(2011)There is great interest in understanding how extremophilic biomining bacteria adapt to exceptionally high copper concentrations in their environment. Acidithiobacillus ferrooxidans ATCC 53993 genome possesses the same ...
-
(Elsevier, 2019)Aristonectines show a highly derived morphology among elasmosaurid plesiosaurs, including some species with large body size. A new postcranial skeleton is described from the uppermost Maastrichtian levels of the L opez ...
-
(Nature, 2020)Egg size and structure reflect important constraints on the reproductive and life-history characteristics of vertebrates(1). More than two-thirds of all extant amniotes lay eggs(2). During the Mesozoic era (around 250 ...
-
(American Mathematical Society, 2005)For a family of single-species delayed population models, a new global stability condition is found. This condition is sharp and can be applied in both monotone and nonmonotone cases. Moreover, the consideration of variable ...
-
(1990)The aerial parts of Bahia ambrosioides afforded several germacranolides and heliangolides one of which has not been reported previously. Furthermore, in addition to widespread compounds, four 3-hydroxyumbelliferone derivatives ...
-
(Kluwer Academic Publishers, 1987)Questions of successional pattern and causality have been central concerns in vegetation ecology. In this paper we address the limits of the overextended models of Connell and Slatyer by discussing problems encountered in ...
-
(BIOMED CENTRAL LTD, 2010-12-22)Background: Studies on innate immunity have benefited from the introduction of zebrafish as a model system. Transgenic fish expressing fluorescent proteins in leukocyte populations allow direct, quantitative visualization ...
-
(2010)The analysis of a 10 000 calendar year (cal. ka) pollen record on the west coast of Tasmania has revealed a suite of changes that can be related to sea level, fire and people. Fire-promoted moorland has occupied the site ...
-
(AMER INST PHYSICS, 2011-01)Based on the one-body particle-antiparticle Dirac theory of electrons, a set of relativistic quantum fluid equations for a spin half plasma is derived. The particle-antiparticle nature of the relativistic particles is ...
-
(Elsevier, 2018)This paper presents the detailed description of a remarkable skull and partial postcranial skeleton of a very juvenile elasmosaurid referred to Tuarangisaurus keyesi (CD 427), from the upper Campanian-lower Maastrichtian ...
-
(2012)A local measure of the electrophilicity has been recently proposed to analyze the chemical reactivity of several kinds of molecules. In this work a theoretical rationalization of the local extension is proposed following ...

-
(American Institute of Physics, 2021)A simple model for the stochastic evolution of defects in a material under irradiation is presented. Using the master-equation formalism, we derive an expression for the average number of defects in terms of the power flux ...
-
(1995)The variation of the charge capacity of a double‐layer 1T–TiS2 model system upon increasing intercalation with lithium is examined at a molecular level. The charge capacity is modeled through the global hardness index of ...

(John Wiley & Sons, 1994-10-14)The variation of the charge capacity of a double-layer 1T-TiS2 model system upon increasing intercalation with Lithium is examined at a molecular level. The charge capacity is modeled through the global hardness index of ...
-
(1973)Energy gaps near the Fermi surface arising from magnetic Brillouin zone effects must be taken into account in order to understand the antiferromagnetism of europium metal. © 1973 Pergamon Press.
-
(1995)Based upon ab initio Hartree-Fock calculations we propose a model potential for simplifying the study of the internal rotation of neighbouring rings. The quality of the proposed analytic potential was numerically verified ...
-
(John Wiley and Sons Inc., 1998)Using some relationships derived from the density functional version of the virial theorem, an approximated kinetic energy density is constructed. This is used to implement a modified version of the electron localization ...
-
(Portland Press Ltd, 1997)Strains of Escherichia coli bearing different forms of phosphofructokinase were used to assess the occurrence of futile cycling in cell resuspensions supplied with glycerol as gluconeogenic carbon source. A model was used ...
-
(IANDS, 1993)This paper describes a possible near-death experience (NDE) among the Mapuche people of Chile. The individual reporting the experience was in a cataleptic-like state for two days, the experience itself occurring at ...
