Very low frequency (VLF) electromagnetic waves distort along the long propagation path, and that causes the arrival time of the signals measured by the long-range lightning system to be delayed.In this paper, based on the propagation correction method by compensating the peak time delay of the ground wave, the location accuracy of the long-range li

The nacreous layer of shells and pearls is composed of aragonite crystals arranged in an organic matrix.The organic matrix contains chitin and several proteins that regulate the formation of the nacreous layer.Owing to their strong interactions in the organic matrix, the current method for extraction of insoluble proteins from the pre-powdered nacr
