The molecular weight characterization of heterogeneous polymer mixtures is complicated by the fact the molecular weight standards are often not available, or not appropriate, for a specific polymer. In cases [...]

As the creator of The Spirit, one of the original masked comic book heroes, Will Eisner established himself as a critical component of this uniquely 20th century art form. In [...]

Middle Tennessee populations of the Streamside Salamander, Ambystoma barbouri, delimit the southern extent of the species' range and are geographically isolated from more northerly populations. Few populations have been discovered in Tennessee, and all of them are located in the Inner Nashville Basin ecological subregion of the Interior Plateau. We surveyed for breeding activity in first- and second-order streams in the southern Inner Nashville Basin to determine the species distribution and to examine the status of and existing threats to extant populations. Streamside salamanders were found at five of 40 localities in southern Rutherford, northern Bedford and northeastern Marshall County, and at only 4 of 6 previously known breeding sites. Continued habitat fragmentation and alteration in association with the urbanization of Rutherford County threaten existing A. barbouri populations, which may represent the last remaining populations in the state. We recommend state and local agencies develop a habitat conservation plan to preserve and improve first- and second-order breeding sites and the surrounding forests used by adult Streamside Salamanders.

A comparison of accuracy between Multimodal magnetic resonance imaging (MRI) and Noncontrast computed tomography (CT) for detection of acute intracerebral hemorrhage in patients presenting with acute focal stroke symptoms is described. It is found that MRI is more accurate than CT for detection of chronic intracerebral hemorrhage.

Setting aside the ongoing ideological debates between the Democrats and the Republicans about who, if anyone, is entitled to what, if anything, it is easy to claim that we live [...]
