To overcome these difficulties, we have applied several well-known popular metaheuristic algorithms (Water Cycle Algorithm (WCA), Artificial Electric Field Algorithm (AEFA), Teaching Learning Based Optimization Algorithm (TLBOA), Grey Wolf Optimizer Algorithm (GWOA), Sparrow Search Algorithm (SSA), ...
While significant parts of the globe are already facing significant freshwater scarcity, the need for more freshwater is projected to increase in order to sustain the increasing global population and economic growth, and adapt to climate change. Current approaches for addressing this challenge, which ...
biosorbent against a nickel concentration of 0.9 ppm increased from 92% in the first cycle to almost 99% in the second and third cycles. This behavior was attributed to the slight increase of the biosorbent's negative zeta potential after being recycled using hydrochloric acid, resulting in impro...
Comparing life cycle costs of water services among several low, medium and high-income utilities Universal access to safe drinking water will require an investment of over $140 billion in capital expenditures to meet the targets set by the United Natio... MTE Libey - 《World Development》 被引...
Reservoirs are a globally significant source of methane (CH4) to the atmosphere. However, emission rate estimates may be biased low due to inadequate monitoring during brief periods of elevated emission rates (that is, hot moments). Here we investigate CH4bubbling (that is, ebullition) during per...
The sulphate content of deep granite groundwaters is, however, variable and a simple explanation for its origin and behaviour remains elusive in many cases (Fontes et al., 1989). Sulphate could conceivably be derived from one or more of the following sources: These hypotheses are very similar ...
bioassays with data providing information on select endocrine mechanisms of action; while level 4 and 5 are in vivo assays providing data on adverse effects on endocrine-relevant endpoints, with level 5 consisting of bioassays over more extensive parts of the organisms life cycle compared to level ...
Directive 2008/56/EC). In the Elbe river catchment, aspects of policy and science are closely connected, which became particularly obvious in a classic example of dioxin hot spot contamination, the case of the Spittelwasser creek. Here, the “source-first principle” of the first cycle of ...
41b), where the decrease in bond strength each cycle could be attributed to the low chain mobility of the polymers during the brief (3 s) re-dissolution step and potential oxidation when the polymers were exposed to the air. Still, even after 4 cycles, adhered aluminum rods could still...
glass impeller. After the hydrolysis, the diluted acid solution was quenched with ca. 500 g of cold DI water and the CNCs were isolated from the acid by three successive centrifugations (15 min each cycle, ca. 30 000g), before they were redispersed in 600 mL of DI water and...
