Cashew Volatiles Mediate Short-Range Location Responses in Pseudotheraptus wayi (Heteroptera: Coreidae)
(2013)
Pseudotheraptus wayi Brown (Heteroptera: Coreidae) is a major pest of cashew in East
Africa, but little is known about its chemical ecology. Here, we show by using behavioral assays and
chemical analysis that some ...
Indigenous Knowledge of Climatic Conditions for Sustainable Crop Production under Resource-Poor Farming Conditions Using Participatory Techniques
(University of Nairobi, 2013)
Rambuda irrigation scheme is situated in Vhembe District of Limpopo Province in South Africa. It was
established in 1952 and farmers do not have access to recorded climatic information. Farmers are growing crops
on a ...
Computational Modeling of the Triplet Metal-to-Ligand Charge-Transfer Excited-State Structures of Mono-Bipyridine–Ruthenium(II) Complexes and Comparisons to their 77 K Emission Band Shapes
(2013)
A computational approach for calculating the distortions in the lowest energy triplet metal to ligand charge-transfer (3MLCT = T0) excited states of ruthenium(II)–bipyridine (Ru–bpy) complexes is used to account for the ...
Limitations to Use of Infrared Spectroscopy for Rapid Determination of Carbon-Nitrogen and Wood Density for Tropical Species
(University of Nairobi, 2013)
Infrared (IR) spectroscopy was used as a rapid and non-destructive method to determine, carbon (C), nitrogen (N) and tree wood density.A total of 82 sample cores were scanned in the reflectance mode from 4000 to 400 cm-1 ...
Anthraquinones of the roots of Pentas micrantha
(2013)
Pentas micrantha is used in the East African indigenous medicine to treat malaria. In the first investigation of this plant, the crude methanol root extract showed moderate antiplasmodial activity against the W2- (3.37 ...
Taxis assays measure directional movement of mosquitoes to olfactory cues
(2013)
Background
Malaria control methods targeting indoor-biting mosquitoes have limited impact on vectors that feed and rest outdoors. Exploiting mosquito olfactory behaviour to reduce blood-feeding outdoors might be a ...
