Promising tree species as hedgerows for alley cropping in different environments in Haiti
(2019-05-03)
Alley cropping is a system whereby annual crops are planted between rows of trees, which are pruned during the cropping season and the prunings applied as mulch or green manure. During periods where no crop is grown, the ...

(2015-09-08)
This article describes a project to promote an approval plan for purchasing award-winning juvenile books. The overall project utilizes a combination of projects for promoting awareness and use of the awards books and the ...
Propagation of Electromagnetic Ion Cyclotron Waves in a Dipole Magnetic Field: A 2-D Hybrid Simulation
(2022-11-08)
Electromagnetic ion cyclotron (EMIC) waves are one commonly observed plasma waves in the Earth's inner magnetosphere and play a crucial role in particle dynamics in the radiation belt and ring current. EMIC waves are excited ...
Propagule size and sex ratio influence colonisation dynamics after introduction of a non-native lizard
(2022-01-28)
1. The composition of founding populations plays an important role in colonisation dynamics and can influence population growth during early stages of biological invasion. Specifically, founding populations with small ...

Proton velocity ring-driven instabilities and their dependence on the ring speed: Linear theory
(2022-10-12)
Linear dispersion theory is used to study the Alfven-cyclotron, mirror and ion Bernstein instabilities driven by a tenuous (1%) warm proton ring velocity distribution with a ring speed, v(r), varying between 2v(A) and ...
