The Statistical Experimental Design techniques are the most powerful tools for the chemical reactors experimental modeling. Empirical models can be formulated for representing the chemical behavior of reactors with the minimal effort in the necessary number of experimental runs, hence, minimizing the consumption of chemicals and the consumption of time due to the reduction in the number of experimental runs and increasing the certainty of the results. Four types of nonthermal plasma reactors were assayed seeking for the highest efficiency in obtaining hydrogen and ethylene. Three different geometries for AC high voltage driven reactors, and only a single geometry for a DC high voltage pulse driven reactor were studied. According to the fundamental principles of chemical kinetics and considering an analogy among the reaction rate and the applied power to the plasma reactor, the four reactors are modeled following the classical chemical reactors design to understand if the behavior of the nonthermal plasma reactors can be regarded as the chemical reactors following the flow patterns of PFR (Plug Flow Reactor) or CSTR (Continuous Stirred Tank Reactor). Dehydrogenation is a common elimination reaction that takes place in nonthermal plasmas. Owing to this characteristic, a paraffinic heavy oil with an average molecular weight corresponding to C15 was used to study the production of light olefins and hydrogen.

Objective: To evaluate the quality of life in patients with endometriosis pelvic pain before and after the application of the levonorgestrel-releasing intrauterine system (LNG-IUS). Design: Open non-comparative study. Setting: Obstetrics and Gynecology Hospital at Monterrey, Mexico. Sample: 29 women aged 18 to 40 years with pelvic pain associated with endometriosis confirmed by laparoscopy. Methods: After laparoscopy but before LNG-IUS insertion (basal visit) and 6 months afterwards, modified Endometriosis Health Profile (EHP-30) was applied. Main outcomes measures: Size of change of questionnaire scores, need of additional analgesic therapy and adverse effects. Statistical Analysis: Differences in the questionnaire scores before and after intervention were analyzed by Student t-test. Results: Final analysis set included 29 women aged 31.7 ± 4.7 years years. The ASRM surgical staging of endometriosis was mild in 19.3 moderate in 13.7 and severe in 76% of the patients. The general perception of quality of life improved from 52 at baseline to 98% at six months (p < 0.001). Adverse events were mild in nature, 19 patients reported no adverse events during the study (65.5%). Two patients (6.9%) required the use of concomitant therapy with non-steroidal analgesics for relief of pain. Conclusion: The application of LNG-IUS in patients with pelvic pain associated with endometriosis improved significatively all aspects related with quality of life as measured with Endometriosis Health Profile (EHP-30). We concluded that LNGIUS may be an effective and convenient therapeutic alternative for the management of pain associated with endometriosis.
