The endangered Mexican blindcat (Prietella phreatophila, Carranza 1954) is one of only four described stygobitic ictalurid catfish in North America. Members of two monotypic genera (Satan eurystomus and Trogloglanis pattersoni) are known from the Edwards Aquifer in Texas and, until recently, Prietella (represented by P. lundbergi and P. phreatophila) was only known to occur in Mexico (northern Coahuila to southern Tamaulipas). The recent discovery of P. phreatophila in a cave on the Amistad National Recreation Area in Val Verde County, Texas is the result of decades of sporadic effort on both sides of the US/Mexican border and has stimulated a renewed effort to investigate the distribution, ecology, evolutionary history, and conservation status of this species. Collaborative efforts among The San Antonio Zoo, The University of Texas at Austin, Zara Environmental, and The National Park Service are currently focused on habitat surveys in Texas as well as captive husbandry and propagation. Ongoing efforts with collaborators from the Comisión Nacional de Áreas Naturales Protegidas, Área de Protección de Recursos Naturales Sabinas and the Laboratorio de Genética para la Conservación, Centro de Investigaciones Biológicas del Noroeste, La Paz include expanded fieldwork in Mexico, hydrogeologic studies, and surveys using environmental DNA.

AbstractOver the last two decades, there has been a rapid expansion in the number of Taiwan programmes at universities in America and Europe; however, few of these Taiwan programmes have attempted to develop teaching courses. Where Taiwan courses have been introduced, they have tended to be in isolation and not well integrated into existing academic programmes. Among the universities with Taiwan programmes, only two have attempted to create comprehensive teaching programmes through which students can graduate with a degree in Taiwan studies: SOAS University of London and the University of Texas at Austin. The purpose of this paper is to compare the experiences of these two institutions in developing such niche teaching programmes. It begins with a discussion of how these two programmes first emerged and then goes on to review their distinct development trajectories and key features. The paper offers an analysis of how these two programmes were able not only to survive but also to expand their offerings and thrive in an academic environment that should be hostile to such niche programmes. It concludes with a review of the remaining challenges facing these teaching programmes.

This article highlights that pushing a refinery distillation column to its limits to meet heightened demand is a tricky undertaking that could result in an unwanted phenomenon called column flooding. As petroleum is distilled, various components of the crude oil remain separated from each other on porous trays inside the column. During a flood, butane, gasoline, asphalt, and other distilled crude oil products begin to commingle with each other inside the column. By knowing the actual beginnings of flooding, the operator knows how much he can push the column to distill more products. The flooding predictor will identify the incipient flood point regardless of the grade of crude oil and will provide the operator with information to reduce throughput when necessary. The US Department of Energy has awarded a cooperative research and development agreement to second point. The Motiva refinery in Norco has signed on as a partner to run the flooding predictor on a commercial-scale distillation column. Data from those tests will be fed into the ongoing work at the University of Texas.

The University of Texas at San Antonio (UTSA) has implemented a number of academic support systems to address obstacles to student success and to improve student retention. This paper describes the student demographics at UTSA, provides tracking data on student enrollment and retention, and includes discussion of the underlying causes of student attrition. It will describe some of the programs that are implemented to improve student success. Data is provided to measure the level of success of some of the programs that have implemented for the student success.
