A COMPARISON OF SUCRALFATE AND RANITIDINE FOR THE PREVENTION OF UPPER GASTROINTESTINAL BLEEDING IN PATIENTS REQUIRING MECHANICAL VENTILATION
A BSTRACT Background Critically ill patients who require mechanical ventilation are at increased risk for gastrointestinal bleeding from stress ulcers. There are conflicting data on the effect ofExpand
The harmonic state of quantum cascade lasers: origin, control, and prospective applications [Invited]
The recently discovered ability of the quantum cascade laser to produce a harmonic frequency comb has attracted new interest in these devices for both applications and fundamental laser physics. InExpand
Core / shell nanofiber characterization by Raman scanning microscopy
Core/shell nanofibers are becoming increasingly popular for applications in tissue engineering. Nanofibers alone provide surface topography and increased surface area that promote cellularExpand
FOUR BRILLIANTLY COLORED AFRICAN REED FROG SPECIES (HYPEROLIIDAE: HYPEROLIUS)
—The sequestration of alkaloids from prey items for the purpose of chemical defense has evolved independently in five frog families, and is documented for approximately 150 taxa. The number ofExpand
Ultrafast modulation of the spectral filtering properties of a THz metasurface
We demonstrate ultrafast tuning of a plasmonic spectral filter at terahertz (THz) frequencies. The device is made of periodically spaced gold crosses deposited on the surface of an undoped siliconExpand
Active phase control of terahertz pulses using a dynamic waveguide
Control over the spectral phase of a light pulse is a fundamental step toward arbitrary signal generation in a spectral band. For the terahertz spectral regime, pulse shaping holds the key forExpand
ADOPTION OF RAISED BED TECHNOLOGY IN SOME SELECTED LOCATIONS OF RAJSHAHI DISTRICT OF BANGLADESH
The study evaluated the adoption and farmers’ practice of raised bed technology at farm level since the close of the Soil Management Collaborative Research Support Program (SMCRSP) through aExpand
