Contract conclusion

Our primary interest in the Flory-Krigbaum theory is in the conclusion that the second virial coefficient and the excluded volume depend on solvent-solute interactions and not exclusively on the size of the polymer molecule itself. It is entirely reasonable that this should be the case in light of the discussion in Sec. 1.11 on the expansion or contraction of the coil depending on the solvent. The present discussion incorporates these ideas into a consideration of solution nonideality. [Pg.564]

Contracts usually contain clauses to govern the termination of projects upon completion at a specified renewal period or early termination for various reasons. Termination normally requires written notice with a specified time frame for conclusion and removal of... [Pg.65]

Non-isothermal measurements of the temperatures of dehydrations and decompositions of some 25 oxalates in oxygen or in nitrogen atmospheres have been reported by Dollimore and Griffiths [39]. Shkarin et al. [606] conclude, from the similarities they found in the kinetics of dehydration of Ni, Mn, Co, Fe, Mg, Ca and Th hydrated oxalates (first-order reactions and all values of E 100 kJ mole-1), that the mechanisms of reactions of the seven salts are probably identical. We believe, however, that this conclusion is premature when considered with reference to more recent observations for NiC204 2 H20 (see below [129]) where kinetic characteristics are shown to be sensitive to prevailing conditions. The dehydration of MnC204 2 H20 [607] has been found to obey the contracting volume... [Pg.134]

The obvious conclusion to be reached is that there are three kinds of spd orbitals hybrid bond orbitals, contracted d orbitals, and about 0.70 other orbitals. In 1938 I considered this 0.70 unstable orbital per atom to be unsuited for either bond formation or... [Pg.397]

One should note overall, that while some of these suggested mechanisms may in the future prove to have a role in the control of smooth muscle contraction, in chemically skinned preparations maximum force development follows activation by the MLCK active subunit in extremely low Ca " ion concentrations. The conclusion can hardly be avoided that phosphorylation alone is sufficient for activation, and if another mechanism is involved, it is not necessary for the initial genesis of force. If such mechanisms are operative, then they might be expected to run in parallel or consequent to myosin phosphorylation. A possible example of this category of effect is that a GTP-dependent process (G-protein) shifts the force vs. Ca ion concentration relationship to lower Ca ion concentrations. This kind of mechanism calls attention to the divergence of signals along the intracellular control pathways. [Pg.178]

Gelatin behavior in this system indicates that it behaves rod-like that tends to contract with increasing temperature. This conclusion is supported by the observed data from the hydrodynamic properties analyzed. [Pg.111]

Figs. 2 and 4 show that the cell contraction is almost the same for Mn2+ and Co2+ as covalency increases from fluorides to iodides or sulfides (thus the total 3d + 4s covalence is identical for both). However, the covalence of the 3d orbitals is 2 to 3 times smaller for Mn2+ (see Figs. 14a and 14b). Therefore Mn2+—X covalence results mostly from spin transfer to empty 4 s orbitals, unlike Co2+. This agrees with the conclusion of Rimmer (1964). [Pg.44]

In conclusion, gastric microflora is altered in patients with severe forms of intestinal pseudoobstruction due to frequent duodenogastric reflux episodes caused by abnormal retrogradely propagating contractions. [Pg.15]

If we now consider the numerical results quoted in Table 1 for the optimum exponents, three conclusions follow immediately. Firstly, the 1 s orbital on the heavy atom is unchanged by molecule formation this is to be expected. Second, the sp3 orbitals involved in the X—H bond are all contracted with respect to their free-atom values. Finally, the sp3 orbitals containing Tone pairs of electrons are largely unchanged or expanded slightly on molecule formation. In fact, of course, the optimum separate atoms minimal basis functions do not have the same orbital exponent for the 2 s and 2 p AOs. To facilitate comparisons therefore in Table 1 the optimum n = 2 exponent is given for the atoms when such a constraint is imposed (the qualitative conclusions are, in any event, unchanged by use of these exponents for comparison or a notional exponent of 1/4 (fs + 3 fp) or any reasonable choice). [Pg.70]

Dr. Harold Abramson, under a contract with the CIA in 1954, had reached a similar conclusion from a preliminary trial with four subjects. Based on his clinical judgment of response intensity, he estimated the inhalation dose to be only about one-third as effective as the same oral dose. In 1966, he gave me a hand-typed draft CIA report he had never published. The ingenuity of the technique he describes, using a rudimentary aerosol chamber, is evident in the report, which is provided on the following pages. [Pg.330]

Although an extensive discussion on the mechanism of the ring contraction of pteridines into purines is beyond the scope of this book, it can only be mentioned that conclusive proof has been obtained (77H205) that the ring contraction starts by addition of the amide ion to C-7 as well as to C-6, although the addition to C-7 is the main pathway (Scheme 11.44). [Pg.65]
