Method and system for magnetic resonance imaging
Parallel transmit Magnetic Resonance MR scanner used to image a conductive object such as an interventional device like a guidewire within a subject. This is achieved by determining which Radio Frequency RF transmission modes produced by the parallel RF transmission elements couple with the conductive object and then transmitting at significantly reduced power so as to prevent excessive heating of the conductive object to an extent that would damage the surrounding tissue of the subject, for example, the coupling RF transmission modes may be generated at less than 30%, preferably around 10% of the normal power levels that would conventionally be used for MR imaging. However, even at these low power levels sufficient electric currents are induced in the conductive device to cause detectable MR signals; the location of the conductive object within the subject can thus be visualised. By fast alternate, or simultaneous, iterative application of low-power coupling mode and normal-power non-coupling modes, both the subject and the conductive object can be imaged. During the calibration step of determining which RF transmission modes couples with the conductive object, instead of physically measuring the current induced in the conductive object using sensors, imaging the conductive object using additional very short series of flip angle RF pulses (vLFA) gives a good approximation of the coupling matrix. |

Aerodynamic sampling of particles and vapors from surfaces for real-time analysis
A non-contact aerodynamic sampling tool for collecting particles and vapors from the surfaces. Opposing planar jets or planar jet arrays are used to liberate material from surfaces so that particulate matter and vapors can be collected for analysis in real time. High-speed valves may be triggered to create pressure waveforms for high velocity pressurized planar jet bursts, or continuously operated opposing wall jets may be angularly directed toward a target surface, permitting sampling from large standoff distances. The wall jets traverse the surface and exhibit significant drag forces to lift particles into a suction intake. Unlike axisymmetric jets, the wall jets sustain the flow momentum over the target surface for a greater distance, dislodging particles submerged in the boundary layer and significantly improving particle resuspension and vapor collection. Real-time analysis and detection of target analytes are achieved by efficient sample liberation from the surface in the sampling tool and the efficient sample delivery to an analytical module. |

Low thermally conductive spacer for hot and cold feedline insulation
The invention provides improvements on thermal performance of multilayer insulation for hot and cold feedlines. Insulation on feedlines has always been problematic, and can perform ten times worse than tank insulation contributing as much as 80% of total system heat leak. The poor performance of traditional MLI wrapped on feed lines is due to compression of the layers, causing increased interlayer contact and heat conduction. The MLI performance is not only much worse than expected, but also difficult to predict. Spacer structures are presented which provide a well-defined, accurately characterized support between the thermal radiant barriers in a multilayer insulation. The invention provides a robust, structural insulation that is much less sensitive to wrap compression and installation workmanship allowing for more predictable, higher performance insulation structure. |

This invention relates to methods for increasing carbon fixation and/or increasing biomass production in a plant, comprising: introducing into a plant, plant part, and/or plant cell heterologous polynucleotides encoding (1) a succinyl CoA synthetase, (2) a 2-oxoglutarate:ferredoxin oxidoreductase, (3) a 2-oxoglutarate carboxylase, (4) an oxalosuccinate reductase, or (5) an isocitrate lyase, or (6) a succinyl CoA synthetase and a 2-oxoglutarate:ferredoxin oxidoreductase, (7) a 2-oxoglutarate carboxylase and an oxalosuccinate reductase polypeptide, and/or (8) a 2-oxoglutarate carboxylase polypeptide, an oxalosuccinate reductase polypeptide and an isocitrate lyase polypeptide to produce a stably transformed plant, plant part, and/or plant cell, wherein said heterologous polynucleotides are from a bacterial and/or an archaeal species. Additionally, transformed plants, plant parts, and/or plant cells are provided as well as products produced from the transformed plants, plant parts, and/or plant cells. |

Benzylisoquinoline alkaloid (BIA) precursor producing microbes, and methods of making and using the same
Methods and engineered yeast cells for generating a benzylisoquinoline alkaloid product are provided herein. A method comprises providing engineered yeast cells and a feedstock to a reactor. In the reactor, the engineered yeast cells are subjected to fermentation by incubating the engineered yeast cells for a time period to produce a solution comprising the BIA product and cellular material. The solution comprises not more than one class of molecule selected from the group of protoberberine, morphinan, isopavine, aporphine, and benzylisoquinoline. Additionally, at least one separation unit is used to separate the BIA product from the cellular material to provide the product stream comprising the BIA product. |
