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 ...
Promoting a Juvenile Awards Approval Plan: Using Collaboration and Selected Projects for Improved Visibility and Findabilty to Promote Juvenile Collections in Academic Libraries
(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 ...

Purinergic P2Y2 Receptor Control of Tissue Factor Transcription in Human Coronary Artery Endothelial Cells NEW AP-1 TRANSCRIPTION FACTOR SITE AND NEGATIVE REGULATOR
(2020-04-08)
We recently reported that the P2Y2 receptor (P2Y2R) is the predominant nucleotide receptor expressed in human coronary artery endothelial cells (HCAEC) and that P2Y2R activation by ATP or UTP induces dramatic up-regulation ...
Quantification of the Atmospheric Relativistic Electron Precipitation on 17 January 2013
(2022-09-29)
On 17 January 2013, relativistic electron precipitation (REP) was observed on Balloon Array for Radiation Belt Relativistic Electron Losses (BARREL) payloads, National Oceanic and Atmospheric Administration Polar orbiting ...
Quasiparticle virtual orbitals in electron propagator calculations
(2021-01-26)
The computational limits of accurate electron propagator methods for the calculation of electron
binding energies of large molecules are usually determined by the rank of the virtual orbital space.
Electron density ...
