Family Planning Perspectives even though penicillin has been an important and effective part of the public health campaign against syphilis and gonorrhea for more than 40 years, these STDs continue to be significant health problems. In fact, in some subgroups of the population, the incidence rates of these infections have risen dramatically.5 STDs persist in the U.S. population largely because ...

In this write-up, we extend quicksort to the task of fuzzy sorting of intervals. In many situations the precise value of a quantity is uncertain (e.g., any physical measurement is subject to noise). For such situations we may represent a measurement i as a closed interval [ai, bi], where ai ≤ bi. A fuzzysort is defined as a permutation 〈i1, i2, . . . , in〉 of the intervals such that there exist...

Heterobimetallic NiZn complexes featuring metal centers in distinct coordination environments have been synthesized using diimine–dioxime ligands as binucleating scaffolds. A tetramethylfuran-containing ligand derivative enables a stable one-electron-reduced S 1⁄4 1/2 species to be accessed using Cp2Co as a chemical reductant. The resulting pseudo-square planar complex exhibits spectroscopic an...

In this paper, from the perspective of spatial economics, we studied the spatial spillover of public services and their effect on factor income. We establish a Nonlinear General Equilibrium Model, which contains “two regions, two sectors and two elements". For the determination of the spill-over effect, using Matlab mathematical software to draw a furger, through the mathematical method of deri...

The text is clear and amplified by numerous illustrations but the bibliography, although considerable, lacks many important recent references. The English is excellent although terms such as dysoric retinopathy (page 87) might elude the most knowledgeable reader. This book obviously suffers from certain disadvantages when an ophthalmologist enters such a complex and changing field. There is thu...
