This paper presents the results of testing certain remote sensing indices (vegetation health index, temperature index, normalized drought difference index, and others).Multitemporal data of nine indices from Sentinel-2 and MODIS satellites for the vegetation period over 5 years were used to simulate the spring wheat yield of the Experimental farm o
This work is concerned with the chemical profile of Taxodium distichum winter cones.The extract obtained after maceration in absolute ethanol was subjected to qualitative analysis by gas chromatography/mass spectrometry and quantification was done by gas chromatography/ flame ionization detector.The chromatogram revealed the presence of 53 compound
Firstly, design basis and principle of NDJ3 low profile barn door kit diesel locomotive electric drive system was represented.Secondly, the main drive system, excitation system, power-supply system and control & protection system were introduced, emphasis on the improvement based on existing technology including brake design, fire-alarm design, ope
The stress path characteristics of surrounding rock in the formation of gob were analyzed and the unloading was solved.Taking Chengchao Iron Mine as the engineering background, the model for analyzing the instability of deep gob was established based on the mechanism of stress relief in deep mining.The energy evolution law was analyzed by introduci
