(2001)We used experimental nests baited with California Quail (Callipepla californica) eggs or clay eggs to examine relative risks of nest predation in an agricultural landscape and in two large forest preserves in a south-temperate ...

(American Society of Mammalogists, 2008-07-22)Brachydelphis mazeasi Muizon, 1988a, from the Pisco Formation (middle Miocene, Peru), is an odontocete originally known from 2 incomplete skulls and a few associated postcranial elements, assigned to the family Pontoporiidae, ...
-
(SOC BIOLGIA CHILE, 2008-03)The current geographical distribution of alien species could be informative of processes involved in the biological invasions facilitated by humans. Because environmental and anthropic factors affect the geographic ...

(Public Library Science, 2015)Proteins containing Zn(II)(2)Cys(6) domains are exclusively found in fungi and yeasts. Genes encoding this class of proteins are broadly distributed in fungi, but few of them have been functionally characterized. In this ...
-
(MDPI, 2022)The discovery of penicillin entailed a decisive breakthrough in medicine. No other medical advance has ever had the same impact in the clinical practise. The fungus Penicillium chrysogenum (reclassified as P. rubens) has ...
-
(Elsevier, 2017)The properties of nanometric materials make nanotechnology a promising platform for tackling problems of contemporary medicine. In this work, gold nanorods were synthetized and stabilized with polyethylene glycols and ...
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2011)The quality requirements that consumers consider in their decision to purchase fresh fruit have garnered a great deal of attention from the actors in the fresh fruit productivity chain. This study seeks to identify attributes ...

Percolation of influenza AH1N1 epidemic in the world: Usefulness of the spatial-connectivity models (SOC. MEDICA SANTIAGO, 2010-03-31)The 2009 AH1N1 epidemics expanded rapidly around the world by the current connectivity conditions. The spread of epidemics can be described by the phenomenon of percolation, that allows the estimation of the threshold ...

(2013)Weakly bonded Cadmium clusters have, even for small number of atoms, many isomers that are stable structures. Before any attempt to use ab initio calculations on these clusters, a limited set of good possible stable isomers ...

(Frontiers Media, 2021)Variations in the availability of nutritional resources in animals can trigger reversible adjustments, which in the short term are manifested as behavioral and physiological changes. Several of these responses are mediated ...
-
(NATL ACAD SCIENCES, 2001-08-14)Upon depolarization positive charges contained in the transmembrane segment S4 of voltage-dependent channels are displaced from the cytoplasmic to the external milieu, This charge movement leads to channel opening. In ...
-
(Springer Basel, 2014)In this paper, we prove the maximal regularity property of an abstract fractional differential equation with finite delay on periodic Besov and Triebel–Lizorkin spaces and use these results to guarantee the existence and ...
-
(2013)Using operator valued Fourier multipliers, we characterize maximal regularity for the abstract third-order differential equation αu′″ (t)+u″ (t) = βAu(t)+γBu′(t) + f(t) with boundary conditions u(0) = u(2π), u′(0) = u′(2π) ...
-
(UNIV SZEGED, BOLYAI INSTITUTE, 2010)In this paper we investigate the existence of the periodic solutions of a quasilinear differential equation with piecewise constant argument of generalized type. By using some fixed point theorems and some new analysis ...
-
(BIRKHAUSER VERLAG AG, 2011-03)In this paper, we give a necessary and sufficient conditions for the existence and uniqueness of periodic solutions of inhomogeneous abstract fractional differential equations with delay. The conditions are obtained in ...
-
(Wiley, 2017)We characterize the existence of periodic solutions for some abstract neutral functional fractional differential equations with finite delay when the underlying space is a UMD space.
