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 ...

(Oxford University Press, 2001)Relative growth rates, basal and acclimated thermotolerance, membrane damage, fluorescence emission, and relative levels of free and conjugated ubiquitin and HSP70 were compared after 2 h of treatment at different temperatures ...
-
(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 Química, 2016)RIVER flows have constant interaction between water and bed sediments; for this reason knowledge of the characteristics of the sediments is fundamental to understand water chemistry. This study determined the concentrations ...
-
(Springer, 2017)In this study, we analyze the concentration of ten metals in two freshwater fish-the benthic catfish Trichomycterus areolatus and the limnetic silverside Basilichthys microlepidotus-in order to detect possible accumulation ...
-
(2013)Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and ...
-
(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 ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)Industrial and domestic waste waters in Chile are discharged without previous treatment into rivers and other inland waters which are used to irrigate agricultural lands. The present study reports on results obtained when ...
-
(1994)The Chilean mine El Teniente is the world's largest underground copper mine. It operates a giant smelter at Caletones (34° 7′ S, 70° 27′ W) and we have found it is the major source of air contamination in the region. In ...
-
(Taylor & Francis, 2018)This paper presents the heavy ordered weighted moving average (HOWMA) operator. It is an aggregation operator that uses the main characteristics of two well-known techniques: the heavy ordered weighted averaging (OWA) and ...
-
(2012)We prospectively identified 96 women consuming at least 4 drinks/day during pregnancy by screening 9628 pregnant women. In these women with heavy prenatal alcohol use, there were three stillbirths and one preterm delivery; ...

(JOHN WILEY & SONS, 2004-09-05)Serotonin (5HT) plays major roles in the physiological regulation of many behavioral processes, including sleep, feeding, and mood, but the genetic mechanisms by which serotonergic neurons arise during development are ...
-
(2004)Stem cells are crucial for normal development and homeostasis, and their misbehavior may be related to the origin of cancer. Progress in these areas has been difficult because the mechanisms regulating stem cell lineages ...
