PubMed Central Canada: Beyond an Open Access Repository?
(Elsevier, 2013-01-01)PubMed Central Canada (PMC Canada) represents a partnership between the Canadian Institutes of Health Research (CIHR), the National Research Council's Canada Institute for Scientific and Technical Information (NRC-CISTI), ... -

Application of absolute principal component analysis to size distribution data: identification of particle origins
(Copernicus Publications, 2007)Absolute principal component analysis can be applied, with suitable modifications, to atmospheric aerosol size distribution measurements. This method quickly and conveniently reduces the dimensionality of a data set. The ... -
Simplified representation of atmospheric aerosol size distributions using absolute principal component analysis
(Copernicus Publications, 2007)Principal component analysis provides a fast and robust method to reduce the data dimensionality of an aerosol size distribution data set. Here we describe a methodology for applying principal component analysis to aerosol ... -
An inverse modeling procedure to determine particle growth and nucleation rates from measured aerosol size distributions
(Copernicus Publications, 2006)Classical nucleation theory is unable to explain the ubiquity of nucleation events observed in the atmosphere. This shows a need for an empirical determination of the nucleation rate. Here we present a novel inverse modeling ... -
Aerosol particle size distributions in the lower Fraser Valley: evidence for particle nucleation and growth.
(Copernicus Publications, 2004)Particle size distributions from 9 to 640nm diameter were measured at Eagle Ridge in the lower Fraser Valley from 13 August to 1 September 2001 as part of the Pacific 2001 Air Quality Study. The site was on top of a ridge, ... -
Determination of external and internal mixing of organic and inorganic aerosol components from hygroscopic properties of sub micrometer particles during a field study in the lower Fraser Valley
(Taylor & Francis, 2004)A tandem differential mobility analyzer (TDMA) system was developed to measure particle growth factors over a range of relative humidities from 50-85%. This system was deployed in the Lower Fraser Valley, and data was ... -
Laboratory studies of bromide oxidation in the presence of ozone: Evidence for glass-surface mediated reaction
(Springer Verlag, 2002)The reaction of sodium bromide particles in the presence of ozone was studied in a flow system both under dark conditions and with 254 nm radiation. We found that there was significant formation of gaseous bromine (probably ... -
Measurement of the coagulation rate constant for sulphuric acid particles as a function of particle size
(Elsevier, 2001)A new method for the determination of coagulation rate constants for monodisperse, neutral particles is described. In this method, a differential mobility analyzer (DMA) is used to prepare a monodisperse aerosol and a ... -
Observation of a SO2 induced nucleation event in the atmosphere
(Elsevier, 1998) -
A novel injector for low temperature flow kinetic studies
(American Institute of Physics, 1994)A new enclosed injector system for low temperature kinetic studies is described. This system offers a number of advantages over more conventional designs of moveable inlet injectors. The enclosed injector prevents the ... -
Aerosol growth and the condensation coefficient for water: a review
(Taylor & Francis, 1986)The transfer of gas phase species to aerosols depends critically on the condensation (or sticking) coefficient. Reported values for water on water vary from 0.03 to 1. Theoretical arguments indicate that the condensation ... -
Self-reaction of HO2 and DO2: negative temperature dependence and pressure effects
(Wiley-Blackwell, 1985)The negative temperature dependence, pressure dependence, and isotope effects of the self-reaction of HO2 are modeled, using RRKM theory, by assuming that the reaction proceeds via a cyclic, hydrogen-bonded intermediate. ... -
Optimization of a heat engine based on dissipative system
(American Institute of Physics, 1983)A new class of heat engine is analyzed in which the working fluid operates in a dissipative process, never in equilibrium. The conditions are found for stability and for the generation of work. Then the optimal path is ...
