(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-06-01)This paper deals with the asymptotic stability analysis of a discrete dynamical inclusion whose right-hand side is a convex process. We provide necessary and sufficient conditions for weak asymptotic stability, and obtain ...
-
(Elsevier Science BV, 2018)A novel core-shell K/Cu/SmCe@TiO2 catalyst is here reported being highly active on the selective reduction of nitric oxide with carbon monoxide under oxidizing conditions. It was found that the reaction proceeds with the ...
-
(ELSEVIER SCIENCE BV, 2016)A novel Pt-free Rb/Cu/YCeO2 catalyst was applied to the adsorption of NO under oxidizing conditions. The results show a much greater performance of this catalyst relative to a Pt/Ba/Al2O3 catalyst. The results suggest that ...

-
(Public Library Science, 2016)For marine invertebrates with a benthic adult form and a planktonic larva phase, the connectivity among populations is mainly based on larval dispersal. While an extended larval phase will promote gene flow, other factors ...
-
(2010)In man, infection with South American Andes virus (ANDV) causes hantavirus cardiopulmonary syndrome (HCPS). HCPS due to ANDV is endemic in Southern Chile and much of Argentina and increasing numbers of cases are reported ...
-
(Elsevier, 2020)Multifunctional chitosan/magnetite (CS/Fe3O4) and graphene/chitosan/magnetite (Gr/CS/Fe3O4) nanocomposites (NCs) were synthesized using a simple hydrothermal method. The NCs were subsequently evaluated as magnetic ...
-
(MDPI, 2021)Water pollution by heavy metals has significant effects on aquatic ecosystems. Copper is one of the heavy metals that can cause environmental pollution and toxic effects in natural waters. This encourages the development ...
-
(Royal Society of Chemistry, 2018)This work describes the design, synthesis and physicochemical properties of the highly emissive nanocomposite [bentonite][Eu{(η5-Cp*)Ru(η6-bzac)}3Phen]0.09[H2O]0.22 based on the Eu(III) complex [Eu{(η5-Cp*)Ru(η6-bzac)}3P ...
-
(1994)Trypanosoma cruzi from 23 chronic and acute cases of Chagas disease were isolated and further characterized. They displayed a remarkable similarity, after typification by schizodeme analysis using restriction endonuclease ...
-
(1991)The aerial parts of Senecio zoellneri afforded, in addition to known compounds, five oxygenated furoeremophilane derivatives and three seco-furoeremophilanolides, all of which are probably formed by oxidation of ...
-
(1991)The aerial parts of Polyachyrus sphaerocephalus gave seven new eudesmane derivatives and a germacra-dien-diol while a reinvestigation of P. fuscus afforded a new caryophyllene, two nerolidolglycosides, a curcumene and two ...
-
(1988)The aerial parts of Oxyphyllum ulicinum afforded, in addition to known compounds, 15 new germacrane derivatives with a 1β, 10α-epoxide, a carboxyl group at C-4, and different ester groups at C-9 and C-14. From the aerial ...
-
(ELSEVIER SCIENCE BV, 2004-11-01)The formation of polymeric hybrid materials of siloxanes with gelatin (GE) starting from sodium metasilicate as the silica source, and their transformation into silica under different conditions have been studied. ...
-
(IOP, 2020)Plasma-facing materials (PFMs) for nuclear fusion, either in inertial confinement fusion (ICF) or in magnetic confinement fusion (MCF) approaches, must withstand extremely hostile irradiation conditions. Mitigation strategies ...
-
(Elsevier, 2018)Peridotite xenoliths collected from alkali basalts in the Argentinian Patagonia reveal the existence of an ancient depleted Paleoproterozoic mantle that records a subsequentmultistage metasomatic history.Metasomatismis ...
-
(1996)Aldol reactions lithium alkyl acetates (LiCRR″CO2R′) with (RS)-2-(p-tolylsulfinyl)cyclohexanone (1) (as an epimeric mixture at C-2) take place with very efficient control of the configuration at the tertiary hydroxylic ...
-
(Royal Society of Chemistry, 2016)A microwave-assisted method for the synthesis of tetracyclic tetra-hydropyridines via an intramolecular imino-Diels-Alder reaction in water is reported. The reaction proceeds under catalyst-free conditions and shows excellent ...
