ρgas= density of gas (kg/m3) ρair=density of air(normally at NTP - 1.204 (kg/m3)) NTP - Normal Temperature and Pressure- defined as20oC (293.15 K, 68oF)and1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) ...
NATURAL gasLATEXPhysicochemical regularities are studied for the synthesis of molded active carbons based on coconut shells and peat, with a latex emulsion and a carboxymethyl cellulose (CMC) sodium salt solution being used as binding agents. The materials are obtained at compacting pressures of 25,...
We tested this hypoth- esis by removing two, four or six uppermost leaves from top of a plant at three days after silking, with no-leaf removal as control, to understand whether higher N accumulation in kernels of maize at high density could be achieved through optimum leaf removal, to ...
The populations of these disynaptic basins indicate some delocalization of the electron density of the C4–C5 double bond at the sulfur S6 atom. The analysis of the natural atomic charges [39,40] shows that the two carbons of AY 22 are negligibly charged by less than ±0.1 e. ...

4. Production of DVS Starter of Lactobacilli Fermented food has experienced the methods of natural fermentation, inoculation fermentation, and pure culture fermentation, that is, a directed vat set (DVS) starter de- veloped today [189]. A DVS starter has a stronger fermentation activity and ...
F10.7 is determined by the average of the intensity of solar radio emission in the 100 MHz bandwidth centered at 2800 MHz (the wavelength is 10.7 cm) over an hour. The unit of F10.7 is sfu, and 1s f u = 1022 W/ m2·Hz . Since the solar activity has a huge influence on the ...
At the end of the 20th century, based on the theorems by Hohenberg and Kohn, a new theory to study the electronic structure of the matter, known as Density Functional Theory (DFT) [19], in which the ground state (GS) energy of a nondegenerated N electron system is only a functional ...
Since there is only one stable configuration for H adsorbed at the fcc sites on Pt(111) which has been proved by both experimental and theoretical results, what is the main reason leading to the two peaks? Which factors do determine the peak position and area of H2 TDS spectra? Are the ...
It is found that although the grain size of RTM and LTB specimens is almost the same, different types of nano-twins have been produced. Moreover, the effect of RTM and LTB processing on high temperature oxidation behavior of nickel-based superalloy GH738 at 700 ◦C is investigated. The ...
