Invention Title:听Filtration system and methods of using such system for improved water filtration听

Date of Patent:听 March 10, 2020

滨苍惫别苍迟辞谤蝉:听听Vijaya Rangari, Boniface Tiimob, Vitus Apalangya, Shaik Jeelani, and Temesgen Samuel

础产蝉迟谤补肠迟:听A water filtration system is provided that comprises a combination of two components: silver nanoparticles immobilized on a porous carbon solid matrix and calcium carbonate silver nanoparticles. The silver nanoparticles immobilized on the porous carbon solid matrix are prepared in a one-step wet ball milling process that does not use an environmentally hazardous reducing agent or an organic stabilizer. The calcium carbonate in the calcium carbonate silver nanoparticles is preferably isolated from egg shells. The two filter components can be present in any ratio but an approximate 50:50 ratio is preferred. Also provided is an in situ method of preparing silver nanoparticles on active charcoal. Powdered activated charcoal and silver nitrate are mixed together in a mixture of ethanol and water to form a charcoal-silver nitrate solution which is then subjected to ball milling in the presence of polypropylene glycol to produce silver nanoparticles on active charcoal.

Invention Title:听 Internal combustion engine propulsion method and corresponding transmission design听

Date of Patent:听 May 21, 2019

滨苍惫别苍迟辞谤:听听ShaoWei Gong

础产蝉迟谤补肠迟:听A case-emphasized propulsion method improves vehicle fuel efficiency. The ratio of the most-used speed to the most-desired speed of an IC engine is employed to control the engine to always run at its optimal working state with an efficient single-stage gear transmission. The propulsion method used with different brands of IC engines demonstrates a reduction in fuel consumption between 5 and 39%. An n-ratio automatic single-stage gear transmission implements the propulsion method. The transmission design executes the proposed propulsion method as well a continuous transmission, but it can also increase the propulsion efficiency about 8 to 18% when applied to replace traditional automatic transmissions or continuously variable transmissions in vehicle drivetrains.听

础产蝉迟谤补肠迟:听 Disclosed are novel primers for use in the molecular detection of food-threat agents and food-borne pathogens. The primers may be used in combination for the rapid, high-throughput screening PCR-based techniques to simultaneously detect multiple food safety biothreat agents. The multiplex-detection methods have improved sensitivity and specificity for the detection of multiple high-impact food-borne pathogens simultaneously. Real-time PCR assaying techniques using such primers include microarrays and multiplex single-tube arrays, the latter optionally simultaneously with TaqMan probes.

Abstract:听 The present disclosure describes a viscometer for measurements of both Newtonian and non-Newtonian fluids. In one embodiment, the viscometer comprises (i) a storage reservoir to store a test fluid, (ii) at least one drain tube assembly comprising a capillary drain tube, (iii) a collector for collecting said test fluid, and (iv) a detector. In addition, its novel viscosity equations suitable for the described viscometers are provided and illustrated for the application to Newtonian fluids and non-Newtonian fluids.

Invention Title:听 Lytic Peptideshaving Anti-Proliferative Activity Against Prostate Cancer Cells

Patent Date:听 6/11/2013

听 听听 听

Inventors: Clayton Yates, Timothy Turner, and Jesse Jaynes

础产蝉迟谤补肠迟:听 Lytic peptides, including fusion peptides of lytic peptides conjugated with luteinizing hormone-releasing hormone or modified versions thereof to target luteinizing hormone-releasing hormone receptors, are disclosed. The lytic peptides show anti-proliferative activity against human prostate cancer cell lines, but are nontoxic to normal primary human prostate epithelial cells or to bone marrow stromal cells in co-culture. The lytic peptides have specificity for and anti-proliferative activity against prostate cancer tumor cells, and low toxicity for normal prostate cells, making the peptides useful in therapies for prostate cancer.

