Abstract: A method for making a superconducting article includes the steps of providing a biaxially textured substrate. A seed layer is then deposited. The seed layer includes a double perovskite of the formula A2B?B?O6, where A is rare earth or alkaline earth metal and B? and B? are different rare earth or transition metal cations. A superconductor layer is grown epitaxially such that the superconductor layer is supported by the seed layer.

Abstract: This invention relates to an imaging system useful in medical and industrial x-ray imaging, including classical and digital radiography, and classical CT scanning. The imaging system of the present invention provides an increased spatial resolution over imaging systems of the prior art by angulating an x-ray detector or detector array with respect to a radiation source.

Abstract: A multilayered nonwoven composite web particularly useful as a substitute for a woven web such as a textile web, and having improved liquid wicking and retention properties comprising a first layer of fibrous material selected from the group consisting of thermoplastic meltblown man-made fibers, thermoplastic spunbonded man-made fibers, thermoplastic man-made staple fibers and combinations thereof, this first layer being light weight, and a second layer of cellulosic-based fibers, preferably cotton fibers, the first and second layers being thermally bonded together over about 5 to 75% of the surface area of the web to form a coherent web having an air permeability of between about 25 and about 37 ft.sup.3 /min/ft.sup.2 (0.127 and 0.188 m.sup.3 /sec/m.sup.2). In a preferred embodiment, the composite web includes at least a third layer of thermoplastic man-made fibers and the layer of cellulose-based fibers is sandwiched between the two layers of thermoplastic man-made fibers.

Abstract: N-2-chloroalkyl nitrosouredio derivatives of anthracycline-based compounds having antitumor activity are disclosed. Relative to the clinically-used drugs adriamycin and daunorubicin, substantially enhanced antitumor activity against parent murine P388 leukemia and an adriamycin-resistant P388 leukemia subline has been found for the N-2-chloroethylnitrosoureido derivatives of adriamycin, daunorubicin and epirubicin. Chemical stability has been found to be enhanced when employing the 4'-epi stereoisomeric family of these compounds.
