In pavement design, the CBR and direct shear tests are two very common laboratory investigations for predicting the strength of a subgrade layer. The relationship between the CBR and water content has been commonly presented in analyses, with the result of the direct shear being expressed from the aspect of effective cohesion and the internal friction angle. Even though most natural soil is in...

Despite increasing application of the pre-grafting expansion during autologous fat transplantation in breast reconstruction, little is known about its mechanism of action. To address that, ventral skins of miniature pigs were treated over a 10-day or 21-day period, with continuous suction at -50 mm Hg via a 7-cm diameter rubber-lined suction-cup device. Soft tissue thickness increased immediate...

BACKGROUND During orthopedic operations, such as total hip replacement or total knee replacement, there is a lot of bone debris from bone cutting and reaming that commonly causes surgical suction devices to occlude many times, which can prolong the operative time and increase the amount of bleeding for the patient. MATERIALS AND METHODS We developed a surgical filter suction system that we ca...

The crystallization behaviour during low temperature annealing of samples the Zr59.3Cu28.8Al10.4Nb1.5 (at%) bulk metallic glass produced by suction casting and laser powder bed fusion (LPBF) process were studied with small angle neutron scattering (SANS), X-ray diffraction scanning electron microscopy. in-situ SANS measurements isothermal reveals that phase separation in LPBF processed material...

We previously developed an in vivo tissue suction-mediated transfection method (denoted as the tissue suction method) for naked nucleic acids, such as plasmid DNA (pDNA) and small interfering RNA (siRNA), in mice. However, it remains unclear whether the suction pressure conditions affect the results of this method. Therefore, in the present study, we assembled a computer system to control the s...

The development of automation has penetrated into all areas life, including household appliances. One them is robot technology for cleaning floors. With relatively small dimensions, this floor can reach under a table or bed. This equipped with microcontroller, suction pump and ultrasonic sensor to detect obstacles when scanning the surface. microcontroller will process readings. If an obstacle ...

Results of high-order direct numerical simulations are summarized for the evolution of crossflow disturbances in incompressible wing-generic boundary-layers with suction at the wall. The concept of smart suction, an adapted combination of the upstream-flow-deformation (UFD) technique and suction, is presented for laminar flow control. In the UFD technique, relatively tightly spaced, useful cros...
