A physical model can be used to judge cementing quality to help drilling engineering.This article reports a physical model based on Course a pied - Femme - Vetements - Chandail - Zip the XGboost algorithm to solve the cementing quality prediction problem of oil and gas wells.Through the physical model, the nonlinear, time-varying, and uncertain inf
Currently, research in nanoparticles as a drug delivery system has broadened to include their use as a delivery system for bioactive substances and a diagnostic or theranostic system.Nanogels, nanoparticles containing a high amount of water, have gained attention due to their advantages of colloidal stability, core-shell Multiminerals structure, an
Abstract Background Migraine is believed to affect over 20% of people at some point in their lives.The presence of sexual dysfunction in migraine sufferers can cause lack of self-confidence and divorces.The aim of this work is to study sexual dysfunction in migraine headache patients.Methods The study was carried out at Tanta University Hospital.Th
Abstract Under habitat loss and fragmentation, the intensity of local ecological processes involving species interactions changes pervasively, accelerating local species extinctions, and disrupting essential ecosystem functions.We addressed this issue by examining the direct population drivers of apex predators (five felid species), armadillo mesop
