(Springer Verlag, 2019)© 2019, Springer-Verlag GmbH Germany, part of Springer Nature.This paper proposes and validates a thermo-mechanical ratcheting mechanism that explains the cumulative displacement of soil–continuum interfaces when subjected ...

(International Solar Energy Society, 2020)
-
(Nature, 2015)The laws of thermodynamics put limits to the efficiencies of thermal machines. Analogues of these laws are now established for quantum engines weakly and passively coupled to the environment providing a framework to find ...
-
(EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2004-01)The partition function of a dilute Bose gas with repulsive interaction, fixed number of particles and in the presence of a condensate is computed up to first order in the interactions. An equilibrium condition appears for ...
-
(Elsevier, 2017)A thermoeconomic assessment of the joint production of electricity, fresh-water, cooling and heat for a solar polygeneration plant is carried out. The aims are to assess the actual cost of each product, to conduct a ...
-
(Elsevier, 2020)The south-central Chile margin experienced the largest and sixth largest earthquakes ever recorded - the 1960 Mw 9.5 Valdivia and 2010 Mw 8.8 Maule megathrust earthquakes, respectively. In early 2017, we conducted a seismic ...
-
(IOP Publishing, 2015)In the third Galactic quadrant (180 degrees <= l <= 270 degrees) of the Milky Way, the Galactic thin disk exhibits a significant warp-shown both by gas and young stars-bending down a few kiloparsecs below the formal Galactic ...
-
(Springer Netherlands, 2019)Thinning is an agronomic practice that consists in the removal of a certain number of fruits, thereby altering the source–sink equilibrium in the tree and favoring carbon allocation to the remaining fruits. If thinning is ...
-
(Elsevier Doyma, 2019)© 2018 Asociación Española de PediatríaIn a world that is increasingly technological and interconnected, but also more violent, overexploited and polluted, Paediatric Environmental Health (PEH) is one of the best contributions ...
-
(ESO, 2005)Three nearby star candidates were selected as bright 2MASS point sources without associated optical sources, i.e. with potentially large proper motions, subsequently confirmed by multi-epoch optical data from the SuperCOSMOS ...
-
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)In this paper we present distributed property-testing algorithms for graph properties in thecongestmodel, with emphasis on testing subgraph-freeness. Testing a graph propertyPmeansdistinguishing graphsG= (V,E)having ...
-
(ESO, 2014)For the past six years we have carried out a search for massive planets around main sequence and evolved stars in the open cluster M67, using radial velocity (RV) measurements obtained with HARPS at ESO (La Silla), SOPHIE ...
-
(EDP Science, 2020)We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is an ultra-short-period Jupiter orbiting a ...
-
(AMER GEOPHYSICAL UNION, 2006-09-26)We forward modeled the Bouguer anomaly in a region encompassing the Pacific Ocean (85 degrees W) and the Andean margin (60 degrees W) between northern Peru (5 degrees S) and Patagonia (45 degrees S). The three-dimensional ...
-
(Taylor and Francis Ltd., 2018)The stability graph method is widely used for open stope mine design. During the development of the method the effect of induced stresses were included by using two-dimensional or limited three-dimensional stress analysis. ...
-
(Oxford University Press, 2016)We use seismic tomography to investigate the state of the supraslab mantle beneath northern Chile, a part of the Nazca-South America Plate boundary known for frequent megathrust earthquakes and active volcanism. We performed ...
-
(Elsevier, 2016)Magnetotelluric (MT) data were recorded to investigate a geothermal prospect in northern Chile. The exploration area is located in the Atacama region, at the southern edge of the Chilean Altiplano, at an altitude of similar ...
-
(IOP Publishing, 2020)Offsets of molecular line emission peaks from continuum peaks are very common but frequently difficult to explain with a single spherical cloud chemical model. We propose that the spatial projection effects of an irregular ...
-
(Amer Geophysical Union, 2015)Lazufre volcanic center, located in the central Andes, is recently undergoing an episode of uplift, conforming one of the most extensive deforming volcanic systems worldwide, but its magmatic system and its connection with ...
-
(Oxford University Press, 2020)The inner parsec of our Galaxy contains tens of Wolf-Rayet stars whose powerful outflows are constantly interacting while filling the region with hot, diffuse plasma. Theoretical models have shown that, in some cases, the ...
