The prediction method of the isobaric vapor-liquid-liquid equilibria (VLLE) data for the system ethanol-water-1-butanol and ethanol-2-butanol-water was studied. The parameters for the activity coefficients models were determined from the constituent binary VLE data. With the parameters, the isobaric ternary VLLE data were predicted and compared with the experimental ones obtained in our previou...

Isospin symmetry is one of the fundamental symmetries we can identify in nuclei. This is related to the approximate charge symmetry and charge independence of the strong interaction. On this hypothesis, the level schemes of mirror nuclei (with exchanged number of protons and neutrons) should be identical. Of course some differences appear due to the fact that the Coulomb interaction breaks isos...

background: migraine is a prevalent disease which is classified into two groups of migraine with aura and without aura. eighteen percent of women and 6.5 percent of men in united states have migraine headache. migraine headache is prevalent in all age groups but it usually subsides in adults above fifty. migraine has many risk factors such as stress, light, tiredness, special foods and beverage...

(cerebrum, cerebellum, medulla, hippocampus and hypothalamus) was studied with respect to 1. Protein content 2. Reduced glutathione 3. Defense system enzymes like, superoxide dismutase. glutathione peroxidase and catalase 4. Lipid peroxidation levels 5. Acid phosphatase activity and 6. Ultra structure of brain (hippocampus region) to study the hypoxia imparted damagc. The present work also deal...

A traveling wave analysis for a quantum hydrodynamic model ist performed. The isobaric, isentropic and isothermal cases are studied. In all three cases the qualitative behaviour of the solutions is analysed.
