Absorber structure

Fig. 6. a, b - typical tomograms of dry cucumber seed of control and GMF groups c, e, g - cucumber seeds of GMF group after 5, 10 and 15 minutes in water accordingly d, f, h -cucumber seeds of the control group (the same time periods). Arrows indicate lens-shaped water absorbing structures. 

The data shown in Fig. 7.14 are somewhat different from those by Berman et al. [25] who reported a sulfur-removal efficiency of about 80% under the condition of C02 = 0 and at Ca/S = 1.0 (see Fig. 4 in Ref. [25] or Fig. 7.7 in this book). Possibly, this difference results from different absorber structures. In that used by Berman et al. spray droplets may collide rapidly on the wall, resulting in a significantly decreased effective interfacial area. 

X-ray scatter imaging can be performed in principle with such components as lenses and mirrors, though these suffer from poor efficiency beyond the soft X-ray region. In practice, X-rays having the penetrability (E0 > 40 keV) needed for explosives XDI can be collimated only by arrangements of pinholes, slits, etc. in otherwise absorbing structures. The collimation scheme to be used in a certain situation for XDI depends...

A related experiment, carried out with the cooperation of Karl G. Brandt on a stopped-flow apparatus, confirmed the results of the spectrophotometric experiment. It also provided an order of magnitude for the rate of the production and destruction of the 360 nm-absorbing structure under empirical conditions. In this experiment enzyme solution was rapidly mixed with substrate solution containing excess linoleic acid. As... 

Octyl triazone is a UVB absorber structurally unrelated to the benzophenones. Photocontact allergy to this agent in a sunscreen has been described (7). 

In foam injection-molded parts the anooth-skinned resilient foam produces a tough energy-absorbing structure that is being used as a wood substitute in athletic products such as lacrosse-stick heads and hockey-stick blades. Protective structures for helmets and automotive parts are under development. All are being produced in densities ranging for 0.35 to 0.7 g/cc (22 to 44 Ib/ft ). In those applications where added sti ess is desirable the use of glass or titanate fiber reinforcement with the foamed structure is very effective (6). 

These ultraviolet absorbers (Structure 2) have been homopolymer-ized with AIBN as the initiator and copolymerized with styrene, methyl methacrylate, and to a limited extent with n-butyl acrylate. The amount of incorporation of the functional monomer depended on the type of comonomer. A more extensive study of the copolymerization of methyl 5-vinylsalicylate was carried out with a substantial number of... 

It should be noted that to date, such radar absorbing structural materials (glass or Kevlar -F carbon) could not be processed by conventional weaving techniques. A brief calculation shows that the addition of a stealth function to conventional composites only results in a 50% mass uptake. For example, the architecture of... 

For that purpose, disaccharides (cellobiose, lactose, etc.) having a reducing end group, are introduced, in the presence of a reductant, on chitosan in the open-chain form (Yalpani and Hall 1984). These derivatives are water soluble. Fibers made of chitin and chitosan are useful as absorbable structures and wound-dressing materials (Nakajima et al. 1984, Muzzarelli 1997, Ravi Kumar 1999).
