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

INTUMESCENT “INSTANT FIREWALLS” FOR LOW-COST FIRE PROTECTION

January 1, 2002
Author(s)
Ginger Bennett
Intumescent materials respond to impingement of a fire by swelling and forming a protective char that physically and thermally protects the structure. Intumescent materials have been used (or investigated for use) in various military platforms for all

Investigation of Velocity Boundary Conditions in Counterflow Flames

January 1, 2002
Author(s)
W C. Park, Anthony Hamins
The effects of velocity boundary conditions on the structure of methane-air nonpremixed counterflow flames were investigated by two-dimensional numerical simulation. Two low global strain rates, 12 s-1 and 20 s-1, were considered for comparison with

Large-Scale Metrology - An Update

January 1, 2002
Author(s)
William T. Estler, K L. Edmundson, G Peggs, D H. Parker
Developments in large-scale engineering metrology since the 1978 report of Puttock are reviewed. Advances in optical technology and fast, low-cost computation have led to wide-spread use of laser trackers and digital photogrammetry for general-purpose

LIQUID AGENT TRANSPORT AROUND SOLID OBSTACLES

January 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
