Investigation on Seismic Response of Long-Span Special Steel Truss Cable-Stayed Bridge
Advances in Civil Engineering, 2022 Due to the small self-weight of the steel truss cable-stayed bridge with a single tower and a single cable plane, the torsional stiffness and wind stability of the structure are reduced. The arrangement of the deck type makes the mechanical properties of

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Interfacial behaviour in Tunnel engineering [PDF]
, 2021 The force imparted on the soil by a tunnel boring machine can lead to catastrophic tunnel collapse. To help predict this behaviour the machine is modelled as point source in an elastic/plastic idealized soil with no cohesion. The model predicts a wedge shaped region of plasticity extending from the machine.

Aerofoil behaviour at high angles of attack and at Reynolds numbers appropriate for small wind turbines [PDF]
, 2014 The aerodynamic characteristics of a NACA0018 aerofoil have been investigated experimentally for incidence angles ranging from 0° to 180° in closed-jet and open-jet wind tunnels with different blockage coefficients at Reynolds numbers from 60,000 to 140 ...

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

A Wind Tunnel Simulation Facility for On-Road Transients [PDF]
, 2014 This paper outlines the creation of a facility for simulating on-road transients in a model scale, ¾ open jet, wind tunnel. Aerodynamic transients experienced on-road can be important in relation to a number of attributes including vehicle handling ...
