On Distribution Grid Optimal Power Flow Development and Integration
Due to changes in electric distribution grid operation, new operation regimes
have been recommended. Distribution grid optimal power flow (DOPF) has received
tremendous attention in the research community, yet it has not been fully
adopted across the utility industry. Our paper recognizes this problem and
suggests a development and integration procedure for DOPF. We propose
development of DOPF as a three step procedure of 1) processing the grid, 2)
obtaining a tractable solution, and 3) implementing multiple solution
algorithms and benchmarking them to improve application reliability. For the
integration of DOPF, we demonstrate how a DOPF federate may be developed that
can be integrated in a co-simulation environment to mimic the real-world
conditions and hence improve its practicality to be deployed in the field. To
demonstrate the efficacy of the proposed methods, tests on IEEE 123-bus system
are performed where the usage of tractable formulation in DOPF algorithm
development and its comparison to the benchmark solution are demonstrated
The value of anti-Müllerian hormone measurement in the long GnRH agonist protocol: association with ovarian response and gonadotrophin-dose adjustments
Follicle Stimulating Hormone and Anti-Müllerian Hormone per Oocyte in Predicting in vitro Fertilization Pregnancy in High Responders: A Cohort Study
Background: Follicle stimulating hormone (FSH) and Anti-Müllerian hormone (AMH) are utilized to differentiate between good and poor response to controlled ovarian hyperstimulation. Their respective roles in defining functional ovarian reserve remain, however, to be elucidated. To better understand those we investigated AMH and FSH per oocyte retrieved (AMHo and FSHo). Methodology/Principal Findings: Three-hundred and ninety-six women, undergoing first in vitro fertilization cycles, were retrospectively evaluated. Women with oocyte yields.75 th percentile for their age group were identified as high responders. In a series of logistic regression analyses, AMHo and FSHo levels were then evaluated as predictive factors for pregnancy potential in high responders. Patients presented with a mean age of 38.065.0 years, mean baseline FSH of 11.868.7 mIU/mL and mean AMH of 1.662.1 ng/mL. Those 88 women, who qualified as high responders, showed mean FSH of 9.766.5 mIU/mL, AMH of 3.163.1 ng/mL and oocyte yields of 15.867.1. Baseline FSH and AMH did not predict pregnancy in high responders. However, a statistically significant association between FSHo and pregnancy was observed in high responders, both after univariate regression (p = 0.02) and when adjusted for age, percentage of usable embryos, and number of embryos transferred (p = 0.03). Rate of useable embryos also significantly affected pregnancy outcome independently of FSHo (p = 0.01). AMHo was also associated with clinical pregnancy chances in high responders (p = 0.03

Biogat-fert technique for maximizing water and fertilizer units productivity for potato crop
Biogat-fert technique ensure to maximizing water and fertilizer unit productivity for potato crop, Two field experiments were carried out during growing seasons 2019-2020 and 2020-2021, at research farm of National Research Centre in Nubaria region, Egypt to study management of biogat-fert technique on potato crop under drip irrigation system in sandy soil conditions. Study factors were fertigation techniques (fertigation, biogat-fert and fertilizers). The following parameters were studied to evaluate the effect of study factors: (1) mineral and biological fertilizers effect of soil, (2) microbial number, (3) NPK ratio, (4) Yield of potato, (5) water use efficiency of potato, (6) Crop water production function. The results conducted that soil fertility was enhanced greatly in bio-fertilizer treatment. The average total N, total P and total K in 0–40 cm soil layers increased to 29.17, 26.67and 36.7% respectively. The average CFU of bacteria in soil layers increased by 15 Time. After drip irrigation, the CFU of bacteria had increased further, and reached more than 7.8× 107 CFU/g dry soil in the 0–40 cm soil layers. The results showed that the application of different bio-fertilizer along with fertilizers revealed significant positive impact on crop yield
