A golf swing alignment and swing-aiming device is disclosed. An embodiment of the device includes a main elongated member, an aim arm that is pivotally connected to the main elongated member, an aiming strip that is pivotally connected to the aim arm, and a ball positioning arm that is pivotally connected to the main member at a location near the second end of the main member. The device collapses so that it can fit inside a club sheath in a golf bag, and can be unfolded to allow the user to position the aiming strip in a parallel arrangement with the main member, so that the aiming strip can be used to guide the swing of a golf club while positioning one's feet along the main member.

Contaminated fluids are treated by adsorbing contaminant onto a sorbent to concentrate the contaminant and then oxidizing the contaminant via the Fenton and related reactions. Iron is attached to the sorbent or can be added in solution with an oxidant. Both systems, iron attached to the sorbent or iron in solution, can be used to oxidize contaminants on or near the surface of the sorbent. The process can be used to treat contaminated water in above-ground and below-ground treatment systems, as well as contaminated gases.

A method for recovering silver from a refractory manganese dioxide-silver ore. The ore is contacted with an effective amount of a culture of direct manganese-reducing Bacillus polymyxa bacteria. The ore-bacteria mixture is maintained at an approximately neutral pH until a sufficient amount of the manganese dioxide in the ore is reduced from Mn(IV) to Mn(II). The silver present in the ore is then recovered by conventional methods such as cyanide leaching.
