Amphibian biodiversity is in rapid global decline, due in part to the fungal disease chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd). Susceptibility to Bd and chytridiomycosis varies between species and populations. Skin peptides and symbiotic skin bacteria appear to be important mechanisms of Bd resistance. However, not much is known about...
Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination
with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1]
heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate.
Studies were conducted in coastal lakes of Oregon infested with E.
densa. Dichlobenil (2, 6 dichlorobenzonitrile)...

The aims of physical education in Ghana include developing personal qualities
such as competence in students and generating interest in physical education and sports
(Ghana Education Service, [GES], 1987). The GES has also reiterated the need to have
competent teachers in the implementation of the school physical education syllabus;
therefore...
The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...
