(Sage, 2020)Tributary-junction alluvial fans situated at the intersection of confined valleys with <100 km(2) tributary catchments are of special interest to evaluate the heterogeneous consequences of extreme rainfall events in arid ...
-
(EDP Sciences, 2017)Aims. We perform a multiwavelength analysis of the bubble HII region Sh2-39 (N5) and its environs with the aim of studying the physical properties of Galactic IR bubbles and exploring their impact in triggering massive ...
-
(IOP Publishing, 2016)We observed occultations by Pluto during a predicted series of events in 2014 July with the 1 m telescope of the Mt. John Observatory in New Zealand. The predictions were based on updated astrometry obtained in the previous ...
-
(Society of Economic Geologists, USA, 2020)The Plio-Pleistocene El Laco iron oxide-apatite (IOA) orebodies in northern Chile are some of the most enigmatic mineral deposits on Earth, interpreted to have formed as lava flows or by hydrothermal replacement, two ...
-
(2003-04-20)We report the discovery, made using the Australia Telescope Compact Array, of a triple radio source toward IRAS 16547 4247, a luminous infrared source with a bolometric luminosity of 6:2 104 L . The radio source shows ...
-
(ELSEVIER, 2006-12-15)Reaction of complex CrCl3 (THF)(3) with the tris(pyrazolyl)methane ligands, HC(Pz)(3), HC(3,5-Me(2)Pz)(3) and their substituted derivatives RC(Pz)(3) (R = Me, CH2OH, CH2OSO2Me) in THF lead to the formation of neutral ...

(Frontiers Media, 2020)17 beta-estradiol is a neuronal survival factor against oxidative stress that triggers its protective effect even in the absence of classical estrogen receptors. The polymodal transient receptor potential vanilloid subtype ...
-
(Polymat, 2020)We study properties of truncations in the dual and intertwining process in the monotone case. The main properties are stated for the time-reversed process and the time of absorption of the truncated intertwining process.
-
(Elsevier, 2017)This paper studies which social networks maximize trust and welfare when agreements are implicitly enforced. We study a repeated trust game in which trading opportunities arise exogenously and a social network determines ...
-
(Society for Industrial and Applied Mathematics, 2015)After a sequence of improvements Boyd et al. [TSP on cubic and subcubic graphs, Integer Programming and Combinatorial Optimization, Lecture Notes in Comput. Sci. 6655, Springer, Heidelberg, 2011, pp. 65-77] proved that any ...
-
(2011)We report on the preparation of WO3 nanostructures using tungsten wire and iron wool in a domestic microwave oven. Pure WO3 nanoparticles were octahedral or rhombohedral while iron containing nanoparticles were spheroidal. ...
-
(Elsevier, 2020)Three amphiphilic carbon nanotube-supported Ni catalysts have been prepared and tested regarding their emulsifying properties for the hydrogenation of furfural. The solid catalysts and emulsions were systematically ...
-
(Elsevier, 2014)One of the main difficulties using multi-point statistical (MPS) simulation based on annealing techniques or genetic algorithms concerns the excessive amount of time and memory that must be spent in order to achieve ...
-
(Elsevier, 2020)Water contamination is increasingly an important issue in developing and under developed countries. The main cause of water contaminations are industrial dyes and toxic chemicals. Hence many technologies are being developed ...
