Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT In chocolate‐coated products, oil migration can lead to chocolate softening and discoloration, filling hardening, and reduced consumer acceptance. This study examined three fats (soy‐, palm‐, and palm‐kernel (PK) based), crystallized under different conditions (cooling rate and high intensity ultrasound (HIU)) with differing oil binding ...

Experimental Examination of an Axial Compressor as a Basis for an Active Stall Avoidance System
International Journal of Rotating Machinery, 2000 A single-stage subsonic compressor was examined with respect to compressor instabilities. During the inception of rotating stall, the transients of the pressure rise and mass flow were measured as well as their hysteresis.

Gas Turbine Aerodynamics Improvement Via a Design of Intelligent Fractional Control
Journal of Mechanical Engineering, 2021 Gas turbines are complex processes characterized by the instability and uncertainty of various sources. The range of useful operating in an axial compressor which is part of a turbine gas is limited by aerodynamic instabilities that are surge and ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Analysis of Geometries' Effects on Rotating Stall in Vaneless Diffuser with Wavelet Neural Networks
International Journal of Rotating Machinery, 2007 Wavelet neural network (WNN), which combines the capability of neural network in learning from process and that of wavelet decomposition, was used to study geometry factors on rotating stall in vaneless diffusers.

Force stimulation promotes nerve regeneration by restoring cellular energy
BMEMat, EarlyView.Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

Observations of the Growth and Decay of Stall Cells during Stall and Surge in an Axial Compressor
International Journal of Rotating Machinery, 2017 This research investigated unsteady events such as stall inception, stall-cell development, and surge. Stall is characterized by a decrease in overall pressure rise and nonaxisymmetric throughflow.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how perceived overqualification (POQ) becomes a source of work alienation by focusing on interpersonal dynamics in the workplace. Drawing on relational and power‐based perspectives, we propose that abusive supervision serves as a key mechanism linking POQ to work alienation, while workplace ostracism conditions the strength

ECL5/CATANA: Transition from Non-Synchronous Vibration to Rotating Stall at Transonic Speed
International Journal of Turbomachinery, Propulsion and PowerNon-synchronous vibration (NSV), flutter, or rotating stall can cause severe blade vibrations and limit the operating range of compressors and fans. To enhance the understanding of these phenomena, this study investigated the corresponding mechanisms in ...
