Background: Most existing chemical experiment teaching systems lack solid immersive experiences, making it difficult to engage students.To address these challenges, we propose a chemical simulation teaching system based on virtual reality and gesture interaction.Methods: The parameters of Sports Bra the models were obtained through actual investiga
The losses of electricity in the electric grids of Iraq exceed 50%, which requires calculations and analysis of losses in grids of different voltage classes.The article provides a detailed description of the developed program for modeling the current Tool Cabinets modes of 132-400 kV networks according to SCADA data of the Iraqi National Dispatch C
In quantum nanoelectronics, numerical simulations have become a ubiquitous tool.Yet the comparison with experiments is often done at a qualitative level or restricted to a single device with a handful of fitting parameters.In this work, we assess the predictive power of these simulations by comparing the results of a single model with a large exper
One of the important devices to smooth the information asymmetry problem of the regulator is using "yardstick competition" The use of this mechanism has implications on the optimal division of a state-owned company before its privatization.We extend the framework introduced by Armstrong, Cowan and Vickers (1994) from 2 companies to n.The authors sh
Bacterial vaginosis is a common female disease caused by a vaginal infection due to an overgrowth of bacteria that naturally live in the vaginal tract.Bacterial vaginosis has frequently been treated with the oral or vaginal administration of antibiotics and topical disinfectants.However, hygienic application of topical treatment deep in the vagina
