Diversities, hyperconvexity and fixed points
(Elsevier, 2014-01)
Diversities have been recently introduced as a generalization of metrics for which a rich tight span theory could be stated. In this work we take up a number of questions about hyperconvexity, diversities and fixed points ...

Study of the dehydroxylation-rehydroxylation of pyrophyllite
(American Ceramic Society, 2010)
Pyrophyllite is a raw material of significant interest due to its large number of applications. Most of these applications require a thermal transformation of pyrophyllite; this thermal transformation implies the release ...

Preparation of calcium carbonate as nanoparticles from inorganic precursors and sucrose as additive with potential application as biomaterial
(Elsevier, 2016)
In this communication, it is reported the first relevant results on a broad study on the preparation of calcium carbonate as precipitated nanoparticles of the polymorphs vaterite and calcite. The inorganic precursors are ...

Designing ecotourism routes with time-dependent benefits along arcs and waiting times at nodes
(MDPI, 2024-02-20)
Ecotourism routes serve as powerful tools for fostering environmental awareness. To achieve this, it is crucial to design itineraries within natural parks that strike a balance between visitor experience and ecological ...

Coastal Ecosystems as Sources of Biofertilizers in Agriculture: From Genomics to Application in an Urban Orchard
(Frontiers Media, 2021)
Pantoea agglomerans RSO7, a rhizobacterium previously isolated from Spartina maritima grown on metal polluted saltmarshes, had demonstrated good plant growth promoting activity for its host halophyte, but was never tested ...

Thermodynamic properties of the parabolic-well fluid
(Frontiers Media S.A., 2021)
The thermodynamic properties of the parabolic-well fluid are considered. The intermolecular interaction potential of this model, which belongs to the class of the so-called van Hove potentials, shares with the square-well ...

Toward fluorinated aminoglycosides: Structural studies of phenylhydrazine condensation with carbohydrate derivatives
(Georg Thieme Verlag, 2013)
The reaction of phenylhydrazine with a sugar dialdehyde in water, as a key step for the synthesis of the 3-amino-3-deoxy-d-glucose moiety contained in kanamycin, has been revisited. Structural studies (IR and NMR as well ...

Cadmium removal by Anabaena sp. ATCC 33047 immobilized in polyurethane foam
(Springer, 2015)
The nitrogen-fixing cyanobacterium Anabaena sp. ATCC 33047, which generates substantial amounts of exopolysaccharide, was immobilized by entrapment within the reticulate network of polyurethane foam discs. The immobilized ...

Random and stochastic disturbances on the input flow in chemostat models with wall growth
(Taylor and Francis, 2019-05-03)
In this paper, we analyze a chemostat model with wall growth where the input flow is perturbed by two different stochastic processes: the well-known standard Wiener process, which leads into several draw- backs from the ...
