A Novel Manually Operated Compression Device for the Prevention of Deep Vein Thrombosis
… inexpensive device that could apply therapeutic compressive pressure to the lower leg to aid in the prevention of deep vein thrombosis using only mechanical input from the user. Several different prototypes were designed and built with varying degrees of success. Characterization of the final …

Design of an omnidirectional soft tactile sensor with applications in leak detection
… of the material: uniaxial tension, bending, compressive pressure, and torsion. Furthermore, this sensor is well-suited for the detection of leaks, obstacles, and pipe joints in active water pipes.

Effective Thermal Properties of Granular Porous Media: A Numerical Study using Lattice Blotzmann Methods
… surface profile of the grain. Furthermore, the compressive pressure and presence of different fluids in the pore space along with partial saturation can also dictate the nature of the effective thermal properties. To study the effect of all these factors on the effective thermal conductivity of …

Failure analysis of a 30kHz ultrasonic welding transducer
… high frequency mechanical vibrations and compressive pressure are applied to the plastic materials. This creates intermolecular friction within the plastic which raises the temperature high enough to reach the melting point. During high volume production in manufacturing environments, the …

Nonlinear Viscoelastic Wave Propagation in Brain Tissue
… waves is possible inside the head in response to compressive pressure waves from blast explosions. Furthermore, it was argued that injury to the nervous tissue at the microstructural level could be attributed to the high stress and strain gradients with high temporal rates generated at the shock …

Hydrocyclone fractionation of chickpea flour and measurement of physical and functional properties of flour and starch and protein fractions
… or deionized water. In both media, high inlet pressure resulted in smaller geometric mean diameter of particles collected in the overflow and underflow. Isopropyl alcohol as a medium resulted in particles with smaller geometric mean diameter than did deionized water. Starch and protein …

Understanding the Impacts of Ammonia Fiber Expansion (AFEX™) Pretreatment and Densification on Densified Products Quality and the Bioproducts Yield Through Enzymatic Hydrolysis and Fast Pyrolysis
… with liquid ammonia at moderate temperature and pressure. The impacts of AFEX™ pretreatment include cellulose decrystallization, hemicellulose hydrolyzation, and lignin depolymerization. Due to these alterations, the cellulose and hemicellulose components can be easily accessed by the enzymes …
