Interpretation of small-modulation photocurrent transients in dye-sensitized solar cells – A film thickness study
(2010)
Electron transport in dye-sensitized solar cells with varying mesoporous TiO2 film thicknesses was investigated using experimental and computational methods. More specifically, photocurrent transients resulting from ...
Effects Of Plant Structure On Butterfly Diversity In Mt. Marsabit Forest, Northern Kenya
(2010)
Butterflies, like most forest dependent animals are good ecological indicators of the health of the forests they dwell. For example, butterfly species richness decreases after a forest disturbance and fragmentation but a ...
The Negative Binomial Parameter K As A Measure Of Dispersion
(University of Nairobi, 2010)
The role of the negative binomial parameter k and index of patchiness as measures of dispersion in relation to random removal of individuals are discussed. The aim of this paper is to demonstrate analytically that the ...
An exploratory survey of malaria prevalence and people's knowledge, attitudes and practices of mosquito larval source management for malaria control in western Kenya
(2010)
A large proportion of mosquito larval habitats in urban and rural communities in sub-Saharan Africa are man-made. Therefore, community-based larval source management (LSM) could make a significant contribution to malaria ...
l-Arginine supplementation in women with chronic hypertension: impact on blood pressure and maternal and neonatal complications
(2010)
Objective. To evaluate l-arginine (l-Arg) supplementation in pregnant women with chronic hypertension and its effects on blood pressure (BP) and maternal and neonatal complications.
Methods. We enrolled 80 women affected ...
The Application of the Method of Horace to Get Number of Generators for an Ideal of s General Points in P4
(2010)
Let S be a general set of s points in P4, and R the homogeneous coordinate ring
of P4. Then the ideal of S, IS has a minimal free resolution of the form:
0 −−−→ F3 −−−→ F2 −−−→ F1 −−−→ F0 −−−→ IS −−−→ 0
where Fp = R(−d ...
Magnetic properties of iron nanoparticle
(University of Nairobi, 2010)
Magnetic properties of Fe nanoparticles with different sizes synthesized by a physical deposition technique have been investigated experimentally. We have used a high pressure sputtering technique to deposit iron nanoparticles ...
The Sensitivity of East African rift lakes to climate fluctuations
(2010)
Sequences of paleo-shorelines and the deposits of rift lakes are used to reconstruct past climate changes in East Africa. These recorders of hydrological changes in the Rift Valley indicate extreme lake-level variations ...
On the effects of random forces in non uniformly distributed dynamical system
(University of Nairobi, 2010)
Interaction of a dynamical system with stochastic source R(t) is studied using parabolic type equation on a circle of length 2L.Greens function for the system is constructed and it is shown that almost all the correlation ...
