DNA Hydrogel Plugs Immobilized in Microfluidic Channels with Improved Stability

February 28, 2002
Author(s)
Rebecca A. Zangmeister, K G. Olsen, David J. Ross, Michael J. Tarlov
It has been previously demonstrated that DNA, modified on the 5' end with an acrylic acid group, can be incorporated into a polyacrylamide hydrogel matrix. These types of DNA containing gels have recently been immobilized in plastic microfluidic channels

Cell and DNA Standards for Medical Genetics Laboratories

February 1, 2002
Author(s)
Peter E. Barker
Standards have played a role in establishing human cytogenetic analysis as a clinical laboratory discipline from the beginning. Following implementation of basic cytogenetic techniques and discoveries of chromosomal disorders, scientific necessity inspired

Error Free Liquid Flow Diverters for Calibration Facilities (FEDSM2002-31085)

January 1, 2002
Author(s)
Tsyh Tyan Yeh, Aaron N. Johnson, Pedro I. Espina, N Yende
A design for diverter valves in gravimetric liquid flow calibration facilities is proposed. The concept makes use of repeated unidirectional motions of the diverter valve to reduce errors associated with asymmetry in the diverter valve motion and in the

Introduction To Serial Reviews On Oxidative DNA Damage And Repair

January 1, 2002
Author(s)
M. Dizdaroglu
Free radicals are produced in cells by cellular metabolism and by exogenous sources such as carcinogenic compounds, redox-cycling drugs and ionizing radiations. Reactive species cause damage to cells by reacting with molecules such as DNA, proteins and

The CCPN Project - An Interim Report on a Data Model for the NMR Community

January 1, 2002
Author(s)
R Fogh, W Boucher, E Laue, J Ionides, W Vranken, P Gliwa, J Thornton, E L. Ulrich, J Linge, Talapady N. Bhat, J Westbrook, H M. Berman, G L. Gilliland, M Habeck, W Rieping, M Nilges, J L. Markley
The Collaborative Computing Project for NMR (CCPN) was originally funded by the Biotechnology and Biological Sciences Research Council (BBSRC) in the UK along the lines of CCP4, a similar project for the X-ray community. It has three main aims: i) to

Turkish Population Data With the CODIS Multiplex Short Tandem Repeat Loci

December 1, 2001
Author(s)
B S. Akbasak, B. Budowle, D J. Reeder, J Redman, Margaret C. Kline
Allele frequencies for thirteen tetrameric short tandem repeat (STR) loci, CSF1PO, D18S51, D3S1358, D21S11, D5S818, FGA, D7S820, HUMTH01, D8S1179, TPOX, D13S317, VWA, and D16S539 were determined on 198 Turkish blood samples.

Crossover From First-Order to Critical Wetting: Short-Range Tricritical Wetting

October 22, 2001
Author(s)
David J. Ross, D Bonn, A I. Posazhennikova, J O. Indekeu, J Meunier
We study wetting in liquid mixtures of methanol and the n-alkanes. Mixing alkanes of different chain lengths, we can examine the crossover between critical (continuous) and first-order (discontinuous) wetting transitions. Measurements of the film thickness

Multispectral Probes for Materials and Chemical Analysis

October 1, 2001
Author(s)
Steven A. Buntin
High throughput experimentation is currently restricted by its limited ability to evaluate more than one parameter of a library at a time (e.g., chemical composition, dielectric constant, refractive index, surface roughness, phase , luminescence). When

Speed of Sound as a Thermodynamic Property of Fluids

September 15, 2001
Author(s)
Daniel G. Friend
In this chapter, we review the principles of sound propagation in fluid systems. From a study of the hydrodynamic equations, sound propagation is shown to be a wave phenomenon. The speed of sound then can be derieved at any state point from a knowledge of
