the hydrological regime there is unpredictable for aquatic organisms, the physical and chemical parameters of water and the content of biogenic elements are much more variable, and therefore, the feed base is unstable. Therefore, reservoirs provide significant advantages to alien species over native spe...

But in the end, when the sky went dark over Tenochtitlan, and the earth shook beneath the feet of Montezuma, it was not the sun god who brought judgment; it was the Conquistadors. The Spaniards’ military advantages over the Aztecs—the swords, guns, and horses–were nullified in the ...
This hybridization integrates the advantages of both methods [64]. First, regarding constraints 1 to 23, algorithm randomly generates the initial population PtPt, including 200 individuals. As earlier discussed in Section 4.5, this problem consists of 10 independent variables; therefore, each ...
Hence, in this work a QuEChERS approach was chosen to extract the 16 PAHs, 4 nitro-PAHs and 14 PCBs from tomatoes due to its typical advantages, such as simplicity, low amount of organic solvent required and low time consumed [40]. The optimization strategy followed: (1) a first ...
Among several advantages are a better control of plant nutrition, a more efficient use of space, the avoidance of herbicide and reduction of pesticide use, and fertilizer and water savings. Hydroponics also assures a more precise control of growth conditions such as lighting, humidity, and ...
