(Emerald, 2020)Purpose - This paper aims to present a comprehensive perspective on how tribology and sustainability are related and intertwined and are linked to CO2 emissions. This paper emphasizes on how tribological aspects affect ...
-
(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 ...
