gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
introduction: providing the nutritional requirements of agricultural crops by non-chemical resources is a new approach in the organic farming that has attracted the attention of both the researchers and the consumers in recent years. therefore, it is highly important to find new fertilizer resources that are both economically able to provide the nutritional needs of the crop plants and have no ...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
KamLAND measured the ν̄ e's flux from distant nuclear reactors, and found fewer events than expected from standard assumptions about ν̄ e propagation at the 99.998% confidence level (C.L.). The observed energy spectrum disagrees with the expected spectral shape at 99.6% C.L., and prefers the distortion from neutrino oscillation effects. A two-flavor oscillation analysis of the data from KamLAND a...
in recent years, heavy metal contamination of rice in different parts of the world has raised concerns about its safety and provoked crisis in it's global production and trade. in iran, also some studies have reported on the heavy metal contamination of native products. however, the concentration of heavy metals in rice grain could be influenced through preparation and cooking. this study aimed...
Swordfish (Xiphias gladius L., 1758) is an apex predator, highly migratory meso-pelagic fish widely distributed in the Atlantic Ocean and Mediterranean. As top predators, this fish may be the end reservoir of the bioaccumulation of trace elements in a food chain because they occupy higher trophic levels and are an important food source, causing them to be potentially hazardous to consume. This ...
Psychological inflexibility and mindfulness represent two constructs that have garnered a great deal of interest in recent years as central components in the conceptualizati on of many new cognitive and behavioral therapies. Nonetheless, though theoretically related, relatively little is known regarding associations between these two constructs and consensus models of trait personality such as ...
