(2008)In this work we report results from continuous-wave (CW) and pulsed electron paramagnetic resonance (EPR) and proton nuclear magnetic resonance (NMR) studies of the vanadium pentoxide xerogel V2O 5:nH2O (n ≈ 1.6). The low ...

(TAYLOR & FRANCIS LTD, 2006)This work describes an Electron Paramagnetic Resonance (EPR) and Nuclear Magnetic Resonance (NMR) study of the vanadium pentoxide xerogel V2O5:nH(2)O with n approximate to 1.8 Experiments were performed in the temperature ...
-
(1989)The spin-lattice interaction, which very recent experiments suggest is significant in the layered perovskites, is modeled by adding to the coupling constant of the anisotropic Heisenberg antiferromagnet a linear dependence ...

(2012)Four novel cobalt(II) complexes mimicking metalloenzyme active sites, novel C 14H 22Cl 12Co 2O 132C 3H 8O (1), C 28H 36Cl 24Co 4O 284C 4H 8O 2 (2), C 16H 22Cl 12Co 2O 13C 2HCl 3O 2 (3), C 16H 22Cl 12Co 2O 13 (4), and one ...
-
(IOP, 2020)A detailed analytic and numerical analysis of the interaction between two bubble skyrmions has been carried out. The results from the micromagnetic calculations show that when the skyrmions are in the same plane, the ...
-
(American Physical Society, 2020)Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet chromium triiodide (CrI3) are studied. We find that bulk magnons exhibit a nontrivial topological band structure without the need for ...
-
(American Physical Society, 2017)© 2017 American Physical Society.We show that the interaction between the spin-polarized current and the magnetization dynamics can be used to implement black-hole and white-hole horizons for magnons - the quanta of ...
-
(1978)Glucokinase is a monomeric protein under native and denaturating conditions yet presents a sigmoidal saturation function for glucose. These peculiarities suggested the possibility that polymerization occurs under assay ...
-
(AEET. Asociación Española de Ecología Terrestre, 2020)La malaria aviar es una enfermedad causada por parásitos sanguíneos transmitidos por mosquitos. En el hospedador, los parásitos infectan órganos y tejidos causando daño celular, afectando finalmente a la condición física ...
-
(2011)We, herein, report evidence that wing fanning by the aphid parasitoid Aphidius ervi Haliday (Hymenoptera: Braconidae) constitutes a courtship song. Complete removal of the forewings or only the distal half of them reduced ...
-
(Marcel Dekker Inc, 2000)Maleic acid-alt-styrene (MAaS) copolymer with number-average molecular weight M̄n = 2500 was used as a compatibilizer in blends of poly(ethylene oxide) (PEO) and poly(styrene) (PS). PEO with weight-average molecular weight ...
-
(Springer, 2010)This article introduces a management tool for salmon farming, with a scope in the local sustainability of salmon aquaculture of the Aysen Fjord, Chilean Patagonia. Based on Integrated Coastal Zone Management (ICZM) principles, ...
-
(Elsevier, 2018-05)Predation on domestic animals by carnivores is a persistent problem wherever carnivores and livestock co-occur A wide range of management tools to reduce predation has been invoked However, the evidence of their effectiveness ...
-
(Elsevier Ltd., 2004-05-26)Abstract—Twenty-nine arylisopropylamines, substituted at the b-position of their side chain by an oxo, hydroxy, or methoxy group, were evaluated in vitro as MAO-A and MAO-B inhibitors. The oxo derivatives (‘cathinones’) ...
-
(AMER SOC CELL BIOLOGY, 2010-08-09)Cultured neurons obtained from MAP1B-deficient mice have a delay in axon outgrowth and a reduced rate of axonal elongation compared with neurons from wild-type mice. Here we show that MAP1B deficiency results in a ...
-
MAP1B-dependent Rac activation is required for AMPA receptor endocytosis during long-term depression (2013)The microtubule-associated protein 1B (MAP1B) plays critical roles in neurite growth and synapse maturation during brain development. This protein is well expressed in the adult brain. However, its function in mature ...
-
(2012)The aim of this piece of research was to study the linguistic vitality of Mapudungún in the city of Santiago de Chile, taking into account for its description the (discursive, lexical, writing and communicative) competence ...
-
(2011)Through an extensive sampling and dating of pairs of associated shells and charcoal fragments combined with reanalysis of all the available previous data, we reconstruct the evolution throughout the Holocene of the regional ...

(Academic Press Inc., 2017)© 2016 Elsevier Inc. Two main hypotheses have been debated about the biogeography of the Southern Ocean: (1) the Antarctic Polar Front (APF), acting as a barrier between Antarctic and sub-Antarctic provinces, and (2) the ...
