conclusions: the patients' waiting times and the number of patients waiting to receive services in both shifts could be reduced by using multitasking persons and reallocating them to the time-consuming stage of filling prescriptions, using queuing theory and simulation techniques. background: hospital pharmacy is responsible for controlling and monitoring the medication use process and ensures ...

deuterium substitution on two ortho-substituted-och2-fragments in nitro-benzo-9-crown-3 induces low frequency shifts, positive mndcj, in all 13c nmr resonances which is an indication of the increased shielding in this crown ether. the magnitude of these shifts vary from 15dc7=716 to 54dc3=15 ppb for c7 and c3 cd3cocd3, and c6d6 on mndcj values were investigated. the mndcj values depended more o...

A Dyck shift and a Motzkin shift are mathematical models for constraints on genetic sequences. In terms of the theory of symbolic dynamics, neither of the Dyck shift nor the Motzkin shift is sofic. In terms of the mathematical language theory, they are non-regular and context free languages. Therefore we can not use the Perron-Frobenius theory to calculate capacities of these constraints. O. Mi...

Hartree-Fock (HF) and Density Functional Theory (DFT) methods employed to study the effect of conformational change on the 13C chemical shifts of 6-mono axial and equatorial substituted and 6,7-di axial-axial, equatorial-equatorial and axial-equatorial substitutedderivatives of 5,6,7,8-tetrahydrodibenzo[a,c]cyclo-octene. The geometry of the conformers have been optimized...
