Abstract: Zirconium phosphate particles are synthesized by providing a solution of zirconium oxychloride in an aqueous solvent, adding at least one oxygen-containing additive to the solution, the oxygen-containing additive being selected to form a complex with zirconium ions in the solution of zirconium oxychloride and thereby reduce hydration of the zirconium ions, and combining this solution with phosphoric acid or a phosphoric acid salt to obtain zirconium phosphate particles by sol gel precipitation.

Abstract: Epidermal growth factor (EGF) produced by an excretory recombinant approach was tested for its efficacy in treating various skin wounds. In a randomized double blind controlled study, local cream samples prepared with human EGF at a final concentration of as low as 0.02% (g/g) in topically suitable carrier were found to have an enhancing effect on the recovery of diabetes foot ulcers. This promotional effect is statistically significant and has resulted in a reduced mean healing time of over 3 weeks when compared with that of control. Both the 0.02% (g/g) and 0.04% (g/g) human EGF supplemented samples in comparison with control showed a trend of stimulatory effect when a recovery of 50% of an ulcer was considered. The EGF samples were also shown to be highly effective in promoting treatments of wounds resulting from bedsores and surgeries.

Abstract: A system for controlling the aerobic phase of a wastewater treatment cycle in a sequencing batch reactor, comprising a tank, an air blower, at least one sensor for measuring the concentration of dissolved oxygen in the tank, and means to control the length of time that the air blower introduces air into the wastewater and to maintain at a constant level the volume of air introduced per time by the air blower. The length of time that the air blower introduces air is determined by the change in the slope of the curve representing the concentration of dissolved oxygen in the wastewater. The volume of air to be introduced per time by the air blower is determined based on the average concentration of dissolved oxygen from the previous wastewater treatment cycle.

Abstract: A mode selector mechanism is provided for a rotary power tool for selecting between an impact mode and a drill mode. The power tool includes a housing, a motor oriented in the housing, an input shaft and an output shaft both rotationally mounted in the housing. An impact mechanism connects the input shaft to the output shaft for imparting a rotary impact to the output shaft when the torque load exceeds a predetermined torque capacity of the impact mechanism. A stopping member is shiftable by a user between a first orientation that permits the impact mechanism to operate in the impact mode and a second orientation that prevents a coupler of the impact mechanism from retracting, thus maintaining the connection of the input shaft and the output shaft in the drill mode.
