Parasite stress predicts offspring sex ratio. [PDF]
PLoS ONE, 2012 In this study, I predict that the global variation of offspring sex ratio might be influenced in part by the level of parasite stress. From an energetic standpoint, higher gestational costs of producing a male offspring could decrease male births in a ...

Stress Dilatancy of Sand at Small Stress Ratio States
Soils and Foundations, 1990 The validity of the stress dilatancy equation for representing the small stress ratio state response of sand is examined. Test equipment development and procedures that were followed aimed at precise loading control and reliable monitoring of small displacements and volume changes.

The male to female ratio at birth [PDF]
, 2014 The factors that influence the male to female ratio at birth are legion. Males are usually born in excess and stress decreases the ratio while wellbeing and good health tends to increase it.

Predicting fatigue crack growth rate in a welded butt joint: The role of effective R ratio in accounting for residual stress effect [PDF]
, 2009 A simple and efficient method is presented in this paper for predicting fatigue crack growth rate in welded butt joints. Three well-known empirical crack growth laws are employed using the material constants that were obtained from the base material ...

Effect of High-Temperature Pavement Paving on Fatigue Durability of Bearing-Supported Steel Decks
Applied Sciences, 2020 Orthotropic steel deck (OSD) is a better choice for urban bridges and the replacement of damaged concrete slabs. Gussasphalt concrete (GAC) is usually adopted as the asphalt surfacing; however, the paving temperature of GAC is high, which will affect the
