The fraction of delayed neutrons in a moderated beam from the enriched uranium, pulsed spallation source at the intense pulsed neutron source at Argonne National Laboratory has been measured and found to be 0.0283 for 450-MeV protons. Delayed neutrons produce a sample-dependent background in time-of-flight instruments . Because of the distribution of neutron wavelengths in the prompt pulse, the...

The objective of this study was to investigate the effect of routine dental occlusal equilibration treatment on dressage horse performance. Sixteen horses (11 treated; 5 untreated) ridden by a single rider performed a standardized dressage test twice and were scored by two experienced dressage judges according to recognized movements and rider cues. All horses were sedated and a full-mouth spec...

Robotic surgery is an exciting technology that allows the surgeon to sit at a computer console near the operating table, using mechanical arms with surgical instruments attached to them. This type of surgery is minimally invasive, and the procedure is performed through tiny incisions. This technology is widely used in the United States and is expected to evolve over time with an increase in the...

This study aims to understand how firms in developing countries can effectively use their Information System (IS) resources to develop valuable e-collaboration capabilities that in turn improve business performance. A questionnaire-based survey was conducted to collect data from 408 Iranian and Malaysian manufacturing firms. Findings revealed that Supply Chain-Wide Process Integration (SCPI) an...

➤ 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...
