Electrophoretic Capture of Circular DNA in Gels - A Review

August 1, 2002
Author(s)
B. Akerman, Kenneth D. Cole
Results on electrophoretic capture of circular DNA in porous gels are reviewed. Processes, which cause arrest of circular forms of DNA during electrophoresis, can provide a very efficient separation mechanism for the purification of plasmids and bacterial

The Cations and Anions of Cyclobutanetetraone Poly(Phenylhydrazones)

August 1, 2002
Author(s)
H S. El Khadem, M A. Shalaby, B Coxon
Six cyclobutanetetraone poly (arylhydrazones) have been treated with acids and bases, and the structures of the resulting anions and cations studied by UV/visible absorption and NMR spectroscopy. In acid media, all the hydrazones studied formed cations

The IUPAC Chemical Identifier

July 1, 2002
Author(s)
Stephen E. Stein, Stephen R. Heller, Dmitrii V. Tchekhovskoi
The author presented two talks at the IUPAC/CAS conference of Chemical identifiers and XML in Chemistry, on July 1, 2002 in Columbus Ohio. He will be sending powerpoint presentations of these talks, both concerning on-going projects at NIST, to IUPAC for

Free Radical-Induced Damage to DNA: Mechanisms and Measurement

June 1, 2002
Author(s)
M. Dizdaroglu, Pawel Jaruga, M Birincioglu, H Rodriguez
Free radicals are produced in cells by cellular metabolism and by exogenous agents. These species react with biomolecules in cells including DNA. The resulting damage to DNA which is also called oxidative damage to DNA, is implicated in mutagenesis

Liquid Agent Transport Around Solid Obstacles

May 1, 2002
Author(s)
Cary Presser, J F. Widmann, G Papadopoulos
The focus of this effort is to investigate the dispersal of liquid fire suppression agents around solid obstacles, and obtain a better understanding of the physical processes of droplet transport in cluttered spaces. An experimental investigation is

Biogenic Contributions to Atmospheric Volatile Organic Compounds in Azusa, California

April 1, 2002
Author(s)
George A. Klouda, C. W. Lewis, D C. Stiles, J L. Marolf, W D. Ellenson, W A. Lonneman
An objective of the 1997 Southern California Ozone Study (SCOS97) was to provide an up-to-date assessment of the importance of biogenic emissions for tropospheric ozone production in the South Coast Air Basin. To this end ambient air samples were collected
