Biological insecticides based on Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) can efficiently control S. exigua larvae on field and greenhouse crops in many parts of the world. Spanish wild populations and laboratory colonies of S. exigua are infected by two iflaviruses (SeIV-1 and SeIV-2). Here we evaluated the effect of iflavirus co-infection on the insecticidal characteristics of...

The selenium-enriched Scenedesmus biomass of patented selenium-resistant strain SeIV was tested in a broiler chicken diet in comparison with sodium selenite supplementation. Feed conversion, mortality and live weight were not significantly influenced by the source of selenium. Supplementation of either form of selenium significantly increased the Se concentration in breast muscle with a more pr...

reagents for PtII determination in aqueous micellar solutions has been reported.1 It is believed that complexation of the PtII ion with these ligands is accompanied by a unique redox reaction of the PtII complexes (Scheme 1). These complexes exhibit peculiar and huge absorption having a molar absorptivity (ε >104 to 105 l mol–1 cm–1) in the near-infrared (NIR) region of 700 to 900 nm when they ...

The control of epidemics taking place in complex networks has been an increasingly active topic public health management. In this article, we propose efficient networked epidemic system, where a modified susceptible-exposed-infected-vigilant (SEIV) model is first built to simulate spreading. Then, different from existing continuous resource models which abstractly map resources parameters model...
