A system and method for an MRI apparatus includes an MRI system having a computer programmed to initiate a first scan procedure to acquire MR data and locate a feature of interest of the object, initiate a second scan procedure when a feature of interest of the object is located, and determine if an anomaly of the feature of interest exists. The polymers of the invention are useful for the modification of material surfaces and are particularly suitable for providing biomedical articles such as contact lenses with a hydrophilic coating. A method of producing a novel nanobimorph structure with integrated electrodes is also provided. The objective of reduced scrap rate is thus accomplished by maintaining a ratio of mass to surface area of the sprockets being cast to no greater than about 4 grams of material to each square inch of surface area and alternatively provide through bores through the rim sprockets which additionally assist in wood chip removal. The DC-DC converter further comprises a biasing circuit for biasing a first node and a second node with a first biasing voltage and a second biasing voltage. The locking unit supports the tine and may be cylindrical, rectangular or on a perpendicular support face normal to a radial plane through the axial centerline of the nut thread.
