Evolution Law of Wellbore Instability Risk under Fluctuating Pressure
Energies, 2023 The bottom hole fluctuating pressure has a large influence on the wellbore instability. To address this problem, firstly, according to the principle of seepage mechanics, we established a calculation model of the change in pore pressure around the ...

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

On Static Pressure Fluctuation between Sirocco Fan Blades in a Car Air-Conditioning System
Journal of Fluid Science and Technology, 2008 In this study, special attention is directed to static pressure fluctuation in a sirocco fan for a car air-conditioning system, because it is expected that there is a close connection between the fluid noise and the pressure fluctuation.

Fluctuation of Blood Pressure in a Patient With Pheochromocytoma
JACC: Case Reports, 2020 Treatment with a combination of norepinephrine and doxazosin was effective in a patient with pheochromocytoma who had blood pressure fluctuation, hypotension, and recurrent syncope. After adrenalectomy, his blood pressure, heart rate, and plasma levels of catecholamines remained normal and stable without any medication. (Level of Difficulty: Beginner.).
