Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

Flow-induced noise from a seal-vibrissa-shaped cylinder [PDF]

Journal of Sound and Vibration
Inspired by the special structure of seal vibrissae and their ability to effectively suppress vortex-induced vibrations, this paper studies the characteristics of flow and aerodynamic noise generated around a seal-vibrissa-shaped cylinder at a Reynolds ...

A Cappadocian Cylinder Seal

Iraq, 1967
As a small contribution to the volume of Iraq in honour of Professor Sidney Smith, I offer for publication a curious cylinder seal in the Kuiltepe style. This contribution, although inadequate, is at least fitting, because Professor Smith is well known for his contributions in this field. The seal illustrated on Plate III is in a private collection and
