Relative density is an important index affecting the mechanical behaviors of calcareous sands.The dense sands present softening strength, whereas apac1/60/1/cw the loose sands exhibit hardening strength.Furthermore, the relative density is determined based on the maximum and minimum void ratios obtained by using the maximum and minimum dry density
A virologic surveillance program for A(H7N9) virus was conducted from April 15, 2013 to February 14, 2014 in Guangzhou, aiming to clarify the geographical distribution of A(H7N9) viruses among live poultry markets (LPMs) and poultry farms in Guangzhou.Virological and serological surveys of poultry workers were also apac1/60/1/cw conducted to evalua
Infrastructure resilience for a scenario can be assessed quantitatively from resilience curves that plot the evolution of system performance.Summary metrics map these curves to a single value to facilitate comparisons of different systems, scenarios, and policies.Commonly, these metrics are integral-based, e.g., cumulative infrastructure performanc
Human activities, primarily economic growth, and technological innovation, threaten global biodiversity.This study utilizes 22-year read more panel data from 87 developing countries and a novel cross-sectional heterogeneous factor analysis-based financial technology index to investigate how economic growth, renewable energy consumption, technologic
The first African dinosaur to be discovered, Paranthodon africanus was found in 1845 in the Lower Cretaceous of South Africa.Taxonomically assigned swisse high strength magnesium powder berry to numerous groups since discovery, in 1981 it was described as a stegosaur, a group of armoured ornithischian dinosaurs characterised by bizarre plates and s
