Development Length of Fluids Modelled by the gPTT Constitutive Differential Equation

open access: yesApplied Sciences, 2021
In this work, we present a numerical study on the development length (the length from the channel inlet required for the velocity to reach 99% of its fully-developed value) of a pressure-driven viscoelastic fluid flow (between parallel plates) modelled ...

Ester Production Using the Lipid Composition of Coffee Ground Oil (Coffea arabica): A Theoretical Study of Eversa® Transform 2.0 Lipase as an Enzymatic Biocatalyst

open access: yesCompounds, 2023
The scientific community recognizes coffee grounds (Coffea arabica) as an important biological residue, which led to using the Eversa® Transform 2.0 lipase as an in silico enzymatic catalyst for coffee grounds’ free fatty acids (FFA).

Indirect Manganese Removal by Stenotrophomonas sp. and Lysinibacillus sp. Isolated from Brazilian Mine Water

open access: yesBioMed Research International, Volume 2015, Issue 1, 2015., 2015
Manganese is a contaminant in the wastewaters produced by Brazilian mining operations, and the removal of the metal is notoriously difficult because of the high stability of the Mn(II) ion in aqueous solutions. To explore a biological approach for removing excessive amounts of aqueous Mn(II), we investigated the potential of Mn(II) oxidation by both ...

Type IV Secretion System Is Not Involved in Infection Process in Citrus

open access: yesInternational Journal of Microbiology, Volume 2014, Issue 1, 2014., 2014
The type IV secretion system (T4SS) is used by Gram‐negative bacteria to translocate protein and DNA substrates across the cell envelope and into target cells. Xanthomonas citri subsp. citri contains two copies of the T4SS, one in the chromosome and the other is plasmid‐encoded. To understand the conditions that induce expression of the T4SS in Xcc, we

Effective lagrangian for a mass dimension one fermionic field in curved spacetime

open access: yesJournal of High Energy Physics, 2018
In this work we use momentum-space techniques to evaluate the propagator G(x, x ′) for a spin 1/2 mass dimension one spinor field on a curved Friedmann-Robertson-Walker spacetime.

Molecular Dynamics of Film Formation of Metal Tetrasulfonated Phthalocyanine and Poly Amidoamine Dendrimers

open access: yesJournal of Nanomaterials, Volume 2013, Issue 1, 2013., 2013
We performed molecular dynamics computer simulations to elucidate the behavior and properties of the metal tetrasulfonated phthalocyanine molecule and the poly(amidoamine) dendrimers in self‐assembly depositions, respectively, on poly(allylamine hydrochloride) polymer and on film formed by metal tetrasulfonated phthalocyanine with poly(allylamine ...
