Encroachment of open grasslands and Acacia drepanolobium Harms ex B.Y.Sjöstedt habitats by Euclea divinorum Hiern in Ol Pejeta Conservancy, Kenya
(African Journal of Ecology , Wiley online Library, 2013-03)
Euclea divinorum, a fast establishing, unpalatable, and fire resistant bush is considered an invasive species in some parts of its range. In Ol Pejeta Conservancy (OPC), Kenya, E. divinorum bushes cover ˜27% of the total ...
Prevalence of intestinal parasitic infections in certified food-handlers working in food establishments in the City of Nairobi, Kenya
(Journal of Biomedical Research, 2012-03)
Most intestinal parasites are cosmopolitan with the highest prevalence in the tropics and subtopics. Rural-to-urban migration rapidly increases the number of food eating places in towns and their environs. Some of these ...
Compatibility of Metarhizium anisopliae isolate ICIPE 69 with agrochemicals used in French bean production
(Journal of Pest Management, 2012-04)
The compatibility of the Metarhizium anisopliae (Metschnikoff) Sorokin isolate ICIPE 69, which is being developed as a biopesticide for the control of Frankliniella occidentalis Pergande, was assessed under laboratory ...
Independent Measurement of θ13 via Neutron Capture on Hydrogen at Daya Bay
(Physical Review, 2014)
A new measurement of the θ13 mixing angle has been obtained at the Daya Bay Reactor Neutrino Experiment via the detection of inverse beta decays tagged by neutron capture on hydrogen. The antineutrino events for hydrogen ...
Evaluation of permutite for removal of radiocobalt from nuclear wastewater
(Journal of Radioanal Nucl Chem, 2014-07)
A synthetic zeolite, commercially available as permutite was tested for removing radiocobalt from aque- ous solutions by sorption. The sorption process was studied as a function of contact time, pH, ionic strength and solid ...
Investigation of photoneutron and capture gamma-ray production in Pb and W under irradiation from 16N decay radiation
(Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms; Elsevier, 2015-09)
Lead and tungsten are potential alternative materials for shielding reactor ex-core components with high 16N activity when available space limits application of concrete. Since the two materials are vulnerable to photonuclear ...
Evaluation of candidate materials for SCWR turbine and balance of plant shielding
(Progress in Nuclear Energy; ScienceDirect, 2015-03)
Since the coolant leaving the SCWR core contains an assortment of radioisotopes, it is necessary to identify appropriate materials for shielding ex-core components. Photon attenuation characteristics, photo-neutron production ...
Evidence for Potential of Managing Some African Fruit Fly Species (Diptera: Tephritidae) Using the Mango Fruit Fly Host-Marking Pheromone
(JOURNAL OF ECONOMIC ENTOMOLOGY, 2012-12)
We investigated conspecific and heterospecific oviposition host discrimination among four economically important fruit fly pests of mango in Africa (Ceratitis capitata, Wiedemann; C. fasciventris, Bezzi; C. rosa, Karsch, ...
The monotypic genus Bulborrhizina belongs to Bulbothrix sensu lato (Parmeliaceae, Ascomycota)
(The American Bryological and Lichenological Society, Inc. - The Bryologist, 2015)
The phylogenetic position of the monotypic genus Bulborrhizina is studied using molecular data from three loci (mtSSU, nuLSU and ITS) aligned with sequences from 95 other samples of parmelioid lichens. Bulborrhizina africana ...
Simulation of (16)O (n, p) (16)N reaction rate and nitrogen-16 inventory in a high performance light water reactor with one pass core
(Applied Radiation and Isotopes; Elsevier, 2014-12)
The rate of activation of the isotope (16)O to (16)N in a typical HPLWR one pass concept was calculated using MCNP code. A mathematical model was used to track the inventory of the radioisotope (16)N in a unit mass of ...
