(Universidad de Chile, 2023)La enfermedad por coronavirus (COVID‑19) es una enfermedad infecciosa provocada por el virus SARS-CoV-2. Este virus produjo desde el 2019 una pandemia que generó alrededor de 674 millones de personas infectadas y 6,86 ...
-
(Universidad de Chile, 2010)Las prótesis completas maxilomandibulares han sido el estándar tradicional para el cuidado de los pacientes desdentados, pero un número considerable de pacientes no se adaptan, particularmente a la prótesis mandibular. ...

(Elsevier, 2008-10-23)Experimental observations show that for the gas phase isomerization of protonated molecules, a third body can transport a proton from a high-energy site to a lower energy-site of the substrate, thereby catalyzing the ...
-
(Blackwell Publishing Ltd, 2002)We study ion cyclotron instabilities due to the thermal anisotropy of minor heavy ions. Very large thermal anisotropics have been observed in O +5 ions in coronal holes [Cranmer, 2001], and as is well known, the thermal ...
-
(SPRINGER, 2006-08)Host-guest supramolecular complexes are of special interest for understanding the chemistry in low dimensional spaces. The molecular recognition involved in the formation of such structures sometimes may be a relevant model ...
-
(TAYLOR & FRANCIS LTD, 2004-03)The synthesis, crystal structure and properties of a novel ternary inclusion compound formed by protonated bis(quinuclidine) inserted in a urea-chloride anionic host, urea(5)[quinuclidine(2)H]Cl-+(-) (1), are reported. In ...

(2006)Host-guest supramolecular complexes are of special interest for understanding the chemistry in low dimensional spaces. The molecular recognition involved in the formation of such structures sometimes may be a relevant model ...
-
(MDPI AG, 2016)A series of a new type of tetracyclic carbazolequinones incorporating a carbonyl group at the ortho position relative to the quinone moiety was synthesized and analyzed by tandem electrospray ionization mass spectrometry ...
-
(Biophysical Society, 1996)Calsequestrin, a high-capacity, intermediate-affinity, calcium-binding protein present in the lumen of sarcoplasmic reticulum, undergoes extensive calcium-induced conformational changes at neutral pH that cause distinct ...
-
(The American Astronomical Society, 2015)While recent observational progress is converging on the detection of compact regions of thermal emission due to embedded protoplanets, further theoretical predictions are needed to understand the response of a ...
