BACKGROUND To identify and analyze factors that influence the grading and zoning management model of emergency triage as a first step in the improvement of the system. METHODS Questionnaires were used to extract data from clinical histories of 286 patients who attended the Emergency Department of Binzhou Central Hospital (Binzhou City, Shandong Province, China) from September to November of 2...

Time-lapse (4D) seismic data sets have proven to be extremely useful for reservoir monitoring. Seismic-derived impedance estimates are commonly used as a 4D attribute to constrain updates to reservoir fluid flow models. However, 4D seismic estimates of P-wave impedance can contain significant errors associated with the effects of seismic noise and the inherent instability of inverse methods. Th...

Assessment of local seismicity caused by human engineering activity is a necessity after several earthquakes have been recorded in world practice, which destroyed hydraulic structure, dam and accompanied casualties. The Tupalang, Gissarak Pachkamar reservoirs, operated southern Uzbekistan, are located the mountain system part Tien Shan seismogenic fault. According to general seismic zoning, zon...

BACKGROUND Zoning is a fundamental tool for the effective management of nature reserves. A three-zone model (core zone, buffer zone, and experimental zone) has been applied to nature reserves in China since 1980s; however, this model appears not fit for all types of nature reserves, especially wetlands. CASE DESCRIPTION Wuliangsuhai is such a typical wetland reserve, which can represent most ...

Coda-wave interferometry is a technique to detect small seismic velocity changes using phase changes in similar waveforms from repeating natural or artificial sources. Seismic interferometry is another technique for detecting seismic velocity changes from cross-correlation functions of ambient seismic noise. We simultaneously use these two techniques to clarify seismic velocity changes at Sakur...
