This study was conducted to determine if VO, of stepping in children is affected by altering the step platform height based on leg length. The effect of leg length on VO, and heart rate (HR) during stepping was examined in 19 children, ages 8-17, who stepped onto 5 different bench heights that corresponded to hip angles of 65", 73", 82", 90°, or 98". VO, and HR response to a work load of 8 m . ...

Measured vertical gravity gradients usually quite differ from the normal value of 0.3086 mGal/m (1mGal = 10ms). Generally the changing of vertical gradient is rather big, up to a few 10 cm height above the ground and can be taken into consideration as a second order function. Over 40 m height the changing is linear and over 500 m height the changing is very small, the measured value of vertical...

The goal of this work is to develop an atraumatic stent concept for percutaneous aortic valve replacement. Shape setted braided nitinol wires, thanks to their specific geometry and elasticity, allows stent's compressibility, self deployment and aortic root preservation. Prototypes manufacturing technique and relatives constraints are presented. Performance of the obtained prototypes are evaluat...

In the past decade, an unmanned aerial spraying system (UASS) was applied more and widely for low-volume pesticides operations in China. However, UASS have a higher drift risk due to fine droplets sprayed with working height faster driving speed than ground sprayers. Study on spray is new hot spot within field of pesticide application technology. The test bench originally designed measurement p...
