An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Mechanical plaque removal in step‐1 of care
Periodontology 2000, EarlyView., 2023 Abstract Maintaining a regular oral hygiene routine is essential for taking care of our mouths, ensuring healthy teeth, and achieving fresh breath. Patient education on oral hygiene is an important component of their overall treatment. Firstly, patients should be informed about the direct connection between bacteria in dental plaque and oral diseases ...
