Abstract: A method is disclosed for the Agrobacterium-mediated germline genetic transformation of soybean. The method is based on an Agrobacterium-mediated gene delivery to individual cells in a freshly germinated soybean meristem, wherein cells are induced directly to form shoots and give rise to transgenic plants. This method does not involve a callus-phase tissue culture and is rapid and efficient.

Abstract: A variable capacity swash plate type compressor 10, which incorporates an inlet port 40 disposed in a crankcase 36 leading to a crank chamber 38.

Abstract: Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general. In addition, a particular method and apparatus are disclosed in which electroporation and/or mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both are sought.

Abstract: A piston having anti-rotation for a swashplate compressor includes a body portion extending axially and a connecting portion spaced radially from a longitudinal axis of the body portion and extending axially. The piston also includes a pair of opposed anti-rotation wings extending radially from one end of the body portion between the connecting portion and the longitudinal axis of the body portion.

Abstract: A variable capacity swash plate type compressor 10 incorporates a pressure relief valve 43 in fluid communication with a suction chamber 20 and a crank chamber 40. The pressure relief valve 43 prevents over pressurization in the crank chamber 40 to minimize friction and forces acting on the components of the compressor 10.

Abstract: A control strategy for a multiple stage rotary compressor having compressive capacity output based on the demand of an air conditioning system. The constant variance in capacity to meet demand is obtained by recirculation of the multiple stages. Capacity is reduced to less than full capacity by recirculating the output of each stage back to the input of that particular stage. Capacity is increased up to full capacity by decreasing recirculation of the output of each stage back to the input of that particular stage. Additional stages and or portions operate in the same manner and provide further recirculation variability to provide a recirculation schedule based on demand.

Abstract: An optical fiber having a thermally expanded multiple core section. One such multiple core section may be fabricated by fusing together non-etched multiple fiber claddings resulting in the multiple cores having expanded mode fields that are positioned in close proximity to each other in a common cladding, without signal coupling between the cores. The close proximity of the cores having expanded mode fields may allow for tighter alignment of light waves propagated from one core to other cores.
