Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Racism at Work: A Critical Qualitative Investigation
ABSTRACT An area of life that is profoundly impacted by anti‐Black racism is the world of work. Black Americans face persistent barriers from hiring to wage inequality to everyday mistreatment. In response, we conducted a critical qualitative investigation to explore how racism manifests in workplaces, uncover overlooked aspects of Black Americans ...

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam
This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

Performance evaluation of a pulsatile ventricular assist device under non physiologic pumping frequencies by means FEM and 2D approach [PDF]
A ventricular assist device (VAD) is a blood pump that works in parallel with heart. It is used as a mechanical assistance for patients that suffer cardiac insufficiency: as a therapy, as a bridge to transplant or to extend life.

Liquid Hydrogen Target Experience at SLAC [PDF]
Liquid hydrogen targets have played a vital role in the physics program at SLAC for the past 40 years. These targets have ranged from small "beer can" targets to the 1.5 m long E158 target that was capable of absorbing up to 800 W without any significant

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
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
