A Preliminary Study on the Genesis of De Broglie Wave

Yicheng Chen
As for DE Broglie’s hypothesis of matter waves, many experimental physi-cists have experimentally verified it by using cathode ray tube and proved that matter waves do exist, so there is a mysterious hypothesis of wave-particle duality. In this paper, according to the electric field force of electrons in the cathode ray tube and the continuity equation of electrons, Under assumptions such as inelastic approximation, it is proved that the wave-particle duality is actually the macroscopic motion o...

Research on Water Quality Parameter Prediction Model Based on TCN

Hang Yang,Xiaoqi Yin,Li Hong,Kun Jiang,Xingyu Zhang
Water quality parameter prediction is a new water quality detection tech-nology in the era of big data, which plays a vital role in the management and protection of water resources. Traditional water quality parameter pre-diction models such as RNN and LSTM have low accuracy and cannot provide scientific basis for water environment management effectively. This paper takes the water quality parameters of Subei irrigation canal in Huaian as the research object, analyzes and compares three predicti...

Production and Characterization of Keratinase Enzyme from Natural Isolate Bacillus Strains

Aboubacar Sidiki Dansoko
Bacillus sp is microorganism’s species which can produce keratinase enzyme.The enzyme has ability to degrade keratine substrate and it belongs to extraceluler inducible enzyme group. In this study, proteolitic activities of Bacillus strains isolated from soil contaminated with poultry farm waste were determined on Skim milk Agar. 63 Bacillus strains were identified as proteolytic. Nine of these strains showed activity with the keratin-azure substrate and were determined to be keratinolytic. Amon...
