Abstract: A microfluidic device includes a plurality of reaction wells; and a plurality of solid supports, and each of the solid supports has a reagent attached thereto. The reagent is attached to the solid support via a labile reagent/support bond such that the reagent is configured to be cleaved from the support via a cleaving operation.

Abstract: A method of operating an electro-permanent magnet may include switching the electro-permanent magnet from an on state wherein magnetic fields of switching and permanent magnets combine to generate a first magnetic field having a first magnitude and a first polarity to a reversed state having a second polarity wherein magnetic fields of the switching magnets and the permanent magnets combine to generate a second magnetic field having a second magnitude less than the first magnitude and a second polarity different than the first polarity. The electro-permanent magnet may be switched from the reversed state to an off state wherein magnetic fields of the switching and permanent magnets combine to generate a third magnetic field having a magnitude that is no more than 50 percent of the second magnitude. Related electro-permanent magnets are also discussed.

Abstract: The presently disclosed subject matter relates to a microfluidic device for measuring an amount of a molecular species in a sample. The device comprises a body and an electrode assembly, the electrode assembly comprising at least one electrode coupled to the body. The device also includes a gas permeable membrane disposed on at least one electrode and a detector for measuring a current at each of the electrodes. Further, the device comprises a channel defined between a substantially planar substrate and planar cover glass. The presently disclosed subject matter also relates to methods of making the microfluidic device.

Abstract: A mechanism for a sliding-pin type disc brake assembly provides a gap between a brake pad and the rotor. The mechanism includes a bushing that receives a sliding pin and a resilient element between the end of the pin and the end of the bushing. The pin reciprocates in the bushing during operation of the brakes, and the bushing moves along the bore as the brake pads wear.

Abstract: The method of root stock propagation involves positioning a collar loosely about a root stock grown from a bud grafted to a seedling wherein the bud is from a clone having desired characteristics. A fruiting scion may be grafted to the root stock such that after controlled growth, the seedling, root stock, collar and fruiting scion if attached, may be transplanted as a body. The root stock grows to a size inside the collar causing the collar to gradually constrict flow of nutrients to the seedling and promotes rooting of the root stock itself while gradually destroying its vascular connection to the seedling. The seedling finally disintegrates and there is left a properly rooted plant having the desired characteristics determined by the bud from the clone.
