Berdasarkan Permenkes No.492/2010 tentang persyaratan kualitas air minum, merkuri merupakan bahan kimia yang berhubungan dengan kesehatan, sehingga kadar maksimum yang diperbolehkan adalah 0,001000 mg/L.Merkuri memiliki efek berbahaya apabila diatas 0,001000 mg/L.Tujuan penelitian ini adalah untuk mengidentifikasi kadar merkuri pada sampel air minu
The existing seam carving tamper detection Dog Dehydrated algorithms have the problems of low detection accuracy and weak robustness for the case of low scaling factor.A seam carving tamper detection algorithm integrated with hybrid attention mechanism is proposed.Firstly, BayarConv2D constrained convolution is used to preprocess the image, fully l
The 80% ethanol extract of Alstonia yunnanensis afforded Polishing Belt five new monoterpenoid indole alkaloids: 11-hydroxy-6,7-epoxy-8-oxo-vincadifformine (1), 14-chloro-15-hydroxy- vincadifformine (2), perakine N4-oxide (3), raucaffrinoline N4-oxide (4), and vinorine N1,N4-dioxide (5), together with three known compounds: 11-methoxy-6,7-epoxy-8-o
In this paper, numerical and experimental analysis were carried out to study the characters of the detonated rupture disks used in rarefaction wave gun for test.The pressure bearing capacity and cutting blasting ability of the disks were studied in detail.The research results showed that the designed detonated rupture disks could withstand the maxi
