The connectivity index chi can be regarded as the sum of bond contributions. In this article, boiling point (bp)-oriented contributions for each kind of bond are obtained by decomposing the connectivity indices into ten connectivity character bases and then doing a linear regression between bps and the bases. From the comparison of bp-oriented contributions with the contributions assigned by ch...

in this study some thermodynamic parameters including freezing point, boiling point and the vapor pressure of urmia lake salt water were investigated as some important environmentally monitored physicochemical properties of urmia lake. in this regard salt concentration is chiefly responsible for the modification of the thermodynamic properties of urmia lake water which affects its overall envir...

Over 30,000 French scientists have signed an online petition to " save research " set up last month, with a pledge to stop their administrative duties unless the government starts listening to their complaints about funding. There is one signature for every minute that has passed since the petition — aiming to save the French public research base from the latest cuts imposed by the government —...
