Genetic Improvement of African Maize towards Drought Tolerance: A Review
(IISTE, 2016)
Africa supports a population of over 1 billion people with over half of them depending on maize for food and
feed either directly or indirectly. Maize in Africa is affected by many stresses, both biotic and abiotic ...
Extraction of Scene Text Information from Video
(Modern Education and Computer Science, 2016)
In this paper, we present an approach for scene text extraction from natural scene video frames. We assumed that the planar surface contains text information in the natural scene, based on this assumption, we detect planar ...
Effect of Climate Change on Small Scale Agricultural Production and Food Security in Kitui District, Kenya
(World Science and Research Publishing, 2014-10)
Most of the world’s arid and semi-arid lands (ASALs) are found in the
developing countries. These ASALs face many challenges some of which are as
a result of the declining availability of water resources and increasing ...
Localization of Overlaid Text Based on Noise Inconsistencies
(2015-04)
In this paper, we present a novel technique for localization of caption text in video frames based on noise inconsistencies. Text is artificially added to the video after it has been captured and as such does not form part ...
Combustion synthesis, characterization and luminescence properties of barium aluminate phosphor
(Elsevier, 2014-09)
The blue-green emitting Eu2+ and Nd3+ doped polycrystalline barium aluminate (BaAl2O4:Eu2+,Nd3+) phosphor, was prepared by a solution-combustion method at 500 °C without a post-annealing process. The characteristic variation ...
Mutation EthAW21R confers co-resistance to prothionamide and ethionamide in both Mycobacterium bovis BCG and Mycobacterium tuberculosis H37Rv
(Dove Press, 2018-06)
Ethionamide (ETA) and prothionamide (PRO) are interchangeably used in tuberculosis
(TB) chemotherapy regimens. Subtle discrepancies between biochemical and genetic
information on the modes of sensitivity and resistance ...
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)
In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ...
Effect of Ga3+ and Gd3+ ions substitution on the structural and optical properties of Ce3+-doped yttrium aluminium garnet phosphor nanopowders
(John Wiley & Sons, 2016-03)
ABSTRACT: The structural and optical properties of commercially obtained Y3Al5O12:Ce3+ phosphor were investigated by replacing
Al3+ with Ga3+ and Y3+ with Gd3+ in the Y3Al5O12:Ce3+ structure to form Y3(Al,Ga)5O12:Ce3+ and ...
The Aesthetic Function of the style of Masking as used In V.S. Naipaul’s Collection of Sketches, Miguel Street
(2016-06)
The study is based on the assumption that literary style is paramount to literary communication and the meaning we derive out of a work of literature. Literary meaning cannot therefore be divorced from literary style. The ...
Performance Evaluation of Proximal Sensors for Soil Assessment in Smallholder Farms in Embu County, Kenya
(MDPI, 2016)
Four proximal soil sensors were tested at four smallholder farms in Embu County, Kenya:
a portable X-ray fluorescence sensor (PXRF), a mobile phone application for soil color determination
by photography, a dual-depth ...
