In large-scale high-speed rail networks (HSRNs), the occurrence of occasional malfunctions or accidents is unavoidable.The key issue considered in this study is the optimal allocation of the maintenance costs, based on the stochastic risk assessment for HSRNs.Inspired by the theoretical risk evaluation methods in the complex network, three major fa
Continued rise in incidence and prevalence of diabetes globally warrants an effective strategy for its prevention and control.Prevention of diabetes seems more logical to attempt seeing its health care burden, long dormancy, systemic affliction and poor general awareness.Pre-diabetes is the intermediate state of erratic glucose metabolism without o
Micro-engine was widely used in agricultural machinery and motorcycle equipment,especially in mower chain saws and other products by its advantages of Fridge Water Hose Tap Connector simple structure,reliable operation and high efficiency.In this paper,ones built the3 D model for micro engines which was actually used,in addition,the steady temperat
Selective catalytic reduction (SCR) is currently one of the most efficient denitration technologies to reduce nitrogen oxide (NOx) emissions of diesel engines.AdBlue (urea water solution, UWS) is the copyright of the reducing agent of SCR, and the spray process of UWS is one of the critical factors affecting denitration efficiency.In this paper, a
Abstract Core LC42, retrieved from the Central Basin of the northwestern Ross Sea, contains three distinct sediment facies (IRD (ice-rafted debris)-poor bioturbated sandy mud, IRD-rich massive sandy mud, and laminated mud) that are interleaved with each other and deposited over the last 1 Ma.The biogenic components (biogenic opal, total organic car
