| Number | Title | Issue Date |
| 8012932 | Contraceptives based on SP22 and SP22 antibodies Oral, topical and injectable contraceptives, which are based on sperm protein 22 kDa (SP22) polypeptides and antibodies and infertility diagnostics are provided. ... | 09/06/2011 |
| 7811460 | Process and apparatus for removal of biocolloids from water Biocolloids, e.g. Cryptosporidium parvum oocysts, are removed from water by filtration using a packed bed of a granular filter medium, preferably MgO, establishing an electric field across the packed bed, perpendicular to the flow of the water through the pac... | 10/12/2010 |
| 7754212 | Contraceptives based on SP22 and SP22 antibodies Oral, topical and injectable contraceptives, which are based on sperm protein 22 kDa (SP22) polypeptides and antibodies and infertility diagnostics are provided. ... | 07/13/2010 |
| 7485233 | Hydrophilic mixed matrix material having reversible water absorbing properties Polymer-ceramic mixed matrix compositions contain one or more organic polymers and a nano-sized dispersion of inorganic metal oxide particles which are dispersed throughout the composition. Materials have use in making membranes that act as transfer agents. ... | 02/03/2009 |
| 7388381 | High resolution geoelectrical probe A in situ probe for the measurement of the geoelectrical properties of a geological formation. The probe serves as the interface between a standard acquisition system and the earth. The probe is customizable in its length and the type of electrodes used to make cont... | 06/17/2008 |
| 7325465 | Particle matter sampling method and sampler with a virtual impactor particle concentrator An apparatus for sampling ambient air to obtain coarse and fine fractions of particulate matter includes a single acceleration tube and a collection tube coaxially arranged along a central axis with a gap between facing distal ends thereof within a range of d/D1 | 02/05/2008 |
| 7166228 | Method of treating a subsurface formation with ferrous iron to reduce contaminants to harmless species A method for treating a subsurface formation with a ferrous compound, to reduce a contaminant therein, involves introducing into the subsurface formation a ferrous compound in combination with sodium hydrosulfite in an amount sufficient to substantially prevent prec... | 01/23/2007 |
| 6881364 | Hydrophilic mixed matrix materials having reversible water absorbing properties Polymer-ceramic mixed matrix compositions contain one or more organic polymers and a nano-sized dispersion of inorganic metal oxide particles which are dispersed throughout the composition. Materials have use in making membranes that act as transfer agents. ... | 04/19/2005 |
| 6855498 | In-situ hybridization probes for the detection of microsporidial species The present invention provides in situ hybridization probes which include a marker and a nucleic acid molecule able to hybridize exclusively with only one species of Encephalitozoon. The nucleic acid molecule may be, for example, complimentary to segment 878-... | 02/15/2005 |
| 6821425 | Biomass concentrator reactor A gravity-flow Biomass Concentrator Reactor (BCR) is provided which uses a porous barrier having pore sizes averaging from about 1 to about 50 microns through which treated water permeates under the pressure of gravity. Solids suspended in water treated with the BCR... | 11/23/2004 |
| 6663781 | Contaminant adsorption and oxidation via the Fenton reaction Contaminated water is 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... | 12/16/2003 |
| 6655402 | System and method for vacuum flushing sewer solids A flushing system and method are provided for substantially reducing sewer solid accumulation in urban drainage systems such that their performance is optimized, their structural integrity is substantially maintained, and pollution of receiving waters is ... | 12/02/2003 |
| 6387652 | Method of identifying and quantifying specific fungi and bacteria Fungi and bacteria can be detected and rapidly quantified by using the nucleotide sequences taught here that are specific to the particular species or group of species of fungi or bacteria. Use of the sequences can be made with fluorescent labeled probes,... | 05/14/2002 |
| 6197940 | Method for evaluating and affecting male fertility A 22 kD sperm protein, SP-22, correlates with fertility and predicts fertility in males. The protein can be assayed to detect decreases in fertility resulting from exposure to toxicants and pollutants which are known or suspected to decrease fertility. If... | 03/06/2001 |
| 6117328 | Adsorbent-filled membranes for pervaporation Pervaporation membranes are used for removing volatile organic compounds from wastewaters. These pervaporation membranes are prepared by dispersing at least one hydrophobic adsorbent such as activated carbon uniformly into a polymer matrix.... | 09/12/2000 |
