Belt-like tin oxide (SnO2) materials are synthesized by electrodeposition and thermal oxidation method. The microparticles of 5–20 µm in length size 300-800 nm thickness. electrical properties anode based on such structures studied using an impedance spectroscopic technique. SnO2 particles characterized scanning electron microscopy spectroscopy. Electrochemical tests performed belt-like as the ...

This paper describes the "scissor-knot-pusher," an instrument that greatly facilitates the execution of knot tying during laparoscopic operations. The instrument acts in essence as an extension of the surgeon's hand and, given its rigid structure, allows the surgeon full control of the process of knot tying. Additionally, after the knot has been tightened, it is possible to cut the suture witho...

Scissor lifts, a staple of mechanical design, especially in competitive robotics, are a type of linkage that can be used to raise a load to some height, when acted upon by some force, usually exerted by an actuator. The position of this actuator, however, can affect the mechanical advantage and velocity ratio of the system. Hence, there needs to be a concrete way to analytically compare differe...

Rotationally resolved nonresonant two-photon mass analyzed threshold ionization ~MATI! and zero kinetic energy ~ZEKE! photoelectron spectra of CH2CO 1 and CD2CO 1 are reported. The spectra are dominated by the origin band and totally symmetric a1 vibrations, n4 ~C5C symmetric stretch! and n2 ~C5O asymmetric stretch! for CH2CO , and n1 ~C5O asymmetric stretch!, n3 ~C5C symmetric stretch!, and n4...

The present study compared the muscle activity elicited by selected abdominal training devices with muscle activity elicited by a traditional crunch. Forty-six adults participated in the study. The exercise devices tested included the Ab-ONE, Perfect Abs Roller, Ab Scissor, Ab Swing, 6SecondAbs, and the Torso Track. For those devices with variable resistances, all were tested at their high resi...
