Nuclear rationale

The rationale for the development of such fibers is demonstrated by their appHcation in the medical field, notably hemoperfusion, where cartridges loaded with activated charcoal-filled hoUow fiber contact blood. Low molecular weight body wastes diffuse through the fiber walls and are absorbed in the fiber core. In such processes, the blood does not contact the active sorbent direcdy, but faces the nontoxic, blood compatible membrane (see Controlled RELEASE TECHNOLOGY, pharmaceutical). Other uses include waste industrial appHcations as general as chromates and phosphates and as specific as radioactive/nuclear materials.

AMI semi-empirical calculations of structures 23-25 have been carried out to provide a rationale for the obtained nuclear magnetic resonance (NMR) results (Section 12.10.3.3.1). According to the calculations, compound 25 is planar with E conformation having the =C(CN)2 group directed toward the H-2 <1997MI113>. 

The rationale for understanding nuclear Tfi in weakly ma netically coupled dimers is that metal ions with large rs which interact with metal... 

Using the basic rationale of EMA theory [267], the parametric function e(q) becomes p q) = E—Hn when the kinetic energy of nuclear motion cannot be neglected. However, the operator (erflS(q) — op(q)) has a well-defined c-number value in vibrational eigenstates determined by the eigenvalue equation... 

A third and provisionally accepted explanation is that electron transfer can take place to vibrationally excited states of the products, i.e. nuclear tunnelling of the reactants to vibrationally excited states of the products takes place (Efrima and Bixon, 1974, 1976). The potential surfaces depicted in Fig. 10 show the rationale behind this mechanism. For AG° > — X (Fig. 10a) we have the normal situation with an activation barrier for electron transfer. At AG0 = —X (Fig. 106) the maximum rate for an activationless process has been reached, whereas for AG° < —X an activation barrier appears again (Fig. 10c, representing the inverted region). With electron transfer allowed to an excited vibrational level (dotted line in Fig. 10d) we have once again an activationless reaction proceeding at the maximum rate. For large molecules there is a... 

The rationale for this distribution of signal intensities can be understood from Fig. 11.59, which shows how five nuclear spins interact ... 

A particularly intriguing example occurs in the complex of the interaction domain of ACTR and the nuclear coactivator binding domain (NCBD) of CBP. CD spectra show that although neither of the free proteins is cooperatively folded, the complex is folded and stable. The 3D structure of the complex [23] demonstrates one of the rationales for the existence of intrinsically unstructured proteins the surface area of contact between the two proteins (Fig. 6.5) is much larger than could be expected from the interaction of folded proteins of comparable size, as has been pointed out [29]. 

The first term is electron-nucleus attraction, while the second is nuclear-nuclear repulsion. The potential energy is lowest when the electron is near one of the nuclei or close to both of them. We conclude that bond formation permits the electron to be located in a large region of space for which the energy is low. The total energy is lowered by forming the bond. We have found the rationale for bonding Occupation of an orbital such as... 

Properties of Plutonium. As nuclear power utilization with its associated reprocessing and waste disposal operations expands, the fate of any released plutonium assumes greater importance. However, there is another rationale for studying the environmental behavior of plutonium. Because of its solution chemistry, it is an element with rather unique qualities as a probe of environmental properties.
