Abstract The advancement of lightweight protective armors holds critical importance for enhancing the maneuverability and combat capabilities of helicopters.Leveraging insights from bionics, it provides a new idea for high-performance armor design.In this study, a new type of composite armor was designed by referring to the structural characteristi

In this study, indigenous acidophilic bacteria living in mine drainage and hot acidic spring were collected and used for bioleaching experiments.The incubated indigenous acidophilic bacteria were inoculated on various minerals.The changes in pH, Eh, and heavy metal concentrations were examined with uninoculated controls to study bioleaching over ti

During the shutdown of a gas turbine, natural convection flows occur inside of the engine casing.These natural convection flows cause the top of the engine casing to cool more slowly than the bottom of the casing.This non-uniform cooling can cause the DC Power casing to distort, known as “cat-back” distortion.This distortion leads to re

Waxing/waning of the ice sheets and the associated change in thermohaline circulation have played an important role in global climate change since major continental ice sheets appeared in the northern hemisphere about 2.75 million years ago.In the earliest glacial stages, however, establishment of the linkage between ice sheet development and ocean

The mining of oil sands in Alberta, Canada is a large-scale disturbance that requires land reclamation to equivalent land capability.Cover soils used for upland forest reclamation are forest floor mineral-mix (FFM) sourced from upland forest ecosystems and peat mineral-mix (PM) sourced from lowland ecosystems.Spatial heterogeneity and quantity of s
