Background: Metal phosphides are widely used as a rodenticide and insecticide and poisoning with these substances has a very high mortality. The aim of this study was to evaluate the butyrylcholinesterase (BuCh) level in poisoning with metal phosphides. Methods: In this case series study, 60 poisoned patients with zinc phosphide (ZnP) and aluminum phosphide (ALP) who was admitted to poisoning ...

The Wildlife Services (WS) Program manages wildlifelhuman conflicts by using an integrated approach employing some vertebrate pesticides. These are used in such small quantities that private industry cannot afford to register and produce them profitably. On behalf of WS, the Animal and Plant Health Inspection Service (APHIS) maintains about 30 federal and state pesticide registrations, containi...

The field of topological states in phonon solids have been rapidly developing recent years. This work examined the dispersion a compound Boron Phosphide (BP) with Zinc-Blende structure via first-principle calculation. results show that BP is stable theory and hosts rich signatures its dispersion. Specifically, Weyl quadratic nodal line can be found acoustic branches, triple point contact optica...

Tetragonal zinc phosphide (a-Zn3P2) was grown pseudomorphically, by compound-source molecularbeam epitaxy on GaAs(001). The films grew coherently strained, with epitaxial relationships of Zn3P2(004):GaAs(002) and Zn3P2(202):GaAs(111). Partial relaxation of the Zn3P2 lattice was observed for films that were 4150 nm in thickness. Van der Pauw and Hall effect measurements indicated that carrier mo...
