More practical questions are whether introduced GEMs will survive in polluted matrices, or whether their continued viability will dramatically affect the success of remediation. A recent development in this area is the isolation of bacterial strains which can respond to selective agents under field conditions. These strains have been called field application vectors or FAVs, since their intended purpose is to express foreign genes in environments not conducive to the use of the parent organism (Lajoie et al., 1993). The proposed use of FAVs illustrates the need to control bacterial growth and survival under the real-world conditions where bacterial remediation has to occur.

In the application to the optical field, the vector potential (or the electric field in the lowest order) corresponding to carrier plane waves of given frequencies at,... 

The transformation of the volume integral over A into a surface integral over the volume s closed surface dA allows for the application of the surface flux boundary conditions of Eq. (3.35). The virtual electric potential gradient vSif may be represented by the virtual variant SE of the electric field strength vector of Eq. (3.39) ... 

Ferroelectricity is an electrical phenomenon and also an important property in solids. It arises in certain crystals in terms of spontaneous dipole moment below Curie temperature [1], The direction of this moment can be switched between the equivalent states by the application of an external electric field [2-4], It is observed in some crystal systems that undergo second-order structural changes below the Curie temperature, which results in the development of spontaneous polarization. This can be explained by Landau-Ginzburg free energy functional [3, 4, 9]. The ferroelectric behavior is commonly explained by the presence of domains with uniform polarization. This behavior is nonlinear in terms of hysteresis of polarization (P) and electric field (E) vectors. Phenomenological models of ferroelectrics have been developed for engineering computation and for various applications.

QuantlogP, developed by Quantum Pharmaceuticals, uses another quantum-chemical model to calculate the solvation energy. As in COSMO-RS, the authors do not explicitly consider water molecules but use a continuum solvation model. However, while the COSMO-RS model simpUfies solvation to interaction of molecular surfaces, the new vector-field model of polar Uquids accounts for short-range (H-bond formation) and long-range dipole-dipole interactions of target and solute molecules [40]. The application of QuantlogP to calculate log P for over 900 molecules resulted in an RMSE of 0.7 and a correlation coefficient r of 0.94 [41]. 

The present authors have had experience using rotary samplers for field studies involving relatively small droplets for vector control applications and for the measurement of droplet size at far-field distances. When using magnesium oxide slides, the spread factor for droplets varies from 0.75 for crater diameters up to 15 jam, to 0.8 for 15-20 p.m and 0.86 for crater diameters above 20 am.
