a considerable amount of energy is released in the form of shock wave from explosive charge detonation. shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. the rest of the shock wave energy is transferred to rock mass as ground vibration. ground vibration is conveyed to the adjacent structures by body and surface waves. geological structures li...

METHODS Fasting blood samples were obtained on 165 people living with HIV at baseline and after 24 weeks on highly active antiretroviral therapy (HAART). Participants were classi...

Coupled-channel, multiresonance partial wave analysis (PWA), developed and used by Carnegie-Mellon-Berkeley analyses group (CMU-LBL 79) 1 has been recently very frequently used, and agreed as a potentially safe tool for extracting N * resonance parameters 2,3,4,5. The newly formed subsection for resonance parameter analyses of Baryon Resonance Analysis Group (BRAG) 6 has decided to re-evaluate ...
