Abstract Passion fruit (Passiflora spp.) yield is limited by several factors, including soil pathogens, such as Rotylenchulus reniformis (the reniform nematode) and Meloidogyne incognita Southern root-knot nematode). Understanding the behavior of different cultivars, within species passion could be important asset to search for sources resistance, therefore effective management phytonematodes. ...

A positive dynamical system is said to be persistent if every solution that starts in the interior of the positive orthant does not approach the boundary of this orthant. For chemical reaction networks and other models in biology, persistence represents a non-extinction property: if every species is present at the start of the reaction, then no species will tend to be eliminated in the course o...

Manganese porphyrins have been extensively investigated as model systems for the natural enzyme cytochrome P450 and as synthetic oxidation catalysts. Here, we report single-molecule studies of the multistep reaction of manganese porphyrins with molecular oxygen at a solid/liquid interface, using a scanning tunnelling microscope (STM) under environmental control. The high lateral resolution of t...
