Field-dressed surface

After the volunteer is dressed and outfitted with appropriate gear for the study, he/she may have to walk only a short distance to the field site or may need to be transported to the field site via a vehicle. When transporting the volunteer(s) by a vehicle, the seats of the vehicle should be covered with plastic sheeting. The volunteers should be escorted into the vehicle and asked to keep their hands off surfaces in the vehicle. The volunteers are then transported to the field site. The plastic seat covers need not be changed until after the volunteers have been transported back to the dressing area for post-exposure processing. The plastic seat covers should be changed before a new set of volunteers enters the vehicle. 

A seed dressing method based on electrons was developed and tested by Lindner et al. (1996) and Schauder (2003) as a direct method to improve seed quality and remove/reduce seedborne disease inocula. Electron seed dressing effectively removed common bunt spores (Tilletia caries) and reduced bunt levels compared to untreated seeds in field trials. However, its efficacy against M. nivale has not, as yet, been confirmed. Since this technique has potentially negative effects on germination rates of seed, it is limited to surface treatments (Jahn, 2002 Jahn et al., 2005). 

S. A. Rice The coupled matter-radiation system considered in the control schemes can, indeed, be studied from the point of view of dressed potential-energy surfaces, as suggested by the remark by Prof. Quack. We find it more convenient to use the equivalent point of view of continuous transfer of amplitude back and forth between the undressed potential-energy surfaces, because the formalism we have developed calculates the temporally and spectrally shaped field for that dynamical representation. 

Fig. 1.1. Schematic view of the Coulomb explosion imaging of nuclear dynamics. Molecules exposed to an intense laser field undergo structural deformation in response to the formation of light-dressed potential energy surfaces, and decompose into fragment ions after multiple ionization. Since the momentum vectors of fragment ions sensitively reflect the geometrical structure just before the Coulomb explosion, the ultrafast nuclear dynamics of a molecule in an intense laser field can be elucidated through measurements of the momenta of fragment ions...

Figure 8. Surfaces of eigen-energies (in units of 8) as functions of Qp/8 and 0 /8 when the dressed states (denoted A-i, X-2, and A-3, respectively connected to E, Ei, and 3 for fields off) are such that X2 < < X3, with...

To that effect, we choose the parameters 8 = 2flo and Qmax = 4.4 f>o, corresponding to the path (c) on the surfaces in Fig. 19. As shown in Fig. 22, the solution of the semiclassical Schrodinger equation (321) leads to nearly complete population transfer from state 11) to state 3). The analysis of the surfaces shows that the state 1 0,0) connects 3 —3,3). Thus the complete population transfer from the bare state 1) to the bare state 3) must be accompanied with absorption of three pump photons and emission of three Stokes photons at the end of the process. This is confirmed by the numerical solution of the dressed Schrodinger equation (308) with the initial state as a number state for the photon field 11 0,0), shown in Fig. 23a the dressed state vector /(f) approximately projects on the transfer eigenvectors during the process. It shows... 

A direct consequence of the observation that Eqs. (12.55) provide also golden-rule expressions for transition rates between molecular electronic states in the shifted parallel harmonic potential surfaces model, is that the same theory can be applied to the calculation of optical absorption spectra. The electronic absorption lineshape expresses the photon-frequency dependent transition rate from the molecular ground state dressed by a photon, g) = g, hco ), to an electronically excited state without a photon, x). This absorption is broadened by electronic-vibrational coupling, and the resulting spectrum is sometimes referred to as the Franck-Condon envelope of the absorption lineshape. To see how this spectrum is obtained from the present formalism we start from the Hamiltonian (12.7) in which states L and R are replaced by g) and x) and Vlr becomes Pgx—the coupling between molecule and radiation field. The modes a represent intramolecular as well as intermolecular vibrational motions that couple to the electronic transition...

The modification of polymers and fibrous surfaces to alter the porosity, wettability and other characteristics of polymeric substrates, will enable the prodnction of implants and biomedical devices which exhibit greater resistance to microbial adhesion and biofilm formation. A nnmber of polymers have been developed that can be incorporated into cellulose and other materials, which will provide significant advances in many fields snch as food packaging, textiles, wound dressings, coating of catheter tnbes and sterile surfaces. 

Sucrose esters are non-ionic surface-active materials which could be utilized as emulsifiers and fat replacers.They are synthesized by esterification linking lipophilic fatty acids to the hydrophilic sucrose. Especially the three primary OH groups of sucrose are more easily substituted through fatty acids compared to the secondary ones, thus leading preferably to mono-, di- and tri-esters. These lower-substituted sucrose esters are well suited for application as food emulsifiers especially in dressings and sauces, confectionery, icings and bakery fillings. Cosmetics are another important field of application. 

Silicone elastomers have a long history of use in the medical field. They have been applied to cannulas, catheters, drainage tubes, balloon catheters, finger and toe joints, pacemaker lead wire insulation, components of artificial heart valves, breast implants, intraocular lenses, contraceptive devices, burn dressings and a variety of associated medical devices. A silicone reference material has been made available by the National Institutes of Health to equate the blood compatibility of different surfaces for vascular applications. This material is available as a silica-free sheet. Contact the Artificial Heart Program, NHBLI, NIH, Bethesda, Md. for further information.
