(John Wiley and Sons Inc., 2014)© 2014 Wiley Periodicals, Inc.In this article, innovative applications of amphiphilic triblock and pentablock copolymers in the synthesis of gold nanoparticles are reported. The synthesis of gold nanoparticles is performed ...
-
(1989)It has been established that early events in lymphocyte activation involve a rise in intracellular Ca++ as well as changes in the flux of other ions. Although a Ca++ channel has been postulated to participate in the early ...
-
(ASME-AMER SOC MECHANICAL ENG, 2006-08)Blood flow dynamics under physiologically realistic pulsatile conditions plays an important role in the growth, rupture, and surgical treatment of intracranial aneurysms. The temporal and spatial variations of wall pressure ...
-
(MDPI, 2022)Mepraia parapatrica is one of the lesser known and less abundant sylvatic triatomine species naturally infected by the protozoan Trypanosoma cruzi, the etiological agent of Chagas disease. M. parapatrica lives in sympatry ...
-
(Wiley, 2020)1. Blood-feeding bugs in the Triatominae are the vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Mepraia is a sylvatic genus endemic to Chile that transmits T. cruzi in the wild cycle. 2. ...
-
(Elsevier, 2015)Rufous-collared sparrows (Zonotrichia capensis peruviensis) from valleys in the Atacama Desert of Chile, live in an extremely stable environment, and exhibit overlap in molt and reproduction, with valley-specific differences ...
-
(2012)We studied the renal morphology of 16 species of passerines to assess whether the composition of the diet of birds have been paralleled by differences in the characteristics of the kidneys. We determined the number and ...
-
(Sociedad Mexicana de Fisica, 2002)We consider a macroscopic body propagating in a one-dimensional resistive medium, consisting of an ideal gas at temperature T. For a whole family of collisions with varying degree of inelasticity, we find an exact expression ...
-
(Sociedad Mexicana de Fisica, 2001)We introduce and solve in closed form, using momentum and kinetic energy balance, a simplified microscopic model of a body propagating in a one dimensional resistive medium. For a whole family of collisions with varying ...
-
(Springer-Verlag, 1988)An inferential analysis of the foraging mode (opportunist or mediate by prey selection) of a taxonomic assemblage of raptors in central Chile was conducted. The analysis of energetic aspects such as daily requirements of ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-06)There is an exceptional group of alpine peatlands in the world situated in the and grasslands of the central Andes. The peatlands in northern Chile occur in the most arid part of their range. Members of the Juncaceae are ...
-
(Amer Inst Physics, 2021)In the Madelung-Bohm approach to quantum mechanics, we consider a time dependent phase that depends quadratically on position, and we show that it leads to a Bohm potential that corresponds to a time dependent harmonic ...
-
(The Italian Pharmacological Society, 1993-06-02)Boldo (Peumus boldus Mol.), a Chilean tree traditionally employed in folk medicine and recognized as a herbal remedy in a number of pharmacopoeias, mainly for the treatment of liver ailments, has recently been the subject ...

Bond Fukui Functions As Descriptor of the Electron Density Reorganization in pi Conjugated Systems (AMER CHEMICAL SOC, 2012-01-06)The bond Fukui function is introduced and tested as a new reactivity index capable of predicting the evolution of bond breaking and formation processes during an organic reaction involving pi conjugated systems. As an ...

(American Chemical Society, 2011-11-29)The bond Fukui function is introduced and tested as a new reactivity index capable of predicting the evolution of bond breaking and formation processes during an organic reaction involving π conjugated systems. As an ...
-
(2001)The electron localization function (ELF) has been used to study the bonding characteristics of the hydrogenated lithium clusters. The analysis of the ELF clearly confirmed the hypothesis that each hydrogen atom added to ...
-
(1995)Bone mineralization was evaluated in 36 school age children with calcium intake below 50% of Recommended Dietary Allowances (RDA), and compared with 28 school age children with calcium intake higher than 100% of the RDA. ...
-
(Wiley, 2020)Apple (Malus domestica) fruits accumulate negligible levels of carotenoids, antioxidant pigments that are precursors for vitamin A in humans. As vitamin A deficiency is an important public health issue, we aimed at increasing ...
-
(North Carolina State University, 2019)Constructed wetlands (CW) are being explored as an alternative treatment for boron removal. The efficiency of CW strongly depends on the substrate and plants used. A promising and inexpensive substrate is rice husk. This ...
