General Methodology

The following methodology was applied to identify critical areas (according to the definition of critical areas within this project)  

Pollution level identification of zones and areas with levels above the limit values for PM10 and NO2 in 2007. Sources of information were the annual reports submitted according to Commission Decision 2004/461/EC [3], AirBase,1 time extension notifications,2 model calculations (e.g. EMEP3) and reports from ETC/ACC.4 Further, mostly qualitative information was derived from Europe-wide modelling and earth observation studies. 

Trends identification of zones and areas with stagnant or increasing PM, NOx and NO2 levels. Sources of information were annual reports (2004/461/EC), AirBase and time extension notifications. Separate analysis of the trends of NOx and NO2 levels helps to identify areas influenced by increasing primary N02 emissions from diesel vehicles. 

Investigation into the identification of possible indicators for critical areas , relating to the reasons for measured concentrations  

The indicators can be separated into those that cannot be influenced, such as climatic conditions and topography, and those which can be influenced partly (transboundary contributions, population density) or fully by the Member State (emissions, especially of relevant sources such as traffic, domestic heating, industry). These indicators have been visualised with the help of GIS and correlated with air quality indicators. 

SAFETY AND RISK ASSESSMENT FOR HYDROGEN CONTAINING SYSTEMS 8.7.1. General Methodology 

Technical systems which contain material representing a hazard potential must be treated under controled, safe conditions. A respective design of the facility and its operational modes is checked by different kinds of safety considerations. In addition to the consequences of normal operation, the system behavior under accident conditions has to be considered in terms of sufficient measures for controling accidents. Assumptions are being made based upon experience which has been achieved in the course of the technical development and which has resulted in a system of laws, regulations, rules, guidelines, and recommendations, e.g., for the design of components, for quality assurance, for fire protection and also for accident prevention measures. 

Not only is the selection of accident scenarios made on the basis of experiences, but also on the basis of intuition. It comprises both the reliability of the technical systems and the consequences of uncontroled accidents. Problems arise if conceivable accident scenarios start to leave the realm of direct experience and if the possible damage is getting high. 

It was typically in the nuclear technology that systematic prognosis procedures for the event and the consequences of uncontroled accidents were applied. They have been significantly improved over the last 25 years and are now an essential part of the valuation process of nuclear power plants in the form of probabilistic safety and risk assessments (PSA and PRA). 

The methodology of PSA is in principle a combination of event tree and fault tree analyses. The target of the analysis decisively determines the selection and the definition of modes in which the technical system is at the end of an event sequence. These modes comprise both the safe ones resulting from successful safety measures and also those unwanted ones characterized by a certain release of hazardous materials. A PSA is extended to a PRA, if the consequences of the different system modes are determined and linked with the event frequencies of those modes.

For a complete understanding of any electrochemical process, it is necessary to acquire information, not only concerning the mechanism of the primary charge transfer step in which a bulk species becomes discharged at the melt-electrode interface, but also about the form of that bulk species and its rate of transport up to the reaction plane. A knowledge of the final, equilibrium state of the product is also necessary, e.g., whether or not it becomes incorporated into the original electrode substrate. 

Electroanalytical techniques, essentially similar to those employed in aqueous solutions, can be adapted for use in melts to provide data on solution equilibria by way of stability constant determinations, ion transport through diffusion coefficient measurements, as well as mechanistic analysis and product identification from mathematical data treatment. Indeed, techniques such as linear sweep voltammetry and chronopotentiometry may often be applied rapidly to assess or confirm general characteristics or overall stoichiometry of electrode processes in melts, prior to more detailed kinetic or mechanistic investigations requiring more elaborate instrumentation and equipment, e.g., as demanded by impedance studies. Thus, answers to such preliminary questions as 

Advantageously, electroanalytical techniques may also be employed for in situ analysis and control of industrial processes, e.g., as currently practiced for anode effect control in aluminum electrowinning/  

Notwithstanding, the experimental simplicity of chronopotentiometry may still make it a first-choice electroanalytical technique for higher-temperature molten systems. Furthermore, in the current-reversal mode, it is one of only a few diagnostic techniques for assessing the classical reversibility of an electrode process. A recent review has surveyed many of its applications in this context, and so, bearing in mind the authors own interests, it seems appropriate to use examples of chronopotentiometric studies to illustrate some of the present aspects of current interest. 

Persistent reports indicate that the Stokes-Einstein equation may be valid in molten salts and that a suitable choice for the hydrodynamic friction constant a will be 4.67t, approximating to nearly complete slippage. The only explanation for this that has been offered so far is that the near-square potential energy wells in which ions reside in melts fortuitously resemble the Van der Waals interaction wells operating in the dielectric continuum envisaged in the original formulation in all respects except their strength. 

We begin the calculation of the cumulative reaction probability with an expression derived from the analysis of reactive flux correlation functions [4], given by 

In Eqs. (3.7) and (3.8), adding an infinitesimal imaginary part to the energy E provides the outgoing wave boundary conditions, and, in Eq. (3.8) can be viewed as providing a factor which ensures the convergence of the time integral [23]. 

Seideman and Miller recently showed [23], in the definition of that 

Here e is a coordinate dependent operator, and h is the coordinate dependent step function operator which defines the reactive flux in Eq. (3.4). If Eq. (3.9) is evaluated in a discrete variable representation [23, 53-56, 80] (DVR) in which case the absorbing potentials, and Cp, are diagonal, N E) becomes 

The computational challenge involved in Eq. (3.13) is clearly the evaluation of the matrix elements of G(E) which connect the reactant and product regions of

Additive invariants were first studied by Pomeau [pomeau84] and Goles and Vich-niac [golesSb]. Although, as we shall see below, there are some techniques that can be used to extract a few invariants from jjarticular systems, no general methodology currently exists. A fundamental obstacle appears to be that there is no purely discrete analogue of Noether s Theorem. 

A general methodology has been developed for the treatment of NMR data of polymer mixtures. The methodology is based on reaction probability models and computer optimization methods, resulting in a family of computer programs called MIXCO. The use of MIXCO programs enabled three components to be resolved from NMR tacticity data of fractionated polybutylene.
