Land cover and use changes in the rangelands of Central-Uganda: Impacts on soil quality and pasture productivit
(University of Nairobi,, 2010)
This study determined the patterns and magnitudes of land cover
and use changes, their driving factors and impacts on soil quality
and pasture productivity in Nakasongola district. Satellite data
(1970 - 2009), surveys, ...
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 ...

Amongst the challenges faced by smallholder farmers
in production is inaccessibility to credit. This s
tudy sought to

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 ...
Angle resolved photoemission study of surface states on the Pt(997) vicinal surface
(University of Nairobi, 2010)
One-dimensional atomic chains can be synthesized on stepped surfaces and the electronic structure of the high vicinal surface plays an essential role in determining the physical properties of atomic chains grown on top of ...

(University of Nairobi, 2010)
Exserohilum turcicum the causal agent of northern corn leaf blight is a threat to corn production in many areas of the world. The pathogen has a high genetic variability in terms of virulence, genetic structure and several ...
Upper limits for undetected trace species in the stratosphere of Titan
(University of Nairobi, 2010)
In this paper we describe the first quantitative search for several molecules in Titan's stratosphere in Cassini CIRS infrared spectra. These are: ammonia (NH3), methanol (CH3OH), formaldehyde (H2CO), and acetonitrile ...
Life history context of reproductive aging in a wild primate model
(2010)
The pace of reproductive aging has been of considerable interest, especially in regard to the long postreproductive period in modern women. Here we use data for both sexes from a 37-year longitudinal study of a wild baboon ...
