The Phytochemical Society of North America will have its 50th anniversary meeting from December 10 through 15th, 2011, on the big island of Hawaii. The society has a long tradition in the study of plant biochemistry, chemistry, natural products (whether for commodity chemicals, food and fiber sources, renewable energy, pharmaceuticals, nutraceuticals and other bioactive substances). The meeting, being a very special celebration, is anticipated to attract a very broad range of researchers drawn from worldwide locations. This is also reflected in the international composition of our organizing and scientific program committees. We are now finalizing speakers for the PSNA 50 conference which has a variety of scientific themes, including biofuels/bioengineering, transcriptome profiling, metabolism and metabolomics, and new characterization technologies/methodologies. A most important part of our PSNA 50 conference is to provide opportunities for graduate students and postdoctoral fellows to present their research findings and exchange ideas with scientific colleagues. In this regard, the bulk of the funding in support of this conference is anticipated to come from sponsorships (industry, foundations, and so forth) and registrations which are currently underway. It is essential, however, that we strongly encourage the participation of both young graduate students and postdoctoral fellows at our historic …

These proceedings contain papers prepared for the 30th Monitoring Research Review: Ground-Based Nuclear Explosion Monitoring Technologies, held 23-25 September, 2008 in Portsmouth, Virginia. These papers represent the combined research related to ground-based nuclear explosion monitoring funded by the National Nuclear Security Administration (NNSA), Air Force Technical Applications Center (AFTAC), Air Force Research Laboratory (AFRL), US Army Space and Missile Defense Command, Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), and other invited sponsors. The scientific objectives of the research are to improve the United States’ capability to detect, locate, and identify nuclear explosions. The purpose of the meeting is to provide the sponsoring agencies, as well as potential users, an opportunity to review research accomplished during the preceding year and to discuss areas of investigation for the coming year. For the researchers, it provides a forum for the exchange of scientific information toward achieving program goals, and an opportunity to discuss results and future plans. Paper topics include: seismic regionalization and calibration; detection and location of sources; wave propagation from source to receiver; the nature of seismic sources, including mining practices; hydroacoustic, infrasound, and radionuclide methods; on-site inspection; and data processing.
