Very Large Photovoltaic Solar Power Plants (VLPVPPs) are a major revolutionary step up not only for economies of scale, but also for %100 renewable power Global Grid. Their designs and investments should be performed in an environmentally friendly, fair, open to very large to small private investors, transparent and reducing relative income inequality approaches. Their investments will easily be possible with new investment models (%0 interest load, %100 private equity, open investment for ordinary people, project developers, private companies etc. with a constraint-based shareholder structuring). These revolutionary investment models will play an important and game changing role. VLPVPPs' early engineering and investment analysis can be performed in many software. Therefore, validation and verification efforts of those software in advance on the operational PVPPs are essential. This research study aims to present a validation and verification accomplishment of the Solar Star Projects (597 MWAC, 747.3 MWDC) (Solar Star I: 318 MWAC, 397.8 MWDC & Solar Star II: 279 MWAC, 349.5 MWDC) in Antelope Valley near Rosamond, Kern and Los Angeles counties, California, United States with the PVWatts Version 5 model of the National Renewable Energy Laboratory (NREL) System Advisor Model (SAM) Version 2017.9.5. The location and resource, system design data and information on the Solar Star Projects (I & II) are presented based on open source information and personal communications. The Solar Star Projects SAM software models' are simulated on a personal computer (PC) (Windows 10 Pro, Intel(R) Core(TM) i5 CPU 650 @ 3.20 GHZ, 6,00 GB RAM) with the internet connection. The results of eight simple simulations, one parametric simulation and one stochastic simulation are compared with the actual generation data by the help of some statistical performance measures (e.g. annual model/actual: 100,0%, annual model/actual: 100,1%, absolute maximum forecast error 39.276 MWh, mean absolute error 11.554 MWh, geometric mean absolute error 8.924 MWh, mean square error 2.662.330.229 MWh, root mean square error 51.597 MWh).

Background Penile skin inversion vaginoplasty is a gender-affirming surgical procedure for transwomen with limited surgical analgesic protocol. This study compares the postoperative pain and opioid use in patients managed for surgery with general anesthesia (GA) with patients who were given combined epidural and general anesthesia (E/GA) with continuing postoperative epidural analgesia. Methods All patients who underwent penile inversion vaginoplasty between May of 2016 and May of 2018 under the care of single surgeon were identified retrospectively, 18 patients of which met the inclusion criteria. A retrospective chart review was conducted. Outcome measures were postoperative pain using visual analog scale, type and dosage of postoperatively administered intravenous or oral opioids (converted to morphine milligram equivalents, duration of inpatient admission, and time to ambulation. Results Patients who received combined E/GA reported significantly less pain and used less opioids during the first 4 postoperative days in comparison with patients who received GA alone. The reduction in mean pain associated with the use of an epidural was found to be statistically significant (P < 0.0005) as was the difference in opioid used in the 2 groups (P < 0.005) over the first 4 days postoperatively. Differences in day 5 pain suggest that postoperative pain is significantly lower even after the epidural has been removed (P < 0.005). There was no significant difference in length of hospital stay and time to ambulation (P > 0.05). Conclusions Combined E/GA was associated with decreased inpatient opioid consumption after surgery and provided superior pain control than administration of GA alone. Based on these findings, combined E/GA should be strongly considered for patients undergoing penile inversion vaginoplasty.

Objective: Postpartum period is physically, socially and emotionally a difficult time for the parents and the baby to become a family. We tried to investigate how the anaesthesia method affects patients who underwent cesarean delivery, as a factor which also affects this period. Methods:Two hundred and six parturients, who underwent elective cesarean delivery in Celal Bayar University Hafsa Sultan Hospital were recruited for our study. After demographic data and anaesthesia methods were noted, an EQ-5D health survey and Katz ADL scale were evaluated face to face 24 hours postoperatively, and by telephone on the 5th postoperative day. Results:The percentage of patients who had general anaesthesia was 35.2% (n=71), while 19.8% (n=40) had epidural anaesthesia and 45% (n=91) had spinal anaesthesia. Among -these three methods, the EQ-5D health survey revealed that the outcome at postoperative 24 hours was best in epidural anaesthesia and that general anaesthesia outcome was the worst (p=0.007). The Katz ADL scale at postoperative 24. hours showed that epidural anaesthesia was better than the other methods for regaining daily life activities (p<0.05). Conclusion:Our study showed that epidural anaesthesia had the most effective role among the methods in regaining daily life activities after elective cesarean delivery, which was demonstrated using the EQ-5D health survey and Katz ADL scale.Key Words: Cesarean sectio, anaesthesia, quality of life Abstract Introduction
