Blast-induced ground vibration is one of the inevitable outcomes of blasting in mining projects and may cause substantial damage to rock mass as well as nearby
A sensitive, accurate and selective liquid chromatography-tandem mass spectrometry method (LC-MS/MS) was developed and validated for the simultaneous quantitati
A selective, sensitive and high throughput liquid chromatography-tandem mass spectro-metry (LC-ESI-MS/MS) method has been developed for separation and quantific
In this paper,a new pill-box window with arc groove disk is studied for S-band high power klystron.Its main characteristics are long pill-box and periodic groov
