Characteristics primary

The solution of the gas flow and temperature fields in the nearnozzle region (as described in the previous subsection), along with process parameters, thermophysical properties, and atomizer geometry parameters, were used as inputs for this liquid metal breakup model to calculate the liquid film and sheet characteristics, primary and secondary breakup, as well as droplet dynamics and cooling. The trajectories and temperatures of droplets were calculated until the onset of secondary breakup, the onset of solidification, or the attainment of the computational domain boundary. This procedure was repeated for all droplet size classes. Finally, the droplets were numerically sieved and the droplet size distribution was determined. 

Depending on type, uranium deposits exhibit characteristic primary alteration and trace element zoning patterns, the latter commonly including, but are not limited to, elements exhibiting changes in oxidation state such as vanadium, selenium, molybdenum, arsenic, cobalt, and nickel (Fig. 3). It can be shown that... 

The method is based on the principle of chromatographic separation of components of a mixture on a GC column, followed by their identification from their mass spectra. The compounds are separated on a suitable GC column, following which, the components eluted from the column are subjected to electron-impact or chemical ionization. The fragmented and molecular ions are identified from their characteristic mass spectra. Thus, the substances present in the sample are determined from their characteristic primary and secondary ions and also from their retention times. 

As discussed previously, the radicals produced upon irradiation of water [Eq. (I)] have very different characteristics. Primary radicals (OH, H and e q) and their interactions with amino acids will be addressed first. The two secondary radicals that will be discussed... 

Although E. coli class I and L. leichmanii class II RNR possess characteristic primary and quaternary structures and distinct metallocofactors, they proceed by a similar mechanism, involving an essential thiyl radical [22]. The function of this radical is to abstract the hydrogen atom at the 3 position of the ribose in order to facilitate the cleavage of the (2 )C-OH bond and the reduction of the ribose by a redox active cysteine pair (Scheme 10-2). After each catalytic cycle this pair now as cystine must be reduced for the next cycle. In class I and II RNRs, this occurs by transthiolation from small proteins (such as thioredoxin) that themselves contain redox-active cysteine pairs. 

The vast majority of enzymes are proteins having a polypeptide chain with a complex three-dimensional structure. Enzyme activity is closely related to conformational structure with characteristic primary structures [i.e., specific amino acid sequences] which form an active site. At the active site, the interaction between the enzyme and substrate takes place leading to a chemical reaction, giving a particular product.

The oxidation behavior of the coating is depicted in Fig. 25.7. Internal oxidation increased with time. In comparison to the 25Cr-35Ni-Fe, the coating displayed minimal scale formation for the exposure times investigated. The predominant surface oxide species were identified by XRD and AES techniques. An interfacial barrier was noted to form and its formation appeared to be time-dependent. An examination of the substrate near the coating interface (Fig. 25.7) compared with that of the as-received structure. Fig. 25.8, revealed the characteristic primary carbide network had been unaffected by the oxidizing enviromnent.
