ABSTRACT An estimated 3.4 million gallons of leaded gasoline, diesel fuel and other refined and unrefined products from buried pipeline systems and several refineries have affected a residential area of 200 plus homes and businesses. U.S. EPA tasked a consortium of energy companies to develop a rapid response program to quickly eliminate intermittent vapor intrusion problems and to ultimately remove the petroleum products plume. The project involved coordinating efforts between several energy companies, the U.S. EPA, the Illinois EPA, the Illinois Department of Public Health and ATSDR. Some of the innovative technologies utilized include the laser fluorescence Rapid Optical Screening Tool (ROST™), soil vapor extraction (SVE), oil skimming and bio slurping. Managing data decision uncertainties, through the compilation of historical data into a site conceptual model was used to develop a dynamic site cleanup strategy and managing rapidly evolving field data by GIS digital mapping and data collection systems.

Complex Crystal

It is well known that a standing electron wavefield can be set up in a crystal such that its intensity peaks at the atomic sites or between the sites or in the case of more complex crystal, at one or another type of a site. The effect is usually referred to as channelling but this term is not entirely appropriate; by analogy with the more established particle channelling, electrons would have to be described as channelling either through the channels or through the channel walls, depending on the diffraction conditions.

The control of form or shape inheritance can be approached by studying the morphogenesis of bacterial viruses. Shape variants of bacteriophage T4 with altered protein shell (capsid) size and nucleic acid (DNA) content have been found by electron microscopy, and a mutant (E920g in gene 66) controlling head size has been described. This mutant produces short-headed particles which contain 2/3 the normal DNA content and which are non-viable when only one particle infects a cell (Fig. 1).We report here the isolation of a new mutant (191c) which also appears to be in gene 66 but at a site distinct from E920g. The most striking phenotype of the mutant is the production of about 10% of the phage yield as “giant” virus particles, from 3 to 8 times longer than normal phage (Fig. 2).
