piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. in the current research, using taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. the variables include type of solvent,...

Strong non-linearity combined with the complicated rheological behaviour of polymers makes the quality characteristics of products unpredictable in plastic injection moulding. The purpose of this work is to study the mechanical properties of injection moulded polypropylene/E-glass composites. The process parameters like the melt temperature, injection pressure, packing pressure and cooling time...

(Received: Feb. 24, 2013; Accepted in Revised Form: April 9, 2013) Abstract: Mycophenolic acid (MPA) is an antibiotic and immunosuppressive agent, as a secondary metabolite of Penicillium brevicompactum. Parameter optimization of culture composition using Test plan L16, available in the form of an orthogonal array and software for automatic design and analysis of the experiments, both based on ...
