The daytime oxidation of α-pinene in the presence of natural sunlight and oxides of nitrogen, NOx, was studied in a large outdoor smog chamber using gas chromatograph mass spectrometry as method of identification and quantification. A Scanning Mobility Particle Sizer system (3936, TSA) and a Co...
Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
Use of liquefied natural gas (lng) in a mass transit fleetThe Metropolitan Transit Authority of Houston, Texas, Harris County (Metro) began exploration for an alternative fuel in 1989. The decision to use LNG was made in October, 1990. This paper covers the experience gained in six years ...
0.71 g/LA sample of natural gas is 85.2% methane and 14.8 % ethane by mass. What is the density of this mixute at 18^(@)C and 784 mm Hg ?

Most structural and evolutionary properties of galaxies strongly rely on the stellar initial mass function (IMF), namely the distribution of the stellar mass formed in each episode of star formation1–4. The IMF shapes the stellar population in all stell
The measurement of natural gas is very important. Gas flow meters are widely used in industrial production processes, energy metering, environmental protection engineering, transportation, scientific experiments, etc. Gas Flow Meter Types At present, China's gas flowmeter products for natural gas flow...
It is most likely that these excesses have multiple origins, anthropogenic or natural or both. The comparison between RPM and deep-sea clay compositions emphasizes the prime influence of river input on oceanic sedimentation of Si, Al, Fe, Ti, lanthanides, Sc, Rb, V, etc. A few elements ...

gas phase at temperatures below 100°C cannot be separated and ionized using techniques other than GC/MS. Due to the ability to form stable, volatile derivatives of many compounds not suited for GC/MS in their natural forms, the number of possible analytes can be significantly expanded. ...
