Optical Measurement of Mass Flow of a Two-Phase Fluid

Density and mass flow are estimated from wavelength-dependent scattering of light. An optoelectronic system utilizes wavelength-dependent scattering of light for measuring the density and mass flow of a two-phase fluid in a pipe. The apparatus was invented for original use in measuring the mass flow of a twophase cryogenic fluid (e.g., liquid hydrogen containing bubbles of hydrogen gas), but underlying principles of operation can readily be adapted to non-cryogenic two-phase fluids.

New Analgesic Actives

A company is looking for the next generation in analgesics. There are several fine analgesics on the market, both by prescription and over the counter, that vary in dosage load, dosage form, molecular size, speed of effectiveness, and side effects or toxicity (if any). New actives in the realm of analgesia are sought, and the form of their delivery is open. Certain aspects of the new analgesic are of particular interest, including speed of effectiveness, toleration, and (shelf-life) fragility.

In-Process Detection of Defects During Welding

Technology is required to enable “in-process” or real-time detection of defects during the welding process. This could be achieved by a system that can monitor any combination of accessible parameters during the weld process and then by analyzing changes, ascertain the presence of a weld defect, its locations, and, if possible, its nature. Potential solutions should be suitable for industrial production lines. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

Up to Ten-Fold Production Increase for Deep, Heavy-Oil Fields

In oil field tests over 18 months, Direct Current Electrical Stimulation has shown up to a 10X increase in oil production for deep, heavy oil. The predominant method for recovering heavy oil is steam, but steam is limited to depths of 2,500 feet. There are no inherent depth limitations to Direct Current Electrical Stimulation. This patented technology — electrically enhanced oil recovery — uses direct current electricity to both heat and electrochemically upgrade the oil in situ, allowing for economical recovery.

All-Natural Preservative

White mustard essential oil (WMEO) is an all-natural extract from white mustard seeds that delivers broad antimicrobial efficacy against bacteria, yeast, and mold, providing a natural and effective alternative to synthetic or artificial preservatives. WMEO has broad application in beverages, meats, poultry, salads, gravies, and sauces. Maltodextrin and white mustard essential oil are both listed in the Code of Federal Regulations as GRAS (Generally Recognized As Safe) for use in food products.

Correction of Retardation and Autism in Mice Points to Human Treatment

Mark Bear (right), director of thePicower Institute and PicowerProfessor of Neuroscience), andGu¨l Do¨ len, a graduate student atBrown University, report the correctionof fragile X syndrome inmice. (Donna Coveney)Researchers at MIT’s Picower Institute for Learning and Memory have corrected key symptoms of mental retardation and autism in mice. Their findings indicate that a certain class of drugs could have the same effect in humans.
