The solubility isotherms of CoCl2-H2O-CH3OH (C2H5OH) and NiCl2-H2O-CH3OH (C2H5OH) systems at 25 °C have been studied. Crystallization fields of the equilibrium existence of the salts CoCl2 . 6 H2O, CoCl2 . 2 H2O, CoCl2 . 2 CH3OH, CoCl2 . 2.5 C2H5OH, NiCl2 . 6 H2O, NiCl2 . 4 H2O, NiCl2 . 2 H2O, NiCl2 . 3 CH3OH and NiCl2 . 2 C2H5OH have been found. The dehydratation solubility processes of the studied systems have been discussed.

Saturated Solutions

The solubility isotherms of the M(NO3)2 - H2O - CH3OH (M = Sr, Ba) systems at 25 °C have been studied. Crystallization fields of the equilibrium existence of the salts Sr(NO3)2 .4 H2O, Sr(NO3)2 and Ba(NO3)2 have been found. The structures of the saturated solutions on the basis of statistic calculations and IR spectra have been discussed.

Solubility of several anthraquinone derivatives in supercritical carbon dioxide was readily available in the literature, but correcting ability of the existing models was poor. Therefore, in this work, two new models have been developed for better correlation based on solid–liquid phase equilibria. The new model has five adjustable parameters correlating the solubility isotherms as a function of temperature. The accuracy of the proposed models was evaluated by correlating 25 binary systems. The proposed models observed provide the best overall correlations. The overall deviation between the experimental and the correlated results was less than 11.46% in averaged absolute relative deviation (AARD). Moreover, exiting solubility models were also evaluated for all the compounds for the comparison purpose.

In this note, by using O. Hadzic's generalization of a fixed point theorem of Himmelberg, we prove a non - cooperative equilibrium existence theorem in non - compact settings and a generalization of an existence theorem for non - compact infinite optimization problems, all in not necessarily locally convex spaces.

In this paper, it will be studied stability for a SEIR epidemic model with infectious force in latent, infected and immune period with incidence rate. From the model it will be found investigated the existence and uniqueness solution  of points its equilibrium. Existence solution of points equilibrium proved by show its differential equations system of equilibrium continue, and uniqueness solution of points equilibrium proved by show its differential equation system of equilibrium differentiable continue.
