Traditional bottom-up energy models have been widely applied so far to assess the future energy technologies over a specific time horizon, quantifying the direct economic and environmental implications of future energy scenarios. However, such approaches ignore the interactions that the energy sector has with other sectors in the economy, hence failing in quantifying the global impact of future energy technologies. This study assesses the economic and environmental impact of an institutional energy scenario in the Egyptian economy, by soft linking a bottom-up, technology-rich model (OSeMOSYS) with a top-down Input-Output model (IOA). Based on the prospective institutional scenarios for Egypt, the energy model assesses the evolution of the Egyptian electricity mix towards 2040. Then, the future energy scenario has been applied to the IOA model in terms of change in energy technology mix, change in final demand of electricity and change in national GDP production. It is found that while primary energy consumption and GHG emissions of the energy sector are likely to decrease in the next decades, a significant increase in the same indicators for all the other national sectors is expected, thus unveiling the need to increase and diversify the energy efficiency investments in all the Egyptian economy.

Background: Small incisions, reduced pain, lower wound rates of infection, faster ambulation, and faster recovery are all benefits of laparoscopic ovarian cystectomy. Nevertheless, there are concerns regarding ovarian reserve in connection to the operative and hemostatic procedures utilized during the procedure. Aim of the work:To see how bipolar electrocoagulation and suture affected ovarian reserve following ovarian cystectomy. Patients and methods: Prospective observational randomized study included a sample of 50 women with ovarian cyst. Patients were randomly assigned to one of two groups: sutures (25 patients) or bipolar electro-coagulation (25 patients). All patients underwent ovarian cystectomy. Results: At three months following surgery, there has been no statistically significant difference in FSH levels between the suture group and the bipolar electro-coagulation group. While the suture group's mean FSH value was statistically lower than the bipolar electro-coagulation group's at 6 months after surgery. At 3 and 6 months after surgery, there has been no statistically significant difference in AMH between the suture group and the bipolar electro-coagulation group. At 3 and 6 months following surgery, there has been no statistically significant difference in antral follicle count (AFC) between the suture group and the bipolar electro-coagulation group. Mean value of AMH was statistically higher at day 3 of menstrual cycle than at 3and 6 months after the surgery among bipolar electro-coagulation group. Conclusion: FSH increased more in the bipolar electro cauterization group 6 months after surgery than in the homeostatic suturing group, possibly indicating more ovarian reserve loss in the former.
