A previously unknown radiation among flightless spring katydids (Tettigoniidae: Phaneropterinae: Brinckiella) in Western and Northern Cape provinces of South Africa is described. Seven species are described as new (B. aptera n. sp., B. arboricola n. sp., B. elegans n. sp., B. karooensis n. sp., B. mauerbergerorum n. sp., B. serricauda n. sp., and B. wilsoni n. sp.) and one species (B. viridis C...

Brazil, the Russian Federation, India, China and South Africa--the countries known as BRICS--represent some of the world's fastest growing large economies and nearly 40% of the world's population. Over the last two decades, BRICS have undertaken health-system reforms to make progress towards universal health coverage. This paper discusses three key aspects of these reforms: the role of governme...

Multiwavelength data on star-forming galaxies provide strong evidence for large-scale galactic winds in both nearby and distant objects. The results from recent ground-based and space-borne programs are reviewed. The impact of these winds on the host galaxies and the surrounding environment is discussed in the context of galaxy evolution.

At the end of the 20th century, the study of networks—systems of nodes connected by links—took off as scientists realized how ubiquitous they were. Complex networks describe interactions among proteins in a cell, coordinate communication among the neurons in our brain, and govern how individuals in a society connect. The list goes on. Many fundamental questions about networks remain unanswered,...

Norwegian Spring Spawning herring (NSSH) Clupea harengus L. spawn on coastal banks along the west coast of Norway. The larvae are generally transported northward in the Norwegian Coastal Current (NCC) with many individuals utilizing nursery grounds in the Barents Sea. The recruitment to this stock is highly variable with a few years having exceptionally good recruitment. The principal causes of...

A new plot for explaining the complex expression of the enzymic activity in reverse micelles has been developed as an extension of the theoretical model described by our group [Bru, Sánchez-Ferrer & García-Carmona (1990) Biochem. J. 268, 679-684]. The plot describes the changes in the relative volume, amount of enzyme (mumoles), enzyme concentration (microM) and substrate concentration (microM)...

Spam, defined as the transmission of bulk unsolicited messages, has plagued Internet email. Unfortunately, spam is not limited to email. It can affect any system that enables user to user communications. The Session Initiation Protocol (SIP) defines a system for user to user multimedia communications. Therefore, it is susceptible to Rosenberg, et al. Expires August 14, 2005 [Page 1] Internet-Dr...
