A new furoquinoline alkaloid to which we have assigned the trivial name nobiline, and seven other quinonline alkaloids were isolated and identified from the leaves and fruits of Teclea nobilis, an African medicinal plant.

Macrotermes michae/seni, a dominant invertebrate herbivore in the semi-arid savanna of Kajiado, Kenya, was studied to establish what measures its foragers adopt to counteract ant predation while insuring adequate ...

The adaxial leaf temperatures of 3 cultivars of Phaseolus vulgaris and 1 cultivar of Tepary bean (Phaseolus acutifolius) were measured from 0600 to 1800 hours. 2 instruments having different measurement principles were ...

this study, rotated principal component analysis (RPCA) was used to study the spatial and temporal characteristics of asonal rainfall over East Africa during the period 1922-1983. The RPCA solutions were derived from both ...

ARIMA (p, d, q) models were fitted to areal annual rainfall of two homogeneous regions in East Africa with rainfall records extending between the period 1922-80. The areal estimates of the regional rainfall were derived ...

In this study, global sea surface temperature anomalies within ±300 latitudes of the equator were correlated with the time series of the major rotated principal component analysis (RPCA) modes of the seasonal rainfall ...

From the two-dimensional transonic small disturbance equation, with artificial viscosity, we derive an integro-differential equation and subsequently an integral equation. The computational domain is discretized into ...

Dendroaspis angusticeps venom (75 micrograms/ml) caused an irreversible blockade of the directly as well as directly evoked contractions of the rat hemidiaphragm and indirectly evoked contractions of the chick biventer ...

The statistical characteristics of wind power in Kenya were investigated in this study with the data consisting of daily maximum, minimum and mean wind speed values from 24 sites in Kenya. The method of Principal ...
