(Universidad de Chile. Facultad de Arquitectura y Urbanismo. Departamento de Geografía, 2013-12)Rock glaciers and debris covered glaciers are often understudied in comparison to their uncovered glacial counterparts (in which stunning surface ice is clearly visible). However, rock glaciers and debris covered glaciers ...

(Wiley, 2018)BACKGROUNDControlled water deficits affect grape berry physiology and the resulting wines, with volatile composition being the one of the affected parameters. However, there is a potential disconnect between aromatic ...
-
(Oxford University Press, 2003)Analysis of two water subsidy schemes--a means-tested subsidy in Chile and a geographically targeted subsidy in Colombia--shows that the means-tested system is better able to identify poor households than the geographically ...
-
(Taylor & Fracis, 2020)Using a statistical approach, Scheihing attempts to demonstrate the direct influence of recharge events in the Precordillera and the Andean Piedmont on water table variations in downstream alluvial fans. The author ...
-
(Academic Press, 2019)In the hyperarid Atacama Desert (Northern Chile), the economic and social development is supported using fossil groundwater. The groundwater extraction (GWE)has significantly increased over the last 30 years, reaching ∼4.2 ...
-
(Elsevier, 2018-07-15)In this work, Ag and Ni metals incorporation effect on the water adsorption and physicochemical properties of 5A zeolite was studied. For that, Ag/5A and Ni/5A zeolites with different amounts of metal (4, 10 and 20 wt%) ...
-
(The American Astronomical Society, 2013)Water is key in the evolution of protoplanetary disks and the formation of comets and icy/water planets. While high-excitation water lines originating in the hot inner disk have been detected in several T Tauri stars ...

(2002)Ruthenium complexes of the type [RuL(CO)2Cl2], [RuL2Cl2], [RuL2(CO)(H2O)](PF6)2, [RuL2Cl]2(PF6)2, [RuL2(CO)Cl](PF6), and [RuL2(CO3)]·3H2O (where L is a bipyridine or phenanthroline derivative) dissolved in aqueous ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-04)Long chain aliphatic alcohols have been used as model compounds to develop a preparative method for a water-soluble material, which could be a carrier for triacontanol, a highly hydrophobic plant growth regulator. New ...
-
(Springer, 2014)Parasitic illnesses are major causes of human disease and misery worldwide. Among them, both amebiasis and Chagas disease, caused by the protozoan parasites, Entamoeba histolytica and Trypanosoma cruzi, are responsible ...
-
(Elsevier, 2012)A common feature in plants that are exposed to gradual stressful environmental factors is the development of a level of resistance to such constraints, which sometimes protects against different stressful environmental ...
-
(Universidad de Chile, 2015)En este trabajo se aborda el problema de existencia de algunos tipos de soluciones para las ecuaciones de ondas en el agua así como la relación que existe entre estas soluciones y la forma de un fondo impermeable sobre la ...
-
(MDPI, 2021)Given its potentialities and characteristics, energy generation, food production, and water availability have a strong interdependency and correlation. Water is needed to produce energy and food, while energy is required ...
-
(Wiley, 2017)The results of an experimental study on the oxygen transfer across the air-water interface under the combined effect of wind and mechanically generated waves are presented in the paper. The experiments were carried out in ...
-
(American Physical Society, 2020)We report on the enhancement of the hydrodynamic damping of gravity waves at the surface of a fluid layer as they interact with a turbulent vortex flow in a sloshing experiment. Gravity surface waves are excited by oscillating ...
-
(Springer, 2012)The wave friction factor is commonly expressed as a function of the horizontal water particle semi-excursion (Awb) at the top of the boundary layer. Awb, in turn, is normally derived from linear wave theory by UwbTw 2p ...
