A simple visible spectrophotometric method is proposed for the determination
of ulipristal acetate present in bulk and tablet formulation. The currently
proposed method is established based on MBTH oxidation by ferric ions to
form an active coupling species (electrophile), followed by its coupling with
the ulipristal in acidic medium to form high intensiied green colored chromophore
having max at 609 nm. Validated the method as per the current
guidelines of ICH. Beer’s law was obeyed in the concentration range of 6.25 –
37.50 g mL1 with a high regression coeficient (r > 0.999). Reproducibility,
accuracy, and precision of the method are evident from the low values of R.S.D.
This method can be used in quality control laboratories for routine analysis of
ulipristal acetate in bulk drug and pharmaceutical dosage forms.

In most recent years, Egypt has been suffering from some grand challenges that disrupt its march of progress. Amongst all these challenges, the dilemma concerning water and agriculture has become worse than before and requires immediate resolution. Egypt depends on conventional water resources that face many problems due to over-consumption and pollution. The purpose of the study is to implement a practical solution related to treatment of wastewater and advanced irrigation water techniques. Therefore, it was decided to conduct an extensive research to find a suitable solution. By taking into account the prior solutions, it was obvious that the chosen solution, which is a urine treatment system provided with an Arduino based irrigation system, will be an ideal solution for water crisis in Egypt. A prototype was constructed with specific design requirements such as the quality of water and the efficiency of irrigation system. By testing the prototype, the results were more preferable than expected as it confirmed that the project fulfilled its design requirements. In conclusion, these promising results gave us a clue that this project will be so powerful on large scales in the near future.
