Metal vial closures and hepatitis.

Risk of latex allergy from pharmaceutical vial closures.

tively brief preoperative abstinence from smoking (less than 8 weeks) does not increase pulmonary risk compared with continued smoking. Indeed, we are not aware of any individual study that has found a statistically significant increase in pulmonary complications with brief preoperative abstinence, including the two initial studies by Warner et al. that were interpreted by some authors as raisi...

Discussions and Closures

The writers are congratulated for developing analytical approximations to Einstein integrals herein INT1 and INT2 . It was stated by the writers in their technical note that these algorithms can be incorporated into professional hydraulic software, and the discussers agree on this. However, it is pointed out here that the calculation of INT1 and INT2 can be easily incorporated more directly by ...

Discussions and Closures

The writer presents a parametric study devoted to investigate the behavior of nonprismatic members having T-sections by using three-dimensional ~3D! finite-element models ~FEMs!. Fixed-end moments and stiffness coefficients were computed from the 3DFEMs considering thrust effects. As a result of the parametric study, the writer proposed a practical modeling technique based on two-noded beam ele...

Subgraphs, Closures and Hamiltonicity

Closure theorems in hamiltonian graph theory are of the following type: Let G be a 2connected graph and let II, u be two distinct nonadjacent vertices of G. If condition c(u, u) holds, then G is hamiltonian if and only if G + MU is hamiltonian. We discuss several results of this type in which u and v are vertices of a subgraph H of G on four vertices and c(u, u) is a condition on the neighborho...
