Introduction Thermodynamic non-ideality can lead to serious problems in terms of the analysis of macromolecular behaviour in solution, particularly in molar mass and mass action measurements based on the principles of thermodynamic equilibrium. The term ‘molar mass’ (in g/mol) favoured by the physical chemist is of course equivalent to the molecular mass in daltons, and by ‘mass action’ we mean...

in this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. we have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. the spin-polarization parameter corresponding to the equilibrium state of ...

wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. to remove this problem, prediction of wax disappearance temperature (wdt) seems necessary. in this study, the pressure influence on the wax disappearance temperature...

It has long been established that for a Positive Displacement (PD) compressor or expander such as reciprocating or rotary screw type, the thermodynamic process is adiabatic when compressor or expander discharge pressure is equal to system back pressure (or 100% internal compression or expansion). At this design point, compressor or expander efficiency and noise are most desirable. But more ofte...

In this article, the optimized geometry, IR and UV spectra, frontier orbital analysis, natural bond orbital (NBO) analyses, and thermodynamic parameters of pomalidomide were investigated. The calculated structural parameters and stretching frequencies values are compared with experimentalvalues of the investigated compound. Also, the relations of the thermodynamic functions vs.temperatures were...

Thermodynamic retrievals can derive pressure and temperature information from kinematic measurements in regions where no in situ observations are available. This study presents a new retrieval technique called SAMURAI-TR (Spline Analysis at Mesoscale Utilizing Radar and Aircraft Instrumentation–Thermodynamic Retrieval) that derives three-dimensional fields of pressure and density potential temp...

Definitions of autonomous agents—simple living systems— have often included the thermodynamic idea that agents need to do work to construct constraints and to maintain these constraints. We show that an ant-pheromone system is sufficiently rich to allow an explanation of its behavior in terms of thermodynamic properties, particularly the work done by the system on itself to build structure. Thi...