Invention Title: Recovery of Phosphorus from Poultry Litter

Patent Date:听 1/20/2015

Inventor: Kokoasse Kpombluekou-A

Abstract:听 A chemical extractant selected from solutions of K₂SO₄ and/or Na₂SO₄ can be used by contacting with untreated broiler litter to selectively and efficiently remove phosphorous from the broiler litter. The broiler litter and extractant solution mixture, after a suitable time, can be separated, such as by filtration. The resulting treated broiler litter is thus significantly lower in P content without being lower by an undesirable amount in more preferred minerals. The treated litter so obtained is suitable for crop soil augmentation. Further, phosphorous can be thereafter precipitated in the form of phytic acid. Since the precipitate is high in mineral content, it can be used for other purposes (e.g., plant food, etc.).

Invention Title: Chemokine Derived Peptides that bind with Chemokine Receptor CXCR3 and Uses for Chronic Wound and Angigenesis Inhibition Treatments

Patent Date:听 5/27/2014

听 听听 听

Inventors: Cecilia Yates-Binder, Timothy Turner, Alan Wells, Jesse Jaynes, Richard Bodnar

Abstract:听 Disclosed are peptides having activity against receptor CXCR3 are disclosed that exhibit activity in preventing the formation of new vessels and activity in mediating the dissociation of newly-formed vessels and resolving of wounds in the later stages of wound healing. Preferred peptides are derived from the 伪-helix portion IP-10 (CXCL10) or from IP-9 (CXCL11), are nontoxic, and smaller than naturally occurring peptides, making them useful in therapies against diseases or disease states marked by unwanted angiogenesis, including tumorogenic diseases such as cancers, and in healing of chronic wounds.

Invention Title: Nanostructured Thermoplastic Polymide Films
听
听Patent Date: 5/19/2015

Abstract:听听 Structured films containing multi-walled carbon nanotubes (鈥淢WCNTs鈥�) have enhanced mechanical performance in terms of strength, fracture resistance, and creep recovery of polyimide (鈥淧I鈥�) films. Preferably, the loadings of MWCNTs can be in the range of 0.1 wt % to 0.5 wt %. The strength of the new PI films dried at 60掳 C. increased by 55% and 72% for 0.1 wt % MWCNT and 0.5 wt % MWCNT loadings, respectively, while the fracture resistance increased by 23% for the 0.1 wt % MWCNTs and then decreases at a loading of 0.5 wt % MWCNTs. The films can be advantageously be created by managing a corresponding shift in the annealing temperature at which the maximum strength occurs as the MWCNT loadings increase.

Invention Title: Railroad Rail Head Repair
听
Patent Date: 6/7/2016

Inventor: Heshmat Aglan

Abstract :听A multi-pass gas metal arc weld (鈥淕MAW鈥�) approach is used for in-situ repair of railhead defects. A defect is removed via machining a perpendicular slot or grove in the railhead leaving the web and base unaltered. A sufficient number of GMAW passes are used to fill the slot using a weld material suitable for the particular type of parent steel, and excess weldment can be removed. Optionally, for pearlitic steel rails post-weld heat treatment can be used to cause austenization and/or quenching of the weld. The weld heat inputs and other parameters are controlled to avoid ductile and brittle fracture related morphologies.

Title:听听Movable root contact-pressure plate assembly for hydroponic system

Patent Date:听 8/29/1989

Inventors:听 Walter Hill, Carlton Morris, Conrad Bonsi, and Philip Loretan

Abstract

A hydroponic system for growing sweet potatoes and other root and tuber crops includes a growing channel incorporating a movable root contact/pressure plate assembly. The assembly consists of a flat, rigid PVC plate in which holes for inserting plants are drilled and a flexible vinyl film which is secured along the length of each side edge of the plate, by means of pressure fit connectors. The assembly is secured to the top edges of a growing channel, again by pressure fit connectors. The flexible film suspends the plate near and parallel to the bottom of the growing channel, with the flexibility of the film allowing upward movement of the plate within the channel as the plant roots grow. The assembly provides contact and pressure to the plant roots inside the growing channel thereby promoting enlargement of the roots. This enlargement causes the assembly to move upwardly, thereby maintaining the desired pressure conditions during growth. A suitable nutrient solution is supplied in the growing channel.
