Nitrite concentrations were always Improved monitoring of non-CO2 greenhouse gases in air samples is presented, achieved using a new analytical system based on preconcentration, gas-chromatography and mass spectrometry.
In addition to the major HFCs, HCFCs and CFCs, the new observations include the first in situ time series of the C1–C3 PFCs (CF4, C2F6 and C3F8) and the more volatile of the HFCs (CHF3, CH2F2, CH3CF3) alongside SF6, all of which are now monitored routinely as part of the Advanced Global Atmospheric Gases Experiment (AGAGE).
Both kalkipyrone A and B showed moderate toxicity to Saccharomyces cerevisiae ABC16-Monster strain (IC50 = 14.6 and 13.4 mu M, respectively), whereas yoshinone A was of low toxicity to this yeast strain (IC50 = 63.8 mu M). Its structure, including stereochemistry, was determined by NMR, UV, and IR analysis and by GC-MS of the natural product and key derivatives.
The format of our upcoming conference is unusual for anthropology: instead of the usual, 15- to 20-minute paper in a panel, with multiple parallel panels, we’re opting for very short presentations to the whole assembled conference.
CDIP also plans to make all CDIP data available since 1975 accessible on the web.
Navigating the web site: At CDIP home page click on "data" for real-time conditions and links to historical data for select stations (in PNCERS area, Cape Mendocino and Grays Harbor buoys).
The Coastal Data Information Program (CDIP) database contains real-time and historical wave data dating back as far as 1975 for the coasts of California, Oregon, Washington, Hawaii, Georgia, Minnesota, Virginia and North Carolina.

A review of the hydrographic data from the 2002 Western Arctic Shelf-Basin Interactions (SBI) Process Cruises permits the following conclusions.
(1) Temperature-salinity relationships were similar to canonical descriptions, but at five stations in the outer shelf/slope region, warm/high-salinity Atlantic Layer Water appeared to have risen, displaced the lower halocline, and mixed with shelf/upper halocline water.
I’ll try to explain the logic, and my previous experience with speed presentations.
So often at conferences, the focus is on research that has already been conducted.
