Beyond Surfing: How the Web May Change Student Financial Aid

Two essential tools for\u27 anyone working with the World Wide Web are a crystal ball and a seat belt. The seat belt may keep you grounded in this fast-paced industry, but it may not help you keep your job. The World Wide Web is fundamentally changing how the world transacts business. The number of Web users rises daily; Internet traffic doubles every 100 days. The Web is becoming standard operating procedure for many businesses-from booksellers to mortgage companies. What about student financial aid? That is where a crystal ball will come in handy. Even the savviest Web consultants cannot tell you what the future will hold a year from now for any Web endeavor. The rate of technological change is staggering. In a couple of years, financial aid offices may implement new technology of which no one has yet dreamed. This article will attempt to do the impossible. By reviewing case histories from other industries and noting changes to the financial aid landscape, the next few pages should offer some order to the chaos brought on by rapid technological change and note some opportunities the Web may hold for the realm of student financial aid

Fabricating Functionally Graded Materials by Ceramic On-Demand Extrusion with Dynamic Mixing

Ceramic On-Demand Extrusion (CODE) is an extrusion-based additive manufacturing process recently developed for fabricating dense, functional ceramic components. Presented in this paper is a further development of this process focusing on fabrication of functionally graded materials (FGM). A dynamic mixing mechanism was developed for mixing constituent ceramic pastes, and an extrusion control scheme was developed for fabricating specimens with desired material compositions graded in real time. FGM specimens with compositions graded between Al2O3 and ZrO2 were fabricated and ultimately densified by sintering to validate the effectiveness of the CODE process for FGM fabrication. Energy dispersive spectroscopy (EDS) was used to compare final compositions to the original material designs. The specimen’s hardness at different locations along the gradients was examined by micro-indentation tests. The dimensions of sintered specimens were measured, and the effects of material composition gradients on the distortions of sintered FGM specimens were analyze

Tectonics and sequence stratigraphy of the Venezuelan Basin, Caribbean Sea

The central core of the Caribbean plate is the 3-4-km-deep Venezuelan Basin that is underlain by late Cretaceous oceanic plateau and oceanic crust. The Venezuelan Basin is obliquely subducted to the east-southeast beneath the continental South American plate at the east-west-trending South Caribbean deformed belt (SCDB), a 50-100-km-wide wedge of accreted sedimentary rocks. I have mapped the structure and sequence stratigraphy of five late Cretaceous to recent sedimentary sequences overlying a 230,000 km² area of the Venezuelan Basin. The dataset includes ~5900 km of 2D seismic reflection data acquired during five separate surveys from 1974-2004; these seismic data are tied to DSDP drill sites 146/149 and 150 which provide age and lithologic control on the interpreted sequences. I use these data to document older Cretaceous faults formed soon after the formation of the plateau and oceanic crust; to explain the along-strike variations in structural style of the actively subducting Caribbean plate; and to constrain the age and tectonic mechanism for the initiation of subduction along the SCDB. The earliest set of faults are normal faults, only affect rocks of Late Cretaceous age, and approximately parallel a set of seafloor-spreading magnetic anomalies described by previous workers. These normal faults are widely spaced in the area of smooth-topped lava flows making up the 15-km-thick oceanic plateau, but they are much more densely distributed in the area of abnormally thin (3-5-km-thick), rough-surfaced, oceanic crust in the eastern Venezuelan Basin. The faults are interpreted as the result of back-arc extension behind the Aves volcanic arc during the late Early to Late Cretaceous. Selective reactivation of inherited faults and new bending-related faults affecting late Cretaceous to recent sedimentary sequences strike east-west and parallel the trend of the SCDB. The age of the initiation of subduction at the SCDB has been determined based on the age of onlapping, wedge-shaped, sedimentary sequences in the Venezuelan Basin. Subduction began in the western Venezuelan Basin in the middle Eocene in the western study area, in the early Miocene in the central study area, and in the post-early Miocene-Recent in the eastern study area. The ages of subduction agree with a similar eastward younging in the age of folding and thrusting in northern South America. From this observation I infer that subduction of the Caribbean plate beneath the SCDB initiated as a backthrust response to collision between the Caribbean arc and the South American continent that began in the early Eocene and youngs in an eastward direction.Geological Science
