Damage evolution and stability analysis of the Jianchuandong Dangerous Rock Mass in the Three Gorges Reservoir Area

, 2020
To analyze the deformation mechanism and to evaluate the stability of a dangerous rock mass, we investigated the Jianchuandong Dangerous Rock Mass (JDRM) in the Three Gorges Reservoir area.

On static stability of damaged columns

53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012
In this paper the effect of damage on the buckling loads and buckling modes of damaged Euler-columns is investigated. The analytical model used to investigate the effect is the “unified framework.” Unified framework has been used to obtain the expressions of mode shapes and natural frequencies of damaged-elastic structures in the field of structural ...

Role of senataxin in DNA damage and telomeric stability

DNA Repair, 2011
Ataxia with oculomotor apraxia type 2 (AOA2) is an autosomal recessive neurodegenerative disorder characterized by cerebellar ataxia and oculomotor apraxia. The gene mutated in AOA2, SETX, encodes senataxin (SETX), a putative DNA/RNA helicase. The presence of the helicase domain led us to investigate whether SETX might play a role in DNA damage repair ...

Stability Problems for Plates with Short-Term Damageability

International Applied Mechanics, 2001
The authors consider the problem on plates stability with account for microfractures in the material modelled by stochastically located empty pora. Two approaches are proposed for stability investigation of the plate with microfractures which are based on the well-known models of stability theory of elastoplastic bodies incorporating the concepts of ...

Damage Stability Making Sense

2019
Although aviation, nuclear, processing, etc. industries have long ago adopted and established preventative frameworks and procedures to safeguard against unwanted outcomes of daily operations, the maritime industry still places the emphasis on the mitigation of consequences following an accident.

Mobility and Repair of Damaged DNA: Random or Directed?

Trends in Cell Biology, 2019
The increased mobility of damaged DNA within the nucleus can promote genome stability and cell survival. New cell biology approaches have indicated that damaged DNA mobility exhibits random and directed movements during DNA repair. Here, we review recent

ATM signaling and genomic stability in response to DNA damage

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2005
DNA double strand breaks represent the most threatening lesion to the integrity of the genome in cells exposed to ionizing radiation and radiomimetic chemicals. Those breaks are recognized, signaled to cell cycle checkpoints and repaired by protein complexes. The product of the gene (ATM) mutated in the human genetic disorder ataxia-telangiectasia (A-T)

Stability, instability, and localization in materials with damage

Journal of Rheology, 1984
Generally, continuum theories of materials with damage treat the damage as an internal state variable, a variable whose evolution is governed by a rate‐type law. There is quite ample precedent, however, to treat such a quantity as governed instead by an equation of balance in addition to the conventional ones for mass, momentum, energy, and entropy ...

Thermal stability and radiation damage in the phthalocyanines

Australian Journal of Chemistry, 1974
The phthalocyanine (pc) complexes of a number of metals have been prepared. The e.p.r. spectra of the paramagnetic pc complexes (VO2+, Cr2+, Mn2+, Co2+, Cu2+, Mo2+) show metal ion resonances, while those of the diamagnetic pc complexes (H22+, Na22+, Mg2+, Ni2+, Zn2+, Pd2+, Cd2+, Sn2+, Pt2+ and Pb2+) generally give free spin resonances with g ≈ 2.003 ...
