A Note on Predicting Rate of Penetration Using Machine Learning Models [PDF]

JES: Journal of Engineering Sciences
Rate of Penetration (ROP) is a critical parameter influencing drilling efficiency and accelerating field development. Although conventional ROP models (e.g., Bourgoyne, Hareland) provided reasonable results, they often struggle with limited accuracy and ...

Gabapentin supplemented with ropivacain block of trigger points improves pain control and quality of life in trigeminal neuralgia patients when compared with gabapentin alone [PDF]

, 2008
Objective: Pain control in trigeminal neuralgia (TN) is achieved using anticonvulsivants, mainly carbamazepine. When this drug cannot be used, other drugs like gabapentin (GBP) have been used to provide adequate pain control.

Enhanced Rheological and Filtration Performance of Drilling Fluids Using Fe3O4/Saponin/Cu(II) Nanocomposites: Synthesis, Characterization, and Application

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

Pentoxifylline dose finding trial in preterm neonates with suspected late onset sepsis (PTX‐trial)

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study (PTX‐trial) is to determine the optimal dose of pentoxifylline (PTX) in preterm neonates (gestational age < 30 weeks) with (suspected) late onset sepsis (LONS). Methods The PTX‐trial is a prospective multicentre open‐label sequential dose‐optimization study with an adapted continual reassessment method.
