Explosion load studies are an essential part of shield engineering design. This is especially true for explosion-proof plates, which used in order to reduce the impact explosions, have potential cause substantial damage structural elements. The purpose this study detail explosion phenomenon and response sandwich panel structures under explosive loading. finite element method (FEM) model dynamic...

It has long been known that armored scale insects harbor endosymbiotic bacteria inside specialized cells called bacteriocytes. Originally, these endosymbionts were thought to be fungal symbionts but they are now known to be bacterial and have been named Uzinura diaspidicola. Bacteriocyte and endosymbiont distribution patterns within host insects were visualized using in situ hybridization via 1...

Recent experiments and simulations have demonstrated that particle-covered fluid/fluid interfaces can exist in stable nonspherical shapes as a result of the steric jamming of the interfacially trapped particles. The jamming confers the interface with solidlike properties. We provide an experimental and theoretical characterization of the mechanical properties of these armored objects, with atte...

Particles floating at interfaces are commonly observed in nature, as well industrial processes. When the particles non-Brownian particles, large deformations of interface created that induce long-ranged capillary interactions and lead to formation particle rafts with unique characteristics. In this review we discuss recent efforts investigating raft role rafts’ own weight during dynamic cluster...

A new Hypoptopomatinae is described from the upper rio Jequitinhonha basin. The new species is distinguished from all congeners by having the ventral laminar expansions of cleithrum and coracoid bearing only 1-30 odontodes, restricted to the area near the pectoral-fin insertion; the anterior plates of mid-ventral lateral series reduced, not ventrally elongated, the first or the second markedly ...
