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 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 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)
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)
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)
Emitter clogging has a direct impact on the required operating time and benefit of a drip irrigation system, especially when using reclaimed water. Thus, accurately evaluating its anti-clogging ability is important to select an appropriate emitter under specific conditions. In his paper, a drip irrigation emitter clogging experiment was carried out, and the(More)
The objective of this study is to evaluate impacts of different management scenarios for American lobster (Homarus americanus) and Atlantic cod (Gadus morhua) fisheries on the dynamics of ecosystem for the lobster in the Gulf of Maine (GOM). The GOM lobster supports one of the most economically valuable commercial fisheries in the northeastern United(More)
Keeping water eco-environment health and virtuous circle of lake-wetland, and letting lakes recuperate and reproduce has become a common view all over the world. Although a great deal of research results were obtained, such as lake-wetland ecosystem management and eco-hydrological mechanism of eco-environment evolution, there are few researches about(More)
