Energy Efficient LEACH

International Journal of Computer Applications, 2013
Sensors are battery operated devices and are normally placed in the region where humans could not reach easily. Therefore these devices need to be used carefully so as to extend the network life. Network layer plays important role for transmission of data from source node to destination node.

Review of key causes and sources for N2O emmisions and NO3-leaching from organic arable crop rotations [PDF]

, 2018
. The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) have considerable negative impacts on climate and the environment. Although these environmental burdens are on average less per unit area in organic than in non-organic production, they

Enhanced Recovery of Zn from Carbonate-Type Mixed Oxidized Ore (CMO) by Combining Organic Acid Leaching with Mechanical Activation

Metals, 2023
With excessive consumption of sulfide ores, using low-grade Pb-Zn mixed ores to obtain Zn has attracted more attention. Acid leaching is an effective method for Zn recovery; however, a high concentration of inorganic acid brings severe environmental ...
