Key properties and behavior

For M-E design, load—strain and interaction properties should be evaluated with a complexity similar to that of material models used for other pavement components in the design (Perkins et al., 2010). Several test methods have been developed specifically for this purpose, including  

Finally, the geotextile must have the required filtration/hydraulic characteristics to provide the coincident functions of separation, filtration, and drainage. Properties required for separation and filtration functions are related to opening characteristics

Nature of the critical cellular adduct. It is to be expected that the properties and behavior of the adduct formed with DNA will be of key importance. For example, the carcinogenicity of vinyl chloride has been attributed to its 7-N-(2-oxoethyl) derivative of guanine [60, 61]. 

The modern periodic table represents a pinnacle of the achievement of many nineteenth- and twentieth-century chemists, and is a clear visual expression of our understanding of the structure of the atom. It is not only beautiful, however - it is also supremely useful. It offers a simple key to predicting a wealth of physical and chemical data about the elements and their compounds. It is possible to predict the properties and behavior (biogeochemically, as well as chemically) of hundreds of compounds, from a knowledge of a few. It is the key to understanding modern chemistry. 

Major parf of analytical chemisfry is relafed to different spectroscopic techniques. In optical spectroscopy, ILs are already used as solvents for wide range of solutes to study their properties and behavior in conditions not available with organic solvents. ILs have their limits regarding the transparency, but knowing that many other limits are shifted far away. The use of ILs as solvents does not preclude the application of NMR techniques. After careful parameter adjustment, virtually all standard and advanced NMR techniques can be applied. The same can be said about mass spectrometry, which has a great potential to get a key method in almost all fields of IL research, including analytical applications with IL as necessary component to get good result. 

One of the key discoveries was the realization that very many real networks in nature, technology (e.g., the Internet and WWW) and human relations have similar structure and growth patterns, and can be described by the same mathematical formulas. All of them share similar properties and behavior. This discovery and the new theory have created an unprecedented opportunity for investigating resilience and vulnerabilities of the Internet and the WWW. For this reason we consider the scale-free network theory and related empirical results as being a significant development in the Cyberspace Security and Defense. 

Computational strategies will be key tools for the understanding of properties and behavior of materials to exploit the potential use of novel highly complex composite systems, new molecules and new multifunctional materials, also in membrane technology. 

Tye [38] explained that separator tortuosity is a key property determining the transient response of a separator (and batteries are used in a non steady-state mode) steady-state electrical measurements do not reflect the influence of tortuosity. He recommended that the distribution of tortuosity in separators be considered some pores may have less tortuous paths than others. He showed mathematically that separators with identical average tortuosities and porosities can be distinguished by their unsteady-state behavior if they have different distributions of tortuosity. 

The major differences between behavior profiles of organic chemicals in the environment are attributable to their physical-chemical properties. The key properties are recognized as solubility in water, vapor pressure, the three partition coefficients between air, water and octanol, dissociation constant in water (when relevant) and susceptibility to degradation or transformation reactions. Other essential molecular descriptors are molar mass and molar volume, with properties such as critical temperature and pressure and molecular area being occasionally useful for specific purposes. A useful source of information and estimation methods on these properties is the handbook by Boethling and Mackay (2000). 

The choice of solid carriers spans a wide spectrum (Table 1) from materials most suitable for research purposes (sintered glass beads, laterite stone deposited on a gramophone disk) to industrial materials (pumice, activated carbon, etc.). Key properties that affect the performance of the carrier are porosity (from impervious to controlled-size pores), composition (from ceramics to activated carbon), and hydrophilic behavior. It is difficult to perform a direct comparison of different carriers. Colonization and biofilm growth depend strongly on the nature of bacteria and on their intrinsic propensity to adhere on hydrophilic vs. hydrophobic surfaces.
