Abstract Babinskaiidae is an extinct family of the lacewing superfamily Myrmeleontoidea, currently only recorded from the Cretaceous.The phylogenetic position of this family is elusive, with inconsistent inferences in previous studies.Here we report on three new genera and species of Babinskaiidae from the mid-Cretaceous Kachin ECB Load Wire amber
Based on the mixed-lubrication theory, a numerical simulation model of a reciprocating seal is established.The model includes finite element, fluid mechanics, contact mechanics and deformation mechanics analyses.The hydrodynamic analysis uses elastohydrodynamic lubrication Western Reins theory and inverse hydrodynamic lubrication to obtain the rela
The new threats of modern warfare compel the thinking and development of a credible air defense capability based on early warning Door Opener Assembly systems, surface-to-air missiles, fighter aircraft and associated command and control systems.Ground-based air defence, largely neglected in the air campaigns that dominated the last years of militar
Importance When Pumps hospitals are at capacity, accurate deterioration indices could help identify low-risk patients as potential candidates for home care programs and alleviate hospital strain.To date, many existing deterioration indices are based entirely on structured data from the electronic health record (EHR) and ignore potentially useful in
The global lifestyle of this modern world has become more dependent on petroleum-based products, whose applications are involved almost everywhere.Since a large quantity of oil is being used on a daily basis, the spilling of oil by various means during its storage and transportation has become inevitable.This work focuses on the spilling of oil in
