Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Creep characteristics of frozen soils

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979
Abstract Consideration of the creep characteristics of frozen soil is required when it is used for the construction of retaining walls. It is generally accepted that there are three kinds of frozen soils, i.e., frozen soil without ice lenses, frozen soil with layers of ice lenses and frozen soil with needle-like ice lenses, influenced by freezing ...

Compression Creep Characteristics and Creep Model Establishment of Gangue

Geotechnical and Geological Engineering, 2016
How to describe the compression creep behavior of gangue is very essential for the design of gangue backfilling mining. In this paper, compression tests of two kinds of gangue are studied, finding that logarithmic function is suitable for describing its equal-time stress–strain relationship. Stress–strain–time relationship is proposed through modifying

Characteristics of creep deformation in ceramics

Materials Science and Technology, 1991
AbstractThe creep mechanisms in ceramics are reviewed briefly and then compared with experimental data. It is shown that there are three major types of creep behaviour: a stress exponent close to 5 due to control by dislocation climb and fully ductile behaviour; a stress exponent close to 3 due to control by climb from Bardeen–Herring sources and less ...
