The burning characteristics of 3 m to 6 m dry Douglas-fir trees Open
A series of experiments are reported on the burning behavior of dry, 3 m to 6 m tall, Douglas fir trees. The measurements were conducted in the open under quasi-quiescent conditions. The global measurements reported include the transient, …

Wind-driven fire spread to a structure from landscape timbers Open
NIST is studying how combustible landscape features around a home burn to better understand their levels of hazard and potential roles in spreading wildland-urban interface (WUI) fires. A series of field experiments was conducted to examin…

Acute appendicitis: A block-randomized study on active observation with or without antibiotic treatment Open
Early antibiotic treatment is superior to traditional "wait and see observation" to avoid surgical exploration and appendectomy.

NIST Outdoor Structure Separation Experiments (NOSSE) with wind Open
The NIST Outdoor Structure Separation Experiments are part of the NIST Structure Separation Experiments project, which is designed to assess structure-to-structure fire spread in the wildland-urban interface. In the first phase of this pro…

Wind-driven fire spread to a structure from firewood piles Open
A series of field experiments was conducted to examine the effects on fire spread toward a structure for firewood piles under conditions that may be encountered in a wildland-urban interface (WUI) fire. The fire behavior of a variety of fi…

Wind-driven fire spread to a structure from fences and mulch Open
A series of field experiments was conducted to examine the effects on fire spread toward a structure for combustible fences and mulch under conditions that may be encountered in a wildland-urban interface (WUI) fire. The fire behavior of a…

NIST Outdoor Structure Separation Experiments (NOSSE) : Open
The Structure Separation Project is a multi-level project to assess structure-to-structure fire spread in Wildland-Urban Interface (WUI) communities. The project is divided into three phases with each phase assessing radiant and convective…

Using photoelectric smoke detection to warn of pre-ignition conditions of unattended cooking fires Open
A series of 21 experiments was conducted to examine the potential to use kitchen-installed photoelectric smoke detection devices to warn of approaching ignition of food during unattended cooking. An electric range, range hood, and cabinets…

Fully covered stents are similar to semi-covered stents with regard to migration in palliative treatment of malignant strictures of the esophagus and gastric cardia: results of a randomized controlled trial Open
In spite of its somewhat lower intrinsic radial force, the fully-covered stent was comparable to the conventional semi-covered stent with regard to stent migration. The data further suggest a potential benefit of the fully-covered stent in…
