In order to deal with the huge threat and loss caused by the earthquake, established the evaluation system and model, and the risk zoning map is drawn according to the study of the vulnerability of Xicheng District's streets. According to the spatial coupling relationship between social vulnerability and physical vulnerability, drawn the comprehensive risk zoning map of Shichahai street as a ty...

The effectiveness of 1-epinephrine and 1-norepinephrine in enhancing ventricular vulnerability has l)een compared in twelve dogs by obtaining fibrillation thresholds for single test stimuli. Both agents produce similar increases in vulnerability immediately following injection, and similar decreases in vulnerability at longer intervals following drug administration. These changes in vulnerabili...

This paper establishes a water resources vulnerability framework based on sensitivity, natural resilience and artificial adaptation, through the analyses of the four states of the water system and its accompanying transformation processes. Furthermore, it proposes an analysis method for water resources vulnerability based on connection entropy, which extends the concept of contact entropy. An e...
