Abstract: A device for producing circularly polarized optical emission includes a light emitting semiconductor heterostructure, further including at least one semiconducting layer; a ferromagnetic contact having a magnetic moment, in electrical contact with a layer of the semiconductor heterostructure; and a contact electrically connected to a different region of the semiconductor heterostructure. This light emitting semiconductor heterostructure may be a light emitting diode (LED), or some other structure. The ferromagnetic contact injects spin polarized carriers (electrons or holes) into the semiconducting device, which recombine with their opposing carriers to produce circularly polarized light. A process for producing circularly polarized optical emission includes applying a bias across a light emitting semiconductor heterostructure having a contact with a net magnetic moment, therby injecting spin polarized carriers into the light emitting semiconductor heterostructure.

Abstract: Antigens derived from Taenia crassiceps have been isolated which have specificity and sensitivity in their reactivity with antibodies against Taenia saginata and Taenia solium. These antigens may therefor be used in diagnostic testing for the serological screening of livestock for cysticercosis, rather than relying upon methods involving dissection and visual examination.

Abstract: A cart is provided for delivering fluid to vehicles including aircraft. The fluid can be, e.g., engine oil or hydraulic fluid. The cart has a tank, mounted to a carriage mounted in turn to carrying wheels. The cart has as a dispensing means, a hose ending in a nozzle. Fluid, e.g. oil is added to the tank, followed by an inert gas, e.g., N.sub.2, which pressurizes the tank to about 120 psi. The cart is wheeled to an aircraft and oil delivered to its engines through the dispense means. Such delivery system replaces delivery by quart cans or by mechanical pumps, which have had inefficiency, waste and contaminant drawbacks.

Abstract: Phythophthora species which infect potatoes may result in the devastating disease potato late blight or in pink rot. Primers specific for Phythophthora infestans (late blight), and for Phytophthora erythroseptica and Phytophthora nicotianae (pink rot) have been designed which are useful for detecting the presence of the microorganisms by polymerase chain reaction methods. The primers were derived from the internal transcribed spacer region of Phytophthora ribosomal DNA and may be used to confirm the presence of the microorganisms or to distinguish among them.

Abstract: A collapsible training projectile includes a nose, a body and a tail. The dy has a forwardmost end secured to the nose, and a rearwardmost end secured to the tail. The body further includes one or more axial, longitudinal slots that extend radially through at least part of the body, such that when the projectile impacts with an object, the kinetic energy causes the body to plastically deform along the slots, thereby reducing the penetration energy of the projectile. In another embodiment, the projectile includes a wedge, a body and a tail. The forwardmost end of the body is secured to the wedge, and its rearwardmost end is secured to the tail.

Abstract: The large area plasma processing system (LAPPS) is a system wherein an elron beam is used to produce a plasma. A large area uniform plasma is produced where length and width can be comparable (10's-100's of cm) and very much larger than the plasma thickness (.about.1 cm). The plasma distribution is created independent of the surface to be processed and the bias applied to the surface. The beam-produced plasma has a low intrinsic electron and excitation temperature plasma, allowing the process to be conducted with better control of free radical production. A material, such as a substrate, being processed may be placed in close proximity to plasma with controlled ion bombardment or without substantial bombardment by energetic ions. The system also offers a large available area for gas inflow and removal from the processing chamber and cathode chamber so as not to contaminate the material being processed or damage the cathode.

Abstract: An apparatus for producing an acoustic output in an underwater environment ncludes a radiator having a generally elongate, circular x-section with first and second ends, the outer surface of the radiator having a curved shape; an end cap attached to each end of the radiator; and a plurality of piezoceramic elements positioned and arranged to form stacks located exterior to the radiator and between the end caps. The radiator and the end caps seal off the interior of the radiator and provide an air tight cavity interior to the radiator. When a fluctuating voltage is applied across the piezoceramic stacks, the stacks are caused to longitudinally expand and contract in concert with the applied voltage thus inducing a displacement of the end caps. Since the ends of the radiator are attached to the end caps, the radiator is caused to flex inwardly and outwardly as the end caps move longitudinally.

Abstract: A high energy density electrochemical capacitors with electrodes is formed from proton inserted ruthenium oxides (e.g. HRuO.sub.2.xH.sub.2 O or HRuO.sub.2). The electrode material is formed by reducing ruthenium oxides (e.g. RuO.sub.2.xH.sub.2 O or RuO.sub.2) using electrochemical method or chemical reaction between ruthenium oxides with acetone or methanol. Electrochemical capacitors with electrodes formed of proton inserted ruthenium oxides possess higher energy density, lower resistance, broader operating temperature range, and longer lifetime than that with electrodes comprised ruthenium oxides.

Abstract: The inventive fatigue-testing apparatus features a compact orbital mechan which rotates a bending force around a non-rotating test section and a stationary test bed. In addition to applying a bending force, some inventive embodiments apply an axial force and a torsional force, thereby accomplishing full-scale evaluation of test sections under three-dimensional loading; the inventive practice for applying bending, torsional and axial loads compares favorably with conventional practice in terms of reliability and cost. The inventive orbital mechanism increases the reliability of the entire inventive test apparatus by reducing the number of moving parts, component wear, maintenance and complexity. The invention also provides maximum access to the test section for instrumentation, inspection, maintenance and modification. The inventive benefits will permit evaluations of larger test sections and will afford extended evaluations to more accurately determine fatigue limitations of complex joints.

Abstract: A method of preventing tumor cell metastasis by inhibiting the binding of hepatocyte growth factor/scatter factor ("HGF/SF") with met proto-oncogene protein is described. A method of producing HGF/SF and a cell line for the production of HGF/SF are also described. The met proto-oncogene tyrosine kinase receptor (Met) and its ligand, hepatocyte growth factor/scatter factor (HGF/SF), ordinarily constitute a paracrine signalling system in which cells of mesenchymal origin produce the ligand, which binds to the receptor that is predominantly expressed in cells of epithelial origin. The method of the present invention disrupts the Met-HGF/SF autocrine signaling that contributes to the tumorigenic process in tumors of mesenchymal origin, such as sarcomas.

Abstract: A trimode fuze is provided which comprises a combination of a standard dual ode fuze with the addition of a void sensing mechanism. The modified fuze provides detonation of a warhead under three distinct scenarios: impact upon a hard target with detonation caused by the deformation of the warhead, displacing the hard target firing pin, penetration and continuous deceleration within a solid target with detonation caused by the expiration of a penetration delay timer, and penetration of a soft target with detonation caused by the transition from a target impact deceleration to the lower preset deceleration threshold.The first two modes of detonation are similar to those found in prior art dual mode fuzes. The third mode is brought about when target impact deceleration causes compression of a spring. As the spring compresses, steel balls slide out of a locking mechanism.
