Poor sleep the night before an Experimental Stress task is associated with reduced cortisol reactivity in healthy women.
Biological Psychology, 2006Co-Authors: Caroline E. Wright, Joel Erblich, Heiddis B Valdimarsdottir, Dana H. BovbjergAbstract:Sleep disruption is a growing problem that may have serious health effects. As Stress-induced increases in cortisol are thought to be a key adaptive process it is important to examine how this response is affected by sleep. The current study investigated the association of four sleep parameters (objective/subjectively measured sleep quality and quantity) and subsequent salivary cortisol reactivity (maximal change from baseline) to an Experimental Stressor in 53 healthy women. Objective actigraphy monitoring and self-report diaries were used to assess sleep. Results revealed that individuals with lower objective sleep quality (wake percentage during sleep) had a blunted response to the Experimental Stressor. No associations were found between cortisol reactivity and actigraphy-derived sleep quantity, or either of the self-reported sleep variables. Results are discussed with regard to the possible adverse health effects that may result from poor sleep quality and a blunted cortisol response to Stress.

Molecular modelling of the Stress-strain behaviour of elastomers in pure shear
Polymer, 2005Co-Authors: J. I. Cail, Robert F. T. SteptoAbstract:Abstract It is demonstrated that Experimental Stress–strain data for several types of polymer network under pure shear display an approximately universal behaviour. The Monte–Carlo network-modelling method of Stepto, Taylor and Cail is extended to treat Stress–strain behaviour in pure shear and its predictions are in good agreement with the Experimental data. The predictions of Gaussian network theory are shown to be seriously in error.

a dislocation density based 3d crystal plasticity model for pure aluminum
Acta Materialia, 2009Co-Authors: Alankar Alankar, I N Mastorakos, David P FieldAbstract:Abstract A dislocation-density-based crystal plasticity finite-element model (CPFEM) is developed in which different dislocation densities evolve. Based upon the kinematics of crystal deformation and dislocation interaction laws, dislocation generation and annihilation are modeled. The CPFEM model is calibrated for pure aluminum using Experimental Stress–strain curves of pure aluminum single crystal from the literature. Crystallographic texture predictions in plane-strain compression of aluminum are validated against Experimental observations in the literature. The framework is implemented in ABAQUS with user interface UMAT subroutine.
