the equilibrium solubility data of co2 in the various aqueous blends of triisopropanolamine (tipa) + monoethanolamine (mea) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oc and co2 partial pressures below 100 kpa. the experiments were done in an atmospheric gas absorption system and the amount of absorbed co2 was measured wi...

background: we conducted a comprehensive bibliometrics analysis to calculate the h, g, m, a and r indicators for all iranian biomedical research centers (ibrcs) from the output of isi web of science (wos) and scopus between 1991 and 2010. we compared the research performance of the research centers according to these indicators.   methods : this was a cross-sectional and descriptive-analytical ...

let $g$ be a graph and let $m_{ij}(g)$, $i,jge 1$, be the number of edges $uv$ of $g$ such that ${d_v(g), d_u(g)} = {i,j}$. the {em $m$-polynomial} of $g$ is introduced with $displaystyle{m(g;x,y) = sum_{ile j} m_{ij}(g)x^iy^j}$. it is shown that degree-based topological indices can be routinely computed from the polynomial, thus reducing the problem of their determination in each particular ca...
