Energy and exergy assessment in a perimeter cooled data center: the value of second law efficiency (Elsevier, 2017)The Data Center Industry remains in steady growth with worldwide energy consumptions in the order of hundreds of TWh, and yearly growth rates higher than the growth of global electricity consumption. Electronic cooling ...
-
(Sage, 2017-06)Background: Early and optimal energy and protein delivery have been associated with improved clinical outcomes in the pediatric intensive care unit (PICU). Overweight and obese children in the PICU may be at risk for ...
-
(MDPI, 2021)Energy and water have faced important levels of conflicts in the last 20–25 years in Chile. However, the way that they have been politically addressed in the last decade differs. These differences emerge from how these ...
-
(2010)In the absence of comparable macroeconomic indicators for most of the Latin American economies before the 1930s, the apparent consumption of energy is used in this paper as a proxy of the degree of modernization of Latin ...
-
(NATURE PUBLISHING GROUP, 2006-09)Objective: To evaluate energy balance and physical activity in obese preschool children attending day-care centres. Design: Cross-sectional study. Subjects: Twenty-four 3-5 years old obese children selected at random ...
-
(Universidad de Chile, 2021)La soldadura es un método de unión de materiales que sobre metales es bastante usado en la industria. Es interesante notar que los que más entienden son los operarios, quienes regulan los parámetros iniciales. Para los ...
-
(Blackwell Publishing Ltd, 2019)We calculate well-resolved corner frequencies and radiated energies for a set of 96 earthquakes divided into two clusters located in the same tectonic setting but with different depths in northern Chile. Fifty-three shallow ...
-
(Elsevier, 2017)We present a methodology to obtain the energy distribution of the neutron flux of an experimental nuclear reactor, using multi-foil activation measurements and the Expectation Maximization unfolding algorithm, which is ...
-
(Sociedad Medica de Santiago, 2008)Background: The effects of gastric bypass (GBP) on resting energy expenditure (REE) are not well known. Aim: To evaluate the changes in REE and its relationship with body composition in severe and morbid obese women before ...
-
Energy expenditure and intake comparisons in Chilean children 4-5 years attending day-care centres (Aula Médica, 2015)Introduction: the doubly labelled water (DLW) method has an accuracy of 1% and within-subject precision of 5-8%, depending on subject’s age and environments issues. Energy intake assessment is prone to errors (>15- 20%) ...

-
(2011)The Na +/K + pump is a nearly ubiquitous membrane protein in animal cells that uses the free energy of ATP hydrolysis to alternatively export 3Na + from the cell and import 2K + per cycle. This exchange of ions produces a ...
-
Energy management systems for microgrids: main existing trends in centralized control architectures (MDPI, 2020)This paper presents both an extensive literature review and a qualitative and quantitative study conducted on nearly 200 publications from the last six years (based on international experience and a top-down analysis ...
-
(Elsevier Ltd, 2003)Chinchilla brevicaudata lives at 3500-5000 m, with high ambient temperatures during the day but cold at night. In this Andean habitat there is also low availability of food and water resources. Physiological attributes ...

Energy nonequipartition in a collisional model of a confined quasi-two-dimensional granular mixture (American Physical Society, 2020)A collisional model of a confined quasi-two-dimensional granular mixture is considered to analyze homogeneous steady states. The model includes an effective mechanism to transfer the kinetic energy injected by vibration ...
-
(Elsevier Ltd, 2018)This paper presents a method for thermal comfort control for trams which achieves the desired thermal comfort and minimises the power consumption of heating,ventilation and air conditioning (HVAC). Mathematical models of ...
-
(Elsevier, 2003)In several countries (Chile, Bolivia, Argentina and Peru, among others), power plants are dispatched according to merit order, i.e. based on the marginal operating costs of the plants. In this scheme, the operating plant ...
-
(Soc Neuroscience, 2017-06-07)The mechanisms that power the physiological events occurring in cilia, flagella, and microvilli are of fundamental importance for the functions of these important and ubicuous organelles. The olfactory epithelium is mostly ...
