Time-domain measurement of fluorescence lifetime variation with pH
(Society of Photo-optical Instrumentation Engineers, 2001)
Advances in the design and miniaturization of the lasers and electronics required for Time Correlated Single Photon Counting (TCSPC) measurement of fluorescence lifetime have simplified the use of the time domain method. ...
Monte Carlo simulations of liquid crystals between microstructured substrates
(American Institute of Physics, 2008)
The structure of a model liquid crystalline fluid confined between two microstructured substrates is studied through Monte Carlo simulations. A simple model for a structured substrate, similar in spirit to those used for ...
Fluorescence emission from petroleum; a valuable information source for petroleum analysis.
(EniTecnologie, 2004)
Despite the fact that most crude oils are dark coloured liquids, many are observed to be strongly fluorescent when illuminated with UV light. This fluorescence, which originates from the presence of aromatic compounds, is ...
Analysis of hydrocarbon bearing fluid inclusions HCFI) using time-resolved fluorescence spectroscopy
(Society of Photo-optical Instrumentation Engineers, 2005)
Hydrocarbon-bearing fluid inclusions (HCFI) are microscopic cavities within rocks that are filled with petroleum oil, the
composition of which may not have changed since the trapping event. Thus, the composition of that ...
Influence of chemical composition on the fluorescence lifetimes of crude petroleum oils
(Society of Photo-optical Instrumentation Engineers, 2003)
Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low
cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the ...
A quiver presentation for Solomon's descent algebra
(Elsvier, 2009)
The descent algebra S(W) is a subalgebra of the group algebra of a finite Coxeter group W, which supports a homomorphism with nilpotent kernel and commutative image in the character ring of W. Thus S(W) is a basic algebra, ...
Multiwavelength Observations of Markarian 421 in 2005 - 2006
(2009)
Since September 2005, the Whipple 10m Gamma-ray Telescope has been operated primarily as a blazar monitor. The five Northern Hemisphere blazars that have already been detected at the Whipple Observatory, Markarian 421, ...
Observation of gamma-ray emission from the galaxy M87 above 250 GeV with VERITAS
(2008)
The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in Active Galactic Nuclei from radio waves to TeV gamma-rays. Here we report the detection ...
VERITAS Discovery of >200GeV Gamma-ray Emission from the Intermediate-frequency-peaked BL Lac Object W Comae
(2008)
We report the detection of very high-energy gamma-ray emission from the intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS. The source was observed between January and April 2008. A strong outburst ...
