Abstract: The present invention relates to the elucidation of specific molecular features of endogenous 2-oxoacid molecules and their derivatives for activating hypoxia-inducible gene expression by inactivating hypoxia-inducible factor hydroxylating enzymes. This invention identifies agents that can be used to induce tissue vascularization, treat anemias, induce tolearance to stroke and heart attacks, improve tissue healing and improve organ transplantation.

Abstract: A method of reducing odors from dewatered biosolids cake includes adding an aluminum-containing compound to digested wastewater sludge prior to dewatering, thereby binding odor-causing proteins with the aluminum-containing compound.

Abstract: Pond filters are generally discussed herein with particular discussions extended to pond filters having a filter mode and a backflush mode. In accordance with aspects of the present invention, the pond filters incorporate a flow controller positioned inside a housing capable of being manipulated using a control knob located on the outside of the housing. The control knob moves a flow gate to direct incoming fluid flow to flow along a first direction for filtering or a second direction for backflushing the filter cartridge.
