The present invention relates to cell wall degradative systems, in particular to systems containing enzymes that bind to and/or depolymerize cellulose. These systems have a number of applications.

Disclosed herein is a purified toxin isolated from Euglena sanguinea. More specifically the toxin, termed euglenophycin, is an alkaloid having herbicidal and cytotoxicity against plant and mammalian cells.

A nanoporous insulating oxide deionization device, method of manufacture and method of use thereof for deionizing a water supply (such as a hard water supply), for desalinating a salt water supply, and for treating a bacteria-containing water supply. The device contains two composite electrodes each constructed from a conductive backing electrode and a composite oxide layer being an insulating oxide or a non-insulating oxide and an intermediate porous layer. The composite layer being substantially free of mixed oxidation states and nanoporous and having a median pore diameter of 0.5-500 nanometers and average surface area of 300-600 m.sup.2/g. The composite layer made from a stable sol-gel suspension containing particles of the insulating oxide, the median primary particle diameter being 1-50 nanometers. The difference in zeta potential, at a pH in the range of 6-9, being sufficient to suitably remove alkaline and alkaline earth cations (such as Ca.sup.2+ and Na.sup.1+), various organic and other inorganic cations and organic and inorganic anions from water, preferably household hard water. One composite layer being constructed from a mixture of Al.sub.2O.sub.3, MgAl.sub.2O.sub.4 and/or Mg-doped Al.sub.2O.sub.3 particles, and the other composite layer being constructed from SiO.sub.2 or TiO.sub.2.

Graphical depictions of the observed and forecast wind-driven waves for the Atlantic and Pacific Oceans adjacent to the coasts of the Continental United States (US) and extending south over the Caribbean Sea and the west coast of Central America. The gridded products are prepared for the initial wave heights and the 24 hour and 48 hour forecast wave heights in Gridded Binary (GRIB2) format.

This data from the National Weather Service provides Geographic Information System (GIS) graphical representations of tornados, large hail events, and damaging wind reports in the Continental United States for the period 1950 through 2006. The data provided are in .zip files that are generally around 50 MB. Although available to all, the data provided may be of particular value to weather professionals and students of meteorological sciences. An instructional manual is provided on how to build and develop a basic severe weather report GIS database in ArcGis and is located at the technical documentation site contained in this metadata catalog.

The National Weather Service (NWS) National Operational Hydrologic Remote Sensing Center (NOHRSC) provides comprehensive snow observations, analyses, data sets and map products. Available to all, these products specifically support a wide variety of government and private-sector applications in water resource management, disaster and emergency preparedness, weather and flood forecasting, agriculture, transportation, and commerce.

The National Weather Service (NWS) maintains historical Atlantic Ocean hurricane weather data in a format that can be exploited by Graphic Information System (GIS) software. Using KML/KMZ formats, it takes the numbers and words from the rows and columns in databases and spreadsheets and puts them on a map. This data file contains information about named and unnamed Altantic tropical storms and hurricanes from 1851 to 2006. Once downloaded, the file can be decompiled by decade and by year in a a KML/KMZ GIS viewer.

The National Weather Service (NWS) maintains historical Eastern Pacific Ocean hurricane weather data in a format that can be exploited by Graphic Information System (GIS) software. Using KML/KMZ formats, it takes the numbers and words from the rows and columns in databases and spreadsheets and puts them on a map. This data file contains information about named and unnamed Eastern Pacific Ocean tropical storms and hurricanes from 1949 to 2006. Once downloaded, the file can be decompiled by decade and by year in a a KML/KMZ GIS viewer.

The National Weather Service Storm Prediction Center (SPC) provides daily RSS feeds summarizing today's latest information about tornado and severe thunderstorm watches, mesoscale discussions, convective day 1-3 outlooks, and fire weather outlooks. Although available to all, the data provided may be of particular value to weather professionals and students of meteorological sciences.

The National Weather Service (NWS) Storm Prediction Center (SPC) routinely collects reports of severe weather and compiles them with public access from the database called SeverePlot (Hart and Janish 1999) with a Graphic Information System (GIS). The composite SVRGIS information is made available to the public primarily in .zip files of approximately 50MB size. The files located at the access point have organized severe weather data by County Warning Area (CWA). A CWA is a grouping of counties for which severe weather information is distributed. Although available to all, the data provided may be of particular value to weather professionals and students of meteorological sciences. An instructional manual is provided on how to build and develop a basic severe weather report GIS database in ArcGis and is located at the technical documentation site contained in this metadata catalog.
