Abstract:
An antenna element (10) and a quad- line balun column (12) are described. The antenna includes a plurality of droopy bowtie antenna elements (10) disposed on dielectric block (16) and a feed point. The quad-line balun column (12) includes a central member having dielectric slabs symmetrically disposed on external surfaces thereof. At least one end of the balun is provided having a shape such that conductors on the dielectric slabs of the balun can be coupled to the droopy bowtie antenna elements. The quad- line balun column is mechanically stable facilitates the assembly, and provides coincident phase centres for orthogonal dipoles. Thze antenna element provides broad bandwidth, high cross -polarization isolation characteristic and is mechanically stable.
Abstract:
The present invention relates to methods of screening for antifungal agents by identifying agents that bind to or otherwise inhibit indole-3 -acetic acid (IAA) or that bind to or otherwise inhibit the expression or activity of a protein within the Yap family or a gene encoding a protein within the Yap family.
Abstract:
A method for locating a transmitter using a receiver which include, but are not limited to the steps of transmitting a plurality of distinctive and orthogonally polarized signals from a transmitter; receiving the transmitted signals at a pair of separated antennas; demodulating the distinctive orthogonal signals received at each of the pair of separated antennas; and determining a direction to the transmitter from the signals received at the pair of antennas. The system for determining the location of a transmitter using a receiver includes, but is not limited to, having a transmitter adapted for orthogonally transmitting a plurality of distinctive signals; a receiver having a pair of separated antennas for receiving the orthogonally transmitted signals; separate demodulators in the receiver for each antenna of the pair of separated antennas for demodulating the distinctive signals; and signal processing circuitry in the receiver adapted for using the demodulated distinctive signals for determining a direction to the transmitter.
Abstract:
The invention provides methods for rapid, continuous generation of cells and cell products using magnetically stabilized three-dimensional tissue culture. The invention also pertains to a continuous flow self-regulating closed system bioreactor system for magnetically stabilized three-dimensional tissue culture. The methods described here do not use traditional solid scaffolding for cell culture.
Abstract:

Abstract:
A global computer network method and apparatus for creating and deploying many types of self-tutoring systems across many different platforms is disclosed. A run time engine supports several types of tutorials, in both a client and server context. A Builder enables development and testing of tutorials, formed of teacher composed problems, or an existing approved problems set, or student-user composed problems. The system simplifies the process of tutorial construction to allow educators and students with little or no ITS experience to develop content of problems and teaching strategies (i.e., format of problems including hints, messages and sequencing of related problems). The system provides a Web based interface as a means to build and store these tutorials. A web based reporting component allows for live database reporting to teachers, showing how students are performing. A testing component is web based and allows a teacher to test the quality of student composed problems. Further, the testing component allows addition of the student content to the existing approved problem set as is pertinent. Automated analysis and reporting of experimental tutorials developed by either teacher or student is included.

A sensor fabricated from a self assembled monolayer of said compound on gold, exhibiting sensitivity and selectivity for ammonium ions over other ions in aqueous solutions, including blood. A method of preparation of said compound and said sensor.
Abstract:
In various aspects are provided a microfluidic and/or nanofluidic sensor that can provide an indication of the reliability of its measurement of the presence of an analyte in a sample under investigation, an analyte concentration in the sample under investigation, or both. The provided sensors, microfluidic devices, and methods of analyte detection, utilize two transduction mechanisms from the same molecule to determine analyte presence, analyte concentration, or both. An analyte sensing molecule is used that can provide both an optical signal and electrochemical signal when an analyte is recognized by an analyte binding portion of the sensing molecule.
Abstract:
A hydrogen producing reactor is disclosed. The hydrogen producing reactor has a reaction chamber containing a catalyst bed adapted to produce reaction products con-taining hydrogen from a hydrogen-producing feedstock. The reaction chamber also in-cludes a hydrogen-selective, hydrogen-permeable gas separation module adapted to re-ceive the reaction products from the catalyst bed and to separate a product stream con-taining hydrogen from the reaction products. The gas separation module comprises a porous substrate, an intermediate porous layer located at the porous substrate, and a hy-drogen-selective membrane overlying the intermediate layer. The intermediate porous layer comprises a powder having a Tamman temperature higher than the Tamman tem-perature of the porous substrate. A steam reforming process is also disclosed using the disclosed reactor.
