In Kenya, maize (Zea mays L.) is mainly grown on acid soils in high rainfall areas. These soils are known for
low available phosphorus (P), partly due to its sorption by aluminium (Al) and iron oxides. The study ...

Tea production in the Kenyan Ri Valley uses high rates of nitrogenous fertilizer. Nitrates can be discharged to water bodies
through leaching and surface run-off. Nitrate levels above 10 mg/L NO3−–N cause methemoglobinemia ...

Aluminium (Al) toxicity, phosphorus (P) deficiency and low rhizobia populations limit Sesbania
(Sesbania sesban) performance in tropical acid soils. The study determined the i) indigenous rhizobia
populations that nodulate ...

Land surveying has been a challenge for many years both in developed and developing countries.
For instance the triangular survey consumes a lot of time as several sides of the field need to be measured.
Solutions to ...

The aim of this study is to examine unsteady incompressible Magnetohy-
drodynamic fluid flow together with soret and dufour effects on mass and
heat transfer through a collapsible elastic tube. The governing equations ...
Mutua Samuel; S.S. Motsa(Applied Mathematics and Computation, 2019)
In this paper, we propose a new numerical method namely, the trivariate spectral collo-
cation method for solving two-dimensional nonlinear partial differential equations (PDEs)
arising from unsteady processes. The ...
Information Literacy (IL) skills are integral in today’s information society. Efforts and initiatives
put in place have a great impact on how Information Literacy skills are imparted to the targeted

Survival analysis models the time it takes until an event occurs.
The prototypical event is death, from which the name survival analysis
is derived.Accordingly, each time survival analysis is studied, aspects
of some ...
