(2004)All-electron spin polarized DFT calculations have been performed to optimize the pentagonal bipyramidal (D5h) geometry of the Cu7 cluster by using the B3LYP and the B3PW1 functionals with different basis sets. Dirac ...
-
(Elsevier Science B.V., 1995-01-30)Non-relativistic (NR-Xa) and Dirac (DSW-Xa) spin-restricted calculations on the matrix isolated AU3 cluster are reported. It Ís shown that the resolved hyperfine interactions arising from the apical gold atom and the ...

-
(Royal Society of Chemistry, 2016)Solar power is a strong alternative to the currently used fossil fuels in order to satisfy the world's energy needs. Among them, dye-sensitized solar cells (DSSC) represent a low-cost option. Efficient and cheap dyes are ...
-
(Univ Autónoma Metropolitana-Iztapalapa, México, 2021)It has been demonstrated that some species of the Yucca genus are a source of metabolites with functional properties, as is Yucca carnerosana (Trel.) McKelvey with antifungal activity. This research aimed to induce the ...
-
(1974)A calorimetric investigation of the magnetic-nonmagnetic transition of an impurity (Ce) in a superconducting binary-alloy matrix (La, Th) is reported for the first time. The continuous demagnetization of the Ce ions with ...
-
(Wiley, 2020)CaMK2N1 and CaMK2N2 (also known as CaMKIIN alpha and beta) are endogenous inhibitors of calcium/calmodulin-dependent kinase II (CaMKII), an enzyme critical for memory and long-term potentiation (LTP), a form of synaptic ...
-
(BioMed Central, 2013)CaMKII is a major synaptic protein that is activated during the induction of long-term potentiation (LTP) by the Ca2+ influx through NMDARs. This activation is required for LTP induction, but the role of the kinase in the ...
-
(2013)Urban growth is a strong driver of habitat degradation and loss. In spite of that, a surprising diversity of native species may survive in urban areas. In the La Paz, Bolivia metropolitan area and surroundings, local ...
-
(Springer Netherlands, 2018)© 2018, Springer Science+Business Media B.V., part of Springer Nature. The assessment of visitors’ willingness to pay (WTP) to achieve scenarios that guarantee good conservation status in protected areas and that positively ...
-
(IOP Publishing, 2013)The Lagrangian equations of motion for massive spinning test particles (tops) moving on a gravitational background using general relativity are presented. The paths followed by tops are nongeodesic.An exact solution for ...
-
(SPRINGER, 2010-10)Despite the increasing claims that structural complexity in agroforestry plantations is a key variable for enhancing bird biodiversity, few studies have experimentally manipulated the understory component of structural ...

-
(BMC, 2018)Background: Parasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes ...
-
(Sage, 2015)We set out to test the ability to detect vegetation change from organic soil nutrient (carbon and nitrogen) composition in the fire-determined forest/ non-forest mosaic of western Tasmania, Australia. We find no relationship ...
-
(Springer, 2010)Cannibalism refers to the action of consuming a member of the same species and is common in many taxa. This paper reviews the available literature on cannibalism in cephalopods. All species of the class Cephalopoda are ...
-
(Universidad de Tarapacá, Facultad de Ciencias Sociales Administrativas y Económicas, Departamento de Antropología, 2005-12)Con el objeto de estudiar la procedencia de obsidianas encontradas en sitios arqueológicos y caracterizar fuentes de obsidiana en distintas partes de Chile, iniciamos un estudio de caracterización de fuentes por medio de ...
-
(Universidad de Concepción. Facultad de Ciencias Naturales y Oceanográficas., 2015)Los peces muestran una amplia diversidad de comportamientos alimentarios, algunas veces asociados con morfologías específicas, las cuales pueden reflejar adaptaciones para usar los recursos dependiendo de su hábitat. En ...
-
(SPRINGER, 2008-06)Carbon allocation within a plant depends on complex rules linking source organs (mainly shoots) and sink organs (mainly roots and fruits). The complexity of these rules comes from both regulations and interactions between ...
