Aestivation and diapause syndromes reduce the water balance requirements for pupae of the Hessian fly, Mayetiola destructor

Abstract

We report the water balance of aestivating (summer), diapausing (winter), and non-diapausing pupae of Hessian fly, Mayetiola destructor (Say) (Diptera: Cecidomyiidae).

Organic–inorganic hybrid melting gels

Melting gels are a class of organically modified silica gels that are rigid at room temperature, flow at temperature T1 and consolidate at temperature T2 (T2 > T1), when crosslinking is complete.

Micromechanism of cleavage fracture at the lower shelf transition temperatures of a C–Mn steel

This paper investigates the mechanism of cleavage fracture in precracked specimen made of Q-T C?Mn steel at the lower shelf of ductile-to-brittle transition curves. The results reveal that the lower shelf region can be divided into three domains: (1) at the lower temperature end (?150 to ?130?

McKibben artificial muscle using shape-memory polymer

When McKibben artificial muscle actuators are used to drive robotic joints, they are typically configured in pairs which act antagonistically to increase joint stiffness. However, this configuration cannot maintain a fixed position without continuous control.

Temperature- and pH-responsive behaviour of poly(2-(2-methoxyethoxy)ethyl methacrylate-co-N,N-dimethylaminoethyl methacrylate) hydrogels

Hydrogels with pH/temperature responsiveness and high water uptake have been synthesized by the free radical polymerization of 2-(2-methoxyethoxy)ethyl methacrylate (MEO2MA) with N,N-dimethylaminoethyl methacrylate (DMAEMA) in a low proportion.
