(Universidad de Chile, 2014)
-
(Springer, 2017)Conceptual DFT and quantum chemical topology provide two different approaches based on the electron density to grasp chemical concepts. We present a model merging both approaches, in order to obtain physical properties ...
-
(SUOMALAINEN TIEDEAKATEMIA, 2006)This article deals with the conjugacy problem of uniformly quasisymmetric groups of circle homeomorphims to groups of Mobius transformations. We prove that if the involved maps have some degree of regularity and the uniform ...
-
(2014)A study about the oxidative coupling of some representative carbo-and heterocyclic non-symmetrical quinones with aryl-and alkylamines, was carried out comparing dichloromethane and water as reaction mediums. We found that ...
-
(1988)Microinjection of the activated ras oncogenic protein can induce the meiotic maturation of Xenopus laevis oocytes, a process that can also be triggered by progesterone or high concentrations of insulin. Cycloheximide and ...
-
(Universisdad de Chile, 2013)Con el objetivo de estudiar la propagación no lineal de ondas en plasmas relativistas de electrones y positrones, hemos estudiado los decaimientos paramétricos de ondas circularmente polarizada a lo largo de un campo ...
-
(Oxford University Press, 2019)Mitochondrial genomes can provide valuable information on the biology and evolutionary histories of their host organisms. Here, we present and characterize the complete coding regions of 107 mitochondrial genomes (mitogenomes) ...
-
(Pennsylvania State University, 2014)In lizards, one of the most important behavioral mechanisms to cope with spatial and temporal variations in thermal resources observed is activity time. The longer a lizard can maintain activity, the more time it has to ...
-
(Wiley, 2021)The establishment of species boundaries has been a difficult task for biologists since the beginning of classifications. Within South American Allioideae (= Alliaceae), the delimitation of genera and species has long been ...

(Nature Publishing Group, 2018)The Southern Westerly Winds (SWW) are the surface expression of geostrophic winds that encircle the southern mid-latitudes. In conjunction with the Southern Ocean, they establish a coupled system that not only controls ...
-
(ELSEVIER SCIENCE BV, 2010-06-26)Molecular dynamic simulations of shockwaves in solid argon were performed. The simulation cell contains 51,840 atoms at 5 K interacting by means of a pairwise potential. The shockwave itself was introduced explicitly in ...
-
(Elsevier Ltd, 2016)© 2015 Elsevier B.V. All rights reserved.We present a computational tensile test which shows the evolution of the atomic structure of a Cu50Zr50 metallic glass nanowire at 300 K as the applied strain increases. The system ...
-
(Universisdad de Chile, 2016)En los mamíferos, el sistema olfatorio accesorio o vomeronasal (SVN) esta involucrado en el desencadenamiento y en la modulación de las conductas sociales y sexuales, mediante la recepción de semioquimicos. El SVN esta ...
-
(1984)Membranes were obtained from Xenopus laevis oocytes after removal of follicular cells by collagenase treatment. [32P]ADP-ribosylation with pertussis toxin showed them to contain a single Mr = 40 000 substrate for this toxin ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2010-05-24)Patterns of cytoplasmic movements and organization of transport pathways were examined in live or fixed zygotes and early zebrafish embryos using a variety of techniques. The zygote blastodisc grows by accumulation of ...

(2014)Satellite glial cells (SGCs) are the main glia in sensory ganglia. They surround neuronal bodies and form a cap that prevents the formation of chemical or electrical synapses between neighboring neurons. SGCs have been ...
