Morphological and enzymatic analysis of the midgut of Anopheles darlingi during blood digestion
(Elsevier B.V., 2005-07-01)
The midgut of adult female Anopheles darlingi is comprised of narrow anterior and dilated posterior regions, with a single layered epithelium composed by cuboidal digestive cells. Densely packed apical microvilli and an ...
Role of the surface state and structural feature in the thermoreversible sol-gel transition of a zirconyl aqueous precursor modified by sulfuric acid
(Amer Chemical Soc, 2004-10-19)
The sols produced by admixture of ZrOCl2 acidified solutions to hot H2SO4 aqueous solutions were studied to clarify the effects of Cl- and SO42- ions on the kinetic stability of nanoparticles and to obtain some new evidence ...
Influence of pH of Colloidal Suspension on the Electrical Conductivity of SnO2 thin Films Deposited Via Sol-Gel-Dip-Coating
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2011-01-01)
Tin dioxide (SnO2) thin films are deposited by the dip-coating technique from colloidal suspensions prepared with distinct pH through the sol-gel method. The decrease of the pH contributes to the destruction of an electrical ...
Structural and optical properties of GdAlO3:RE3+ (RE = Eu or Tb) prepared by the Pechini method for application as X-ray phosphors
(Elsevier B.V. Sa, 2009-12-04)
In this work, GdAlO3:RE3+ (RE = Eu or Tb) was successfully prepared by the Pechini method at lower temperatures when compared to others methods as solid-state synthesis and sol-gel process. In accordance to the XRD data, ...

Una comparación del Análisis de Ciclo de Vida entre el árido reciclado y el árido natural
(Fondo Editorial EIA - Universidad EIA, 2022-06-01)
La industria de la construcción consume muchos recursos de la naturaleza y genera una gran cantidad de residuos al medio, en todas las fases del ciclo de vida. Por esta razón cada vez se incentiva más el uso de material ...
Argamassa de revestimento produzida a partir da substituição do agregado natural por resíduo de scheelita e pó de pedra
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA CIVIL, 2021-07-28)
The exploration of aggregates involves the extraction of non-renewable natural resources, and
with that, it modifies the environment, causing environmental impacts. In 2016 alone, Brazil
produced around 312 million tons ...
Comportamento sob altas temperaturas de concretos com agregados reciclados de concreto

Microvesicle release and micellar attack as the alternative mechanisms involved in the red-blood-cell-membrane solubilization induced by arginine-based surfactants
(Royal Society of Chemistry, 2017-03)
Two novel arginine-based surfactants, Bz-Arg-NHC10 and Bz-Arg-NHC12, were characterized with respect to surface properties and their interaction with human red-blood-cell (HRBC) membranes. The values for critical micellar ...
