Dagh-Dali Zn-Pb deposit is located 40 km north of Takab city and it consist of Bekhair-Bolaghi and Baldirghani ore zones.Mineralization in Bekhair-Bolaghi is consist of galena, sphalerite, pyrite and chalcopyrite with disseminated texture hosted in the Kahar shales and Jangotaran dolomitized limestone.Sphalerite is mainly associated with galena or
In light of the difficulty of solid-liquid separation of waste PEM drilling fluid in the Bohai oilfield, constructing an inorganic-organic flocculation system is proposed and the processing method of destabilization technology is optimized.The biggest influence factor on the flocculation process of PEM drilling fluid was determined by designing an
Abstract Introduction Male gender is an important risk factor of central serous chorioretinopathy (CSC), and studies have explored the pathophysiological role of androgens in CSC with conflicting results.Text Clustering Algorithm Based on Random Cluster Core.In this study, we shed light on this hot topic by exploring the risk of CSC in a large coho
Double-unit trains increase passenger capacity but also increase energy consumption.Therefore, research about the aerodynamic resistance of a double-unit train is of great importance to save energy.In this study, a commercial long-marshalling high-speed train and 8 kinds of double-unit trains are used to investigate the effect of the gap length on
Fungal endophytes play a pivotal role in tropical forest dynamics, influencing plant fitness through growth stimulation, disease suppression, stress tolerance, and nutrient mobilization.This study investigates the effects of region, leaf developmental stage, and tissue type on endophyte communities in tropical plants.Young and mature leaves were co
