(Blackwell Publishing Ltd, 2019)© 2018 The Authors. Journal of Applied Ecology © 2018 British Ecological SocietyThe global trade of species promotes diverse human activities but also facilitates the introduction of potentially invasive species into new ...
-
(Springer, 2011-01)Inspections represent key activities in construction projects. They allow coordinating the work of the main contractor and the subcontracted companies participating in the project. Today the inspection activities and the ...
-
(Elsevier, 2017)The notion of developing a transnational offshore grid in the North Sea has attracted considerable attention in the past years due to its potential for substantial capital savings and increased scope for cross-border trade, ...
-
(CEUR-WS, 2017)In order to minimize the accidents, autonomous vehicles are being designed as the future of transportation. To fulfill this goal, we should look at vehicular intersections, where unfortunately most car accidents take place. ...
-
(Institute of Electrical and Electronics Engineers Inc., 2018)This paper studies key aspects of preventive and corrective security strategies to coordinate flexible transmission network infrastructure. To do so, we propose a two-stage stochastic optimization model that can efficiently ...

-
(Electrochemical Soc, 2016)Impurities and additives play a key role in copper electrodeposition, in particular in upstream processes such as electrowinning or electrorefining. One common impurity is iron, mostly present as iron species Fe(II) in ...
-
(CENIM, 2008-04)A two-compartment lab,scale reactive electrodialysis (RED) cell with a moving particulate cathode has been used for copper electrowinning. The cathodic reaction was copper electrodeposition on a bed of copper particles ...
-
(Elsevier, 2020)Extracting copper is energy-intensive. At the same time, copper is a key material for building the energy systems of the future. Both facts call for clean copper production. The present work addresses the greenhouse gas ...
-
(Elsevier, 2011)Copper nanoparticles with sizes between 10nm and 50nm were grown by condensation in hydrogen at pressures from 10 Pa to 1200 Pa. The crystallite size ranged from 10nm to 25nm using the Scherrer method. X-ray diffraction ...
-
(Elsevier, 2014)A bio-rack system was developed for treating Cu-contaminated freshwaters. Each pilot constructed wet-land (CW, 110 dm3) contained 15 perforated vertical pipes filled with a mixture of gravel (diorite; 80%)and perlite (20%) ...
-
(AMER CHEMICAL SOC, 2007-08)Two new ligands, 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenol (HL) and 2-[(bis(2-pyridylmethyl)amino)methyl]- 4-methyl-6-(methylthio)phenol (HSL), were synthesized and were used to prepare the trinuclear copper(II) ...
-
(Elsevier, 2017-05-01)Over the past few decades several studies have reported that pyrite hosts appreciable amounts of trace elements which commonly occur forming complex zoning patterns within a single mineral grain. These chemical zonations ...
-
(MDPI, 2021)In the last decades, the incorporation of copper in polymeric membranes for water treatment has received greater attention, as an innovative potential solution against biofouling formation on membranes, as well as, by its ...
-
(ELSEVIER, 2008-06-01)Copula modeling has become an increasingly popular tool in finance to model assets returns dependency. In essence, copulas enable us to extract the dependence structure from the joint distribution function of a set of ...
-
Cordierite-bearing granitic rocks in South America: Contrasting sources and conditions of formation (Elsevier Ltd, 2019)Mineralogy, geochemistry and isotopic data for Ediacaran, Ordovician to Devonian, and Upper Triassic cordierite-bearing granitoids respectively from Brazil, Argentina and Chile are discussed here. Syn-collisional Lower to ...

(Oxford Univ Press, 2015)We report long-slit spectroscopic observations of the quasar SDSS J082303.22+052907.6 (z(C IV) similar to 3.1875), whose broad-line region (BLR) is partly eclipsed by a strong damped Lyman alpha (DLA; logN(H I) = 21.7) ...
