Dual Mode Dielectric Resonator Filters without Iris
Published Tuesday, April 30, 1996Microwave narrow band-pass filters are used in a large variety of applications ranging from consumer electronics such as direct broadcast receivers and cellular telephones, to phased-array radar systems and satellite transponders. Currently, dual mode microwave filters require that physically adjacent dielectric resonators be coupled to each other...

Pulsed Continuum Source-Diode Array Detector Multielement Atomic Absorption (AAS) Spectrometer
Published Tuesday, April 30, 1996Today, trace metals are being quantified at the ultra-trace level. Existing systems make accurate determinations at these levels laborious and predominantly single element processes, as typified by current commercially available atomic absorption spectroscopy (AAS) instruments. These instruments use a different hollow cathode lamp (HCL) for each...

Mouse Monoclonal Antibody (Mab) Against Ehrlichia Risticii
Published Tuesday, April 30, 1996Researchers at the University of Maryland, Department of Veterinary Medicine have developed a cell line that produces a monoclonal antibody (Mab) against Ehrlichia risticii which is the causative agent for Potomac Horse Fever. This Mab is well characterized and has high affinity for a specific Ehrlichia risticii protein. It can be used to develop...

Structural Actuation and Sensing through Directional Attachment
Published Tuesday, April 30, 1996For a number of years, researchers have attempted to develop a real-time sensor/actuator for the aerospace and aeronautic industries. However, the previous attempts have not been successful in coupling the actuator/sensor in such a way that its behavior is anisotropic; a requirement for real-time control of the substrate. Intelligent actuation...

Construction of a Strain of E. coli That Can be Used to Select DNA Methyltransferase Clones
Published Tuesday, April 30, 1996Escherichia coli contains several genes, designated mcrA, mcrB and mmr, that are able to destroy DNA that has been methylated at specific sequences. Currently identified known methylase-producing strains have limited commercial value due to their low levels of enzyme production. One solution is to cloning and overexpressing the methylase genes in...

Joint Device for Capacitive Microwave Coupling
Published Tuesday, April 30, 1996It has already been demonstrated that for a number of microwave device applications devices made of metal-oxide superconductors such as YBa2Cu3O7 can have performance superior to those made of conventional metals such as Au or Cu. Some of the major obstacles to their implementation in a wide range of systems applications arise from (1) the costly...

Restriction Enzyme NgoFI
Published Tuesday, April 30, 1996A unique restriction enzyme, NgoFI, was identified in high yeilds from Neisseria gonnorhoea. The recognition sequence of this enzyme has been identified, and the biological properties, stability and yield of the enzyme have been determined. Level of expeseion is very small so the cut and recognition sites are not known.

Superconducting Active Lumped Components for Microwave Device Applications
Published Tuesday, April 30, 1996In general, the size advantage of normal or superconducting lumped components over distributed components makes them attractive for low-frequency (~0.1 - 20GHz) and broad-band microwave circuits.For some applications with more stringent requirements, the use of metal-oxide superconducting materials such as YBa2Cu3O7 is expected to be...

Superconductor/Insulator Metal-Oxide Heterostructures for Electric Field Tunable Microwave Devices
Published Tuesday, April 30, 1996It is desirable to have active circuit elements to be used in superconducting microwave device applications. Among various methods to modulate the microwave response of a circuit (i.e. obtain active response), the electric field induced modulation has clear advantages such as low energy consumption, input-output current isolation and high input...
