➤ Although there is some evidence that scrubs, masks, and head coverings reduce bacterial counts in the operating room, there is no evidence that these measures reduce the prevalence of surgical site infection.➤ The use of gloves and impervious surgical gowns in the operating room reduces the prevalence of surgical site infection.➤ Operating-room ventilation plays an unclear role in the prevent...

Recently, there has been an increasing interest in the LIBS (Laser-Induced Breakdown Spectroscopy) technique for stand-off detection of geological samples for use on landers and rovers to Mars, and for other space applications. For space missions, LIBS analysis capabilities must be investigated and instrumental development is required to take into account constraints such as size, weight, power...

Recent progress in atom interferometry has lead to a new way to map and monitor the Earth gravity field. Atom interferometer-based instruments may significantly contribute to the understanding of the solid earth, ice and oceans, and dynamic processes in a comprehensive model of our planet. We are funded under the Advanced Technology Component program to develop this technology for a possible fl...
