Dispersive liquid-liquid microextraction (DLLME) followed by gas chromatography-massspectroscopy (GC-MS) was used to analyses of components of floral-water of Rosmarinusofficinalis . Some effective parameters such as volume of extraction, disperser solvents andsalt effect were studied by a full factorial design for obtain the optimum condition. The maincompounds of the floral-water of Rosmarinu...

Abstract Wax deposition in production pipelines and transportation tubing from offshore to onshore is critical the petroleum industry due low-temperature conditions. The most significant popular approach solve this issue by inserting a wax inhibitor into channel. This research aims reduce amount of formation Malaysian crude oil estimating effective parameters using Design-Expert full factorial ...

Abstract Diet optimization is an important process to increase the efficiency of rearing insects and can be used develop high-quality with specific fitness life-history traits. Galleria mellonella (L.), greater wax moth, widely in research, microbiology assays, as pet food, host for biological control agents. Although artificial diets G. have been researched optimized decades, preliminary tests...

The computerization of method development and validation are useful in analysis of pharmaceuticals in pharmaceutical industry. In this article a simple and rapid high performance liquid chromatographic method has been developed for the determination of oxcarbazipine in pharmaceutical formulations. Factorial design was applied for optimization of essential factors for robustness study. A linear ...
