(MDPI AG, 2019)Little research has been done to evaluate the occupational health of electronic waste (e-waste) recycling workers in Latin America. The objective of this study was to complete comprehensive health evaluations on e-waste ...
-
(EMERALD GROUP PUBLISHING LIMITED, 2008)Purpose – The purpose of this paper is to propose, from the way in which an allopathic physician makes a diagnosis of a person’s health, an organizational diagnosis metaphor that can contribute in the search for an ...

Heat and dissolved oxygen exchanges between the sediment and water column in a shallow salty lagoon (American Geophysical Union, 2014)Dissolved oxygen (DO) and heat exchanges across the water-sediment interface (WSI) of a shallow lagoon are controlled by processes occurring on both sides of the WSI, particularly volumetric source and sink on the sediment ...

(2007)Natural convection of air in a cubical enclosure with a thick partition fitted vertically on the hot wall is numerically investigated for Rayleigh numbers of 10(3)-10(6). A three dimensional convective circulation is ...
-
(Elsevier Ltd, 2018)The swirl flow minichannel heat sink has shown to be a promising alternative for thermal management of high heat flux applications, such as electronics and concentrated photovoltaics. Effective heat transfer enhancement ...

Heat transfer in an oval tube heat exchanger with different kinds of longitudinal vortex generators (American Society of Thermal and Fluids Engineers, 2017)A numerical study was performed on a plate fi n and oval tube heat exchanger with diff erent kinds of longitudinal vortex generators (LVG). The infl uence of LVG on heat transfer and pressure drop is investigated, and ...
-
(MDPI AG, 2019)In mineral processing, the common requirement for progressively finer milling due to the decreasing of ore grades implies the need for more challenging water recovery conditions in thickeners. Several mining operations ...
-
(MDPI, 2022)Comminution is the stage with the largest energy consumption in the mining process. Therefore, several pre-treatments have been proposed to reduce the energy requirements of this stage. This work analyzed the effect of a ...
-
(Sociedad Chilena de Quimica, 2018)Northern Chile is characterized by water scarcity. The Lluta River, located in the XV region of Arica and Parinacota, is the one of the main rivers in northern Chile. The elevated levels of metals and metaloids in the ...

(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-08)Given a number field K and a subgroup G ⊂ K ∗ of the multiplicative group of K, Silverman defined the G-height H(θ;G) of an algebraic number θ as H(θ;G) := inf g∈G, n∈N H g1/nθ , where H on the right is ...
-
(Springer, 2016)Helical flow can occur in porous media if the hydraulic conductivity tensor is anisotropic.We study the structure of steady-state flowfields in three-dimensional anisotropic porous media formed by two homogeneous layers, ...
-
(Universidad de Concepcion, 2019)Ants present hermetism, that is, they recognize and discriminate individuals alien to the colony, even at a homospecific level, which results in aggressive reactions against intruders, varying with their age. To evaluate ...
-
(1993)we consider a quadratic eigenvalue problem such that the second order term is a Hermitian matrix of rank r, the linear term is the identity matrix, and the constant term is an arbitrary Hermitian matrix A E cnn. Of the ...
-
(IOP Publishing, 2015)We present similar to 2; x 2' spectral-maps of Orion Becklin-Neugebauer/Kleinmann-Low (BN/KL) outflows taken with Herschel at similar to 12 '' resolution. For the first time in the far-IR domain, we spatially resolve the ...
-
(EDP SCIENCES S A., 2010-07)The HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE) of the Magellanic Clouds will use dust emission to investigate the life cycle of matter in both the Large and Small Magellanic Clouds (LMC and SMC). Using ...
-
(The American Astronomical Society, 2013)We present an overview of the HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE) in the Magellanic Clouds project, which is a Herschel Space Observatory open time key program. We mapped the Large Magellanic ...
-
(EDP Sciences, 2013)We present results of far-infrared photometric observations with Herschel PACS of a sample of Upper Scorpius stars, with a detection rate of previously known disk-bearing K and M stars at 70, 100, and 160 μm of 71%, 56%, ...
