An S S finding fulfills a prerequisite for a citation to be evaluated under one of MSHA s sternest enforcement mechanisms—the Unwarrantable Failure citation, which will be discussed in detail under the section on Orders of Withdrawal below. 

The value of the compresjiibility of oil is a function of the amount of dissolved gas, but is in the order of 10 x 10" psi" By comparison, typical water and gas compressibilities are 4x10" psi" and 500 x 10" psi" respectively. Above the bubble point in an oil reservoir the compressibility of the oil is a major determinant of how the pressure declines for a given change in volume (brought about by a withdrawal of reservoir fluid during production). 

The reaction of Ab-acetyl-1 -hydroxytryptamine (39) with mesyl chloride (MsCl) in THF in the presence of EtsN provides 1-acetyl-1,2,3,8-tetrahydropyrrolo[2,3-(j] indole (49a, 35%) (70JA343), Ab-acetyl-6-mesyloxytryptamine (50a, 4%), Ab-acetyl-2,3-dihydro-2-oxotryptamine (51a, 5%), l-acetyl-3a-(4-chlorobutoxy)-l,2,3,3a,8,8a-hexahydropyrrolo[2,3-(j]indole (52a, 7%), and Ab-acetyltryptamine (53a, 2%) as shown in Scheme 6 (2000H483). In the same reaction with MsCl, l-hydroxy-Ab-methoxycarbonyltryptamine (34) produces 50b (7%), 51b (34%), and 52b (9%), while the formation of 49b is not observed at all. In the case of Ab-trifluoroacetyl-l-hydroxytryptamine (48), 49c (45%), 50c (8%), 51c (4%), and 52c (6%) are produced. These data suggest that the yield of 49 increases, whereas the yield of 51 decreases in the order of electron-withdrawing ability of Ab substituents (COOMe < COMe < COCF3). Stability of 49 seems to govern the quantity of 51, which is probably formed by hydrolysis of 49. 

The reactivity of diphenyl (6, X=H) and dibenzoy] (7, X=H) disulfide derivatives is higher than aliphatic derivatives. The value of Ctr depends markedly on the substituents, X, and on the pattern of substitution. Electron withdrawing substituents (e.g. X = p-CU or /t-NCK) may increase Cir by an order of magnitude.59 60 However, these compounds also give marked retardation. 

Promoting an Optimal Response to Therapy When administering an anticonvulsant, the nurse must not omit or miss a dose (except by order of the primary health care provider). An abrupt interruption in ther-apy by omitting a dose may result in a recurrence of the seizures. In some instances, abrupt withdrawal of an anticonvulsant can result in status epilepticus. 

In the reaction with butanone, an equilibrium between the CH3-activated complex and the CH2-activated complex is observed and it is revealed that the former is a thermodynamic product and the latter is a kinetic product. These results indicate that the relative reactivity of the C-H bonds is in the order of 2>1>3, and the large and electron-withdrawing substituents retard the reaction. A plausible mechanism is shown in Scheme 63. When the oxy-... 

Mataka and coworkers further studied the exo/endo selectivity of outside attack products in the reactions of 96 and 97 with A-(5-X-phenyl)maleimides [56]. They found that the endo/exo selectivity is markedly dependent on the electronic nature of the substituent X (Scheme 47). The electro-withdrawing substituents such as NOj and Cl enhance enrfo-selectivity. The relative order of the enr/o-selectivity is NOj > Cl > H > OCH3. 

In an earlier series of experiments, Cullis and Ladbury examined the kinetics of the permanganate oxidation of hydrocarbons in acetic acid solution. Initial attack on toluene occurs at the methyl group and a total order of two was found. Electron-withdrawing agents reduced the rate of oxidation. However, the effects of added salts were complex and the authors believe that lower oxidation states of manganese are responsible for the oxidation. The oxidation of ethylbenzene produced acetophenone, the process being second-order with...
