(University of Nairobi, 2023)This study has been done using the first-principles technique based on the plane wave self-consistent field method as implemented in the quantum espresso computational code. The GGA has been used as the exchange-correlation ... -
Nighttime identification of region currents from Champ satellite observations over Equatorial Africa
(University of NairobiSchool of Physical Sciences, 2011)This dissertation investigates the ionospheric F-region currents inferred from the interpretation of the magnetic signatures using Challenging Minisatellite Payload (CHAMP) satellite data. The observations are limited ... -
Nitrogen fixation associated with maize plants (zea mays l.) in a temperate and a tropical soil
(Department of Botany, College of Biological and Physical Sciences, 1987)In the temperate soil, low rates of acetylene reduction activity were detected in excised roots of field grown maize without preincubation. A higher acetylene reduction activity (20 nmol C2H4/ g d.wt./ 24 h) was recorded ... -
