(Universidad de Chile, 2011)En el presente trabajo se analiza la composición mineralógica y química de los sedimentos activos y preindustriales de los principales ríos que conforman la cuenca del Río Limarí (Región de Coquimbo, Chile). El objetivo ...
-
(Springer, 2015)In this note, we obtain some necessary and sufficient conditions for the controllability and observability in a linear time-varying control system with piecewise constant state variables. The controllability results can ...

Controlled dispersion of ZnO nanoparticles produced by basic precipitation in solvothermal processes (Elsevier, 2020)Zinc oxide nanoparticles were successfully synthesized under precipitation processes, using ZnSO4⋅7H2O as a Zn2þ precursor and K2CO3 used as a basic source, and hydrozincite was obtained as an intermediary, which was ...
-
(JOHN WILEY & SONS, 2006-05)Typical small hospital and laboratory equipment and general supplies cannot be anchored to resist earthquake motions. In order to protect these non-structural components, a common procedure is to provide barriers to restrain ...
-
(ELSEVIER, 2006-08)Objective: We compared the effects of an arginine-supplemented diet with those of an isocaloric isonitrogenous diet on immune and metabolic response of children with burns. Methods: This was a double-blind, randomized, ...
-
(Optical Society of America (OSA), 2003)A study was performed on controlled switching of discrete solitons in waveguide arrays. The study involved weak steplike modulation of the coupling strength in the array with the period larger than the waveguide spacing. ...

(Elsevier, 2018-07-14)This study investigates the chemical composition and sensory properties of wines from Cabernet Sauvignon vines grown under controlled water deficit in two consecutive seasons. The wines were made from fruit of grapevines ...
-
(ELSEVIER SCIENCE, 2003-10-15)We demonstrate how to improve the switching power and performance of all-optical nonlinear couplers by introducing linear control waveguides. In particular, we demonstrate this idea for a three-core coupler consisting of ...
-
(GRAZ UNIV TECHNOLGOY, INST INFORMATION SYSTEMS COMPUTER MEDIA-IICM, 2008)Aspect languages provide different mechanisms to control when an aspect should apply based on properties of the execution context. They however fail to explicitly identify and cleanly capture a property as basic as that ...
