Solubility and mobility of PAHs in contaminated aquifers are discussed, evaluation of the potential use of humic acids as a remedial technology to enhance the solubility and biodegradation of residual PAHs. Wed, 10 Mar 2010 03:00:02 -0600 http://atecentral.net//index.php?P=FullRecord&ResourceId=11108 This Applied and Environmental Microbiology journal article (PDF) reports the discovery of group II introns in a bacterial mat sample collected from a deep-sea hydrothermal vent near 9°N on the East Pacific Rise. One of the introns was shown to self-splice in vitro. This is the first example of marine bacterial introns from molecular population structure studies of microorganisms that live in the proximity of hydrothermal vents. Wed, 10 Mar 2010 03:00:02 -0600 http://atecentral.net//index.php?P=FullRecord&ResourceId=11499 This website features Peter Franks, a Professor of Biological Oceanography at the Scripps Institution of Oceanography working in the Marine Life Research Group. He is a phytoplankton ecologist studying physical-biological interactions in the plankton, that is, how the physical processes in the ocean influence the growth and distribution patterns of phytoplankton. The panel at the bottom of the page links to descriptions of Peter's work, descriptions and animations from ongoing projects, and other useful web pages.

The page explains how tornadoes are classified, how they form, how their strength is measured, and why they are so destructive. Also included is an activity to model a tornado with water spinning in two plastic bottles.

The images in the gallery are divided into twelve differently names sets of images including “Flow around bodies,” and “Vortices.” Wed, 10 Mar 2010 03:00:02 -0600 http://atecentral.net//index.php?P=FullRecord&ResourceId=10623 This site offers a complete history of all missions to the moon. For each attempt there is a description of what happened along with some pictures. There is also interesting facts about the moon and descriptions of experiments done on the moon. Wed, 10 Mar 2010 03:00:02 -0600 http://atecentral.net//index.php?P=FullRecord&ResourceId=10676 This resource, part of the Spectroscopy Lab Suite, illustrates the physics of a semiconductor Diode Laser. Students can create conduction and valence band energy levels and build in a bias due to impurity doping. The basic processes for light emission, including external voltage bias and level transitions are shown. The band energy levels and internal and external bias can all be adjusted to achieve an output spectrum similar to the measured physical spectrum. Wed, 10 Mar 2010 03:00:02 -0600 http://atecentral.net//index.php?P=FullRecord&ResourceId=10682 This resource discusses the meaning of quantum wavefunctions in terms of measurement probabilities. The double-slit experiment is used to motivate the concept of probabilistic measurements. A shockwave applet is then used to allow students to explore the relationship between a 1D wavefunction and probabilities. Both the magnitude of the probability density and the probability in a finite interval in position can be displayed.
