During the construction of nuclear waste storage facilities, deep drilling, and geothermal energy development, high-temperature rocks are inevitably subjected to thermal shock. The physical mechanical behaviors granite treated with different shocks were analyzed by non-destructive (P-wave velocity test) destructive tests (uniaxial compression test Brazil splitting test). results show that P-wav...

Results Sixty-six different patients, median age 69 years (25-87). Most common origins were central catheter in 22 (31%), lung in 15 (21%) and abdomen in 10 (14%). Gram-negative bacteria alone caused 32 cases (46%, Pseudomonas and Enterobacter were predominant, with 15 cases of MRB), Gram-positive 29 (41%, coagulase-negative staphylococci was the most common), fungi in 9% and mixed origin in 4%...

Dihydroxylammonium 5,5′-bis(tetrazole)-1,1′-diolate (TKX-50) is a newly synthesized energetic material with high energy storage, low impact sensitivity, and low toxicity. These features make it a viable candidate to replace such commonly used energetic materials as RDX and CL-20 in the next generation of explosives. Sensitivity determines the engineering application of energetic materials (EMs)...

BACKGROUND The evaluation of fluid responsiveness in patients with hemodynamic instability remains to be challenging. This investigation aimed to determine whether respiratory variation in carotid Doppler peak velocity (ΔCDPV) predicts fluid responsiveness in patients with septic shock and lung protective mechanical ventilation with a tidal volume of 6 ml/kg. METHODS We performed a prospectiv...

This manuscript presents a method to calculate and analyze mechanical shock of multi-rigid body system, based on the revised concept center percussion newly derived variable called radius percussion. The objective is improve mechanism’s robustness against shocks that are caused by certain impacts, such as those experienced legged robots from landing jump or making step. In practice, it can be u...
