in this work, the solubility of nicotine extracted from tobacco leaves, found in the north of iran, in supercritical carbon dioxide has been measured. also the effects of pressure, temperature, extraction dynamic time, and the organic co-solvent on the amount of nicotine extracted from tobacco leaves have been investigated. it should be stressed that in order to reduce significantly the number ...

In order to investigate the NH3+H2O+LiBr (lithium bromide) absorption refrigeration cycle process and simulate it accurately, a vapor-liquid equilibrium calculation model was proposed obtain thermodynamic characteristic data of ternary mixtures. The parameters liquid phase is based on Wilson?s equation non-random two equation. vapor phase, assumed consist NH3 H2O only, described by Redlich-Kwon...

The importance of coprophagy in nutritional studies has long been recognized; already in the early days of vitamins numerous workers demonstrated the presence of B vitamins in the excreta of birds and mammals (cf. Kon, 1945; Elvehjem, 1948; Mickelsen, 1956) and began keeping experimental rats on screens to prevent their consuming their droppings. Rats kept in this way have been used for assays ...

A large eddy simulation (LES) and combustion instability analysis are performed using OpenFOAM for the multiple shear-coaxial injector combustor DLR-BKD (in German Deutsches Zentrum für Luft–Brennkammer D, Aerospace Center–Combustion Chamber D), which is a laboratory-scale operating in real-gas environment. The Redlich–Kwong–Peng–Robinson equation of state steady-laminar flamelet model adopted ...

Experience, defined as the subjective response of customers to any direct or indirect contact with a company, has been considered as a critical factor in connecting customers emotionally and in turn achieving customer retention. A most critical source of experience is the service delivery process encountered by customers. Nevertheless, existing tools for depicting service focus mainly on the ac...

Biomass fast pyrolysis process is a technology that converts renewable solids into dense liquid. This study aims to apprehend the thermodynamic behaviour of Intermediate Liquid Compounds (ILCs) observed during biomass pyrolysis. The system studied was closed (20 mL) with air and mixture solution five components (Acetic acid (AA), hydroxyacetone (HX), phenol; furfural (FF) methanol) at 90°C unde...
