Characterization of distamycin A binding to damaged DNA

Bioorganic & Medicinal Chemistry, 2008
We previously reported that distamycin A, a natural antibiotic known as a minor groove binder, could bind to DNA duplexes containing the (6-4) photoproduct formed at its target site, whereas the binding was not observed for duplexes containing the cis-syn cyclobutane pyrimidine dimer in the same sequence context. In this study, we have further analyzed

Damage mechanism characterization in composite damage tolerance investigations

Composite Structures, 1993
Abstract The investigation of damage tolerance of composite materials comprises a spectrum of topics. A review of research in the area of damage tolerance critically exposes the need to identify basic damage mechanisms in order to develop more damage-tolerant materials and structures.

Damage characterization by vibration test

Scripta Metallurgica et Materialia, 1994
For load-bearing structural materials, damage is a generic term for the deterioration process that weakens the strength and integrity of materials. It may refer to macrocracks or to the deterioration process that precedes the formation of a dominant macrocrack, such as void nucleation and growth during creep, and plastic deformation or microcrack ...

Dynamic Characterization and Damage Identification

2011
This chapter presents selected cases of modal parameter evaluation and damage identification, privileging the applied aspects. The identification of modal parameters is discussed through three experimental cases of masonry structures: a civil building, a monumental structure and a nineteenth century railway bridge.

Microstructural characterization of fretting damage

Wear, 1993
Abstract A fretting rig has been built which can be operated in a well-controlled, oil-free atmosphere. Nickel has been used as a model material, and surface analytical and microscopic techniques, including transmission electron microscopy, were used to characterize the damage.

Thermography for Characterization of Corrosion Damage

CORROSION 2000, 2000
Abstract Thermography is a viable NDE technique for the characterization of corrosion in metallic materials. Thermography is a rapid, non-contact, wide area inspection technique that is easy to interpret and that in not significantly sensitive to material curvature.

Characterization of Topside Mechanical Damage

Volume 2: Pipeline Integrity Management, 2014
Mechanical damage, such as gouge, is the damage to the pipe surface caused by external forces and is usually caused by third-party damage during construction and excavation. This normally results in a highly deformed, work hardened surface layer with possible metal removal. In many cases, dents are coincident with gouges.

Micromechanics characterization of sublaminate damage

International Journal of Fracture, 1990
A micromechanics analytical model is developed for characterizing the fracture behaviour of a fibre reinforced composite laminate containing a transverse matrix crack and longitudinal debonding along 0/90 interface. Both the matrix and the fibres are considered as linear elastic.

Characterization of Damaged Skin by Impedance Spectroscopy: Chemical Damage by Dimethyl Sulfoxide

Pharmaceutical Research, 2013
To relate changes in the electrochemical impedance spectra to the progression and mechanism of skin damage arising from exposure to dimethyl sulfoxide (DMSO).Electrochemical impedance spectra measured before and after human cadaver skin was treated with neat DMSO or phosphate buffered saline (control) for 1 h or less were compared with electrical ...
