We have increased/decreased confidence in the magnitude and trend of emissions that are similar/different between these three estimates. For example, the largest differences between the three estimates occur in India and Indonesia, regions where there are relatively large emissions and relatively large ...
STAR smog check station, equipped with the latest testing devices, are ready to check your vehicle At idle an engine produces excess VOC/ HC because the engine cannot burn its fuel completely at low speeds. These emissions react with sunlight (photo-chemical smog) forming hundreds of compounds ...
Time- and size-resolved PM measurements are needed for testing mechanistic toxicological hypotheses, for characterizing the relationship between combustion operating conditions and transient emissions, and for source apportionment studies to develop air quality plans” [24]. Based on the accumulated ...
14.9, and 20.9% for B10, B20, and B30 blends, respectively, when compared to diesel engine emissions. Considering that the operating conditions during chassis dynamometer testing were very uniform, this reduction can be related to the increase in the percentage ...
and just tap your phone at the docking stations and as you get on the bus. Please do let me know your thoughts in the comments, I love this idea but I’m not in the bus industry so I realise I may be naively missing something. And if you are in the business of planning bus ser...
Simpson adds protecting the health of Fijians is also a major priority. He says vehicles that do not pass the emissions test will not be permitted to be used on the roads and a transition period will be established until full emissions testing begins to allow drivers to get their tailpipe ...
Random effects structure for confirmatory hypothesis testing: Keep it maximal. Journal of Memory and Language 68(3), 255–278, doi: 10.1016/j.jml.2012.11.001 (2013). 48. Funk, C. et al. The climate hazards infrared precipitation with stations—a new environmental record for monitoring ...
Shirmohammadi et al. (2018): PM0.25collected at the vicinity of Los Angeles Airport (LAX) and from central Los Angeles (LA) close to and downwind from major freeways, from stationary sampling stations used for air quality control, were investigated. The particles were subjected to source allocat...
Field and laboratory studies have been conducted to investigate the effect of surrounding buildings on the plume rise from low-level buoyant sources, such as distributed power generators. The field experiments were conducted in Palm Springs, California, USA in November 2010 and plume rise from a 9....
(2014) is applied to investigate the impact of mediating variables on the relationship between the DTA and ACEs. This testing process combines both stepwise regression and Bootstrap, and has been widely applied in mediating effect testing in in many fields such as technological innovation (Wang ...
