Generally, hydrocarbon derivatives oflow molecular weight, e.g., methane, ethane, and propane, are gases; those of intermediate molecular weight, e.g.,hexane, heptane, and octane, are liquids; and those of high molecular weight, e.g., eicosane (C20H42) andpolyethylene, are solids. Paraffi...
The simplest partition functions are obtained for monatomic and diatomic gases such as helium and nitro- gen. The partition function chosen by Flory for the polymer was obtained from contribu- tions by internal (i.e., intramolecular chemical-bond forces) and external (i.e., intermolecular ...
Based on this analysis, we found that resource of dewatered dewage sludge is involved in all levels except of the universe level (Fig.2). research for the coupling and correlation of biologic level and molecule and its gather state level should be the core problem in the complicacy multi-s...
Here we provide insights into the molecular signatures of eusociality within the termites. We analysed the genomes of two lower and one higher termite species and compared them to the genome of the German cockroach,Blattella germanica, as a closely related non-eusocial outgroup. Furthermore, differ...

strippers disposed between the annular film-forming elements on the inner surfaces of the reactor housing, the cylindrical rotor having a heatable portion, and at least one vapor pipe for the reaction gases, the at least one vapor pipe connected by a cone at a surface ratio of between about ...
Thus, a “substantially fluid-tight” seal includes a seal that prevents the passage of a fluid (including gases, liquids and/or slurries) therethrough when the seal is maintained at pressures of less than about 5 psig, less than about 10 psig, less than about 20 psig, less than about ...
The evolution of new species revolves around the natural as well as induced genetic variation created through revolutionary and conservative forces. Evolution and domestication are the two important phenomenon which occurred in nature, while domesticatio
and non-structural lightweight components in the construction industry [11]. The tree has a strong tolerance to air pollution and can help in its alleviation through its high capacity for absorbing greenhouse gases and other air pollutants. It is one of the most promising street trees for urban...
Water is also preferentially adsorbed over the so-called permanent gases such as carbon dioxide, nitrogen, oxygen and hydrogen. These FeAPSOs are therefore suitably employed in the drying of reformer hydrogen streams and in the drying of oxygen, nitrogen or air prior to liquifaction. The ...
