Synthesis of silver nanoparticles using Bacillus velezensis M3-7 lipopeptides: Enhanced antifungal activity and potential use as a biocontrol agent against Fusarium crown rot disease of wheat seedlings
(
Elsevier
, 2023 , Article)
Bacillus velezensis M3-7 is a hyperactive mutant, 12-fold improved in its antifungal activity, obtained during a previous study from the wild strain BLB371 after a combination of random mutagenesis and medium component ...
Foraging and habitat use of common duikers, Sylvicapra grimmia, in a heterogeneous environment within the Soutpansberg, South Africa
(
Wiley-Blackwell
, 2015 , Article)
We investigated aspects of the foraging behaviour and activity patterns of free-ranging common duikers (Sylvicapra grimmia) within the Soutpansberg, South Africa. We used giving-up densities (GUD) and camera traps to test ...

The basis number of the strong product of paths and cycles with bipartite graphs
(
Central Missouri State University
, 2007 , Article)
The basis number of a graph G is defined to be the least integer d such that there is a basis B of the cycle space of G such that each edge of G is contained in at most d members of B. MacLane [13] proved that a graph G ...
