Of voices few and far between: white Appalachian women migrants in postwar Chicago, 1950-70.

Oral history has been an indispensible tool in documenting the lives of those previously invisible from broad historical movements of people. "The Oral History Review" has been among the major vehicles for the inclusion of women's voices. The migration of white southerners is well documented in historical literature.

Study of the spin-spin interactions between the metal centers of Desulfovibrio gigas aldehyde oxidoreductase: identification of the reducible sites of the [2Fe-2S]1+,2+ clusters.

The aldehyde oxidoreductase from Desulfovibrio gigas belongs to the family of molybdenum hydroxylases. Besides a molybdenum cofactor which constitutes their active site, these enzymes contain two [2Fe-2S](2+,1+) clusters which are believed to transfer the electrons provided by the substrate to an acceptor which is either a FAD group or an electron-transferring protein. When the three metal centers of D.
