Applications of the Correlation Length
The correlation length is the system–dependent parameter, which defines the structure of the dominant current–carrying (electric or fluid) paths....

Pressure Saturation Curves and the Critical Volume Fraction for Percolation
The pressure-saturation curves of porous media give fundamental information about the pore space. In equilibrium, ignoring effects due to hysteresis,...
-
Effects of Multi-Scale Heterogeneity
It is generally agreed that problems with multi-scale heterogeneity present the biggest challenge to computation and understanding. A few such...
-
Environmental Oxidative Stress – Environmental Sources of ROS
Environmental factors are known sources for oxidative stress. In consequence of the numerous influences that define our environment, environmental...
-
Endogenous Oxidant-Generating Systems
Although organisms respiring air oxygen use their energy sources in an optimal way they are threatened by the compulsory formation of reactive oxygen...
-
Low Molecular Weight Antioxidants
Low molecular weight antioxidants are an important part of the antioxidative defense mechanisms of cells and organisms. This chapter gives a short...
-
Modulation of Cellular Signaling Processes by Reactive Oxygen Species
Exposure of cells to reactive oxygen species (ROS) may result not only in cell death by excessive oxidation of biomolecules but also cause the...
-
Glutathione
Glutathione is the most abundant non-protein thiol in cells. It is a tripeptide with two important structural features: the thiol group and the...

The Broad Spectrum of Responses to Oxidative Stress in Proliferating Cells
Proliferating mammalian cells exhibit a broad spectrum of responses to oxidative stress, depending on the stress level encountered. Very low levels...

Pesticides in the Great Lakes
Pesticides have been widely and heavily used in agriculture in the Great Lakes Basin (approximately 93000 tons were used in 1995 alone). Herbicides...
-
Brominated Flame Retardants in the Great Lakes
Brominated flame retardants in the Great Lakes have not been as well studied as many of the polychlorinated pollutants, especially PCBs, but in the...
-
Polychlorinated Biphenyls in the Great Lakes
This chapter reviews the scientific understanding of the concentrations, trends, and cycling of polychlorinated biphenyls (PCBs) in the Great...
-
Polycyclic Aromatic Hydrocarbons in the Great Lakes
Polycyclic aromatic hydrocarbons (PAHs) are produced during the incomplete combustion of organic material. They can also be produced through...
-
Persistent Organic Pollutants in the Great Lakes: An Overview
This chapter presents background information on the Great Lakes and summarizes the content of each chapter of this book.
-
Specific Examples of Critical Path Analysis
At the end of Chap. 1 the general technique of critical path analysis was introduced. This technique will actually form the basis of most of the...
-
Basic Constitutive Relations for Unsaturated Media
The following sections describe how to find the hydraulic conductivity, air permeability, electrical conductivity, as well as solute and gas...
-
Chemical Modifications of Biomolecules by Oxidants
There is strong evidence in support of the oxidation of biomolecules during normal physiology and under conditions of environmental or pathological...
-
Applications of the Cluster Statistics
This chapter presents a conceptually straightforward treatment of spatial correlations of “random” heterogeneous media, but does not intend to...

Porous Media Primer for Physicists
During the 1980's physicists (and some geophysicists) devoted considerable efforts to understanding the physical (meaning here not hydraulic)...
