The invention relates to a method for measuring the ratio of the volume flow rate of gas to the volume flow rate of a multiphasic hydrocarbon mixture. The gas and the liquid are sampled (A) in the pipe and measured in the flow. of mixing the ratio (αg) of the gas occupancy section...
Method of measuring pressure and/or molar mass of gas inside enclosure and measuring device FIELD: physics. SUBSTANCE: measurements are taken using an acoustic sensor having at least one transducer (5), an electrical system (8) connected to the transducer (5), and a connecting layer (6) for...
- Process and device for measuring the adsorption and optionally the desorption of a gas adsorbed by a solid sample and to its use. …<??>- More precisely, a drop in gas pressure, during the adsorption stage, or an increase in gas pressure, during the desorption stage, of 0.1 to 0.7Pa...
The dialyzed protein solution was filtered using a 0.22 μm Millipore filters. The equation (c = A410/εl) was applied to determine the protein stock concentration, where c, l, A410 and ε are concentration in a molar, path length of cuvette in centimeter (cm), absorbance at the ...
37. A sensor for measuring gas permeability of a test material, comprising: an electrically conductive sensing element that comprises a water and/or oxygen sensitive material, wherein the reaction of said material with water or oxygen when the sensing element is contacted with water and/or oxygen...
Surface casing vents divert natural gas migration along oil and gas boreholes to bypass groundwater, with the gas venting to the atmosphere. While this strategy is designed to protect groundwater, it constitutes a source of greenhouse gases to the atmosphere. In instances where gas leakage occurs...
We subtracted the molar volume of the cages from \(c_s^o(0)\) to determine the average number of irrotationally bound water molecules to the cage surface. Previous hydration studies found that potassium ions are not hydrated in solution31. Hence, we attributed all irrotationally bound water ...
The fuel gas or a substream of the fuel gas is passed through a volumetric flowmeter and the volumetric gas flow is measured. In addition, the pressure, temperature and the proportion of at least one
A major limitation in studying APT enzymes, however, is the lack of high-throughput assays to measure their activity. We have developed the first fluorescence-based assay, diacetyl benzene (DAB)-APT, for the measurement of APT activity using 1,2-DAB, which forms fluorescent conjugates with ...
Acidity. The pH scale was invented by Søren Sørensen in 1909. The organoleptic Scoville scale is used to rate the pungency of hot spices. Oven temperatures. Cooks may use gas marks or traditional descriptions. The Richter scale for earthquakes and other sudden energy releases. Volcanic...
