Abstract: A method for the selection of shrimp having a genetically-transmitted favorable growth characteristic for improved aquacultured shrimp production. A genetic marker for the favorable characteristic is prepared by isolating (Penaeus) shrimp nuclear DNA by extraction with chloroform in the presence of cetyl trimethyl ammonium bromide, digesting the DNA with one or more restriction enzymes, and identifying characteristic restriction fragments. The marker is hybridized to a nuclear nucleic acid molecule isolated from (Penaeus) shrimp for the selection of shrimp having the desired characteristic. The marker can be a labelled probe or a primer for amplification and subsequent detection of a gene that encodes a protein promoting the desired growth characteristic. The selected shrimp can be used to produce a high quality, genetically superior seedstock or larvae useful for the economic production of aquacultured shrimp.

Abstract: A non-invasive system for measuring the concentration of an analyte, such as glucose, in an absorbing matrix is described. The system directs beams of light at the matrix using an analyte sensitive wavelength and an analyte insensitive wavelength. The principles of photoplethysmography are applied to measure the change in light intensity caused by matrix absorption before and after the blood volume change caused by the systolic phase of the cardiac cycle. The change in light intensity is converted to an electrical signal which is used to adjust the light intensity and as a measure of analyte concentration.

Abstract: A combined electrohydrodynamic (EHD) and dielectrophoretic (DEP) cooling approach for a processor or similar electronics in a zero gravity environment is beneficial in space exploration. An EHD pumping mechanism is defined by an array of alternating, polarized electrodes surrounding a heat sink coupled to the processor for heat exchange, such as a thermally conductive layer or coating. The array may be circular, rectangular, or any suitable geometry, generally guided by a shape of the heat sink/processor. Cooling fluid is drawn or pumped towards the heat sink by EHD electrodes, and a dielectrophoretic (DEP) electrode disposed above the center of the heat sink extracts the generated vapor bubbles away from the heated surface with a diverging electrical field. One configuration calls for a radial arrangement of EHD electrodes drawing the cooling fluid towards a centrally located heat sink.

Abstract: Nanoimprint lithography forms a microfeature array on a substrate responsive to inkjet printing techniques for high resolution printing of circuit elements and other features with highly accurate fidelity to predetermined boundaries. The microfeature array is defined by micropillars formed between intersecting microchannels in the substrate. The micropillars are responsive to a sequence of ink droplets in a highly controlled and predictable manner based on the droplet volume, droplet spacing and temperature. The flow of liquid ink is restrained by the micropillars for pinning the ink for avoiding uncontrolled ink flow as occurs on a flat surface. Subsequent layers of deposited ink tend to follow pining of previous layers, allowing an iterative buildup of layers for forming a trace of sufficient thickness and a high aspect ratio allowing traces extending above the depth of the microchannels for aiding communication with surface mount components.

Abstract: An electrohydrodynamic (EHD) drying apparatus includes a non-uniform electric field resulting from an electric field source operable for a high potential, and an electric field source operable for a low potential. A power source is connected to the electric field sources for producing the non uniform electric field for inducing dielectrophoresis (DEP) in an article within the uniform electric field. In particular configurations, the applied non-uniform electric field is for separating a vapor phase being formed during drying from the liquid phase. The electric field source defines a polarizer adapted to produce dielectrophoresis, and the electric field induces coupled electrostatics and momentum for disposing liquid towards the high electric field for drying.

Abstract: A strain gauge device employs a reflective base adapted to reflect a divergent optical signal, and a glass tube attached to the reflective base for optical communication therewith, the glass tube having a working length into which an optical fiber is inserted. The optical fiber is configured for transporting an optic signal indicative of the detected strain. The optic fiber has an outside diameter slightly smaller than an inside diameter of the glass tube for providing a slight tolerance. A distal end is disposed in slidable communication with an interior of the glass tube and accommodated by the tolerance, and a sensing circuit at the proximate end receives an optical signal indicative of strain or displacement. A resilient buffer layer made of soft silicone is disposed outside the glass tube to allow for large deformation measurements and reduce the distortion of the deformation by the introduction of the sensor.

Abstract: A protective headgear device, or helmet, protects against head injuries such as concussions and CTE by imposing a network of constant force members (CFMs) between an outer impact shell and an inner fitted capsule engaging the skull/head surface. CFMs exhibit a force absorbing behavior that differs from conventional linear spring behavior that impose a counterforce proportional to the displaced distance. CFMs occupy a compact void between the outer impact shell and the inner fitted capsule by component miniaturization and tethers that redirect forces within the void. An absence of conventional foam and straps increases accommodation for the CFMs and connection tethers/attachments. The CFMs exhibit a substantially constant force that avoids a sharp impactful response associated with head injuries.

Abstract: Catalyst composition and parameters for catalytic hydrothermal liquefaction of biomass to bio-oil fuels target municipal solid waste (MSW) rather than lignin rich plant waste typically sought for bio-oil production. An HTL (Hydrothermal Liquefaction) reactor generates bio-fuel from municipal solid waste (MSW), including receiving, in the HTL reactor, non-lignin based waste from a municipal processing stream, and adding a solvent for extracting sugars from green waste components of the municipal processing stream. The reactor extracts a liquid from the received waste, and converts water soluble products in the liquid into oil soluble products via C-C (carbon-to-carbon) coupling reactions. A catalyst added to the resulting aqueous stream recovers a beneficial oil product, and is optimized by tuning acid and base sites on the solid catalyst.
