africa, 1977)
Measurements of the follicle cells of the thyroid during different phases of regeneration of the tail in the scincid lizard. Mabuya striata. indicate a decrease in thyroid activity during the wound-healing phase and an ...
Some effects of mound-building termites on soils in Uganda
(Bioinfo Publications, 1976-09)
Most large mounds in Uganda are built by termites of the genus Macrotermes. Except for those in valley bottoms they are composed of subsoil which is thought to be collected mainly from depths of 0.5 to 1.0 m, although the ...
Land, labour and capital in Natal: The Natal Land and Colonisation Company 1860–19481
(Cambridge University Press, 1975-04)
The history of the London-based Natal Land and Colonisation Company is explored against the background of the evolving political economy of rural Natal. In the early years of the colony, white-controlled farming operations ...
Changes in Fish Species Composition in Lake Naivasha, Kenya
(Kluwer Academic Publishers, 1979)
The fish species composition in Lake Naivasha has been modified during recent years. Out of seven introduced and one indigenous species reported in 1962, only three introduced ones are found today. The elimination of species ...
Reproductive Biology of Tilapia zillii (Gervais) in Lake Naivasha, Kenya
(Kluwer Academic Publishers, 1979)
Tilapia zillii breeds all year round in the equatorial Lake Naivasha with slightly high breeding intensity during wet months (March, May and July–August). A sex ratio of 1 : 1.28 was found between males and females. The ...
Emergence of Advance Waves in a Steady-state Universe
(Kluwer Academic Publishers, 1979)
In standard Wheeler-Feynman electrodynamics advanced waves from any source are absolutely canceled by the advanced waves from the absorber responding to that source. The present work shows this cancellation fails over ...
Reaction of some arylacetic acids and related compounds with alkaline sodium hypochlorite solution
(Royal Society of Chemistry, 1978)
The Structure and Synthesis of Barakol: a Novel Dioxaphenalene Derivative from Cassia siamea
(Royal Society of Chemistry, 1970)
Barakol, from the leaves of Cassia siamea, is shown to be a novel dioxaphenalene derivative. A synthesis from 3,5-dihydroxyphenylacetic acid is described.
Correlation of melting temperature and cesium chloride buoyant density of bacterial deoxyribonucleic acid.
(American Society for Microbiology, 1970)
Samples of bacterial deoxyribonucleic acid from bacteria having guanine plus cytosine (GC) contents in the range of 27 to 72 moles per cent GC were analyzed by optical melting (T(m)) and equilibrium buoyant density methods. ...
The method of the false transient for the solution of coupled elliptic equations
(Elsevier, 1973-08-04)
A method for the numerical solution of a system of coupled, nonlinear elliptic partial differential equations is described, and the application of the method to the equations governing steady, laminar natural convection ...
