TDs are classified according to their operating status: active (Figs.3,4), abandoned (Figs.5,6) and restored (Fig.5, Table S-1). In addition, some tailings are discharged as they leave the flotation process and are separated by gravity when flowing inside the TD basins, while other tail...
The frequency of these concepts may indicate that these ideas are foundational as introductory students construct knowledge about FEW systems. Many of the most common codes could be classified as demonstrating basic knowledge, which is the simplest cognitive task presented in Bloom’s taxonomy model (...
open-ended questions) are used for assessing interdisciplinary connections because student thinking and reasoning are more explicit compared to multiple choice type questions; however, these CR assessment items are challenging and time-consuming to design and grade. One...
Local materials are typically used, and this explains the high added value of hydropower to local economies. Concrete is used for dams, civil works and infrastructures, including the powerhouse. In large-scale high-head hydropower plants, concrete may also be used in the construction of intakes,...
I don’t see this decision as a real obstacle to your inclination: like me, you surely think and, above all, see that worries and calculations about one’s professional position are ridiculous dams against the outburst of passions” Differently from the cases discussed previously, this kind of...
Treatment Treatment of aspergillosis may be classified in empirical, preemptive and definitive. Empirical treatment is the one administered to neutropenic patients at risk with a prolonged febrile period, who have already received broad antibiotic coverage. Preemptive therapy is the one administered when...
Water from reservoirs accounts for 30–40% of global irrigation and supports 12–16% of the world's food production [World Commission on Dams, 2000; Lehner et al., 2011]. Recently, reservoirs have also received increased attention for their relevance to pressing environmental issues such as ...
The regulation of water by river dams since the 1960s has fundamentally changed the natural run-off of the Syr Darya, resulting in reduced water quantities during the vegetation season. Additionally, after the independence of the bordering countries, energy production from the dams during the ...
Water absorbs the sun’s radiation joules and turns them into gravitational potential energy joules when it evaporates and then kinetic energy joules when it rains and slides down land, and humans saw the opportunity to snatch some of those up by creating water wheels or dams. But the most ...
