摘要:
Methods and systems are provided for improving fluid usage while addressing knock by adjusting the use of spark retard and direct injection of a fluid based on engine operating conditions and the composition of the injected fluid. One or more engine parameters, such as EGR, VCT, boost, throttle position, are coordinated with the direct injection to reduce torque and EGR transients.

This invention presents a new cDNA amplification method. RNA is first converted to cDNA. The synthesis of cDNA can include a promoter tagged oligonucleotide, and then this cDNA is ligated to form circles (or possibly concatemers). This is then amplified using a Phi29 DNA polymerase based rolling circle and strand displacement amplification. The invention allows for RNA promoter sequences to be attached to the cDNA to facilitate additional amplification through the generation of RNA from the amplified cDNA. The resulting product can then be used to make materials for gene expression studies or other RNA analysis procedures.

Disclosed herein are sprayable insect repellent compositions that provide improved skin feel through the incorporation of a powder ingredient. The powder is essentially permanently suspended in the composition by a thickener (e.g. carbomer thickener) so that no shaking to resuspend settled out powder is necessary immediately before the composition is applied to the skin. This is achieved in an aerosol or spritz spray formulation, while avoiding clogging problems. One composition contains ethanol, DEET or picaridin, carbomer thickener, a neutralizer, corn starch powder, water, and gas propellant.

A microreplicated article having a moiré reducing surface and method of manufacturing the same, are disclosed. A microreplicated article includes a flexible substrate having first and second opposed surfaces, a first coated microreplicated pattern on the first surface, and a second coated microreplicated pattern on the second surface. The first coated microreplicated pattern and the second coated microreplicated pattern are registered to within 10 micrometers in a machine direction and a transverse direction and the first coated microreplicated pattern and second coated microreplicated pattern form a plurality of lens segments. Each lens segment includes a plurality of lens elements each having an optical axis where all of the lens element optical axes are parallel to each other and lens elements within a first lens segment have optical axes that are offset from optical axes of lens elements within an adjacent second lens segment.

Methods and systems for evaluating a material sample is provided. The system includes a material sample holder including a first flange having an aperture therethrough, a second flange having an aperture therethrough, the first and second flanges configured to frictionally hold a material sample sandwiched therebetween, a waveguide coupled to a first end of each of the first flange and the second flange, each waveguide configured to direct electromagnetic waves through respective apertures, a waveguide adapter communicatively coupled to a second end of each waveguide, and a control unit electrically coupled to the wave source, the control unit configured to control the waveguide adapter to transmit and receive electromagnetic wave signals.
摘要:
A landfill cover composition comprising a concentrate formulated to include a hardening agent, a thickener and emulsifier, and a super absorbent polymer, mixable with water and a filler material, such as cellulose or wood fiber mulch. A mixture of water, filler material and concentrate is sprayed on the surface of a landfill refuse layer and hardened to provide at least a temporary cover as an alternative to a significantly thicker or deeper layer of conventional soil or earth cover. The biodegradable composition preferably includes Plaster of Paris and guar gum compositions and cross-linked sodium acrylate polymer fines, mixed with the filler material and water at a landfill site for reducing transportation and handling costs.
摘要:
A device and method of operation for filling medicine capsules, in which a fixed quantity of open capsules to be filled are supported in a circular array by a holder plate beneath the periphery of a rotatable distribution drum. In use, a measured supply of filling medication, in dry granular form, is dispensed into the center of the rotating drum where it is distributed evenly by centrifugal force along the periphery of the drum. As the drum stops rotating, the medication flows by gravity into the capsules, which are then inspected, closed and packaged. The distribution of filler material is more even than if the capsules were filled by hand, and the average quantity (both by volume and by weight) of the filling material per capsule in the batch is variable to suit an individual patient's needs, and very accurately known. In addition, two or more compatible filler medications may be mixed in the same capsules to suit the specialized needs of a particular user. Because the provided quantity of medication is completely distributed into each batch of capsules, inadvertent double-filling is prevented.
