An energetic view of stress: Focus on mitochondria

Maria del Carmen Sandi Perez

Energy is required to sustain life and enable stress adaptation. At the cellular level, energy is largely derived from mitochondria – unique multifunctional organelles with their own genome. Four main elements connect mitochondria to stress: 1) Energy is r ...

A cost-effective isogeometric approach for composite plates based on a stress recovery procedure

Pablo Antolin Sanchez, Alessandro Reali

This paper introduces a cost-effective strategy to simulate the behavior of laminated plates by means of isogeometric 3D solid elements. Exploiting the high continuity of spline functions and their properties, a proper out-of-plane stress state is recovere ...

Constitutive differences in habituation of the glucocorticoid response to stress are related to variation in aggression and anxiety-related behaviors

Maria del Carmen Sandi Perez, Olivia Zanoletti, Marie-Isabelle Guillot de Suduiraut, Sophie Elizabeth Walker

Glucocorticoids coordinate responses that enable an individual to cope with stressful challenges and, additionally, mediate adaptation following cessation of a stressor. There are important individual differences in the magnitude of glucocorticoid responsi ...

Influence of geometrical imperfections and flaws at welds of steel liners on fatigue behavior of pressure tunnels and shafts in anisotropic rock

Alexandre Jean Pachoud

The recent development of high-strength (HSS) weldable steels has enlarged the range of design alternatives for the optimization of high-head steel-lined pressure tunnels and shafts (SLPT&S) in the hydropower industry. With the liberalization of the Europe ...

Snow instability evaluation: calculating the skier-induced stress in a multi-layered snowpack

Johan Alexandre Philippe Gaume, Jürg Schweizer, Alec van Herwijnen

The process of dry-snow slab avalanche formation can be divided into two phases: failure initiation and crack propagation. Several approaches tried to quantify slab avalanche release probability in terms of failure initiation based on shear stress and stre ...

Fatigue design criteria for strengthening metallic beams with bonded CFRP plates

Alain Nussbaumer, Masoud Motavalli, Mario Fontana, Elyas Ghafoori

Different failure criteria used to prevent fatigue crack initiation in metallic members are described. A series of closed-form analytical solutions were developed to predict the fatigue resistance of metallic beams after strengthening with carbon fiber-rei ...
