An Introduction to Differential Geometry: The Theory of Surfaces
(Science Publishing Group, 2017)
From a mathematical perspective, a surface is a generalization of a plane which does not necessarily require being flat, that is, the curvature is not necessarily zero. Often, a surface is defined by equations that are ...
Species Composition, Distribution, and Seasonal Abundance of Liriomyza Leafminers (Diptera: Agromyzidae) Under Different Vegetable Production Systems and Agroecological Zones in Kenya
(Environmental Entomology, 2015-02-03)
A longitudinal study to identify the species of Liriomyza leafminer, their distribution, relative abundance, and seasonal variation, including their host range, was conducted in vegetable fields at three altitudes in Kenya ...
Interaction between Phaedrotoma scabriventris Nixon and Opius dissitus Muesebeck (Hymenoptera: Braconidae): endoparasitoids of Liriomyza leafminer
(African Entomology, 2015)
The exotic parasitoid, Phaedrotoma scabriventris Nixon, was imported from Peru for the
biological control of invasive Liriomyza species in vegetable and ornamental crops in Kenya where Opius dissitus Muesebeck is the most ...
Selection of promising fungal biological control agent of the western flower thrips Frankliniella occidentalis (Pergande)
(Letters of Applied Microbiology, 2012-02)
Aims: Larval stages of Frankliniella occidentalis are known to be refractory to fungal infection compared with the adult stage. The objective of this study was to identify promising fungal isolate(s) for the control of ...
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, ...
