Dissipation in Quantum Mechanics took some time to become a robust field of investigation after the birth of the field. The main issue hindering developments in the field is that the Quantization process was always tightly connected to the Hamiltonian formulation of Classical Mechanics. In this paper we present a quantization process that does not depend upon the Hamiltonian formulation of Classical...
The fluid catalytic cracking (FCC) process is the main source for sulfur emission in the refinery. DeSOx additive comprises two main steps, i.e. SO2 oxidation to SO3 and trap through sulfate formation, followed by reduction to H2S. This work describes the application of undoped and iron doped Manganese Oxide Octahedral Molecular Sieves, OMS-2 and Fe/OMS-2, as potential catalysts for DeSOx in FCC....
Botulism is a paralytic disease caused by intoxication with neurotoxins produced by Clostridium botulinum. Despite their similar mechanism of action, the botulinum neurotoxins (BoNT) are classified in eight serotypes (A to H). As to veterinary medicine, the impact of this disease is essentially economic, since different species of production animals can be affected, especially by BoNT/C and D. In...
Accidents caused by brown spiders (Loxosceles genus) are frequent in Brazil and are associated with dermonecrotic lesions and, eventually, systemic reactions that may be lethal. The major species implicated with human envenoming have been: L. intermedia, L. gaucho and L. laeta. In this study we characterized the venom from Loxosceles similis, a species of spider normally found inside caves. L. similis...
