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.

As a publicly funded institution,The University of Texas at Austin had to implement the state's legislation to allow concealed handguns on campus. Yet its own Campus Carry policy has sought to erase the matter from everyday campus life. The administration deems it a “nonissue,” presuming that students have become accustomed to the idea, do not think about it actively, and have a low interest in acquiring a handgun license. This paper, based on a survey of the university's undergraduates, questions these ideas. It shows that a majority of students think that the issue is important and examines in what sense the students are troubled by its effects. While opinions differ between supporters and opponents of Campus Carry, divergences also exist within their ranks, such as among supporters of the law regarding where guns should specifically be allowed at the university. On the basis of the survey, the essay also examines how many licensed carriers are actually on campus, compared to the university's estimates.
