Structural Modifications of Fructans in Aloe barbadensis Miller (Aloe Vera) Grown under Water Stress (2016)Aloe barbadensis Miller (Aloe vera) has a Crassulaceae acid metabolism which grants the plant great tolerance to water restrictions. Carbohydrates such as acemannans and fructans are among the molecules responsible for ...

(2010)We have identified phenazine 5,10-dioxides as prodrugs for antitumour therapy that undergo hypoxic-selective bioreduction to form cytotoxic species. Here, we investigated some structural modifications in order to find new ...
-
(OXFORD UNIV PRESS, 2006)Chile pioneered a structural reform in Latin America that privatized its public pension system and influenced similar reforms in another nine countries. Twenty-five years later, this article evaluates the macroeconomic, ...
-
(Universidad de Chile, 2013)To date, most of the existing standard grammatical descriptions of the English language have used decontextualised written sentence tokens as their primary source of data. However, these standard grammatical descriptions ...

(Elsevier, 2014)Circular-arc graphs are the intersection graphs of open arcs on a circle. Circle graphs are the intersection graphs of chords on a circle. These graph classes have been the subject of much study for many years and numerous ...
-
(Elsevier, 2018)In this paper, a new approach is developed for structural shape optimization, which consists in coupling the particle swarm optimization (PSO) algorithm and the isogeometric boundary element method (IGA-BEM). The IGA-BEM ...
-
(2012)Optically active poly(amide-imide) oligomers were synthesized by direct polycondensation between an aromatic diamine and a dicarboxylic acid both containing a diphenylsilylene unit. The reaction was carried out using ...
-
(2012)Inaccurate wiring and synaptic pathology appear to be major hallmarks of schizophrenia. A variety of gene products involved in synaptic neurotransmission and receptor signaling are differentially expressed in brains of ...
-
(Elsevier, 2013)I build a large-firm model of the labor market with matching frictions and firm turnover. Firms hire both labor and capital. The model allows me to assess the impact of two regulatory frictions on unemployment: i) the ...
-
(American Chemical Society, 2018)In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on Ce-III and containing Co-II or Cu-II cations, assembled by the bifunctional ligand 1H-imidazole-4 ...
-
(Springer, 2020)BiFeO3 was synthesized by conventional solid-state reaction method, and its structural, vibrational, electrical, ferroelastic, and multiferroic properties were studied. X-ray diffraction analysis and Rietveld refinement ...
-
(ELSEVIER, 2006-09-15)The monovacancy and the divacancy in single-walled carbon nanotubes (CNTs) are addressed by spin-density functional calculations. We study these defects in four nanotubes, the armchair (6,6) and (8,8) and the zigzag (10, ...
-
(2016)Transition metal alloy nanoparticles are of interest both theoretically and experimentally, particularly due to their potential technological applications, and to their novel structural and magnetic properties in the ...
-
(American Chemical Society, 2017)© 2017 American Chemical Society. Different polymorphs of Nb2O5 can be obtained depending on the pressure and temperature of calcination leading to different catalytic properties. Two polymorphs of niobia, T-Nb2O5 and ...
-
(Elsevier, 2018-09)Herein, we report the structure, morphology, optical and magnetic properties of novel Ag3(2+x) InxNb4-xO11+delta (0.25 <= x <= 1.0; Al-A4) nanoparticles prepared by sol-gel technique. The samples were studied using X-ray ...
