The Extended Hildebrand Solubility Parameter Approach (EHSA) is used to estimate the solubility of satranidazole in binary solvent systems. The solubility of satranidazole in various water-PEG 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility equation employs term interaction ...

Objective: The current work involves formulation development of nanostructured lipid carrier (NLC) eperisone hydrochloride (EPE) using quality by design (QbD) approach.
 Materials and Methods: Initial screening solid liquid lipids was performed based on the Hansen solubility parameters EPE later confirmed saturation studies. optimum identified three-squared randomized full factorial design...

this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

The solubility isotherm for CaHPO4 • 2H2O (DCPD) in the three-component system Ca(OH)2 — H3PO4 — H2O was determined in the pH range 3.5 to 6.8 by leaching a thermostated column of DCPD with dilute phosphoric acid solutions. In confirmatory experiments, equilibrium was approached both from superand under-saturation by shaking DCPD with appropriate solutions. The calculated ionic activity product...

Investigations were made concerning the number and properties of amylase in sugarcane leaves. Enzymes were extracted froin leaf samples which had been frozen, lyophilized, and ground to a fine powder. Techniques of differential solubihty, gel filtiation, and papei electrophoresis were employed to remove amylase from the crude extracts. Solubility studies showed that amylase was moderately preci...

Proteins of the same kind in human milk and cow's milk have different properties. Mellander (1947) reports differences in phosphorus content and the amount of carbohydrates of casein and that the casein of cow's milk is more easily digested by proteolytic enzymes in vitro than that of human milk. Kiyosawa, Ryoki & Maeno (1961) observed a marked difference in the solubility of casein and the tur...

Since monosodium urate (NaU) may play an important etiologic role in the formation of renal stones containing Ca in patients with hyperuricosuria, the current studies were undertaken to define some of the physiocochemical factors which determine the formation of NaU. In solutions containing Na, uric acid was rapidly transformed to NaU at pH greater than 6. The results indicated that NaU, and no...

objective: the purpose of this study was to evaluate the solubility of three luting cements in artificial saliva. materials and methods: twenty disks (10×4 mm) of polycarboxylate, zinc phosphate and glass ionomer cements were prepared according to manufactures’ instructions. after setting, they were desiccated and each ten specimens were immersed in artificial saliva with special ph (3 or 5), c...

the solubility of naproxen in binary mixtures of polyethylene glycol 200 (peg 200) + water at the temperature range from 298.0 k to 318.0 k were reported. the combinations of jouyban-acree model + van’t hoff and jouyban-acree model + partial solubility parameters were used to predict the solubility of naproxen in peg 200 + water mixtures at different temperatures. combination of jouyban-acree m...
