Drip irrigation is the most effective and reliable method for reclaimed water irrigation. Emitter clogging is the bottleneck to restrain the application and popularization of reclaimed water drip irrigation technology, and some researchers have reported that this was tightly related to the formation of biofilms in the irrigation system. We selected(More)
BACKGROUND Disaster Medicine training is not included in medical education curriculum in China, even though the country has suffered various disasters annually. We intended to assess the need for continual education regarding disaster management for health professionals in China. METHODS A survey was conducted among 324 health professionals who(More)
Drip irrigation is the most effective and reliable method for reclaimed water irrigation. The water usually contains a lot of suspended particles, metal salt ions, organisms and microbial communities, which will enhance the possibility of emitter clogging or more complex clogging mechanism. Emitter clogging has become one of  the key problems to the(More)
Emitter clogging is a bottleneck to restrain the application and popularization of reclaimed water drip irrigation technology, and it is tightly related to the formation of biofilms attached on drip irrigation emitters. However, there is still no quantitative description about the relationship between biofilms components and emitter clogging. Based on the(More)
Er doped GaN (GaN:Er) p-in structures were prepared by metal organic chemical vapor deposition. Effects of growth pressure on the optical performance of GaN:Er p-in structures have been investigated. Electroluminescence measurements revealed that the optimal growth pressure window for obtaining strong infrared emission intensity at 1.54 µm is around 20(More)
Emitter clogging has become one of the main restrictions in the development of drip irrigation with reclaimed water. Numerous studies have found that emitter clogging is closely related to the formation and growth of biofilms attached within the emitter wall, raising the question of how to effectively control the formation of biofilms, which is the key to(More)
Drip irrigation frequency has important impacts on crop growth, soil moisture, nutrient, salinity and substances’ accumulation in the irrigation system as well as drip irrigation emitter clogging. However, previous studies on reasonable drip irrigation frequency merely focused on crop yield and quality, soil water and salinity transporting, neglecting its(More)
