Nonlinear analysis of an aeroelastic response generated on a flexible sheet under periodic aerodynamic excitation

This study presents a nonlinear analysis of the aeroelastic response of a cantilevered flexible sheet under periodic aerodynamic excitation. The aerodynamic excitation is generated by upstream excitation plates (oscillating thin and rigid plates). Periodically fluctuating flow is...

Awareness, knowledge, and utilization of Japanese physical activity guidelines among health fitness programmers in Japan

We conducted an anonymous online survey to clarify awareness, knowledge, and utilization of Japanese physical activity (PA) guidelines among certified Health Fitness Programmers who are specialists in exercise guidance for health promotion. Responses were obtained from 415 partic...

Identification and Characterization of Novel DPP-IV Inhibitory Peptides from Limnospira platensis Hydrolysates: Stability and Intestinal Permeability Evaluation

As the prevalence of type 2 diabetes increases rapidly, the demand for natural origin dipeptidyl peptidase-IV (DPP-IV) inhibitors with fewer side effects is increasing. In this study, protein-rich Limnospira platensis was investigated as a source of bioactive peptides to enhance...

Fundamentals of Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) and Safety Management of Chemical SubstancesPart 5 : Atomic Layer Deposition (ALD) Methods, Digital CVD Methods

Atomic layer deposition (ALD) methods are attracting attention because these can achieve surface reactions by chemically reacting only with raw material molecules adsorbed to solid surfaces. Two highly chemically reactive raw material gases are injected alternately, and a vacuum...
