However, also in countries characterized by a large diffusion of industrial clusters, such as Italy, there are no operating EIPs.
Moreover, in the last few years, the utilization of hematopoietic growth factors and peripheral stem cells has permitted a large diffusion of this approach.
The recent years have witnessed a large diffusion of wireless sensor networks in different application scenarios: agricultural fields monitoring, environmental pollution monitoring, search and rescue operations in contaminated areas, antimining operations, and so forth.
It is also important to underline that Rome has to be seen as a very special and interesting urban area in which there is the overlapping of different phenomena: a quite compact central area compared to the surrounding zones characterized by very low densities, a level of automobile ownerships similar to American cities and a large diffusion of motorcycles as in many developing countries's cities.
Therefore, knowing the potential of the solar resource accurately is not only a need, it is also an imperative for a larger diffusion and use of the solar energy.
This is probably due to a larger diffusion and absorption of the compound by the filter paper.
The high performance of fuel cells requires a large diffusion coefficient, i.e. the diffusivity, of the gas transport in electrodes and efficient gas diffusion can lead to large limiting currents and controlled concentration polarization.
In a small number of cases, however, the actual observation of large diffusion of information might be possible.
The large diffusion of concurrent and distributed systems has spawned in recent years a variety of new formalisms, equipped with features for supporting an easy specification of such systems.
That has been advanced due to the large diffusion of the personal computer and the numerical algorithms.
