Is There a Role for Qualitative Risk Assessment? [PDF]

open access: yesarXiv, 2013
Classically, risk is characterized by a point value probability indicating the likelihood of occurrence of an adverse effect. However, there are domains where the attainability of objective numerical risk characterizations is increasingly being questioned.

Alarming Oxygen Depletion Caused by Hydrogen Combustion and Fuel Cells and their Resolution by Magnegas$^{TM}$ [PDF]

open access: yesarXiv, 2000
We recall that hydrogen combustion does resolve the environmental problems of fossil fuels due to excessive emission of carcinogenic substances and carbon dioxide. However, hydrogen combustion implies the permanent removal from our atmosphere of directly usable oxygen, a serious environmental problem called oxygen depletion, since the combustion turns ...

Homogenization Model for Aberrant Crypt Foci [PDF]

open access: yesarXiv, 2014
Several explanations can be found in the literature about the origin of colorectal cancer. There is however some agreement on the fact that the carcinogenic process is a result of several genetic mutations of normal cells. The colon epithelium is characterized by millions of invaginations, very small cavities, called crypts, where most of the cellular ...

Assessment of Pollutant Spread from a Building Basement with three Ventilation Systems [PDF]

open access: yesEuroAcademy on Ventilation and Indoor Climate - CLIMACADEMY Course 7: Experimental Assessment of Indoor Environment Parameters, Pamporovo : Bulgaria (2009), 2010
Ventilation aims at providing a sufficient air renewal for ensuring a good indoor air quality (IAQ), yet building energy policies are leading to adapting various ventilation strategies minimising energy losses through air renewal. A recent IAQ evaluation campaign in French dwellings shows important pollution of living spaces by VOCs such as ...

Dynamic DNA Processing: A Microcode Model of Cell Differentiation [PDF]

open access: yesarXiv, 2013
A general theoretical framework is put forth to organize and understand various observed phenomena and mathematical relationships in the field of molecular biology. By modeling each cell in eukaryotic organisms as a processor having a unique set of allowed states, represented by a specific DNA sequence, we demonstrate a method by which gene expression ...

Bayesian Model-Averaged Benchmark Dose Analysis Via Reparameterized Quantal-Response Models [PDF]

open access: yesarXiv, 2014
An important objective in biomedical risk assessment is estimation of minimum exposure levels that induce a pre-specified adverse response in a target population. The exposure/dose points in such settings are known as Benchmark Doses (BMDs). Recently, parametric Bayesian estimation for finding BMDs has become popular.

Bayesian Benchmark Dose Analysis [PDF]

open access: yesarXiv, 2014
An important objective in environmental risk assessment is estimation of minimum exposure levels, called Benchmark Doses (BMDs) that induce a pre-specified Benchmark Response (BMR) in a target population. Established inferential approaches for BMD analysis typically involve one-sided, frequentist confidence limits, leading in practice to what are ...
