2020/6/5
People living in low-income, disadvantaged communities across much of southern Los Angeles lack the means to cool their homes, posing a growing threat to their health -- and their lives -- from extrem...
Gas geochemistry for the Los Azufres (Michoacán) geothermal reservoir, México
Los Azufres geothermal field gas geochemistry geothermal gas equilibria reservoir exploitation
2015/9/10
Gas data of the Los Azufres geothermal field were analyzed using a method based on equilibrium of the Fischer-
Tropsch (FT) reaction: CH4 + 2H2O = 4H2 +CO2 and on the combined pyrite-hematite-magneti...

Atmospheric optical-turbulence at Roque de los Muchachos Observatory: database and recalibration of the generalized-SCIDAR data
Atmospheric effects? instrumentation: adaptive optics? Site Testing
2011/9/13
We present the largest database so far of atmospheric optical-turbulence profiles(197035 individual C2N(h)) for an astronomical site, the Roque de los Muchachos Observatory (La Palma, Spain). This C2 ...
Inter-community variability in total particle number concentrations in the eastern Los Angeles air basin
particle number the eastern Los Angeles air basin
2010/12/20
Ultrafine Particles (UFP) can display sharp gradients in their number concentrations in urban environment due to their transient nature and rapid atmospheric processing. The ability of using air pollu...
Intra-community spatial variability of particulate matter size distributions in Southern California/Los Angeles
Intra-community spatial variability particulate matter size distributions Southern California/Los Angeles
2009/3/13
Ultrafine particle (UFP) number concentrations vary significantly on small spatial and temporal scales due to their short atmospheric lifetimes and multiplicity of sources. To determine UFP exposure g...
Redox activity and chemical speciation of size fractioned PM in the communities of the Los Angeles-Long Beach harbor
Redox PM Los Angeles-Long Beach harbor
2008/11/25
In this study, two different types of assays were used to quantitatively measure the redox activity of PM and to examine its intrinsic toxicity: 1) in vitro exposure to rat alveolar macrophage (AM) ce...
