Results with newer bladeless LASIK equivalent to standard microkeratome LASIK
...Clinic study comparing femtosecond (bladeless) and mechanical
microkeratome LASIK surgeries has found equal resu..., and replacing the flap. In standard LASIK with a mechanical
microkeratome, the flap is created by a blade; in bladeless LASIK, the newer type, the flap is creat...
A new math model finds that the cochlea's spiral shape enhances low frequencies
...an elastic membrane that runs down its length. The mechanical
properties of this "basilar" membrane vary from very stiff at the outer end and becomes increasingly flexible as the chambers narrow. These changing properties cause the waves to grow and then die away, much as ocean waves get taller and narrower in ...

Child safety seats reduce risk of death in crashes more than seat belts alone
...for the adult-sized seat belt, thereby affording a mechanical
protection advantage over seat belts," the researchers write. "If restraint systems are seriously misused, however, their safety performance would be expected to be diminished." Based on past and these current findings, the authors state that effort...

Manual vs device-assisted CPR
...clusions drawn from two studies examining use of a mechanical
CPR device for the resuscitation patients with out-of-hospital sudden cardiac arrest. One study concluded the device was beneficial, while the other concluded it may be harmful. Lewis and Niemann deal with several questions raised by the research, ...
Mixed results comparing use of manual vs. automated chest compression following cardiac arrest
