An assessment of the efficacy and safety of balloon nephrostomy traction in minimizing postoperative bleeding of percutaneous nephrolithotomy: a randomized controlled clinical trial.

Purpose: Percutaneous nephrolithotomy (PCNL) as an established procedure for treatment of large kidney stones, can trigger life threatening complications. Postoperative hemorrhaging is one of the main complications of PCNL. This study investigates the effectiveness of balloon nephrostomy in reducing hemorrhage in the postoperative phase of PCNL.

Advancing sustainable lubricating oil management: Re-refining techniques, market insights, innovative enhancements, and conversion to fuel.

Lubricating oil disposal is considered hazardous waste and has adverse effects on the environment and human health. It is crucial to implement tight measures to regulate and minimize these impacts, or explore opportunities for oil regeneration. The paper offers an extensive review of worldwide demand for lubricating oil and its market share, with a specific emphasis on the viewpoint of Bangladesh.

Dose-dependent effects of transcranial photobiomodulation on brain temperature in patients with major depressive disorder: a spectroscopy study.

This study aimed to evaluate the dose-dependent brain temperature effects of transcranial photobiomodulation (t-PBM). Thirty adult subjects with major depressive disorder were randomized to three t-PBM sessions with different doses (low: 50 mW/cm, medium: 300 mW/cm, high: 850 mW/cm) and a sham treatment. The low and medium doses were administered in continuous wave mode, while the high dose was administered in pulsed wave mode.

Scaling-up dynamic elastic logs to pseudo-static elastic moduli of rocks using a wellbore stability analysis approach in the Marun oilfield, SW Iran.

Wellbore stability analysis is a critical component of petroleum engineering, evaluating the risks of sanding, reservoir compaction, and casing failures. Laboratory rock mechanical measurements must be scaled up to reservoir scales to achieve accurate results. One challenge lies in upscaling dynamic measurements from petrophysical logs to pseudo-static elastic properties, which has significant implications for oil and gas operations.
