Chemical models and radiation damage

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1985
Abstract E.s.r. spectroscopy has been used in conjunction with an aqueous flow system to investigate both the metal-catalysed decomposition of hydrogen peroxide to OH* and the subsequent reactions of this radical with a variety of biomolecules. Particular emphasis is placed on the effects of pH and ligand on the FeII—H2O2 reaction and

On Nonstationary Cumulative Damage Models

Journal of Applied Mechanics, 1982
In this paper, we continue our study of embedded Markoff Chain Models of Cumulative Damage. We introduce and discuss a time transformation that leads to a condensation method. This method appears to be unusally comprehensive and a practical way to study nonstationary models of cummulative damage.

A Probability Model of Radiation Damage

Nature, 1952
IN developing the mathematical theory of radiobiological phenomena it is necessary to consider two separate, yet related, problems. The first problem is concerned with the probability of occurrence of effective ionizing radiations within a so-called sensitive volume (or mass) of a living organism.

Damage Losses Assessment Models

2016
The chapter focuses on the definition of a loss function which has been one of the first indicators used to determine resilience. Different models to evaluate the damage losses are provided, approaching the problem in probabilistic terms using fragility functions and analyzing the different type of uncertainties which appear in the resilience ...

A damage model for the assessment of storm damage to buildings

Engineering Structures, 2008
This paper presents a new model for the calculation of number and monetary amount of damage to residential buildings exposed to winter storm winds. The damage model is derived based on physical evidence and logical assumptions and is embedded in a mathematical framework.

Multiple sclerosis – a response-to-damage model

Trends in Molecular Medicine, 2009
According to a widely supported but unproven concept, the autoimmune mechanisms that drive neuroinflammation in multiple sclerosis (MS) are triggered by virus infection. However, a direct viral trigger of MS has not been identified. MS models in non-human primates suggest that lifelong asymptomatic infection with certain herpesviruses (e.g ...

Modelization of damage by abrasion

Wear, 1993
Abstract This paper takes steps to determine the non-negligible parameters governing the wear process. Modelization leads to the generalization of the Archard law. A new non-dimensional law is proposed in which the sharpness of the abrasive, its mineralogical hardness and the microstructural characteristics (elasto-plasticity and toughness) of the ...

Light Damage as a Model of Retinal Degeneration

2012
The induction of retinal degeneration by light exposure is widely used to study mechanisms of cell death. The advantage of such light-induced lesions over genetically determined degenerations is that light exposures can be manipulated according to the needs of the experimenter. Bright white light exposure can induce a synchronized burst of apoptosis in
