Approaches for Testing Uniformity Hypothesis in Angular Data of Mega-Herbivores
(2016-03)
Circularstatistics is an area not used verymuch by ecologists to describe animal movement patterns.Nevertheless,the
connection betweenthe evaluation of temporalrecurring events and theanalysis of directional data haveconverged ...
Isolation and characterization of some gut microbial symbionts from fungus-cultivating termites (Macrotermes and Odontotermes spp.)
(Academic Journals, 2016-07)
Microbiota of termites is crucial for nitrogen cycle activities and degradation of recalcitrant components of plant biomass that influence soil structure and carbon mineralization in tropical and subtropical regions. The ...
Effect of Ga3+ and Gd3+ ions substitution on the structural and optical properties of Ce3+-doped yttrium aluminium garnet phosphor nanopowders
(John Wiley & Sons, 2016-01)
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 ...
Spatial Modelling and Mapping of Socio-Demographic Determinants of Infant Mortality in Kenya
(2016-03)
This paper addresses the problem of monitoring the infant and child mortality from point referenced data. Indicators of the determinants of child survival based on Mosley and Chen framework are derived and used to model ...

Properties of blue emitting CaAl2O4:Eu2+, Nd3+ phosphor by optimizing the amount of flux and fuel
(Elsevier, 2014-04)
Long afterglow CaAl2O4:0.03Eu2+, 0.03Nd3+ phosphor was prepared by solution-combustion synthesis. The active role of boric acid (H3BO3) as a flux in enhancing the Eu2+ photoluminescence and the effect of a varied amount ...
Effects of pea aphid secondary endosymbionts on aphid resistance and development of the aphid parasitoid Aphidius ervi: a correlative study
(2010-05)
In order to reduce parasite-induced mortality, hosts may be involved in mutualistic interactions in
which the partner contributes to resistance against the parasite. The pea aphid, Acyrthosiphon pisum
Harris (Hemiptera: ...
Temporal genetic structuring of a specialist parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae) attacking a specialist aphid on tansy
(The Linnean Society of London, 2011)
In insect species characterized by inbreeding, limited dispersal, and a metapopulation structure, high genetic
differentiation and reduced genetic diversity within local populations are expected. Using the model ...
Genotype variant of soybean cultivars around Lake Victoria region, East Africa
(2010-01)
Glycine gracilis, which originated from North-East China, is morphologically intermediate between the cultivated G. max and the wild form, G. soja. These three forms are cross-compatible and their crosses provide a resource ...
Application Of Multiple Circular-Linear Regression Models To Animal Movement Data With Covariates
(2016-04)
In a many biological and physical sciences studies, a set of techniques have been developed to analyse the relationship between the circular and linear data derived from the geographical positioning system (GPS) telemetry ...
