ABSTRACT Marchantia emarginata Reinw., Blume & Nees, with nearly 30 assigned names, is considered the most taxonomically complex species in the family Marchantiaceae.Currently, this species is segregated into three subspecies, and this subspecific classification is widely accepted since its formal inception.However, due to its extensive morphologic
The pile-beam composite structure in high-elevation debris flow areas is selected as the research object.Based on characterizing the pile-beam composite structure, the particle-flow simulation analysis program and the explicit dynamic analysis program were used to Classic Cap study comparatively the blocking effects of single-row piles and two-row
Reducing energy consumption is a demanding issue considering the limited available energy resources and increasing environmental pollution.On the other hand, industry consumes a huge amount of energy, and manufacturing processes are the most energy consuming portions of the industry.Machining issues including cutting tool geometry and process param
