In the immiscible blends of poly(phenylene sulfide) (PPS) and polyarylate (PAR), absorbed moisture partitioned into each phase according to the equilibrium value of the homopolymers. The water diffusivity was observed to decrease with increasing PPS

Melt-extruded and subsequently injection molded polysulfone (PSF) and poly(phenylene sulfide) (PPS) blends exhibit very good tensile properties, at least up to 30–50% by weight of PPS. The tensile strength at the lower PPS contents shows additive e

Adenocarcinoma of the mammary gland is the leading type of cancer in women. Among these breast cancers those that are estrogen-responsive respond well to existing therapeutic regimens while estrogen non-responsive cancers metastasize widely, demonstr

Pulmonary adenocarcinoma (PAC) is the leading type of lung cancer and is highly resistant to conventional cancer therapy. A better understanding of the regulatory mechanisms which control the growth of this deadly malignancy are urgently needed to de

Differences between transformed cells and their normal counterparts were defined by analyzing the cells' three-dimensional distribution of mass. Variables called factors, which explained the covariance of the real variables, were extracted from the d

The receptor tyrosine kinase c-kit is necessary for normal hematopoiesis, the development of germ cells and melanocytes, and the pathogenesis of certain hematologic and nonhematologic malignancies. To better understand the regulation of the c-kit gen

Relative to their normal counterparts, transformed epithelial cells have a distinctive and quantifiable three-dimensional shape. Biophysical and mathematical methods are used to distinguish these extremes in cells from two lines, cultured from rat li

Films of Co/SiO2 composites were prepared by sequential sputtering from Co and SiO2 targets in Ar. As-grown films as well as films annealed in H2/N2 atmospheres consist of hcp Co particles of uniform size embedded in the SiO2 matrix. The measured opt

Aluminum automotive wheels, which have been used since the mid 1970’s, have proven to be very rugged, but early wheels discolored with time. Since 1976 the machined “bright” exterior surfaces, have been coated with a chromium based “conversio

Much of the work reported in the literature on the morphology of cellulose acetate reverse osmosis membranes has been hampered by a lack of specimen contrast or the presence of artifacts introduced during sample preparation. In this study the morphol
