Geosynthetics 2003 will be held 10-13 February 2003 at the Cobb Galleria in Atlanta. It will be a very different event than in the past. It will not be sponsored by NAGS but only by IFAI and GMA. The emphasis will not be on technical papers subjected to peer review but on "How to ---" sessions and the "proceedings" will be a book with different "How to ----" chapters written by invited practical experts. Dave Suits will be chairman of the conference. Exhibitors will have the opportunity to present their own mini-workshops/seminars. The conference will be heavily promoted internationally. Look out for further details in early September. Contact dfettig@ifai.com. This perhaps opens the door for NAGS and the Geo-Institute to introduce a more scientific geosynthetics conference.

High-Energy Treatment of Tubing & Molded Parts - E-Beam Services reports that plastic tubing and molded parts processed by means of the company's high-energy electron-beam process can replace more expensive engineered products in automotive under-the-hood applications. Such parts are said to exhibit outstanding performance and durability, as well as temperature and chemical resistance.E-Beam's high-energy process permanently alters the polymeric matrix by converting the material to a crosslinked polyethylene (PE) or PEX, the company explains. Utilizing electron beam technology, the process does not change product formulation or processing, E-Beam notes-unlike many thermochemical processing methods, electron beam crosslinking is performed on the fully formed component or product. Automotive design engineers can used this crosslinking process on HDPE tubing and molded parts to provide in-service temperatures as high as 120C, E-Beam says, noting that, in comparison untreated HDPE tubing normally withstands in-service temperatures of approx. 60C. In addition to improving performance temperatures, the process is also said to increase thermal stability under load. When tested at 80C, PEX tubing performs at 870 psi, while untreated HDPE tubing fails at 670 psi, according to E-Beam Services. Enhancements are also said to include increased tensile strength; increased impact resistance; improved resistance to slow crack growth and environmental stress crack; reduced rapid crack propagation; and improved resistance to oils, petroleum and solvents.

A new fast method for locating leaks in landfill caps uses a multi-channel IR analyzer (in conjunction with a GPS system) to monitor for methane, carbon dioxide, and non-methane hydrocarbons, several times per second A 15 acre landfill cap was surveyed on parallel tracks 5 ft apart in one day. https://www.geosynthetica.net/news/locating_leaks_in_landfills.asp
