Stress impacts telomere dynamics [PDF]

Biology Letters, 2007
Telomeres are DNA–protein complexes at the ends of chromosomes that control genomic integrity but appear to become shorter with age and stress. To test whether stress causes telomere attrition, we exposed the offspring of wild-caught house mice ( Mus musculus ) to stressful conditions and examined the changes in ...

Static, dynamic mechanical properties and microstructure characteristics of ultra-high performance cementitious composites

Science and Engineering of Composite Materials, 2012
A new type of construction material named ultra-high performance cementitious composite (UHPCC) was developed in order to reduce the production cost and energy consumption of reactive powder concrete (RPC). Six different mixture proportions of UHPCC were

Static and Dynamic Compressive Stress-Strain Behavior of Recycled Tire Crumb Rubber Mortar

Frontiers in Materials, 2020
Crumb rubber mortar (CRM) made from scrap tires can be used in highway, high-speed railways, and airport pavements as a structural material, which may help to solve the problems of raw material shortage and waste tire pollution at the same time.

Reconstruction of Reinforced Concrete Structures on The Example of Bridge Spans Damaged as a Result of Dynamic Impacts

Железобетонные конструкции, 2023
The problem of restoring reinforced concrete structures that have received dynamic impacts (emergency as a result of collisions with vehicles, damage as a result of dismantling nearby structures, explosive impacts) is quite an urgent issue.

Variability and methodological choices in articulatory suppression tasks: a review

Frontiers in Psychology
Researchers often examine the role of overt language and inner speech in cognition by using articulatory suppression as a form of verbal interference. The hypothesis behind is that it causally prevents participants from using verbal strategies during the

Research on the Tensile-Bending Dynamic Response of the Half-Through Arch Bridge Short Suspender Considering Vehicle-Bridge Coupling Vibration

Vibration
The half-through arch bridge short suspender is more prone to damage due to its high linear stiffness and special force characteristics. To analyze the vehicle-induced vibration characteristics of the short suspender during service, a half-through arch ...
