(2016)Phyllotis limatus is an inhabitant of the Atacama Desert, where it is distributed in arid costs and Pacific Andean slopes, reaching 4.000 meters. With the implementation of a study of wildlife in a Chilean Prepuna area, ...
-
(2010)The Density Functional Theory of chemical reactivity has provided and effective way to develop a mathematical framework for many empirical chemical concepts. In this work, the relation of some of the proposed indexes ...
-
(1999)The dipole polarizability of a series of clusters of the type LinHm has been calculated using density functional methods. The study of the trends in the mean polarizability and the anisotropy are explained in terms of the ...
-
(2007)Electronic structure and chemical reactivity of Cun clusters (n = 1-4) supported on a regular site (O5c) and on an oxygen vacancy (Fs and Fs+) of the MgO (1 0 0) surface were investigated using density functional theory. ...
-
(2002)The molecular mechanisms for the cycloaddition reactions of four low activated 1,3-butadiene systems (1,3-butadiene, (E)-1,3-pentadiene, (Z)-1,3-pentadiene, and 4-methyl-1,3-pentadiene) with dimethyl acetylenedicarboxylate ...
-
(2014)We carried out an investigation and analysis of the relationships between the electronic structure and the metabotropic glutamate receptor subtype 5 affinity for a series of 2-amino- and 2-halothiazole derivatives using ...
-
(2010)Stress can be understood as a threat to psychological or physiological integrity of the individual. Stress has previously shown to alter morphology and function of diverse structures of the Central Nervous System related ...
-
(Elsevier, 2015)Complexities in the rupture process during a megathrust earthquake can be attributed to the combined effect of inhomogeneous distribution of stress accumulated during the interseismic period and inho-mogeneous rheology of ...
-
(2009)In a recent series of papers, Higuchi and Higuchi defined an extended constrained-search procedure by extending the Levy constrained search by adding additional constraints. As shown here, this procedure can be equivalently ...
-
(2014)La ansiedad dental es un fenómeno que influye notablemente en el estado de salud oral, entorpeciendo tanto el manejo del paciente durante la atención dental como la posterior adherencia a tratamiento. Con tasas de prevalencia ...

-
(Hindawi Publishing Corporation, 2012)The purpose of this study was to assess the prevalence of dental caries, tooth loss, and risk factors among adult population of Chile. Furthermore, age, gender, and behavioural specific differences in caries prevalence and ...
-
(2015)Purpose: The purpose of this study was to evaluate the relationship between early dental experiences and clinical indicators of oral health and dental anxiety upon admission to a comprehensive oral health program for ...
-
(Blackwell Munksgaard, 1998)The purpose of this case-control study was to determine the association between very-mild-to-moderate enamel fluorosis and exposure during early childhood to fluoridated water, mainly through ingestion of powdered milk. ...
-
(Springer Verlag, 2019)© 2019, The Author(s).Objectives: Dental malocclusions in modern populations would be the result of small and weak jaws developing under low masticatory loads. We assess the validity of this by characterising the external ...
