Floating matrix tablets of Glimepiride were developed to enhance its bioavailability by prolonging the gastric residence time in which Glimepiride was chosen as a model drug because of its has incomplete absorption due to its low gastric residence time. Floating matrix tablets were prepared using melt granulation technique. Bees wax was used as a hydrophobic meltable material. Hydroxypropylmeth...

The chemical step in the chemoenzymatic synthesis of bioengineered heparin has been examined and optimized statistically using a response surface methodology. A four factor, two level full factorial design experiment and a three factor Box-Behnken design were carried out. The goal was to establish a method to prepare N-sulfo, N-acetyl heparosan of the desired N-acetyl content, number average mo...

Application of excessive animal manure to the land may cause some environmental problems such as eutrophication of surface waters, degradation of ground water quality, and threats to human health. This paper reports an experimental study on the technology of biomass gasification to treat animal waste by analysing the effects of key operating parameters on gasification. In this research, dairy m...

Abstract The expanding proliferation of components for engineering applications requires greater optimisation parameters, which consequently increases the need more efficient boring practices. Taguchi Pareto-Box Behnken design is an effective procedure process parametric IS 2062 E250 steel plates. However, weakness method in its inability to distinguish parameters have effects on needs be furth...

Lemongrass (Cymbopogon citratus) is one of the plants as source essential oils, which are widely used food and beverage flavors aromatherapy. This plant has great potential to be developed due low prices high planting power. The extraction oils from lemongrass generally still uses conventional methods water distillation or steam distillation, requires a long time (about 6 hours) get good qualit...

In this study a novel High Performance Liquid Chromatography for the assay of nystatin in oral and vaginal tablets were optimized and validated using Box-Behnken experimental design. The method was performed in the isocratic mode on a RP-18 column (30 °C) using a mobile phase consisting of ammonium acetate 0.05 M buffer/ Methanol mixture (30:70) and a flow-rate of 1.0 mL/min. The specificity, l...

Objectives: The purpose of this research work was to formulate and systemically evaluate in vitro performances polymeric microspheres nifedipine. Methods: Nifedipine containing two polymers, poloxamer 407 carbopol 934, were prepared by single emulsion cross-linking technique. Glutaraldehyde selected as the agent. A Box–Behnken design employed study effect independent variables, polymer concentr...
