Title: Analysis of Equilibria with One-Half Degree Defects for the Landau-de Gennes Model of Nematic Liquid Crystals Abstract: We investigate the structure of nematic liquid crystal thin films described by the Landau–de Gennes tensor-valued order parameter model with Dirichlet boundary conditions on the sides of nonzero degree. We prove that as the elasticity constant goes to zero in the energy...

Glutathione S-transferase expression in pollution-associated hepatic lesions of brown bullheads (Ameiurus nebulosus) from the Cuyahoga River, Cleveland, Ohio.

In rodents, overexpression of glutathione S-transferase pi is a characteristic feature of foci of cellular alteration (FCA) and neoplastic liver lesions induced by genotoxic chemicals. Alterations of glutathione S-transferase (GST) expression in hepatic lesions have also been reported in fish exposed to environmental carcinogens, and cellular GST expression may be an important determinant of gr...

Character and History of the Upper Ohio River Valley

Dismemberment of the preglacial Teays Valley system and development of the present Ohio River valley began in late Tertiary or early Pleistocene. By Illinoian time the present Ohio River was largely established in its present course, except for its headwaters above mile 114, which still flowed northward. The Illinoian glacial advance into northwestern Pennsylvania caused diversion of this porti...

Particulate air pollution and daily mortality in Steubenville, Ohio.

Particulate air pollution has been associated with daily mortality in London, England, both in the smog episodes of the 1950s and at the lower pollution levels of the late 1960s and early 1970s. Replicating these findings in the United States has been difficult, because particulates are usually sampled every sixth day. Replication, particularly with a gravimetric measure of particulates, is imp...
