Weingarten cautions against equating R&D spending too closely with innovation, noting that many oil and gas companies fare poorly under such measurements because of Statistics Canada's criteria for research spending, but still frequently develop new methods and ideas.
The measurement method using the harmonic interferometer that we have developed does not depend upon gas composition used when plasma is produced, as compared to other electron density diagnostic methods for atmospheric pressure low - temperature plasma.
Using this method that has been developed by high - temperature plasma diagnostics, as shown in Image 2, we have succeeded in greatly reducing the influence of atmospheric pressure (gas), which was a problem in high - accuracy measurement of atmospheric pressure low - temperature plasma.
«Air quality measurements: New manufacturing method for nano gas sensors opens doors.»
In contrast, the method used by Miller and his colleagues, called a top - down method, uses measurements of methane in the atmosphere, taken from a national network of greenhouse gas monitoring stations and aircraft measurements conducted by the National Oceanic and Atmospheric Administration and the Department of Energy.
The installation of the gas reservoirs, which are located in the rear and underneath the front passenger footwell, reduces the boot capacity of the B ‑ Class by 128 to 422 litres (as per the VDA measurement method), but there is still sufficient space for carrying a family's luggage.
The lines of evidence and analysis supporting the mainstream position on climate change are diverse and robust — embracing a huge body of direct measurements by a variety of methods in a wealth of locations on the Earth's surface and from space, solid understanding of the basic physics governing how energy flow in the atmosphere interacts with greenhouse gases, insights derived from the reconstruction of causes and consequences of millions of years of natural climatic variations, and the results of computer models that are increasingly capable of reproducing the main features of Earth's climate with and without human influences.
The analytical methods for routine CO2 measurements used at the University of Bern and at LGGE in Grenoble are based on dry extraction techniques followed by laser absorption spectroscopy and gas chromatography, respectively.
Various methods collect data at different scales: Chamber measurements collect data over square - meter areas, tall towers and aircraft observe larger areas, and satellites (e.g., Greenhouse Gases Observing Satellite, or GOSAT) observe areas larger than a square kilometer.
