Confined limitations, remaining

Releases of hazardous materials postulated to occur as a result of DBAs that would exceed DOE release guideline should be limited by designing facilities such that at least one confinement system remains fully functional following any credible DBA (i.e., unfi Itered/unmitigated releases of hazardous levels of such mater i a Is shouId not be a 11 owed following such acc i dents). 

To date, the phonon confinement effects have not been explicitly detected for CVD diamond films and results remained unsatisfactory in the case of DND. To improve the agreement between the predictions of the model and experimental Raman spectra of DND, effects such as crystal size distribution, lattice defects, and the energy dispersion of the phonon modes were taken into consideration and incorporated into the PCM. This work has shown that phonon wave vectors from small vibration domains lead to a broad shoulder peak at 1250 cm", that is often observed in the Raman spectrum of DND. Although the agreement between experimentally obtained and calculated Raman spectra has been significantly improved, some limitations remain, as was pointed ont in Ref. 98. The limitations imposed by the small ND size on the applicability of the PCM arise from the assumption that nanocrystals of 3-20 nm in size, showing extensive surface reconstruction and lattice defects, are assumed to have the phonon density of states of bulk diamond. 

Bone and tooth enamel from modem animals were collected in 1984 and 1993 from skeletons exposed on the surface in Sibiloi National Park, located on the east shore of Lake Turkana in northern Kenya. In addition to its interest as the site of numerous fossil hominid discoveries, the Turkana area provides an ideal controlled situation for the present study. The park is a circumscribed area surrounded by human pastoral groups and the nondomestic fauna remain to a great extent within its confines. Water sources are limited to the lake, ephemeral streams, a limited number of waterholes, and the plants eaten by the animals. The streams last on the order of days and in dry years do not flow at all. The non-domestic animals from which the bone and enamel were collected likely obtained most of their drinking water from the lake itself Domestic animals entered the park in 1984 during a severe drought. Their drinking water sources may have varied widely. 

Roman and later period may have been very limited, and confined to places in the Near East where there is a good supply of natron and suitable sand (Freestone et al., 2008). In the absence of any archaeological evidence, however, the actual locations of any major sites of Roman glass making remain unknown - a fact which, given the ubiquity of glass in the Roman empire, is little short of astonishing. 

If, however, solid electrolytes remain stable when in direct contact with the reacting solid to be probed, direct in-situ determinations of /r,( ,0 are possible by spatially resolved emf measurements with miniaturized galvanic cells. Obviously, the response time of the sensor must be shorter than the characteristic time of the process to be investigated. Since the probing is confined to the contact area between sensor and sample surface, we cannot determine the component activities in the interior of a sample. This is in contrast to liquid systems where capillaries filled with a liquid electrolyte can be inserted. In order to equilibrate, the contacting sensor always perturbs the system to be measured. The perturbation capacity of a sensor and its individual response time are related to each other. However, the main limitation for the application of high-temperature solid emf sensors is their lack of chemical stability. 

Boundary Diometer Precise detn of the velocities of deton in cylinders of cast TNT(Buxton rotating -mirror camera) shows that the vel rises as the diam is increased from a "boundary diam , below which there is no propagation, to a "limiting diam at which the deton vel reaches a max. The effect of heavy confinement is to reduce the boundary and limiting diams the max vel remains unaltered Ref W.B.Cybulski et al,PrRoySoc 197A, 51-72 (1949) CA 44,1707-8(1950)...
