In this study, we reported a portable kit consisting of a portable workstation, gold screen-printed electrode (SPE), 0.45 μm filter membrane, phosphate buffer solutions (PBS), and acetic acid (1%) for...

Experimental bird strike tests were conducted in which a 2.6-kg dead chicken was projected at a speed of 500 km/h to hit a raised aerodynamic brake wing. The brake wing was fabricated with a sandwich of composite material as its skin and polymethacrylimide foam as its core. Pre-test numerical analyses of bird strikes were performed using the LS-Dyna solver code, an Arbitrary Lagrangian Eulerian model of the bird, and a Lagrangian model of the brake wing. The numerical and experimental results were well correlated, confirming the validity of the finite element model and calculation approach. Finally, bird strikes were conducted on a brake wing extended to 75 and 90 to determine the difference between the two conditions on the basis of effective wind-drag area. Impact, failure after impact and high strength at impact properties were investigated for a composite of carbon and glass fibre laminate.

In this paper, a family of non-weight modules over Lie superalgebras S(q) of Block type are studied. Free U(η)-modules of rank 1 over Ramond-Block algebras and free U(h)-modules of rank 2 over Neveu-Schwarz-Block algebras are constructed and classified. Moreover, the sufficient and necessary conditions for such modules to be simple are presented, and their isomorphism classes are also determined. The results cover some existing results.
